(f+g)(x) represents the sum of the two functions f(x) and g(x).
Arrange these functions vertically and add up like terms:
<span> f(x) = 3x + 10
</span><span>+g(x) = 5x - 3
-----------------------
(f+g)(x) = 8x + 7
Please note: You've typed in "</span><span>F(x) = 3x + 10x and g(x) = 5x - 3."
I doubt that F(x) actually equals 3x + 10x. Please ensure that you have copied down the original problem correctly. Come back once you've done that, so that we can finish this problem solution.</span>

Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. The mean of the distribution is given as $403,000 and the standard deviation is $278,000.
-To estimate the probability that a randomly selected house has a value less than $500,000:

Thus, the probability that a randomly selected house has a value less than $500,000 is 0.71
b. -since 40 is larger than or equal to 30, we assume normal distribution.
-The probability can therefore be calculated as:

Hence, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863
Answer:
a,b,d
Step-by-step explanation:
(2x^2 + 4 -x^3) + (-4 x^2 + 6x^3 -2)
Combine like terms:
-2x^2 + 2 + 5x^3
Simplified answer
-2x^2 + 2 + 5x^3
I think, I hope I’m correct and this helped you!
