This is NOT a function. The reason why is because we are able to pass a single vertical line through more than one point on the cure. It fails the vertical line test.

For it to be a function, every input x must lead to exactly one output y

You randomly sample 5 people in your​ school, and none of them is a vegetarian. Does this mean that the probability of being a v
kap26 [50]

Answer:

B.

Step-by-step explanation:

The sample size taken for the school is too small.

5 people not being vegetarian does not mean NO OTHER students are vegetarian also. Thus, an assumption based on this probability of 5 people would not be correct unless fully supported. This makes option A wrong.

Answer B is correct because with small numbers, probability varies a lot and may change drastically with the addition of data.

For example: the 6th person we sample says he/she is a vegetarian.

This would change the probability drastically to 1/6 = 0.1667

Because this is a drastic change, and fluctuation is clear, answer B is correct.

C is wrong because probability is not subjective.

Steve recieves a commission of $500 per sale on the first 4 sales he makes a $600 per sale for the next 6 sales he makes during
UkoKoshka [18]
Amount of commission received by Steve for the first 4 sales of the month = $500
Amount of commission received by Steve for the next 6 sales of the month = $600
Amount of commission made by Steve
 for the first 10 sales of the month = (500 + 600) dollars
                                                       = 1100 dollars
Average commission received by Steve per sale during the month = 1100/10 dollars
                                                                                                           = 110 dollars
So the average commission received by Steve for a single sale during the month is $110. I hope the procedure is clear enough for you to understand.

12 students share 3 pizzas equally what fraction of the pizza each student gets
alekssr [168]
To find the solution, simply take 3 and divide it by 12. 3/12 as a fraction would be simplified down to 1/4 or 0.25. Therefore, each student would receive one quarter of a pizza.
