Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 138
Average = 32.6 inch
Population variance,
We have to find a point estimate for the population variance of the height.
The point estimate for the population variance is the population variance itself.
Thus, the point estimate of population variance is the population variance that is 2.8.
Answer: do 2.1 times 100 than that answer times 0.6

Answer:
430
Step-by-step explanation:
761-331=430
Did you notice the little box with corners marked in the angle down at the bottom ?
That angle is a right angle, and <em>this triangle is a right triangle</em> !
This piece of information is a big help. It breaks the problem wide open.
You know that in order to find the longest side of a right triangle . . .
-- Square the length of one short side.
-- Square the length of the other short side.
-- Add the two squares together.
-- Take the square root of the sum.
One short side=48. Its square = 2,304.
The other short side=48. Its square = 2,304.
Add the two squares: 2,304 + 2,304 = 4,608
The square root of the sum = √4,608 = <em><u>67.88</u></em> (rounded)
Answer:
Step-by-step explanation:
Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.
