Answer:
x = -3
Step-by-step explanation:
12 -4x-5x = 39
Combine like terms
12 - 9x = 39
Subtract 12 from each side
12-9x-12 = 39-12
-9x = 27
Divide by -9
-9x/-9 = 27/-9
x = -3
Answer: None of these
Explanation:
f(g(5)) first let’s find g(5)
We know:
g(x) = x - 2
g(5) = 5 - 2
g(5) = 3
Thus, f(g(5)) = f(3) because g(5) = 3
=> f(3) = 3(3) + 10
=> f(3) = 9 + 10
=> f(3) = 19
Therefore, f(g(5)) = 19
The answer is -0.1 I believe
Answer:
The standard error of the mean is 0.02
Step-by-step explanation:
Here, we want to calculate the standard error of the mean.
Mathematically;
standard error of mean = SD/ √n
where SD is the standard deviation and n is the number of samples
From the question, SD = 0.22 and n = 121
Inserting this into the equation
Standard error of the mean = 0.22/√121
= 0.22/11 = 0.02
