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;

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.

The speed of light is 3 x 10 8 meters per second (m/s). What is the speed of light in miles per year (mi/yr)

GenaCL600 [577]

Answer:

the speed of light in miles per year is 5.88 × 10^12 mi / year

Step-by-step explanation:

The computation of the speed of light in miles per year is shown below;

As we know that

1 m/sec = 1 ÷ 1609 mi/sec

3 ×10^8 m/sec = (3 × 10^8) ÷ (1609)

= (3 × 10^8 × 60 × 60 × 24 × 365) ÷ (1609)

= 5.88 × 10^12 mi / year

Hence, the speed of light in miles per year is 5.88 × 10^12 mi / year

A teacher writes an inequality x divided by 6 < -2 on the board. Vincent incorrectly solves the inequality and obtains x <

scZoUnD [109]

The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Step-by-step explanation:

Given inequality that the teacher wrote is:

$\frac{x}{6} -2$

Solving an inequality means that the variable should be isolated on left side of the inequality.

So multiplying both sides by 6

$6* \frac{2}{6} < -2 * 6\\x < -12$

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

231 m 31 cm -14 m 48cm

frozen [14]

296 cm is your answer Cody. A easier way to do this question with coming on to brainly. Is add all the positive Integers OR Numbers together and then add all the negative numbers together. Then subtract the negative numbers from the positive. Something like this.
