PLEASE HELP! Bob's Bricks has determined that a brick measuring 5 inches long has a z-score of +1 and a brick measuring 5.75 inches long has a z-score of +2.

What is the mean length of the bricks produced at Bob's Bricks?

A.4.00 inches
B. 4.25 inches
C. 4.75 inches
D. 5.25 inches

First, let's calculate the standard deviation of the bricks.

Standard deviation = 5.75 - 5 = 0.75

Now, we need to use the z-score formula to calculate the mean.

z-score = (observed value - mean) / standard deviation.

Let's plug our values into the formula above.

1 = (5 - mean) / 0.75

Multiply both sides by 0.75

0.75 = 5 - mean

Subtract 5 from both sides.

-4.25 = -mean

Divide both sides by -1

4.25 inches = mean

i hope this : )

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
