Since the variable x is at the exponent, this is an exponential function.
To decide whether an exponential function is a growing or decaying one, we have to look at the base of the exponent.
If the base is between 0 and 1, we have exponential decay
If the base is larger than 1, we have exponential growth.
In your case the base is 3, which is larger than 1, so you have exponential growth.
Thus, <u>option d</u> is your answer
Answer:
a) 27
b) 15
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean of the uniform distribution is:

The variance of the uniform distribution is given by:

The standard deviation is the square root of the variance.
They can be said to follow a Uniform distribution from 1 to 53
This means that 
a. The mean of this distribution is

b. The standard deviation is:

The maximum possible length it could have been is 38.9
Answer:
B
Step-by-step explanation:
Answer:
9/8
Step-by-step explanation:
to divide by a fraction multiply by the reciprocal of the fraction
3/4×3/2
multiply the fractions
3/4×3/2
3×3=9
4×2=8
9/8 is your answer
