Answer:
The Orange circle is: 78.5 cm
And The Blue circle is 314.2 cm
Step-by-step explanation:
By taking the formula r^2(pi), and filling it in with the radius for the orange circle you will get 78.5. For the blue circle the radius would be the orange's radius combined with the rim given. Using the same formula you will get 314.2.
to get the mixed number simply just divide the numerator by the denominator.
28/4 = 7
and 7 as a mixed number it would be; 6 4/4 (4/4 equals to 1 and 6+1 =7)
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.

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
