<h3>Answer:</h3>

2x = 60

3x = 90

x = 30

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

All triangles have 3 angles that add up to 180 degrees. We can use the information to create an equation.

Finding x

First, add all of the angles together and set them equal to 180

  • 2x+3x+x=180

Next, combine like terms

  • 6x=180

Finally, divide both sides by 6

  • x=30

Solve For Missing Angles

Now that we have x, we can solve from each of the missing angles. Do this by plugging in 30 for the x-values.

2x

  • 2(30)=60

3x

  • 3(30)=90

x

  • 30 = 30

We can check our answers by adding all of these together. Because 60+90+30 equals 180, these answers must be correct.

Answer:

x = 30°

The angles:

  • 2x° = 60°
  • 3x° = 90°
  • x° = 30°

Step-by-step explanation:

Hello!

The sum of all the angles in a triangle is 180°. So we can set up an equation for this question.

Solve the equation:

  • 2x° + 3x° + x° = 180°
  • 6x° = 180°
  • x° = 30°

We can replace 30° for all the angles.

The measures are:

  • 2(30°) = 60°
  • 3(30°) = 90°
  • 1(30°) = 30°

How do you solve 0.8=6-2.5x
photoshop1234 [79]
X=2.08

To solve you need to first get x by itself. To do that you want to subtract 6 from both sides (get 6 away from x and put on other side) which will leave you with -5.2=-2.5x next isolate x by dividing -2.5 on both sides to then get 2.08=x

Two consecutive odd integers are such that one-third the smaller is greater than one-seventh of the larger one by 6. Find the nu
vaieri [72.5K]

Answer:

the number is 33 and 35 respectively

Step-by-step explanation:

The computation is shown below:

Let us assume X and X + 2 are the two consecutive odd integers

Now the equation is

(X ÷ 3) = ((X + 2) ÷ 7) + 6

(X ÷ 3) = (X + 2 + 6 × 7) ÷ 7

(X ÷ 3) = (X + 2 + 42) ÷ 7

(X ÷ 3) =  (X + 44) ÷ 7

Now do the cross multiplication

7X  = 3(X + 44)

7X = 3X + 132

4X = 132

X = 33

And, X + 2 = 33 + 2 = 35

hence, the number is 33 and 35 respectively

in order to use a chi-square test for goodness of fit the data must satisfy a multinomial setting. one condition for a multinomi
Hitman42 [59]

The multinomial setting goodness of fit test allows to check whether the distribution of a sample corresponding to a qualitative variable (or discrete quantitative variable) is consistent with the expected results.

The Chi-square goodness of fit test is a statistical hypothesis test used to determine whether a variable is likely to come from a specified distribution or not. It is often used to check whether the sample data is representative of the full population or is it biased.

The degrees of freedom for the chi-square goodness of fit is  calculated by using the following formula: df = (r-1)(c-1) where r is the number of rows and c is the number of columns. The following conditions are the conditions required: The sampling method should be simple random sampling. The variable being observed is categorical. The expected value of the number of sample observations for each variable is at least 5.

Therefore, The multinomial setting goodness of fit test allows to check whether the distribution of a sample corresponding to a qualitative variable (or discrete quantitative variable) is consistent with the expected results.
