PROJECT MATH - ANGLE OF ELEVATION AND DEPRESSION - Guys can anyone help me of this project

- I have to write a story about the picture
- Then questions
- Traingles

That’s all i would be thankful if someone helped me Due is tmrw and i really need help with it !!!

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

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?

Math i have no idea how to do a and b
