Answer:
5/11
Step-by-step explanation:
Probability is the chance that something will happen. Basically, it answers the question of how many times an event will occur in a given number of opportunities.
In this example, the word "GEOMETRICAL" has 11 letters and 5 of them are vowels. They are: E, O, E, I, A. The probability of picking a vowel is 5/11. We could say that there are 5 out of 11 chances of a vowel to occur whenever a piece of paper is taken out of the bag.
Answer: a. confidence level.
Step-by-step explanation:
Given : A newspaper provided a "snapshot" illustrating poll results from 1910 professionals who interview job applicants.
i.e. Sample size : n= 1910
The illustration showed that 26% of them said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company.
The point estimate of the proportion of job applicants said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company = p=0.26
[Note : The point estimate of the population proportion is basically the sample proportion.]
The margin of error was given as plus or minus 3 ±3 percentage points.
But confidence level is necessary to describe the margin of error .
A confidence interval tells how sure you are about the margin of error .
Thus , the important feature of the poll was omitted = confidence level
Unit price is total price/ quantity purchased.
21.16 / 4 = 5.29
Unit price = $5.29 per pair
Answer:
Inverse of -5-9x/x-6
Step-by-step explanation:
Steps:
1: Interchange the variables x and y.
x=6y-5/y+9
2: Solve x = 6y-5/y+9 for y
3: Multiply both sides by y+9
4: Simplify and Expand
5: Subtract 9x from both sides.
6: Simplify and Subtract y from both sides then Simplify again
7: Divide both sides by x-6
Answer: Inverse of -5-9x/x-6
