Answer:

A coordinate grid is shown from negative 10 to positive 10 on the x axis and also on the y axis. Two lines are shown intersecting on the ordered pair 3, 8.

Step-by-step explanation:

Finding the solution of these 2 equations

y = -2x + 14
y = 2x + 2

Equating them :

-2x + 14 = 2x + 2
2x + 2x = 14 - 2
4x = 12
x = 3

Substitute in a equation to find y :

y = 2(3) + 2
y = 6 + 2
y = 8

The solution is (3, 8).

The 1st explanation is the correct one.

Determine the area under the standard normal curve that lies to the right of the z-score 0.48 and to the left of the z-score 0.7

pychu [463]

Answer:

The area lies to the right of the z-score 0.48 means all the values greater than it. This can be calculated on a graphing calculator using the function normCdf, where

Lower bound = 0.48
Upper bound = 9999
Mean = 0
Standard deviation = 1

The result would be normCdf(0.48,9999,0,1) ≈ 0.315614

The area lies to the left of the z-score 0.79 means all the values less than it. This can be calculated on a graphing calculator using the function normCdf, where
