Answer:a) mean=167.1
b)median=168.5
c)mode= 180
Step-by-step explanation:
Mean= total sum of values in the data set/ number of values
=2339/14=167.1
Median = midpoint = 165+172/2= 337/2= 168.5
Mode= number with the highest number of frequency, for this data set, 180 occurred most because it occurred three times
Answer:

Answer:
xy(y - x)(y + x)
Step-by-step explanation:
take out a common factor xy from both terms
= xy(y² - x²)
y² - x² is a difference of squares and factors in general as (y - x)(y + x)
Hence
xy³ - x³y = xy(x - y)(x + y)
Answer:
all I know is how to get y but y=122
Step-by-step explanation:
y=3(40)+2
y=120+2
y=122
sorry but I dont know what to do for x
