Answer:
total amount = n (d-18)
total amount = dn - 18n
Step-by-step explanation:
given data
pay = $18 less than the original price
originally cost = d dollars
sell = n games
solution
we take original price paid for the game = d
and they will pay $18 less than the original price
so that can we say
d -18
and
when sold n games than the cost of n used games will be here
cost = n (d-18)
so it can express as
total amount = n (d-18)
total amount = dn - 18n
Answer:
1 out of 2
Step-by-step explanation:
even though the coin was landing on heads more times than tails it still remains a fifty-fifty chance.
To answer this problem, one way is to use the calculator and add directly the two numbers and get the average between the two. The answer is 25/77. We can also get this number by getting the LCM of the denominators which is 77. 2/7 is equal to 22/77 while 4/11 is equal to 28/77. 0.5*(22 +28) is equal to 25. Hence the answer is 25/77.
Answer:
a)False: In a sample of 100 men who are heavy smokers, exactly 24 of them will contract lung cancer.
b)True: In a sample of 100 men who are heavy smokers, the number who will contract lung cancer is likely to be close to 24.
c)True: As more and more heavy-smoking men are sampled, the proportion who contract lung cancer will approach 0.24. Circle one: TRUE FALSE
