Answer:
(a) = 40%
(b) = 28%
(c) Expected value = $222,500
Standard deviation = $7,216.88
Step-by-step explanation:
This is a normal distribution with a = 210,000 and b =235,000
(a) The probability that he will get at least $225,000 for the house is:
(b)The probability he will get less than $217,000 is:
(c) The expected value (E) and the standard deviation (S) are:
42 - ( 42÷2 + 10 ) = 42 - ( 21 + 10 ) = 42 - 31 = 11 cars are silver ;
11 / 42 is the fraction of the cars are silver.
Well 3/4=0.75 and then 0.75 times 8 = 6! So your answer is 6!
Answer-180cm3
Explanation-
The volume of a prism is base x height so v=bh
Here the base equals 4cm times 15m which gives 60cm.And then the height is 3cm.So the total is 15cmx4cmx3cm=180cm³
