The percent data between 6.0 and 6.9 would
be 13.59%. Here’s the complete solution for this specific problem.

<span>z = (X - Mean)/SD </span><span>

<span>z1 = (6 - 5.1)/09 = + 1 </span>

<span>z2 = (6.9 - 5.1)/09 = + 2 </span>

<span>Required Percent = P(6 < X < 6.9)*100 </span>

<span>= P(1 < z < 2)*100 </span>

<span>= [P(z < 2) - P(z < 1)]*100 </span>

<span>= [0.9772 - 0.8413]*100 </span>

<span>= 0.1359*100 </span>

<span>= 13.59%

I am hoping that this has answered your query.</span></span>

Hello,

x^4+4x^3+2x²+x+4=(x²+3x)*(x²+x-1) + 4x+4

Remainder=4x+4

4d-4=5d-8

-4d -4d

-4=d-8

+8 +8

d=4
