Answer:

Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

The number of nuts in a can of mixed nuts is found to be normally distributed, with a mean of 500 nuts and a standard deviation
Elis [28]

Answer:

-2.25

Step-by-step explanation:

We have that the mean (m) is equal to 500, the standard deviation (sd) 20

They ask us for P (x <455)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / sd

We have all these values, replacing we have:

z = (455 - 500) / (20)

z = -2.25
