You can use the formula for conditional probability as Puzzling did. However in this problem it is easier just to restrict yourself and enumerate the cases that are left. 

<span>There are 4 jacks. One of them is a heart. So the probability is 1/4. </span>

<span>If you want to look at what the formula for conditional probability does, it adjusts your probability by restricting the "universe". </span>

<span>P(heart and jack)/P(jack) </span>
<span>= (1/52)/(4/52) = 1/4</span>

It takes21 minutes for 5 people to paint 7walls. How many minutes does it take 3people to paint 5 walls?
scoray [572]

so 5 people work each one for 21 minutes, that means 21+21+21+21+21 minutes altogether, namely 105 minutes, it took that long for 7 walls, hmmmm how long for just one wall then? well, 105 ÷ 7, namely 15 minutes then, for just 1 wall.


now, if it takes 15 minutes of work to do one wall, what about 5 walls? well, that'd be 15*5 or 75 minutes.


so if we have 3 folks working, how much would each one work? well, 75 ÷ 3, namely 25 minutes, so each of them will work 25 minutes, namely 25+25+25 minutes, so in 25 minutes, they'll be done with 5 walls.

Please help <br><br>y≥1/3x-3​
zloy xaker [14]

Answer:

B, the one with the line and shaded the top on the right side. (The one that goes to 7 on the x axis).

Step-by-step explanation:

First I find which graph as y -intercept of -3, which is all of them.

Next, I find with graph has a slope of 1/3. (rise 1 run 3). Only B and D has a slope of 1/3 (The ones that has a less steep graph. )

Then, I use the coordinate (0,0) to see which side the graph shades. I plug it into the inequality. (0)≥1/3(0)-3​. Solve. Is 0 greater than -3. YES! so we shade the part where (0,0) is shaded which is B.
