Answer:
Step-by-step explanation:
Let h represent the number of hours that Jamarcus can rent the truck.
To rent a truck, the charge is $16 per hour and also a fueling fee of $25
The total cost of renting the truck for x hours would be
16h + 25
Since Jamarcus wants to rent the truck and can spend no more than $125, the inequality representing the situation would be
16h + 25 ≤ 125
16h ≤ 125 - 25
16h ≤ 100
h ≤ 6.25
2) 3x - 5 ≥ - 11
3x ≥ - 11 + 5
3x ≥ - 6
x ≥ - 6/3
x ≥ - 2

Answer:
A. T > 2.539
Step-by-step explanation:
We have a hypothesis test of the mean, with unknown population standard deviation.
The hypothesis are:

From the hypothesis we can see that the test is right-tailed, so the critical value of t should be a positive value.
The degrees of freedom can be calculated as:

The significance level is 0.01, so the critical value tc should be the one that satisfies:

Looking up in a t-table, for 19 degrees of freedom, this critical value is tc=2.539.
