Answer:
y=8/7x+5/7
Step-by-step explanation:
Answer:
Answer is - 2.
Step-by-step explanation:
(f+g) (x)=f(x) +g(x)=x^2 -2x +6x+4
=x^2 +4x+4=0
If x=-4, then (f+g) (-4) =16-16+4=4
if x=-2, then (f+g) (-2)=4-8+4=0
Answer:
the standard error is 153.125
Step-by-step explanation:
given that
The random sample is 256
The sample mean is $35,420
And, the standard deviation is $2,450
We need to find out the standard error
We know that
= standard deviation ÷ √random sample
= 2450 ÷ √256
= 2450 ÷ 16
= 153.125
Hence, the standard error is 153.125
Answer:
Not a function because there are two values of y for x = -8.
Basically, it's -4+6, which is 2. SO, the temperature at noon on Tuesday was 2 ºF.
