Class 2 scored better on average
<h3>How to determine which class scored better on average?</h3>
The averages and the standard deviations are given as:
Class 1
Mean score = 7.8
Standard deviation = 1
Class 2
Mean score = 8.1
Standard deviation = 0.2
As a general rule, the smaller the standard deviation; the better the average
Class 2 has a smaller deviation
Hence, class 2 scored better on average

Answer:
slope- 9 y-intercept- -7
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
9x+18=90
9x=72
x=8
This is the answer for problem 10 above
Problem 11:
62+58= 120
180-120 =60
Therefore angle FEA is 60 degrees
59+ 61=120
180-120= 60
Therefore angle CHF is also 60 degrees
Rays:
EB and HD ; EA and HC are both parallel because they have equivalent degree angles
let's bear in mind that there are, 5280 feet in 1 mile, and that there are 60 minutes in 1 hour and 60 seconds in 1 minute.
bear in mind that we can flip those fractions upside-down, as needed, and the rate remains, we'd flip them to cancel a unit.
