The formula for the surface area of the box, in terms of the length of one side of the square base (s), is A = s^2 + 4s^2 = 5s^2.

The derivative of the surface area function with respect to s, denoted as dA/ds, gives us the rate of change of the surface area with respect to the length of one side of the base.

1. The surface area of the box consists of the area of the square base and the four equal sides. The area of the square base is s^2, and each side has a length of s. Therefore, the total surface area is given by A = s^2 + 4s^2 = 5s^2.

2. To find the derivative of the surface area function, we differentiate 5s^2 with respect to s using the power rule of differentiation. The power rule states that if we have a function f(x) = cx^n, then the derivative is f'(x) = cnx^(n-1).

  Applying the power rule, we have dA/ds = d(5s^2)/ds = 10s.

3. The derivative, dA/ds = 10s, represents the rate of change of the surface area with respect to the length of one side of the square base. This means that for every unit increase in s, the surface area increases by 10s units.

  The derivative does not provide information about minimizing the amount of material used. To find the dimensions of the box that minimize the amount of material used, we need to set up an optimization problem and solve for the critical points. This involves setting the derivative equal to zero and finding the values of s that satisfy this equation. However, since the problem statement does not provide a specific volume constraint or objective function, we cannot proceed with the optimization process.

We are given a function y = -4x^3 - 9x^11, and we need to find its first and second derivatives.

To find the first derivative, we apply the power rule and the constant multiple rule. The power rule states that the derivative of x^n is nx^(n-1), and the constant multiple rule states that the derivative of kf(x) is k*f'(x), where k is a constant. Applying these rules, we can find the first derivative of y = -4x^3 - 9x^11.

Taking the derivative term by term, the first derivative of -4x^3 is -43x^(3-1) = -12x^2, and the first derivative of -9x^11 is -911x^(11-1) = -99x^10. So, the first derivative of y is dy/dx = -12x^2 - 99x^10.

To find the second derivative, we apply the same rules to the first derivative. Taking the derivative of -12x^2, we get -122x^(2-1) = -24x, and the derivative of -99x^10 is -9910x^(10-1) = -990x^9. Therefore, the second derivative of y is d^2y/dx^2 = -24x - 990x^9.

The speed of the object is 12121 m per week.

What does it mean to do speed?

The object is moving at a speed of 2 centimeters every 7 seconds.

We need to find the speed in m per week.

2 cm = 0.02 m

1 week = 604800 s

7 s =  \(1.65 * 10^{-6} week\)

Speed = distance/time

So,

\(v = \frac{0.02 m}{1.65 * 10^{-6 } week}\)

\(v = 12121.21 m/ week\)

or v = 12121 m/ week

So, the speed of the object is 12121 m per week.

The probability that all four numbers generated by the computer program are greater than 10 is 1/16. This is obtained by multiplying the individual probabilities of each number being greater than 10, which is 1/2. The probability of randomly selecting four balls, one at a time, from a bag containing 20 balls numbered 1 to 20, and having all four of them be numbers greater than 10 is 168/517.

a) For each number generated by the computer program, the probability of it being greater than 10 is 10/20 = 1/2, since there are 10 numbers out of the total 20 that are greater than 10. Since the numbers are generated independently, the probability of all four numbers being greater than 10 is (1/2)^4 = 1/16.

b) When taking out the balls from the bag, the probability of the first ball being greater than 10 is 10/20 = 1/2. After removing one ball, there are 19 balls left in the bag, and the probability of the second ball being greater than 10 is 9/19.

Similarly, the probability of the third ball being greater than 10 is 8/18, and the probability of the fourth ball being greater than 10 is 7/17. Since the events are dependent, we multiply the probabilities together: (1/2) * (9/19) * (8/18) * (7/17) = 168/517.

Note: The probability in part b) assumes sampling without replacement, meaning once a ball is selected, it is not put back into the bag before the next selection.

The given statement, "Spearman's rank order correlation coefficient may assume a value from -1 to +1" is true.

