Multiply the rate per hour by the number of hours (n) and add the deposit.
A)
Bike shop x: c = 2.75n + 3.00
Bike shop z: c = 1.75n + 7.00
B) to find when they will cost the same set the equations equal to each other and solve for n:
2.75n + 3.00 = 1.75n + 7.00
Subtract 3 from each side:
2.75n = 1.75n + 4.00
Subtract 1.75n from both sides:
1.00n = 4.00
Divide both sides by 1:
n = 4 hours
I guess sides and angles !
Answer: a. statistic
Step-by-step explanation:
- Population : It is a set of all possible observations that can be made regarding a study by the researcher.
- Sample : It is finite subset of population that represents the population in the researcher's analysis.
