In AMNO, the measure of Z0=90°, the measure of ZM=13°, and OM = 9.6 feet. Find
algol [13]

Answer:

Hypotenuse MN = 10.54 ft (Approx.)

Step-by-step explanation:

Given:

Base OM = 9.6 ft

Angle θ = 13'

Find:

Hypotenuse MN

Computation:

Using trigonometry function

Cos θ = Base / Hypotenuse

Cos 13 = 9.6 / Hypotenuse

0.97 = 9.6 / Hypotenuse

Hypotenuse MN = 10.54 ft (Approx.)

A lightbulb has a normally distributed light output with mean 5000 end foot-candles and standard deviation of 50 end foot-candle
Blizzard [7]
To find the specification limit such that only 0.5% of the bulbs will not exceed this limit we proceed as follows;
From the z-table, a z-score of -2.57 cuts off 0.005 in the left tail; given the formula for z-score
(x-μ)/σ
we shall have:
(x-5000)/50=-2.57
solving for x we get:
x-5000=-128.5
x=-128.5+5000
x=4871.50
