For the graph, find the average rate of change on the intervals given

See attached picture b

Answer:

Step-by-step explanation:

First, we need to find the median of each series.

For series a, the median is:

(3680 + 3682)/2 = 3681

For series b, the median is:

(382 + 408)/2 = 395

Next, we calculate the deviation of each value from its respective median:

For series a:

|3487 - 3681| = 194

|4572 - 3681| = 891

|4124 - 3681| = 443

|3682 - 3681| = 1

|5624 - 3681| = 1943

|4388 - 3681| = 707

|3680 - 3681| = 1

|4308 - 3681| = 627

For series b:

|487 - 395| = 92

|508 - 395| = 113

|620 - 395| = 225

|382 - 395| = 13

|408 - 395| = 13

|266 - 395| = 129

|186 - 395| = 209

|218 - 395| = 177

Then, we calculate the mean deviation for each series by adding up the absolute deviations and dividing by the number of values:

For series a:

Mean deviation = (194 + 891 + 443 + 1 + 1943 + 707 + 1 + 627)/8

= 682.5

For series b:

Mean deviation = (92 + 113 + 225 + 13 + 13 + 129 + 209 + 177)/8

= 115.5

Comparing the two mean deviations, we see that series a has a larger mean deviation than series b. This indicates that series a has more variability than series b.

we can see, the function f(x) = 3x - 5 produces the desired range for the given domain.

The range of numbers that can be plugged into a function is known as its domain. The x values for a function like f make up this collection.(x). A function's range is the collection of values it can take as input. After we enter an x number, the function outputs this set of values.

The function that produces the range of {−11,−5,1,7,13} given a domain of {−2,0,2,4,6} is:

f(x) = 3x - 5

To see why, we can plug in each value from the domain into the equation and see if it produces the corresponding value in the range:

f(-2) = 3(-2) - 5 = -11

f(0) = 3(0) - 5 = -5

f(2) = 3(2) - 5 = 1

f(4) = 3(4) - 5 = 7

f(6) = 3(6) - 5 = 13

As we can see, the function f(x) = 3x - 5 produces the desired range for the given domain.

Step-by-step explanation:

The formula to calculate the value of the account after t years, with principal P and annual percentage rate (APR) r compounded n times per year, is given by:

A = P(1 + r/n)^(nt)

In this case, P = $690, r = 0.022 (2.2% expressed as a decimal), n = 4 (compounded quarterly), and t is the number of years.

So the function to calculate the value of the account after t years is:

A(t) = 690(1 + 0.022/4)^(4t)

Simplifying and rounding to four decimal places, we get:

A(t) = 690(1.0055)^4t

To find the annual percentage yield (APY), we use the formula:

APY = (1 + r/n)^n - 1

In this case, r = 0.022 and n = 4, so:

APY = (1 + 0.022/4)^4 - 1

= 0.022321

Multiplying by 100 and rounding to two decimal places, we get an APY of 2.23%.

The correct answer is:

The equation is [tex]7(c-0.75) = 2.80[/tex], and the regular price of a cookie is [tex]c =\$1.15[/tex].

Explanation:

c is the regular price of a cookie. We know that today they are $0.75 less than the normal price; this is given by the expression [tex]c-0.75[/tex].

We also know if we buy 7 of them, the total is $2.80. This means we multiply our expression, [tex]c-0.75[/tex], by 7 and set it equal to $2.80:

[tex]7(c-0.75) = 2.80[/tex]

To solve, first use the distributive property:

[tex]7 \times c-7\times0.75 = 2.80[/tex]

[tex]7c-5.25 = 2.80[/tex]

Add 5.25 to each side:

[tex]7c-5.25+5.25 = 2.80+5.25[/tex]

[tex]7c = 8.05[/tex]

Divide each side by 7:

[tex]7c\div7 = 8.05\div7[/tex]

[tex]c = \$1.15[/tex].

Using triple angle formula the evaluation of the trigonometric identity cos(2a) are 1 and 1/2.

We can use the trigonometric identity cos(2a) = 1 - 2sin^2(a) to evaluate cos(2a), but first we need to find the value of sin(a) from the given equation.

Given: sin(3a) = 2sin(a)

We can expand sin(3a) using the triple angle formula:

[tex]sin(3a) = 3sin(a) - 4sin^3(a)[/tex]

Substituting the given equation into this, we get:

[tex]2sin(a) = 3sin(a) - 4sin^3(a)[/tex]

Simplifying, we can rearrange to get:

[tex]4sin^3(a) - sin(a) = 0[/tex]

Factorizing, we get:

[tex]sin(a)(4sin^2(a) - 1) = 0[/tex]

So, either sin(a) = 0 or 4sin^2(a) - 1 = 0.

If sin(a) = 0, then

[tex]cos(a) = \±1\\cos(2a) = cos^2(a) = 1.[/tex]

If 4sin^2(a) - 1 = 0, then we can solve for sin(a) to get:

[tex]sin(a) = \±\sqrt{(1/4)} = \±1/2[/tex]

If sin(a) = 1/2, then

[tex]cos(a) = \sqrt{(1 - sin^2(a))} = \sqrt{(1 - 1/4)} = \sqrt{3/2}[/tex]

Using the identity cos(2a) = 1 - 2sin^2(a), we can then calculate:

[tex]cos(2a) = 1 - 2sin^2(a) = 1 - 2(1/4) = 1/2[/tex]

If sin(a) = -1/2, then cos(a) = -√3/2, and using the same identity we get:

[tex]cos(2a) = 1 - 2sin^2(a) = 1 - 2(1/4) = 1/2[/tex]

So, we have two possible values for cos(2a): 1 and 1/2.

