A rectangle has an area of 216.24 cm2 and a height of 15.9 cm. How long is the base of the rectangle ?

1 answer:

5 0

The formula for the area of a rectangle is A = bh.
Substitute 216.24 for A (area) and 15.9 for h (height).

A = bh
216.24 = b(15.9)
÷ 15.9 ÷ 15.9 Divide 15.9 on both sides.
13.6 = b

So, the base of the rectangle is 13.6 cm.

What effect does increasing the sample size have on a distribution of sample means?

Anika [276]

If the number of samples is increased, this actually leads to a reduction in error of the distribution. This is because of the relationship between variation and sample size which has the formula of:

σx = σ / sqrt (n)

So from the formula we can actually see that the variation and sample size is inversely proportional.

Which means that increasing the sample size results in a reduction of variation.

Answer:

It will have less variation
