Homework #3
Find the area in terms of Pi
a. Circumference = 36 Pi cm
b. Circumference = 132 Pi cm
Find the Circumference in terms of Pi
a. Area = 36 Pi squared inches
b. Area = 225 Pi squared inches
Find the diameter, area and circumference of a circle whose radius is 16in.
UNIT 6 EXAM THURSDAY MAY 7 (Standards 7.G.3, 7.G.4, 7.G.6)
7.G.3 - Cross Sections of 3-D Figures
7.G.4 - Relationships between Pi, Circumference, Area, Radius and Diameter
Finding Circumference given Area
Step 1: Take the square root of the number with Pi to find the radius (a = pi * r squared)
Step 2: Since circumference in pi * diameter, multiply the answer to step 1 by 2
Step 3: Multiply the answer to Step 2 by Pi
Finding Area given Circumference
Step 1: Divide the number with Pi by 2 (C = pi * d and we need radius for area)
Step 2: Multiply the number found in step 1 (the radius) by itself (also known as squaring)
Step 3: Multiply the answer to Step 2 by Pi
7.G.6 - Finding area of irregular polygons, finding volume and surface area.
Volume: measurement inside figure
Surface Area: Sum of the area of each of the faces of the figure

Wednesday, May 13 - UNIT 7 Samples and Populations 7.SP.1
Homework #4
1. Describe the difference between a representative samples and a biased sample space.
2. (a) Give one example of a survey
(b) Give one example of a representative sample for that survey
(c) Give one example of a biased sample for that survey
Thursday, May 14 - UNIT 7 Samples and Populations 7.SP.1
Homework #5
1. Compare: The teachers in a school are asked to send four students from their homerooms to represent the class.
--> Ms. Rose puts the names of all the girls in a box and chooses two without looking. Then she does the same for the boys' names.
--> Mr. Burr sends the four students sitting closest to the door.
--> Mrs. Rosati puts the names of all the students in a box, mixes the names, and pulls out four names without looking.
Compare the selection methods. Do you think each one creates a random or biased sample? Which is more likely to be representative? Explain.
Friday, May 15 - UNIT 7 Samples and Populations 7.SP.2
Homework #6
Design a survey (other than one discussed today, which entails 2-3 options. Pick a random sample population, or an unbiased population, to conduct the survey on. Please make sure that there are between 10 and 15 people being sampled. Please follow the guidelines/steps/requirements listed below.
Requirements:
1. 2-3 options
2. unbiased population
3. random sample (Please make sure they are people you know! We want to stay safe during this.)
4. 10-15 people being surveyed
5. Description of population (is this survey done based off of people in your school, community, apartment building etc.?)
6. Bar Graph, Histogram, Pie Chart (Be creative and colorful)
7. Apply concepts of probability to compare your survey with a larger population such as the communities around you or in the state of New York.
PLEASE BE NEAT. YOU MAY BE CREATIVE. TRY TO USE SPACE WISELY AND MAKE A ONE-SIDED POSTER. YOU MAY DRAW OR PRINT OUT.

Homework #10
GET PROGRESS REPORT SIGNED BY PARENT/GUARDIAN AND RETURN ON TUESDAY. Missing Assignments Due Monday, June 1st. If you owe assignments, please write them on a separate sheet of paper so that you can return the signed progress report to me as your HW credit.
Tuesday, May 26 - UNIT 7 Samples and Populations 7.SP.2
Homework #11
a. Suppose you flipped a fair coin 15 times. Then, 11 of your friends did the same thing. Without actually flipping a coin, make a table to show a realistic set of data for this situation. Your table should show the percentage of heads obtained by each person doing the coin flips.
b. Organize the data in the table you constructed using a dot plot.
c. Suppose you and each of your friends decided to flip the coin 50 times each instead of 15. Explain how the dot plot above would change and sketch a predicted dot plot for the situation.
Thursday, May 28 - UNIT 7 Samples and Populations 7.SP.3
Homework #12
PART A: Find the Mean Absolute Deviation of each of the following teams:
* REMINDER (Steps for MAD)
1. Find the mean/average of football team.
2. Find the absolute value of the difference from each players height and the mean/average.
3. Find the mean/average of the absolute values. This will give you the MAD.
DO THE SAME FOR THE BASEBALL TEAM
Football Team – Height of Players in inches
60, 62, 65, 74, 71, 69, 64, 67
Baseball Team – Height of Players in inches
