Answer:
6x^2 - 10x - 24
Step-by-step explanation:
- Do 3x times 2x which is 6x^2
- Do 3x times - 6 which is -18x
- Do 4 times 2x which is 8x
- Do 4 times - 6 which is - 24
- You get 6x^2 - 18x + 8x - 24
- Simplyify to get the answer
80 * 5/8 will give you how many are thoroughbreds.
80 * 5/8 = 50
Now subtract this from all of the horses.
80 - 50 = 30.
There are 30 quarter horses.
OR If 5/8 of the horses are thoroughbreds, then 3/8 are quarter horses.
80 * 3/8 = 30.
Answer: We are using a line regression tool to solve the parameters asked in the problem. We can use online tools or that of Excel. According to the tool, the best fit values are
Slope0.3848 ± 0.03956
Y-intercept0.6053 ± 0.6370
X-intercept-1.573
1/Slope2.598
Step-by-step explanation: Best fit lines make sure that the standard deviation at each point is minimum from the best fit line.
