Answer:
Part A: impossible
Part B: Either equal or blue
Part C: 9 green and 2 blue were added
Step-by-step explanation:
Part A:
The only colors included in this problem are red, blue, and green. There is no black colored pencil, therefore, it is impossible to get one from the box.
Part B:
I'm not sure what you're asking in this question, but I will give you the two choices. If it is before the additional 11 colored pencils are added to the box, the chance of drawing a red and the chance of drawing a blue will be equal, because both of them have 11 of each color. If it is after the additional 11 colored pencils are added to the box, then the chance of drawing a blue colored pencil will be greater than the chance of drawing a red colored pencil. After the 11 colored pencils are added, there are 13 blue and 11 red. The blue is greater.
Part C:
The least number of green colored pencils added has to be 9, because the chance of drawing a green pencil is now greater than the chance of drawing a red pencil. If we add 8 more green pencils, the likelihood would be the same. Therefore, the number of green colored pencils added has to be at least 9. If we have the last 2 colored pencils be blue, then there would be 11 red, 13 blue, and 12 green. This fits all the conditions, therefore, adding 9 green colored pencils and 2 blue colored pencils is the answer.
I hope this helps and please mark me as brainliest!

Answer:
1,570,000
Step-by-step explanation:
The sum is approximately ...
1,260,000 +310,000 = 1,570,000
_____
<em>Additional comment</em>
It is a good idea to estimate the error associated with an estimate. Here, both numbers are rounded up by about 4000 each, so the estimate is around 8000 high.
Answer:
10
Step-by-step explanation:
Answer:
1. y=1/4x+2
2. y=-3/2x +1
3. y = -3/2x -2
4. y= -3x -49
5. y = -2x +8
Step-by-step explanation:
1. Use slope intercept, y=mx+b where m =1/4 and b=2. y=1/4x+2
2. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-7)=-3/2(x--4)
y-7=-3/2(x+4)
y-7=-3/2x-6
y = -3/2x -6 +7
y=-3/2x +1
3. To write the equation of a line we must have a slope and a point. To find the slope we use the slope formula and substitute (x,y) points in it as shown below:
Now that we have the slope, plug in the slope and choose one point to plug into the point slope formula. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y--5)=-3/2(x-2)
y+5=-3/2(x-2)
y+5=-3/2x + 3
y = -3/2x -2
4. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is -3 since parallel lines have the same slope.
(y--4)=-3(x-5)
y+4=-3 (x+15)
y+4=-3x -45
y= -3x -49
5. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope is -2 since perpendicular lines have the negative reciprocal slopes. So 1/2 becomes -2.
(y--6)=-2(x-7)
y+6=-2 (x-7)
y+6 = -2x + 14
y = -2x +8
