The equation of the line parallel to 6x+2y=49 is y=-3x+21. This also includes the point (4,9)
Answer:
3. t-test for the difference between means for two related samples.
Step-by-step explanation:
It is given that a professor of UCI wishes to study what really the students remember from their elementary school days and other such stuffs that were very popular at that time.
therefore the professor put forward two test. In one of the test, he put some question from the elementary school and in other he put one question about a pop culture from that time. He used the same sample for both the tests.
So, since the professor involved the same set of students in his experiment for both the tests, so both the samples are related samples.
Therefore, the test uses is a t - test that is used for the difference between the related samples.
x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
Letter C
Since we had the answers we could have just tried the answers but you will not always have multiple choice so this is the method for solving.
No
There is not a common factor

Step-by-step explanation:
Formula for Poisson distribution: where k is a number of guests coming in at a particular hour period.
(1) We can substitute k = 7 and into the formula:
(2)To calculate the probability of maximum 2 customers, we can add up the probability of 0, 1, and 2 customers coming in at a random hours
(3) The probability of having at least 3 customers arriving at a random hour would be the probability of having more than 2 customers, which is the invert of probability of having no more than 2 customers. Therefore:
