directions - just explain how to do each of the things listed above. take your time. I'll mark brainliest to the first person who answers. Thanks!

Answers

Answer:

1: When adding integers that have the same sign make sure to keep the sign the same and only add the absolute of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

2: When subtracting integers keep the first number the change from subtraction to addition after that get the opposite sign of the second number (known as the subtrahend) Finally get the regular addition of integers.

3: When multiplying integers you have to first get the absolute of each number then multiply the absolutes then determine the sign for the final answer.

4: When dividing integers find the absolutes then divide the numbers and then simply find the sign (Usually positive)

Step-by-step explanation:

Hope I helped I'm learning integers also!

Step-by-step explanation:

Answer:

The product of a non-zero rational number and an irrational number is irrational.

Step-by-step explanation:

For answer 1, if we take 2(a rational number) and 4(another rational number) and add or sum them together, we get 6. (2+4=6) This is clearly also rational as 6 is rational.

For answer choice 2, it follows the same logic. 2*4=8: 2 and 4 are rational and so is 8.

For answer choice 3, we see that any rational number that is not zero multiplied by an irrational number is irrational. A good example of this would be 2 * π = 2π. 2 is rational and not 0 and pi is irrational. 2π is irrational so answer choice 3 seems to be the answer. Also the reason why it cannot be 0 is because pi*0 = 0 so anything multiplied by 0 will equal 0. 0 is rational so if the answer did not say any rational number but 0, it would have been incorrect.

For answer choice 4 it says that the sum of a rational number and irrational number is rational. This is like saying if one part of a statement is true but the other parts are false that the statement is true. So, if we add 2 to pi, would that be rational or irrational? It would be irrational because we still have that neverending sequence of numbers that are in pi, but plus 2 so 3.14... + 2 = 5.13159....

For the wheel picture on the right assume that a person spins the pointer and is awarded the amount indicated by the pointer. If it costs $5 to play the game determine (a) the expectation of a person who plays the game and (b) the fair price to play the game.

a. what is the expectation? $ ___​

Answers

Answer:

(a)

(b)

Step-by-step explanation:

First pic is a second is b

The expectation to play the game is $2.5 and the fair price to play is $7.5.

What is the expectation?

The expectation is defined as the weighted average value of the random variable which is the product of the value of the random variable and its possibility.

Expectation= ∑P(win)*amount of win or loss of random variable

=∑x*P(x)

Here given that there are only two possible outcomes $5 and $10. And the possibility of every outcome is the same which is 0.5 as they occupy the same area.

As we know

Expectation= ∑P(win)*amount of win or loss of random variable

= 0.5(5-5) +0.5(10-5)

=0.5*0 + 0.5*5

=0+2.5

=$2.5

As fair price= expectation + cost of play

⇒fair price= $2.5 + $5

⇒fair price= $7.5

Therefore the expectation to play the game is $2.5 and the fair price to play is $7.5.
