Answer:
n(B U S) = 75
Step-by-step explanation:
P(E) =
Let 'B' be the event of having twelve year old brother
Let 'S' be the event of having twelve year old sister
given data P(BUS) = 0.25
given total survey n(survey) = 300
we have to find the value is n(BUS) =?
we will use probability definition we get, P( BUS) =
substitute given values, we will get solution
after cross multiplication , we get
n(BUS) = 0.25 X 300
n(BUS) = 75
Answer:
x = -2 to x = 1
Step-by-step explanation:
A function is constant when the y value does not change (i.e. the graph is a horizontal line). This is true between x = -2 and x = 1.
The third side is 84 inches long, therefore it has to be the hypotenuse because it's the longest side.
Answer:
m=217 miles/31 days
Step-by-step explanation:
Carl has to run 217 miles in 31 days; to find the number of miles
he needs to run per day, he should divide the number of miles he has to run (217 miles ) by the number to days he will run ( 31 days):


Carl has to run 7 miles per day. We can confirm this result by multiplying this by 31 days, and we should get 217 miles:
