All you have to do is multiply both sides by the same number to get an equivalent ratio.
Answer:
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour
Step-by-step explanation:
Ex: If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
120/3 = 40/1
The unit rate of 120 students for every 3 buses is 40 students per bus. You could also find the unit rate by dividing the first term of the ratio by the second term.
The rejection region is give by

where the test statistics is given by

i.e.

Thus,

Using the statistical table, the level of the test is 0.04.
Yes. It is simplified all of the way.
Answer:
The domain of a function is the set of its possible inputs, i.e., the set of input values where for which the function is defined. In other words, the domain of f is the set of real number R (and its set of possible outputs or codomain is also the set of real numbers R)
