I not that good with math but I would say C.
Roughly 68% of the distribution is between z = -1 and z = +1, ie within 1 standard deviation of the mean. This is from the 68-95-99.7 rule or better known as the Empirical Rule.
The final answer is choice D) 68.2%
1. Statistical because there is more than one acceptable answer. There could have been any number.
3. Statistical because one middle school may be ( no offense ) average but spend little time on the internet. Another may spend hours.
I hope this helps. For 3 I may be wrong but…
8/52 or 2/13
Because there is 1 queen and 1 jack in each of the 4 suites. so 2x4=8. Out of 52 cards, then simplify.
Answer:
- f(5), t=5 Minutes.
- f(60), t=60 Minutes
Step-by-step explanation:
f(t) is the temperature of the yam t minutes after it is placed in the oven.
- In f(5), t=5 Minutes, therefore f(5) is the temperature of the yam 5 minutes after it is placed in the oven. At f(5), the yam is still in the oven since it is not yet up to 45 Minutes.
- In f(60), t=60 Minutes, therefore f(60) is the temperature of the yam 60 minutes after it is placed in the oven. Since the yam is taken out after 45 minutes, at f(60), the yam is no longer in the oven.
