Answer:
B. 9.6 = the number of points you would increase each hour of studying;
65.8 = your score if you studied 0 hours
Step-by-step explanation:
A linear regression equation y = 9.6x + 65.8, with x representing hours.
When x = 0, then y = 65.8. This means
65.8 = your score if you studied 0 hours
When x = 1, then
is your score after studying one hour.
The score increased by 
so
9.6 = the number of points you would increase each hour of studying.
Answer:
(8s + 22) ≤ 60
Step-by-step explanation:
Let the number of shirts Florencia bought = s
Cost of one shirt = $8
Therefore, total cost of the 's' shirts= $8s
She bought a jeans for $22 and rest amount she spent on shirts.
Total expenditure = $(8s + 22)
Since, she can not exceed her expenditure beyond $60.
So the inequality will be,
(8s + 22) ≤ 60
Π*√9
π*3
3π π ≈ 3.1416
3*3.1416
≈ 9.4248
Hope this explains it.
Answer:
20
Step-by-step explanation:
set up equation
13/x=65/100
cross multiple: 1300=65x
divide 1300/65=20
