(a) Describe r shw n the diagram where there are verlapping faces. Methd # cunt the number f epsed sides: 4 units Methd # there are 6 cubes that make up the cmpsite bject. Each cube has a surface area f 6 units. There are 6 verlap faces. Surface Area = ttal (verlap) = 6 (6) = 4 units.

Evaluate using BEDMAS: (a) + = = = Chapter 4 Linear Relatins. The crdinate plane has tw number lines that intersect at a pint called the rigin. The hrizntal number line is called the -ais. The vertical number line is called the y-ais. The tw aes divide the crdinate plane int fur parts called quadrants. The lcatin f a pint n the graph is given using an rdered pair. The first number is the -crdinate and the secnd number is the y-crdinate.. (a) A (, -4) I (-, -6) (c) H (, ) (d) C (, 0) (e) E (-, ) (f) N (-6, 4)

8 Chapter 8 Circle Gemetry. The pints n a circle are all the same distance frm the center. A line segment frm the center t any pint n a circle is called a radius. A line segment with bth endpints n a circle is called a chrd. A chrd that passes thrugh the center f a circle is called a diameter. The length f a radius is half the length f a diameter.. (a) = = 6.

(c)d yu, like mst peple, bey the speed limit? - D yu bey the speed limit?. (a) Timing is an issue. After several incidents f vandalism, peple will be mre likely t supprt a curfew. Privacy is an issue. Peple mst likely d nt want ther t knw if they have had a traffic vilatin, in case they perceive them as a bad/careless driver.. (a) Ppulatin: all cell phnes prduced Census r Sample: mst likely a sample, t many cell phnes t test Ppulatin: all grade students (desn t state in a schl, district, prvince) Census r Sample: if in a schl, a census culd be dne If in a district/prvince, a sample shuld be dne 4. (a) Every n th persn is called systematic sampling. Breaking int grades and nly asking frm r a few grades is called clustered sampling. (c) Breaking peple int grups (pages n a phne bk) and then picking peple frm each grup (page) is called stratified randm sampling.
