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

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

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that expression
−0.05 x 24 1 /2
We have;

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
