Answer:
1.734
Step-by-step explanation:
Given that:
A local trucking company fitted a regression to relate the travel time (days) of its shipments as a function of the distance traveled (miles).
The fitted regression is Time = −7.126 + .0214 Distance
Based on a sample size n = 20
And an Estimated standard error of the slope = 0.0053
the critical value for a right-tailed test to see if the slope is positive, using ∝ = 0.05 can be computed as follows:
Let's determine the degree of freedom df = n - 1
the degree of freedom df = 20 - 2
the degree of freedom df = 18
At the level of significance ∝ = 0.05 and degree of freedom df = 18
For a right tailed test t, the critical value from the t table is :
1.734
The correct answer is choice B. When you are multiplying anything by a value greater than one, the answer you get will always be bigger than what you started with.
The reason lies with in the concept of multiplication.
If you have more than one group of something, you will have more than what you started with.
Answer: 2c + 2 = 16
Step-by-step explanation:
One group has 2 more than the other.
That means in total, they are the same but + 2.
Only 2c + 2 = 16 represents this.
Answer:
444 thumb drives
Step-by-step explanation:
Break even is the point at which the proceeds are equal to the costs i.e. when Total cost = Total revenue. So using the equations provided, the breakeven point for Burnem Inc. will be 4x + 4884 = 15x, where x is number of thumb drives. We solve for x to get the answer:
4x + 4884 = 15x
4884 = 15x - 4x
4884 = 11x
x = 4884/11
x = 444 thumb drives
