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):

What is the measure of an angle that is it’s own complement ?
ValentinkaMS [17]

A complement is angle that can be added to another to equal 90 degrees.

So two times the same number would equal 90.

90 / 2 = 45

The angle that is its own complement is 45 degrees.

What is the value of x in the right triangle below? Show your work and round your answer to the nearest hundredth. ​
navik [9.2K]

The length of the hypothenuse or the value of x is equal to 19.53

Data;

  • hypothenuse = x
  • adjacent = 11.2
  • opposite = 16
<h3>Pythagoras's Theorem</h3>

To solve this problem, we have to use Pythagoras's theorem which is used to find the missing side in a right angle triangle if we have at least two sides.

The formula for this is

x^2 = y^2 + z^2\\

Let's substitute the values and solve for the missing side

x^2 = 16^2 + 11.2^2 \\x^2 = 256 + 125.44\\x^2 = 381.44\\x = \sqrt{381.44} \\x = 19.53

The length of the hypothenuse or the value of x is equal to 19.53

If you shift the linear parent function, f(x) = x, down 6 units, what is the
Tpy6a [65]

Answer:

f(x) = x - 6

Step-by-step explanation:

The original function would go through (0,0) since you shift the function down 6 units, it will go through (0,-6)

so, the equation of the line would be f(x) = x - 6
