A. 25 = (.5 * 22) + (2 * x)
B. 25 = (.5 * 22) + (2 * x)
25 = 11 + 2x
14 = 2x
7 = x
C. 7
Supplementary angles.
This is because supplementary angles are two angles that add up to 180 degrees, and these two angles would add up to 180 degrees.
The independent events are illustrations of probability, and the value of P(B) is 0.40
<h3>How to determine the value of P(B)?</h3>
The given parameters are:
P(A) = 0.50
P(A and B) = 0.20
Two events A and B are independent, if
P(A and B) = P(A) * P(B)
So, we have:
0.50 * P(B) = 0.20
Divide both sides by 0.50
P(B) = 0.40
Hence, the value of P(B) is 0.40

Option B model shows the percent of beads that are blue.
Solution:
Fraction of beads blue = 
To convert it into percent multiply the fraction by 100.
Cancel the common factors, we get
= 20%
This means total number of boxes 100 and shaded in blue color 20.
Therefore option 2 represents 
.
Hence option B model shows the percent of beads that are blue.
Step-by-step explanation:
let number be x
16x = 14 + x
16x - x = 14
15x = 14
x = 14 ÷ 15
x = 0.9
