Suppose two 1-6 number cubes are rolled. find the probability of each outcome. P(1 or 5)

Answers

Answer:

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

Step-by-step explanation:

Probability of each outcome with one cube = Number of favorable events for each outcome/Total number of possible events

Replacing with the real values, we have:

Probability of each outcome with one cube = 1/6

Probability of each outcome with two cubes = 1/6 * 1/6 = 1/36

The probability of each outcome rolling two numbered cubes is 1/36 or 2.8% (Rounding to the next tenth)

Andrew is trying to create a number puzzle for his younger sister to solve. He challenges his sister to find the mustery number. when 4 is subtracted from half a number the result is 5. The equation to represent the mystery number is 1/2m -4 =. Andrews sister tries to guess the mustery number. Her first gues is 30. Is she correct? why or why not? What is the correct answer?

Answers

She is not correct b/c if you solve the problem the mystery number is 18.

1/2m-4=5
+4 +4
1/2m=9 divide 9 by 1/3

m=18

You can check by replacing the m with 18 in the original equation and it will equal to 5.

Laura earns $34,350 per year. Laura's income tax rate is 15%. How much income tax does Laura pay each year?

Answers

For this question you would need to make 15% into a decimal. This would make it 0.15. Then multiply 34,350 by 0.15 and you will get the answer.

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

What is inequality?

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

Let x represent the unknown number. The opposite of this number would be represented by -x.

1/3 of this is found by multiplying by 1/3; this gives us

1/3×(-x)

Since it is less than 12, this gives us

1/3×(-x) < 12

To cancel the 1/3, we can multiply both sides by 3:

1/3×(-x)×(3) < 12×(3)

-x < 36

We can cancel the negative by dividing both sides by -1. When we multiply or divide an inequality by a negative number we flip the inequality:

-x/-1 < 36/-1

x > 36

Our number must be greater than 36.
