If you mean between 1/5 and 2/5 then the fraction is 3/10

10 4, 15 6, just multiply it by a number

5/9=x/27 135=9x 15=x

15 + 5 =20 so its 5

7/35 = 5/x You have a proportion here. A proportion is a statement that two ratios are equal. The numbers that form a proportion are called the terms of proportion. There is a special relationship between the terms, called the cross products property. In the proportion that you have, 7 and x are called the extremes of the proportion, and 35 and 5 are called the means. In a proportion, the product of the means equals to the product of the extremes. So, 7/35 = 5/x (7)(x) = (35)(5) 7x = 175 7x/7 = 175/7 x = 25 Thus 7 is to 35 as 5 is to 25.

According to the theory behind a sampling distribution of a proportion, when you take a sample proportion with mean p from a sample of n people, the actual population proportion will follow a normal distribution of mean p with a standard deviation of √(p*(1-p)/n). Using the information given, our sample had a mean, p, of .5 and a sample size, n, of 500. Therefore, the mean of the population is .5 and the standard deviation is √(.5*(1-.5)/500)=.022361. Next, in order to find our probability, we need to calculate the z-scores of our 2 bounds using the formula z=(x-mean)/standard deviation. For .45 this gives (.45-.5)/.022361=-2.236 and for .55 we get (.55-.5)/.022361=2.236. In order to convert this into a probability, we will need to look these values up in a z-table and find the area between them. Doing that we find that the area must be .974653. This tells us that the probability that the population proportion is between 0.45 and 0.55 is 97.4653%.

5/9=x/27 135=9x 15=x

"Is to" usually indicates a ratio or a proportion. 5 is to 10 as 9 is to 18.

10 is the number halfway between -5 and 15.It is: 5

-5

15 + 5 =20 so its 5

If you mean 2/5 of 15 then it is 6
