Answer:
18 pounds = 48 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas
18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas
Step-by-step explanation:
1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)
2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)
3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)

Hi there!
We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:
Now, we know through the distributive property that we can distribute the 
to everything in the parenthesis. Once this is done, we get:
Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together 
. This then would make our equation:
Giving us for our final answer:
Hope this helps!
Answer:
SAY THIS : oh finally i thought u were blind for a sec there
Step-by-step explanation:
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
