One important thing to note when dealing with probability problems is to look for the words 'or' or 'and'. If you encountered 'or', you'll have to add the probabilities. If you encounter 'and', you'll have to multiply them.

In this problem, you'll have to add the probability for the males and the probability for the smokers. Thus,

Probabilty = 22 + 57 = 79%

Mashutka [201]

Answer:

B. graph B

Step-by-step explanation:

The graphs of A,B,C and D are attached below.

Let x represent the credit amount  and y represent the minimum amount due.

For a bill of less than $100, the entire amount is due. That is for 0 ≤ x < $100, y = x

For a bill of at least $100 but less than $500, the minimum due is $100. That is for $100 ≤ x < $500, y = 100

For a bill of at least $500 but less than $1,000, the minimum due is $300. That is for $500 ≤ x < $1000, y = $300

For a bill of $1,000 or more, the minimum due is $500. But the credit limit is $2000. That is For $1000 ≤ x < $2000, y = $500

The graph that shows the minimum amount due for a credit amount of x  is graph B

Answer:

15 B

17 A

Step-by-step explanation:

A triangle is a figure with three sides.

Which can be re-written in the if-then form as If  the figure is a triangle then it has three sides.

The elevator has a MAX capacity of 8 people. This means that only 8 or less people can be on the elevator at a time. If c = # of people then c must be less than or equal to 8 as the elevator has a max capacity of 8 people. Hence the mathematical statement would be c ≤ 8

When the inequality sign is facing the "y" the solutions to the set can be found above the line. This could also be checked by graphing.
