Answer:

Probability = 0.6591

Step-by-step explanation:

Given

Represent P(O-Negative) with p

So:

p = 8\%

Convert to decimal

p = 0.08

Required

Determine the probability that none out of 5 is O-Negative

First, we need to determine the probability that one person is not O-Negative

Represent this with q

q = 1  - p

q = 1 - 0.08

q = 0.92

To determine the probability that none out of five, we have:

Probability = q^n

Where

n = 5

So, we have:

Probability = 0.92^5

Probability = 0.6590815232

<em></em>Probability = 0.6591<em> --- Approximated</em>

For this case we have the following function:
 f (x) = 0.01 * (2) ^ x&#10;
 By definition, the average rate of change is given by:
 AVR =  \frac{f(x2) - f(x1)}{x2 - x1}
 We evaluate the function for the given values:
 For x = 7:
 f (7) = 0.01 * (2) ^ 7&#10;&#10;f (7) = 1.28
 For x = 14:
 f (14) = 0.01 * (2) ^ {14}  f (14) = 163.84
 Then, replacing values we have:
 AVR = \frac{163.84 - 1.28}{14 - 7}
 AVR = 23.22
 Answer:
 
the average rate of change from x = 7 to x = 14 is:

Your company is hosting a benefit 5 kilometer race.
Mars2501 [29]
In this question the main part is to convert the kilometer to miles and then writing the answer to the nearest tenth of a mile. the information given in the question is that the race is for a distance of 5 kilometers.
Now we already know
1 km = 0.6214 mile
Then
5 km = ( 0.6214 * 5) miles
         = 3.107 miles
         = 3.11 miles
So the actual distance when converted to miles will be 3.11 miles. I hope this is the answer you were looking for. This is the simplest way for doing such problems and in future you can follow this method to find the answers without the need of any help.
