Afarmer is testing the effects of four different fertilizers on the yields of a certain variety of tomato plants. the four fertilizers are applied to each of five different tomato plants, and the numbers of tomatoes produced by each plant are recorded. fertilizer a fertilizer b fertilizer c fertilizer d 33 26 31 29 29 22 36 34 37 16 42 30 39 17 34 31 35 20 30 34 a. conduct an anova to test the null hypothesis that the means of each fertilizer are all equal. b. if the means of the three fertilizers are not all equal, conduct a t-test to test each pair of means (note: you will need to know if the variances of the samples are equal)

Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of triangle abc is 180

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
