Answer:
3 hours 12 minutes and 5.71 seconds
Step-by-step explanation:
1. The mean of all the numbers is 41.
5. Median : 52
Answer: 11 year
P(1) = 37,100
P(4) = 58,400
The linear equation (for x ≥ 1)
P(x) = 37,100 + a(x-1)
For x = 4
58,400 = 37,100 + a(4-1)
58,400 - 37,100 = 3a
21300 = 3a
a = 7100
So, the linear equation:
P(x) = 37100 + 7100*(x-1)
P(x) = 37100 + 7100x - 7,100
P(x) = 7100x + 30000
To find when the profit should reach 108100, we can substitute P(x) by 108100.
108100 = 7100x + 30000
108100 - 30000 = 7100x
78100 = 7100x
x = 78100/7100
x = 11

Answer:
x=60
Step-by-step explanation:
I'm assuming you meant this: (x/5)-8=4
In which case you would add 8 to both sides to get rid of the 8 on the left (your goal is to get x by itself so you want to move the numbers on the x side to the other side of the equal sign)
(x/5)=12
Then you would multiply 5 on both sides to get rid of the fraction with the 5 on the bottom on the left side.
x=60
There's your answer.
