The mean is 2.5. also there is mean, median, mode calculators online to help you with these in the future
Answer:
disagree
Step-by-step explanation:
If the triangle is right, then the square of the longest side must equal the sum of the squares on the other 2 sides.
longest side = 12 ⇒ 12² = 144
7² + 7² = 49 + 49 = 98
Since 144 ≠ 98 then triangle is not right

Answer:
y= 5x - 3
Step-by-step explanation:
For the slope, use this formula (y2 - y1) / (x2 - x1)
I used (1,2) and (2,7) from the chart
plug 7 for y2, and 2 for x2
then plug 2 for y1, and 1 for x1
7-2 / 2-1 = 5/1 = 5 <-- this is the slope.
Find the y intercept by plugging in (1,2) into y=5x + b
2 = 5(1) +b
2= 5 + b (subtract 5 on both sides)
-3 = b
So the answer is y= 5x - 3
