If a die is rolled 36 times, how many times is the number 4 expected to come up?

Mathematics

Snezhnost [94]3 years ago
4 0

Answer: 4/36 or 1/9

Step-by-step explanation: The answer will be 1/9 because when a dice is rolled 6 times, every number has a 1/6 chance of being the number. So if the die is rolled 36 times, the number will show up 1/9 of the time.

a set of five numbers has a mode of 24 a median of 21 a mean of 20 . work out what the numbers could be
SSSSS [86.1K]

Answer:

Step-by-step explanation:

The mode is 24 so we know that at least 2 of the 5 numbers are 24.

The mean is 20 so we know that the 5 numbers add up to 100.

The median is 21 so the third number is 21.

100-(24+24+21)= 31

Now, I am pretty certain that the last 2 numbers can be anything as long as they add up to 31 AND they are not also 21 because 24 then would no longer be the mode.

E.g. 24, 24, 21, 11 & 20

3/2=4/3x+2/3 What does X equal?
Anna71 [15]

Answer:

x = 30/48 or x = 0.625

Step-by-step explanation:

3/2 = 4/3x + 2/3

Convert to common denominator

9/6 = 8/6x + 4/6

subtract 4/6 from both sides

9/6 - 4/6 = 8/6x + 4/6 - 4/6

5/6 = 8/6x

Divide by 8/6

5/6 x 6/8 = x

30/48 = x

x = 30/48

If my answer is incorrect, pls correct me!
