Use symmetry and find z so that probability is:
(100-39)/2
=61%
=30.5%~0.305
From the z-table:
z=-0.51
Answer: -0.51

Answer:

Value of Z =0.51

Step-by-step explanation:

Given that P(-z<0<z) = 0.39

Or P(0<z) = 0.39/2 = 0.195

From standard normal table we find that

0.51 satisfies that

P(0<z<0.51) = 0.195

Hence value of z = 0.51

I need help solving this problem.
madam [21]

(f+g-k)(x) means to add the equations f(x) and g(x) then subtract k(x)

2x^2 + 3x + 4x - 9 = 2x^2 +7x -9

2x^2 + 7x - 9 - x^2 -7x = x^2 -9

The answer is : x^2 - 9
