Answer: 0.1587

Step-by-step explanation:

Given : Adult male heights have a normal probability distribution with a mean of 70 inches and a standard deviation of 4 inches.

i.e. \mu=70 ,\ \sigma=4

Let x be the random variable that represents the heights of adult males.

Also, z=\dfrac{x-\mu}{\sigma}

For x= 74 , we have

z=\dfrac{74-70}{4}=1

Then, the probability that a randomly selected male is more than 74 inches tall:-

P(x>74)=P(z>1)=1-P(z\leq1)\\\\=1- 0.8413447\\\\=0.1586553\\\\\approx0.1587 [using z-value table.]

Hence, the probability that a randomly selected male is more than 74 inches tall = 0.1587

A line passes through the points (7, 3) and (8, 3). What is its equation in slope-intercept form?
Sati [7]

Answer:

y=3

Step-by-step explanation:

The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3
