In order to solve this we'll start by assigning variables to hamburgers and cheeseburgers, since these are what we're trying to find. Lets say x = hamburgers and y = cheeseburgers. So we know two things, we know that x+y= 763 (hamburgers plus cheeseburgers sold equals 763, and we know that y= x+63 (cheeseburgers sold equals 63 more than hamburgers sold). Now we have a system of equations. This can be solved most easily by rearranging each equation to each y, and then set them equal to each other:
x+y=763 -> y=763-x, and we already have y=x+63. Set them equal to each other:
x+63 = 763-x (add x to both sides) -> 2x+63 = 763 (subtract 63 from both sides) -> 2x = 700 (divide both sides by 2) x = 350. So we solved for x, which is hamburgers sold, which is what the question asks for, so your answer is 350 hamburgers were sold on Saturday

Answer:
Step-by-step explanation:
First, lets put this into y=mx+b form.
You can bring the 13x over to the 14, by subtracting and you get -2y=14-13x, or also -2y = -13x + 14
Then you can divide both sides by -2 to get y, and you get
-2y/-2 = -13x/-2 + 14/-2 which is simplified to y=13/2x + (-7) which is
y=13/2x-7

THIS HAS THE SLOPE IN A IMPROPER FRACTION... CHECK IF YOU USE MIXED NUMBERS OR IMPROPER FRACTIONS
the mixed number form is y = 7 1/2 x -7
Hope this helps!
Answer:
If her brother has 40 tickets, the equation will be 3(40)+2=122. jamie will have 122 tickets
If her brother has 50 tickets, the equation will be 3(50)+2=152. jamie will have 152 tickets
If her brother has 60 tickets, the equation will be 3(60)+2= 182. jamie will have 182 tickets.

Answer:
1. 0.9544
2. 0.0228
3. 0.0228
Step-by-step explanation:
The computation is shown below;
As we know that
At Normal distribution
As per the question, the data provided is as follows
Mean = 24.4 minutes
Standard deviation = 6.5 minutes
Based on the above information
P(11.4 < X < 37.4) = P(X < 37.4) - P(X < 11.4)
= P(Z < (37.4 - 24.4) ÷ 6.5) - P(Z < (11.4 - 24.4) ÷ 6.5)
= P(Z < 2) - P(Z < -2)
= 0.9772 - 0.0228
= 0.9544
2. P(X < 11.4) = 0.0228
3. P(X ≥ 37.4) = 1 - P(X < 37.4)
= 1 - 0.9772
= 0.0228
