Answer:
60, 75
150 165
240 255
330 345
Step-by-step explanation:
csc 4 theta = -2 sqrt(3)/3
Write in terms of sin
1/ sin (4 theta) = -2 sqrt(3)/3
Using cross products
-2 sqrt(3) = 3 sin (4 theta)
Divide each side by 3
-2 sqrt(3)/3 = sin (4 theta)
Take the inverse sin on each side
sin ^ -1(-2 sqrt(3)/3) = sin ^ -1 (sin (4 theta))
240 +360n = 4 theta
and 300 +360n = 4 theta where n is an integer
Dividing each side by 4
240/4 +360n/4 = 4/4 theta and 300/4 +360n/4 = 4/4 theta
60 + 90n = theta and 75 +90n = theta
We want all the values between 0 and 360
Let n=0
60, 75
n=1
60+90=150 and 75+90 =165
n=2
60+180= 240 75+180=255
n=3
60+270 = 330 75+ 270 =345
The given graph shows the relationship between the social media posts and grade point average of different students in Brent's class.
From the given graph, we can say that the grade point average of students decrease with increase in number of their social media posts.
Since grade point average decreases approximately linearly with increase in use of social media posts, It is Strong negative correlation.
Hence, option D is correct i.e. Strong Negative Correlation.

Answer:
60
Step-by-step explanation:
if 3 represents 5% and we know 5%*20 =100% then
3*20=60 represents 100%
