The purpose of the confidence interval is to give a range of where the true value of a parameter lies given a confidence level.
Look at the slope in each equation. A neg. slope indicates that the function is decreasing. A pos. slope: increasing.
Answer: the number of possible values of a are 3 and 6
Explanation:
Since a is a divisor of 12
Then let’s see what are the divisor for 12
12= 6 x 2
12= 3 x 4
And we know that 3 is a factor of a
So if a was 3 then 3/3 is exactly 1
And if a was 6 then 6/3 is exactly 2 with no remainder
And 3 and 6 are also the divisor of 12
12/6=2
12/3=4
So a should be 3 and 6
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by 2 and get
x=7
