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
<u>The result would be normCdf(0.48,9999,0,1) ≈ </u><u>0.315614</u>

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
- Lower bound = -9999
- Upper bound = 0.79
- Mean = 0
- Standard deviation = 1
<u>The result would be normCdf(-9999,0.79,0,1) ≈</u><u> 0.785236</u>
<span>3x + (x-8) = 23
Combine like terms first. You can combine 3x and x because they have the same variable.
4x - 8 = 23
Now add 8 to both sides.
4x = 31
Last step is to divide both sides by 4 to isolate the x.
4/4x = 31/4
x = 7.75 is the answer.</span>
