Answer:
a. 19.68 miles per gallon.
b. 26.32 miles per gallon.
Step-by-step explanation:
Mean gas mileage (μ) = 23.0 mpg
Standard deviation (σ) = 4.9 mpg
In a normal distribution, for any length X, the z-score is determined by the following expression:

In a normal distribution, the 25th percentile (first quartile) of a normal distribution has a corresponding z-score of z = -0.677 and the 75th percentile has a corresponding z-score of z = 0.677
a. The first quartile of the distribution of gas mileage is

19.68 miles per gallon.
b. The third quartile of the distribution of gas mileage is

26.32 miles per gallon.
1. Pint
2. Gallon
Hope this helps.
The answer is A.
Divide 300 by the number of faces of a cube.
Since there are 6 faces on a cube then we divide it.
300 ÷ 6 = 50.
So exactly 50 times.

Answer:
<em>The height of the cylinder 'h' = 4 inches</em>
Step-by-step explanation:
<u><em>Explanation</em></u> :-
<em>Given diameter of the cylinder ' d' = 10 inches</em>
Diameter of the cylinder <em>d = 2 r </em>
<em>Radius of the cylinder </em>
<em> </em>
Given Volume of the cylinder 'V' = 314 cubic inches
<em>Volume of the cylinder Formula</em>
<em> V = π r² h</em>
3 14 = 3.14 (5)² h

<em> h = 4</em>
<em>The height of the cylinder 'h' = 4 inches</em>
