The 4-digit PIN for one of my credit cards consists of four different digits. The sum of the first two digits is 12 and the sum of the last two digits is 15.

Which one of the following additional pieces of information is sufficient by itself to enable deduction that the PIN is 7569?

A. Second digit × third digit = 30
B. Fourth digit – first digit = 2
C. Third digit – second digit = 1
D. First digit × fourth digit = 63

Answers

Answer 1

Answer:

D or A

Explanation:

I think the additional piece of information that is most sufficient is D because the only numbers that are single digits and make 63 are 7 and 9. So we know the first digit is 7 and the next digit must be 5 to sum up to 12 and for 9, the third digit must be 6.

But, it could also be A, the only numbers that are single digits of that have the product of 30 are 5 and 6. Likewise 7 being the first digit to make 12 and 9 being the last to sum up to 15.

Hope this helps, but of course this is my opinion so I might be wrong or right.

Give me 6 main reasons why the drinking age should be lowered to 18

Answers

Answer:

If the legal drinking age was lowered to 18, people wouldn't have to jeopardize their futures by obtaining and using false identifications. Many underage drinkers will quickly consume larger amounts of alcohol prior to going out instead of drinking over an extended period of time. It would reduce the abuse of alcohol among young people. Proponents of lowering the minimum legal drinking age (MLDA) from 21 argue that it has not stopped teen drinking, and has instead pushed underage binge drinking into private and less controlled environments, leading to more health and life-endangering behavior by teens.

Fully simplify your answer. Last year, the Galaxy Fair Amusement Park installed a family roller coaster they named The Twist. This coaster was designed to accommodate riders from age 4 to adult and features a tall climb hill and several banking turns. Overall, the park has been disappointed in the reception of The Twist, and very few families are riding the coaster this season. After some research, they discovered that park guests think the climb hill is too tall and fast for younger riders. Galaxy Fair Amusement Park has asked a roller coaster design firm to help them redesign The Twist during the coming off season. The quadratic function that represents the current climb hill is () = 0.102 + 3.6 2.4 and the quadratic function that represents the proposed redesign of the climb hill is () = 0.032 + 1.62 6.87. In these functions, the value of x represents the time, in seconds, since the roller coaster train cars have left the station, and the output variable is the height of the roller coaster track, in feet, above the ground. 1.
