Answer:
ans.
Step-by-step explanation:
50.24 square feet is the answer
Sample space = HHH, HHT, HTH, THH, TTT, TTH, THT, HTT (8 possibilities)
Desirable outcomes = TTH, THT, TTH (3 possibilities)
Required probability = 3/8
It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.
<h3>How to calculate the hourly delivery rate</h3>
Your information is incomplete. Therefore, an overview of the information will be given.
In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.
In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:
= $2000/240
= $8.33 per hour

To find the solution, we use the substitution method.
x+y=-1
<span>x-3y=11
</span>
x+y = -1-y
-y
x = -1-y
Now apply the value of x into the other equation.
x-3y=11
-1-y-3y = 11
Combine like terms
-4y -1 = 11
+1 +1
-4y = 12
-4y = 12
-4y/-4 = 12/-4
y = -3
Now, apply the value of Y to one equation to find x.
y = -3
x -3 = -1
+3 +3
x= 2
Now we have the value for both, x and y.
x = 2
y =-3
