Answer:
The probability of the event of identifying both the defective bulb in the second attempt is
.
Step-by-step explanation:
The number of good light bulbs is 5 and the number of defective bulbs is 2.
It is provided that when a defective bulb is found in the inspection it is disposed.
If a defective bulb is found in the first trial the probability of his event is
.
Now the remaining number of bulbs is 6.
If a defective bulb is found in the second trial the probability of his event is
.
So the probability of identifying both the defective bulb in the second attempt is:
P (Selecting a defective bulb in 1st attempt) × P (Selecting a defective bulb in 2nd attempt) =
Thus, the probability of the event of identifying both the defective bulb in the second attempt is
.
Answer:
Interchange the variables and solve for y
inverse = y = ±√x+12
Step-by-step explanation:
y=x^2-12 becomes x=y^2-12
x+12=y^2
±√x+12=y
Answer:
−7.6n+9.7
Step-by-step explanation:
First, lets put the equation
≈3.7 - 4.6n - 3n + 6
Add light terms
−7.6n + 9.7
Now were done
Choice C, x-2y=4, Subsitute 0 for y and see what x is. Do the same for the y-intercept
Tony's dorm is 7.5 miles far from the library.
Step-by-step explanation:
Given points are;
(4,0) and (12,6)

Using point distance formula;
Distance = 

One unit represents 0.75 miles, therefore,
10 units = 0.75*10 = 7.5 miles
Tony's dorm is 7.5 miles far from the library.
