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

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

<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>

Find the measure of each numbered angle.
Andrew [12]

Answer:

∠3 = 22°

∠4 = 22°

∠5 = 88°

86 + 72 = 158

180 - 158 = 22

∠3 ≅∠4 they're verticle angles

22+ 70 = 92

180 - 92 = 88
