Answer:

-6.8

Step-by-step explanation:

To find the mean, you add all the numbers together, then divide that number by the amount of numbers there were, so:

-9 + -9 + -3 + -6 + -7 = -34

-34/5 = -6.8

Yoooo, if you gave me brainliest that would be pretty pog. Because as it turns out, only a small percentage of the people I answer actually give me brainliest. I'm trying to get Virtuoso by the end of the day, and you giving me brainliest would really help out. Also while you're at it leave a thanks and a 5-star rating to help boost this answer in the brainly algorithm.

what is the equation in point-slope form of the line passing through (0, 5) and (−2, 11)? (1 point) y − 5

makkiz [27]

According to the question, the line is through the points $(0,5)$ and $(-2,11)$

To calculate the slope using standard formula that is :

$m = \frac{(y(2)-y(1))}{(x(2)-x(1))} = \frac{(11-5)}{(-2-0)} =\frac{6}{-2} = -3$

Now the slope equation will be: $m(x(2)-x(1)) = (y(2)-y(1))$

$y-5 =(-3)(x-0) = y = -3(x)+5$

The slope-intercept form is: $y = -3x+5$

What is the equation of the line?

To represent the set of points in an algebraic form is known as the equation of line. The set of points represent lines in the coordinate system. The parameters can be calculated and those parameters are slope and y-intercept.

The three angles of a triangle are in the ratio 5:4:1. Find all the angles of the triangle.

solniwko [45]

Answer:

Step-by-step explanation:

let the first angle be 5x

second be 4x

and third be 1x

as we know that by adding all the sides of triangle we get 180°

therefore ,

5x+4x+1x=180°

10x=180°

hence ,

x=18°

first angle - 18*5 = 90°

second angle - 18*4=72°

third angle - 18°
