Answer:

The given equation is

$\sigma^{2}=\frac{(x_{1}- \mu)^{2}+(x_{2}- \mu)^{2}+...+(x_{n}- \mu)^{2} }{N}$

What does the numerator evaluate to?

You can observe that the numerator is formed by the sum between the difference of squares. The difference is between each data and the mean of the data, this difference compares the deviation of each data regarding the mean, that's why the variance measures the degree of deviation of a data set. Additionally, the squares are made to have each difference as a positive number.

What does the denominator evaluate to?

On the other hand, the denominator represents the total number of data. With this denominator, the deviation evaluated in the numerator can be distributed to each data.

At last, the variance equals the degree of deviation of each data in average.

You are making trail mix for your camping trip. You add 2 1/4 cups granola, 5/6 cups of chocolate chips, 1/2 cups of almonds, 1

lesya692 [45]

Answer: The mixed number is 5 5/8 cups of trail mix.

Step-by-step explanation:

Find the least common multiple of 4, 6, 2, 8, and 3, which is 24.
Convert the fractions so they have 24 as their denominator.

2 1/4 ; 9/4 = 54/24
5/6 = 20/24
1/2 = 12/24
1 3/8 ; 11/8 = 33/24
2/3 = 16/24

3. Add the numerators, 54 + 20 + 12 + 33 + 16. 54 +16 = 70. 70 + 20 = 90. 90 + 12 = 102. 102 + 33 = 135.

4. The improper fraction is 135/24. Simplify it by 3 on both numerator and denominator which results in 45/8. 45/8 as a mixed number is 5 5/8 since 8 goes into 45, 5 times and the remainder is 5, which results the denominator to be 8.

Roy uses 1/4 cup of batter for each muffin. Which list shows the amounts of batter he will use depending on the number of muffin

Digiron [165]

I think this is one of the reducing fractions problem:

If we look at option A.{1/4} {1/5} {1/6} {1/7} {1/8}.
Here, the reduced form of all the fractions is not equal to 1/4

If we look at option B. 1/4,2/4,3/4,4/4,5/4.
Here, the reduced form of all the fractions is not equal to 1/4

if we look at option C. 1/4,2/8,3/12,4/16,5/20.
Here, the reduced form of all the fractions is not equal to 1/4

If we look at option D.1/4,2/8,4/16,6/24,8/32.
Here, the reduced form of all the fractions is equal to 1/4
i.e.
1/4 = 1/4
2/8 = 1/4
4/14 = 1/4
6/24 = 1/4
5/20 = 1/4

So, the correct answer is D.
