- 18
2- 20
= -18
Because you do the same thing just going to end up with a negative.
Answer:
0.0475
Step-by-step explanation:
First find the z-score.
z = (x − μ) / σ
z = (125 − 100) / 15
z = 1.67
Use a calculator or chart to find the probability. Using a chart:
P(Z > 1.67) = 1 − P(Z < 1.67)
P(Z > 1.67) = 1 − 0.9525
P(Z > 1.67) = 0.0475
Add both together by combing like terms to get 8x^2-x-4
Answer:
Don't know tbh
Step-by-step explanation:
First add +2z on each side to cancel out the z on the left. then from there do the same on each side.
We have cos( x - y ) = cosxcoy + sinxsiny <=> cos ( π - x ) = cosπcosx + sinπsinx <=> cos ( π - x ) = (-1)cosx + 0sinx = -cosx;
