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
I believe the answer is B!
Hope this helped!
Answer:
(c) 
will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is 
So the slope of the line which is perpendicular to y = 3x+2 will be 
Now (a) Line is given as 
its slope is 
so it will be not perpendicular
(b) Line is given as 
its slope is so it will be not perpendicular
(c) Line is given as its slope is 
so it will be perpendicular to the line y = 3x+2
(d) Line is given as 
its slope is 3 so it will not perpendicular to the line y = 3x+2
C
Opposite / hypotenuse
Sin 45 degrees= 7/x
8•13=104
7•13=91
6•13=78
104+91+78=273
