Let X represent the number of homes a real estate agent sells during a given month. Based on previous sales​ records, she estimates that Upper P left parenthesis 0 right parenthesis equals 0.63​, Upper P left parenthesis 1 right parenthesis equals 0.21​, Upper P left parenthesis 2 right parenthesis equals 0.12​, Upper P left parenthesis 3 right parenthesis equals 0.03​, Upper P left parenthesis 4 right parenthesis equals 0.01​, with negligible probability for higher values of x. a. Explain why it does not make sense to compute the mean of this probability distribution as left parenthesis 0 plus 1 plus 2 plus 3 plus 4 right parenthesis divided by 5 equals 2.0. b. Find the correct mean and interpret.

try soting them out first

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
