Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
Answer: See explanation
Step-by-step explanation:
Total number of children = 369
Percentage of children on museum trip = 20%
Number of children on museum trip = 20/100 × 369
= 1/5 × 369
= 73.8 = 74 approximately
Number of children in school = 369 - 73.8 = 295.2 = 295 approximately
4 hours = 50$
6 hours = 75$
10 hours = 125$
50 + 75 + 125 = 250?
I'm not sure if I understood your question, because you didn't say like "What is all of these times together?"
Mary, She drank 3/8 and half would be 4/8. So 3/8 is less than 4/8. Please mark brainiest.
