Answer:

8,800,000cars

Step-by-step explanation:

Given the initial amount of cars = 80,000,000

If there is 10 % increase in the first year;

Increment = 10% of 80,000,000

Increment = 0.1 * 80,000,000

Increment = 8,000,000

Amount of car in year 2 = 80million + 8million = 88million

Year3;

Amount of car in year 3 = 88,000,000+(10%of88million)

Amount of car in year 3 = 88,000,000+8,800,000

Amount of car in year 3 =96,800,000

Differences in the number of cars = 96,800,000 - 88,000,000

Differences in the number of cars = 8,800,000cars

Hence there are 8,800,000cars in years 3 than year 2

Help with this math equation please help

Answer:

i. Girls : 10 merits

ii. Boys : 11.4 merits

iii. The boys did better on average because the number of their mean merits received is higher than that girls.

Step-by-step explanation:

Mean = $\frac{sum of merits}{number of merits}$

Sum of merits received by boys = 5 + 10 + 19 + 22 + 13 + 10 + 1

= 80

number of merits = 7

Mean number of merits received by boys = $\frac{80}{7}$

= 11.4286

The mean number of merits received by boys is 11.4

Sum of merits received by girls = 6 + 11 + 15 + 16 + 12 + 10 + 0

= 70

number of merits = 7

Mean number of merits received by girls = $\frac{70}{7}$

= 10.0

The mean number of merits received by girls is 10.0

Therefore,

i. Girls : 10 merits

ii. Boys : 11.4 merits

iii. The boys did better on average because their mean merits is higher than that girls.
