Answer: Mike's arm span is 7.165 cm longer than the George's one.
Step-by-step explanation:
We have that the association between height and arm span is modeled by the equation
y = 4.5 + 0.977*x
where y is height and x is arm span.
Mike is 172 cm tall, so his arm span is:
172cm = 4.5 + 0.977*x
x = (172 - 4.5)/0.977 = 171.443 cm
and George is 165 cm tall, so his arm span is:
x = (165 - 4.5)/0.977 = 164.278 cm
Then the difference between their arm span is:
171.443cm - 164.278cm = 7.165 cm
So Mike's arm span is 7.165 cm longer than the George's one.
By adding/ subtraction systems
Answer:
11
Step-by-step explanation:
divide 209 by 19 to get an equal number of games each month (for 19 months), you will get 11 games each month.
Number 10 is Answer: y=2.5/2x+3.5
Step-by-step explanation:
The 3.5 is the y intercept because it is when x is 0. The slope is just the change in y over the change in x
