The cost of a plane ticket varies directly as the number of miles in the trip. A 3000 mile trip costs $400. What is the cost of a 450 mile trip
Answers
Answer:
$60
Step-by-step explanation:
set up a proportion and cross-multiply:
3000/400 = cost/450
c = cost
3,000c = 180,000
c = 180/3
c = 60
Price of the ticket of 450 mile trip = $60.
What is Division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. It is an operation used for equal grouping and equal sharing in math. Division is the opposite of multiplication.
Division Math Formula
The four important terms used in the division operation are dividend, divisor, quotient and remainder. The formula to calculate the division of two numbers is:
Dividend ÷ Divisor = Quotient + Remainder.
Given,
Ticket cost of 3000 mile trip = $400
Ticket cost of 1 mile trip = $400/3000
Ticket cost of 450 mile trip = $400 × 450 /3000
= $60
Hence, the cost of 450 mile trip is $60.

10 different names are put into a computer, and one of them is Colin, the computer chooses 2 names at random. The computer is set so that the same name can be chosen twice. What is the probability that Colin is chosen at least once?
Answers
Answer:
0.19
Step-by-step explanation:
Given that :
Total possible outcomes = 10
If the same name can be chosen twice, then probability is with replacement ;
Probability = required outcome / Total possible outcomes
Required outcome = number of Collins in name = 1
Probability of choosing Collins atleast once ;
2[P(Collins) * P(not Collins)] + P(Collins) * P(Collins)
P(colins) = 1/10
P(not Collins) = 9/10
2(1/10 * 9/10) + (1/10 * 1/10)
2(9/100) + (1/100)
18/100 + 1/100
19/100

what is a sequence? How do I determine if a sequence is arithmetic or geometric?
Answers
Answer: Ok So Compute successive differences of the terms. If they are all the same, the sequence is arithmetic and the common difference is the difference you have found. If successive pairs of differences have the same ratio, the sequence is geometric The common pattern in an arithmetic sequence is that the same number is added or subtracted to each number to produce the next number. This is called the common difference. The common pattern in a geometric sequence is that the same number is multiplied or divided to each number to produce the next number.and the common ratio is the ratio you have determined.
