<span>The formula to find the z score in a normally distributed set of data is: z = (x - ÎĽ) / Ď With ÎĽ being the mean, Ď being the standard deviation, and x being the score. Substituting these values into the formula gives us z = (800 - 500) / 100 = 3 The z-score of the 800 point score is 3.</span>

The diameter of a spherical balloon that is being filled with air is increasing at the rate of 3 inches more than the time, t. W

Harrizon [31]

Answer:

$V=36 \pi$ cubic inches

Step-by-step explanation:

Diameter is increasing at 3 inches more than time, When t = 3

Diameter (d) = 3+3 = 6

d = 6

Radius is HALF of diameter, so

r = 6/2 = 3

Now, the volume of a sphere is given by the formula:

$V=\frac{4}{3}\pi r^3$

Putting r = 3, we get:

$V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}\pi (3)^3\\V=36 \pi$

The volume would be 36π
