Answer:
18, 21, 36
Step-by-step explanation:
Let L represent the least number. Then the greatest is 2L and the middle number is (L+3). Their sum is ...
L +(2L) +(L+3) = 75
4L = 72 . . . . . . . . . subtract 2, collect terms
L = 18 . . . . . . . . . . . divide by 4
L+3 = 21
2L = 36
The numbers are 18, 21, and 36.
Answer:
The 89th term would be 895.
Step-by-step explanation:
There is a pattern of adding 10 each time. Notice that the 5 at the end doesn't change and that the first number continues (i.e. 2, 3, 4, 5, 6). All you have to do is add an 89 in front of the 5 and that is your answer, 895.
Answer:
<u>The correct answer is that a student have to score 1.41 standard deviations above the mean to be publicly recognized.</u>
Step-by-step explanation:
For answering the question, we don't know the score mean of the National Financial Capability Challenge Exam and neither the population or number of students who take the exam. The only information provided is that the public recognition in this normal distribution is only for students that scores in the top 8%. In other words for students above 92% of the population.
With this information, we can go to a Z Score Table and check that for being on the top 8% (above the 92% of any population), your result must be 1.405 standard deviations above the mean.
<u>Rounding the answer to 2 decimal places, it's 1.41 standard deviations above the mean.</u>
