Answer:
The answer is C
Step-by-step explanation:
2x + 4y
2 x 3 = 6
4 x 6 = 24
24 + 6 = 30
Answer:
You calculate the distance between the angle and the arch and you can solve your answer.
Step-by-step explanation:
For example... An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π radians = 180° π r a d I a n s = 180 ° .

First find the inverse function:
y = -x^2 + 2
y - 2 = -x^2
2 - y = x^2
x = (2 - y)^0.5
Therefore inverse: y = (2 - x)^0.5 [x < 2]
Then simply sub in four random values for x to give your answer (hint, for your x values, use 1, - 2, - 7 and - 14. These should yield nice integer values for y)
Answer:
(you)
(friend)
So as we can see we got the same z score for both cases so then we can conclude that:
You and your friend are equally ranked.
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:
Where and
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we have a z score greater we have a bettr result since the value would be on a higher percentile of the distribution. So if we find the two z scores for the scores given we got:
For the other instructor the distribution changes and would be:
Where and
And the z score for the friend would be:
So as we can see we got the same z score for both cases so then we can conclude that:
You and your friend are equally ranked.
