Given:
Machine dispenser
Average = 600 mL soda to every glass
Volumes recorded in one day (random sampling)
600.15
599.92
599.85
599.92
599.81
600.14
600.04
599.98
Average = (sum of the volumes)/(number of readings)
= 4799.81/8
Average = 599.976 mL
Therefore there is sufficient evidence to conclude that the average volume of soda dispenser is different from 600 mL.
Each side of the triangle has a little line through them. This means all 3 sides are equal, so all three inside angles would also be equal.
The three inside angles of a triangle need to equal 180 degrees.
Divide 180 by 3 to find the inside angle for each angle:
180 / 3 =60.
Each inside angle needs to be 60 degrees.
Set the equation with x in it to 60 and solve for x:
2x-4 = 60
Add 4 to each side:
2x = 64
Divide both sides by 2:
x = 64/2
x = 32
