c) The probability that a sample size of 36 has a sample mean of less than 19 is of: 0.0228 = 2.28%.

d) It would be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 19, as the z-score has an absolute value of 2.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The parameters of this problem are given as follows:

\(\mu = 20, \sigma = 3, n = 36, s = \frac{3}{\sqrt{36}} = 0.5\)

The probability that a sample size of 36 has a sample mean of less than 19 is the p-value of Z when X = 19, hence:

\(Z = \frac{X - \mu}{\sigma}\)

By the Central Limit Theorem

\(Z = \frac{X - \mu}{s}\)

Z = (19 - 20)/0.5

Z = -2

Z = -2 has a p-value of 0.0228.

Suppose x has a distribution with a mean of 20 and a standard deviation of 3. Random samples of size n=36 are drawn.

C. Find P(x<19) (answer should be: 0.0228)

D. Would it be unusual for a random sample of size 36 from the x distribution to have a sample mean less than 19? Explain. (answer should be: Yes, only about 2.3% of all such samples have means less than 19)

The probability that at least 75 rolls are necessary to exceed a total sum of 275 is approximately 0.293.

Let X be the random variable denoting the total number of rolls required to exceed 275. We want to calculate P(X >= 75). The probability of rolling a number greater than 5 is 1/3, and the probability of rolling a number less than or equal to 5 is 2/3. Therefore, the expected value of a single roll is

The variance of a single roll is

Using the properties of the geometric distribution, we can calculate the probability that it takes at least 75 rolls to achieve a sum greater than 275:

P(X >= 75) = (1 - P(X < 75)) = (1 - (1 - (275/3.67)/75\()^{(75)}\)) = 0.293.

Therefore, the probability that at least 75 rolls are required is approximately 0.293.

The fact that PC is less than 50% indicates a higher probability of underage.

However, without additional information on the costs associated with overage and underage, we cannot determine which cost is higher.

From the information given in the student question, it is clear that the probability of underage (PC) is less than 50%, as indicated by the shaded area under the graph.

To determine whether the cost of overage or the cost of underage is higher, follow these steps:
1. Identify the costs associated with overage and underage in the given context. Overage cost refers to the cost incurred when the inventory is higher than demand, while underage cost refers to the cost incurred when the inventory is lower than demand.
2. Analyze the graph or data provided to compare the costs of overage and underage. Since the student question does not provide any specific data or graph, we cannot accurately determine which cost is higher based on the given information.
3. Interpret the results. If the cost of overage is higher than the cost of underage, this means that having excess inventory is more expensive than having insufficient inventory.

Conversely, if the cost of underage is higher than the cost of overage, this means that not having enough inventory is more expensive than having excess inventory.

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

The standard deviation for this sample data set is 1.93.

What is deviation ?

Deviation refers to the difference between an individual value or observation and the average or mean value of a set of data. It can also refer to the extent to which a variable or set of data deviates from a standard or expected value.

To calculate the standard deviation for a sample data set, we first need to find the mean (average) of the data. In this case, the mean of the data set {5, 7, 6, 9, 6, 4, 4, 6, 5, 2, 5} is 5.45.

Once we have the mean, we can calculate the variance by taking the average of the squared differences between each data point and the mean. The variance is given by:

(1/n) * Σ(x_i - mean)^2

where n is the number of data points and x_i is the i-th data point.

The variance for this data set is 3.70.

Finally, we take the square root of the variance to get the standard deviation.

So, the standard deviation for this sample data set is 1.93.

There are a add up to of 8 cuts of pizza, and in the event that you haphazardly select a cut of cheese pizza to begin with, there are presently as it were 3 cuts of cheese pizza cleared out out of 7 add up to cuts cleared out. Since you need to discover the likelihood of selecting a cut of pepperoni pizza moment given that a cut of cheese pizza has as of now been chosen, you would like to calculate the likelihood of selecting a cut of pepperoni pizza from the remaining 4 cuts of pepperoni pizza and 3 cuts of cheese pizza.

The likelihood of selecting a slice of pepperoni pizza moment given that you simply have as of now chosen a cut of cheese pizza to begin with can be calculated utilizing the conditional likelihood equation:

P(Pepperoni moment | Cheese to begin with) = P(Pepperoni moment and Cheese to begin with) / P(Cheese to begin with)

The likelihood of selecting a cut of pepperoni pizza moment and a cut of cheese pizza to begin with is \(4/8 x 4/7 = 16/56\). The likelihood of selecting a cut of cheese pizza to begin with is 4/8, which disentangles to 1/2. Subsequently: P(Pepperoni moment | Cheese to begin with) = (16/56) / (1/2) = 4/7

places.)

