The heights of men in the US are normally distributed with a mean of 70 inches and a standard deviation of 3 inches. The heights of women in the US are
normally distributed with a mean of 65 inches and a standard deviation of 2.5
inches. If we select 1 man and 1 woman randomly from the population the
differences (M-W) should be normal as well. Assume the heights are independent of one another. Find the mean and standard deviation of the distribution of the differences in height. Then, use it to find the probability that the difference could be less than zero, which means that the woman selected is taller than the man selected.
A. P(X < 0) = 0.1003
B. P(X < 0) = 0.1814
C. P(X < 0) = 0.8186
D. P(X < 0) = 0.8997

i dont know i just need points

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
