You get 25 tickets for $15
all you need to do is take the cost and divide it by the number of tickets.
$15 <span>÷ 25 tickets = $0.60 per ticket</span>
V - E + F = 2.....add E to both sides
V + F = 2 + E ...now subtract 2 from both sides
V + F - 2 = E <==
Answer:$34.50
Step-by-step explanation:
First of all you’re gonna wanna know the total amount for ONE bag of cat food. so divide
11.50/2= 5.75
now add OR multiply (it doesn’t matter) 5.75 six times.
5.75x6= 34.5
hope this helped
Answer:
the expected value of throws is E(Y) = 15 shots
Step-by-step explanation:
We will divide the experiment in 2
first) throw seven fair coins , and you get at least twice as many heads as tails when the number of heads is 6 or 7
being the random variable X=getting x heads , then P(X) has a binomial distribution, with p=0.5 and n=7. then
p₂=P(X≥6) =P(X=6)+ P(X=7)= 0.0546 +0.0078 =0.0624
second) if you get at least twice as many heads as tails when the number of heads , you throw again. then the random variable Y= number of shots in the experiment , then Y follows a negative binomial distribution , with probability of success pn=1-p₂ , and number of failures until the experiment is stopped r=1
then the expected value of throws E(Y) is
E(Y) = pn*r/(1-pn) = (1-p₂)*1/p₂ = 1/p₂ -1 = 1/0.0624 - 1 = 15
E(Y) = 15 shots
