By normal curve symmetry
<span>from normal table </span>
<span>we have z = 1.15 , z = -1.15 </span>
<span>z = (x - mean) / sigma </span>
<span>1.15 = (x - 150) / 25 </span>
<span>x = 178.75 </span>
<span>z = (x - mean) / sigma </span>
<span>-1.15 = (x - 150) / 25 </span>
<span>x = 121.25 </span>
<span>interval is (121.25 , 178.75) </span>
<span>Pr((121.25-150)/25 < x < (178.75-150)/25) </span>
<span>is about 75%</span>
A ratio that is equivalent to 8/3 is 16/6.
Because:- 8*2= 16
3*2=6
16/6 is equivalent to 8/3
Writing a proportion:-
8/3=16/6
Answer:
Subtract 5 from each side
Step-by-step explanation:
This would put all coefficients on one side.
Please excuse my sloppy writing but the answer is 30
