Ms. murphy has to create a relay team in 3024 ways.

What is combination?

A combination is a collection of components produced under a certain set of constraints and conditions.

Selections are another name for combinations. The choice of items from a predetermined group of items corresponds to combinations. We don't want to organize anything here. We are going to choose them. We use the symbols n C r to represent the number of distinct r-selections or combinations among a set of n items.

As given, Ms murphy has to select 4 swimmers out of 9  swimmers to create a relay team.

By using the combination formula we can find the number of ways to create a relay team.

\(C^{n}_r = \frac{n!}{(n-r)!}\)

Where,

n is the number of all objects and r is a number of selected objects.

Here, n = 9 and r = 4.

So,

\(C^{9}_4 = \frac{9!}{(9-4)!} = \frac{9!}{5!} = \frac{x}{y} = 3024\)

Therefore, she create a relay team in 3024 ways.

84 x 5 = 420 (the sum of the five numbers)

71 + 81 + 94 + 77 = 323

420 - 323 = 97

You can double check your work by finding the average of the 5 numbers: (71+81+94+77+97) / 5 = 84

So, 97 is the missing test grade.

Answer: 96

Step-by-step explanation:

A palindrome is a number that is the same when reading in both ways (right to left, and left to right), for example, 121

Then, we have 9 digits, and all the digits need to be even.

the options are: 0, 2, 4, 6, 8.

Now, we can think of a 9-digit number as 9 empty slots, and in each slot, we can put a number.

But because this is a palindrome, the first digit must be equal to the ninth, and the second digit must be equal to the eight, and so on.

So, we can think it as actually only 5 slots, where in each slot, we can put an even number, now let's count the options that we have in each selection.

For the first digit we have 4 options: 2, 4, 6 and 8 (0 is not counted here because if the first digit was a 0, then this would not be a 9-digit number).

for the second digit, we have also 4 options (because we already toked one, but now the 0 can be chosen)

for the third digit, we have 3 options

for the fourth digit, we have 2 options

for the fifth digit, we have only one option.

The total number of combinations is equal to the product of the number of options for each selection:

C = 4*4*3*2*1 = 96

The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x. The cab charges $0.88 for a ride of 2 miles. And the cab charges $1.72 for a trip of 8 miles.

a. The equation for traveling x miles in the cab can be written as:

Cost = $0.60 + $0.14 * x

b. To find the number of miles for a cab ride that costs $0.88, we can set up the equation:

$0.88 = $0.60 + $0.14 * x

Subtracting $0.60 from both sides, we get:

$0.88 - $0.60 = $0.14 * x

$0.28 = $0.14 * x

Dividing both sides by $0.14, we find:

x = $0.28 / $0.14

x = 2 miles

Therefore, the cab charges $0.88 for a ride of 2 miles.

c. To calculate the cost of a trip of 8 miles, we can substitute x = 8 into the equation:

Cost = $0.60 + $0.14 * 8

Cost = $0.60 + $1.12

Cost = $1.72

Therefore, the cab charges $1.72 for a trip of 8 miles.

The probability that their first child will be a phenotypically normal girl is 3/8 or 37.5%.

Lou Gehrig's disease, also known as amyotrophic lateral sclerosis (ALS), is typically considered as an autosomal recessive disease. This means that both copies of the gene responsible for the disease need to be inherited, one from each parent, in order for an individual to be affected by the disease.

Given that the woman and her husband are both carriers of the disease, they each have one copy of the mutated gene and one normal gene. The probability of passing on the mutated gene to their child is 1/2 for each parent since they are carriers.

To determine the probability of their first child being a phenotypically normal girl, we need to consider the inheritance pattern. Let's break it down:

Gender: The probability of having a girl is 1/2, as gender is determined by the combination of the father's sperm (containing either an X or a Y chromosome) and the mother's egg (containing an X chromosome).

Phenotypically normal: For the child to be phenotypically normal, they should inherit at least one normal gene from either parent. The probability of inheriting a normal gene from the mother is 1/2, and the same probability applies for inheriting a normal gene from the father.

