Answer:
0.06597
Step-by-step explanation:
Given that thirty-seven percent of the American population has blood type O+
Five Americans are tested for blood group.
Assuming these five Americans are not related, we can say that each person is independent of the other to have O+ blood group.
Also probability of any one having this blood group = p = 0.37
So X no of Americans out of five who were having this blood group is binomial with p =0.37 and n =5
Required probability
=The probability that at least four of the next five Americans tested will have blood type O+
= 
Tanα=h/x
h=xtanα, we are told that x=6.5ft and α=74° so
h=6.5tan74 ft
h≈22.67 ft (to nearest hundredth of a foot)

Correct option is A. Money saved is ′ $6 ′ .
Given
Regular price of the refrigerator = $600
i) Buying the refrigerator at 20 percent off regular price
Final Discount in this case = 20% (Regular price of the refrigerator)
= 20 / 100 × 600
= $120
ii) Buying it on sale at 10 percent off regular price and an additional 10 percent off sale price
Discount for the sale = 10% (Regular price of the refrigerator)
= 10/100 × $600
= $60
Sale price of the refrigerator = Regular price of the refrigerator − Discount for sale
= $600 − $60
= $540
Final Discount in this case = 10% (Sale price of the refrigerator)
= 10/100 × $540
= $54
Money saved if we buy as (case−i) = (Final Discount in (case.i)) − (Final Discount in (case.ii))
= $60 − $54
= $6
Therefore, Money saved is ′ $6 ′ .
