Answer:

C

Step-by-step explanation:

Don't worry about the volume to start with. Just look at the area of the top or bottom.

The hole has a 4 inch diameter

d = 4

r = d/2

r = 2

Area = pi r^2

Area = pi * 2^2

Area = 4 pi

Now find the area of the top (or bottom) if the circle was not there.

L = 8

W = 6

Area = L * W

Area = 8 * 6

Area = 48

Now take away the area of the circle.

Area Top = 48 - 4 * pi

Area Top = 48 - 12.56

Area Top = 35.44

Finally, Find the volume

Volume = area of the top * height

Volume = 35.44 * 15

Volume = 531.6

Answer:

Reflections, rotations, and translations

Step-by-step explanation:

Given a 20 question true/false test, the probability of getting at least 12 correct is 0.25. Therefore, the correct option is option 4.

To find the probability of getting at least 12 correct answers on a 20-question true/false test, we'll use the binomial distribution formula and the given answer choices.

The binomial probability formula is P(X=k) = C(n,k) * p^k * (1-p)^(n-k), where:

P(X=k) is the probability of getting k successes (correct answers)

C(n,k) is the number of combinations (n choose k)

n is the number of trials (questions)

k is the number of successes (correct answers)

p is the probability of success (0.5 for true/false questions)

To find the probability of getting at least 12 correct, we need to calculate P(X>=12). We can use a calculator or a binomial probability table to find this probability. Using a calculator, we get:

P(X>=12) = 1 - P(X<=11) = 1 - binomdist(11,20,0.5,true) ≈ 0.252

Therefore, the answer is option 4: 0.25, which is the closest choice to our calculated probability.

Answer:

Graph 1. Parallel

Graph 2. Neither

Graph 3. Neither

Graph 4. Perpendicular

Step-by-step explanation:

The rate of change of the radius is -9/(2π*99) inches/second.

The volume of a cylinder can be found with the equation V = πr^2h, where V is the volume, r is the radius, h is the height and π is a constant. We know that the volume is constant at 1318 cubic inches and we know that the height of the cylinder is increasing at a constant rate of 9 inches per second.

V = πr^2h

1318 = π * 99^2 * h

Now we can differentiate this equation with respect to time.

dV/dt = 2πr*dr/dt * h + πr^2 * dh/dt

where dV/dt is the rate of change of the volume, dr/dt is the rate of change of the radius and dh/dt is the rate of change of the height.

Now we know that dV/dt = 0, dh/dt = 9 and we know the value of r, we can substitute these values in the above equation and solve for dr/dt

0 = 2π * 99 * dr/dt * h + π * 99^2 * 9

dr/dt = -9/(2π*99) inches/second

The rate of change of the radius is -9/(2π*99) inches/second at the instant when the radius of the cylinder is 99 inches.

The p-value for the hypothesis test that tests if the average response from treatments A and B is greater than the average response from the remaining treatments is also 0.056.

The p-value for this hypothesis test is 0.056.

Note, this p-value is based on the hypothesis test that is computed by taking the average response of Treatments A and B minus the average response of the remaining treatments.

To find out the p-value for this hypothesis test if the research was interested in testing if the average response from treatments A and B is greater than the average response from the remaining treatments,

we need to consider the following hypotheses:

Null Hypothesis: H0: μ1 ≤ μ2 (The null hypothesis is that the average response of treatments A and B is less than or equal to the average response of the remaining treatments)

Alternative Hypothesis: Ha: μ1 > μ2 (The alternative hypothesis is that the average response of treatments A and B is greater than the average response of the remaining treatments)

We can use the same p-value of 0.056 that was obtained in the previous hypothesis test.

This is because the p-value is a measure of evidence against the null hypothesis.

If we reject the null hypothesis for the first hypothesis test (at a significance level of α),

we would also reject the null hypothesis for the second hypothesis test at the same significance level (α).

Thus, the p-value for the hypothesis test that tests if the average response from treatments A and B is greater than the average response from the remaining treatments is also 0.056.

Step-by-step explanation:(4/100x)+(6/100y)=178---------(i)

2х+3y=8900-----------(i)

x+y=3600---------(ii)

where x is phone

y is pen

The system of equations that describes the situation are 4x + 6y = 17800 and x + y = 3600.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Let the cost of 1 phone is x dollars and cost of 1 computer is y dollars.

Cameron earns a 4% commission on the total dollar amount of all phone sales he makes and earns a 6% commission on all computer sales.

∴ (4/100)x + (6/100)y = 178

4x + 6y = 17800...(i)

Cameron made a total of $3600 in sales.

∴ x + y = 3600...(ii)

Now to solve the equations we'll multiply eqn(ii) by 4 or 6 to cancel out x or y, and then we'll substitute the numerical value of x or y in any of these equations.

3.31 it will take her to complete the triathlon.

To find this, we can apply the equation distance = rate x time.

