Answer:
B 70
Step-by-step explanation:
7 |H| + 4 G
H = -6 and G = 7
| H| = 6
7*6 + 4*7
42+28
70
Answer is B.
We see the center lines are 80 and 85 as stated.
A is wrong because the range of class 2 is less.
C is wrong; class 2 has a minimum of 50
D is wrong; class 2 has a smaller interquartile range, which is the width of the boxes.
Sounds like "exponential decay" is the answer your teacher is looking for
Expressions of the form y = a*b^x are considered decay equations or exponential decay equations if 0 < b < 1. So b can be between 0 and 1, but not equal to either endpoint.
Example: y = 3*0.5^x means we start off with 3 as the initial value, and then cut it in half repeatedly as x increases by 1 (eg: x = 0, x = 1, etc). This graph goes downhill as you read it from left to right.
