Plot two points that are 777 units from Point \blueD{D}Dstart color #11accd, D, end color #11accd and also share the same xxx-co
Karolina [17]

Right format of question:

Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.

Answer:

D' = (-4,-6) and D' = (-4,8)

Step-by-step explanation:

Given

D(x,y) = (-4,1)

Required

Determine a point 7 points from D and in the same x coordinate

Represent this point with D'.

From the requirement of the question, D' has two possible values and these values are:

D' = D(x,y-7) ----> 7 units down and

D' = D(x,y+7) ----> 7 units up

Substitute values for x and y in D' = D(x,y-7) and D' = D(x,y+7)

So, we have:

D' = D(x,y-7)

D' = (-4,1 - 7)

D' = (-4,-6)

D' = D(x,y+7)

D' = (-4,1+7)

D' = (-4,8)

According to the empirical rule, 68% of 7-year-old children are between ___ inches and ___ inches tall.
AveGali [126]

Using the empirical rule 68% would fall within one standard deviation of the mean.

The standard deviation is given as 2 inches and the mean is 49 inches.

Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.

49 - 2 = 47

49 + 2 = 51


68% would be between 47 inches and 51 inches tall.
