Answer:
a) All the phones produced during the day in question.
Step-by-step explanation:
In statistics, the Population is all the objects with the same characteristics in which we have an interest in doing an experiment or statistical analysis. Sometimes to make it more simple, we take just a sample of the population and we do the experiments with them, and then the answers are used to all of the objects.
In this case, they want to analyze all the cellphones but they only take a few to do it. So the answer is a) All the phones produced during the day in question.
All you need to do is multiply 10% of 95 and you will get 9.5 and then subtract that same 9.5 off the 95 dollars and you get 85.5.
Steps:
1. Find the slope by using the slope formula
Y2-Y1
---------
X2-X1
-11 + 7
----------
-8 + 3
2.
-11 + 7= -4
-8 + 3= -5
3. Your slope is 4/5 (because you have to turn two negatives into a positive)
4. Now you do the point-slope formula
Y-Y1= m(x-x1)
Y +7=4/5 (x +3)
