A coat that originally sold for $369.00 is on sale at a 40% discount? How much will you pay for the coat?
Triss [41]
The coat will cost $221.40. If you move a decimal two spaces to the left from 40% (.40) and multiply it by $369.00, you'll get $147.60. You then subtract $147.60 from $369.00 and get $221.40, the final price of the coat.

Ilia_Sergeevich [38]

Using sampling concepts, it is found that the correct option is given by:

B. The Golf Federation's conclusion was not valid because the sample was biased since the male customers all lived in California.

<h3>What is sampling?</h3>

It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.

In this problem, the objective is to make an estimate about the most popular brand of golf ball from men all over the United States, however, only customers from California were chosen, hence the sample is not representative and option B is correct.

Hoochie [10]

20 people

Step-by-step explanation:

those 3 dollars times the number of people must give 60 dollars

3x=60\\\\\frac{1}{3} *3x=\frac{1}{3} *60\\\\x=20

so 20 people must go, to pay only $10
