Answer:
D
Step-by-step explanation:
I usually use a z-score table, but you can do this with a calculator.
If we go to a z-score table, we first look up the first two digits (in this case, 2.8) in the far left column. Then we find the hundredths digit in the top row (0.07). Where they intersect is P(z < 2.87).
P(z < 2.87) = 0.9979
Answer D.
Answer:
5
Step-by-step explanation:
If you multiply the square root of any number by the square root of the same number you get that number.
Answer: I=sqrt(P/R)
Step-by-step explanation:
R=p/I^2
Multiple l squared on both sides...
(I^2) R=p/l^2 (l^2)
R(I^2)=p
Separate I by dividing both sides by R...
I^2=p/R
Square root both sides...
I=sqrt(P/R)
The answer would be 480 and because you multiply 30 times 12 you will get 360 and then you add that to the money he already has which is 120 so the total amount is 480
