Answer:

slope = - \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ )/ (x₂ - x₁ )

with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (- 4, 10)

m = \frac{10-8}{-4-0} = \frac{2}{-4} = - \frac{1}{2}

Answer:

m=-1/2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

You subtract 10-8 (Y2-Y1) over -4-0 (X2-X1). Then you simplify.

The collection of all possible outcomes of a random phenomenon is called A. the sample space. B. the distribution. C. the probab
Hoochie [10]

Answer:

Option A is correct.

Sample space is the collection of all possible outcomes of a random phenomenon.

Step-by-step explanation:

- Sample Space

The sample space of a phenomenon is the set of all possible outcomes for that phenomenon.

- Distribution

The distribution of a statistical data set is defined as a listing or function showing all the possible values (or intervals) of the data and how often they occur.

- Probability

Probability describes how likely something is to happen. Probability values are usually between 0 and 1; with 0 denoting impossibility and 1 denoting total certainty.

- Census

Census is an official count or survey of a population

F(x) = -2x + 5<br> f ( ) = 13
scZoUnD [109]

Answer:

Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.

Step-by-step explanation:

so, if f (x) equals 13, you replace the x in the equation to 13.

f(x)=-2x+5

f(x)=-2(13)+5

f(x)=26+5

f(x)=31

I believe 41 would be your answer. Hope this is right and it helped!

Choose the equation of the horizontal line that passes through the part point (1,-5)
vladimir2022 [97]
We know is a horizontal line, so, if it passes through 1,-5, it also passes through "whatever", -5, like 20, -5 or 1000000, -5, or -100000000, -5 and so on.

so, let's pick another point say -7, -5, check the picture below, and let's check about the equation that runs through it,

\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1&&x_2&&y_2\\&#10;%  (a,b)&#10;&&(~ 1 &,& -5~) &#10;%  (c,d)&#10;&&(~ -7 &,& -5~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-5-(-5)}{-7-1}&#10;\\\\\\&#10;\cfrac{-5+5}{-7-1}\implies \cfrac{0}{-8}\implies 0&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-5)=0(x-1)&#10;\\\\\\&#10;y+5=0\implies y=-5
