For the new height requirements, this branch of the military requires women's heights to be at least 2.52 in and at most 6.96in.

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

(X is following normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex]  )

then it can be converted to standard normal distribution as

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

(Know the fact that in continuous distribution, probability of a single point is 0, so we can write

[tex]P(Z \leq z) = P(Z < z) )[/tex]

Also, know that if we look for Z = z in z tables, the p value we get is

[tex]P(Z \leq z) = \rm p \: value[/tex]

We are given that;

Mean= 63.8 in

Standard deviation= 2.3 in

Requirement of women height= 58in - 80in.

Now,

To find the minimum and maximum height requirements for this branch of the military, we need to use the standard normal distribution formula, which converts any normal distribution to a standard normal distribution with a mean of 0 and a standard deviation of 1.

We can find the z-scores for the minimum and maximum heights as follows:

For the minimum height requirement:

z = (58 - 63.8) / 2.3 = -2.52

For the maximum height requirement:

z = (80 - 63.8) / 2.3 = 6.96

Using a standard normal distribution table or calculator, we can find the corresponding probabilities for these z-scores:

For a z-score of -2.52, the probability is 0.0059 or 0.59%

For a z-score of 6.96, the probability is very close to 1, or 100%

Therefore, the new height requirements for this branch of the military are:

At least 58 inches, which corresponds to a z-score of -2.52

At most 80 inches, which corresponds to a z-score of 6.96

Based on the information provided, the statement "Ricardo is half as likely to spin a 2 or 4 than an odd number" is false.

To better understand if this is a valid statement, let's calculate the probability in each case.

Probability to get a 2 or 4:

1/ 8=  0.125 or 12.5% ( 0.125 x 100 = 12.5%)

Probability to get an odd number:

4/8 = 0.5 or 50% (0.5 x 100 = 50%)

This shows that the probability of getting a 2 or a 4 is 12.5%, while the probability of getting an odd number is 50%, which makes the statement false.

What is Triangle?

In geometry, a triangle is a two-dimensional closed shape with three straight sides and three angles. It is formed by connecting three non-collinear points with line segments. The three points of a triangle are called its vertices, and the line segments connecting them are called its sides.

If triangles ABC and DEF are congruent, then their corresponding sides are equal in length. Therefore, we have:

AB = DE = 41

BC = EF = 23

AC = DF = 36

We are given that BC = 4x - 7, so we can set up the following equation:

4x - 7 = BC = EF = 23

Solving for x, we get:

If two types of coffee. P and Q. are blended in the ratio 3: 13 by weight to form a standard blend X. The weight of type P coffee in 800g of X is 3x = 150g, and the weight of type Q coffee is 13x = 650g.

(a) Let the weight of P coffee in 3 parts of X be 3x, and the weight of Q coffee in 13 parts of X be 13x. Then, the total weight of X is 16x.

We know that the ratio of P to Q coffee in X is 3:13, so the total weight of P coffee in X is 3x, and the total weight of Q coffee in X is 13x. Therefore, the weight of each type of coffee in 800 g of X is:

P coffee = (3/16) * 800 g = 150 g

Q coffee = (13/16) * 800 g = 650 g

(b) Let the weight of P coffee in blend Y be x, the weight of Q coffee be 7x, and the weight of R coffee be 12x.

We know that the ratio of P to Q to R coffee in Y is 1:7:12, so the total weight of P coffee in Y is x, the total weight of Q coffee in Y is 7x, and the total weight of R coffee in Y is 12x. Therefore, the weights of type P coffee and type R coffee in 800 g of Y are:

P coffee = (1/20) * 800 g = 40 g

R coffee = (12/20) * 800 g = 480 g

(c) To form blend Z, we mix equal weights of X and Y. Therefore, the total weight of Z is 800 g + 800 g = 1600 g.

The weight of P coffee in Z is (150 g + 40 g)/2 = 95 g.

The weight of Q coffee in Z is (650 g + 7/20 * 800 g)/2 = 465 g.

The weight of R coffee in Z is (12/20 * 800 g + 480 g)/2 = 480 g.

Therefore, the ratio of P to Q to R coffee in blend Z is 95: 465: 480.

Answer:

Step-by-step explanation:

After one year, Devon's income will have grown by 2.9%. However, because inflation is 3.1%, the purchasing power of his income will decrease. This means that Devon will be able to buy less than he could today.

To calculate how much Devon can buy with his annual income after one year, we can use the following formula:

Purchasing power = Income / (1 + inflation rate)

Substituting the values given in the problem:

Purchasing power after one year = Income / (1 + 0.031)

Purchasing power after one year = Income / 1.031

Therefore, Devon will be able to buy approximately 0.97 times (or 97% of) what he could buy with his income today. In other words, his purchasing power will have decreased by approximately 3%.

Answer:

Devon's annual income increases at a rate of 2.9% per year, which means that after one year, his income will be 1.029 times his current income. However, due to inflation of 3.1% per year, the purchasing power of money decreases, which means that after one year, the amount of goods and services that can be purchased with the same amount of money will be 1/1.031 times what it is today.

