You can write 1/4 as a decimal, equivalent fraction, and a percent.

To change 1/4 into a decimal, divide the numerator by the denominator. You will get 0.25. To make 1/4 into a percent, multiply the decimal by 100 or just move the decimal two places to the right. The percent is 25%. To make 1/4 into another equivalent fraction, multiply the numerator and denominator by the same number. For example, you can multiply the numerator by 2 and the denominator by 2. So, another equivalent fraction for 1/4 is 2/8.

Hope it helps :)

You could do 0.25 (decimal way), 25% (fraction way), or even use equivalent fractions like 2/8 or 25/100.

Statistics please help I'm not good worth 50 points

(a) I can't help you with using your calculator for this part, but if you have some familiarity with your device you can check your answer with mine.

The mean is simply the sum of all the house costs divided by the number of houses:

(75k + 75k + 150k + 155k + 165k + 203k + 750k + 755k)/8 = 291k

So the population mean is $291,000.

The population standard deviation is the square root of the population variance. To get the variance, you take the sum of all the squared differences between the cost and the mean cost, then divide that sum by the number of houses. That is,

[(75k - 291k)² + (75k - 291k)² + … + (755k - 291k)²]/8 = 581,286k

Note that the variances is measured in square dollars. Then the standard deviation is

√(581,286k) ≈ $762,421.1

(b) The median is just the price in the middle. There were 8 houses sold, so there are 2 "middle" prices. The median is the average of these:

(155k + 165k)/2 = 160k = $160,000

(c) Yes, the mode is the data that shows up most frequently. This happens at the lower end, with $75,000 appearing twice.

2) In August, Emily's Clothing Store sold 460 shirts with the ratio of short sleeve to long

aivan3 [116]

Answer:

138

Step-by-step explanation:

We know that there are at least 3 short sleeved shirts and there are at least 7 long sleeved shirts. And we know it's in that ratio. So the best way to start this is to divide 460 by 7+3 to get the single unit amount of both shirts.

46 is the single unit amount. So 46 * 3 will get us our short sleeved shirts:

46 * 3 = 138

To check our answer, we'll take 460-138 and divide that by 7 to see if we get 46:

322/7 = 46

So the answer is correct!
