I need help myself lol XD
Answer:
True mathematical statement.
"If x = 0, then for any real number y, we have: y*x = 0."
This is true, and we can prove it with the axioms of the real set.
A false mathematical statement can be:
"if n and x are integer numbers, then n/x is also an integer number."
And a counterexample of this is if we took n = 1 and x = 2, both are integer numbers, so the first part is true, but:
n/x = 1/2 = 0.5 is not an integer number, then the statement is false,
Answer:
The probability that he doesn’t win is 6/(n + 6)
Step-by-step explanation:
Mathematically, the probability that an event occur is 1 minus the probability that the event doe not occur.
Thus, what we are saying here is that the sum of the probabilities that Paul wins the raffle draw and he doesn’t win the raffle draw is 1
This can be mathematically expressed as;
probability that he doesn’t win = 1 - probability that he wins
Thus we have;
1- n/(n+ 6)
= [(n+ 6) -(n)]/(n+6) = 6/n+ 6
- Density of alcohol=79g/ml
- Density of water=100g/ml
We know
- if a object has higher d ensity than water then it would sink in water and if it has lower density than water then it float over water
Clearly
So alcohol would float over water
Answer:
Discrete; number of Months after the first year; amount remaining on the card.
Step-by-step explanation:
The value of the card strictly loses $2.50/month after the first year of purchase. This means that the values can only be $22.50, $20, etc. If it were continuous, it would lose an amount that led up to $2.50, meaning that you could have values such as $23.48 and $24.07. We cannot have these values, therefore the relationship is discrete.
As time passes, the amount of money in the card changes. As the amount of money in the card depends on the number of months, we can say that the number of months is the independent variable while the amount of money on the card is the dependent variable.
Hope this helps.
