$37.25 must be payed for the total time of 115 minutes.
<u>Step-by-step explanation:</u>
- The cost for 1st 45 minutes = $12.75
- The cost per minute for additional 2 hours = $0.35
- The cost per minute for additional time after 2 hours = $0.25
x be the total time spent in minutes,
It is given that the total time spent, x = 115 minutes.
<u>To find the cost to pay for 115 minutes :</u>
The first 45 minutes out of 115 minutes should be payed $12.75
Therefore, the remaining minutes is 115 - 45 = 70 minutes.
The additional 2 hours (120 minutes) should be payed $0.35 per minutes.
But, in this case the additional time is only 70 minutes.
⇒ 70 × 0.35
⇒ $24.5
The total amount to be payed for 115 minutes = $12.75 + $24.5
⇒ $37.25
10m + -0.4 = 9.6
-0.4 + 10m = 9.6
-0.4 + 10m = 9.6
Solving for 'm'Move all terms containing m to the left, all other terms to the right.
-0.4 + 0.4 + 10m = 9.6 + 0.4
Combine like terms: -0.4 + 0.4 = 0.00.0 + 10m = 9.6 + 0.410m = 9.6 + 0.4
Combine like terms: 9.6 + 0.4 = 1010m = 10
Divide each side by '10'.<span>m = 1</span>
Answer:
D) the standard error for her sample is 15
Step-by-step explanation:
Samantha is 95% certain that between 50% and 70% of the first year students agree that they should be able to bring a car to campus.
Here
- 95% is the confidence level.
- The range between 50% and 70% indicates 95% confidence interval.
- 60% is the average proportion of the first year students at her university think they should be able to bring a car to campus.
- 10% (0.1) is the margin of error from the mean
Since standard error can be obtained by dividing margin of error by the z-statistic of the confidence level which is 1.96. The standard error for her sample 
does not equal to 15.
