2x + 7 = 21
first you subtract the 7 from the 7 and 21 which will leave you with 2x=14
then see what multiples with 2 to get 14 which is 7!
It would be 13,500 and 84,900 because if the number behind the first one is five or higher u round up if not you round down
Answer:
What are the options I will figure it out
Step-by-step explanation:
Based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
<h3>What are Scatterplots?</h3>
- Scatter plot is a graphical tool that shows a trend between a dependent and independent variable.
- The trend line can be used to make predictions.
Given the scatter plot as shown above, at 160 cm arm length spam, if we trace it up to the trend line, the corresponding predicted foot length lies between 21 - 23 cm.
Therefore, based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
