Statistics. <span>Statistics is a branch of mathematics which is the scientific study of mathematical values pertaining to qualitative descriptions and transcribe them into quantifying values such as the descriptive statistics and infuses these quantities in the field of inferential statistics. In these two categories involve probabilities, distribution and deviations which are mainly compositions of the descriptive statistics. Inferential statistics will involve comparison and variation of the given values. Methods are t-test, analysis of variance, and two-way analysis of variance and other methods. </span>

Answer:

127.5

Step-by-step explanation:

First, we need to find the value of x

since the two angles are connected to a straight line, their sum will be 180 (degrees)

$(2x+7)+(6x-9)=180^{o}$

add the angles together

$\therefore 8x-2=180$

add 2 to both sides

$\therefore 8x=182$

divide out by 8

$\therefore x = 22.75$

now we must determine which angle has the greater value (not visually)

$angle A = 2x+7$

$\therefore \angle{A} = 2(22.75)+7$

$\therefore \angle{A} = 45.5+7$

$\therefore \angle{A} = 52.5$

$angle B = 6x-9$

$\therefore \angle{B} = 6(22.75)-9$

$\therefore \angle{B} = 136.5-9$

$\therefore \angle{B} = 127.5$

$\angle{B}>\angle{A}\ \because\ 127.5>52.5$

so the answer would be 127.5

What is the slope of the line passing through the points (2, 5) and (-1, -4)? show your work

Sati [7]

Answer:

We can solve this question using the slope equation which is y2-y1/x2-x1

If you use that formula and sub in the coordinates

-4 - 5 / -1-2

-9/-3

= 3

The slope should be 3/1
