PLZ HELPPP MEEEE What is the difference between a rate and a unit rate

1 answer:

5 0

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

hope this helps!

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

$\bar x = \frac{\sum x}{n}$

Assume the data is:

$1287\ 1215\ 1221\ 1229$

This means that the number of schools is 4

So:

$\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}$

$\bar x = \frac{4952}{4}$

$\bar x = 1238$

The average of the assumed data is 1238
