Step-by-step explanation:
second one is the correct option
Answer:
Yes,because the mean happiness level of the students who did three random act of kindness a week is more than the national mean average.
Step-by-step explanation:
Given that:
the mean happiness level of 6.55 (out of 8)
the standard deviation of the mean happiness level is 0.60
The national mean level of happiness for college students is 5.90
with an unknown standard deviation.
The question is to deduce that would you start doing three random acts of kindness a week.
Yes,because the mean happiness level of the students who did three random act of kindness a week is more than the national mean average.
If the longest side on the similar triangle is 51 and the longest side of the first triangle is 17, then you divide 51 and 17.
51 / 17 = 3
So the similar triangle is 3 times as big.
To find the shortest side of the similar triangle, you multiply 8 and 3.
8 * 3 = 24
The length of the shortest side of the similar triangle is 24.
Hope this helps!
Based on the total number of people who want the steakhouse option, the probability that a student will not want the seafoodbuffet if they want the steakhouse option is 24%
<h3>What is the probability of the students' choice?</h3><h3 />
The probability that a student does not want the seafood buffet given that they want the steakhouse option is:
= Number of people who want steakhouse but not seafood / Total surveyed
Solving gives:
= 9 / (16 + 8 + 9 + 4)
= 9 / 37
= 24%
Full question is:
