Volume of a cylinder = the area of the base x height of the cylinder
Area of base =
r^2
A = 6^2(
)
A = 36
V = 36
x 12
V = 432
5 cylinders = 5V
5V = 5 x (432
)
5V = 2160
Final answer: Alex needs to buy 2160
or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.
Let x=gallons of 80% solution to be mixed
x+80=gallons go final 70% mixture
..
80%*x+30%*80=70%*(x+80)
.8x+24=.7x+56
.1x=32
x=320
gallons of 80% solution to be mixed=320
Answer:
Step-by-step explanation:
Let X be the length of pregnancy.
X is N(268, 15)
a) Prob of pregnancy lasting 307 days or longer
= P(X>307) = 
=0.5-0.4953
=0.0047
b) Lowest 2% is 2nd percentile
Z=-2.55
X score = 268-2.55(15)
= 229.75 days
If length of days >230 days then it is not premature.
