Answer:
the slope is 1/2
Step-by-step explanation:
No solutions.
To solve, set the two equations equal to each other.
6x +9 = 6x +2
cross out the 6x
9 = 2
there are no instances where 9 = 2, so there are no solutions.
Answer: B) 160
<u>Step-by-step explanation:</u>
Since the Standard deviation of 21 bins is 3 bins, then the first 7 bins falls in the first 2.5% edge of the bell curve.
