Answer:
At a certain pizza parlor,36 % of the customers order a pizza containing onions,35 % of the customers order a pizza containing sausage, and 66% order a pizza containing onions or sausage (or both). Find the probability that a customer chosen at random will order a pizza containing both onions and sausage.
Step-by-step explanation:
Hello!
You have the following possible pizza orders:
Onion ⇒ P(on)= 0.36
Sausage ⇒ P(sa)= 0.35
Onions and Sausages ⇒ P(on∪sa)= 0.66
The events "onion" and "sausage" are not mutually exclusive, since you can order a pizza with both toppings.
If two events are not mutually exclusive, you know that:
P(A∪B)= P(A)+P(B)-P(A∩B)
Using the given information you can use that property to calculate the probability of a customer ordering a pizza with onions and sausage:
P(on∪sa)= P(on)+P(sa)-P(on∩sa)
P(on∪sa)+P(on∩sa)= P(on)+P(sa)
P(on∩sa)= P(on)+P(sa)-P(on∪sa)
P(on∩sa)= 0.36+0.35-0.66= 0.05
I hope it helps!
Answer:
Garden Table: $750
Bench: $250
Step-by-step explanation:
Use the system of equation. Let "garden table" = x, and "bench" = y.
x + y = 1000
x = 3y
Solve for each variable. Note that x = 3y. Plug in 3y for x in the first equation:
x + y = 1000
(3y) + y = 1000
Simplify. Combine like terms:
4y = 1000
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 4 from both sides:
(4y)/4 = (1000)/4
y = 1000/4
y = 250
A bench = $250.
Plug in $250 for y in one of the equations:
x = 3(y)
x = 3(250)
x = 750
A garden table = $750
The cost of the bench is $250.

Answer: 369
Step-by-step explanation: bc u times it
Answer:
D.No, because the total earned is $1255.70 per month.
Step-by-step explanation:
Essentially if your cost is 1543 a month, you simply wouldn't be able to afford it.
If you plug in 7.25 and 40 (you get 290) . With this information we plug it into weeks. In a month there are approximately 4.345 weeks (you can just times 290 by
4.34) which gives the stated result in the answer choice.
A person would not be able to live here and cover other expenses if they worked 7.25 for 40 hours!
Answer:
x+y < 28
Step-by-step explanation:
1. Look at your variables: x is the first number and y is the second.
2. Know the limits: It says it has to be NO MORE than 28, so the inequality has to be less than (<) 28. And it says that the SUM of 2 numbers (in this case x and y), is no more than 28, so you know there's some addition between the two.
3. Write out your inequality: x+y < 28
