Answer:
0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Poisson distribution with an average of three errors per page
This means that 
What is the probability that a randomly selected page does not need to be retyped?
Probability of at most 3 errors, so:

In which
Then

0.6472 = 64.72% probability that a randomly selected page does not need to be retyped.

Answer:
486√3 ft² ≈ 841.8 ft²
Step-by-step explanation:
The area of a regular hexagon with side length s is ...
A = (3√3)/2s²
For the side length of 18 ft, the area is ...
A = (3√3)/2(18 ft)² = 486√3 ft² ≈ 841.8 ft²
Answer:
The equation would be y = 1/2x + 5
Step-by-step explanation:
To find this equation, we start by using point slope form, and then plugging the slope in for m and the point in at (x1, y1).
y - y1 = m(x - x1)
y - 7 = 1/2(x - 4)
And now we solve for y.
y - 7 = 1/2(x - 4)
y - 7 = 1/2x - 2
y = 1/2x + 5
