In a certain ASU classroom, the weight of men is an average of 175 pounds, with a standard deviation of 20 pounds. Assuming a no

Alenkinab [10]

Answer:

99.8%

Step-by-step explanation:

Normal Distribution

Standard deviation σ

mean equal to 175 pounds

We should remember approximately values for intervals:

[μ - σ/2 : μ + σ/2] values spread 1σ up and down mean equal to 68.3 %

[μ - σ : μ + σ ] values spread 2σ up and down mean equal to 95.7 %

and finally

[μ - 1.5 σ : μ + 1.5 σ ] values spread 3σ up and down mean equal to 99.7

In our case we were asked porcentage between 4σ (40 kg) spread about mean

175 + 40 = 215

175 - 40 = 135

For that interval we should get 99.8% of values

In triangle ABC,D is a point on side AC such that BD=DC and angle BCD measures 70 degrees. What is the measure if of angle ADB?

mars1129 [50]

If BD=DC that means triangle CDB is isosceles triangle and the measure of angles ∡CDB and ∡BCD is the same
   ∡CDB=∡BCD=70°

The angles ∡ADB and ∡CDB are adjacent and suplementary angles

It means ∡ADB + ∡CDB = 180°
      ∡ADB = 180° - ∡CDB
      ∡ADB = 180° - 70°
      <u>∡ADB = 110°</u>
