The interior angles of a polygon add to 180°

3x - 11 + x - 8 + 2x + 7 + x + x + 8 = 180
8x - 4 = 180
8x = 184
x = 23

Answer:

f(1) = -3 f(n) = 2 f(n - 1) + 1 f(2)

Alternate form:

{f(n) = -f(1)/3, f(n - 1) = f(1)/2 - f(2)/2}

<h3>Answer:</h3>

40

<h3>Step-by-step explanation:</h3>

The average of a data set is the number "in the middle" of all of the numbers. This is a measurement of the center of a data set. Another word for average is mean.

How to Calculate the Average

The average or mean is calculated by adding all of the values together. Then, divide this sum by the number of data points. For example, if the sum of 5 different data points is 10, then the average would be 10/5.

Finding the Average

Now, let's find the average of this specific data set. First, add all of the data together.

  • 30+35+40+41+42+45+47 = 280

Then, count the number of terms. There are 7 different terms within this data set. So, next divide the sum by the number of terms.

  • 280/7 = 40

This means that the average of the set is 40.

Other Measurements of Center

The mean is not the only measurement of center. There are 3 common measures of center.

  • The mean is found by adding all the terms and then dividing by the number of terms.
  • Another measurement is the median is found by ordering the terms from least to greatest, and then taking whatever number is left in the middle. The median of this set is 41.
  • Finally, the mode is the term that appears the most often. Many times there can be more than one mode. This set has no real mode because all of the terms only appear once.

Tickets to a sporting event cost $125 each. What's a reasonable domain and range.
djverab [1.8K]

The domain and the range of a function is the set of input and output values of the function.

The domain is the set of all whole numbers.

The range is the set of all whole numbers.

Let the number of tickets be x, and the revenue be y.

So, the revenue function will be:

y = 125

The number of tickets cannot be less than 0.

So, the domain of the revenue function is

domain=0,∞

The above means that, the domain is the set of all whole numbers

Similarly, the revenue cannot be less than 0.

So, the range of the revenue function is

range = 0,∞

The above means that, the range is also the set of all whole numbers (in multiples of 125).

a) A group of 50 people are going to run a race. The top three runners earn gold, silver, and bronze medals. b) Creating a nine
rjkz [21]

a) n (No. of peoples) = 50

r (No. of prizes) = 3

p(n,r) = p (50,3)

\begin{gathered} P(n,r)=\frac{n!}{(n-r)!} \\ P(50,3)=\frac{50!}{(50-3)!} \\ =117600 \end{gathered}

b) n(No. of players)=14

r (No. of players for Batting)=9

\begin{gathered} P(14,9)=\frac{14!}{(14-9)!} \\ =726485760 \end{gathered}

c)n(Total applicants)=30

r(tester positions)=4

\begin{gathered} P(30,4)=\frac{30!}{(30-4)!} \\ \text{              =}\frac{30!}{26!} \\ \text{              =657720} \end{gathered}
