How do you use the fundamental counting principle?

1 answer:

7 0

In the fundamental counting principle, you are multiplying to get the total number of possibilities as a result. For example, if you have 5 different types of bread, 8 types of cheese, and 6 types of meat, you have 240 choices (8 x 6 x 5).

The volume of cone A is equal to the volume of cylinder B. In addition, their radii are

tekilochka [14]

Answer:

3:1

Step-by-step explanation:

A cone has the same volume formula as a cylinder, except it is 1/3 as much. So to have the same volume, a cone would need to be 3 times as tall.

What is the length of the portion BC of the cloth?

pantera1 [17]

Since this is a right triangle, a triangle with a 90 degree-angle, we can use the trigonometric functions. An example would be the sine function. With respect to the angle, it has the opposite side (o), the adjacent side (a), and the longest side called hypotenuse (h). For the sine function, it would be sine theta = opposite/hypotenuse. Using this relationship,

sin 38 = BC/5
BC = 5*sin38
BC = 3.08 units

Solve and graph this system of equations x+2y=5 and 3x=15-6y

Bogdan [553]

Answer:

(x,y)=(5-2y,y), y belongs to all real numbers

Step-by-step explanation:

x=5-2y

3x=15-6y

3(5-2y)=15-6y

15-6y=15-6y

y∈All Real Numbers

(x,y)=(5-2y,y), y∈All Real Numbers

Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event

Paladinen [302]

Answer:

Step-by-step explanation:

The sample space is shown in the attached photo.

Probability = number of favourable outcomes/total number of outcomes.

Looking at the diagram, the total possible outcomes is 36.

A) from the diagram, the total number of events in which the sum of the numbers is odd is 18. Therefore, the probability that the sum of the numbers is odd is

18/36 = 1/2

B) the total number of events in which the sum of the numbers is 10 or more is 6. Therefore, the probability that the sum of the numbers is 10 or more is

6/36 = 1/6

C) the total number of events in which 3 appears on each of the two dice is 1. Therefore, the probability that 3 appears on each of the two dice is

1/36
