Step-by-step explanation:
You can figure this out using the sine function:

Answer:
She has a total of $3.75 left
Step-by-step explanation:
Step 1
Express the amount of money Luis had in the beginning as follows;
A=E+R
where;
A=initial amount he had at the beginning
E=total expenditure
R=total remainder after spending
In our case;
A=(1×10)+(3×5)=$25
E=Amount spent at amusement park+amount spent on snacks
E=(12.75+8.50)=$21.25
R=unknown=r
Step 2
Substitute the values in the expression and solve for A;
25=21.25+r
r=25-21.25=3.75
r=3.75
She has a total of $3.75 left

Answer:
interquatile range is 20
quartile 1 is 20
quartile 2 is 90
quartile 3 is 100
Step-by-step explanation:
The interquatile range is simply done by separating the numbers into two equal parts(but this method is only for even set of numbers, 6 in your case) so after separating them into two parts
[20,20,80] & [100,100,100] you can find the median(middle value when arranged in order).
so m1 will be 20 and m2 will be 100,
therefore by subtracting m2-m1 you find the interquatile number. 100-20= 80
To find quartiles divide the set into 3 equal parts. for the middle value(q2) you take the average between 80 and 100 which is 90.
