Answer:
the answer is 12 gallons
Step-by-step explanation:
make fractions improper:
9/8 and 25/2
make them have a common denominator:
9/8 and 100/8
to make a whole gallon but what you do to one side you do to the other:
9/8-1/8=8/8
100/8-1/8=99/8
divide 99/8:
12.375
round down:
12
It could be even bc it goes up
Answer:
9/2
Step-by-step explanation:
the number of the equation is 9/2 so the answer must be 9/2
5/2+2/3+n=1/6
5/2=15/6
2/3=4/6
15/6+4/6+n=1/6
19/6+n=1/6
n=1/6-19/6
n=-18/6
n=-3
So, your answer is -3
Answer:
0.9648
Step-by-step explanation:
Given that:
p = 0.2
Sample size = Number of trials (n) = 15
Probability that atleast one person is infected.
This can be solved using the binomial probability function :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x ≥ 1) = p(1) + p(2) + p(3) +... + p(15)
The sum of the individual probabilities of p(1) up to p(15)
Therefore, to save computation time, we can use the binomial probability calculator :
P(x ≥ 1) = 0.9648
