as a busboy, he will earn $81.25
and as a clerk, he will earn, $100 if he works for 12.5 hours a week which is $181 a week.
Answer:
z = - .5
Step-by-step explanation:
z = (x - μ)/ σ
z = 56 - 60/8 = -.5
First compute the component form of vector u by subtracting its initial values from terminal values. 18-1=17, 6-(-12)=18. So u=(17, 18). Since v points in the opposite direction, and has a magnitude three times that of u, we multiply the u by -3 and get v=(-3*17, -3*18)=(-51, -54).
so what you would do is 20 x 12 and see what you get and the subtract it from 900 and then see what number would take you to 900
