Answer:
480 people
Step-by-step explanation:
Set up an equation where x is the number of people surveyed:
180 = (x)(0.375)
Solve for x:
180 = (x)(0.375)
480 = x
So, Annette surveyed 480 people
Answer:
40
Step-by-step explanation:
Plug in 12 for u, 7 for x, and 4 for y in the given expression:
u + xy = 12 + (7)(4)
Remember to follow PEMDAS. First, multiply, and then add:
u + xy = 12 + (7 * 4) = 12 + (28) = 40
40 is your answer.

So we know there are 5 red and 12 silver marbles, together making 16 marbles.
This would mean that there is a 5/17 chance of choosing a red marble.
When you do the math to convert 5/17 into a decimal, it turns into being a .29 chance.
Convert .29 into a decimal, and you know that you have a 29% chance of grabbing a red marble.
Hope this helped!
