Predict how many times you would expect to land on a 5 if you roll a standard number cube 36 times.

Answers

Since we're dealing with probability, you have a 1/6 chance to land the dice on 5. and since 6 is a multiple of 36, we can conclude that

1/6 = ? / 36

6 x 6 = 36

6 x 1 = 6

Answer: you should approximately roll a 5 about 6 times

Answer:

6

Step-by-step explanation:

The probability of getting a '5' on one toss is 1/6.  Thus, if you roll the cube 36 times, the predicted number of '5's will be 36(1/6) = 6

1) find the function AND solution of (y = 5x - 4 when x = 5) (y = - 2/5 x + 3/8 when x = 1/3) (y = 3x + 12 when x = 4)
-
2) Show set of data that is a function using at least 5 domain values and 5 range values. It can be shown
in a format of your choice (graph, table, set notation).

Answers

Answer:

Step-by-step explanation:

1)

y = 5x-4 when x=5

y = 5*5-4

y = 25-4

y = 21

y = -2/5x + 3/8 when x = 1/3

y = -2/5 * 1/3 + 3/8

y = -2/15 + 3/8

y = -6/120

y = -1/20

y = 3x + 12 when x = 4

y = 3*4 + 12

y = 12 + 12

y = 24

What is a cylinder?

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given:

Sandra bought coffee in a cup shaped like a cylinder with a radius of 10 centimeters and a height of 20 centimeters.

Sandra fills the cup with coffee, but she leaves 5 centimeters of space at the top to have room for cream.

The volume of coffee in her cylindrical cup,

= (3.14) (100) (15)

= 4710 cubic centimeters.

Therefore, the volume is, 4710 cubic centimeters.