D 20

Step-by-step explanation:

Let's call the integer we're looking for "x". We know that 18% of x is greater than 3.5, so we can write the inequality:

To solve for x, we can divide both sides by 0.18:

x > 3.5 ÷ 0.18

x > 19.44

We want the smallest possible integer that satisfies this inequality, which is 20. So the answer is D) 20.

The volume of the solid generated by revolving the region enclosed by the curves y = 4 - 2x², y = 0, x = 0, and y = 2 through 360° about the y-axis is (16/3)π cubic units.

To find the volume of the solid generated by revolving the region enclosed by the curves y = 4 - 2x², y = 0, x = 0, and y = 2 through 360° about the y-axis, we use the formula:

V = ∫[a,b] πr²dy

where a and b are the limits of integration in the y-direction, r is the radius of the circular cross-sections perpendicular to the y-axis, and V is the volume of the solid.

First, we need to find the equation of the curve that is generated when we rotate y = 4 - 2x² around the y-axis. To do this, we use the formula for the equation of a curve generated by revolving y = f(x) around the y-axis, which is:

x² + y² = r²

where r is the distance from the y-axis to the curve at any point (x, y).

Substituting y = 4 - 2x² into this formula, we get:

x² + (4 - 2x²) = r²

Simplifying, we get:

r² = 4 - x²

Therefore, the radius of the circular cross-sections perpendicular to the y-axis is given by:

r = √(4 - x²)

Now, we can integrate πr²dy from y = 0 to y = 2:

V = ∫[0,2] π(√(4 - x²))²dy

V = ∫[0,2] π(4 - x²)dy

V = π∫[0,2] (4y - y²)dy

V = π(2y² - (1/3)y³)∣[0,2]

V = π(8 - (8/3))

V = (16/3)π

Therefore, the volume of the solid generated by revolving the region enclosed by the curves y = 4 - 2x², y = 0, x = 0, and y = 2 through 360° about the y-axis is (16/3)π cubic units.

b. To find the volume of the solid generated by revolving the region enclosed by the curves x = √y+9, x = 0, and y = 1 through 360° about the y-axis, we use the same formula as in part (a):

V = ∫[a,b] πr²dy

where a and b are the limits of integration in the y-direction, r is the radius of the circular cross-sections perpendicular to the y-axis, and V is the volume of the solid.

First, we need to solve the equation x = √y+9 for y in terms of x:

x = √y+9

x² = y + 9

y = x² - 9

Next, we need to find the equation of the curve that is generated when we rotate y = x² - 9 around the y-axis. Using the same formula as in part (a), we get:

r = x

Now, we can integrate πr²dy from y = 1 to y = 10 (since x = 0 when y = 1 and x = 3 when y = 10):

V = ∫[1,10] π(x²)²dy

V = π∫[1,10] x⁴dy

V = π(1/5)x⁵∣[0,3]

V = π(243/5)

Therefore, the volume of the solid generated by revolving the region.

Step-by-step explanation:

Let X be the lifespan of an item. We are given that X is normally distributed with a mean of μ = 5 years and a standard deviation of σ = 1.3 years.

We want to find the probability that an item will last longer than 6 years. Let Y be the random variable that represents the lifespan of an item in excess of 6 years, i.e. Y = X - 6. Then we want to find:

P(Y > 0)

Using the properties of normal distribution, we can standardize Y to get a standard normal variable Z:

Z = (Y - μ) / σ = (X - 6 - 5) / 1.3 = (X - 11) / 1.3

So we want to find:

P(Z > (6 - 11) / 1.3) = P(Z > -3.85)

Using a standard normal distribution table or calculator, we can find that the probability of Z being greater than -3.85 is very close to 1 (in fact, it is essentially 1). Therefore, the probability of an item lasting longer than 6 years is essentially the same as the probability of Y being greater than 0, which is 1.

Therefore, the probability that a randomly purchased item will last longer than 6 years is approximately 1.

Step-by-step explanation:

Got it right on edmentum.

The graph that matches the piecewise function, f(x) = √(x + 5), if x < -2, f(x) = |x + 1| if -2 ≤ x ≤ 2, and f(x) = (x - 2)² if x > 2 is the graph in the third option.

A piecewise function is a function is a function that consists of two or more subfunctions each of which are applied, based on the specific interval of the input variable.

The intervals of the piecewise function are;

f(x) = √(x + 5) if x < -2

f(x) = |x + 1| -2 ≤ x ≤ 2

f(x) = (x - 2)² if x > 2

The graph of the piecewise function is a three piece graph which consists of the graph of f(x) = √(x + 5), for x values less than -2, f(x) = |x + 1|, for x-values in the interval -2 ≤ x ≤ 2 and the graph of f(x) = (x - 2)²

The <-2, symbol indicates the presence of an open circle in the graph of f(x) = √(x + 5) at x = -2

The interval -2 ≤ x ≤ 2 for the function f(x) = |x + 1| indicates that the graph of f(x) = |x + 1| in the interval -2 ≤ x ≤ 2, consists of closed circles at x = -2 and x = 2.

The interval, x > 2, for the function, f(x) = (x - 2)², indicates that the presence of an open circle in the graph of f(x) = (x - 2)² at x = 2.

The correct option for the graph of the piecewise function is therefore the third option.
