Raphael is traveling in a straight line at a constant speed from point A to point B. His distance from point B in miles is -20t+
Rudik [331]

Answer:

Speed  = 20 mi/h

Explanation:

There are two points A and B

Distance between both the points are define with function -20t + 45 miles

where t represent the number of hours of travelling.

Now firstly we find the initial position. At starting time is 0, so we put t=0 in given function of t.

At t=0;

d₀ = -20(0) + 45 = 0 + 45 = 45 miles

Now we find the distance travell after starting first hour.

Than we put t = 1 in the given function

At t = 1;

d₁ = -20(1) + 45 = -20 + 45 = 25 miles

Difference between d₁ & d₀ is

45 - 25 = 20 miles

We see that in one hour, total distace is covered 20 miles

Now we use time, speed, distance relation

Speed = distance/time

Speed= \frac{20}{1}

Speed = 20 miles/hour

That's the final answer.

I hope it will help you.

Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all
Mamont248 [21]

Using the concept of probability, the probability of not landing on <em>yellow or red at all</em> is 1/4.

<u>Creating</u><u> </u><u>a</u><u> </u><u>square</u><u> </u><u>model</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>two</u><u> </u><u>spins</u><u> </u><u>:</u>

  • Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

  • <em>Sample</em><em> </em><em>space</em><em> </em><em>=</em><em> </em><em>4²</em><em> </em><em>=</em><em> </em><em>16</em>

<u>Combinations</u><u> </u><u>without</u><u> </u><u>red</u><u> </u><u>and</u><u> </u><u>yellow</u><u> </u><u>:</u>

  • {BB, BG, GB, GG}
  • <em>Number</em><em> </em><em>of</em><em> </em><em>selections</em><em> </em><em>without</em><em> </em><em>red</em><em> </em><em>or</em><em> </em><em>yellow</em><em> </em><em>=</em><em> </em><em>4</em><em> </em>

<u>Recall</u> :

  • <em>Probability</em><em> </em><em>=</em><em> </em><em>required</em><em> </em><em>outcome</em><em> </em><em>/</em><em> </em><em>Total possible</em><em> </em><em>outcomes</em><em> </em>

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on <em>yellow</em><em> </em><em>or</em><em> </em><em>red</em><em> </em><em>at</em><em> </em><em>all</em><em> </em>is 1/4.
