Answer:
B. two
Step-by-step explanation:
You can expect 76 students in 2018 because from 2014 to 2015 it went up 6, then 8, then 10 so it would increase 12 students from 2017 to 2018
The rate of descent is <em>164.64 meters / minute
</em><em />
<em />To get this answer you just divide the total number of meters descended by the total number of minutes passed.
<em>
</em>So:<em>
</em>922.02 ÷ 5.5 = 164.64
I hope this helped!! Have an amazing day! :D
Distribute: 3x+6+4=5x+7
Simplify: 3x+10=5x+7
Subtract 3x from both sides: 10=2x + 7
Subtract 7 from both sides: 3=2x
Divide by 2: x=3/2
x=3/2
The mean is 35/5=7
The variance is the average of the sum of squared differences of each element from the mean:
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
