A function is a relation in which the members of the domain (x-values) do not repeat. So, for every x-value there is only one y-value that corresponds to it.

Charlie is late for the hot-air balloon rally. He stops his car 65 meters from a hot-air balloon already in flight. While Charli
aalyn [17]

Answer: 111.4m

Explanation:

1) Trigonometric ratios

You only need to use tangent ratio.

tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance

2) First, find the height of the ballon when he is watching at an angle of elevation of 28°

tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance

tan(28°) = balloon height/65m ⇒balloon height = tan(28°)×65m

balloon height = 34.56m

3) Second, find the height of the balloon,when he is watching at an angle of elevation of 66°

tan(66°) = height of the balloon / 65m ⇒ height of the balloon = tan(66°)×65m

height of the balloon = 145.99m

4) Vertical distance the balloon ascended while Charlie watched.

Subtract the final initial height from the final height:

145.99m - 34.56m = 111.43m

4) Round to the nearest tenth: 111.4 m

Assume standard deviation of all invoices is $200. Sample 100 invoices. What is the standard deviation of xbar
posledela

Answer:

<h3>20</h3>

Step-by-step explanation:

Standard deviation of the mean is expressed as:

SM = s/√n

s is the standard deviation of all invoices

n is the sample size of the invoiced

Given

s = $200

n = 100

Required

Standard deviation of the mean

Substitute the given parameters into the given equation

SM = 200/√100

SM = 200/10

SM = 20

Hence the standard deviation of xbar is 20
