1st and 3rd and 4th are yes
2nd and 5th are totally incorrect
The answer is 2, y=-3x-5
Slope-intercept form is y=mx+b, where m is slope and b is the y-intercept.
So if m=-3 and b=-5, the equation is y = -3x -5
Given:
Total number of cubes = 40
Red cubes = 18
Blue cubes = 13
Yellow cubes = 9
Aysha adds some more red cubes into the bag.
The probability now that she will take a red cube is 0.5.
To find:
The probability that she will take a yellow cube.
Solution:
Let Aysha adds x red cubes into the bag. Then,
Number of total cubes = 40+x
Number of red cubes = 18+x
Probability of getting a red cube is:

The probability now that she will take a red cube is 0.5. So,





Divide both sides by 0.5.


It means Aysha adds 4 more red cubes into the bag.
Now, the total number of cubes int he bag is:

Probability of getting a yellow cube is:


Therefore, the required probability is
.
I guess maybe 5/35 because there are only 5 chances that you could get one of the 5 in the 35 people
