Which graph represents the function f(x)=−3x−2?
1 answer:
Answer:
Top left
Step-by-step explanation:
We can plug in the y intercept to find which graph has the correct one.
x = 0 is y intercept
Thus
At this point we known the y intercept is -3 so both graph in the left is considerable.
Notice that the base is the negative, thus the graph would goes down. Therefore the top left would be correct.

<u>Solution</u><u>:</u>
- When, you rotate a picture by 180°, we rotate it by half of a full circle.
- The first picture is the original picture.
- The second picture is the image when it is rotated by 90°.
- The third picture is the images when, it is rotated once more by 90°. This image is the rotation of the image around P by 180°.
- So, the answer will be option A.

Answer: The mean number of checks written per day
Standard deviation
Variance
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-
Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e.
Standard deviation :
