On your graph for the bottom numbers write 1,2,3,4,5 and on the left side write 4,8,12
To be able to graph this you need to start on -2 on the y-axis then move up 5 then 1 to the right
The dot should be on (1,3)
Factorize the numerator as a difference of squares:
Then if 
, the 
factors will cancel:
so the answer is B.
Answer:
Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.
Explanation:
A line intersecting a circle in two places is referred to as a secant. The portion of the secant contained within the circle is called a chord.
This means that both chords and secants intersect the perimeter of a circle twice, chords are entirely inside the circle, and secants extend through a circle to the outside.
Thank you for posting your question here. I think the question is "
<span>What is the estimated mean for the population? Explain your answer and show your work."
Below is the solution. I hope it helps.
</span>µ= (1*248 +2*567 +3*1402 +4*728 +5*419 +6*456 +7*203)/(1 +2 +3 +4 +5 +6 +7)
<span>=14752/28≈ 526.9</span>
