7 1/4 - 2 4/5
Turn the denominator into a common denominator for both fractions:
7 5/20 - 2 16/20
To subtract easier, turn the fractions into an improper fraction:
145/20 - 56/20
Subtract the numerators:
145 - 56 = 89 ---> 89/20
Simplify (to get an answer of):
4 9/20
Add labels:

Answer:
B) Mean
Step-by-step explanation:
Standard Deviation is the measure of the amount of variation or dispersion of a set of values. Standard Deviation is represented by lower case Greek alphabet sigma σ. Standard Deviation is the square root of variance. Variance is the average of the squared differences or variation or dispersion from the Mean. Therefore, to compute standard deviation, the mean of the given data must be known.
Standard Deviation, σ = 
σ = 
∑
where
are the values of the sample observed,
X is the mean value of these observations, and
N is the number of observations in the sample.

Answer:
2 5 /14
Step-by-step explanation:
−10 2/7 ÷ (−4 4/11)
Change to improper fractions
−10 2/7 = - (7* 10+2)/7 =-72/7
-4 4/11 = -( 11*4+4) = -48/11
-72/7 ÷ -48/11
Copy dot flip
-72/7 * -11/48
Canceling an 8 from the top left and the bottom right
-9/7 * -11/6
Canceling a 3 from the top left and the bottom right
-3/7 * -11/2
33/14
Now we change it back to a mixed number
14 goes into 33 2 times 2*14 = 28
33-28 = 5 this goes over the denominator
2 5 /14
