Answer:
35% chose baseball or soccer
Step-by-step explanation:
baseball or soccer = 20% + 15% = 35%
_____
The categories add to 100%, so are mutually exclusive, as you expect when they are "favorite sport" categories. Hence the union of two of them will be their sum. (Otherwise, you'd have to subtract the amount by which the categories overlap.)
The correct answer is D. NURSING AIDES HAD FEWER PEOPLE IN 2002.
<span>Employment Projections
Job Number of People (2002) Projection (2012) Percent Change
Nursing Aides 1,375,000 1,718,000 25
Customer Service 1,894,000 2,354,000 24
(1,718,000 - 1,375,000) / 1,375,000 = 343,000 / 1,375,000 = 0.249 or 0.25 or 25%
(2,354,000 - 1,894,000) / 1,894,000 = 460,000 / 1,894,000 = 0.242 or 0.24 or 24%
The base number is the number of people in 2002. There is a higher percent change in number for nursing aides despite having lesser people added because its base number is lower than those in customer service. </span>
Let the number of pieces of gum be g and the cost of each piece be c.
gc=2.16. Also, (g+3)(c-0.01)=2.16.
So gc=(g+3)(c-0.01)=gc-0.01g+3c-0.03.
And -0.01g+3c=0.03 and c=2.16/g. -0.01g+6.48/g=0.03.
-0.01g²+6.48=0.03g; 0.01g²+0.03g-6.48=0 which can be more conveniently written:
g²+3g-648=0=(g+27)(g-24) so g=24, the number of pieces she actually had.
CHECK The cost of the gum, c=2.16/24=9 cents.
A penny cheaper makes the gum 8 cents a piece and she could have bought 27 pieces instead of 24.
