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

Answer:
12/7
Step-by-step explanation:
5/3x+10/7=30/7
5/3x=30/7-10/7
5/3x=20/7
x=(20/7)/(5/3)
x=(20/7)(3/5)
x=60/35
simplify
x=12/7
Answer:
38
Step-by-step explanation:
Since he wants to have equal number of rows and columns..the number of plants must be a root number. 6203 is not a root number. 6241 is the closest root number
(√6241= 79)
So he needs a minimum of 6241 plants in total for it.
6241-6203= 38
Therefore he needs 38 more plants
