Answer:
Step-by-step explanation:
Base fee = $17.99
Additional charge = $0.95 for each mile driven
If Kevin paid $157.64 when he returned the truck and we want to find out how many miles he drove the truck, step 1 would be to subtract the base fee.
157.65 - 17.99 = 139.65
This means that the remaining $139.65 is how much he paid for the miles he drove.
Since we know each mile costs $0.95.
Simply divide $139.65 by $0.95 to work out how many miles he drove.
Miles driven = 139.65 / 0.95 = ?
Perpendicular lines have slopes that are opposite and reciprocal. Therefore, the line we are looking for has a -3 slope.
y= -3x+b
Now, we can substitute in the point given to find the intercept.
2= -3(4)+b
2= -12+b
b=14
Finally, put in everything we've found to finish the equation.
y= -3x+14

Answer:
40.1 < μ < 43.3
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
At 99% confidence and 38 degrees of freedom, CV = 2.712.
SE = s / √n
SE = 3.86 / √39
SE = 0.618
So the margin of error is:
ME = 2.712 × 0.618
ME = 1.7
So the 99% confidence interval of the population mean is:
μ = 41.7 ± 1.7
40.0 < μ < 43.4
Closest answer is the first one.
