<span>This is a value that cannot be determined at current (choice D). The z-score associated with the mean is 0, but the median value is not always equal to the mean. In this case, it could be 0, it could be greater than 0, or it could be less than 0.</span>
Answer:
y = 9/4x
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (-9-0)/(-4-0)
= -9/-4
=9/4
We know the y intercept is 0 since it goes through the origin
We can use the slope intercept form of the equation
y = mx+b
y = 9/4 x +0
y = 9/4x
Answer:
No
Step-by-step explanation:
5(3+2) = 5(5) = 25
5.3 + 5.2 = 10.5
25 doesn't equal 10.5 therefore 5(3+2) isn't equivalent to 5.3 + 5.2

Answer:
Step-by-step explanation:
If we let x represent one of the numbers, then you want ...
x(58 -x) = 201.25
x² -58x +201.25 = 0 . . . . . put in standard form
(x² -58x +29²) +201.25 -29² = 0 . . . . complete the square
(x -29)² -639.75 = 0
x -29 = ±√639.75 . . . . . add 639.75 and take the square root
x = 29 ±√639.75 . . . . . . add 29
The two numbers of interest are ...
29 +√639.75 ≈ 54.2933
29 -√639.75 ≈ 3.7067
