Example Question #9 : How To Find The Missing Part Of A List
Five candidates are running for school board. A voter chooses two of the candidates.
Which is the greater quantity?
(a) The number of ways a voter can mark his or her ballot
(b)
It is impossible to tell from the information given
(a) and (b) are equal
(b) is greater
(a) is greater
(b) is greater
This is a choice of two out of five without regard to order - that is, the number of combinations of two out of a set of five. This is
There are ten possible ways to choose, and .
Example Question #10 : How To Find The Missing Part Of A List
Refer to the above diagram. The top row gives a sequence of figures. Which figure on the bottom row comes next?
Figure (c)
Figure (d)
Figure (b)
Figure (a)
Figure (c)
The square with the diagonal line alternates between the square on the left and the square on the right. Therefore, the next figure in the sequence will have its diagonal line in the rightmost square, eliminating Figures (b) and (d) and leaving Figures (a) and (c).
Also, the shaded square moves one position to the right from figure to figure, so in the next figure, the shaded square must be the one at the extreme right. Figure (c) matches that description.

Example Question #1 : How To Find The Points On A Coordinate Plane
Choose the best answer from the four choices given.
The point (15, 6) is on which of the following lines?
For this problem, simply plug in the values for the point (15,6) into the different equations (15 for the -value and 6 for the -value) to see which one fits.
(NO)
(YES!)
(NO)
(NO)
Example Question #2 : How To Find The Points On A Coordinate Plane
Choose the best answer from the four choices given.
What is the point of intersection for the following two lines?
At the intersection point of the two lines the - and - values for each equation will be the same. Thus, we can set the two equations as equal to each other:
point of intersection
Example Question #3 : How To Find The Points On A Coordinate Plane
Choose the best answer from the four choices given.
What is the -intercept of the line represented by the equation
In the formula , the y-intercept is represented by (because if you set to zero, you are left with ).
Thus, to find the -intercept, set the value to zero and solve for .
