It is an exponential function because it has a common ratio of 1:3
Answer:
4
Step-by-step explanation:
The mean is the average of a data set. It can be found by adding up all of the values in a data set and then dividing it by the number of values in the data set.
The values in this data set;
The number of values in this data set,
Find the mean;
The stem and leaf diagram is shown below
There are a total of 48 data
Question a:
The frequency in the stem for 9 to 9.9 is 13 data
Question b:
The location of the first quartile is given by
, where 'n' is the number of data
We have n = 48
Location of the first quartile is at
rounded down to 12
The value of the lower quartile is on the
on the diagram which is 8.7
Answer:
y=3/4x+2
Step-by-step explanation:
The slope intercept formula is y=mx+b
b=2 because it is the y intercept
m is the slope
from (0,2) I counted how many points over and up the next point directly on the two lines was , which was point (4,5)
it was 4 to the right and 3 up
slope is rise over run so the slope is 3/4
4, then 13. Since the 4 is positive it doesn’t need to change, and 13 is negative therefore it will be positive
