If you would fill in the blanks, that would really be appreciated!

Triss [41]

Answer:

By applying the slope formula , I find that the slope of segment DE is zero since the difference between the y coordinates of points D and E is zero and any number divided into zero is zero. The slope of segment AB is also zero because (0-0) /(x2-0) =0 Because the two segments have the same slope they must be parallel according to the definition of parallel lines.

Step-by-step explanation:

slope formula = (y2-y1)/(x2-x1)

slope for DE = (y1/2-y1/2)/((x1+x2/2 - x1/2)

= 0 /(x2/2)

= 0

slope for AB = (0-0)/((x1+x2/2 - x1/2)

= 0 /(x2-0)

= 0/x2

Parallel lines have the same slope

The heights of American men have an approximately bell-shaped distribution with a mean of 70 inches (5' 10") and standard deviat

Katyanochek1 [597]

Answer:

0.9973 is the percentage of American men whose height is between 61 and 79 inches.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 70 inches

Standard Deviation, σ = 3 inches

We are given that the distribution of heights of American men is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(height is between 61 and 79 inches)

$P(61 \leq x \leq 79) = P(\displaystyle\frac{61 - 70}{3} \leq z \leq \displaystyle\frac{79-70}{3}) = P(-3 \leq z \leq 3)\\\\= P(z \leq 3) - P(z < -3)\\= 0.9987 - 0.0014 = 0.9973= 99.73\%$
