Answer:
Sleep well
Step-by-step explanation:
To obtain an overall average of 86%, a score of 96 is required on her 4th test.
Let the required score on her fourth test = t
The required average = 86%
Initial scores : 80% + 83.5% + 84.5%
Average = ΣX/ (fx)
fx = total score obtainable = 4 × 100 = 400
ΣX = sum of scores
Average = 86%
0.86 = ((80 + 83.5 + 84.5 + t) / 400)
86 = (248 + t) / 400
400 × 0.86 = 248 + t
344 = 248 + t
344 - 248 = t
96 = t
In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

Answer:
y=1/2x+5/2
Step-by-step explanation:
4-3=1
3-1=2
m=1/2x
So now you have y=1/2x
Insert into equation
y=1/2x+?
Now sub you slope in to last points, and you get 5/2
So now you final answer is:
y=1/2x+5/2
