Answer:
0.92
Step-by-step explanation:
a. What is the probability that at least one of the stocks will rise in price? (Round your answer to 2 decimal places.)
P(A) = 0.42
P(B) = 0.58
P(A|B) = 0.14
Step 1
P(A|B) × P(B) = 0.14 × 0.58
= 0.0812
The probability that at least one of the stocks will rise in price
P(A) + P(B) - 0.0812
0.42 + 0.58 - 0.0812
= 1 - 0.0812
= 0.9188
Approximately to 2 decimal place = 0.92
Because y varies inversely as x, therefore
where k = constant.
When x = 6, y = 2.5. Ther efore
Cross multiply.
k = 6 x 2.5 = 15
The equation is
When x = 4, obtain
