Answer 1

Given that he is from the Dominican Republic, the likelihood that the chosen player is a pitcher is roughly 0.053.

what is probability ?

The study of arbitrary events or experiments falls under the purview of probability, a subfield of mathematics. A value between 0 (impossible) and 1 is used to estimate the possibility or chance of an event occurring (certain). Several disciplines, including science, engineering, economics, finance, and more, utilise the idea of probability. It is frequently determined by dividing the number of positive events by the total number of outcomes that could occur.

given

(a) To find P, we can utilize the complement rule (T&D). The addition to T&D is the possibility that the chosen player is a pitcher or a Dominican. We thus have:

The equation P(T&D) = 1 - P(T'UD') = 1 - P(T') - P(D') + P(T'D')

P(T), P(D), and P(TD) are all provided as 0.42, 0.105, and 0.056 respectively. As a result, we may determine the complements' probabilities:

P(T') = 1 - P(T) = 1 - 0.42 = 0.58 P(D') = 1 - P(D) = 1 - 0.105 = 0.895 P(T'D') = P(TD)' = 1 - (P(T) + P(D) - P(TD)) = 1 - (0.471 + 0.42 + 0.105 - 0.056)

By replacing these values, we obtain:

P(T&D) = 1 - 0.58 - 0.895 + 0.471 = 0.046

As a result, there is a 0.046 percent chance that the chosen player is a non-pitcher from outside the Dominican Republic.

(b) In order to determine the likelihood that the chosen player is a pitcher given that he is from the Dominican Republic, we must first determine P(P|D). Bayes' Theorem may be applied:

P(P|D) equals P(D|P)P(P)/P (D)

P(D) = 0.105 and P(TD) = 0.056 are the values provided. Therefore,

P(P) is defined as P(TD') / P(D') = 0.056 / 0.895 0.0626.

P(D|P) is equal to P(T|D) / P(P) = 0.056 / 0.0626 0.895.

By replacing these values, we obtain:

P(P|D) = (0.895)(0.0626) / 0.105 ≈ 0.053

Given that he is from the Dominican Republic, the likelihood that the chosen player is a pitcher is roughly 0.053.

If a certain apple tree grew 2 feet and then tripled its height, it would become 4 feet
shorter than the pine tree that grows on the other end of the street. Which
of the formulas below describes the relation between the height of the apple tree a
and the height of the pine tree p?

A) P-4=3a+2
B) P=2(a+3)+4
C) P=3(a+2)-4
D) P=3a+10

Answers

Answer:

Step-by-step explanation:

C.) P = 3(a+2)-4

The formula which describes the relation between the height of the apple tree and the height of the pine tree p is P=3(a+2)-4, the correct option is C.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

Growth of apple tree= 2feet

Now,

Let's call the original height of the apple tree "h". According to the problem, if the apple tree grew 2 feet and then tripled its height, it would become 4 feet shorter than the pine tree. So we can write:

3(h+2) - 4 = p

Simplifying, we get:

3h + 2 = p

Now we can see that option (D) P=3a+10 is very similar to our expression, but it has a constant term of 10 instead of 2. This constant term does not match the problem statement, which says that the apple tree would be 4 feet shorter than the pine tree, not taller. Therefore, option (D) is not the correct answer.

Option (A) P-4=3a+2 also does not match the problem statement. If we solve for p, we get:

P = 3a + 6

This means that the apple tree would be 6 feet shorter than the pine tree, not 4 feet shorter as stated in the problem.

Option (B) P=2(a+3)+4 also does not match the problem statement. If we solve for p, we get:

P = 2a + 10

This means that the apple tree would be 10 feet shorter than the pine tree, not 4 feet shorter as stated in the problem.

Option (C) P=3(a+2)-4 matches our expression from earlier. If we solve for p, we get:

P = 3a + 2

Therefore, by equation the answer will be P=3(a+2)-4.

Answers

The 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.

Therefore, the answer is option (a) 6.15 and 6.85 hours.

What is confidence interval?

