For this case, what we must do is calculate the speed of the runner.
We have then that the speed is given by:
![v =\frac{d}{t}](https://tex.z-dn.net/?f=%20v%20%3D%5Cfrac%7Bd%7D%7Bt%7D%20%20%20)
Where,
d: distance
t: time
Substituting values we have:
![v = \frac{8}{92}](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cfrac%7B8%7D%7B92%7D%20%20)
![V = 0.09 \frac{miles}{minutes}](https://tex.z-dn.net/?f=%20V%20%3D%200.09%20%5Cfrac%7Bmiles%7D%7Bminutes%7D%20%20%20)
Answer:
the runners unit rate is:
![V = 0.09 \frac{miles}{minutes}](https://tex.z-dn.net/?f=%20V%20%3D%200.09%20%5Cfrac%7Bmiles%7D%7Bminutes%7D%20%20%20)

Answer:
a. 2x + 4
Step-by-step explanation:
Four more than twice a number
Let x = unknown number
Four more than twice of x
Twice of x can be written as 2x
Four more than 2x
Four more can be written as + 4
We get 2x + 4
Answer:
(a) Minimum red blood cells 5.744 million cells per micro liter
(b) Maximum red blood cells 5.068 million cells per micro liter.
Step-by-step explanation:
Z-score formula is = ![\frac{x-u}{Standard deviation}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-u%7D%7BStandard%20deviation%7D)
Z-score = ![\frac{x-5.5}{0.4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-5.5%7D%7B0.4%7D)
The value of z-score is 0.61 so then x will be;
x = 5.744
The minimum red blood cells count that can in top is 27% of count which is 5.744 million cells per micro liter.
Z-score = ![\frac{x-5.5}{0.4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-5.5%7D%7B0.4%7D)
The value of z-score is 0.14 so then x will be;
x = 5.068
The maximum red blood cells count that can be in top is 14% of count which is 5.068 million cells per micro liter.
