To find the cost for 1 marker u have to divide 20 by 6. 20/6 is around $0.3. So 30c for one marker
Answer: The professor was not accurate with his hypothesis.
Null hypothesis: P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternate hypothesis: At least one proportion of the student will differ from the others.
Step-by-step explanation: To check if the professors hypothesis were inaccurate.
What percentage of student bought a hard copy of the book.
(25 ÷ 200) × 100 = 12.5%
What percentage of the student printed it from the web.
(85 ÷ 200) × 100 = 42.5%
What percentage of the students read it online.
(90 ÷ 200) × 100 = 45%
This means that the professor was not accurate with his hypothesis. Because the proportion of student in his hypothesis was not the same in the actual.
Therefore; the null hypothesis are
P1 = 12.5%, P2 = 42.5%, P3 = 45%
The alternative hypothesis will state that at least one of the proportion will be different from the others.
Well d = distance. r = Rate. t = Time. Distance = Rate x Time.
To get r by itself you will divide rt by t. Now you have to do that to the other side. so d/t = r. So B :)
The ratio that represents Kyle's batting average at the end of the season is h:10
<h3>Mean or Average</h3>
Mean is defined as the sum of data to the total number of samples.
Given the following
- Total number of hits = h
- Number of bats in a season - 10
Using the formula:
Ratio of the mean = Total number of hits/Number of bats
Ratio of the mean = h/10
Hence the ratio that represents Kyle's batting average at the end of the season is h:10
