Step-by-step explanation:
Discriminant is the value b^2 - 4*a*c
(-3)^2 - 4*2*1
9 - 8 = 1
Answer: 91.4%
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
Considering cylinder A,
Height = 8ft
Diameter = 8 ft
Radius = diameter/2 = 8/2 = 4ft
Therefore,
Volume = 3.14 × 4² × 8 = 401.92ft³
Considering cylinder B,
Height = 13ft
Diameter = 6 ft
Radius = diameter/2 = 6/2 = 3ft
Therefore,
Volume = 3.14 × 3² × 13 = 367.38ft³
The volume of Container A that would be left empty after container B is pumped into it is
367.38ft³
the percent of Container A that is empty after the pumping is complete is
367.38/401.92 × 100 = 91.4%
Answer:
The sample should be a random sample from the entire set of students and should include enough students to be reliable. Small samples have more variation, which leads to less reliable inferences.
