Answer:There is a relationship between study hours and test score. As the hours of studying increase, the test scores increase.
Step-by-step explanation:
From the given scatterplot in which Mackenzie investigated the relationship between the number of hours studying and the test score for some of the students in her class.
We can see that the dots are increasing in the right and go upward with respect to time.
It shows there is a relationship between the test score and hours of studying.
As the hours of studying increase, the test scores increase .
Answer:
z = 5*(1/2)
z = 5/10

time switching classes:
w = 7/10
---
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (76/10 - 5/10 - 7/10)/6
x = (76 - 5 - 7)/(10*6)
x = (64)/(10*6)
x = (2*2*2*2*2*2)/(2*5*2*3)
x = (2*2*2*2)/(5*3)
x = 16/15
x = 1.0666666666

check:
y = 7 + 3/5
y = 7.6
z = 1/2
z = 0.5
w = 7/10
w = 0.7
y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (7.6 - 0.5 - 0.7)/6
x = 1.0666666666

10 × 12 / 6 = 20
Answer:
A
Step-by-step explanation:
On edge
It takes 8 hours to clean 12 houses so that’s 8/12 to find how many hours it take to clean one house, 8/12 is equal 2/3 . So it takes 2/3 of an hour to clean one house. 2/3 times 12 equals 8. So you want to find how many houses you can clean in 12 hours. The equation is 12= 2/3x , x=18. The answer is 18 houses. Check the work cus I sure didn’t lol, hope this helps
