Answer:

Population parameter

Step-by-step explanation:

We are given the following in the question:

74% of all instructors at your school teach 2 or more classes.

Parameter and statistic:

  • Parameter is the value that describes a population.
  • Population is the collection of all the possible observations of an event.
  • Statistic is the quantitative value that describes a sample.
  • A sample is a part of a population and is always smaller than a population.

Population:

all instructors at your school

Parameter:

74% of all the instructors at your school teach 2 or more classes

Thus, 74% describes the population that takes two or more classes.

Hence, it is a population parameter.

What is the value of x?
torisob [31]

Answer:

x=45^{o}

Step by step explanation:

We have been given that measure of angle A is fifty five degrees, the measure of angle B is eighty degrees and the measure of angle C is x.

Since we know that sum of measures of all the three angles of any triangle equals to 180 degrees.

Let us set sum of measures of all angles of our triangle equal to 180 degrees.

A+B+C=180^{o}

Upon substituting our given values in our equation we will get,

55^{o}+80^{o}+x=180^{o}

135^{o}+x=180^{o}

x=180^{o}-135^{o}

x=45^{o}

Therefore, the measure of angle x equals to 45 degrees.

To the nearest degree what is the measure of each exterior angle of a regular dodecagon
malfutka [58]

Answer:

30^{\circ}

Step-by-step explanation:

We are asked to find the measure of each exterior angle of a regular dodecagon.

We know that a regular dodecagon is a 12 sided regular polygon with each side equal.

We know that measure of each angle of n-sided regular polygon can be found using formula:

\text{Each exterior angle}=\frac{360^{\circ}}{n}

Upon substituting n=12 in above formula, we will get:

\text{Each exterior angle of a regular dodecagon}=\frac{360^{\circ}}{12}

\text{Each exterior angle of a regular dodecagon}=30^{\circ}

Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.

93.75<br>x 0.99what's 93.95 * 0.99 ​
Elden [556K]
So 93.95 * 0.99 = ?

First, we need to set up the problem and line up the decimals, It should be like:

9395
x 99


Next, we should multiply as normal.

You should get 930,105.

Third you need to move the decimal how many times behind the numbers of your equation.

93.95= 2 numbers
0.99= 2 numbers, the total is 4 numbers!

So your final answer is 93.0105.

Hope this helps, have a great evening!! :)
