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.

Answer:

$w = 28$

Step-by-step explanation:

$10(w-4) = 4(w+4)+4w$

1. distribute

$10w - 40 = 4w +16 +4w$

2. collect like terms

$10w -4w - 4w = 40 +16$

3. solve

A local television station for a city with a population of 500,000 recently conducted a poll where they invited viewers to call

Scilla [17]

Answer:

b. Invalid, because the sample may not be representative of the population.

Step-by-step explanation:

A sample of around 10% of the population is needed to be representative.

In this question:

We have a population of 500,000, and a sample of 10,000.

10,000/500,000 = 1/50 = 0.02 = 2% of the population, so not representative, and option b is correct.
