FOR A TEST A set of nine cards has a different number, 1 through 9, printed on each card. Sarah picks one card from the set, replaces it, and then draws a second card. What is the probability that Sarah draws a 3 and then draws a multiple of 2?

4/81

Step-by-step explanation:

So first, the probability that she gets a 3 first is 1/9, because there is only 1 card out of 9 total cards.

Next, the probability that she gets a multiple of 2 is 4/9, because there are 4 different things she can pick (2, 4, 6, 8) out of the total 9 cards.

The last step is to multiply the two, so 1/9 * 4/9 = 4/81.

third choice down

step-by-step explanation:

the first inequality is based on the number of adults and campers, and the second inequality is based on the cost of feeding both the adult and the camper.

we know that there is room for 525 people max.   it's ok to have less than 525, but it's not ok to have more than 525, so the inequality is less than or equal to.   the number combination of adults (x) and campers (y) cannot exceed this 525 max.   therefore:

x + y ≤ 525

now we talk about cost.   it costs $9 to feed one adult, so depending upon the number of adults you have (x) depends upon how much it will cost to feed that number of adults.   same with the campers, who cost $5 to feed.   the adults can be represented by 9x and the campers can be represented by 5y.   since the budget cannot exceed 1,200, the second inequality is:

9x + 5y ≤ 1200
