you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
You would round 1.049 to 1.05.
P(A) means "Probability of Event A" The complement is shown by a little mark after the letter such as A' (or sometimes Ac or A): P(A') means "Probability of the complement of Event A" The two probabilities always add to 1.
The answer is 1954. Letter C is correct
Solution:
If P(x) = <span>165,000
</span>Then
165,000 = 55,000(x - 1945<span>)^(1/2)
x= 1954
to check it, substitute x
</span>165,000 = 55,000(1954 - 1945)^(1/2)
165,000 =165,000
