Answer:
2.9661582
Step-by-step explanation:
The answer is B: The distribution for town A is symmetric, but the distribution of town B is positively skewed.
Well because in order to get a common denominator you might have to multiply a fraction to get is, doesn't change the value of the fraction it's just written with greater numbers and is not in simplest form
meaning 1/2 is the same as 8/16 one is just not simplified.
ex.
3/4+5/6
(you can't add these yet because they don't have a common denominator)
but you can make a common denominator by finding the LCM of the two denominators
fx. 4 and 6 both go into twelve, so you'd multiply the entire 3/4 fraction with 3 (because 4*3 is 12) and the entire 5/6 fraction with 2 (because 6*2 is 12)
3/4 *3 is going to give us 9/12
5/6 *2 is going to give us 10/12
now that we have the same denominator we can add the fractions together
9+10= 19. so...
19/12
We can use the points (1, 2) and (3, -4) to solve.
Slope formula: y2-y1/x2-x1
= -4-2/3-1
= -6/2
= -3
Hope This helped! Good Luck!
