$48

Divide 48 by 12 to see how many ratios you will need
So there will be 4 since 48/12=4
Then, multiply 4x7 (for each ratio given to the charity
4x7=28

So, he will be donating $28 for every $48

D. 28

this is because 48 divided by 12 is 4, 4 times 7 is 28.

How to factor (16+2x)(12+2x)=396
morpeh [17]
First, you have to combine all the like terms such as both the 2x’s and 16 and 12 which will give us 28+4x=396. Then you subtract 396 from 28 which is 368. You want the variable x to be alone so you divide 368 by 4 which gives you 92.

An IQ test is designed so that the mean is 100 and the standard deviation is 1414 for the population of normal adults. Find the
Amanda [17]

Answer:

37

Step-by-step explanation:

The first thing is to calculate critical z factor

the alpha and the critical z score for a confidence level of 90% is calculated as follows:

two sided alpha = (100% - 90%) / 200 = 0.05

critical z factor for two sided alpha of .05 is calculated as follows:

critical z factor = z factor for (1 - .05) = z factor for (.95) which through the attached graph becomes:

critical z factor = 2.58

Now we have the following formula:

ME = z * (sd / sqrt (N) ^ (1/2))

where ME is the margin of error and is equal to 6, sd is the standard deviation which is 14 and the value of z is 2.58

N the sample size and we want to know it, replacing:

6 = 2.58 * (14 / (N) ^ (1/2))

solving for N we have:

N = (2.58 * 14/6) ^ 2

N = 36.24

Which means that the sample size was 37.
