Answer: CI = (0, 8)
Step-by-step explanation: Confidence interval for difference between mean is given below as
Lower limit
= (x1 - x2) + margin of error
Upper limit
= (x1 - x2) - margin of error
where x1 - x2 = 8 and margin of error = 8
For lower limit,
= 8 - 8 = 0
For upper limit
= 8 + 8 = 16
Hence CI = (0, 8)
Answer:
Slope is 1.5
Step-by-step explanation:
When one line has a slope of M, a perendicular line has a slope of -1/M
in this case M = -2/3, so you put it into -1/(-2/3) which equals to 1.5
Answer:
2
Step-by-step explanation:
Answer:
We have
k^2 - 25f^2 + 5kf - 25f^2 =
k^2 - (5f)^2 + 5f( k - 5f) =
( k - 5f )( k + 5f ) + 5f( k - 5f ) =
( k - 5f )( k + 5f + 5f ) =
( k - 5f )( k + 10f );
