Answer:-56

Step-by-step explanation:

bc the 7 is negativ and the 8 is positive

Answer:

-56

Step-by-step explanation:

we multiply just like we are multiplying 2 positive numbers

7 times 8 is equal to 56

Now to figure out if it is negative or positive

The rule is if they both have the same signs it is positive but if they are different it is negative

Like a negative times a negative is positive

 A positive times a positive if positive

A negative times a positive is negative which we see in this case so it’s -56

(Sample Spaces LC)

Which event will have a sample space of S = {h, t}?

Flipping a fair, two-sided coin
Rolling a six-sided die
Spinning a spinner with three sections
Choosing a tile from a pair of tiles, one with the letter A and one with the letter B

Answers

Answer: The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive (i.e., they cannot occur simultaneously).

Step-by-step explanation: All we have to do is multiply the events together to get the total number of outcomes. Using our example above, notice that flipping a coin has two possible results, and rolling a die has six possible outcomes. If we multiply them together, we get the total number of outcomes for the sample space: 2 x 6 = 12!

Answer: A: Flipping a Flair, two-sided coin

Yes; The unit rates are the same.


Yes; The line containing these two points passes through the origin.


No; There is no constant of proportionality.

Answers

Answer:

No; There is no constant of proportionality.

Step-by-step explanation:

29.98 divided by 50 is 0.5996 and 15.49 divided by 25 is 0.6196. They are not proportional nor are they equal. There is a difference of 0.02.

Answers

Answer:

Step-by-step explanation:

1: 14.03 x 0.8 = 11.224

14.03 ÷ 0.8 = 17.5375

So, 14.03 x 0.8 < 14.03 ÷ 0.8

2: 6.032 + 1.75 = 7.782

10.142 - 2.36 = 7.782

So, 6.032 + 1.75 = 10.142 - 2.36

3: 578 ÷ 34 = 17

414 ÷ 18 = 23

So, 578 ÷ 34 < 414 ÷ 18

4: 271 ÷ 8 = 33.875

15.05 + 18.825 = 33.875

So, 271 ÷ 8 = 15.05 + 18.825

5: 5.07 x 2.8 = 14.196

19.06 - 4.865 = 14.195

So, 5.07 x 2.8 > 19.06 - 4.865
