Answer:

D.

Step-by-step explanation:

In direct variations, we would have:

q=kr

Where <em>k</em> is some constant.

Since this is indirect variation, instead of that, we would have:

q=\frac{k}{r}

To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>

<em />10=\frac{k}{2.5}\\k=2.5(10)=25<em />

Now plug this back into the variation:

q=\frac{25}{r}

The answer is D.

the monthly utility bills in a city are normally distributed, with a mean of $100 and a standard deviation of $12. Find the prob
vlada-n [284]

Answer:

0.7493 or 74.93%

Step-by-step explanation:

We are given;

Population mean; μ = 100

Population standard deviation; σ = 12

Sample mean 1; x1¯ = 90

Sample mean 2; x2¯ = 120

Z-score formula of the data given is;

z = (x¯ - μ)/σ

z1 = (90 - 100)/12

z1 = -0.83

z2 = (120 - 100)/12

z2 = 1.67

Since we wan to Find the probability that a randomly selected bill is between $90 to $120.

Thus;

P(90 < x¯ < 120) = P(−0.83 < Z < 1.67)

Probability will be gotten from online probability with 2 z-scores calculator to get;

P = 0.7493
