9 goes into 5, 0 times
9 goes into 52, 5 times

after subtracting 52 from 45 you should have 7 as your difference
now bring down the 2

9 goes into 72 evenly, 8 times.

So your answer should be 58.

To check:

9 * 58:

9 * 8 is 72 carry the 7 over the 5

9 * 5 is 45, plus 7 is 52

Which gives you the answer of 522, the number you started out with.

Complete Question

A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 12 % chose chocolate pie, and the margin of error was given as plus or minus 5 percentage points.What values do $\r p , \ \r q$ , n, E, and p represent? If the confidence level is 90%, what is the value of $\alpha$ ?

Answer:

$\r p$ is the sample proportion $\r p = 0.12$

$n$ is the sample size is $n = 500$

$E$ is the margin of error is $E = 0.05$

$\r q$ represents the proportion of those that did not chose chocolate pie i.e $\r q = 1- \r p$

$\alpha = 10\%$

Step-by-step explanation:

Here

$\r p$ is the sample proportion $\r p = 0.12$

$n$ is the sample size is $n = 500$

$\r q$ represents the proportion of those that did not chose chocolate pie i.e

$\r q = 1- \r p$

$\r q = 1- 0.12$

$\r q = 0.88$

$E$ is the margin of error is $E = 0.05$

Generally $\alpha$ is the level of significance and it value is mathematically evaluated as

$\alpha = ( 100 - C )\%$

Where $C$ is the confidence level which is given in this question as $C = 90 \%$

$\alpha = ( 100 - 90 )\%$

$\alpha = 10\%$

Two integers, a and b, have a product of 24. What is the least possible sum of a and b?

rjkz [21]

The least possible sum is 10.

The pairs of factors for 24 are (1,24), (2,12), (3,8), (4,6) with sums 25, 14, 11, 10. So the numbers are 4 and 6.

Rearrange the equation a = 1/2 b to make b the formula

Evgesh-ka [11]

Answer: b = 2a

Step-by-step explanation:

<u>Original equation</u>

a = (1/2) b

<u>Multiply 2 on both sides</u>

a * 2 = (1/2) b * 2

$\Large\boxed{b=2a}$

Hope this helps!! :)
