Answer:
x = 20
Step-by-step explanation:
The three angles make up a straight line.
A straight line has 180 degrees.
x + 3x + 100 = x80 Combine
4x + 100 = 180 Subtract 100 from both sides
4x = 180 - 100
4x = 80 Divide by 4
x = 80/4
x = 20
Answer:
The degrees of freedom associated with this problem are 16.
Step-by-step explanation:
The degrees of freedom associated with a problem, independent of the confidence level, is the sample size subtracted by 1.
In this problem, we have that:
She takes a random sample of 17 trucks, so the sample size is 17.
This means that the degrees of freedom associated with this problem are 16.
6. 150 degrees
7. 70 degrees
8. 100 degrees
Answer:
21 more days
Step-by-step explanation:
Let x be the number of days
700-112 = 28x
588 = 28x
x = 21
It will take her 21 more days
