I got 20,737 but I could be wrong so I will attach my algorithm and work.
Answer:
Bro math Step-by-step explanation:
The solution for equation is x = -6
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>

We have to solve the equation
According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right
Therefore, solve for brackets in given equation

Solve for terms in left hand side of equation

Move the variables to one side and constants to other side

Thus the solution for equation is x = -6
Given that t<span>he
mean lifespan of a sylvania light bulb is 1600 hours with a standard
deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours.
the lifespan distribution is relatively symmetric.
Since, the distribution is relatively symmetric, the measure of
spread that is the best measurement is the standard deviation.</span>
