Answer: y = 70° x = 110°

Steps:
X and the angle 110° correspond to eachother so x must equal 110°

110 + 110 + y(2) = 360
220 + y(2) = 360
y(2) = 360 - 220
y(2) = 140
y = 70

Check:
70 + 70 + 110 + 110 = 360
140 + 220 = 360
360 = 360 ✅

I would appreciate brainliest if this was correct and helpful! :)

Answer:

X= 110

Y=70

X and the degree given are the same and you find Y by subtracting 110 from 180

Determine which of the following terms are not considered to be like terms with the expression -6s ( the two is squared like on
Iteru [2.4K]

Answer:

s^2t^2

4(s\cdot t)

-6(s^2+t)

Step-by-step explanation:

We want to select all the terms that are not considered to be like terms with -6s^2t.

The terms that are like terms with -6s^2t must have s^2t.

It doesn't matter the coefficient.

So we can easily see that all the following are not like terms with -6s^2t:

s^2t^2

4(s\cdot t)

-6(s^2+t)

Write a linear function f with the values f (0) =4 and f(3)=-8
Darya [45]

Answer:

Answer:

f(x) = - 4x + 4

Step-by-step explanation:

Step-by-step explanation:

A linear function has the form

f(x) = ax + b, thus

f(0) = a(0) + b = 4, that is

0 + b = 4 , hence b = 4

f(3) = 3a + b = - 8 ← substitute b = 4

3a + 4 = - 8 ( subtract 4 from both sides )

3a = - 12 ( divide both sides by 3 )

a = - 4, thus

f(x) = - 4x + 4

A math test is worth 100 points and has 38 problems. each problem is worth either 5 points or 2 points. how many problems of eac
blondinia [14]
Hey there,
There are 2 ways
1st way:
Since there are 8 5 point problems, 38 - 8 = 30, will give you the 2 point problems.

2nd way: 
8 x 5 = 40
100 - 40 = 60
60 / 2 = 30
Thus there are 30, 2 point problems.

Hope this helps :))

Which of the following operations is true regarding relative frequency distributions? Multiple choice question. No two classes c
pshichka [43]

Answer:

The relative frequency is found by dividing the class frequencies by the total number of observations

Step-by-step explanation:

Relative frequency measures how often a value appears relative to the sum of the total values.

An example of how relative frequency is calculated

Here are the scores and frequency of students in a maths test

Scores (classes)              Frequency                Relative frequency

0 - 20                                10                               10 / 50 = 0.2

21 - 40                               15                               15 / 50 = 0.3

41 - 60                               10                               10 / 50 = 0.2

61 - 80                                5                                 5 / 50  = 0.1

81 - 100                             <u> 10</u>                                10 / 50 = <u>0.2</u>

                                          50                                               1

From the above example, it can be seen that :

  1. two or more classes  can have the same relative frequency
  2. The relative frequency is found by dividing the class frequencies by the total number of observations.
  3. The sum of the relative frequencies must be equal to one
  4. The sum of the frequencies and not the relative frequencies is equal to the number of observations.
