Answer: 105 chocolate bars
Step-by-step explanation:
The equation for this problem would be a=97-4*2
So, 97-4=93, and 4 * 2=8 so 93+8= 101
So he had 101 chocolate bars at first.
Given the equation :

We will use estimation to find the value of the given expression
So, the best estimation for the number 576 is = 600
The best estimation for the number 8 is = 10
So, the given expression is approximately = 600 ÷ 10 = 60
===================================================================
We can calculate the error of the approximation as following :
The actual value is : 576 ÷ 8 = 72
So, the difference is = 72 - 60 = 12
so, the percentage of error will be :

Answer:
(0.1,1.1)
Step-by-step explanation:
we have


Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (0.081,1.093)

Answer:
mean absolute deviation
Step-by-step explanation:
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
