Three less than a number is 14 more than 2 times that number. What is the number?

loris [4]

Answer:

-20 = - 20

Step-by-step explanation:

Suppose the number is x

three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.

So we can write

x - 3 = 2x +14 - - - - - A

subtract x from both sides

x - x - 3 = 2x - x +14

-3 = x +14

Subtract 14 from both sides

-3 - 14 = x +14 - 14

-17 = x

Or x = - 17

Now can verify our answer by putting the value of x in Eq A

-17 - 3 = 2 x (-17) +14

-20 = - 34 +14

-20 = - 20

I hope this helps. :)

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between and

The planning value for the population standard deviation is 4330.

Given the confidence interval 20000 and 35000.

We have to find the planning value of standard deviation.

Standard deviation is measuring dispersion of data. Uniform probability distribution has two bounds a and b. The standard deviation is given by :

s= $\sqrt{(b-a)^{2}/12 }$ .

Annual starting salaries for college graduates be between 20000 and 35000.

It is uniform in the interval so, a=20000, b=35000.

Now we have to just put the values of a and b in the above formula to get the value of standard deviation.

s= $\sqrt{(35000-20000)^{2} /12}$

= $\sqrt{(15000)^{2} /12}$

= $\sqrt{225000000/12}$

= $\sqrt{18750000}$

=4330

Hence the planning values for the population standard deviation is 4330.
