Answer:
x = 80
Step-by-step explanation:
Total = 360
90 + 50 + 90 + 50 = 280
360 -280 = 80
Answer:
<h2>A = 9/4</h2>
Step-by-step explanation:
The formula of an area of a square with side z:
A = z²
We have z = 3/2. Substitute:
A = (3/2)² = (3/2)(3/2) = 9/4
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:
15
Step-by-step explanation:
90 - 30 = 60
60 - 45 = 15
