It dont matter. Nvm

I know him irl. Were at school rn. He got us blocked from it but now he is back. 

Cphill your admin. Shut  down his acc or something. 

It is i know him irl. Were at math class rn. 

sorry. I'm still non-binary thats my buisness.

Not as difficult as it first seems......

From O, bisect chord CD  and call the point of bisection, E

When a chord is bisected by  segment drawn from a circle's center....the angle formed is = 90 °

So...ED = 4  and OD  = 6

So OED is a right triangle with angle OED = 90  and ED a leg and OD the hypotenuse  ....so.... OE  =  sqrt[ OD^2 - ED^2 ] =  sqrt [ 6^2 - 4^2]  = sqrt [ 20]  = 2sqrt(5)  =  the height of  obtuse triangle KCD

And the base of KCD  = CD  = 8

So....the area of KCD  =

(1/2)* base * height  =

(1/2 ) * 8 * 2 sqrt (5)  =

[ 8 sqrt (5)  ]  units^2

He is the same person as iamjeff

DUDE im not female! I'm non-binary... How much do I have to tell you.

im not a female!

Look at your Negative z-score table .....look for a number close to 16% (.16)

I find   .99 z score is .1611

.99 x  standard deviation = .99 x 4 ~~ 4           73 - 4 = 69 

This question was submitted earlier ....it has an error in it somewhere

If we use  1.6%    look for number    .016 -ish      z -score -2.14

73  - 2.14 x 4 = 64.44     so I would go with the answer    'Scores below 65'     if it really is 1.6%    and not 16%

Or as Rom points out ....maybe it is the opposite end of the spectrum...the TOP 16% (and we were looking at it from the wrong perspective)

100% -16% = 84     look at positive z-score table for   .84 -ish  approx 1.0 standard deviations ABOVE the mean

      73 + 1 Standard deviation = 73+4 = 77 --------> choice #3   

    Thanx Rom!

quick rule of thumb

16% of the population is a z-score of -1, i.e. 1 sigma less than the mean.

\(\dfrac{x - \mu}{\sigma} = -1 \Rightarrow x = \mu - \sigma\)

So we would have scores less than 73-4 = 69 being 16%

This doesn't match any of the choices so we note that it could be the top 16% in which case the z-score is 1 and we have

scores greater than x = 73+4 = 77 being 16%

this matches the 3rd choice.

thank you!!!

You go ahead you jack-a**. You are a serious Bi*** you know that. The world would be better without you.  You treat girls the wrong way.

whatever. What did we do?

I've got -8 as the right answer thanks a mill.👍👍🙏
