Parallelogram HJKL is graphed on a coordinate grid with vertices at H(2,2), J(5, 2), K(-3,-3), and L(4,-3).Parallelogram HJKL is dilated by a scale factor of t with the origin as the center of dilation to create parallelogram h prime, j prime, k prime. l prime. Which ordered pair represents the coordinates of the vertex j prime?

Two lines parallel to the same plane are parallel to eachother

Using the side-splitter theorem, daniel wrote a proportion for the segment formed by luke segment de. what is ec?

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$⁢79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$⁢19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$⁢75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$⁢21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let μ1μ1 be the true mean repair cost for type i ovens and μ2μ2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
