Can someone help I’m not good with word problems

pickupchik [31]

Answer:

I agree that this question can be confusing:

Apparently point A and point B must be on the same straight line (measured from the light house or the question would be nonsensical)

tan 13 = H / DA where H is height of lighthouse

tan 8 = H / DB tangent measured from point B

tan 13 / tan 8 = DB / DA

DB = .2309 / .1405 * 1279 = 2101 ft

DB - DA = 2101 - 1279 = 822.0 ft

An air conditioning system can circulate 320 cubic feet of air per minute. How many cubic yards of air can it circulate per minu

Agata [3.3K]

Step-by-step explanation:

It is given that, an air conditioning system can circulate 320 cubic feet of air per minute. We need to find how many cubic yards of air can it circulate per minute?

1 yard = 3 foot

1 feet = (1/3) yard

320 feet = 106.66 yard

$320\ \text{feet}^3=320\times( \dfrac{1}{3})^3\ \text{yard}^3\\\\=11.85\ \text{yard}^3$

So, it will circulate 11.85 cubic yard of air per minute.

If a set of sample measurements has a mean of 100, a normal distribution, a standard deviation of 2, and control limits of 94 an

weeeeeb [17]

Answer: 99.73%

Step-by-step explanation:

Given : Mean : $\mu=100$

Standard deviation : $\sigma=2$

Let X be the random variable that represents the data values.

Formula for Z-score : $z=\dfrac{X-\mu}{\sigma}$

For x=94, we have

$z=\dfrac{94-100}{2}=-3$

For x=106, we have

$z=\dfrac{106-100}{2}=3$

The probability that the samples are between 94 and 106:-

$P(-3$

Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
