Answer:
Step-by-step explanation:
There is an inverse relationship between the amount on advertisement and average number of bower boats
F(x) = 3x - 2
g(x) = x^2 + 1
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 3x - 2 + x^2 + 1
(f+g)(x) = x^2 + 3x -1
Answer D
Answer:
x minus -5 or -5 minus x

Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
