2/4 + 18/5 + 28/10 + 5/20 = 143/20 (total)
143/20 ÷ 4 = 1 63/80
Ans: 1 63/80 or 1.7875

72 cards per stack, which makes for 6 baseball stacks, and 5 football stacks

M=2
Then you plug in a point to find b
1=2(1)+b
1=2+b
-1=b
y=2x-1
x*(1.035) + (4,200-x)*(1.045) = 4,374.00
1.035x + 4,389.00 -1.045x = 4,374.00
15.00 = .01x
x = 1,500 so x (1,500) invested at 3.5% and
(4,200 - 1,500) (or 2,700) invested at 4.5%
Need to develop a contingency table (often used for calculating probabilities when the focus is on conditional probability).
The nurse is either M or F.
The nurse either has a BS degree or does not.
Since there are 125 female nurses, and 56 of those held bachelors degrees, that leaves (125-56), or 69, who did not hold bachelors degrees. Complete this table. I found that there are 75 male nurses and 125 female nurses. Note that 75 and 125 add up to 200 (which is the given number of nurses).
