The answer is d....
I hope this helps
Let the constant be k.
For an inverse squared proportion the formula is y = k/x^2
Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48

So,
a parallelogram is forming here
then, opposite angels are going to be equal
so,
y = (x+50)°
now,
as you know that sum of all angles of a quadrulateral equals 360°
so,
2 {(x+50)+(x-30)}=360°
(x+50)+(x-30) = 180°
2x + 20 = 180
2x = 160
x = 80°
therefore,
angle y = (x+50) = 80 +50 = 130°
and x = (x-30) = 80 - 30 = 50°
Answer:
Option ii is right
Step-by-step explanation:
Given that according to the U.S. Department of Education, approximately 57% of students attending colleges in the U.S. are female.

(Two tailed test at 5% significance level)
Test statistic =1.42
Here since proportions we use Z test
p value = 0.156
(ii) P-value =0.156
