Corey needs 24 boards that ate 47 1/ 2 inches long. How many feet of boards should he buy. Explain

Illusion [34]

If each board is going to be 47 and 1/2 inches long, and there'll be 24 of them, then their total is just their product.

keep in mind that there are 12 inches in 1 foot.

$\bf 24\cdot 47\frac{1}{2}\implies 24\cdot \cfrac{47\cdot 2+1}{2}\implies 24\cdot \cfrac{95}{2}\implies \cfrac{24}{1}\cdot \cfrac{95}{2}\implies \cfrac{2280}{2}
\\\\\\
\stackrel{inches}{1140}\implies 1140~\underline{in}\cdot \cfrac{ft}{12~\underline{in}}\implies \cfrac{1140~ft}{12}\implies 95~ft$

Suppose you have two populations: Population Along dashAll students at a state college (Nequals21,000) and Population Blong d

Answer:

See the explantion below

Step-by-step explanation:

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Assuming the X follows a normal distribution

$X \sim N(\mu, \sigma)$

We know that the margin of error for a confidence interval is given by:

$Me=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

If we see the formula (1) at the same confidence level, for example 95% and with the same sample size the margin of error just depends of the deviation. If the population deviation for population A is higher than the population deviation for B then A will have more margin of error than B.

On the other case if the deviation for population A is lower than the deviation for population B, then we will have less margin of error for population A than population B.

And the other possible case if both population have the same deviation, then both have equal margin of error.
