Billy is constructing a garden divided into 8 equal sections. The diameter of the garden is 12 feet. What is the area, in square

pishuonlain [190]

If the diameter of the garden is 12 ft, then the radius is 6 ft.

The area is then π(6 ft)^2, or 36 ft^2.

Then the area of one of the 8 equal sections of the garden is 36/8 ft^2, or 9/2 ft^2, or 4.5 ft^2.

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5

Doss [256]

Answer:

Using the Empirical Rule, we find that .997 (99.7%) of students have grade point averages that are between 1.23 and 3.81.

Step-by-step explanation:

Calculate the z-scores corresponding to a GPA of 1.23 and 3.81.

$\displaystyle z=\frac{1.23-2.52}{.43} = \frac{-1.29}{.43}= -3$
$\displaystyle z=\frac{3.81-2.52}{.43}= \frac{1.29}{.43} =3$

We want to find the area between the z-scores of -3 and 3.

The <u>Empirical Rule</u> tells us that 99.7% of the data lies <em>within three standard deviations</em> under the normal curve.

Therefore, the <u>area</u> between <em>-3 < z < 3</em> is about <u>.997</u>, or around <u>99.7%</u>.
