Help please
need to match with the correct graph

7. h(x) = -3x^2

8. vertex: (1,-2); axis of symmetry: x = 1
domain: all real numbers, range: y>_-2

9. The graph is a vertical stretch by a factor of 5 of the graph of f(x) = x^2.

10. 8(x) =3/5 x²

11. vertex: (2,-3); axis of symmetry: x = 2
domain: all real numbers, range y<_-3

12. The graph is a vertical shrink by a factor of 1/5of the graph of f(x) = x^2 and a reflection in the x-axis

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
