(y2-y1)/(x2-x1)
=(0-1.5)/(-2-0)
=0.5
Answer:
A. mean=14.29
median=16
B. IQR=10
C. option 3
D. 5.91
Step-by-step explanation:
mean=sum of values/number of values=10+20+4+13+21+16+16/7=14.29
median is achieved by arranging data in increasing order and then calculating the middle value
4 10 13 16 16 20 21
The mid value is 16 so the median=16
IQR=interquartile range=3rd quartile-1st quartile=Q3-Q1=20-10=10
As n/4=7/4 is not an integer so
Q1=(n/4+1)value=(7/4+1)=2.75=2nd value=10
Q3=(3n/4+1)value=6.25=6th value=20
Standard deviation=s=sqrt(∑(x-xbar)²/n-1)=sqrt(209.43/6)=5.91
Answer:
Step-by-step explanation:
You have to divide 5 by 2 to find the unit rate.
5/2= 2.5
Hope this helps.
Y= -3x+8
y= 3x+2
both points meet at points ( 1 , 5 )
solve algebraically:
-3x+8=3x+2
+3 +3
_________
8=6x + 2
-2 -2
_________
6/6= 6x/6
x=1
y=3(1)+2
y=3+2
y=5
points: (1,5)
Hello! :D
The simplified answer is: 502 + 14000x
