To find Tim's overall score, first we must find the sum of his scores from quizzes, notes, and tests.
Hence, we have
quizzes = (5 + 2 + 9) = 16/3
notes = (3 + 9 + 5)/3 = 17/3
tests = (9 + 5 + 9)/3 = 23/3
Now, we must consider the percentage that these tests contribute to his overall score. So we have the following:
quizzes = 0.5(16)/3 = 8/3
notes = 0.2(17)/3 = 3.4/3
tests = 0.3(23)/3 = 6.9/3
We now add these to find the overall score which is 8 /3+ 3.4/3 + 6.9/3 = 18.3/3 = 6.1.
Thus, Tim's overall score is 6.1.
Answer: 6.1
Answer:
20/30 or 2/3
Step-by-step explanation:
you and the 7, 11, and 2. Because they play a sport or an instrument then you put the sum over 30. If you simplify it will be 2/3
Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
Answer:
the first option is the correct answer
