Answer:
236
Step-by-step explanation:
The interquartile range is the right edge of the box minus the left edge of the box
The right edge of the box is 301
The left edge of the box is 65
301 -65 =236
The interquartile range is 236
Answer:
x = annual membership fee = $79
y = price per visit = $12
Step-by-step explanation:
Let
x = annual membership fee
y = price per visit
Brian:
x + 8y = 175
Samantha:
x + 13y = 235
x + 8y = 175 (1)
x + 13y = 235 (2)
Subtract (1) from (2) to eliminate x
13y - 8y = 235 - 175
5y = 60
y = 60/5
y = 12
Substitute y = 12 into (1)
x + 8y = 175 (1)
x + 8(12) = 175
x + 96 = 175
x = 175 - 96
x = 79
x = annual membership fee = $79
y = price per visit = $12
Answer:
A =28.26 yd^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We need the radius
r = d/2 = 6/2 = 3
A = pi 3^2
A = (3.14)*9
A =28.26 yd^2
