Answer:
2 dollars for kids
5 dollars for adults
Step-by-step explanation:
We will let x= children
y= adult
we know that
33x+42y=276
46x+40y=292
There are a lot of ways you can solve this but I think it's easiest if we use (what I think is called elimination)
we will start by mulitiplying the second equation by 1.05 to get
48.3x+42y= 306.6
We will subtract the first equation from the second to get
15.3x= 30.6
Solve for x and get 2
Now that we know what x equals we can plug that into any equation and solve for y
we have
33(2)+42y=276
y=5

Answer:
A; 4,6,8
Step-by-step explanation:
The ordered pair in roaster form {(2,8), (3, 12), (4, 16), (5, 20)} is a function.
<h3>What is the domain and range of a function?</h3>
Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
We know a function can be many one which means different inputs leads to same output but one to many is not a function as same input can not lead to different outputs.
{(2,8), (3, 12), (4, 16), (5, 20)} is a function as each different input leads to a different output.

Answer:
Option B.
Step-by-step explanation:
From the given venn diagram it is clear that
Since the intersection of A and B is non-empty, therefore by conditional probability
Therefore, the correct option is B.
