Answer:
Explanation:
Here, we want to get the value of x and y
From the given image, the angle y and 116 lie on a straight line
The sum of the angles on a straight line is 180 degrees
Thus:
The sum of the internal angles of a polygon can be calculated by the formula:
where n is the number of sides the polygon has
In the case of the given question, n is 4
Substituting the value of n, we have it that:
To get the value of x:
I need an operation, sweetheart. Are you looking for a sum, difference, what?
It looks like the answer to your problem is -9/n
Answer:
Finding the mean from the line plot is a matter of finding the average. My rationale for my answer is written below:
Step-by-step explanation:
1.) Add all numbers together - 0+1+2... = 136
2.) Divide by the amount of numbers given - 136/17 = 8.
3.) 8 is your final answer.
You have the right idea for the first part. There are three ways to add to 4, and those ways are: 1+3 = 4, 2+2 = 4, and 3+1 = 4. This is out of 6*6 = 36 ways to roll two dice. That leads to 3/36. You then reduce the fraction 3/36 to get 1/12. Divide both parts by 3 to reduce.
So the first answer is 1/12
----------------------------------------------------------------------------------------
The first answer is used to help find the second answer. The probability of getting a single "4" is 1/12, so the probability of getting three "4"s in a row is (1/12)^3 = (1/12)*(1/12)*(1/12) = 1/1728
Second answer is 1/1728
