Find the probability that the account has a balance at least $500, given that it is at least 3 years old.
Which means: P(≥$500 | ≥3 years)
To find the probability, use the formula below:
P(≥$500 | ≥3 years) = (No. of accounts with balance≥ 500 and age ≥3 years) / (No. of accounts with age≥3 years)
Where from th given information:
Number of accounts with balance≥ 500 and age ≥3 years = 200
Number of accounts with age≥3 years = 600 + 200 = 800
Therefore,
P(≥$500 | ≥3 years)
The probability that the account has a balance at least $500, given that it is at least 3 years old =
Answer:
121 sq. in
Step-by-step explanation:
area of the frame = 48 square inches
if is the side length of the square, then (
+ 2) is the side length of the square after the frame has been added.
the area of the picture + the frame is:
( + 2) (
+ 2)
the area of just the frame is given by ( + 2) (
+ 2) -
x
:
( + 2) (
+ 2) -
x
=48
²+
x 2 + 2 x
+ 2 x 2-
² = 48
² + 2
+ 2
+ 4-
² = 48
4 + 4 = 48
then subtract 4 from both sides:
4x = 44
and divide both sides by 4:
x = 11
the area of the square is 11 (11) = 121.
i think this is correct?
hope this helps :))
