Answer: No
Step-by-step explanation:
$12-$4.50= $7.50
$7.50*15= $112.50
The Total cost is $135 She will only be making $112.50 in profits.
890×(1+0.187÷12)^(12)−890×(1+0.125÷12)^(12)
=63.61 saved
Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
Y=600000(1+1.8%)^(x-2000)
So the population in 2012
Y=600,000×(1+0.018)^(2,012−2,000)
Y=743,232
8 total pens....4 are black
first pick, probability of being black is 4/8
2nd pick. without replacing, probability is 3/7
probability of a black pen picked first and then another black pen picked again is : 4/8 * 3/7 = 12/56 = 0.21
