Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)

Answer:
b. -0.862
Step-by-step explanation:
The only answer choice with a minus sign is B, which is the correct choice.
When the value of interest is below the mean (2800 is below 3550), the z-score will be negative:
z = (2800 -3550)/870 = -750/870 ≈ -0.86207 ≈ -0.862
_____
As always, z is computed as ...
Z = (X -μ)/σ
