Figure A below is translated 4 units left and 1 unit down and then reflected over the y-axis. On a coordinate plane, triangle A has points (5, negative 2), (5, negative 3), (2, negative 4). Triangle B has points (negative 1, negative 3), (negative 1, negative 4), (2, negative 5). Which best explains whether figure B is the image of figure A under the specified transformations? Figure B is not the image of figure A because the triangles are not congruent. Figure B is not the image of figure A because the transformations were performed in an incorrect order. There is not enough information to determine whether figure B is the image of figure A after the transformations. Figure B is the image of figure A. The transformations were performed correctly.

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.

What is the value of x when x + 7 = 21?

The accompanying normal probability plot was constructed from a sample of 30 readings on tension for mesh screens behind the surface of video display tubes used in computer monitors. does it appear plausible that the tension distribution is normal? the given probability is has a significant downward curve, so it is plausible that the tension distribution is normal. the given probability is has a significant downward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is plausible that the tension distribution is normal. the given probability is has a significant upward curve, so it is not plausible that the tension distribution is normal. the given probability is quite linear, so it is not plausible that the tension distribution is normal.
