0. 75 0. 721 73/100

Answers

Answer 1

The numbers ordered from least to greatest are 0.721, 73/100, and 0.75.

0.75, 0.721, 73/100

we can convert the fraction 73/100 to a decimal by dividing 73 by 100, which gives us 0.73.

0.721 < 0.73 < 0.75

"Least" is a mathematical term used to refer to the smallest value in a given set of numbers or a range of values. It is the opposite of the term "greatest," which refers to the largest value in the set. To find the least value in a set of numbers, you can sort them in ascending order and select the first or smallest number. Alternatively, you can use mathematical formulas or functions such as the minimum function to determine the least value.

In algebra, finding the least common multiple (LCM) or least common denominator (LCD) involves identifying the smallest multiple or denominator that two or more numbers or expressions have in common. This is essential in simplifying and solving complex equations and expressions. In geometry, the least distance between two points is the straight line or path that connects them and is the shortest possible route between them. This concept is fundamental in navigation and optimization problems.

What is the average rate of change for this function for the interval from x = 3
to x = 5?

Answers

The average rate of change for the exponential function over the interval from x = 3 to x = 5 is 12.

Calculating the average rate of change

The average rate of change for an exponential function can be found by dividing the change in y-values over the change in x-values for the given interval.

For the interval from x = 3 to x = 5, the change in x-values is 5 - 3 = 2.

The corresponding y-values for x = 3 and x = 5 are

y = 8 and y = 32, respectively.

Therefore, the change in y-values over the interval is 32 - 8 = 24.

The average rate of change for the exponential function over the interval from x = 3 to x = 5 is:

Average rate of change = Change in y-values / Change in x-values

Average rate of change = 24 / 2

Average rate of change = 12

Hence, the average rate of change for the exponential function over the interval is 12

In ABC, D is a point on AB and E is a point
on AC such that DE is parallel to BC. If AE = 3,
EC = x, ED = x + 1, and CB = x + 5, find the
length of EC. [Only an algebraic solution will be
accepted.]

Answers

The required value of EC is 5 units.

How to find the value of EC?

Since DE is parallel to BC, we can use the property of similar triangles to set up a proportion:

AD/DB = AE/EC

We know that AD + DB = AB = x + 5. Since D is a point on AB, we can express AD and DB in terms of x:

AD = x, DB = x + 5 - x = 5

We also know that AE = 3 and ED = x + 1. Using these values, we can express AD in terms of ED:

AD = ED - AE = (x + 1) - 3 = x - 2

Substituting these values into the proportion, we get:

(x - 2)/5 = 3/EC

Multiplying both sides by 5EC, we get:

x - 2 = 15/EC

Multiplying both sides by EC, we get:

EC(x - 2) = 15

Expanding the left side, we get:

ECx - 2EC = 15

Solving for EC, we get:

EC = 15/(x - 2)

We are given that EC = x, so we can set these expressions equal to each other:

x = 15/(x - 2)

Multiplying both sides by (x - 2), we get:

x(x - 2) = 15

Expanding the left side, we get:

x² - 2x = 15

Bringing all terms to one side, we get:

x² - 2x - 15 = 0

We can factor this quadratic equation:

(x - 5)(x + 3) = 0

Therefore, x = 5 or x = -3. We reject x = -3 since we are given that EC > 0. Thus, the length of EC is: EC = x = 5.

Find the rate of change of the area of a square with respect to the length z, the diagonal of the square. What is the rate when z = 3? a) dA/dz = z; rate = 6 b) dA/dz = zroot2; rate = 3 root2 c) dA/dz = 2z; rate = 3 d) dA/dz = z; rate = 3 e) dA/dz = 2z; rate = 6

Answers

The rate of change of the area of a square with respect to the length z, the diagonal of the square is  dA/dz = 2z; rate = 6. The correct answer is C.

