Answer: About 8.5 cubic yards
Step-by-step explanation:
Given : The length of the garden = 16 ft.
The width of the garden = 34 ft.
The depth of the thick layer of topsoil on the garden = 5 inch
=
[Since 1 foot = 12 inches]
The volume of a rectangular prism :-
, where l is length , w is width and h is height.
The number of cubic feet of topsoil required will be
Since 1 yard = 3 feet

Answer:
Mean = 2.7
In a group of 74090 we would expect about 3 (rounding to nearest whole number) children with the rare form of cancer.
Step-by-step explanation:
We are given that the rate of cancer in children is 37 children in 1 million. So the probability of cancer in a child is P(C) = 0.000037
Poisson distribution is used to approximate the number of cases of diseases and we have to find what will be the mean number of cases for 74,090.
In simple words we have to find the expected number of children with cancer in a group of 74,090 children.
The mean value of expected value can be obtained by multiplying the probability with the sample size. So, in this case multiplying probability of child having a cancer with total group size will give us the expected or mean number of children in the group with cancer.
Mean = E(x) = P(C) * Group size
Mean = 0.000037 x 74090
Mean = 2.7
This means in a group of 74090 we would expect about 3 (rounding to nearest whole number) children with the rare form of cancer.
Answer:
3:02pm
Step-by-step explanation:
we can first do 450/56 to find out how long it takes the train to travel 450 miles
this equals 8.0357142857
so this is 8 hours plus a little more time
we now have to convert that decimal into a number of minutes
60(0.0357142857)
that equals 2.142857142
so that's 2 minutes and 14 seconds
so we just need to add 8 hours 2 minutes and 14 seconds to 7:00am
which would be 3:02:14pm
13.2*3=39.6= price of 3cds, which is also the price of 2 dvds
39.6/2=19.8= the price of 1 dvd
