CC2 – Chapter 5 TEST Review Name:____________________________ March 29, 2017 Period:_______________________ 1. Adding and subtracting whole number integers. In some cases,
multiplying integers first.
5(15) + (- 35)
To solve:
1. Try to get each term into simplest form. Remember,
terms are separated by addition or subtraction. It
might help to circle the terms.
2. SO, first of all, we need to work with this term:
5(15) = _______
3. Then, we can add that term and the second term:
1st term _____ + ( -35) = _______
2. Integer diamond problems
5-64. Copy and complete each of the Diamond Problems
below. 3. Using a spinner to figure out probabilities
•
5-110. The spinner below is spun twice. Make a table and
calculate the probability of each of the following outcomes.
a. Getting black twice.
b. Getting green twice.
4. Compound probability
5-69. Represent all of the possible outcomes using a list, probability table, or
probability tree. Then find the indicated probability in each situation below.
a.
You flip a coin three times in a row and get heads exactly twice.
b.
You spin the two spinners at right and exactly one spinner lands on 4.
5.Tree diagrams
5-68. In a power outage, Rona has to reach into her closet in the dark to get
dressed. She is going to find one shirt and one pair of pants. She has three
different pairs of pants hanging there: one black, one brown, and one
plaid. She also has two different shirts: one white and one polka dot.
a.
Draw a probability tree to organize the different outfit combinations
Rona might choose.
b. What is the probability that she will wear both a polka dot shirt and plaid
pants?
c. What is the probability that she will not wear the black pants?
6. Simple Probability
•
1-51. GO FISH
•
Mike wants to win a giant stuffed animal at the carnival. He decided to
play the “Go Fish” game, which has three prizes: a giant stuffed animal, a
smaller stuffed animal, and a plastic kazoo.
•
The game is set up with a tank containing 1 green fish, 3 blue fish, and 6
yellow fish. To play, Mike must go fishing. The game is set up so that every
time a player goes fishing, he or she will catch a fish.
•
To win the giant stuffed animal, Mike needs to catch a green fish.
a. If all of the fish in the tank are green, how would you describe the
probability of Mike’s winning a giant stuffed animal?
b. The way the tank is set up (with 1 green, 3 blue, and 6 yellow fish), what
are the chances that Mike will catch a black fish?
c. Given the information in the problem, what percent of the time would
you expect Mike to catch a green fish and win the giant stuffed animal?
7. Order of operations
5-33. Evaluate the following expressions using the Order of Operations.
1. 3(8 − 4) + 42 − (2 + 3)
2. 7 · 4 − 3 · 8 + 22 – 6
3. 7 − (−3) + (−4 + 3)
4. −6 −4(3 · 2) + 52
8. Calculating the intervals in a parts to whole linear diagram
(percentage/amount number line) (as in the beginning of Ch. 5)
•
5-9. Find the missing values on the diagram below. Assume that each
line is evenly divided.
•
9. Word problems using the 5D Model
•
5-118. Ms. Pacheco, Mr. Edwards, and Mr. Richards are three math
teachers at Turner Middle School. Ms. Pacheco is three years older than Mr.
Richards. Mr. Edwards is twice as old as Mr. Richards. The sum of Mr.
Richards’ age and Mr. Edwards’ age is 81. How old is each person?
•
5-119. Ramon was studying pond life in Doyle Park. In two hours, he
counted four more frogs than turtles. The number of crayfish he counted was
three more than twice the number of turtles. In total, he counted 54 turtles and
crayfish. How many frogs were there?
•
5-120. Dawn is trying to find the dimensions of a parallelogram. She
knows that the base is one unit less than twice the height of the shape. The area
is 91 square units. How long are the base and height?
10. “Find the number” game
a.
Ryan is thinking of a number. When he multiplies this number by 6 and
then subtracts 15 from the answer, he ends up with his original number. What
number is Ryan thinking of?
