Answer:

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

Cloud [144]

Answer:

The mistake in Kevin's calculation is when calculating P(Red or Green).

Step-by-step explanation:

Given

$Sections = 10$

$Spins = 180$

$Red, Blue, Green, Yellow, Purple = 2\ each$

Required

Spot the mistake in Kevin's calculation

From the question, we have that:

Kevin's calculation

$P(Red\ or\ Green) = \frac{2}{10}$

Number of times;

$Times = \frac{2}{10} *180 = 36$

The mistake in Kevin's calculation is when calculating P(Red or Green).

$P(Red\ or\ Green) = \frac{Number\ of\ red\ or\ green}{Total}$

He considered only one section instead of both sections

The correction is:

Since, there are 2 green sections and 2 red sections.

The equation becomes

$P(Red\ or\ Green) = \frac{2 + 2}{10}$

$P(Red\ or\ Green) = \frac{4}{10}$

And the number of times is:

$Times = \frac{4}{10} * 180$

$Times = \frac{720}{10}$

$Times = 72$

Margarita [4]

88 inches is the answer
the area of the circular base is 25pi, since diameter is 10 that means radius is 5, raise it to second power and multily pi.
divide 2200pi by 25pi
therefore its height is 88 inches