Therefore, after one year, Devon can buy (1.029/1.031) times what he can buy today with his annual income. Simplifying this expression gives:

1.029/1.031 = 0.9971

So, Devon can buy about 99.71% of what he can buy today with his annual income after one year. In other words, he can buy slightly less than he can buy today, because inflation is greater than the rate at which his income is increasing.

The translation of the polygon is 6 units to the left

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

A translation in the coordinate plane moves every point on a figure a given distance in a given direction. The position of any point (x, y) on the figure changes to (x + a, y + b), where a and b are real numbers.

Given data ,

Let the polygon be represented as ABCD

Now , the coordinates of the polygon is given as

The coordinate of A = A ( 1 , 3 )

The coordinate of B = B ( 3 , -1 )

The coordinate of C = C ( 7 , -1 )

The coordinate of D = D ( 5 , 3 )

According to the provided dot plot, there appears to be a considerable variance in both medications' capacities to raise levels of human growth hormone. There is little crossover in the pieces of data for the two medicines, and the mean rise for Drug A is obviously greater than the average rise for Drug B.

We would need to do a formalized hypothesis test, which might involve a t-test, and generate a p-value to establish to see if this variance has statistical significance. We could conclude that the variation in averages is statistically significant if the p-value is less than a predetermined significance criterion (for example, 0.05).

Answer:

Step-by-step explanation:

To sketch the graph of the polynomial function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 without using technology, we can follow the following steps:

1. Determine the end behaviors of the graph: As x approaches negative infinity, the dominant term of the polynomial is x^4, which is positive. As x approaches positive infinity, the dominant term of the polynomial is also x^4, which is positive. Therefore, the end behaviors of the graph are both upward, which means that the graph rises to positive infinity on both ends.

2. Find the x-intercepts: To find the x-intercepts, we need to solve the equation P(x) = 0. One way to do this is to use synthetic division or long division to factor the polynomial. However, since the degree of the polynomial is 4, it may be difficult to find the roots algebraically. Alternatively, we can use technology or a graphing calculator to find the approximate values of the x-intercepts. Using a graphing calculator, we find that the x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.

3. Find the y-intercept: To find the y-intercept, we can set x = 0 in the equation P(x) = x^4 - x^3 - 11x^2 + 9x + 18, which gives P(0) = 18. Therefore, the y-intercept is (0, 18).

4. Determine the location of the minimum point: To find the location of the minimum point, we can use calculus and take the derivative of P(x) with respect to x. Setting the derivative equal to zero and solving for x, we find that x = -0.5 or x = 1. Therefore, the minimum point occurs at either (-0.5, P(-0.5)) or (1, P(1)). Using a graphing calculator, we find that the minimum value of P(x) is approximately -8.09, which occurs at x = -0.5.

Based on these steps, we can sketch the graph of P(x) as follows:

* The end behaviors of the graph are both upward.

* The x-intercepts are approximately -2.23, -0.43, 1.19, and 3.47.

* The y-intercept is (0, 18).

* The minimum point occurs at approximately (-0.5, -8.09).

* The graph is symmetric about the vertical line x = 0, since P(-x) = P(x) for all x.

5. To find where the company will break even, we need to find the values of x such that P(x) = 0. Using a graphing calculator or technology, we find that the company will break even at approximately x = -2.23, -0.43, 1.19, and 3.47. These correspond to the x-intercepts of the graph. Therefore, the company will break even at these values of x.

Answer:

140in^2

Step-by-step explanation:

Split the area into 3 different shapes, and solve for the area of each (see picture below)

For the first area, the left triangle, we have a length of 4 and a height of 7. So we're going to multiply these two numbers together, then divide by 2 since we're only solving for the area of a triangle and not a rectangle. This gives us 14in^2.

Next, we can simply multiply 15 by 7 to get an area of 105in^2, since this is a rectangle.

For the last area, we can do the same thing as the first. Multiply 6 by 7, then divide by 2, giving us 21in^2.

Finally, we can add up all of these areas to get the total area, and our final answer:

14+105+21=140in^2

Salma borrowed $15,300 and paid $295.24 per month for 5 years to pay off the loan.

What is loan?

In a loan, a certain quantity of money is given to another person in exchange for the value or main amount being repaid at a later date. In many circumstances, the lender increases the principal value by adding interest or finance charges, which the borrower must pay in addition to the principal sum.

To find out how much Salma borrowed, we can subtract her down payment from the cost of the motorcycle -

Loan amount = Cost of motorcycle - Down payment

Loan amount = 18,800 - 3,500

Loan amount = 15,300

Salma paid monthly payments for 5 years, which is equivalent to 60 months.

To calculate the monthly payments, we need to use the loan amount, the interest rate, and the loan term.

Let's assume the interest rate is 6%, which is a common rate for motorcycle loans.

We can use a loan calculator to find out the monthly payments -

Loan amount = 15,300

Interest rate = 6%

Loan term = 60 months

Using a loan calculator, we get a monthly payment of $295.24.

Therefore, Salma borrowed $15,300 and paid $295.24 per month.