A confidence interval is a statistical range of values within which we can be reasonably confident that the true value of a population parameter lies. It is commonly used in inferential statistics to estimate an unknown population parameter, such as a mean or a proportion, based on a sample from that population.

To calculate the 90% confidence interval for the average number of hours of sleep for working college students, we'll use the formula:

Confidence Interval = Sample Mean ± (Critical Value x Standard Error)

Where:

Sample Mean: 6.5 hours (the average number of hours of sleep)

Critical Value: t-value corresponding to a 90% confidence level with 100 degrees of freedom (101 students - 1)

Standard Error: Standard Deviation / Square Root of Sample Size

Let's plug in the values and calculate the confidence interval:

Standard Error = 2.14 / √101 ≈ 0.2139

Confidence Interval = 6.5 ± (1.660 x 0.2139)

Confidence Interval = 6.5 ± 0.3546

Lower Bound = 6.5 - 0.3546 ≈ 6.1454

Upper Bound = 6.5 + 0.3546 ≈ 6.8546

Rounding to the hundredths place, the 90% confidence interval for the average number of hours of sleep for working college students is between 6.15 and 6.85 hours.

Therefore, the answer is option (a) 6.15 and 6.85 hours.

Answers

Mark needs a total amount of 215 to buy sneakers and we know that his aunt gave him 100 for the same, he also know that he can earn 16 for each hour that he works at his aunt's store, therefore he needs to work 8 hours.

Mark needs a total amount of 215 to buy sneakers and we know that his aunt gave him 100 for the same,

therefore, we can say that 215 - 100 = 115

therefore, Mark now needs only 115 for him to buy sneakers and  now we need to find how many full hours do Mark need to work to buy sneakers:

therefore, we need to divide 115 by 16 to find out the hours he needs to work at his aunt's store:

115/16 = 7.2

we get 7.2 which also means 7 hours 20 mins but we need to find full hours Mark needs to work, that will be:

The outer perimeter is 76.12 ft according to given question.

what is perimeter?

Perimeter is a term used in geometry to refer to the total distance around the outside of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape. For example, in a rectangle, the perimeter is calculated by adding the length of all four sides. In a circle, the perimeter is called the circumference and is calculated as the distance around the edge of the circle.

The perimeter of a semicircle is the sum of the length of its straight edge and half the circumference of the circle.

In this case, the radius of the semicircle is given as 8 units, so the circumference of the corresponding full circle is 2πr = 2π(8) = 16π units.

Half the circumference of the circle is therefore 8π units.

The straight edge of the semicircle is simply the diameter of the circle, which is twice the radius, or 2(8) = 16 units.

So, the perimeter of the semicircle is the sum of the straight edge and half the circumference:

Perimeter = 16 + 8π

Using approximate value for pi (π = 3.14), the perimeter can be expressed as:

Perimeter ≈ 16 + 8(3.14) ≈ 40.12 units.

The perimeter of a rectangle is given by the sum of the lengths of its four sides.

In this case, the length of the rectangle is given as 10 units and its width is given as 8 units.

Therefore, the perimeter of the rectangle is:

Perimeter = 2(Length + Width) = 2(10 + 8) = 2(18) = 36 units.

So, the perimeter of the rectangle with length 10 units and width 8 units is 36 units.

Answers

(a) μx  15.55 cubic feet. The standard deviation is the square root of the variance, i.e., θx = 1.881 cubic feet

The mean, or expected value, of x can be calculated as μx = Σ(xi * P(xi)) where xi are the possible values of x and P(xi) are their corresponding probabilities. Thus, μx = (13.40.2) + (15.80.5) + (19.3*0.3) = 15.55 cubic feet.

To calculate the standard deviation, we first need to calculate the variance, which can be obtained as θ²x = Σ((xi-μx)² * P(xi)). Thus, θ²x = ((13.4-15.55)²0.2) + ((15.8-15.55)²0.5) + ((19.3-15.55)²*0.3) = 3.54.

Therefore, the standard deviation is the square root of the variance, i.e., θx = √3.54 = 1.881 cubic feet (rounded to four decimal places).

