Answer:

30 degrees

Step-by-step explanation:

This is an isosceles triangle having 2 equal sides and 2 equal base angles.

since the measurement of all the internal angles of the triangle is 180 degrees and we know that each base angle is 75 degrees

solving for x:

75 + 75 + x = 180 degrees

150 + x = 180

x = 180 - 150

x = 30 degrees

The lifetimes of 10,000 watch batteries are normally distributed the mean lifetime is 500 days the standard deviation is 60 days

Lelu [443]

Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation

Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320

The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).
