If you randomly select a beginner runner from the population have them run a 5k, what are the chances that they would finish it

between 25 and 27 minutes? That is, how many times, out of 100, would you randomly select someone that could run the 5k between 25 and 27 minutes? (Hint: use Appendix B.1 to answer this question. Start by calculating the z score for 25 and 27). Remember, you'll need to know the mean and standard deviation that you calculated for your population of runners. (Write a paragraph explaining, No Plagiarism!)
Time to complete 5k (in minutes):

yanalaym [24]

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm

Consider function f and function g.
ivolga24 [154]

The statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have two functions:

f(x) = lnx

g(x) = -5 lnx

The domain of the both functions x > 0

The function will be touch the y-axis when x reaches to the infinite.

The graphs of both functions have a vertical asymptote of x=0.

Unlike the graph of function f, the graph of function g decreases as x increases.

The graph of function g is the graph of function f vertically stretched by a factor of 5 and reflected over the x-axis.

Thus, the statement the graphs of both functions have a vertical asymptote of x=0 and statement unlike the graph of function f, the graph of function g decreases as x increases are true.
