You can just use the tn formula to solve this tn= t1 + (n-1)d
Answer:
1,498.32
Step-by-step explanation:
1,894.32 - 396.00 = 1,498.32 You subtract 396 from 1,894.32
Answer b. The probability that at least 41 of them like to swim is 33%.
Solution:
The probability of an event is always 1 or 100%
The probability of at most 40 of them like to swim is 67% = 0.67
The probability of at most 40 not swimming = 1 - 0.67 = 0.33
Hence the probability of at least 41 people swimming is 33%.
<h3>What is Probability?</h3>
- The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
- An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
- The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.

Answer:
0 is not an element of an empty set.
Step-by-step explanation:
We are asked to determine whether 0 is not an element of an empty set.
We know that an empty set is an unique set having no elements. The cardinality of an empty set is 0.
Cardinality stands for the count of element is an set. An empty set is denoted by symbols ∅ or { }.
The empty set is like an empty container. The container is there, but nothing is in it.
When 0 is an element of a set, then its cardinality would be 1.
Therefore, 0 is not an element of an empty set.
Answer:
Each person tipped $4.30.
Step-by-step explanation:
We know that the total bill was $51.60. The three people paid a 25% tip, which was split evenly among them.
Since the tip is 25%, it will be 25% of the total. Hence:
The total tip is $12.9.
And since it was evenly split among three people, each person tipped:
Each person tipped $4.30.