We know that the area A of a square is given by A = s², where s is the length of the sides of the square. Also, we know that the diagonal of the square (z) is related to the sides by the Pythagorean theorem: s² + s² = z² or 2s² = z² or s² = z²/2.

Taking the derivative of both sides of the equation s² = z²/2 with respect to z, we get:

2s ds/dz = 2z/2

s ds/dz = z

Now, since the area A is given by A = s², we can take the derivative of both sides of this equation with respect to z:

dA/dz = d/dz (s²) = 2s ds/dz

Substituting the value of s ds/dz obtained earlier, we get:

dA/dz = 2s (z/s) = 2z

Therefore, the correct option is (c) dA/dz = 2z, and the rate of change of the area of the square with respect to the length z is 2z. When z = 3, the rate of change is 2(3) = 6. So, the answer is (c) dA/dz = 2z; rate = 6.

In order to solve quadratic equations of the type ax2 + bx + c = 0, the quadratic formula is utilised. The equation is:

x = (-b ± √(b² - 4ac)) / 2a

where a, b, and c are constants, x is the variable we're trying to solve for, and sqrt() stands for square root. By solving the quadratic equation's square, one may deduce the quadratic formula. Any quadratic equations, whether they have real or complex roots, may be solved using the same formula.

The given equation in standard form is:

7x² - 6x + 11 = 0

The quadratic formula is given as:

x = (-b ± √(b² - 4ac)) / 2a

Substituting the values a = 7, b = -6, and c = 11.

x = (-(-6) ± √((-6)² - 4(7)(11))) / 2(7)

x = (6 ± √(196)) / 14

x = (6 ± 14) / 14

what is the product of any two invertible matrices is invertible.

Answers

The product of any two invertible matrices is invertible that is (BC) = A⁻¹

Now, let's consider the product of two invertible matrices, say A and B. Since A and B are invertible, they both have an inverse, denoted by A⁻¹ and B⁻¹, respectively.

To show that the product AB is also invertible, we need to find a matrix that satisfies the definition of an inverse. Let's call this matrix C.

If C is the inverse of AB, then we should have:

(AB)C = C(AB) = I

where I is the identity matrix.

Now, we can use the associativity of matrix multiplication to expand the left-hand side of the equation:

(AB)C = A(BC)

Notice that B and C are both matrices, so their product BC is also a matrix. Thus, we can write:

A(BC) = I

Since A is invertible, we can multiply both sides by A⁻¹ to get:

A⁻¹A(BC) = A⁻¹I

The left-hand side simplifies to:

(BC) = A⁻¹

Now, we have found a matrix C that satisfies the definition of an inverse for AB, which means that AB is invertible.

To summarize, the product of two invertible matrices is invertible, and the proof relies on the fact that the inverse of a matrix is unique and the associativity of matrix multiplication.

The midpoint of AB is =M−−6, 2. One endpoint is =A−−8, 7. Find the coordinates of the other endpoint, B

Answers

If the midpoint of AB is =M(−6, 2) and one endpoint is =A(−8, 7), then the coordinates of the other endpoint B is (-4, -5)

To find the coordinates of endpoint B, we can use the midpoint formula, which states that the midpoint of a line segment is the average of the coordinates of its endpoints.

The midpoint formula is

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints.

We know the coordinates of point M, which is the midpoint of the line segment AB:

M = (-6, 2)

We also know the coordinates of one endpoint of the line segment, A:

A = (-8, 7)

Let's use the midpoint formula to find the coordinates of endpoint B:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Substituting the values we know:

(-6, 2) = ((-8 + x2)/2, (7 + y2)/2)

Simplifying

-6 = (-8 + x2)/2 and 2 = (7 + y2)/2

Multiplying both sides of each equation by 2:

-12 = -8 + x2 and 4 = 7 + y2

Adding 8 to both sides of the first equation:

-4 = x2

Subtracting 7 from both sides of the second equation:

-5 = y2

Therefore, the coordinates of endpoint B are B = (-4, -5)

Answers

Answer:

Step-by-step explanation:

For this problem, we set up an equation

You have 40 cents a pound and 149 cents a pound

You need to make 209 pounds of 85 cents a pounded mix.

