There is a 3% chance of each light bulb being defective, and we only want 5 of them to be defective. The chance is then:
Or this really small number: 1.13474853e-8
P(NYPD ∪ CSI ) = 0.6 + 0.7 - 0.4 = 0.9
P(neither) = 1 - 0.9 = 0.1
Answer: 0.1
Lets t time and c the calories burned p pound burns
p= c/t
155lb=500cal/1h
1lb= 3500 cal
30-5 =25 min of workout 25/60= 5/12 hr
1/t=c/5/12
1 lb =3500 cal
500/1=c/5/12
c=208 cal
3500/t=208/(5/12)
3500/t=500
t= 7 min to burn 1 pound calorie
Answer:
18.
Step-by-step explanation:
1) formula of the perimeter given in the condition is:
p=2(VW+XV) or p=2(VY+XY).
Note, VW=XY and XV=VY;
2) if to substitute p=84, VW=2z+2 and XV=3z into the formula above, then
2(2z+2+3z)=84, ⇔ 5z+2=42; ⇒ z=8.
3) if z=8, then VW=2z+2=2*8+2=18.
Answer:
R = rows
C = columns
The chairs will be arranged in a way such that R * C 70
We know that R 20
70 / 20 = 3.5; however, you can't have half of a chair.
So find all the factors of 70 which don't exceed 20.
1, 70
2, 35
