Answer:
60000
Step-by-step explanation:
The mean is the average
Add all the salaries together
(30000+30000+40000+40000+40000+50000+190000)
420000
Then divide by the number of number
420000/7
60000
Answer:
the answer would be 3. 1 to 2
Step-by-step explanation:
Because for every one answer the team A gets, team B gets 2 so it is a 1 to 2 ratio
The answer is 22,5
To understand percents and how to calculate them it is most important that you remember that one whole is divided into one hundred little peaces. In this case, the whole is 75. So, the easiest way to find a certain percentage of a whole, is to divide it by one hundred and then multiply it with the percent that you want to find. So, to solve your question you have to divide 75 by 100, which gives you that one percent of 75 is 7.5, and then to find what 30 percent of 75 is, you multiply that one percent by 30, or 7.5 x 30, which gives you 22.5 - the wanted solution.
There are other ways of calculating percentage, but this is by far the easiest one for beginners to understand.
Hope it helps :)
Answer:
21.6 hours
Step-by-step explanation:
Hypothesis testing allows to identify a event test. The correct order of the steps of a hypothesis test is given following
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
These steps are performed in the given sequence to test a hypothesis.
The principal tests the hypothesis with a mean of 21.6 hours for the determination of average amount of time spent watching television.
