Error is between steps 4 and 5. It should say:
Step 4: -9x < 27
Now divide by -9
Step 5: x > -3
Note that the inequality changes direction.
When you mean multiply or divide an inequality by a negative number, the inequality changes direction.
For example:
4 < 5
Multiply by -1:
-4 > -5
Another example:
-5 < 0
5 > 0
Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.

Answer:
Option D (Yes. The model is a good fit because the residual plot does not have a random pattern).
Step-by-step explanation:
First of all, insert all the data in Microsoft Excel. Make sure that the values of X are in the ascending order. Then, make the scatter plot of the data with the line of best fit from the Insert option. The graph shows that there is a positive relation between x and y. Most of the actual values of y lie very close to the line. A very few observations are a little further from the line of best fit. Therefore, the model is a good fit because the residual plot does not have a random pattern. Option D is the correct answer!!!
