Aisha owns an apparel store. She bought some shirts and jeans from a wholesaler for $3,900. Each shirt cost $12 and each pair of jeans cost $28. If she sold the shirts at 70% profit and jeans at 125% profit, her total profit was $3,885. How many shirts and jeans did she buy from the wholesalers?

Answers

Let

x-------> the number of shirts

y------> the number of jeans

we know that

$12x+28y=3,900$ -------> equation $1$

If she sold the shirts at $70\%$ profit and jeans at $125\%$ profit, her total profit was $\$3,885$

$1.7*(12x)+2.25*(28y)=3,900+3,885$

$20.4x+63y=7,785$ -------> equation $2$

we have the following system of equations

$12x+28y=3,900$ -------> equation $1$

$20.4x+63y=7,785$ -------> equation $2$

using a graph tool

see the attached figure

The solution of the system is the intersection both graphs

the solution is the point $(150,75)$

that means

$x=150\ shirts\ny=75\ jeans$

therefore

the answer is

the number of shirts is $150$

the number of jeans is $75$

Let the number of shirts be x, and the jeans be y.

Total cost of shirts = 12x
Total cost of Jeans = 28y

This means that: 12x + 28y = 3900..........(a)

Selling price for Shirts 70% profit, means = 100% + 70% = 170% of the cost price

170/100 * 12x = 1.7*12x = 20.4x

Selling price for Jeans 125% profit, means = 100% + 125% = 225% of the cost price

225/100 * 28y = 2.25*28y = 63y

Total profit = 3885, remember total cost = 3900

Total selling price = 3885 + 3900 = 7785

20.4x + 63y = 7785..........(b)

12x + 28y = 3900.............(a)

20.4x + 63y = 7785...........(b)

Solving the simultaneous equation with a programmable calculator:

x = 150, y = 75

150 shirts and 75 jeans.

An airliner carries 200 200 passengers and has doors with a height of 70 70 in. Heights of men are normally distributed with a mean of 69.0 69.0 in and a standard deviation of 2.8 2.8 in. Complete parts (a) through (d). a. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending. The probability is . 6395 . (Round to four decimal places as needed.)b. If half of the 200 200 passengers are men, find the probability that the mean height of the 100 100 men is less than 70 70 in. The probability is nothing . (Round to four decimal places as needed.) c. When considering the comfort and safety of passengers, which result is more relevant: the probability from part (a) or the probability from part (b)? Why? A. The probability from part (a) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height. B. The probability from part (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height. C. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend. D. The probability from part (b) is more relevant because it shows the proportion of male passengers that will not need to bend. d. When considering the comfort and safety of passengers, why are women ignored in this case? A. There is no adequate reason to ignore women. A separate statistical analysis should be carried out for the case of women. B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women. C. Since men are generally taller than women, it is more difficult for them to bend when entering the aircraft. Therefore, it is more important that men not have to bend than it is important that women not have to bend.

Answers

Using the normal distribution and the central limit theorem, it is found that:

a) The probability is 0.6395.

b) The probability is 1.

The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend.

B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = (X - \mu)/(\sigma)$

It measures how many standard deviations the measure is from the mean.
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
By the Central Limit Theorem, for the sampling distribution of samples of size n, the standard deviation is $s = (\sigma)/(√(n))$

In this problem:

Mean of 69 in, thus $\mu = 69$ .
Standard deviation of 2.8 in, thus $\sigma = 2.8$ .

Item a:

This probability is the p-value of Z when X = 70, thus:

$Z = (X - \mu)/(\sigma)$

$Z = (70 - 69)/(2.8)$

$Z = 0.357$

$Z = 0.357$ has a p-value of 0.6395.

Thus, the probability is 0.6395.

Item b:

Samples of size 100, thus $n = 100, s = (2.8)/(√(100)) = 0.28$ .

This probability is the p-value of Z when X = 70, thus:

$Z = (X - \mu)/(\sigma)$

By the Central Limit Theorem:

$Z = (X - \mu)/(s)$

$Z = (70 - 69)/(0.28)$

$Z = 3.57$

$Z = 3.57$ has a p-value of 1.

The probability is 1.

Item c:

We want don't want many people to have to bend, thus, part a has to be considered.

Item d:

Generally, men are taller, so if the design accommodates the men, it will accommodate the women, and the correct option is:

B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.

A similar problem is given at brainly.com/question/24663213

Answer:

a) 0.6406; b) 1.000; c) C. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend; d) B. Since men are generally taller than women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.

Step-by-step explanation:

For part a,

We use the formula for the z score of an individual,

$z=(X-\mu)/(\sigma)$

Our mean, μ, is 69 and our standard deviation, σ, is 2.8. To find P(X < 70),

z = (70-69)/2.8 = 1/2.8 = 0.36

Using a z table, we see that the area under the curve to the left of this value is 0.6406. This is our probability.

For part b,

We use the formula for the z score of a sample,

$z=\frac{\bar{X}-\mu}{\sigma / √(n)}$

Our mean is still 69 and our standard deviation is still 2.8. Our sample size, n, is 100. To find P(X < 70),

z = (70-69)/(2.8÷√100) = 1/(2.8÷10) = 1/0.28 = 3.57

Using a z table, we see the area under the curve to the left of this is greater than 0.9999. This means that the probability is 1.000.

For part c,

We want to know the proportion of male passengers that will not need to bend. This is why the value from part a is more important.

For part d,

Men taller on average than women. This means if we accommodate for the mean, it follows that the women will fit as well.

Answers

In the question "Harriet earns the same amount of money each day. Her gross pay at the end of 7 work days is 35h + 56 dollars. Which expression represents her gross pay each day" To obtain the expression that represents her gross pay each day, we divide the given expression by 7 to get (35h + 56) / 7 = 35h / 7 + 56 / 7 = 5h + 8 Therefore, the expression that represents her gross pay each day is 5h + 8.
