Answer:6,1
Step-by-step explanation:
Answer:
The slope is 2.
Step-by-step explanation:
The given line has equation: 
.
This is a linear equation in 
.
The slope is the coefficient of the independent variable .
The coefficient of in is 2.
Therefore the slope is 2.
Alternatively, is of the form 
, where 
is the slope.
Answer:
r=1
Step-by-step explanation:
-7.61 - 4.3r = -8.1r - 3.81
(bring like terms to one side)
-4.3 r = -8.1r -3.81 + 7.61
-4.3r + 8.1 r =-3.81 + 7.61
(consolodate)
3.8r = 3.8
(divide right by # of r)
r = 3.8/3.8
r = 1
Answer:
Mean = 0.4
Stand deviation = 0.08944
Step-by-step explanation:
1.
This question tells us that the mean of trapped moths is only 0.4
Therefore the mean = E(X) = 0.4
2.
The standard deviation of the sample mean is
= σ/√n
σ = 0.6
n = 45
When we put these values into the formula we will have:
0.6/√45
= 0.6/6.708
= 0.08944
So in conclusion, the mean is 0.4 and the standard deviation is 0.08944.
Thank you!
You are trying to isolate x, so you would first subtract the y and get ax-bx= z-y
then you would divide by a-b
giving you A as the answer
