Here you go, hope it isn't messy
Answer:
{6,8}
Step-by-step explanation:
{5,6,7,8} intersection {6,8,9}
={6,8}
To determine the answer to this item, we first calculate the z-scores of the given data point through the equation,
z-score = (data point - mean) / standard deviation
For 5:
z-score = (5 - 7) / 1.7 = -1.176
This translates to a percentile of 11.97.
For 10:
z-score = (10 - 7) / 1.7 = 1.76
This translates to a percentile of 96.08.
The difference between the percentiles is 84.11. Thus, 84% of the students sleep between 5 to 10 hours.
Hi There!
Since 3 teachers share 2 packs of paper equally, you have to divide 3/2, once you divide you should get the answer of 1.5, To check you're answer do 1.5*2 which equals to three. So, each teacher gets 1.5 packs of paper.
Hope This Helps :)
3.61 is the answer because there is only two numbers after the decimal
