Answer questions 1-5 based on the graph on the right. 1. Reflect the triangle ABC on the line xa-1 and then translate <2,-5>. Determine the coordinates of B". 2. What are the coordinates of C' when C is reflected on the y-axis? 3. Determine the coordinates of A' when A rotates 90° counterclockwise around the point (-2, -1). -2 -bi 4. Determine the coordinates of B' after a reflection on the line yex. Determine the coordinates of A' after a reflection on the line y=-x. Y=x (x,y) → (y,x) B (-5,5) (5,-2) V=-x (x,y) → (-Y,-x) A(-3,3)→ A (-3,-) 2-4 5. If the triangle ABC is translated <7,-5> and then rotated 180°, what is the x coordinate of C'? 4,2 -2 -2 -4,-3-1-1 Answer questions 6-7 based on the graph on the right. 6. Reflect the triangle on the line y=-x. Next, reflect the triangle ABC on the y- axis. Then rotate the shape 270° clockwise around the origin. Draw the triangle A'B'C' in the coordinate plane. 7.Turn the triangle ABC 90° clockwise, then translate it <-8,4>. Draw the triangle A'B'C' in the coordinate plane. 272 8. Consider points J (7, -3) and B (4, -9). JB goes under a translation such that J' (2, 8) and B' (-1, 2). Write the algebraic description that describes the translation. 1,7
Suppose the points scored from a population of algebra tests are normally distributed with an unknown population mean and a population standard deviation of 5.2 points. A random sample of algebra tests from the population produces a sample mean score of a 88.6 points. = What value of z should be used to calculate a confidence interval with a 95% confidence level?
