Answer:

Therefore, she must get 5 points from the last quiz to have a mean score of 4
Step-by-step explanation:
Mean is the average of a set of data, it is the sum of the data divided by the number of data.
To have a mean of 4 from 4 quizzes;
Let x represent the total;
mean = x/4
4 = x/4
x = 4 × 4 = 16
To have a mean of 4 he must have a total score of 16.
Let y represent her score in the last quiz;
16 = 4+3+4+y
16 = 11+y
y = 16-11 = 5
Therefore, she must get 5 points from the last quiz to have a mean score of 4
Answer:
x = 9/2
Step-by-step explanation:
2(6-x)=3
Distribute
2*6 -2*x = 3
12 -2x =3
Subtract 12 from each side
12-12-2x = 3-12
-2x= -9
Divide each side by -2
-2x/-2 = -9/-2
x = 9/2
No because there are two different outputs for the same input. (9)
Answer:
-5
Step-by-step explanation:
The equation to find the slope between two points is y₂-y₁/x₂-x₁.
In this case that would be 0-20/4-0 which simplifies into -20/4=-5
So your slope is -5
