Answer:

The internship pays $7.5 an hour.

Step-by-step explanation:

From the information given, the equation would indicate that the amount the student earns per hour at the intership for two plus seven would be equal to 22:

2x+7=22

Now, you can solve for x:

2x=22-7

2x=15

x=15/2

x=7.5

According to this, the answer is that the internship pays $7.5 an hour.

Stella’s farm consists of 240 acres upon which she wishes to plant pumpkins and squash.
Nutka1998 [239]

The profit is maximized whenn 80 acres of pumpkin and 160 acres of squash is cultivated to make $80000.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of pumpkin acre and y represent the number of squash acre, hence:

x + y ≤ 240  (1)

Also:

20x + 10y ≤ 3200 (2)

The solution is at x = 80, y = 160

Maximum profit = 400x + 300y = 400(80) + 300(160) = $80000

The profit is maximized whenn 80 acres of pumpkin and 160 acres of squash is cultivated to make $80000.

The ages of a group of 135 randomly selected adult females have a standard deviation of 18.3 years. Assume that the ages of fema
NeTakaya

Answer:

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student is 3625 female statistics student

Step-by-step explanation:

Here, we have

n = \left (\frac{(z_{\alpha/2}) (\sigma) }{E}   \right )^{2}

Where:

n = Required sample size

σ = Standard deviation = 18.3

E = Margin of error = 1/2 year

z_{\alpha /2} = Critical score from the confidence level = 1.645

Therefore,

n = \left (\frac{(1.645) (18.3) }{\frac{1}{2} }   \right )^{2} = 3624.88

Therefore, the number of female statistics student ages that must be obtained in order to estimate the mean age of all female statistics student = 3625 female statistics student.