The velocity of an object is
v(t) = 36-t^2, 0≤ t ≤ 6
where v is measured in meters per second and t is the time in seconds. Find the velocity and acceleration of the object when t = 3. What can be said about the speed of the object when the velocity and acceleration have opposite signs?

Answers

In calculus, the derivative is a fundamental concept that measures how a function changes with respect to its input variable. It is a mathematical tool used to study the behavior of functions and is used in many areas of mathematics, physics, engineering, and economics.

When t = 3, the velocity of the object is 27 meters per second, and its acceleration is -2 meters per second squared.

When the velocity and acceleration have opposite signs, the speed of the object is decreasing. The acceleration of an object can be calculated using the derivative of the velocity of the object with respect to time.

v(t) = 36 - t², 0 ≤ t ≤ 6

Let us take the derivative of the velocity, v(t), to obtain acceleration, a(t) = v'(t) = -2t.When t = 3, v(3) = 36 - 3² = 27 meters per second.

Therefore, when t = 3, the velocity of the object is 27 meters per second. When t = 3, a(3) = -2(3) = -6 meters per second squared. The object's acceleration is -6 meters per second squared.

The speed of the object is decreasing when the velocity and acceleration have opposite signs.

To construct the graph of the hyperbola, the procedure is as follows:

Marty first identifies the center of the hyperbola as (-5,2), and that the hyperbola opens up and down. Since a = 6, the coordinates of the vertices are (-5, -4) and (-5, 8).The slopes of the asymptotes of this parabola are a = ± 3/4, and the asymptotes pass through the center of the hyperbola. The equations of the asymptotes are y - 2 = ± 3/4(x + 5).

Equation of an hyperbola

The equation of a vertical hyperbola with center (x*, y*) is given according to the following equation:

(y - y*)²/a² - (x - x*)²/b² = 1.

A vertical hyperbola opens up and down.

In this problem, the equation is:

(y + 2)²/36 - (x + 5)²/64 = 1.

Hence the center is:

(-5, 2).

The value of coefficient a is:

a² = 36 -> a = 6.

Then the vertices of the hyperbola are:

(-5, 2 - 6) = (-5,-4).(-5, 2 + 6) = (-5,8).

The slopes of the asymptotes of the parabola are given as follows:

±a/b.

Hence:

a/b = 6/8 = 3/4.-a/b = -6/8 = -3/4.

Since the asymptotes pass through the center, the equation is:

y - 2 = ± 3/4(x + 5).

To find out how much hot chocolate each boy got, we need to divide the total amount of hot chocolate by the number of people sharing it. Since there are two boys, we can divide 15 by 2 to get the amount of hot chocolate each boy received: 15 ÷ 2 = 7.5

Therefore, each boy got 7.5 ounces of hot chocolate to drink while they went sledding.It's important to note that when dividing something equally between two people, we divide by two since there are two individuals.

In this case, each boy received half of the container, or half of the total amount of hot chocolate. This type of division is known as "fair" or "equal" sharing, as both parties receive an equal portion.

Sunflower canola oil is a cooking oil sold in south african supermarkets a 750ml bottle cost R28 and a 2litre bottle cost R63 evaluate which option will be the most cost effective option

Answers

A 2-liter container costs R0.032 per milliliter, which is less than a 750-milliliter bottle, which costs R0.037 per milliliter.

A milliliter is it an ML?

a volumetric measurement using the metric system. One litre is equivalent to 1,000 milliliters. Additionally known as cc, mL, and cubic centimetre.

To evaluate which option is the most cost-effective, we need to calculate the cost per milliliter of each bottle of cooking oil.

For the 750ml bottle, the cost per milliliter is:

R28 / 750ml = R0.037 per ml

For the 2-liter bottle, the cost per milliliter is:

R63 / 2000ml = R0.032 per ml

Therefore, the 2-liter bottle is the more cost-effective option, as it has a lower cost per milliliter than the 750ml bottle. The cost per milliliter of the 2-liter bottle is R0.032, which is cheaper than the cost per milliliter of the 750ml bottle, which is R0.037.

what is equation ?

