The volume of a rectangular prism can be written as 168 cubic in

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

WE are given the dimensions as;

length= 8 in

Width = 1 3/4 = 7/4

Height = 12 1/8 = 96/8 in

Thus, the volume of a rectangular prism can be written as:

8 x 7/4 x 96/8

= 168 cubic in

The data on grades (of a particular class) collected over two semesters would be considered as time series data.

Time series data refers to any set of data collected over time, where time acts as a variable in the data set. Time series data consists of repeated measurements of the same variable taken over regular intervals of time.

A time series is a collection of observations obtained by observing a single variable or a single data point over a certain period of time. Time series data are ordered sequentially and collected at evenly spaced intervals of time. In this question, the grades were collected over two semesters, which are considered a series of two data points that were collected over time. Hence, it is a time series data.

The data on grades (of a particular class) collected over two semesters would be considered time series data whereas Cross-sectional data is a type of data that is collected at a particular point in time.

The data on grades (of a particular class) collected over two semesters would be considered time series data. This is because time series data is collected over time at regular intervals, and in this case, the data is collected over two semesters, which are specific periods of time.

Time series data is a type of data that is collected over time at regular intervals. This type of data is commonly used in various fields such as economics, finance, and statistics. Time series data is useful in identifying trends, seasonal patterns, and cycles within the data. It can also be used to predict future values based on the patterns that are observed within the data.

Cross-sectional data is a type of data that is collected at a particular point in time. This type of data is commonly used in surveys and opinion polls. Cross-sectional data is useful in identifying the characteristics of a particular group of people or entities at a particular point in time. It is also used to compare the characteristics of different groups of people or entities at the same point in time.

No, neither fog nor gof is equal to x. The expressions fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5 have different constant terms, indicating that they are not equal to x. The correct option is O (No, no.)

To determine whether the composite functions, fog and gof, are equal to x, we need to evaluate them using the functions f(x) = 1/5x and g(x) = 2x - 5.

First, let's calculate fog:

fog(x) = f(g(x)) = f(2x - 5) = 1/5(2x - 5) = 2/5x - 1

Next, let's calculate gof:

gof(x) = g(f(x)) = g(1/5x) = 2(1/5x) - 5 = 2/5x - 5

Comparing fog and gof, we can see that they are not equal to x. Specifically, fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5.

Therefore, the correct option is "No, no" as neither fog nor gof is equal to x.

Alternatively, if we simplify fog and gof as a single expression, we have fog(x) = 2/5x - 1 and gof(x) = 2/5x - 5. Since both expressions have different constant terms, they cannot be equal to x.

Step-by-step explanation:

Arc length is basically circumference.

Then we are going to multiply by pi.

Arc length = 30π OR 94.2

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.

To find probability we can use the properties of the normal distribution.

Given,

Mean (μ) = $958

Standard deviation (σ) = $144

Sample size (n) = 99

We want to find the probability P(934.8 < X < 965.2).  X represents the mean value of a randomly selected policy.

Calculate z-score for the lower value.

z1 = (934.8 - μ) / (σ / sqrt(n))

Calculate z-score for the upper value.

z2 = (965.2 - μ) / (σ / sqrt(n))

Cumulative probability between the z-scores.

P(934.8 < X < 965.2) = P(z1 < Z < z2)

If P(Z < z1) = 0.2658. P(Z < z2) = 0.8477. The probability of interest would be.

P(934.8 < X < 965.2) = P(z1 < Z < z2) = P(Z < z2) - P(Z < z1) = 0.8477 - 0.2658 = 0.5819

Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.

Answer:What is the symbol at the end?

Step-by-step explanation:

Answer:

25.7 m

Step-by-step explanation:

The formula for the circumference of a circle is C = 2(pi)(r), where r is the radius, which in turn is half the diameter.  Thus, the formula for the circumference is C = (d)(pi).  The perimeter of a semicircle is half that, or

C = (pi)(r), which here is (3.14)(5 m) = 15.7 m.  Finally, the total perimeter is the sum of this 15.7 m and the 10 m diameter of the circle:

P = 15.7 m + 10 m = 25.7 m
