Answer:
A single cheeseburger order cost $1.23
A single fries order cost $1.28
Step-by-step explanation:
Let the cost of cheeseburgers be c and the cost of fries be f
Mathematically;
4c + 3f = 10.75 ••••(i)
Secondly;
5c + 2f = 11.2 ••••(ii)
We have two equations to solve simultaneously;
Multiply i by 2 and ii by 3
8c + 6f = 21.5
15c + 6f = 33.6
Subtract ii from i
-7c = -12.1
c = 1.73
Recall;
5c + 2f = 11.2
5(1.73) + 2f = 11.2
2f = 11.2-8.65
2f = 2.55
f = 2.55/2
f = 1.28

Answer:
Given the information in the attached image;
The number of blue marbles is 5.
The total number of marbles is 10.
So, the probability of drawing blue as the first marble is;
Also, since there is a replacement, the probability of drawing blue as the second marble is;
the probability of drawing two blue marbles will be;
Therefore, the probability of drawing two blue marbles is;
Step-by-step explanation:
Letting the variable x approach 1 will give us , an indeterminate result. In such a case, we can use L'Hopital's rule where
Let and
We can see that
and
Applying L'Hopital's rule, we get
Therefore, as the given expression approaches .
