In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles
Let's count how many marbles total there are first
8 red + 3 blue + 1 green = 12 marbles total
Now, how many marbles are there that <u>ARE NOT BLUE </u>
8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>
Now<em> let's create a ratio</em> to find a probility
9/12
This can be simplified to 3/4 by taking out the common factor of 3
Your answer is D! "three-fourths"

Hope this helps
The solution to the problem is as follows:
<span>Write the decimal number as a fraction
(over 1)
0.336 = 0.336 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 0.336 × 10 × 10 × 10 = 336
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 336 / 1000
Simplifying our fraction
= 336/1000
= 42/125</span>
Answer:
Step-by-step explanation:
<u>The side of the square is w/2, then its area is:</u>
<u>The shaded area is the difference of areas of the rectangle and the square:</u>
<u>This can be simplified:</u>
- 56w - w² = 336
- w² - 56w + 336 = 0
Answer: y = 20x+75
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
The cost (y) must be equal to the product of the cost per hour of installation (20) and the number of hours that it takes (x); plus the fixed cost of parts and installation (75).
Mathematically speaking:
y = 20x+75
