I need help finishing a question. I used the explanation function on the program, but it didn't specify what to do to get the fi
leva [86]

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337

Add this to 1 and we have 40.75093337

Then divide over 2pi to get a final approximate result of 6.48571248

So x = 6.48571248 is one approximate solution

In short, I computed \frac{1+\sqrt{1+160\pi^2}}{2\pi} only focusing on the plus for now.

----------------------

If you were to compute \frac{1-\sqrt{1+160\pi^2}}{2\pi} you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.

Sum of interior angles of a convex 14-gon
just olya [345]

Answer: 2160°

Step-by-step explanation:

The sum of angles in a polygon is represented by the formula:

Sum = (n - 2) x 180° where n is the number of sides in the polygon

In this case, the complex polygon has 14 sides (n = 14)

So, (14 - 2) x 180°

= 12 x 180°

= 2160°

Thus, the sum of interior angles of a convex 14-gon is 2160°

Pediatricians work an average of 48 h per week. The standard deviation is 12 hours. What percentage of pediatricians work more t
cricket20 [7]

Answer: 2.28 %

Step-by-step explanation:

Given : Mean : \mu=\ 48

Standard deviation :\sigma= 12

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x = 72

z=\dfrac{72-48}{12}=2

The p-value = P(2

1-0.9772498=0.0227502\approx0.0228

In percent, 0.0228\times100=2.28\%

Hence, the  percentage of pediatricians work more than 72 h per​ week = 2.28 %
