Answer:
2A=A+A
Step-by-step explanation:
2A=A*A, not A+A
If you use a large enough statistical sample size, you can apply the Central Limit Theorem (CLT) to a sample proportion for categorical data to find its sampling distribution. The population proportion, p, is the proportion of individuals in the population who have a certain characteristic of interest (for example, the proportion of all Americans who are registered voters, or the proportion of all teenagers who own cellphones). The sample proportion, denoted
1.4 / 7
multiply by 10 in both up and down
(1.4*10) / (7*10)
14 / 70
divide by 7
(14/7) / (70/7)
2 / 10
divide by 2
(2/2) / (10/2)
1 / 5
Length of parallel sides=8 cm, 9 cm
Distance between parallel sides=6 cm
Area =
2
1
(distance between parallel sides)× (sum of parallel sides)
=
2

×6×(8+9)
=3×17=51
