Answer:
Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.
Step-by-step explanation:
The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...
21/5 = 4.2
The four means are ...
-7 +4.2 = -2.8
-2.8 +4.2 = 1.4
1.4 +4.2 = 5.6
5.6 +4.2 = 9.8
Answer: y=8.5x + 25.5
Step-by-step explanation:
y=mx+b
b= beginning number so thats
25.5 you start there
m= its slope so its 8.5
Answer:
see below
Step-by-step explanation:
360 - 56 - 106 = 198 degrees
198 / 3 = 66 degrees per unit
angle f = 132 degrees
angle g = 66 degrees
Not sure but I think it’s B
