The middle number is 0 and the last is -81Factoring means we want something like(b+_)(b+_)We need two numbers that add together to get and Multiply to get -81which are 9 and -9:<span><span>9+-9 = 0 and </span><span>9*-9 = -81</span></span>
Fill in the blanks in
(b+_)(b+_)
with 9 and -9 to get...<span><span>(<span>b+9</span>)</span><span>(<span>b−9</span>)</span></span>
The answer is : (b+9)(b−9)

I believe the answer is A, the standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the observations, whereas the range considers only the largest and the smallest. Range gives an overall spread of data from the lowest to the largest and thus can be influenced by anomalies, standard deviation on the other hand, takes into account the variable data/spread about the mean and allows for statistical use so inferences can be made.<span />
Answer:
undefined
Step-by-step explanation:
Since we have two points we can use the slope formula
m = (y2-y1)/(x2-x1)
= (-2--6)/(4-4)
= (-2+6) / 0
We cannot divide by 0 so the slope is undefined
Answer:
7
Step-by-step explanation:
The range is the difference between the largest and smallest values in the data set, thus
range = 9 - 2 = 7
Answer:
Step-by-step explanation:
Since it's 3 people splitting 10 oz, we get: 
which equals 3 1/3
