In the formula d=/(x2-x1)^2+(y2-y1)^2 , how does each subtraction expression relate to the Pythagorean theorem?
2 answers:
Answer:
option A
Step-by-stevvp explanation:
In the formula
The formula is used to find the distance between two points
(x2-x1) gives the length of one leg
(y2-y1) gives the length of another leg
In a right angle triangle , Pythagorean theorem is
where a and b represents the sides of the triangle
Each subtraction expression in the formula represents the leg of the right angle triangle with the hypotenuse of length d

Obviously, 12.800 <u>< </u>12.815.
Answer:
critical value = 5.29
Step-by-step explanation:
Given that they are divided into 4 groups and a sample of 5 test was selected
N = 5 * 4 = 20
k = 4
∝ = 0.01
Df for numerator ( SS group )= k - 1 = 3
Df for denominator ( SSE group ) = N - k = 20 - 4 = 16
DF ( degree of freedom )
Next we will use the F table to determine the critical value
Critical value = = 5.29
