1: 9x+3
2: 3m^2+9m-7
3: 3x^2+3y^2+y+4
Those are all of the answers in order! I hope this helps.
Answer:
There is no mode in the set
B. Because the mean is less than the median comma this distribution's shape is left dash skewed.
Step-by-step explanation:
Data set = {25, 18, -9, 14,32}
We find sum = 80 hence mean = 80/5 = 16
No mode since nothing is more repeated
Median is the middle entry after arranging in ascending order = 18
a) x bar=16
b) median = 18
c) mode is nil
Here median - mean >1
so negatively skewed
There is no mode in the set
B. Because the mean is less than the median comma this distribution's shape is left dash skewed.
Check the picture below.
bear in mind that, arcs get their angle measurement, from the central angle they're in.
Answer:
19.9
Step-by-step explanation:
we can write the following equation
18000(1.02)^n
where n is the number of years
so we have
26700=18000(1.02)^n
solve for n
1.483=1.02^n
use logs to solve for n
n=19.9
