Each dvd cost $7.50 how? Your friends buy 8 dvd's and in total is 60, you want to divide 60 from 8 and find that it's 7.50 and then multiply 8 to 7.50 and it should be 60. Hope this helps!!
Suspecting that his parents are going to give him $1,300 continually you would solve like this
$120,000-$100= $19,900
$19,900/$1,300= 92.23
92.23 is the amount of $1,300 donations it would take from his parents, so if he was getting $1,300 month it would take 92.23 months

Answer:
0.0143
Step-by-step explanation:
In this question, we are asked to use the binomial distribution to calculate the probability that 10 or fewer passengers from a sample of MIT data project sample were on American airline flights.
We proceed as follows;
The probability that a passenger was an American flight is 15.5%= 15.55/100 = 0.155
Let’s call this probability p
The probability that he/she isn’t on the flight, let’s call this q
q =1 - p= 0.845
Sample size, n = 155
P(X < A) = P(Z < (A - mean)/standard deviation)
Mean = np
= 125 x 0.155
= 19.375
Standard deviation = √npq
= √ (125 x 0.155x 0.845)
= 4.0462
P(10 or fewer passengers were on American Airline flights) = P(X \leq 10)
= P(Z < (10.5 - 19.375)/4.0462)
= P(Z < -2.19)
= 0.0143
Answer:
7 horses and 8 chickens
Step-by-step explanation:
To solve this, first you would need to list out all of the available ratios. Then, find out how many legs are in each option.:
14 horses and 1 chicken = 58 legs
13 horses and 2 chickens = 56 legs
12 horses and 3 chickens = etc.
11 horses and 4 chickens
10 horses and 5 chickens
9 horses and 6 chickens
8 horses and 7 chickens
7 horses and 8 chickens = 44 legs!
6 horses and 9 chickens
5 horses and 10 chickens
4 horses and 11 chickens
3 horses and 12 chickens
2 horses and 13 chickens
1 horses and 14 chickens
