A baker puts 5 cups of fruit into each pie he bakes. he pays $0.75 for 1 cup of fruit and $2.50 for the pie crust. He sells each

kirill [66]

Answer:

He earn $40

Step-by-step explanation:

To solve this problem, we first have to calculate how much it spends to make each pie

cups of fruit = 5

5 * $0.75 = $3.75

This means that per pie he spends $ 3.75 on cups of fruit and $ 2.50 on pie crust

If we add them together we will get how much he spends for each pie

$3.75 + $2.50 = $6.25

Now to the price that the pie sells we subtract this value to know how much you earn for each pie

$10.25 - $6.25 = $4

if he sold 10 pies we multiply this number by 10 and we will get his total profit

$4 * 10 = $40

He earn $40

The heights of 18-year-old men are approximately normally distributed with mean 68 inches and standard deviation 3 inches. What

Nutka1998 [239]

Answer:

The probability that an 18-year-old man selected at random is greater than 65 inches tall is 0.8413.

Step-by-step explanation:

We are given that the heights of 18-year-old men are approximately normally distributed with mean 68 inches and a standard deviation of 3 inches.

Let X = heights of 18-year-old men.

So, X ~ Normal( $\mu=68,\sigma^{2} =3^{2}$ )

The z-score probability distribution for the normal distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean height = 68 inches

$\sigma$ = standard deviation = 3 inches

Now, the probability that an 18-year-old man selected at random is greater than 65 inches tall is given by = P(X > 65 inches)

P(X > 65 inches) = P( $\frac{X-\mu}{\sigma}$ > $\frac{65-68}{3}$ ) = P(Z > -1) = P(Z < 1)

= 0.8413

The above probability is calculated by looking at the value of x = 1 in the z table which has an area of 0.8413.
