The values that exist two standard deviations above and below the mean are 681 and 265.

<h3>How to determine the values?</h3>

The given parameters exist:

Mean = 473

Standard deviation =104

The values above and below the mean exist calculated utilizing:

$x=\bar{x} \pm n \sigma$

In this case n = 2.

So, we have, $x=\bar{x} \pm 2 \sigma$

The value above is:

x = 473 + 2 $*$ 104 = 681

The value below is:

x = 473 - 2 $*$ 104 = 265

Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.

Prove that: (a2 - b2)3 + (b2-c2)3+ (c2-a2)3 = 3 (a+b) (b+c) (c+a) (a-b) (b-c) (c-a).

Solve the equation. Show your work. 45 = 3b + 69

Cerrena [4.2K]

There should be no problem in finding the value of the unknown variable "b" in the equation given in the question.The equation is solvable for finding the value of "b" because it is the only unknown variable in the single equation that is given in the question.
45 = 3b + 69
Let us reverse both sides of the equation first. then, we get
3b + 69 = 45
3b = 45 - 69
3b = - 24
b = - (24/3)
= - 8
So from the above deduction, we can easily conclude that the value of b in the given equation is -8.
