You have to use the formule: y2-y1/x2-x1
-2-(-2)/4-(-3)=0/7
Answer:
1/2 is the fraction and 50% is the percentage

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.
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
Answer:
a. Decay
b. 0.5
c. 4
Explanation:
If we have a function of the form
![y=ab^x](https://tex.z-dn.net/?f=y%3Dab%5Ex)
then
a = intital amount
b = growth / decay rate factor
x = time interval
If b > 1; then the equation is modelling growth. If b < 0, then the equation is modelling decay.
Now in our case, we have
![y=4(\frac{1}{2})^x](https://tex.z-dn.net/?f=y%3D4%28%5Cfrac%7B1%7D%7B2%7D%29%5Ex)
Here we see that
inital amount = a = 4
b = 1/ 2 < 0, meaning the function is modeling decay
decay factor = b = 1/2
Therefore, the answers are
a. Decay
b. 0.5
c. 4
