Answer:
57.142%
Step-by-step explanation:
28-12=16
16/28*100=57.142%
The limit does not exist. Why? Because the left hand limit DOES NOT equal the right hand limit. Let’s double check:
We could use -0.000001 to represent the left hand limit. This is less than 0. We plug in 5x - 8
5(-0.000001) - 8
-0.000005 - 8
-8.000005
If we would continue the limit (extend the zeros to infinity), we would get exactly
-8
That is our left hand limit.
Our right hand limit will be represented by 0.000001. This is greater than 0. We plug in abs(-4 - x)
abs(-4 - (0.000001))
abs(-4.000001)
4.000001
If we would continue the limit (extend the zeros to infinity), we would get exactly
4
4 does not equal -8, therefore
The limit does not exist

Ther perccent error in her estimate is 15%
Answer:
25%
Step-by-step explanation:
Height of all the bars in chart = 2 or more is 10, 3, 1.
Add all the bars to give us exact amount of data required = 10 + 3 + 1 = 14
Total number of students in class = 56
Percentage of class having two or more student = (14/56) * 100% = 25%
With the information given it should be 10.
4x+ 5= 45
-5. -5
4x=40
x=10
