P(one head in one toss) = 1/2

P (2 heads) = 1/2 * 1/2 = 1/4

Nataly [62]

Start with

$\dfrac{x}{2}+\dfrac{3}{2}$

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

$x+3$

Subtract 3 from both sides:

$x$

A pencil holder contains only six blue pencils and three red pencils. If two pencils are drawn at random, what is the probabilit

erastova [34]

6 blue pencils and 3 red pencils means 9 total pencils. So the probability of pulling out ONE blue pencil would be 6/9 or about 67 percent. TWO blue pencils would be HALF of that. So 6/9 * 1/2 which is 6/18 or 1/3 or about 33 percent.

Suppose an auto racer won a 400 mile race with a time of 1:41:58. at one point the racer was 40 miles closer to the finish tha

enot [183]

400/2 = 200
200 + 20 = 220
200 - 20 = 180
Answer: He had gone 220 miles.

He was 180 miles from the finish and 220 from the start, so he was 40 miles closer to the finish than to the start.

The image of the point (-6, -2) under a translation is (-4,2). Find the coordinates of the image of the point (-3, 4) under the

QveST [7]

ANSWER

(-1, 8)

EXPLANATION

First we have to find the rule for this translation.

The image of the x-coordinate of the given point is 2 untis more than the point, so the rule for the horizontal translation is to add 2.

The image of the y-coordinate of the given point is 4 units more than the point, so the rule for the vertical translation is to add 4:

$(x,y)\rightarrow(x+2,y+4)$

Therefore, the image of point (-3, 4) under the same translation is:

$(-3,4)\rightarrow(-3+2,4+4)=(-1,8)$
