CH27-30 Test Review

1. Determine theoretical probability of a spinner and explain how you might check it using experimental probability

2. Determine odds (chance) of winning a game, i.e Pulling a yellow ball from a bag containing 3 yellow, 2 red and 1 blue ball.

3. Given partial information, fill in the numbers of a tree diagram and determine the probability of the outcomes.

4. Given the parameters of an experiment determine the probabilities of the outcomes using and and or.

5. Fill in a contingency table given certain information about an event then use the table to compute the probability of the outcomes.

6. Use a stem-and-leaf plot to find the mean score and to make a box-and-whiskers plot. You should be able to explain each part of the graph.

Ch. 23-25 Test Review

You should be able to:
1. Determine the range of measurements given the measuring tool's limitations.
2. Convert metric measures to larger and smaller metric measures. (i.e convert km to m)
3. Determine the number of degrees in a partial circle if the ratio is known. (i.e. 15 minutes on a clock face would have how many degrees?)
4. Be able to convert between different square measurements, i.e., sq cm to sq meters
5. Determine the area of an unusual region on a Geoboard (square dot paper)
6. Determine scale factors and use them to find surface area or volume of a similar figure.
7. Given corresponding lengths of two similar objects, be able to calculate the ratio of their surface areas and their volumes (the surface area and volume factors).
8. Know how to find missing lengths (i.e. leg of right triangle, diameter & radii of a circle, perimeter, circumference), and find area of polynomials (may need to memorize formulas).

Ch.20-22 Test Review

(1)Given two 2-D figures and a dilation point you should be able to determine if they are similar and if so, find their scale factor.
(2) Given two similar 3-D figures you should be able to determine the missing dimensions for corresponding segments and angles.
(3)Given two similar 3-D objects, if you know some of their dimensions and the scale factor, you should be able to determine the surface areas.
(4)Given the volume of two 3-D objects you should be able to determine the scale factor.
(5)On a given circle, you should be able to identify: diameter, radius, chord, minor arc, major arc, inscribed angle, central angle, segment, and sector
(6)Constructions: copy angles and segments, bisect angles and segments, construct parallel and perpendicular lines, and create segments and angles that are multiples of an original (i.e. twice as big, or 1/2 larger)
(7)Be able to transpose shapes using rigid motions
