Answer:

Option (a) is correct.

The volume of given cone is 72π cubic units.

Step-by-step explanation:

Given : A cone has a diameter of 18 units and height of 8 units.

We have to determine the volume of the given cone.

We know Volume of cone = \frac{1}{3} \pi r^2 h

Where r is radius of cone

h is the height  of cone

Given : diameter = 18units  so, radius is half of diameter = 9 units

height = 8 units

Substitute, we have,

Volume of cone = \frac{1}{3} \pi\cdot (9)^2\cdot 8

Simplify, we have,

Volume of cone = 72\pi

Thus, the volume of given cone is 72π cubic units.

Option (a) is correct.

A shipment of 40 fancy calculators contains 3 defective units. What is the probability if a college bookstore buys 20 calculator
JulsSmile [24]

Answer:

38.46%

Step-by-step explanation:

There are no names or marking that can make the calculator look different, so the order is not important. Then we should use a combination to solve this problem.

There are 40 calculators in one shipment, 37 of them good items and 3 of them are defect items. We need to choose 19 good calculators and 1 defect calculator. The number of ways to do that will be:

\frac{37}{19}* \frac{3}{1}= 37!\frac{37!}{19!(37-19!)} * \frac{3!}{1!(3-1)!}= 53017895700

The number of possible ways to choose 20 calculators out of 40 calculators will be:

\frac{40}{20}= \frac{40!}{20!(40-20!)}=137846528820

The chance will be: 53017895700/ 137846528820 = 0.3846= 38.46%

Write an equation that has a slope of -2 and passes through (-6, 2)
Lelechka [254]

Answer:

y = - 2x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (- 6, 2) into the partial equation

2 = 12 + c ⇒ c = 2 - 12 = - 10

y = - 2x - 10 ← equation of line
