For this ones the second value is always negative so A is not correct. Also they have to have an exact square root which 50 doesn't. So the answers are B and C
(a-6)(a+6)
(w-11)(w+11)
Answer:
C. 30
Step-by-step explanation:
-It is a statistical rule of thumb that the size of a sample must be .
-This size is deemed adequate for the Central Limit Theorem to hold.
-At this size or greater, the shape of the resultant distribution is normal.
#It should however be noted, that for a normal distribution the CLT holds even for smaller sample sizes.
The answer would be 859.

49 pieces because 7/8 is equivalent to 49/56. If each piece is 1/56, then there 49 of them.
Answer:
Number 7:
This graph displays the change in wage per years of service. Since the slope is positive, this means the wage has a positive growth.
Number 8:
This graph displays the amount of people evacuating per hour. Since the slope is negative, this means the amount of people evacuating per hour is reducing.
