So, we can define probability as the following ratio: Number of successful outcomes over Number of total outcomes. Suppose we define an event to be the drawing of one transistor from the lot. If we want to calculate the probability that it is defective, a "successful" event would be drawing a defective transistor. Hence there is 1 successful event. But we can choose from 500 transistors, hence there are 500 total outcomes. Thus, the ratio that defines the probability P is: p=1/500. Calculating this, yields that p=0.002 or p=2%
Answer:
inverse= 3. rational=-3/1
This is your answer
Answer:
8/5
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (4- -4)/(1 - -4)
= (4+4)/(1+4)
=8/5
By the law of cosines, the angle
satisfies
which reduces to
which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
