The sampling method used by the principal is Stratified sampling.

What is Stratified sampling?

Stratified sampling is a sampling method where the population is divided into non-overlapping subgroups, called strata, based on certain characteristics or attributes, and then a random sample is drawn from each stratum.

In this case, the principal organized the school's population by grade level, which created four strata: freshman, sophomore, junior, and senior classes. The principal then randomly sampled fifty students from each of these four strata to collect data on their preferred elective course. This approach ensures that each grade level is represented in the sample, which can provide a more accurate and representative picture of the preferences of students in each grade level, compared to other sampling methods.

Feng went shopping for a new pair of pants because of a sale. The store was offering a 40% discount. If the price on the tag was $33, what would be the price after the discount but before tax, to the nearest dollar and cent?

Answers

We need to know about percentage to solve the problem. The price of the pair of pants after discount but before tax is $19.8

Percentage of a number gives us a certain part of the quantity, suppose we say that 20% of 100 then we have 20. It can be defined as a given part in every hundred. In this question we know that the store Feng goes to buy a pair of pants offers 40% discount, which means that Feng can save 40% of the price of the pants. The original price on tag is given as $33, we have to find what 40% of $33 is and then subtract that amount from $33 to get the price of the pair of pants after discount but before tax.

Discount=\(\frac{40}{100}\)x33=132/10=13.2

The price of the pants after discount =$(33-13.2)=$19.8

Therefore we found that the price of the pair of pants after discount but before tax is $19.8

Answers

Here, limit as x approaches infinity of a sub n over b sub n equals 3.14159. The statement that is true is a converges by the limit comparison test if b_n converges. What is the limit comparison test? The limit comparison test is a convergence or divergence test for a positive series of numbers that can be compared to another series of numbers.

It states that if a_n and b_n are two positive terms in a series, and if lim (n→∞) a_n / b_n = c, where c is a positive constant, then the two series converge or diverge together. The statement a converges by the limit comparison test if bn converges is true, as if a_n/b_n = 3.14159, and if b_n is converging, then a_n also converges. Hence, the limit comparison test tells us that if b_n converges, then an also converges. Therefore, we can say that the given statement is true. So, the correct option is a_n converges by the limit comparison test if b_n converges.

The base of a glass paperweight is a regular hexagon with a side length of
6 centimeters. the area of the base is 93.6 square centimeters. the slant height is 12 centimeters. what is the surface area of the paperweight?

Answers

Answer:

The surface area of a solid object like a paperweight is calculated by adding the areas of all its faces. In this case, the paperweight is like a hexagonal pyramid, with a hexagonal base and six triangular sides. The base area has already been given as 93.6 square centimeters.

The six triangles are isosceles triangles, since the base of each triangle is a side of the hexagon, and the slant height is the same for each triangle.

The area of an isosceles triangle is given by the formula:

Area = 1/2 * base * height

For these triangles, the base is 6 cm (side length of the hexagon), and the height is the slant height, which is 12 cm.

So the area of one triangle is:

Area = 1/2 * 6 cm * 12 cm = 36 square cm

Since there are six such triangles, the total area of the triangular faces is:

6 * 36 square cm = 216 square cm

So, the total surface area of the paperweight is the area of the base plus the area of the six triangular faces, or:

93.6 square cm (base) + 216 square cm (sides) = 309.6 square cm

So the surface area of the paperweight is 309.6 square cm.

A scientist studying growth of corn plants finds that the average height of her plants increases from 14 1/2 in. to 20 3/10 in. during a one-week period. To the nearest whole percent, what is the percent increase in the average height of the corn plants during this period?

Answers

The initial height of the corn plants is 14 1/2 in. and the final height is 20 3/10 in. The difference between these two heights is:

20 3/10 in. - 14 1/2 in. = 5 8/10 in. = 58/10 in.

To find the percent increase, we need to divide the difference by the initial height, and then multiply by 100 to express the answer as a percentage:

percent increase = (difference / initial height) x 100%

percent increase = (58/10 in. / (29/2) in.) x 100%

percent increase = 2 x 100% = 200%

Therefore, the percent increase in the average height of the corn plants during this period is 200%, to the nearest whole percent.

Suppose a family has saved enough for a 10 day vacation (the only one they will be able to take for 10 years) and has a utility function U = V1/2 (where V is the number of healthy vacation days they experience). Suppose they are not a particularly healthy family and the probability that someone will have a vacation-ruining illness (V = 0) is 20%. What is the expected value of V?
Select one:
a. 10
b. 8
c. 2
d. 0

Answers

Answer: The expected value of V can be calculated as the sum of the products of the possible values of V and their corresponding probabilities. Let's consider the three possible scenarios:

V = 0 (with probability 0.2, as given in the problem)

V > 0 but V < 10 (with probability 0.8 * (9/10), because if nobody gets sick, they will have at least 1 healthy vacation day, and if they have 1 healthy day, they can still have 9 more days of vacation)

V = 10 (with probability 0.8 * (1/10), because if nobody gets sick, they can have all 10 days of vacation)

Using the utility function, we can see that the expected value of V is:

E[V] = 0 * 0.2 + (1/2) * (0.8 * 9/10) + 10 * (0.8 * 1/10)

E[V] = 0 + 0.36 + 0.8

E[V] = 1.16

Therefore, the expected value of V is 1.16. However, since V represents the number of healthy vacation days, it must be a non-negative integer. So, the closest integer to 1.16 is 1. Therefore, the answer is c. 2.

Find the volume of the largest rectangular box in the first octant with three faces in the coordinate planes, and one vertex in the plane.

Answers

The volume of the largest rectangular box in the first octant with three faces in the coordinate planes, and one vertex in the plane is V = xyz, where x, y, and z are the lengths of the sides of the rectangular box.

To find the largest volume, we need to maximize x, y, and z. Since we have three faces in the coordinate planes, one vertex will be at the origin (0, 0, 0). The other two vertices will lie on the coordinate axes.

Let's assume the vertex on the x-axis is (x, 0, 0), and the vertex on the y-axis is (0, y, 0). The third vertex on the z-axis will be (0, 0, z). Since the box is in the first octant, all the coordinates must be positive.

To maximize the volume, we need to find the maximum values for x, y, and z within the constraints. The maximum values occur when the box touches the coordinate planes. Therefore, the maximum values are x = y = z.

Substituting these values into the volume formula, we get V = xyz = x³. Therefore, the volume of the largest rectangular box is V = x³.

Find all values of x (if any) where the tangent line to the graph of the function is horizontal:y= x^2+2x-3A)1/2B0C1D-1

Answers

The correct answer is D) -1.

To find the values of x where the tangent line to the graph of the function \(y = x^2 + 2x - 3\)is horizontal, we need to find the points where the derivative of the function is equal to zero.

First, let's find the derivative of the function:

\(y = x^2 + 2x - 3\)i

y' = 2x + 2

Setting y' equal to zero and solving for x:

2x + 2 = 0

2x = -2

x = -1
