Answer:
1 + 1 = 2, if you are doing multiplication then it is 1 x 1 = 1
Step-by-step explanation:
Answer: Choice C) Undefined slope is when there is no vertical change
If you replace "vertical" with "horizontal", then choice C would be a true statement. All vertical lines have an undefined slope.
This is because the slope formula
m = (y2-y1)/(x2-x1)
has 0 in the denominator when you subtract the x coordinates. Dividing by zero is undefined. For any single vertical line, the x coordinates of any two points are the same. For instance, the vertical line through 4 on the x axis is the equation x = 4, and every point on this line has x coordinate 4.
solution:
If U=W-(54.5/6) then W=U+(54.5/6).
Assuming a one-for-one transformation, the mean for W is found by adding all the W data together then dividing by 79.
That is, Wbar=(w1+w2+w3+...+w79)/79.
But w1=u1+54.5/6, w2=u2+54.5/6, etc.
So Wbar=(u1+u2+...+u79)/79+(79×54.5/6)/79=Ubar+54.5/6=6.8+54.5/6=15.8833 approx.
The variance is unaffected by the transformation since variance is simply the spread of the data which doesn’t change.
Wbar=Ubar=1.8.
