Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches.
nexus9112 [7]

Answer: 0.84134

Step-by-step explanation:

We need to find the z-score for the given information first since this will help us find the probability. The formula for this is

Z score = \frac{x - \mu}{\sigma}

We have

x = 66 inches (the raw score)

\mu = 70 inches (the population mean)

\sigma = 4 inches (the standard deviation)

This gives

Z score = \frac{x - \mu}{\sigma} = \frac{66-70}{4} = -1

If you use a calculator, or a Z-score table then P(x > Z) is just P(Z > -1) which gives a probability of 0.84134.

jeds market has a total of 26 employees. Each full time employee makes $275/ week, and each part-time employee makes $140/ week.
I am Lyosha [343]

Answer:

f=17\\p=9\\

Step-by-step explanation:

Let

f= Full-time\\p=Part-time

Full time rates-$275, Part-time rates-$140

The problem can be expressed as:

f+p=26...eqtn1\\275f+140p=5935....eqtn2\\

Express eqtn1 in terms of f,f=26-p

Substitute f value in eqtn 2.

=>275(26-p)+140p=5935\\7150-275p+140p=5935\\1215=135p\\p=9\\f=26-9=17\\

Therefore,  jeds has 17 fulltime and 9 parttime employees.

The lines intersect at point C. What is the value of x?
Agata [3.3K]

<u>Answer:</u>

The correct answer option is 21.

<u>Step-by-step explanation:</u>

We know that the given lines PW and AD intersect at the point C.

Therefore, the two given angles are equal to each other and we can write them in the form of an equation as:

(4x - 4)° = (3x + 17)°

Solving for x to get:

4x - 4 = 3x + 17

4x - 3x = 4 + 17

x = 21

Therefore, the value of x is equal to 21.
