What is the probability of choosing a vowel out of the word CANYON? Give your answer rounded to the nearest whole percent. PLEAS
2 answers:
The word CANYON has 6 letters
2 of which are vowels (A and O)
To find the probability, you divide the number of the choice you want by the total number of possible choices
What this means it that you're looking for are vowels. There are 2.
But total you actually have 6 letters you could possibly choose.
So you divide 2 by 6
Round the answer to 33%

Step-by-step explanation:
Assuming the following question: Because of staffing decisions, managers of the Gibson-Marimont Hotel are interested in the variability in the number of rooms occupied per day during a particular season of the year. A sample of 20 days of operation shows a sample mean of 290 rooms occupied per day and a sample standard deviation of 30 rooms
Part a
For this case the best point of estimate for the population variance would be:
Part b
The confidence interval for the population variance is given by the following formula:
The degrees of freedom are given by:
Since the Confidence is 0.90 or 90%, the significance and
, the critical values for this case are:
And replacing into the formula for the interval we got:
Part c
Now we just take square root on both sides of the interval and we got:

In triangle ABC: AC=10 , AB=5., Angle C = 30 degrees.
In Triangle DEF: ED= 7.5 , DF=15, Angle F =30 degrees , Angle E = 90 degrees.
Answer:
A, D and E
Step-by-step explanation:
The diagram is drawn and attached below.
- Triangle ABC is similar to Triangle DEF. (Option E)
Writing it backwards:
- Triangle CBA is similar to Triangle FED. (Option A)
Also,
- Triangle BAC is similar to EDF. (Option D).
Therefore, A, D and E are the similarity statements that describe the relationship between the two triangles.
