C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X

It’d be 0.57, hope this helps.
Isn't the "Property of Subtraction,"?
Answer:
308
Step-by-step explanation:
Answer:
a) y=1/3 sqrt(x+1)
b) 2/3
c) 224
Step-by-step explanation:
a) y varies directly to sqrt(x+1)
means there is some constant k such that y=ksqrt(x+1)
y=1 when x=8 (plug this in and find k) 1=ksqrt(8+1)
1=ksqrt(9)
1=k(3)
1/3=k
So the equation is y=1/3 * sqrt(x+1)
a) y=1/3 *sqrt(x+1)
b) what is y when x=3 if you have y=1/3 * sqrt(x+1)
Plug in 3 for x
y=1/3 *sqrt(3+1)
y=1/3 *sqrt(4)
y=1/3 *2
y=2/3
b) 2/3
c) what is x when y=5
Plug in 5 for y
5=1/3 *sqrt(x+1)
multiply both sides by 3
15=sqrt(x+1)
square both sides
225=x+1
subtract 1 on both sides
224=x
c) 224
