Given
Let d represents the event that a radar detects an aircraft.
So:
Required: Determine the probability that a radar detects three before it fails to detect 1.
This event is represented as: d d d d'
And the probability is calculated as thus:
Using complement rule:
So, we have:
All you have to do is plug in and multiply.
32i+30j?
I think thats what it is :/
Answer:
in the point slop form y=2x+8
the slope is 2
the y intercept is 8
The range is the difference between her highest grade and her lowest grade.
