Hello,
Shall we begin?
227,940,000
= 2.2794 * 10^8
Answers: 2.2794 * 10^8
Answer: x=45
Step-by-step explanation:
60/120=x/90
1/2=x/90
Given that you know that x is gonna be half 90.
So 45. Then plug it in
60/120=45/90
1/2=1/2
Or do it like
60 = x
120 90
5400=120x
Then divide 120 by 5400
5400÷120=45
Answer:
(21 and 54): 3
(55 and 90): 5
(16 and 30): 2
(42 and 91): 7
(66 and 121): 11
Step-by-step explanation:
From the question we are told that:
Total Sample size n=500
Dan's mean \=x_D= 3hr
Bret's mean \=x_D= 4hr
Generally, the Total hours spent doing leisure and sports activities is mathematically given by
For Sample A


For Sample B


Therefore
Average Time spent doing leisure and sports activities by an American Adult
For Sample A




For Sample B




Therefore
Dan is Correct because 3.08 or 3.09 is approximately equal to 3
It will be A) 1/7 because using the rise over run meathod you get 1/7 and it will be possitive
