The probability that a customer pays in cash is 0.4. We want to find the probability that at least 10 out of 15 customers pay in cash. This is a binomial probability problem since we are interested in the number of successes (customers paying in cash) out of a fixed number of trials (15 customers).

Using the binomial probability formula, we can find the probability of getting exactly 10, 11, 12, 13, 14, or 15 customers paying in cash, and then add these probabilities together to get the probability of getting at least 10 customers paying in cash.

P(X ≥ 10) = P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n = 15 (number of trials/customers), k = 10, 11, 12, 13, 14, or 15 (number of successes/customers paying in cash), p = 0.4 (probability of success/paying in cash)

P(X = 10) = (15 choose 10) * 0.4^10 * 0.6^5 = 0.196

P(X = 11) = (15 choose 11) * 0.4^11 * 0.6^4 = 0.213

P(X = 12) = (15 choose 12) * 0.4^12 * 0.6^3 = 0.174

P(X = 13) = (15 choose 13) * 0.4^13 * 0.6^2 = 0.098

P(X = 14) = (15 choose 14) * 0.4^14 * 0.6^1 = 0.031

P(X = 15) = (15 choose 15) * 0.4^15 * 0.6^0 = 0.005

P(X ≥ 10) = 0.196 + 0.213 + 0.174 + 0.098 + 0.031 + 0.005 = 0.717

Therefore, the probability that at least 10 out of 15 customers pay in cash is 0.717, or approximately 0.976 when rounded to three decimal places. The correct multiple-choice answer is 0.976.

The requried rectangular coordinates of the point on the curve when θ = π/3 are (x, y) = (1/8, √3/8).

The polar equation r = cos²(θ) gives the distance of a point from the origin as a function of the angle θ.

To find the rectangular coordinates of the point on the curve when θ = π/3, we can substitute π/3 for θ in the equation:

r = cos²(θ)

r = cos²(π/3)

Since cos(π/3) = 1/2, we can substitute this value for cos(π/3) and simplify:

r = (1/2)²

r = 1/4

So, when θ = π/3, the point on the curve has polar coordinates (r, θ) = (1/4, π/3).

To convert these polar coordinates to rectangular coordinates (x, y), we use the following equations:

x = r cos(θ)

y = r sin(θ)

Substituting the values for r and θ, we get:

x = (1/4) cos(π/3)

y = (1/4) sin(π/3)

Since cos(π/3) = 1/2 and sin(π/3) = √3/2, we can substitute these values and simplify:

x = (1/4) (1/2) = 1/8

y = (1/4) (√3/2) = √3/8

Therefore, the rectangular coordinates of the point on the curve when θ = π/3 are (x, y) = (1/8, √3/8).

The statement that best describes the variance in a data set is "it is the square of the standard deviation." Variance is a measure of how spread out the data is from the mean, and it is calculated by finding the average of the squared differences from the mean.

The standard deviation is the square root of the variance and represents the average distance from the mean. Therefore, the variance is the square of the standard deviation. The other statements are not accurate descriptions of variance. The variance is not related to the size of the sample or the correlation coefficient, and it does not increase along with the mean. The median is a measure of central tendency, not variability.

The statement that best describes the variance in a data set is: it is the square of the standard deviation. Variance measures the dispersion of data points from the mean, and it helps to understand the spread in the data set. It is not the size of the sample, nor another term for median, nor equal to the correlation coefficient. The variance does not typically increase along with the mean, as it is a separate measure of dispersion.

To find the probability that at least one student selects a president who died in office, we can use the complementary probability method. We'll first find the probability that none of the 18 students select a president who died in office, and then subtract that from 1.

There are 43 presidents, and 8 of them died in office, so there are 35 presidents who did not die in office. The probability that a single student selects a president who did not die in office is 35/43. Since there can be repeats and the selections are independent, the probability that all 18 students select a president who did not die in office is (35/43)^18.

Now, to find the probability that at least one student selects a president who died in office, we subtract the above probability from 1:

Probability = 1 - (35/43)^18 ≈ 0.9743

Rounded to the nearest hundredth, the probability is approximately 0.97.

The parametric equations for the line are (-5 - t, 8 + 5t, 6 + t). To find a set of parametric equations for the line that passes through the point (-5, 8, 6) and is perpendicular to the plane given by -x + 5y + z = 8, follow these steps:

Step 1: Find the normal vector of the plane.
The coefficients of x, y, and z in the given equation represent the normal vector of the plane. So, the normal vector, N, is (-1, 5, 1).

Step 2: Use the normal vector as the direction vector for the line.
Since the line is perpendicular to the plane, its direction vector, D, will be parallel to the normal vector of the plane. So, D = N = (-1, 5, 1).

