Answer: x=−3 or x=13
Step-by-step explanation:
Step 1: Subtract 39 from both sides.
x2−10x−39=39−39
x2−10x−39=0
Step 2: Factor left side of equation.
(x+3)(x−13)=0
Step 3: Set factors equal to 0.
x+3=0 or x−13=0
x=−3 or x=13
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%
