social network | proportion

site a: | p= 0.24
site b: | p= 0.30
site c: | p= 0.26
no favorite: | p= 0.20

options--
a-about 0.54
b-about 0.80
c-about 0.20
d-about 0.24

the real answer is about 0.80

Step-by-step explanation:

so it is asking you about what proportion of the population has a favorite social network, and you see that there is a category that is a no favorite and site A B and C are the sites that are favorites. You add 0.24 + 0.30 + 0.26          and you get 0.80. And that is how you get 0.80

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
