You can represent and odd integer with the expression 2n + 1, where n is any integer. write and solace and equation to find thre
Wittaler [7]

As consecutive odd numbers differ by two (example: 3, 5, 7), the first odd number can be expressed as 2n + 1, the next can be found by adding two to the first to get 2n + 1 + 2 which simplifies to 2n + 3. Finally the expression for the third consecutive odd integer can be found by adding two to the previous, 2n + 3, to get 2n + 5.  Adding these three together and setting them equal to your sum gets the equation

 2n + 1 + 2n + 3 + 2n + 5 = 63

 Combine like terms and solve For n.

Once you have n, you must substitute it back into your three expressions (2n + 1, 2n + 3, 2n + 5) to find the three odd integers.  

 

Hope this helps :)

Charles has collected data to find that the total snowfall per year in Reamstown has a normal distribution. Using the Empirical
Mazyrski [523]

Answer:

0.8413 or 84.13%

Step-by-step explanation:

Given : The mean is 72 inches and the standard deviation is 15 inches

To Find : What is the probability that in a randomly selected year, the snowfall was less than 87 inches

Solution:

Mean = \mu = 72

Standard deviation = \sigma = 15

Formula : z=\frac{x-\mu}{\sigma}

We are supposed to find the probability that in a randomly selected year, the snowfall was less than 87 inches

So, x = 87

Substitute the values in the formula

z=\frac{87-72}{15}

z=1

Now to find P(z<87) refer the z table

P(Z<87)=0.8413 = 84.13%

So, the probability that in a randomly selected year, the snowfall was less than 87 inches if the mean is 72 inches and the standard deviation is 15 inches is 0.8413 or 84.13%

I need some help remembering how to solve the equation 14=8-6r
aleksandrvk [35]
Add 8 to both sides of the equation. Then you would be left with 22=-6r to which you would divide both sides by -6 to get R
