Answer:
Each side is 10 inches because the perimeter is 80 inches, you will have to divide 80 by 8 because octagon is a shape with 8 sides. So 80 divided by 8 is 10..... So the answeer is 10 inches.
Step-by-step explanation:
80÷8=10

The value of x in terms of b is x =
. Therefore the value of x when b = 3 is x =
= -1.
We can find both answers by rearranging the equation to get "x =", and then substituting in 3 for b:
-2(bx - 5) = 16
-2bx + 10 = 16
- 10
-2bx = 6
÷ -2
bx = -3
÷ b
x = -3/b, which is the answer to the first part.
To get the second answer, we just substitute b = 3 into this equation and we get:
x = -3/b = -3/3 = -1
I hope this helps!
3 Feet = 1 Yard
If you divide the 412/3 you will get the answer
412/3=137.33333333
Answer:
412 Feet = 137.3 yards
Answer:
![X \sim N(\mu, \sigma)](https://tex.z-dn.net/?f=X%20%5Csim%20N%28%5Cmu%2C%20%5Csigma%29)
And from this case we can see that the deviation is given by:
![\sigma = 3](https://tex.z-dn.net/?f=%5Csigma%20%3D%203)
Step-by-step explanation:
For this case we have the following notation given:
![X \sim N (5,3)](https://tex.z-dn.net/?f=%20X%20%5Csim%20N%20%285%2C3%29)
And from this we know that the distribution for the random variable is normal and we know that in general the normal distribution is given by:
![X \sim N(\mu, \sigma)](https://tex.z-dn.net/?f=X%20%5Csim%20N%28%5Cmu%2C%20%5Csigma%29)
And from this case we can see that the deviation is given by:
![\sigma = 3](https://tex.z-dn.net/?f=%5Csigma%20%3D%203)

so their product is 112, so tis just a matter of doing some quick prime factoring and combining the factors about.
