If one of the 255 subjects is randomly selected, find the probability that the person is over 40 and prefers cola.

Under the "cola" heading, to the right of "under 40 years of age," we find the count 20. This is the number of subjects who 1) prefer cola AND 2) are over 40. The probability that one of these 20 subjects will be chosen is 20/255, or .078.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