To find the rate of change of P when t = 6, we need to take the derivative of P with respect to t and then evaluate it at t = 6.

P(t) = 19t/(t^2 + 90) + 0.14

Using the quotient rule, we can find the derivative of P:

P'(t) = [19(t^2 + 90) - 19t(2t)] / (t^2 + 90)^2

P'(6) = [19(6^2 + 90) - 19(6)(2(6))] / (6^2 + 90)^2

P'(6) = [19(216) - 456] / (216 + 90)^2

P'(6) = 342 / 9216 ≈ 0.037

Therefore, the rate of change of P when t = 6 is approximately 0.037.

We assume that G is a connected planar graph with no vertex of degree <= 5. We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices. Let d be the maximum degree of G.

Qa. Contrapositive of an implication is a new implication formed by negating both the hypothesis and the conclusion.

The contrapositive of the implication "If G is a connected planar graph, then G has at least one vertex of degree <= 5" is "If G has no vertex of degree <= 5, then G is not a connected planar graph."

Qb. Proof: We assume that G is a connected planar graph with no vertex of degree <= 5.

We will use e <= 3v - 6 to prove that G is not a planar graph. By handshaking lemma, we know that 2e = sum of degrees of all vertices.

Let d be the maximum degree of G. Since G has no vertex of degree <= 5, then d >= 6.

Thus, the sum of degrees of all vertices in G is greater than or equal to 6v/2, which is equal to 3v.

Hence, 2e >= 3v.

Substituting this inequality in e <= 3v - 6, we get 2e >= 3e - 6, which implies that e >= 6.

Since e >= 6, it follows that G is not planar.

Qc. Proof: We use proof by induction on the number of vertices of G. For a graph with one vertex, the statement is trivially true.

For a graph with n > 1 vertices, assume that every planar graph with at most n - 1 vertices can be colored with 6 (or less) colors.

Let G be a planar graph with n vertices.

By part (a), there exists a vertex v of G with degree <= 5.

We remove v and all its edges from G to get a new graph G' with n - 1 vertices.

By the induction hypothesis, we can color G' with 6 (or less) colors.

We add back v and its edges to G.

Since v has degree <= 5, at most 5 colors are used on its adjacent vertices.

We use a new color for v.

Thus, G can be colored with 6 (or less) colors.

Therefore, by induction, the statement is true for all planar graphs.

According to the given statement Betsy has traveled a total distance of 60 yards.

To find the total distance Betsy has traveled, we need to calculate the distance between each location and sum them up.

Given that one unit on the coordinate grid equals 10 yards, we can determine the distance between each location by finding the difference in their coordinates and multiplying it by 10.

The coordinates for Betsy's path are:
Location 1: (0, 0)
Location 2: (1, 0)
Location 3: (2, 0)
Location 4: (3, 0)

The distance between Location 1 and Location 2 is 1 unit, which is equal to 1 * 10 = 10 yards.

The distance between Location 2 and Location 3 is also 1 unit, which is equal to 1 * 10 = 10 yards.

The distance between Location 3 and Location 4 is 1 unit, which is equal to 1 * 10 = 10 yards.

To return back to Location 1, Betsy will need to travel from Location 4 to Location 1.

The distance between these two locations is 3 units, which is equal to 3 * 10 = 30 yards.

Area of sector: 48π in^2; Option D

Step-by-step explanation:

~ We can see that the bolded portion of the circle must be the the sector that we need to compute the area of... ~

Let us plan out this problem. If we were to find the area of the circle provided a radius of 12 inches, we could create a proportionality between the degree of the sector, and the degree of the circle ( 360 ) and the area of the sector and the area of the circle.

1. To calculate the area of this circle, let us apply the formula πr^2, such that r is 12 inches ( and let us keep π in terms of π ) ⇒ π * ( 12 )^2 ⇒ 144 * π ⇒ Area of Circle: 144π

2. Let us see this as a proportionality:

Degree of sector/ Degree of circle = Area of sector/ Area of circle

3. Now let us say x ⇒ Area of the sector. Substitute values into this formula, and solve for x through algebra:

120 / 360 = x / 144π,

120 * 144π = 360 * x,

17,280π = 360 * x,

x = 17,280π / 360,

Area of sector: 48π in^2
