A student wrote the steps down for constructing a line perpendicular to a given line through point K, a point on the given line.
1. With the point of the compass on K, conštruct arcs with the same radius on the
line, one to the right of K and the other to the left. Label these points J and L.
2. Place the point of the compass on point ), open the width of the compass past
point K, and mark an arc above the line.
3. Adjust the compass width, center it at point L, and mark an arc above the line.
4. Draw a line through K and the intersection of the arcs above the line.

In which step did the student make an error?

a. step 1
b. step 2
c. step 3
d. step 4

Please provide an explanation if you can! Thanks!!

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

Whit h equation best represents this situation the number 98 increased by an unknown number equal to 120

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?