Our equation will be:

40(209 - b) + 149b = 209 x 85

b represents the number of pounds in the second mix

209-b represents the number of pounds left in the first mix

Simplifying the equation will leave us to:

8,360 - 40b + 149b = 17,765

8,360 + 109b = 17,765

109b = 9,405

b = 86.284404

A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.

The perimeter-

d = √[(x2 - x1)² + (y2 - y1)²]

So, the perimeter of the classroom is:

d1 = √[(-12 - (-12))² + (15 - (-9))²] = √(24² + 24²) = √(2² × 24²) = 48√2

d2 = √[(-12 - 9)² + (15 - 15)²] = √(21²) = 21

d3 = √[(9 - 9)² + (15 - (-9))²] = √(24² + 24²) = √(2² × 24²) = 48√2

d4 = √[(9 - (-12))² + (-9 - 15)²] = √(21²) = 21

perimeter = d1 + d2 + d3 + d4

= 48√2 + 21 + 48√2 + 21

A line's slope might be zero, positive, negative, or undefinable. A line with a positive slope is moving upward from left to right, a negative slope is moving downward from left to right, and a line with a zero slope is level. The line is vertical if the slope is undefinable.

Let us consider the first two points (-3, 0) and (0, -1).

The slope of the line is given as:

m = (y2 - y1) / (x2 - x1)

how to calculate the product of two random variable that follows normal distribution with mean 0 and variance 1

Answers

The product of two random variables that follows the normal distribution with mean 0 and variance 1 is expected 0.

To compute the product of two random variables that are normal distributed with a mean of 0 and a variance of 1, the following procedure can be employed:

Since the mean of the normal distribution is 0 and the variance is 1, we can assume that the standard deviation is also 1.

Thus, we can write the probability density function of the normal distribution as:

f(x) = (1/√2π) * e^(-x^2/2)

Using the definition of expected value, we can write the expected value of a random variable X as:

E[X] = ∫x * f(x) dx, where the integral is taken over the entire range of X.

Similarly, we can write the expected value of a random variable Y as:

E[Y] = ∫y * f(y) dy, where the integral is taken over the entire range of Y.

Since the two random variables are independent, the expected value of their product is the product of their expected values. Thus, we can write:

E[XY] = E[X] * E[Y]

Substituting the probability density function of the normal distribution into the expected value formula, we can write:

E[X] = ∫x * f(x) dx = ∫x * (1/√2π) * e^(-x^2/2) dx = 0

E[Y] = ∫y * f(y) dy = ∫y * (1/√2π) * e^(-y^2/2) dy = 0

Thus, the expected value of the product of two random variables that follow a normal distribution with mean 0 and variance 1 is:

E[XY] = E[X] * E[Y]

= 0 * 0 ⇒ 0

Therefore, the product of two random variables that follow a normal distribution with mean 0 and variance 1 has an expected value of 0.

The U.S. Senate has 100 members. After a certain​ election, there were 10 more Democrats than​ Republicans, with no other parties represented. How many members of each party were there in the​ Senate?

Democrats: ____

Republicans: ____

Answers

In response to the stated question, we may state that As a result, there equation are 55 Democrats in the Senate.

What is equation?

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9". The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

Let's call "x" the number of Republicans in the Senate.

According to the problem, Democrats outnumber Republicans by ten. Therefore "x + 10" represents the number of Democrats in the Senate.

Because the Senate has a total of 100 senators, we may formulate an equation:

x + (x + 10) = 100

To simplify this equation:

2x + 10 = 100

Taking 10 off both sides:

2x = 90

Divide all sides by two:

x = 45

As a result, there are 45 Republicans in the Senate.

