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!
Answer:
47,100.00
Step-by-step explanation:
(2,2)(-2,-4)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2. the slope of this line is 3/2. A parallel line will have the same slope
y - y1 = m(x - x1)
slope(m) = 3/2
(-3,1)...x1 = -3 and y1 = 1
now we sub
y - 1 = 3/2(x - (-3)....not done yet
y - 1 = 3/2(x + 3) <=== its the last one
You can set it up as an equation:
29.95x + 2x
then plug in x = 7.
I'm not sure how this really relates to the distributive property though.
The y intercept is 3 because the line intercepts the y axis at 3.
:D
