If you would like to solve <span>(8r^6s^3 – 9r^5s^4 + 3r^4s^5) – (2r^4s^5 – 5r^3s^6 – 4r^5s^4), you can do this using the following steps:
</span>(8r^6s^3 – 9r^5s^4 + 3r^4s^5) – (2r^4s^5 – 5r^3s^6 – 4r^5s^4) = 8r^6s^3 – 9r^5s^4 + 3r^4s^5 – 2r^4s^5 + 5r^3s^6 + 4r^5s^4 = 8r^6s^3 – 5r^5s^4 + r^4s^5<span> + 5r^3s^6
</span>
The correct result would be 8r^6s^3 – 5r^5s^4 + r^4s^5<span> + 5r^3s^6.</span>

Answer: 0.0475
Step-by-step explanation:
Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.
Where , Population mean : 
Standard deviation : 
To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.
∵ 
Then , for x= 3,000,000

Then , the probability that the firm’s sales will exceed $3 million is given by :-

Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
Answer:
f = 3
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
Using (6,8) and (f,-7) then
m = (-7 - 8)/(f - 6) = 5
- 15 = 5(f - 6)
-15 = 5f - 30
5f = 30 - 15
5f = 15
f = 3
