a) B is a subset of A, b) C is not a subset of A, c) C is a subset of C, and d) C is a proper subset of A.

(a) To determine whether B is a subset of A, we need to check if every element in B is also present in A. In this case, B = {a, b, f} and A = {a, b, c, d}. Since all the elements of B (a, b) are also present in A, we can conclude that B is a subset of A. Thus, B ⊆ A.

(b) Similar to the previous question, we need to check if every element in C is also present in A to determine if C is a subset of A. In this case, C = {b, d} and A = {a, b, c, d}. Since both b and d are present in A, we can conclude that C is a subset of A. Thus, C ⊆ A.

(c) When we consider C ⊆ C, we are checking if every element in C is also present in C itself. Since C = {b, d}, and both b and d are elements of C, we can say that C is a subset of itself. Thus, C ⊆ C.

(d) A proper subset is a subset that is not equal to the original set. In this case, C = {b, d} and A = {a, b, c, d}. Since C is a subset of A (as established in part (b)), but C is not equal to A, we can conclude that C is a proper subset of A. Thus, C is a proper subset of A.

Answer:

The convenience store has a markup amount of $30 on the pre-paid mobile phones and the retail price is $42

Step-by-step explanation:

The purchase price of the pre-paid mobile phones is $12.

The convenience store uses a markup rate of 250%.

The markup amount is:

250 * 12 / 100 = 30

The retail price is the purchase price plus the markup amount:

Retail price = $12 + $30 = $42

The convenience store has a markup amount of $30 on the pre-paid mobile phones and the retail price is $42

The forecast for May using a five-month moving average is 39 (Option E).

Moving average is used for smoothing out time series data to find any trends or cycles within the data. A five-month moving average is the average of the past five months. To calculate the moving average, add up the sales for the previous five months and divide it by five.

According to the question, the sales for the previous five months are: Nov. 39 Dec. 27 Jan. 40 Feb. 42 Mar. 41 April 47

We have to add the sales of these five months, which gives:

27 + 40 + 42 + 41 + 47 = 197

To find the moving average for May, we divide this sum by 5:

197 / 5 = 39.4

Since we have to round the answer to the nearest whole number, we round 39.4 to 39, which is option E.

A) In this scenario, it is impossible to determine who the murderer was.

B) In this scenario, it is possible to determine who the murderer was.

Smith's statement suggests that Jones is the killer, while Williams's statement suggests that either Smith or Jones is the killer. However, since the guilty man's statement may or may not be true, it is impossible to ascertain which of the three men is the guilty party.

Since the two innocent men are telling the truth, Smith's statement implies that Jones is the killer, and Williams's statement implies that either Smith or Jones is the killer.

Therefore, either Smith or Jones is the murderer. To comment on someone else's topic, the guilty party must be the one who had a motive. It is impossible to know the motive without more information, so the answer must be based on the statements from Smith, Jones, and Williams. In conclusion, based on the statements given, either Smith or Jones is the murderer.

Step-by-step explanation:

The value of the standard deviation of the variance S is equivalent to 250 and the value of the variance (S) is equivalent to 62500.

Given that:

2Ax = 0.08

Ax = 0.2

A fully discrete whole life insurance issued to (x) is 1000.

Firstly we have to find out the value of variance S.

Variance S = (insurance issued)^2 * [2Ax - Ax^2]/(1- Ax)^2

Variance S = (1000)^2 * [0.08 -  0.2^2]/(1- 0.2)^2

Variance S = (1000)^2 * [0.04]/.64

Variance S = (1000)^2 * .0625

Variance S = 62500

Standard deviation of S = (insurance issued) * [\(\sqrt{2Ax - Ax^2}\)]/(1- Ax)

Standard deviation = 1000 * [\(\sqrt{0.08 - 0.2^2}\)]/(1- 0.2)

Standard deviation = 1000 * 0.2/0.8

Standard deviation = 1000 * 1/4 = 250

The value of the standard deviation of the variance S is equivalent to 250 and the value of the variance (S) is equivalent to 62500.

