Step-by-step explanation:
Hope this helps : )
The histogram is attached. Every column shows on the bottom the range of age and on the left the number of cars of that particular age.
In order to find the percentage of cars with less than 20 years or more than 40 years, you have to sum up the numbers of cars in the first two columns from left (age 0-9 and 10-19) and the last two (age 40-49 and 50-59).
The number of cars of requested age is: 3 + 2 + 0 + 3 = 8
Now, you need to calculate the total number of cars (sum the cars of every column): 3 + 2 + 8 + 4 + 0 + 3 = 20
Lastly, you need to calculate the ration between the cars of requested age and the total number of cars, and transform it into a percentage:
8 ÷ 20 = 0.40 = 40%
Therefore, your answer is
40%.
Question D:
The terms in the expression are '60a' and '30c'
Question E:
Factors of 60a could be
2 × 30 × a
3 × 20 × a
4 × 15 × a
5 × 12 × a
6 × 10 × a
Question F
Factors of 30c could be
2 × 15 × c
3 × 10 × c
5 × 6 × c
Question G
Coefficient of 60a is '60'
Coefficient of 30c is '30'
Question H
The meaning of the two terms
Term '60a' means multiply the value of 'a' by 60 to find the total cost for 'a' number of adults
Term '30c' means multiply the value of 'c' by 30 to find the total cost for 'c' number of children
