<span>Residents who are under 25 years and those above are mutually exclusive.
Let V = number of persons who take Vanilla under 25yrs and V' be the number of residents who are at least 25yrs who take Vanilla.
Okay, so P(V) = 40/150 and P(V') = 15/150
P(V or V') = 40/150 + 15/150 = 0.366</span>
Try 21 if its wrong sorry im not very smart
Answer:
(x+3)(x−5)
Step-by-step explanation:
to factor, simply just think of what two numbers multiplied together would give you -15 but added together give you -2. since the produce is negative, you know one number is positive, and one is negative, and since the sum is also negative, you know that the larger root is negative
The answer would be 5z i think
Answer:
Step-by-step explanation:
LA = pi*r*l = 3.14*8.5*12.4 = 331
SA = LA + pi*r^2 = 331 + 3.14*8.5^2 = 558
V = 1/3*pi*r^2*h = 1/3*3.14*(8.5^2)*sqrt(12.4^2-8.5^2) = 683
