I think the answer is -7 and 5 .

you multiply the first two x’s . that leaves you with x^2 + 2x - 35 = 0 . now you just do simple factoring to get you with (x+7)(x-5) . next , you set those to zero like this : x+7=0 and x-5=0. then you subtract 7 on one , and add 5 to the other to get : x=-7 and x=5 :)

Jet001 [13]
<span>a) 

Z*_Upper = (76 - 62.7)/2.5 = 5.32

Z*_Lower = (57 - 62.7)/2.5 = -2.28 

The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28). 

Use normal distribution table to get the answer for p and multiply with 100 to get the percentage. 

The other questions are now easy for you to answer on your own. Hope it helps.
