Answer: The area of the circular wooden table = 50.24 ft²
Step-by-step explanation:
Given: The radius of the circular table = 4 feet
We know that area of a circle is given by :-

Therefore, the area of circular wooden table is given by :-

The area of the circular wooden table = 50.24 ft²
Answer:

And we can use the probability mass function and we got:
And replacing we got:

Step-by-step explanation:
Let X the random variable of interest "number of graduates who enroll in college", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:

And we can use the complement rule and we got:

And we can use the probability mass function and we got:
And replacing we got:

Answer:
Step-by-step explanation:
+ we take t- number of tickets and each ticket cost $7.
So t is too the number of people who buy tickets, then

A) We can calculate the amount of money: M= 7t where 
B) The domain for t is
, t is an integer.
C) The range for the amount M:

Answer: 83.5
Step-by-step explanation:
We want to find the value that makes

To find it we must look at the standard normal table, using the complementary cumulative table we find that

Then, using the z-score we can find the minimum score needed, remember that

Where
σ = standard deviation
μ = mean
And in our example, x = minimum score needed, therefore

Rounding to the nearest integer the minimum score needed is 568, if you get 568 you are at the top 20.1%.
