Solve for b<br> 2(-2b+3)=9
Alexxx [7]

Answer:

b=-3/4 or b=-0.75

Step-by-step explanation:

2(-2b+3)=9

2b+3=\cfrac{9}{2}

-2b=\cfrac{9}{3} -3

-2b=\cfrac{3}{2}

b=-\cfrac{\frac{3}{2} }{2}

b=-\cfrac{3}{2\times 2}

b=-\cfrac{3}{4}

Hope it helps! :)

PLEASE ANSWER CORRECTLY! WILL GIVE BRAINLIEST!
vaieri [72.5K]

Answer:

0.7938

Step-by-step explanation:

z1 = (125-100)/15 = 1.667

P( < 125) = 0.9522

z2 = (85-100)/15 = -1

P( > 85) = 0.8413

0.9522 + 0.8413 - 1 = 0.7935
