Step-by-step explanation:

The formula for calculating the sum of interior angles is ( n − 2 ) * 180 ∘ where n is the number of sides.

1) (4 - 2) * 180 = 360 therefore X + 100 + 118 + 53 = 360  =>  X = 360 - 100 - 118 - 53 = 89   =>   X = 89

2) (5 - 2) * 180 = 540  => 90 + 90 + X + 128 + X = 540 => 2*X = 540 - 90 - 90 - 128 = 232   =>   X = 116

3) (6 - 2) * 180 = 720 => 101 + 126 + X + 96 + 147 + 135 = 720 => X = 720 - 101 - 126 - 96 - 147 - 135 = 115   =>   X = 115

4) (9 - 2) * 180 = 7 * 180, since all angles are equal the answer is 7 * 180 / 9 = 7 * 20 = 140    =>   X = 140

5) (5 - 2) * 180 = 540 => 90 + 131 + 102 + X + 145 = 540 => X = 540 - 90 - 131 - 102 - 145 = 72   =>   X = 72

6) Since the sum of the linear pair angles equal 180, X = 180 - 70 = 110 => X = 110

7) (4 - 2) * 180 = 360; Linear pair angle for 73 is 180 - 73 = 107, that means X + 102 + 39 + 107 = 360  =>  X = 360 - 102 - 39 - 107 = 112   =>   X = 112

8) (5 - 2) * 180 = 540;  Linear pair angle for 84 is 180 - 84 = 96;  Linear pair angle for 79 is 180 - 79 = 101;  Linear pair angle for 34 is 180 - 34 = 146; so X + 90 + 96 + 101 + 146 = 540   =>   X = 540 - 90 - 96 - 101 - 146 = 107  => X = 107

Hello and good day.

I will help you solve this question with reasonable explanation, lets start.

The volume consists of Length times height times width.

You can divide this prism into 2 prisms or calculate the prism without the missing space, and subtract the volume of the missing space at the end.

I will show you the last way.

So first lets find the volume of the rectangular prism with out the gap:

5 times 6 times 8

this is a total of 240 cubic units

now lets find the volume of the missing space;

4 times 4 times 5

this is a total of 80.

Now we will subtract 80 cubic centimeters from the rectangle with the space filled in. This results in 160 cubic meters.

The answer is C., 160 cubic meters.

Have a great day, and i hope this helps you.

I think it’s

C. 160 cubic units

The function f(x) after evaluation at {x} = 2 is equal to 67.

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to evaluate the function f(x) = x⁴ + 6x³ + 3 at {x} = 2.

The given function is -

f(x) = x⁴ + 6x³ + 3

Now, for {x} = 2, we can write that -

f(2) = 2⁴ + 6(2)³ + 3

f(2) = 16 + 6 x 8 + 3

f(2) = 16 + 48 + 3

f(2) = 67

Therefore, the function f(x) after evaluation at {x} = 2 is equal to 67.

Find the range & interquartile range of the data set represented by this box plot.

Answers

Answer:

60 and 25

Step-by-step explanation:

The range is the difference between the maximum value and the minimum value.

maximum value = 125, minimum value = 65

range = 125 - 65 = 60

------------------------------------------

The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁

Q₃ is the value at the right side of the box = 115

Q₁ is the value at the left side of the box = 90

interquartile range = 115 - 90 = 25

You will validate the numbers and calculate the average of all of the valid numbers.Your program will read in a file with numbers. The numbers will be of type double.The numbers should be in the range from 0 to 110 (inclusive). You need to count all of the numbers between 0 and 110. You also need to calculate the average of these numbers.If a number is not valid (that is, it is less than 0 or greater than 110) you need to count it (as a count of invalid values) and you need to write out the number to a file called "invalid-numbers.txt". Values written to file invalid-numbers.txt should be in fixed format with two digits to the right of the decimal point.As you did in lab lesson 7 part 1 you need to read in the input file name using cin.The output from your program will be written to cout. The output must contain the file being processed, the total number of values read in from the file, the number of invalid values read in, the number of valid values read in.The last thing you need to output is either the average of the valid values or an error message. The average must have two digits of precision to the right of the decimal point and must be in fixed format. If there is not valid average you should output the message:An average cannot be calculatedIn what case would you display this message?If the input file cannot be opened, you will need to output a message. Assume the input file name is badinput.txt and it cannot be opened. You will display the following error message to coutFile "badinput.txt" could not be opened Here is an example of a working program:Assume the file name read in from cin is:input.txtand that input.txt contains:-12098.5100105.593.58875-311189-12Your program would output the following:Reading from file "input.txt"Total values: 12Invalid values: 4Valid values: 8Average of valid values: 81.19The contents written out to file invalid-numbers.txt are:-12-3111-12You are reading from an input file and you are writing to an output file. Make sure you close both files after you are finished using them. You must do this in your program, you cannot just let the operating system close the files for you.For tests where there is output written to an output file the contents of the output file will determine if you passed that test or not. For cases where you have written out to cout the tests will check the output sent to cout. In some cases output will be written to a file and to cout. When this is the case the test will be run twice with the same input. Once to test cout and once to test the contents of the output file. An example of this would be tests 2 and 3. Both use the same input file. Test 2 check the output written to cout and test 3 checks the output written to the file invalid-numbers.txt. I NEED PICTURES OF THE GREAT HORNED OWLS HABITAT ASAP!!
