- c) Grams squared.
- d) Grams squared.
-----------------------------
- For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
- The variance has the unit squared, both for the sample and the population.
- For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.
-----------------------------
In this question, the data-set is in grams.
- The standard deviation, both for the sample and the population, in items a and b, will be in grams.
- The variance, both for the sample and the population, in items c and d, will be in grams squared.

Answer: X> -11/10
Explanation:
Answer:
x = 33/5
Step-by-step explanation:
4x+x-15+3-8=13
Combine like terms
5x -20 = 13
Add 20 to each side
5x-20+20 = 13+20
5x =33
Divide by 5
5x/5 = 33/5
x = 33/5
6/8-3/8
3/8
the answer to 3/4-3/8 is 3/8
Slope = Change in y / Change in x
= 8 - 2 / 3 - 1
= 6 / 2
= 3
