Step-by-step explanation:
Step-by-step explanation:
just think it through :
0.4x + 20 < 200
0.4x < 180
x < 180/0.4 = 450
so, x < 450
they must order less than 450 bars.
therefore, the first answer option is correct :
they can order from 0 to 449 bars, but no more.
Answer:
The correct answers are A, D, and E.
Step-by-step explanation:
The expected probability of the spinner landing on an even number is 50%, or 125 times. However, it lands on an even number 135 times, which is equal to 54%. This is more than expected. The actual probability is the probability after an experiment has been conducted, therefore the actual probability of landing on an odd number is 46%. The expected probability is the probability before an experiment is conducted, so it is 50%. It is equally likely for the spinner to land on an even or odd number, because each spin is an independent event.
I hope this helps!
