Mathew wants to rent a jet ski for a day. it will cost him $125 per hour plus a $10 fee for a life jacket. let h = the number of hours mathew rents the jet ski. write an expression that shows the total amount he will pay. h + part b evaluate the expression you wrote to find the amount mathew will pay if he rents the jet ski for 3 hours. $
Answer: A. 125h + 10 B. $385
Step-by-step explanation:
let h = the number of hours Mathew rents the jet ski
a. 125h + 10
B. Plug in 3 for h
125(3) + 10
375 + 10
⇒ $385
Answer:
F(h)= 125h+10
F(3)=125(3)+10
F(3)=375+10
F(3)=385

Below are the data collected from two random samples of 500 American adults on the number of hours they spend doing leisure and sports activities per day (rounded to the nearest hour):
Number of hours spent doing leisure and sports activities per day 1 2 3 4 5
Sample A: Number of adults 70 90 135 140 65
Sample B: Number of adults 80 80 130 135 75
Dan concludes that adults spend a mean of 3 hours each day doing leisure and sports activities. Bret thinks the mean is 4 hours. Who is correct—Dan or Bret? Explain your answer in two or three sentences. Make sure to use facts to support your answer.
Answer:
Dan is correct
Step-by-step explanation:
Mean = the sum of all data values divided by the total number of data values
Number of adults in Sample A:
= 70 + 90 + 135 + 140 + 65 = 500
Mean of Sample A:
= [ (1 × 70) + (2 × 90) + (3 × 135) + (4 × 140) + (5 × 65) ] ÷ 500
= 1540 ÷ 500
= 3.08
Number of adults in Sample B:
= 80 + 80 + 130 + 135 + 75 = 500
Mean of Sample A:
= [ (1 × 80) + (2 × 80) + (3 × 130) + (4 × 135) + (5 × 75) ] ÷ 500
= 1545 ÷ 500
= 3.09
Mean of the two samples:
= (3.08 + 3.09) ÷ 2
= 3.085 hours
= 3 hours (nearest hour)
The mean of Sample A is 3.08 hours and the mean of Sample B is 3.09 hours, so the mean of the entire sample is 3.085 hours. If we round this to the nearest hour, then the mean is 3 hours. Therefore, Dan is correct in concluding that the adults spend a mean of 3 hours each day doing leisure and sports activities.
What is the quotient of 1.728 x 109 and 4.8 x 106 expressed in scientific notation?
Answer:
4.1386 X 10^3
Step-by-step explanation:
since,
1.728 x 109 = 187 .48

By evaluating, we will see that for x = 7 h(x) exceeds g(x).
For which value of x does h(x) first exceed g(x)?
We have:
h(x) = 2*(2)^x
g(x) = 22x - 4
Now we can evaluate both function in the different options:
h(5) = 2*(2)^5 = 64
g(5) = 22*5 - 4 = 106
We can see that for x = 5, h(x) does not exceed g(x), let's try the next one.
h(6) = 2*(2)^6 = 128
g(6) = 22*6 - 4 = 128
So, for x = 6 both functions have the same output, then for x = 7 we will see that h(x) exceeds g(x).
The correct option is B.
