Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.
Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.
Answer:
Slope: 1
Step-by-step explanation:
In this question, we need to find the slope with the given points.
To find the slope, we would use the equation:
m = y2-y1/x2-x1
Plug in your coordinates and solve:
m = 0 - 7/-2 - 5
m = -7/-7
Two negatives cancel each other to make a positive, and 7/7 = 1
m = 1
This means that the slope would be 1.
