To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
Marks UP the price by 30%.
There's two ways:
30% of $22, plus $22.
OR
130% of $22.
To save time, 130% of 22.
130/100 x 22
= 13/10 x 22
=13/5 x 11
=143/5
= 28.6
$28.6
Hope this helps!
Answer:
x=16
Step-by-step explanation:
2(x/8)=2
2x / 16=2
x 16 x 16
2x=32
2x/2= 32/2
x= 16

Answer:
- central: XWR, VWU
- inscribed: VST
Step-by-step explanation:
Point W is the center of the circle. Any angle with W as its vertex is a central angle:
angles XWR and VWU are central angles
Any angle with its vertex on the circle and rays that intersect the circle is an inscribed angle.
angle VST is an inscribed angle
