Sub x = 2-y^2 to Q, we get:
Q = 3(2-y^2)*y^2
let y^2 = k
Q = 3(2-k)k = 3(2k-k^2)
2k-k^2 has a max when k = 1
Then y^2 = 1 -> y = 1 or -1

four segments measure 16, 19, 43 and 50 centimeters. what is the probability that a triangle can be formed if three of these seg
neonofarm [45]
OK, a triangle first of all needs to have a certain condition satisfied. The length of one side of a triangle can not equal the length of 2 sides combined. So in a triangle a + b = c, a + b can not be less than c (a + b <span>≮ c</span>). Therefore, there are only a few possibilities that will work here. Let's find them:

16, 19, 43; no

16, 19, 50; no

16, 43, 50; yes

19, 43, 50; yes 

Since only 2 out of 4 form triangles, there is a 50% chance you'll pick the right segments to form a triangle.

Helga [31]
To find the fraction of the grouo that passed both exams, we need to first convert 75% into a fraction:

75%
=75/100
=3/4

We can then mutiply the fraction above by the students who passed the psychological exam:

3/4×3/5
=9/20

Therefore the answer is 9/20.

Hope it helps!
