On this question I will be grading your work, not your answer.  At the end of this Graded Practice you will scan all your work into a single document and upload it into the last question. SHOW ALL WORK as indicated in the Video Lesson. Find the standard deviation of the following grouped frequency table: Group Frequency 6 – 14 9 14 – 22 12 22 – 30 5 30 – 38 3 38 – 46 2 46 – 54 1   Type GRADE MY WORK is this box:  The standard deviation is   (Round to 3 decimal places as needed) NOTE:  You will lose points if you do not show all work and calculations on your paper (as demonstrated in the video lesson).  

Grecia is evaluating the data that she collected of all of the ages of the students in her Introduction to Western Civilization lecture. She finds that the mean of the ages is 19. This means which of the​ following?

The time it takes Patty to ride her bike to school is normally distributed with a mean of 17 minutes and a standard deviation of 4 minutes. What is the z-score corresponding to a time of 22 minutes?

On your graph paper, NEATLY show ALL WORK solving the following system of linear inequalities.   Show ALL WORK: Find  x-intercept of each line (if it exists).   Find  y-intercept of each line (if it exists) Draw an accurate graph on your graph paper.  Shade the solution (feasible) region Label the corner points on the graph. Fill in the blanks below. On this question I will be grading your work on your graph paper.  At the end of this Graded Practice you will scan all your work into a single document and upload it into the last question. a.  Type SEE WORK in this box:  b.  The solution region is . c.  List all corner points.  Enter ordered pairs. Enter fractions in a/b form as needed.  If there are more than one, separate pairs with a comma.  NO SPACES.    

North Star Sail Company manufactures regular and competition sails.  Each regular sail takes 1 labor-hour to cut and 3 labor-hours to sew. Each competition sail takes 2 labor-hours to cut and 4 labor-hours to sew. Due to budget constraints, the hours in the cutting department cannot exceed 140 and the hours in the sewing department cannot exceed 360. If x is the number of regular sails and y is the number of competition sails the company manufacturers, write a system of linear inequalities modeling this problem.  Be sure to include appropriate restrictions on x and y.  Graph the set of feasible solutions. On this question I will be grading your work, not your answer.  On your paper, complete the following:  On your paper, write a system of linear inequalities that model the above problem.  Be sure to include any restrictions (nonnegative or otherwise) on x and y  Graph the system on your paper AND shade the solution (feasible) region.  Label the corner points on the graph. At the end of the exam you will scan all your work into a single document and upload it into the last question. a.  List all the corner points of the feasible region:  Enter ordered pairs.  Enter fractions in a/b form as needed.  If there are more than one, separate pairs with a comma.  NO SPACES. b.  Enter SEE WORK in this box:
