5/12 equals to 20/48.

Hello there!

First, you need to replace that empty space by a letter. As usual, we replace that empty space by x or y. I pick X :)

\frac{5}{12} =   \frac{x}{48} 

Now, we do something called cross-multiply 

12*x = 48 * 5 

12x = 240

x =  240/12 

x= 20

The missing number is 20
----------------------

We can check if we got the answer right. Replace the hole by 20
so it will be
5/12 = 20/48

when divided 5 by 12, it equals to 0.41
when we divided 20 by 48, it equals 0.41

So yes, 20 is the missing number.


I hope this helps you. Please let me know if you have more questions.

Best of luck!

What is the total if your tip is 20% and your subtotal is 7.47​
SVETLANKA909090 [29]

Answer:

$8.96

Step-by-step explanation:

To find the total amount, multiply the percentage of the tip (20%) as 0.20 with 7.47

(7.47×0.20=1.494)

Add $1.49 to $7.47

(1.49+7.47=8.96)

And there is your total amount with a 20% tip!

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 434 gram setting. It is
yan [13]

Answer:

No, there is not sufficient evidence to support the claim that the bags are underfilled

Step-by-step explanation:

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 434 gram setting.

This means that the null hypothesis is:

H_{0}: \mu = 434

It is believed that the machine is underfilling the bags.

This means that the alternate hypothesis is:

H_{a}: \mu < 434

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

434 is tested at the null hypothesis:

This means that \mu = 434

A 9 bag sample had a mean of 431 grams with a variance of 144.

This means that X = 431, n = 9, \sigma = \sqrt{144} = 12

Value of the test-statistic:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{431 - 434}{\frac{12}{\sqrt{9}}}

z = -0.75

P-value of the test:

The pvalue of the test is the pvalue of z = -0.75, which is 0.2266

0.2266 > 0.01, which means that there is not sufficient evidence to support the claim that the bags are underfilled.
