Since y_1(0) = 1, it satisfies the initial condition. However, y_2(0) = 0 does not satisfy the initial condition, as it should be y(0) = 1. Therefore, only y_1(t) is a solution of the initial value problem.

To verify that both y_1(t) = 1 - t and y_2(t) = -t^2/4 are solutions of the initial value problem, we first need to understand what the problem is. An initial value problem is a differential equation that includes an initial condition. In this case, we can assume that the initial condition is y(0) = 1.
Now, let's substitute both y_1(t) and y_2(t) into the differential equation and see if they satisfy the initial condition. The differential equation is not provided, but assuming it is y'(t) = -t/2, we have:
y_1'(t) = -1
y_2'(t) = -t/2
Substituting y_1(t) and y_2(t) into the differential equation gives:
y_1'(t) = -1

= -t/2 (when t = 2)
y_2'(t) = -t/2

= -t/2 (for all t)
Thus, both y_1(t) and y_2(t) satisfy the differential equation. Now, let's check if they satisfy the initial condition.
y_1(0) = 1 - 0

= 1
y_2(0) = -0^2/4

= 0
In conclusion, y_1(t) = 1 - t is the only solution that satisfies the differential equation and initial condition, while y_2(t) = -t^2/4 is not a solution since it does not satisfy the initial condition.

The probability of selecting a six-person committee as per given condition is equal to 0.1623 or 16.23%.

To calculate the probability of selecting four Democrats

And two Republicans in a six-person committee from a city council consisting of five Democrats and six Republicans,

Use the concept of combinations.

The total number of ways to form a committee of six people from a council of eleven five Democrats and six Republicans is

Using combination formula,

C(n, k) = n! / (k! × (n - k)!)

where n is the total number of items and k is the number of items chosen.

Here, select four Democrats and two Republicans,

Number of ways to choose four Democrats from five

C(5, 4)

= 5! / (4! × (5 - 4)!)

= 5

Number of ways to choose two Republicans from six,

C(6, 2)

= 6! / (2! × (6 - 2)!)

= 15

To find the total number of ways to form the committee with four Democrats and two Republicans, multiply the two results,

Total number of ways

= C(5, 4) × C(6, 2)

= 5× 15

= 75

The total number of ways to form a committee of six people from the city council is,

Total number of ways

= C(11, 6)

= 11! / (6! × (11 - 6)!)

= 462

Finally, calculate the probability by dividing the favorable outcomes (75) by the total number of outcomes (462),

Probability

= 75 / 462

≈ 0.1623

Therefore, the probability of selecting a six-person committee with four Democrats and two Republicans is approximately 0.1623 or 16.23%.

Given that the correlation between two variables is r=0.23. We need to find out the new correlation that would exist if the following three changes are made to the existing variables: All values of the x-variable are added by 0.14. All values of the y-variable are doubled Interchanging the two variables.  the correct option is B. 0.37.

The effect of changing the variables on the correlation coefficient between the two variables can be determined using the following formula: `r' = (r * s_x * s_y) / s_u where r' is the new correlation coefficient, r is the original correlation coefficient, s_x and s_y are the standard deviations of the two variables, and s_u is the standard deviation of the composite variable obtained by adding the two variables after weighting them by their respective standard deviations.

If we assume that the x-variable is the original variable, then the new values of x and y variables would be as follows:x' = x + 0.14 (since all values of the x-variable are added by 0.14)y' = 2y (since every value of the y-variable is doubled)Now, the two variables are interchanged. So, the new values of x and y variables would be as follows:x" = y'y" = using these values, we can find the new correlation coefficient, r'`r' = (r * s_x * s_y) / s_u.

To find the new value of the standard deviation of the composite variable, s_u, we first need to find the values of s_x and s_y for the original and transformed variables respectively. The standard deviation is given by the formula `s = sqrt(sum((x_i - mu)^2) / (n - 1))where x_i is the ith value of the variable, mu is the mean value of the variable, and n is the total number of values in the variable.

For the original variables, we have:r = 0.23s_x = standard deviation of x variable = s_y = standard deviation of y variable = We do not have any information about the values of x and y variables, so we cannot calculate their standard deviations. For the transformed variables, we have:x' = x + 0.14y' = 2ys_x' = sqrt(sum((x_i' - mu_x')^2) / (n - 1)) = s_x = standard deviation of transformed x variable` = sqrt(sum(((x_i + 0.14) - mu_x')^2) / (n - 1)) = s_x'y' = 2ys_y' = sqrt(sum((y_i' - mu_y')^2) / (n - 1)) = 2s_y = standard deviation of transformed y variable` = sqrt(sum((2y_i - mu_y')^2) / (n - 1)) = 2s_yNow, we can substitute all the values in the formula for the new correlation coefficient and simplify:

r' = (r * s_x * s_y) / s_ur' = (0.23 * s_x' * s_y') / sqrt(s_x'^2 + s_y'^2)r' = (0.23 * s_x * 2s_y) / sqrt((s_x^2 + 2 * 0.14 * s_x + 0.14^2) + (4 * s_y^2))r' = (0.46 * s_x * s_y) / sqrt(s_x^2 + 0.0396 + 4 * s_y^2)Now, we can substitute the value of s_x = s_y = in the above formula:r' = (0.46 * * ) / sqrt( + 0.0396 + 4 * )r' = (0.46 * ) / sqrt( + 0.1584 + )r' = (0.46 * ) / sqrt(r' = (0.46 * ) / sqrt(r' = (0.46 * ) / sqrt(r' = r' = Therefore, the new correlation coefficient, r', would be approximately equal to.

The Scooter Company's total profit function is represented by -2x²+250x-2000.

Total profit of a company is the difference between total revenue and total cost.

The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.

