A number cube is rolled. What is the probability of rolling 2, 3, or 5?PLEASE HELP!!!!!

Answers

Answer 1

Answer: Since there are six sides of a cube, or a die, the probability of rolling a 2 is 1/6. In the same way, the probability of getting a 3 is 1/6 and getting a 5 is also 1/6. Hence, the probability of rolling 2, 3 or 5 is the sum of all the probabilities each number can be rolled. That is P = 1/6 + 1/6 + 1/6 which is 3/6 or 50%. There is a 50% chance that the number rolled is 2, 3, or 5.

Answer 2

Answer: The probability of rolling any one of these numbers is 1/6, which converted in to percentage is 16.6%. The probability of rolling any two of these numbers is 2/6 which converted in to percentage is 33.3%. The probability of rolling all 3 of these numbers is 3/6, which converted in to a percentage is 50%. Hope it helps:).

6 green = 4 white

There are five 6s in 30

So 5x4= 20

So 30 green 20 white

Simplified form of (3-5i)^2

Answers

Answer:

-16 - 30i

Step-by-step explanation:

(3-5i)^2 = (3-5i) * (3-5i)

Applying the "FOIL" method of expanding this expression through multiplication, we get:

9 - 15i - 15i - 25 (since i^2 = -1)

Simplifying this result, we get -16 - 30i

Is 0.23 a rational number ?

Answers

The given number 0.23 which is the form of decimal is a rational number. The statement is true.

The number in the form of $(p)/(q)$ , where p is numerator and q is denominator and the denominator is not equals to zero, is called as rational number.

The given number 0.23 is a rational number which can be written as $(23)/(100)$ in the fraction form, where 23 is the numerator and 100 is the denominator, which is not equal to zero. So, the number can be considered as a rational number.

Thus, 0.23 is a rational number.

Yes, $\boxed{0.23}$ is a rational number.

Further explanation:

Real numbers includes all the rational numbers (integers and fraction) and all the irrational numbers.

Rational number is any number which can be expressed in the form of $(p)/(q)$ where $p$ and $q$ are integers and $q$ is non-zero and $(p)/(q)$ should be in the simplest form.

And those real numbers which are not expressed in the form of rational number are called irrational numbers.

For example: $\pi$ , $√(2)$ , $√(5)$ .

Here, the number is $0.23$ and which is in the form of decimal.

Express the number $0.23$ in the form of fraction as follows:

$0.23=(23)/(100)$

This implies that $(23)/(100)$ is the fraction form of $0.23$ .

Therefore, the fraction $(23)/(100)$ is in the form of $(p)/(q)$ where, $p$ is $23$ and $q$ is $100$ .

Also, here $q$ which is $100$ is non-zero.

Thus, $0.23$ can be written in the form of rational number.

Hence, $0.23$ is a rational number.

What is the best estimate for 12 2/3 - 9 1/10

Answers

12 2/3 is approximately 12.67, so we can round this up to 13.

9 1/10 is 9.1, so we can round this down to 9.

13 - 9 = 4

So 4 is our estimated answer.

a baseball glove was on sale for 5/6 of the original price. if the original price was $90 what was the sale price

Answers

since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75

Couldn't you go 1/6 x $90. 1/6 being the sale price because 5/6 + 1/6 = 6/6 which is the whole price. 1/6 = 0.166 as a decimal so you would multiply 90 x .16 = 14.40. then $90.00 - 14.40 = 75.60 for the sale price.
