Answer:
draw a number line from 66 to 81
make your minimum 67
lower quartile should be on 70
the median on 77
upper quartile and maximum on 80
(note that your upper quartile and maximum is both on 80 so there won't be an extension as you normally would see on a box plot)
You can search up "box plot" and go on images to see what i mean

Answer:
1.92 chocolates per in²
Step-by-step explanation:
Given that:
Dimension of conveyor belt :
6.5 inches long and 18 inches wide (6.5in * 18in)
Area of conveyor belt = 6.5 * 18 = 117 in²
Number of chocolate = 225
Number of chocolates per square inch :
225 / 117
= 1.9230769 chocolates
= 1.92 chocolates per in²
Answer:
36 minutes
Step-by-step explanation:
The equation to determine the time together is
1/a + 1/b = 1/c where a and b are the times alone and c is the time together
1/90 + 1/ 60 = 1/c
Multiply each side by 180c to clear the fractions
180c( 1/90 + 1/ 60 = 1/c)
2c + 3c = 180
5c = 180
Divide each side by 5
5c/5 = 180/5
c =36
