Answer 1

Answer:

Hi Kimberlys969pdrfzz,

Question:

Find the mean

Mean - "The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

$(10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28)/(9) = (180)/(9) = 20$

Answer:

Mean = 20

Hope This Helps!

Answer 2

Answer:

10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28 = 180/9 = 20

mean: 20

3 4/9 as a improper fraction

Answers

First, you do the denominator times he whole number

9 x 3 = 27

Second, you add the total you got to the numerator

27 + 4 = 31

Third, Solve!

31/9 will be your answer

The improper fraction of $3(4)/(9)$ is 31/9

The given expression is,

$3(4)/(9)$

We have to write it into improper fractions,

Since we know that,

An improper fraction, such as 6/5 and 12/5, is one in which the numerator is higher than or bigger than the denominator. Compared to other types of fractions like mixed fractions, improper fractions are simpler to solve using addition and subtraction.

Now to convert it into improper fraction

Multiply 3 with 9 then add it with 4 which gives the numerator,

Therefore,

$3(4)/(9) = ((27 + 4 ))/(9)$

= 31/9

Hence,

$3(4)/(9)$ = 31/9

Find the measure of angles 1–12 in the complex figure. Explain how you found each angle measure.•line a || line b
•line c || line d
•segment EG || line e

Answers

I'll start with the triangle figure.
Interior angles of a triangle is equal to 180°. The given triangle is an Isosceles triangle. It has 2 equal sides and 2 equal angles.

#7 is 69° because its vertical angle is 69°. Vertical angles are equal.
#8 is 111°. As I said, isosceles triangle has 2 equal angles. The angle that is beside #8 is 69°, equal to #7. So, 180° - 69° = 111°
Interior angles are already given except for #4. So, 180° - 69° - 69° = 42°
#3 is computed by 180° - 42° - 69° = 69°

#9 = 116° ; alternate interior angles are equal.
#10 = 180° - 116° = 64°

The last triangle looks like an equilateral triangle. It means that its sides and angles are equal.

360° / 6 = 60°
#1, #2, #5, and #6 = 60° each
#11 = 60° - equilateral triangle, all interior angles are equal.
#12 = 30°; 180° - 90° - 60° = 30°

Study the following statement:“Two intersecting lines cannot beperpendicular to the same line”. Check whether it is an equivalent version to
the Euclid’s fifth postulate.

Answers

Euclid's fifth postulate states that 'given any two lines and a transversal, if the angles on the same side of the transversal are less than 180 degrees they will meet on that side of the transversal'. The statement given here is that two intersecting lines cannot be perpendicular to the same line, i.e., parallel. This statement is stating that the co-interior angles of intersecting lines cannot be 90 degrees in measure, and it is almost equivalent to Euclid postulate 5.

What is the difference between an irrational number and an integer? (PLZ HELP ME ANSWER ASAP!!!! All help is appreciated! :D)

Answers

So, first off it would help if you could define the terms irrational number and integer. Well, an irrational number is basically any real number that can't be expressed as a ratio of integers. They also cannot be represented by terminating or continuing decimals. And an integer is pretty much any number that cannot be written as a fraction or decimal, such as -2, 13, 257. It is not 2 and 1/2, or 4.75. Those would not be integers. Do you think you can figure out the difference?