A mathematical equation is a claim that two expressions are equal, typically represented with an equal sign (=) between them. The terms "left hand side" (LHS) and "right hand side" (RHS) of the equation, respectively, refer to the expressions on either side of the equal sign. Equations are a common tool for problem solving because they may be used to depict relationships between variables or quantities and to determine the value(s) of the unknown variable(s) that satisfies the equation. For instance, the link between the variables x and the integers 2, 5, and 11 is represented by the equation 2x + 5 = 11. Finding the value of x that makes the left and right sides of the equation equal is necessary to solve this equation.

given

A) Rice farming operations release methane into the atmosphere.

B) Methane is created when cows break down cellulose anaerobically.

E) Methane is released into the atmosphere when landfill material decomposes anaerobically.

Any of the aforementioned behaviours would raise the atmospheric methane concentrations and may have an impact on climate change globally.

Methane is a greenhouse gas that causes the atmosphere of the Earth to warm.

It is produced by both natural and artificial processes. Examples of human activities that contribute to methane emissions into the atmosphere include the production of rice, cattle digestion, and landfill decomposition.

which degenerate conic is formed when a double cone is sliced at the apex by a plane perpendicular to the base of the cone?

Answers

When a double cone is sliced at the apex by a plane perpendicular to the base of the cone, the resulting conic section is a parabola.

Option B is the correct answer.

We have,

A parabola is a type of conic sect ion that can be defined as the locus of points equidistant from a fixed point (the focus) and a fixed line (the directrix).

In the case of slicing a double cone at the apex, the resulting conic section will have the characteristic shape of a parabola.

The slicing plane intersects both sides of the double cone, creating a curved shape that opens upward or downward, depending on the orientation of the cone.

The vertex of the parabola corresponds to the point of intersection of the slicing plane with the double cone.

Therefore,

When a double cone is sliced at the apex by a plane perpendicular to the base, a parabola is formed.

An Ixl question from sixth grade IXL:FF.15 Rectangles: relationship between perimeter and area

Answers

The dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.

What is perimeter of a rectangle?

The distance around a rectangle's outside edge is known as its perimeter. It is computed by summing the measurements of the rectangle's four sides. The perimeter P of a rectangle with sides of length l and width w is given by:

P = 2l + 2w.

By understanding that a rectangle contains two pairs of equal sides (length and breadth), and that the distance around the rectangle is equal to the total of these four sides, one may deduce this formula.

Let us suppose the dimensions of the gray triangle as x and y.

The perimeter of rectangle is given as:

P = 2(1 + b)

For the blue triangle we have:

P = 2(72 + 68)

For the gray triangle we have;

P = 2(x + y)

Equating the two since they are equal we have:

2(72 + 68) = 2(x + y)

280 = x + y

We also know the area of the gray triangle thus:

xy = 3876

Substituting y = 280 - x into the second equation, we get:

x(280 - x) = 3876

x² - 280x + 3876 = 0

x = (280 ± √(280² - 4(1)(3876))) / 2

x ≈ 62.7 or x ≈ 61.9

We may discard the negative answer since a rectangle's dimensions cannot be negative.

Substituting the value of x we have:

y = 280 - 61.9 = 218.1 km.

Hence, the dimensions of the gray rectangle are approximately 61.9 km by 218.1 km.

Find the length of the hypotenuse in a right triangle with the following two side lengths.

a = 12, b = 16, c = ?


A. c = 17

B. c = 18

C. c = 19

D. c = 20

Answers

Answer: 20

Step-by-step explanation:

Using the Pythagorean theorem, we know that:

c² = a² + b²

Substituting the given values, we get:

c² = 12² + 16²

c² = 144 + 256

c² = 400

Taking the square root of both sides, we get:

c = √400

c = 20

Therefore, the length of the hypotenuse in the right triangle is 20.

the answer is d which is 20

explanation:
hypotenuse aka c^2 = a^2 + b^2
c^2 = (12x12)+(16x16) = (144) + (256)
c^2 = 400
*square root both sides to remove the square in c*
c = 20
