Answer:
the probability that the woman is taller than the man is  0.1423
Step-by-step explanation:
Given that :
 the men's heights are normally distributed with mean  68
  68 
standard deviation  = 3.1
   = 3.1 
And
the women's heights are normally distributed with mean  65
  65
standard deviation  = 2.8
   = 2.8
We are to find the probability that the woman is taller than the man.
For woman now:
mean   = 65
 = 65
standard deviation  = 2.8
 = 2.8

![\\ 1 -p  \ P[(x - \mu ) / \sigma < (68-25)/ 2.8]](https://tex.z-dn.net/?f=%5C%5C%201%20-p%20%20%5C%20P%5B%28x%20-%20%5Cmu%20%29%20%2F%20%5Csigma%20%3C%20%2868-25%29%2F%202.8%5D)
= 1-P (z , 1.07)
Using z table,
= 1 - 0.8577
= 0.1423
Thus, the probability that the woman is taller than the man is  0.1423

Answer:
 3^x + 12x -4
Step-by-step explanation:
f(x) = 3^x + 10x
 g(x) = 2x - 4, 
(f + g)(x) = 3^x + 10x +  2x - 4
Combine like terms
              = 3^x + 12x -4
