<span>The probability that a house in an urban area will develop a leak is 55%. if 20 houses are randomly selected, what is the probability that none of the houses will develop a leak? round to the nearest thousandth.
Use binomial distribution, since probability of developing a leak, p=0.55 is assumed constant, and
n=20, x=0
and assuming leaks are developed independently between houses,
P(X=x)
=C(n,0)p^x* (1-p)^(n-x)
=C(20,0)0.55^0 * (0.45^20)
=1*1*0.45^20
=1.159*10^(-7)
=0.000

Total Volume of pepsi in this pack of 12 is 244.3308 in³.
Given:
12 Cylindrical can
radius of 1.25 in
height of 4.15 in
Find total volume:
Volume = π r² h where π = 3.14
V = 3.14 * (1.25in)² * 4.15 in
V = 3.14 * 1.5625 in² * 4.15 in
V = 20.3609 in³
Volume of 20.3609 in³ is only good for one can. There are 12 cans.
Total Volume = 20.3609 in³ x 12 cans = 244.3308 in³
The triangle is isosceles so m∠A and m∠C are the same.
So to find ∠B, we do 74 + 74 + b = 180
148 + b = 180
b = 180 - 148
b = 32
Answer B is the right choice.
X equal 5/3 set it equal to zero and slove
