I need more information to answer this question.
Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
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.
Two fractions between 3/5 and 4/5 are 13/20 and 11/15
