Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
We know: the sum of the angles in any quadrilateral is 360°.
Therefore we have the equation:
108 + 108 + 2x + 2x = 360 <em>cobine like terms</em>
(108 + 108) + (2x + 2x) = 360
216 + 4x = 360 <em>subtract 216 from both sides</em>
4x = 144 <em>divide both sides by 4</em>
x = 36

Answer:
The answer is 88%
Step-by-step explanation:
To find a percentage, just divide the top number by the bottom. 22 divided by 25 is 0.88 which means 22 out of 25 is 88%.
Another way to do it is to multiply both 22 and 25 by 4. The denominator will now equal 100 so now the top number will be the percentage. 22*4 is also 88.
Hope this helped.
Answer:
(4) Hours studying compared to test score
Step-by-step explanation:
Bivariate means two (bi-) variables. That means we must test for two variables for the data. Let’s analyze each of the choices.
(1) Shoe sizes of a tennis team: We are only measuring one variable: shoe sizes, so let’s eliminate this.
(2) Goals scored in soccer game: We are only measuring one variable: goals scored, so let’s eliminate this.
(3) Calories consumed in one day: We are only measuring one variable: calories consumed, so let’s eliminate this.
(4) Hours studying compared to test score: Here, we must measure the hours studying and the test score for the data, which are two variables. Therefore, this is our answer.
I hope this helps! :)