To get the number of Democrats, we may insert x = 45 into the following expression:

x + 10 = 45 + 10 = 55

As a result, there are 55 Democrats in the Senate.

Therefore:

a normal distribution is observed from the times to complete an obstacle course. the mean is 69 seconds and the standard deviation is 6 seconds. using the empirical rule, what is the probability that a randomly selected finishing time is greater than 87 seconds? provide the final answer as a percent rounded to two decimal places. provide your answer below: $$ %

Answers

The probability that a randomly selected finishing time is greater than 87 seconds is 14.08%. This can be calculated using the empirical rule.


The empirical rule states that for any data that is normally distributed, about 68% of the data will fall within one standard deviation of the mean (in this case, within 69 ± 6 seconds). Approximately 95% of the data will fall within two standard deviations (in this case, within 69 ± 12 seconds), and about 99.7% of the data will fall within three standard deviations (in this case, within 69 ± 18 seconds).Given the mean and standard deviation given, we can calculate the probability that a randomly selected finishing time is greater than 87 seconds.

We can do this by subtracting the area under the curve from the mean to the value we are interested in (in this case, 87 seconds). Since the total area under the curve is 1, subtracting the area from the mean to 87 seconds will give us the desired probability.To calculate the area under the curve, we need to calculate the Z-score, which is the number of standard deviations away from the mean a particular value is. In this case, the Z-score is (87 - 69) / 6, which is 2.16. Using a Z-table, the probability of a Z-score of 2.16 or higher is 0.8592. Therefore, the probability that a randomly selected finishing time is greater than 87 seconds is 1 - 0.8592, which is 0.1408. Rounding to two decimal places, this is 14.08%.

"g" Which population did the GSS target? Does the data collected by the GSS represent a Simple Random Sample of American adults? Group of answer choices Not quite - it is a more complicated method than a SRS, but the data is representative of all American adults. Yes, it is a fairly simple process to take a true simple random sample of all American adults and the GSS does it every two years. No, this data is not random or representative of all American adults and should not be used for inferences

Answers

The correct answer is option (a) Not quite - it is a more complicated method than a SRS, but the data is representative of all American adults.

The General Social Survey (GSS) is a nationally representative survey of the adult population of the United States. The GSS uses a multistage area probability sample design, which means that the sample is selected in two or more stages, with the first stage being the selection of primary sampling units (PSUs) and the second stage being the selection of households or individuals within PSUs.

While the GSS does not use a simple random sampling method, the survey design is intended to provide a representative sample of the U.S. adult population. The GSS employs a complex sampling design that takes into account stratification, clustering, and oversampling of certain groups, such as African Americans, Hispanics, and Asian Americans. This design is intended to improve the precision of estimates for these groups, which may be small in number in the overall population.

Therefore, the correct option is (a) Not quite - it is a more complicated method than a SRS, but the data is representative of all American adults.

Answers

-5x^2 - 20x- 30, the equation from vertex form to standard form.

What is an equation?

An equation is a mathematical statement containing two algebraic expressions flanked by equal signs (=) on either side.

It shows that the relationship between the left and right printed expressions is equal.

All formulas hav LHS = RHS (left side = right side).

You can solve equations to determine the values ​​of unknown variables that represent unknown quantities.

If a statement does not have an equals sign, it is not an equation. A mathematical statement called an equation contains the symbol "equal to" between two expressions of equal value.

Hence, -5x^2 - 20x- 30, the equation from vertex form to standard form.

