C) F
D) all of the above

Answer:

To get back to sea level, the scientist must now rise a total of 19.2 feet. This is calculated by subtracting the total amount of feet she has descended (37.4 + 8.4 = 45.8 feet) from the total amount of feet she has traveled (37.4 + 19.8 + 8.4 = 65.6 feet). Therefore, 19.2 feet (65.6 - 45.8) must be ascended in order to reach sea level.

The decimal fraction that represents the given fraction is: 0.36.

To convert the figure from the given form to the decimal fraction, you can choose to use the long division format or simply divide it with the common factors. Between, 9 and 25, there is no common factor, so the best method to use here will be long division. Thus, we can proceed as follows:

1. 25 divided by 9

This cannot go so, we put a zero and a decimal point as follows: 0.

Then we add 0 to 90

2. Now, 25 divided by 90 gives 3 remainders 15. We add 3 to the decimal: 0.3

3. 90 minus 75 is 15. we add a 0 to this and divide 150 by 25 to get 6. This is added to the decimal to give a final result of 0.36.

The height of the zip line is 203 feet.

Trigonometric functions are required when the value of an unknown side or internal angle of a right triangle are to be determined. Some of the basic functions are: sine, cosine, tangent etc.

Tangent of an angle is the ration of the opposite side to the angle and the adjacent side.

Tan θ = opposite/ adjacent

To determine the height of the zip line required in the question, we have;

let the height be represented by h,

Tan θ = opposite/ adjacent

Tan 10 = h/ 1150

h = Tan 10 * 1150

  = 0.1763*1150

  = 202.745

h = 202.8 feet

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.[2][3] The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.

We need to find the point where the two lines intersect to determine where Jack and Nolan met.

The following equations are provided:

y = (-1/2)x + 4, as well as y = 3x - 3.

We can solve for x by making the two equations equal:

(-1/2)x + 4 = 3x - 3

Simplifying the problem:

The triangle ABC has a surface area of 17.7 square units. Rounding to the nearest tenth of a square unit,

Heron's Formula can be used to calculate the triangle ABC's area. The equation reads as follows:

A = √[s(s-a)(s-b)(s-c)]

Where s is one-half of the triangle's circumference and a, b, and c are its three sides.

By summing the triangle's sides, we can determine the perimeter:

P = a + b + c

The formula below is used to get the other half of the perimeter.

s = P/2

For the triangle ABC, we have the sides a=3, b=5, and c=4.

Therefore, half of the perimeter is s = 8.

Now, Heron's formula can be used to determine the triangle ABC's surface area:

A = √[s(s-a)(s-b)(s-c)]

= √[8(8-3)(8-5)(8-4)]

= √[8(5)(3)(4)]

= 17.7 square units

Therefore, the triangle ABC has a surface area of 17.7 square units, Rounding to the nearest tenth of a square unit.

The change in profit (ΔP) when the number of units (Δx) increases by 5, based on the given marginal profit function, is -18331.50

To find the change in profit (ΔP) when the number of units (Δx) increases by 5.

we need to evaluate the marginal profit function and multiply it by Δx.

The marginal profit function is given by dP/dx = 12.1(60 - 3x).

We are given the value of x as 121, so we can substitute it into the marginal profit function to find the marginal profit at that point.

dP/dx = 12.1(60 - 3(121))

= 12.1(60 - 363)

= 12.1(-303)

= -3666.3

Now, we can calculate the change in profit (ΔP) by multiplying the marginal profit by Δx, which is 5 in this case.

ΔP = dP/dx×Δx

= -3666.3 × 5

= -18331.5

The required unit of the measure of the mean is given in Dollars. Option A is correct.

Given that:

The distribution of prices for a certain car model is approximately normal with a mean of $21,800 and a standard deviation of $400. A random sample of 4 cars of the model will be selected.

The correct unit of measure for the mean of the sampling distribution of the price of the car is to be determined,

The mean of the values is the ratio of the total sum of values to the number of values.

Since the given data is of price in dollars so the measure of the mean will also be taken in Dollars because the mean is defined as the sum of all the values in a particular unit divided by the total number of different quantities.

Area of the circle?

The area of a circle is the amount of space contained within its circumference. It is determined using the formula A = πr^2, where A is the area, r is the radius of the circle (the distance from the center of the circle to any point on its circumference), and π (pi) is a mathematical constant approximately equal to 3.14159.

The area of the circle is given by:

= πr²

= area, r = radius

One piece of wire is used to form the circumference of the circle. The circumference of the circle is given by:

C = 2πr

C = circumference, r = radius

The other piece of wire is used to form the perimeter of the square. To find the length of this piece, simply subtract C from the total length of the wire, 40m:

40 - 2πr

The perimeter of the square is 4 times the length of one of its sides:

P = 4s

P = perimeter, s = side length

We know the perimeter is the length of the second piece of wire 40 - 2πr:

40 - 2πr = 4s

s = 10-πr/2

The area of the square is given by:

As= s², where s = side length

s = 10-πr/2, so plug in s and solve for As:

As = (10-πr/2)²

Now that we have the areas of the circle and the square, let's add them up to find the total area:

Answer:

The sampling method used is a stratified sampling method

Step-by-step explanation:

sampling is the selection of a predetermined representative subpopulation from a larger population, to estimate the characteristics of the whole population.

Stratified sampling: Here, the total population are divided into subcategories (strata) before sampling is done. The strata are formed based on some common characteristics. In our example, the times of the day (morning, afternoon and evening) has widely varying atmospheric conditions which will add biases to the measurement of air quality. For example, the air in the morning if compared to the afternoon in an industrial area may be purer because of minimal industrial activity, hence effective comparison will be made by stratification.

The x-intercept of the function as an ordered pair is equal to (5, 0).

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" or y-value is equal to zero (0).

In this context, we would replace the y-value with zero (0) by substituting it into the given equation y = ∛x - 5 as follows;

y = ∛x - 5

0 = ∛x - 5

Taking the cube root of both sides of the function, we have the following:

The answer is option D: [4, a, c, e). The complement of a set R contains all the elements of the universal set U that are not in R.

The complement of a set R contains all the elements of the universal set U that are not in R.

Given, U = {1, 2, 4, 5, a, b, c, d, e} and R = {1, 2, 5, b, d}

The complement of a set contains all the elements that are not in the original set. The complement of set R would include all the elements of U that are not in R.

The elements in set R are: {1, 2, 5, b, d}

The complement of set R would be: {4, a, c, e}

The complement of set R, denoted by R', is:

R' = U - R

That is, we remove all the elements of R from U to get R'. So we have:

U = {1, 2, 4, 5, a, b, c, d, e}

R = {1, 2, 5, b, d}

Since the rider starts at a height of 30 ft above the ground and ends up 50 ft above the ground, the total change in height is 50-30=20 ft.

plan b would save you money for international calls of less than 285.7 minutes.

To determine the range of minutes for which plan b would save you money, we need to find the point at which the cost of plan b becomes less than the cost of plan a.

Let's assume x represents the number of minutes.

For plan a, the cost is $25 per month plus 5 cents per minute, which can be expressed as 25 + 0.05x.
For plan b, the cost is $5 per month plus 12 cents per minute, which can be expressed as 5 + 0.12x.

To find the range, we need to solve the inequality 5 + 0.12x < 25 + 0.05x.
Simplifying, we get 0.12x - 0.05x < 25 - 5, which becomes 0.07x < 20.
Dividing both sides by 0.07, we find x < 285.7.

Therefore, plan b would save you money for any range of minutes less than 285.7 minutes.

In conclusion, plan b would save you money for international calls of less than 285.7 minutes.
