Answer:
Kayla plays on average 0.2 more chess games than Becker
Step-by-step explanation:
The first thing we must do is calculate the mean of each one.
Becker:
(5 + 2 + 4 + 1 + 1 + 4 + 5 + 3 + 2 + 1) / 10 = 2.8
Kayla:
(2 + 3 + 1 + 1 + 4 + 1 + 5 + 3 + 5 + 5) / 10 = 3
if we subtract these averages, we have to:
3 - 2.8 = 0.2
which means that Kayla plays on average 0.2 more chess games than Becker. Since it is not even a complete game, the difference between the two is very small and almost irrelevant.
She walks 3 mph because when you divide it by 2 it will equal
3 miles in 1 hour
5x/2 = 10/11
55x = 20
x = 4/11

Answer:
9.80
Step-by-step explanation:
Given that a survey of sports fan was conducted counting no of persons whose favourite was football, baseball, basketball and hockey.
Given that 49 like football, 35 baseball, 11 basket ball and 5 hockey
We have to find ratio of football fans to hockey fans.
We find that hockey fans are 5 and football fans are 49
Ratio of football fans to hockey fans =49/5
=9.80
The ratio means if 9.80 football favourite persons are there there would be only one person whose favourite is hockey.
It opens down if the lead coefficient is negative
And it shifts to the left by two. Always use the opposite of what is in parenthesis, which in this case is 2.
