Answer:
3 1/2
Step-by-step explanation:
The ratio 11:4 means that the total number of spaces is a multiple of 15 parts, this multiple is what value is assigned to each part.
450/15=30 so each part is equal to 30 spaces
Full sized car spaces are 11*30=330 spaces
Compact car spaces are 4*30=120 spaces.
The solution to the problem is 16.
first, you must set up the equation.

Then, simplify exponents.
256*
Next, simplify the equation.
16
Answer:
The mean of X is 122.5 and the standard deviation is 7.9.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

In this problem, we have that:

So


The mean of X is 122.5 and the standard deviation is 7.9.
Answer:
Exponential form: y = x^½
Step-by-step explanation:
Given

Required:
The exponential form
To convert to an exponential function, we have to take exponents of both sides using the base of the logarithm function.
This gives us

Since the base of the exponential function and the logarithm is the same (x), they'll cancel out one another
This leaves us with

Hence, the exponential form of the expression
is