""You are not helping," Alicia shrieked.Ron was driving the boat, and he clearly knew what he was doing. He had been running boats, working crab traps since Alicia was old enough to notice such things. Still, she wasn't sure she trusted him to tell her the truth about things. She was younger, and he liked to tease. She often found herself soaking wet from a dunk, or the loser in a game he'd "forgotten" to explain the rules for. She loved him nonetheless. He brought her treasures from his traps. He told her stories of strange creatures he'd seen in the salt marshes."Seriously," Ron continued, slowing the boat down, "they can't really hurt you. It's just a bivalve.""Bivalve means 'two valves,'" Alicia said, "but that doesn't tell me anything about how hard they bite." Spray from the waves speckled Alicia's back and shoulder. She had turned to talk to Ron, but she also was enjoying a break from getting the spray in her face. It was a warm sunny day, but Alicia knew if the wind picked up she could get chilled."Look, it's not going to hurt if you get bitten," Ron said, taking her seriously now. "If you just pick them up from the back you won't have any trouble. Shoot, you pick up crabs all the time and they have a much more painful pinch than a scallop.""Well, there's a bigger place to put my hand on a crab. Scallops are petite.""And squirty," Ron added. "You know they move by pushing water through their shell? But seriously, sis, they move slowly. They will be snuggled down in the sea grass when you see them and won't go far if they do move. You'll be fine. Now climb up on the bow, look out in the shallows, and see if you can see any."Ron had slowed the boat to an almost idle speed. Up ahead Alicia could see many boats anchored on the shallow flats. People walking around the boats would bend every now and then to pick something up from the water. It looked like a small city on the water, with people milling about waiting for a movie to start or a party to begin.Alicia climbed up to the front of the boat and looked out over the sea grass flats. The water was just a few feet deep, and she could see the dark green blades of sea grass swaying as the waves gently washed across the shallows. The boat moved slowly, and Alicia saw shells scattered here and there and sea urchins with their spiny red orbs. Small translucent fish darted away.She had only seen pictures of scallops, but when she saw the first brown shell tucked into a clump of sea grass she knew immediately what it was."I see one," she yelled, pointing."That's great," Ron yelled back. "Wait till you see a lot more than just one. It's not worth stopping for one."Alicia continued looking, scanning first one side of the boat then the other. She saw a stingray dash away, patches of gleaming white sand here and there, and another few sea urchins. Then suddenly, as if they had passed into a new world, scallops were everywhere. Every few feet on both sides of the boat she saw them. Waving her hand at Ron, she turned and got ready to drop the anchor."Here," she said. "Right here is perfect."Ron cut the motor and Alicia dropped the anchor off the bow. She turned. Ron had already put on his tennis shoes and was putting sunblock on his face. He threw the sunblock in her direction, and threw a leg over the side of the boat."Get your shoes on. There's a mesh bag on the seat for you. Use that to collect your scallops. We'll put them in the cooler when the bags get full."Alicia slipped out of the boat a few minutes after Ron. The ground under her feet was squishy but solid; the sea grass brushed her legs. Spotting a nearby scallop, she walked slowly over, reached down-water up to her elbow-and touched its shell. Sure it would squirt away, she was surprised when nothing happened at all. Reaching behind and underneath it, she lifted the scallop out of the water and up to her face to look more closely. The top shell was dark green, almost brown, with tiny barnacles here and there. The bottom shell was white and smooth."Told ya," Ron yelled at her from the other side of the boat. "It's super easy."Just then the scallop she was holding opened its shell slightly. Alicia saw a row of iridescent blue dots among what looked like frilly whiskers. Was it looking at her?Suddenly she felt the scallop contract in her hand. Its shell clamped shut, and water squirted out of it. Right into her face."Ahhh," she screamed, dropping the scallop and hearing Ron's hoots of laughter behind her."And there, dear sister, is the scallop's bite. Do be careful," Ron said, laughing harder.Alicia had to grin as her brother's laugh grew louder. "I'll take a squirt in the face any day over a bite," she said bending to retrieve the dropped bivalve. It was going to be a good day.Why is Ron so knowledgeable about sea animals? aHe likes to eat scallops. bHe spends his time working crab traps. cHe enjoys teasing his sister. dHe likes to show off what he knows. a group of like-minded persons who come together with collective interests to affect policy is known as a(n)?