We are aware of the length and pace of each triathlon leg. Let's name them, respectively, d and r. We must locate the time, which we shall designate as t.

d = r x t    or

t = d/r

The distance is 0.93, or 93/100, and the rate is 1.2, or 12/10 when swimming. As a result of our formula, we have:

12/10 divided by 93/100 yields the same result as

93/100 * 10/12

time to swim = 93/120 = 31/40

We have a distance of 24.8 miles, or 248/10, and a speed of 18.8 miles, or 188/10, for biking. Using the same formula, we obtain:

248/10 divided by 188/10 or

248/10 * 10/188 = 248/188 = 62/47 = time to bike

Finally, for the run, the distance is 6.2 = 62/10 and the rate is 5.1 or 51/10. Plugging this into the formula gives:

62/10 divided by 51/10 or

62/10 * 10/51 = 62/51 = time to run

= 31/40 + 62/47 + 62/51

Step-by-step explanation:

Based on the given inequality of y≥ x - 1, the graph that matches it best is C. Graph A.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

We know that how are inequalities graphed:

When graphing an inequality with the "greater or equal" and "less or equal" signs, the line will be a steady line as shown by graphs A and B.

If y is the larger or equal variable, the shaded area will be to the left of the line.

The inequality is y≥ x - 1 which means that the line should be steady and the shading should be on the left of the line.

Answer:

The answer is 94.5

Step-by-step:

This is actually quite simple. Although, in order to do this you will need a calculator. First, you identify which trigonomic function you will use in order to find the value of x. for this problem you need to use the COS function. The equation for this is COS67= 67/x. Because you are trying to find x you would multiply each side by x. now the equation is xCOS67= 67. because you still can't find the value of x by doing this you will need to get x by itself. To get x by itself divide each side by COS67. the equation is now x= 94/ COS67. This is where the calculator comes in. On the calculator enter 94 divided by 67 then COS function. This gives you the measure of RS.

The game of matching pennies has a mixed strategy Nash equilibriumIn the game of matching pennies, there are two players, Player 1 and Player 2.

Each player can choose to either show heads (H) or tails (T) by flipping a penny. The payoff matrix for the game is as follows:

       Player 2

        H    T

Player 1

H       1   -1

T      -1    1

A Nash equilibrium is a strategy profile where no player can unilaterally change their strategy to obtain a higher payoff.

In the game of matching pennies, if Player 1 chooses heads, Player 2 would want to choose tails to maximize their payoff. Similarly, if Player 1 chooses tails, Player 2 would want to choose heads. This implies that Player 2 can't have a pure strategy Nash equilibrium since they would have an incentive to switch their strategy based on Player 1's choice.

However, in the game of matching pennies, there exists a mixed strategy Nash equilibrium. Both players can choose their strategies randomly with equal probabilities. For example, Player 1 can choose heads with a probability of 0.5 and tails with a probability of 0.5, while Player 2 can choose heads with a probability of 0.5 and tails with a probability of 0.5.

In this case, neither player has an incentive to change their strategy since the expected payoffs are the same regardless of the opponent's strategy. Thus, the mixed strategy Nash equilibrium is achieved when both players randomize their choices equally.

Therefore, the game of matching pennies has a mixed strategy Nash equilibrium.

The probability that X is greater than 145.28 is approximately 0.0465.

Given that X is normally distributed with mean (μ) of 110 and standard deviation (σ) of 21. We are to find the probability that X is greater than 145.28. It can be calculated as follows: We can calculate the Z-score value with the help of the following formula, Z = (X - μ) / σWhere X is the random variable value, μ is the mean, and σ is the standard deviation. Substituting the values in the formula, we get: Z = (145.28 - 110) / 21Z = 1.68476 Using the Z-table, we can find the probability that X is greater than 145.28 as follows: From the Z-table, we get: P(Z > 1.68) = 0.0465

The probability that two out of three sets will go to tiebreakers ≈ 0.061

To calculate the probability that two out of three sets will go to tiebreakers, we need to consider the possible combinations of sets that can have tiebreakers.

There are three possible scenarios where two sets out of three can have tiebreakers:

1. The first two sets go to tiebreakers, and the third set does not.

2. The first and third sets go to tiebreakers, and the second set does not.

3. The second and third sets go to tiebreakers, and the first set does not.

The probability of each scenario occurring can be calculated by multiplying the probability of a tiebreaker (0.14) by the probability of not having a tiebreaker (1 - 0.14 = 0.86) for the remaining set.

1. Probability of scenario 1: (0.14) * (0.14) * (0.86) = 0.020408

2. Probability of scenario 2: (0.14) * (0.86) * (0.14) = 0.020408

3. Probability of scenario 3: (0.86) * (0.14) * (0.14) = 0.020408

To find the probability that any of these scenarios occur, we sum up the probabilities of the three scenarios:

Total probability = 0.020408 + 0.020408 + 0.020408 = 0.061224
