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
If an equation has the same slope it will always be parallel so which y=1/2x-1 then y=1/2x+2
Answer:
Step-by-step explanation:
Given:
The ratio is:
1.5 kg : 350 g
To find:
The lowest or simplest form of the given ratio.
Solution:
We know that,
1 kg = 1000 g
We have,
1.5 kg : 350 g
It can be written as
Therefore, the lowest form of the given ratio is 30:7.
Step-by-step explanation:
3/4x+3-2x=1/4+1/2x+5
x=2/-3
