The coordinates for 0 radians would be (5,0). The coordinates for /4 radians would be [(square root of 2)/2, (square root of 2)/2]. The coordinates for /2 radians would be (0,5). 5) Consider the two points in Quadrant I on Circle B. What is the special relationship between them?
Match each with the expression or equation which best describes it. Potential Matches: 1: a + b = b + a 2: (a + b) + c = a + (b + c) 3: a(b + c) = ab + ac 4: This expression has 4 of them: 3a + b – 5 + 8d. 5: This is what the 5 in the term 5xy is called. Answers: ___: Term ___: Coefficient ___: Associative Property ___: Distributive

TOPIC 8 Chi-Square goodness-of-fit test Problem 12.1 Use a chi-square goodness-of-fit to determine whether the observed frequencies are distributed the same as the expected frequencies (α = .05) Category | fo | fe | 1 | 53 | 68 | 2 | 37 | 42 | 3 | 32 | 33 | 4 | 28 | 22 | 5 | 18 | 10 | 6 | 15 | 8 | Step 1 Ho: The observed frequencies are distributed the same as the expected frequencies Ha: The observed frequencies are not distributed the same as the expected frequencies Step 2 df = k – m – 1 Step 3 α = 0.05 x 2 0.05, 5df = 11.0705 Step 4 Reject Ho if x 2 > 11.0705 Category | fo | fe | | 1 | 53 | 68 | | 2 | 37 | 42 | | 3 | 32 | 33 | | 4 | 28 | 22 | | 5 | 18 | 10 | | 6 | 15 | 8
In this figure <1 and <8 are alternate exterior angles, as are <2 and <7. Same-side interior angles are in between the two lines that are not the transversal and are on the same side of the transversal. In this figure <3 and <5 are same-side interior angles, as are <4 and <6. Polygon interior angle sum formula S=180 (n-2) ( polygon= 180 (number of sides -2) S=180 (4-2) =
