Step-by-step explanation: Answer: around 64 minutes
We need to first set the two equal to each other.
We can model the first part using the slope intercept form.
y=.17x+15
We are trying to find the amount of minutes or x she can spend. We solve for x by using inverse operations.
However, the question states that she has already paid the flat fee of 15 dollars, so we are only doing .17x=10.92 (inverse operations for x)
X=64.23 minutes or around that.
Here are the first 3 to show you how to do them
Answer:
2
Step-by-step explanation:
10/3 times 6 =20
1/4 (20) -3
Use PEMDAS
1/4 (20) is 5
5-3=2
Answer:
Cluster
Step-by-step explanation:
According to the Question,
- Given this, Daimler−Chrysler randomly selects 100 service centers during a certain week and surveys all customers visiting the service centers.
This is a Cluster type of Sampling.
- Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population cluster. The analysis of such a population is carried out based on the sampled clusters.
- This method is adopted when a researcher does not have access to the whole population under research.
Advantages of cluster sampling
- The research method only needs fewer resources.
- The sample under review is feasible.
Note: Cluster sampling is not as accurate as simple or stratified random sampling.
Ok so
8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug
profit=R20m-R8000
where m=number of mugs sold
(R20 means 20 rand)
f(m)=R20m-R8000
break even means cost=earned
basically, when profit=0
0=R20m-R8000
add 8000 to both sides
R8000=R20m
divide both sides by 20
400=m
break even is 400 mugs
graph should be easy enough
put a point at (0,-8000) and at (400,0) then connect them
profit
f(x)=R20x-R8000
break even is 400 mugs
put points (0,-8000) and (400,0) and connect them
