Answer:

To find part A you need to find common denominator.

1/3 + 3/5=

5/15 + 9/15= 14/15

His mistake for a is that he didn't find the common denominator and that he just added the fraction as it is. So the corrected version would be 14/15.

To find part B you also need to find the least common denominator.

11/12-5/6=

11/12-10/12=1/12

His mistake was that he didn't find the least common denominator and he subtracted the fraction as it is. The answer corrected would be 1/12.

PLEASE HELP
Kitty [74]

Answer:

542.50

Step-by-step explanation:

Given:

Least square regression equation :

y = 102.50 + 0.65x + residual

y = predicted fare

x = distance in miles

Intercept = 102.50

Slope = 0.65

Distance in miles, x = 500 miles

y = 102.50 + 0.65(500) + 115

y = 102.50 + 325 + 115

y = 427.5 + 115

y = 542.50