Independence: The probability of having a girl and inheriting a normal gene are independent events, so we can multiply their individual probabilities to calculate the combined probability.

Therefore, the probability of having a phenotypically normal girl is:

Probability of being a girl × Probability of inheriting a normal gene

= (1/2) × (1/2)

= 1/4

However, we also need to consider the possibility of having a boy. The probability of having a phenotypically normal boy is also 1/4.

Adding the probabilities of having a phenotypically normal girl and a phenotypically normal boy, we get:

1/4 + 1/4 = 2/4 = 1/2        

Since the question specifically asks for the probability of having a phenotypically normal girl, we divide the probability of a phenotypically normal girl by the total probability of having a child:

(1/4) / (1/2) = 1/4 * 2/1 = 1/2 = 2/4 = 1/2

Therefore, the probability that their first child will be a phenotypically normal girl is 1/2 or 50%.

To solve this problem, we can use trigonometry. The tangent of the angle of elevation is equal to the opposite side (height of porch) divided by the adjacent side (length of ramp). So.

tan(24°) = 30/x

where x is the length of the ramp.

To solve for x, we can cross-multiply:

x * tan(24°) = 30

x = 30 / tan(24°)

Using a calculator, we get the following:

x = 73.76 inches

Therefore, the length of the ramp is 73.76 inches.
To find the size of the wheelchair ramp, we can use the angle of elevation and trigonometry concept. We know that the angle of elevation is 24°, and the height of the porch is 30 inches.

We can use the sine function to relate the angle, height, and length of the ramp:

sin(angle) = opposite side / hypotenuse

In this case, the opposite side is the height of the porch (30 inches), and the hypotenuse is the length of the ramp (which we want to find).

sin(24°) = 30 inches/length of the ramp

Now, we need to solve for the length of the ramp:

length of ramp = 30 inches / sin(24°)

Using a calculator to find the sine value and divide:

length of ramp ≈ 30 inches / 0.40775 ≈ 73.60 inches

The closest answer from the provided options is 73.76 inches. So, the length of the ramp is approximately 73.76 inches.

The future value of the deposits at the end of 5 years is approximately $6,138.74.

To calculate the future value of the deposits, we can use the formula for compound interest:

FV = P(1 + r/n)^(nt)

Where: FV is the future value

P is the principal amount (initial deposit)

r is the annual interest rate (3% in this case)

n is the number of times interest is compounded per year (quarterly in this case)

t is the number of years

In this case, the principal amount is $1,000, the annual interest rate is 3% (or 0.03), the number of times interest is compounded per year is 4 (quarterly), and the number of years is 5.

Plugging in these values into the formula, we get: FV = $1,000(1 + 0.03/4)^(4*5)

Calculating this, the future value of the deposits at the end of 5 years is approximately $6,138.74.

The reorder point for the product is 36 units.

To determine the reorder point, we need to consider the average daily sales and the average lead time.

Average daily sales: The average daily sales of the product are given as 8 units.

Average lead time: The average lead time for delivery is 4 days, with probabilities of 0.2, 0.6, and 0.2 for 3, 4, and 5 days, respectively. We can calculate the expected lead time as follows:

Expected lead time = (Probability of 3 days * 3) + (Probability of 4 days * 4) + (Probability of 5 days * 5)

Expected lead time = (0.2 * 3) + (0.6 * 4) + (0.2 * 5)

Expected lead time = 0.6 + 2.4 + 1

Expected lead time = 4 days

Reorder point calculation: The reorder point is the inventory level at which an order needs to be placed to avoid stockouts. It is determined by multiplying the average daily sales by the average lead time. In this case:

Reorder point = Average daily sales * Average lead time

Reorder point = 8 units * 4 days

Reorder point = 32 units

Therefore, the reorder point for the product is 32 units.

The provided random numbers (sets 1 and 2) are not used in the calculation of the reorder point. They might be relevant for other parts of the problem or for future analysis, but they are not necessary for determining the reorder point in this case.