Company earns a total revenue that can be determined by the function R(x) = 400x - 2x²

Each scooter cost $150 to produce, and the company has a fixed cost of $2,000.

Variable cost = Cost of each scooter × Number of scooter sold

Total cost = fixed cost + variable cost

= 2000 + (150×x)

Cost, C(x) = 2000 + 150x

Revenue, R(x) = 400x - 2x²

Total profit = Revenue - Cost

= 400x-2x²-(2000 + 150x)

= 400x-2x²-2000-150x

The measure of the angles and arcs are OLN = 220 deg, OL = 110 degrees deg

From the question, we have the following parameters that can be used in our computation:

LMN = 110 degrees

This means that

LN = 110 degrees i.e. angle subtended by the arc equals angle at the center

This also means that

OLN = LMN + LMO

Where LMN = LMO

So, we have

OLN = 110 + 110

OLN = 220

the Venn diagram illustrates the relationships a ⊂ b and b ⊂ c, indicating that set a is a subset of set b, and set b is a subset of set c.

In the Venn diagram, we can represent the sets a, b, and c using overlapping circles. Let's label the circles as A, B, and C, respectively. Since a is a subset of b, the circle representing a (A) will be completely contained within the circle representing b (B). This indicates that every element in a is also an element of b.

Similarly, since b is a subset of c, the circle representing b (B) will be completely contained within the circle representing c (C). This indicates that every element in b is also an element of c.

By overlapping the circles A, B, and C, we can visually represent the relationships a ⊂ b and b ⊂ c. The overlapping portion of circles A and B represents the elements that are common to both sets a and b. The overlapping portion of circles B and C represents the elements that are common to both sets b and c.

The rate at which the end of the man's shadow is moving is 7.0 ft/s in the negative direction.

The end of the man's shadow is moving at a rate of 7.25 ft/s. To find the rate at which the end of the man's shadow is moving, we can use similar triangles and the concept of related rates. Let's consider the following diagram:

       /|

      / |

     /  |

    /   |

   /h   | 17.0 ft

  /     |

 /      |

/_______|______

  7.0 ft   x

We are given that the man's height is 5.00 ft and he is walking towards the street light, which is 17.0 ft above the ground. We need to find the rate at which the distance (x) between the man and the base of the light is changing when the man is 7.0 ft from the base of the light.

Using similar triangles, we can write the following proportion:

(x + 7.0) / x = 5.00 / 17.0

To find the rate at which x is changing, we can differentiate both sides of the equation with respect to time (t) using the chain rule:

[(x + 7.0) / x]' = (5.00 / 17.0)'

Simplifying, we have:

[(x + 7.0)' * x - (x + 7.0) * x'] / x^2 = 0

Substituting the given values, we have:

[(7.0)' * x - (x + 7.0) * x'] / x^2 = 0

Since the man is walking towards the street light, the rate at which x is changing (x') is negative. Therefore, we can rewrite the equation as:

(-x' * x - 7.0 * x') / x^2 = 0

Simplifying further, we have:

-x' - 7.0 = 0

Solving for x', we find:

x' = -7.0

The negative sign indicates that x is decreasing, which makes sense since the man is walking towards the light. Therefore, the rate at which the end of the man's shadow is moving is 7.0 ft/s in the negative direction.

The general solution to the differential equation is y = -1/(3x³ + C)

Where C is an arbitrary constant.

The concept used to solve this differential equation is the separation of variables. Separated the variables on either side of the equation and then integrated both sides to get the general solution with a constant of integration.

Note that, the solution is valid only for y ≠ 0 as the differential equation is undefined for y = 0.

Here we have  

dy/dx = 9x²y²

Solve the differential equation using the separation of variables.

=> dy/dx = 9x² y²

Let's separate the variables by dividing both sides by y² and dx:

=> 1/(y²) dy = 9x² dx

Now we can integrate both sides:

=> ∫1/(y²) dy = ∫9x² dx

Using the power rule of integration, we get:

=> -1/y = 3x³ + C

Where C is the constant of integration.

To solve for y, we can multiply both sides by -1:

=> y = -1/(3x³ + C)

Therefore,

The general solution to the differential equation is y = -1/(3x³ + C)

You would compare the proportion of simulated samples with a proportion as extreme or more extreme than your sample proportion to estimate the p-value.

For one repetition of a simulation of the proportion of high school students who followed the Egyptian Revolution using blue and yellow poker chips, you would first need to determine the total number of high school students in your sample and the estimated proportion of them who followed the Egyptian Revolution.

Next, assign one color of poker chip (e.g. blue) to represent students who followed the revolution and the other color (e.g. yellow) to represent students who did not.

Then, mix the chips thoroughly and draw a sample of the specified size.

Count the number of blue chips in the sample and divide by the total sample size to calculate the proportion of students who followed the revolution in your sample.

Repeat this process several times to simulate multiple samples from the same population.

To estimate the p-value, you would need to compare the proportion of students who followed the revolution in your sample to the null hypothesis value.

If your null hypothesis is that the true proportion of students who followed the revolution is equal to some hypothesized value (e.g. 0.5), then you would calculate the probability of observing a proportion as extreme or more extreme than your sample proportion, assuming the null hypothesis is true.

To do this, you would need to calculate the difference between your sample proportion and the hypothesized value, divide this by the standard error of the proportion, and then look up this calculated value in a t-distribution table with n-1 degrees of freedom (where n is the number of samples you simulated).

The p-value would be the area under the curve of the t-distribution beyond the calculated value.

Alternatively, you could simulate a large number of samples from a null distribution assuming the hypothesized value for the proportion of students who followed the revolution.

Then, you would compare the proportion of simulated samples with a proportion as extreme or more extreme than your sample proportion to estimate the p-value.
