First you actually find the quotient so divide
3589/80
Which is = 44.86
First digit is 4 when you look at the quotient, starting from the left
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:
Kind of ... any value of x is a solution, but there isn't any unique solution.
Step-by-step explanation:
4(x+1)+x=5(x-1)+9
4x + 4 + x = 5x - 5 + 9
5x + 4 = 5x + 4
Answer: t=6
Step-by-step explanation:
$42+ $6 off = $48
$48 / $8 = 6