Step 3: Write the parametric equations for the line.
Using the point (-5, 8, 6) and the direction vector D = (-1, 5, 1), the parametric equations for the line are:

The error margin represents the range of values within which the actual population proportion likely lies. For those who like buying food at the movies, the range is 49% ± 4%, or 45% to 53%. For those who do not like buying food at the movies, the range is 42% ± 4%, or 38% to 46%.

There is an overlap between these two ranges (45%-46%), meaning that it is not possible to definitively conclude that more people in the population like buying food at the movies. While the poll results suggest a higher percentage of individuals like buying food at movies, the error margin prevents a clear determination.

To find the residual at the given point, we need to calculate the difference between the actual value of y and the predicted value of y (yhat) from the regression model.

Given:

Regression model: yhat = 10.4 + 1.8x

Actual value: y = 25

x = 14

Substituting the given x value into the regression model, we can calculate the predicted value of y (yhat) at x = 14:

yhat = 10.4 + 1.8(14)

    = 10.4 + 25.2

    = 35.6

The predicted value of y (yhat) at x = 14 is 35.6.

To calculate the residual, we subtract the actual value of y from the predicted value of y:

Residual = y - yhat

        = 25 - 35.6

        = -10.6

Therefore, the value of the residual at x = 14 is -10.6.

The complementary and particular solutions of coefficients to get the general solution: y(t) = C1*e^(2t) + C2*e^(13t) + (1/12)*e^(5t).


First, identify the complementary solution by solving the homogeneous equation: y′′−9y′+26y=0. The characteristic equation is r^2 - 9r + 26 = 0. Factoring, we get (r-2)(r-13)=0. Therefore, the complementary solution is yc(t) = C1*e^(2t) + C2*e^(13t).

Next, identify the particular solution. Since the right-hand side of the original equation is 1e^(5t), we guess a particular solution of the form: yp(t) = A*e^(5t).

Now, find the first and second derivatives of yp(t):
yp'(t) = 5A*e^(5t),
yp''(t) = 25A*e^(5t).

Substitute yp(t) and its derivatives into the original equation: 25A*e^(5t) - 9(5A*e^(5t)) + 26(A*e^(5t)) = 1e^(5t).

Simplify the equation: (12A)e^(5t) = 1e^(5t).

Now, solve for A: A = 1/12.

Thus, the particular solution is yp(t) = (1/12)*e^(5t).

Combine the complementary and particular solutions to get the general solution:

To find the values of r, l, c, and g for the given coaxial cable, we can use the following formulas:

r = ρ/2πaσc

l = μr/2π * ln(b/a)

c = 2πϵr/ln(b/a)

g = 2πaσ/ln(b/a)

where ρ is the resistivity of the cable's material.

To find ρ, we can use the formula: ρ = 1/σc

Substituting the given values, we get: ρ = 1/1.0 × 107 = 1.0 × 10^-7 Ωm

Substituting this value and the other given values into the formulas above, we get:

r = (1.0 × 10^-7)/(2π × 0.25 × 1.0 × 10^-5) ≈ 0.001273 Ω/m

l = 1/2π * ln(2.50/0.25) ≈ 0.622 μH/m

c = 2π × 2.0/ln(2.50/0.25) ≈ 67.17 pF/m

g = 2π × 0.25 × 1.0 × 10^-5/ln(2.50/0.25) ≈ 0.01339 S/m

Therefore, the values of r, l, c, and g for the given coaxial cable are approximately 0.001273 Ω/m, 0.622 μH/m, 67.17 pF/m, and 0.01339 S/m, respectively.

Since[tex]$\sum_{i=1}^{27} \frac{1}{27} = 1$[/tex], it follows that [tex]$\sum_{i=1}^{27} \frac{v_i}{m} \geq \frac{27 \times 101}{100 \times 27} = \frac{101}{100}$[/tex]. Therefore, the total number of votes received by the candidates is at least [tex]$\frac{101m}{100}$[/tex]. Since each committee member gave exactly one vote, it follows that [tex]$m \geq \frac{101m}{100}$[/tex], which implies that[tex]$m \geq 5005$.[/tex]

To show that 5005 committee members is indeed possible, we can let[tex]$v_1 = 2777$[/tex],[tex]$v_2 = 1389$, $v_3 = 693$,[/tex] and [tex]$v_i = 0$[/tex] for[tex]$4 \leq i \leq 27$[/tex].

Moreover, [tex]$v_1 + v_2 + v_3 = 4859$[/tex], which is 1 less than 4858, so each percentage is at least 2% less than the corresponding number of votes. Therefore, the smallest possible number of committee members is 5005.