Spearman's rank-order correlation coefficient is a statistical metric that is used to determine the degree and direction of a link between two variables. The coefficient can have a value ranging from -1 to +1, with -1 being a fully negative correlation, 0 representing no connection, and +1 representing a perfectly positive correlation. A -1 correlation indicates that when one variable grows, the other variable declines, whereas a +1 correlation indicates that as one variable increases, the other variable increases as well.

A correlation value of 0 shows that the two variables have no linear relationship. The coefficient is calculated by ranking the values of each variable and then calculating the differences between the ranks for each observation, and then applying a formula to calculate the coefficient.

The solutions to the inequality -3x > 18 indicate that x is any value less than -6.

The solutions to the inequality -3 > 18 are different from the solutions to -3x > 18. The first inequality states that -3 is greater than 18, which is not true and therefore has no solutions.

On the other hand, the second inequality -3x > 18 can be solved by dividing both sides by -3 (since dividing by a negative number changes the direction of the inequality), resulting in x < -6. Thus, the solutions to the second inequality indicate that x is any value less than -6.

In the inequality -3 > 18, we are comparing the values of -3 and 18. However, -3 is not greater than 18; in fact, it is smaller. Therefore, there are no values of x that satisfy this inequality, and it has no solutions.

On the other hand, in the inequality -3x > 18, we have an inequality involving a variable x. To solve this inequality, we need to isolate x. We divide both sides of the inequality by -3, but since we are dividing by a negative number, the direction of the inequality changes:

-3x > 18

x < -6

Answer:

1. Josie needs 21 litres of fruit juice need 28 litres of lemonade.

2. Josie can make an extra of 35 litres of punch.

3. 5:8

Step-by-step explanation:

a) The ratio of the fruit juice to lemonade = 3:4

Total litres of punch to be made = 49

Amount of fruit juice needed = \(\frac{3}{7}\) x 49

                                                 = 21 litres

Amount of lemonade needed = \(\frac{4}{7}\) x 49

                                                  = 28 litres

Thus, she would need 21 litres of fruit juice need 28 litres of lemonade.

b) She has 15 litres of fruit juice left. Let the litres of punch to be made be represented by s.

\(\frac{3}{7}\) x s = 15

s = 35

Josie can make an extra of 35 litres of punch.

c) For the second batch, she needs;

15 litres of fruit juice needs 20 litres of lemonade.

But adding 4 more litres to the lemonade makes the total litres of lemonade to be 24.

Thus the ratio of the juice to lemonade = 15:24

The mean number of garage stalls per home in the sample of 200 homes is 1.09.

The mean is a measure of central tendency in statistics that represents the average value of a set of numerical data. It is calculated by summing up all the values and dividing by the total number of values.

According to the given information:

To find the mean number of garage stalls per home in the sample of 200 homes, we need to calculate the expected value or the average value of X, which is the number of garage stalls per home. We are given the probabilities of X taking the values 0, 1, and 2, which are P(X=0) = 0.06, P(X=1) = 0.45, and P(X=2) = 0.32.

The formula for calculating the expected value of X is:

E(X) = Σ [ x × P(X=x) ]

where Σ represents the sum of all values of x, and P(X=x) is the probability of X taking the value x.

Using this formula, we can calculate the expected value of X as follows:

\(E(X) = (0 * 0.06) + (1 * 0.45) + (2 * 0.32)\)

\(= 0 + 0.45 + 0.64\)

= 1.09

The unit circle can be divided into 6 equal arcs using t-values that are multiples of π/3.

To determine the number of equal arcs that can be formed by dividing the unit circle using t-values that are multiples of π/3, we need to consider the angular measure between each division point.

A circle has a total angular measure of 360 degrees or 2π radians. Since we are using t-values that are multiples of π/3, each division point will have an angular measure of π/3.

To find the number of equal arcs, we divide the total angular measure of the circle (2π radians) by the angular measure between each division point (π/3 radians):

Number of equal arcs = (Total angular measure of the circle) / (Angular measure between each division point)

Number of equal arcs = (2π radians) / (π/3 radians)

Simplifying the expression, we get:

Number of equal arcs = (2π radians) * (3/π radians)

Number of equal arcs = 6

Therefore, the unit circle can be divided into 6 equal arcs using t-values that are multiples of π/3. Each arc will have an angular measure of π/3.
