Answer:

It is the || button.

Step-by-step explanation:

|| means that 2 lines are parallel, which is proven to be true in the figure because both lines are perpendicular to line D

Answer:

they are parallel, aka "A"

Step-by-step explanation:

the lines (NOT line segments) never ever cross or meet eachother so they must be paralell

The first step in graphing data in a scatter plot is which of the following?
faust18 [17]

The slope of a line with points (8, 42) and (3, 25) is -17/5

<h3>The first step in graphing data in a scatter plot</h3>

To graph a scatter plot, we simply determine the axis to plot each of the corresponding data

The axes are simply x and y axes

Hence, the first step in graphing data in a scatter plot is (d) Determine which axis corresponds to which data.

<h3>The slope of the line</h3>

The points are given as:

(8, 42) and (3, 25)

The slope of the line is calculated as:

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

This gives

m = (25 - 42)/(3 - 8)

Evaluate

m = -17/5

Hence, the slope of a line with points (8, 42) and (3, 25) is -17/5

A person is standing in the middle of a large plaza. The person randomly takes a step either north, south, east or west and then
ivolga24 [154]

Answer:

distance between 2 and 3 away from the origin (0,0)

Step-by-step explanation:

I tried this as a simulation.

Let y = a random number.

for x := 1 to 1000 do begin

for y := 1 to 5 do begin

a := random(4)+1;

if a := 1 then v:= v +1           That is he's going north

if a:=  2 then v:=v - 1           That is south

if a:= 3 then h := h + 1         west

if a :=4 then h :h - 1             east

end;

end;

I am running a thousand simulations  

This not my actual coding. I'm made it so that it runs 5000 times

You don't have to keep score of the distance until the end.

Most of the time it gives me a distance of between 2 and 3. The quadrants are random The horizontal distance and vertical distance come in at 2 and 3 respectively or -2 and 3 or 2 and - 3 or -2 or -3 etc.

Setting this up as a tree would almost give you as many branches as a tree outside your window.  But you can try drawing it you like. At least one of them.

What are the chances of you going straight east on a run

Wouldn't it be 1/4 * 1/4 * 1/4 * 1/4 * 1/4 = 1/1024 = 0.000976

Now imagine the tree branch for this. There are over 1000 branches that it could take.

So five steps going east would be  -1 + -1 + -1 +-1 + - 1 = - 5 = h

Vertical = 0

Running this simulation occasionally does give 0.

he weight of male babies less than months old in the United States is normally distributed with mean pounds and standard deviati
Degger [83]

Answer:

Step-by-step explanation:

Hello!

The variable of interest is

X: Weight of a male baby (pounds)

X~N(μ;σ²)

μ= 11.5 pounds

σ= 2.7 pounds

a) Find the 81st percentile of the baby weights.

This percentile is the value that separates the bottom 81% of the distribution from the top 19%

P(X≤x₁)= 0.81

For this you have to use the standard normal distribution. First you have to look the 81st percentile under the Z distribution and then "translate" it to a value of the variable X using the formula Z= (X- μ)/σ

P(Z≤z₁)= 0.81

z₁= 0.878

z₁= (x₁- μ)/σ

z₁*σ= x₁- μ

(z₁*σ) + μ= x₁

x₁= (z₁*σ) + μ

x₁= (2.7*0.878)+11.5

x₁= 13.8706 pounds

b) Find the 10th percentile of the baby weights.

P(X≤x₂)= 0.10

P(Z≤z₂)= 0.10

z₂= -1.282

z₂= (x₂- μ)/σ

z₂*σ= x₂- μ

(z₂*σ) + μ= x₂

x₂= (z₂*σ) + μ

x₂= (2.7*-1.282)+11.5

x₂= 8.0386 pounds

c) Find the first quartile of the baby weights.

P(X≤x₃)= 0.25

P(Z≤z₃)= 0.25

z₃= -0.674

z₃= (x₃- μ)/σ

z₃*σ= x₃- μ

(z₃*σ) + μ= x₃

x₃= (z₃*σ) + μ

x₃= (2.7*-0.674)+11.5

x₃= 9.6802 pounds

I hope this helps!

Please answer correctly! I will give brainliest to whoever answers CORRECTLY PLs check my profile for other chances to recieve b
densk [106]

Answer:

A

Step-by-step explanation:

We know that negative numbers are smaller than positive numbers, so let's compare the 2 negative numbers. Unlike positive numbers, the more negative it has, the smaller it is. So we know the smallest is -20. Without looking at the other numbers (even though I did just in case) we know that this is correct. They say least to greatest, so -20 should be first. A is the only one that starts with -20.
