Step-by-step explanation:
The formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D
<h3>Equation</h3>
- Number of tires needed by each car = 4
- Number of spare tires needed by each car = 1
Total tires needed by each car = 4 + 1
= 5
- Number of cars produced per day = c
Total number of tires, t needed for c cars.
Number of tires needed, t = Total tires needed by each car × Number of cars produced per day
t = 5 × c
t = 5c
For instance,
if 5 cars are produced per day
Number of tires needed, t = Total tires needed by each car × Number of cars produced per day
t = 5c
= 5 × 5
t = 25 tires
Therefore, the formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D

Answer:
Standard Deviation = 5.928
Step-by-step explanation:
a) Data:
Days Hours spent (Mean - Hour)²
1 5 61.356
2 7 34.024
3 11 3.360
4 14 1.362
5 18 26.698
6 22 84.034
6 days 77 hours, 210.834
mean
77/6 = 12.833 and 210.83/6 = 35.139
Therefore, the square root of 35.139 = 5.928
b) The standard deviation of 5.928 shows how the hours students spend outside of class on class work varies from the mean of the total hours they spend outside of class on class work.
