Question 3 12 points Solve each system State whether it is

A survey is done in London and people are questioned in 6 out of 32 neighborhoods Systematic Stratified Cluster Simple Random

You may need to use the appropriate technology to answer this question Develop the analysis of variance computations for the following completely randomized design At a 0 05 is there a significant difference between the treatment means A 136 119 113 107 130 114 130 95 xj 2 s 186 29 118 Treatment B 108 113 125 104 106 110 98 113 105 88 107 C 91 82 86 101 88 116 111 119 99 97 99 95 78 164 89

nd the solution set of each linear system Identify inconsistent systems and dependent equation x 3y z 20 x 4y z 18 x 3y 4z 19

Reduce the matrix to reduced row echelon form A 1 0 1 1 0

We can find the remainder for the quotient using either substitution or synthetic division as discussed in class Using either method explain whether or not we can conclude that x 5 is a factor of the polynomial f x x 17 15 Show your work process to find the remainder Your answer must include what that remainder value is and if it indicates x 5 is a factor or not

Find the slope of each line 1

Graph g x 4 cosa Use 3 14 for T Use the sine tool to graph the function Graph the function by plotting two points The first point must be on the midline and closest t the origin The second point must be a maximum or minimum value on the graph closest to the first point Sine 6 28 Move 4 71 3 14 1 57 3 g x 2 1 0 1 Undo 2 1 57 Redo 3 14 x Reset 4 71 6 28

If A B are symmetric matrices and AB BA then AB is also sym Select one True O False

1 If A 0 0 0 Select one O True 1 1 1 1 0 1 1 then Nullity A 0 1

If A B are symmetric matrices and AB BA then AB is also symmetri Select one O True 0 False
