For every x value, there should be only one y value. Or, for every input there is only one output.
A - Incorrect - there are two 2's for the x values and each of them has a different y value
B - Correct - all of the x values are different and all of the y values are different
C - Incorrect - there are two 11's for the x values and each of them has a different y value
D - Incorrect - there are two 3's for the x values and each of them has a different y value
Hope this helps! :)
Answer:
See explaination
Step-by-step explanation:
We can define standard deviation in statistics as a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.

Answer:
Shift 8 units up
Step-by-step explanation:
The given function is;
f(x)=x
and
g(x)=x+8
The function f(x) has its y-intercept at y=0.
The function g(x)=x+8 has its y-intercept at y=8
This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
To determine about how many more boys have a shoes size of 6 or less, you need to understand that a box and whisker plot takes a data set and show it in quarters (25% of the data is represented in each section).
For the 2 years olds, if the box in the middle, that means that half of the boys have a shoe size at 6 or under. There were 80 boys chosen for this study, so half of that is 40.
For the 3 year olds, the closest point to 6 is 6.5, and it is located after the line on the left. This means that only 25% of the boys have shoe sizes of 6.5 or under. 25% of the 60 three-year olds they collected data on is 15.
The difference is 40-15= 25.
There are about 25 more two-year olds wearing a size 6 or under.
