Answer:
<h2>In the attachment</h2>Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the equation:
Therefore we have
the slope m = -2/3
and the point (-9, 5)
A slope
rise = -2
run = 3
From the point (-9, 5) ⇒ 2 units down and 3 units to the right.
Answer:
Mean = 1.9
Standard deviation = 0.6
Step-by-step explanation:
The Mean is calculate by the formula:
⇒
Thus Mean to the nearest tenth is 1.9
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
where, is mean of the distribution.
Putting all values in the formula, We get
Standard Deviation = 0.597 ≈ 0.6
