Answer:

see attached

Step-by-step explanation:

We cannot really do the construction for you, but we can tell you how it needs to go. The three sides of the triangle will have a length in cm that is equal to the given length in km divided by 20.

AB = 6 cm

BC = 8 cm

AC = 9 cm

The area each station can be heard will be a circle of radius (100 km)/(20 km) cm = 5 cm. The overlap of those circles is the area you are to shade.

The attached diagram should give you the general idea. (Scale units are cm.)

_____

Additional comment

It works well to find B as the intersection of arcs of radius 6 cm and 8 cm, drawn from centers A and C, respectively.

A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean l

Answer:

The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors

P(X⁻ ≥ 96.3) = 0.0087

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 95

Given that the standard deviation of the Population = 5

Let 'X' be the random variable in a normal distribution

Let X⁻ = 96.3

Given that the size 'n' = 84 monitors

Step(ii):-

The Empirical rule

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{96.3 - 95}{\frac{5}{\sqrt{84} } }$

Z = 2.383

The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors

P(X⁻ ≥ 96.3) = P(Z≥2.383)

= 1- P( Z<2.383)

= 1-( 0.5 -+A(2.38))

= 0.5 - A(2.38)

= 0.5 -0.4913

= 0.0087

Final answer:-

The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors

P(X⁻ ≥ 96.3) = 0.0087

The weight of water is 62 and one half lb per cubic foot. How many cubic feet would be occupied by 180 lb of water?

inessss [21]

Answer:

$2\frac{22}{25}$ cubic feet

Step-by-step explanation:

We are given that the weight of water is 62 and one half lb per cubic foot and we are to find the number of cubic feet that would be occupied by 180 lb of water.

For that, we will divide total amount of water by per unit weight of water:

Cubic feet occupied by 180 lb of water = $\frac{180}{62.5} =$ = 2.88 cubic feet or $2\frac{22}{25}$ cubic feet
