So, the area of a parallelogram is the base times the height or
a being area
b being base
h being height
the height is 8 cm and the base is 15 cm
(remember: the heght should be perpendicular to the base)
so we plug in 8 for h and 15 for b to get
and 15 × 8 = (10 × 8) + (5 × 8) = 80 + 40 =120
So the answer is 120
Using the Central Limit Theorem, it is found that these conditions are required to avoid the high variability associated with small samples.
<h3>What does the Central Limit Theorem states?</h3>It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportion is approximately normal with mean and standard deviation
, as long as
and
.
From the equation of the standard error, we could see that if one of the conditions is not respected, the standard error would be very high, indicating a low accuracy of the estimate, hence it is found that these conditions are required to avoid the high variability associated with small samples.
