Answer:
Step-by-step explanation:
we know that
The <u>distance formula</u> is derived by creating a triangle and using the Pythagorean theorem to find the length of the hypotenuse. The hypotenuse of the triangle is the distance between the two points
The formula to calculate the distance between two points is equal to
we have
A(1, 1) and B(7, −7)
Let
(x1,y1)=A(1, 1)
(x2,y2)=B(7, −7)
substitute the given values in the formula
54/8 = 6 6/8 . . . . . the 1st selection is appropriate
Answer:
well first i need the shape
Step-by-step explanation:
Answer:
90% Confidence interval: (8463.1,8528.9)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 8496 lb
Sample size, n = 125
Alpha, α = 0.10
Population standard deviation, σ = 100
90% Confidence interval:
Putting the values, we get,
This has exactly two solutions.
You can find the number of a solutions that a problem has by its highest power of x. Since x is raised to the 2nd power in here, it has two solutions. In some cases, these solutions will be irrational, double roots, or non-real, but there will still be two of them regardless.