The expected value in a binomial situation with n = 18 and π = 0.60 is E(X) = np = 18 * 0.60 = 10.8.

In a binomial situation, the expected value, denoted as E(X), represents the average or mean outcome of a random variable X. It is calculated by multiplying the number of trials, denoted as n, by the probability of success for each trial, denoted as π.

In this case, we are given n = 18 and π = 0.60. To find the expected value, we multiply the number of trials, 18, by the probability of success, 0.60.

n = 18 (number of trials)

π = 0.60 (probability of success for each trial)

To find the expected value:

E(X) = np

Substitute the given values:

E(X) = 18 * 0.60

Calculate the expected value:

E(X) = 10.8

Step-by-step explanation:

There are 3003 ways to distribute the 15 pieces of candy to 5 children, regardless of the order in which the children receive the candy.

The concept of combinations is used to find the number of ways to choose a certain number of items from a larger set of items, without regard to their order. In this case, the larger set of items is the 15 pieces of candy (8 strawberry and 7 rhubarb), and we want to find the number of ways to choose 5 pieces of candy to give to 5 children.

The formula for combinations is C(n, k) = n! / (k! * (n-k)!), where n is the total number of items, k is the number of items to choose, and ! means factorial. Factorial of a number n is the product of all positive integers up to n, so for example, 5! = 5 * 4 * 3 * 2 * 1 = 120.

So, using this formula, we can calculate the number of combinations of 15 items taken 5 at a time:

C(15,5) = 15! / (5! * (15-5)!) = 15! / (5! * 10!) = 15 * 14 * 13 * 12 * 11 / (5 * 4 * 3 * 2 * 1) = 3003.

So there are 3003 ways to distribute the 15 pieces of candy to 5 children, regardless of the order in which the children receive the candy.

Step-by-step explanation:

Coordinates in two dimensions are given as an ordered pair, (x, y). That is, the x-coordinate is always listed first, followed by the y-coordinate.

The x-coordinate is the distance to the right of the x=0 point, or y-axis. Distances to the left have a negative sign. Here, the given point is 5 grid squares to the left of the y-axis, so has an x-coordinate of -5/4 = -1 1/4. (Each grid square on this graph is 1/4 unit.)

The y-coordinate is the distance above the y=0 point, or x-axis. Distances below have a negative sign. Here, the given point is 3 grid squares above the x-axis, so has a y-coordinate of 3/4.

The coordinates of the given point are (x, y) = (-1 1/4, 3/4).

Additional comment

The above discussion refers to coordinates on the "Cartesian plane." There are other ways of determining location. Some are based on the distance from an origin and an angle from a reference direction. Then, the ordered pair is not (distance right, distance up), but may be (distance from origin, CCW angle from 'right'). In navigation, it may be (latitude angle, longitude angle), or (bearing distance, bearing angle CW from North).

Using the formula, we have:

T(8) = T0 + r(8)

= 65 + 25(8)

= 265°

Hence, the oven has a 265° temperature 8 minutes after being turned on.

Simply enter the value of t into the formula to determine the oven's temperature after any duration t:

T(t) = T0 + rt

= 65 + 25t

Hence, the oven's temperature after t minutes is 65 + 25t degrees.

A temperature is a number that is used to quantify how hot or cold a specific location, object, etc. is.

The average kinetic energy of a system is measured by its temperature.

The kinetic energy of a system starts to rise as the particle's velocity increases, which raises the system's temperature. The energy that is transferred when two bodies with different surface temperatures come in touch is referred to as heat. Absolute Zero is the lowest temperature that can be reached before further energy removal is impossible. Temperature measurement is the primary function of thermometers. Several scales are used by thermometers to measure temperatures. The Celsius (C) scale is a widely used scale. The Kelvin (K) and Fahrenheit scales are additional temperature measurement units (F)

Reason:

We divide the two mean absolute deviation (MAD) values to get (1.2)/(0.6) = 2.0

The variability in the first set (the 6th graders) is exactly twice that of the variability of the second set (the 7th graders).

The MAD is one measure of variability or spread. Another would be the standard deviation. The larger the value, the more spread out the data points will be.
