C as there are only 3 terms tip- (count how many symbols). And the highest power it goes to is 2 so it’s 5y squared. Hope this helps :)
Unit rate is in the quantity of one.
2/1 is a unit rate
6/3 is a rate
4/1 is a unit rate
Answer:
48
Step-by-step explanation:
Given that:
The interval for score = 60 - 42 = 18
If we divide it by the 3 standard deviations; the interval result into
= 18/3
= 6
So, the standard deviation is 6, and the mean = 42 + 6
= 48
Normally, one would have a certain pattern and they would make an equation to make the prediction for what values would come next in a sequence ( or at some x value ), but if one had an equation such as y=3x+4 ( I am using examples because this was a very general question ) they could see that when x is 0 y=4 and that the y value increases three units for every change in x value. since y=4 when x=0, 4 may be called the initial value as well as the y-intercept ( in fact this is generally true for all mathematical models ). This is where the pattern starts.
