G(x) = (1/4)^x
Find g(-3) this means to replace x with -3
G(-3) = (1/4)^-3
Apply the negative exponent rule :
A^-b = 1/a^b
G(-3) = 1/(1/4)^3
G(-3) = 1/ (1/64)
G(-3) = 64
Answer: 64

What math?
Step-by-step explanation:
Answer:
Step-by-step explanation:
The expression is:
First, we will multiply the numerators together and denominators together.
This gives,
Now, we use the exponent property .
This gives,
Now, we use the exponent property
This gives,
From the properties of exponents,
So,
We start with 12 samples with an average of 34 and add two more samples of 34, so the mean remains 34.
For the variance (squared standard deviation) we add up the squared differences between the sample and the mean and divide by n-1=11. With two additional samples exactly at the mean, the sum won't change but now we divide by 13. So our new standard deviation must be
Answer: 4.37
