The method for dividing fractions is Keep Flip Change

3 4/5 is equal to 19/5 because you multiply 5*3+4=19. KEEP

(this is just making it into an improper fraction)

The reciprocal of 1/4 is 4 because you FLIP the numerator and denominator.

Now you CHANGE the division sign to multiplication.

So you get 19/5 * 4

19 *4=76

5 *1=5

The answer is 76/5= 15.2

Hope this helps :)

How do you work out a percentile rank of a score of 57
arlik [135]
To do that you'll need the mean and standard deviation of all the scores.  Can you provide this info?

For example:  Supposing that the mean of these scores were 52 and the standard deviation 3.  You'd need to find the "z-score" of 57 in this case.
               57 - 52
It is  z = ------------ , or z = 5/3, or z = 1.67.
                     3

Find the area to the left of z = 1.67.  Multiply that area by 100% to find the percentile rank of the score 57.

What is the value of the digit 5 in the number 225,673.
Tresset [83]

Hello!

To find the value of a digit, we must first look at its place value. When you're given a number, the place value of the number on the furthest right is 1, and for each number you move left, the place value increases by 10 times.

We're given the number 225,673. If we follow this rule, we see the place value of 3 is 1, 7 is 10, 6 is 100, and 5 is 1000.

Since we know that, we now know that there are 5 1,000s, which would make 5,000.

Therefore, your answer is 5,000.

Hope this helps!

A golfer would like to test the hypothesis that the variance of his golf score equals 10.0. a random sample of 28 rounds of golf
Nonamiya [84]
It depends on which statistic test we wish to perform, the formula to find a degree of freedom could be different.

for Normal Distribution test, we do not need to find a degree of freedom

for T-test and Chi-Square test, we do n - 1 to find the degree of freedom, where 'n' is the sample size. 

if we have two different sample size, then the degree of freedom is given by (n₁ + n₂) - 2

We are given only one sample size, n = 28, hence the degree of freedom is 28 - 1 = 27
