The area for this is
A= 7x9/2+3x9+9x6
= 31.5+27+54
= 112.5
Answer: The first graph is the right graph according to the given situation.
Step-by-step explanation:
Given: Becky created a graph to represent her distance away from home one afternoon.
She left home and ran to the park⇒ She started running from zero distance from the home .⇒the second and fourth graphs are wrong .
After that she met some friends and stayed at the park, then walked back home using the same route.⇒ The first one is correct because there we can see the graph is parallel to time axis for a interval but in the third one it shows that she she hasn't took rest .
Answer:
![-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988](https://tex.z-dn.net/?f=%20-0.223%20%5Cleq%20%5Cmu_%7Bsylver%7D%20-%5Cmu_%7BCountry%7D%20%5Cleq%200.988)
We can conclude that the difference between the two means are between -0.223 and 0.988.
And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.
Step-by-step explanation:
For this case we have the following interval for the difference between Silver Queen - Country Gentlemen:
![-0.223 \leq \mu_{sylver} -\mu_{Country} \leq 0.988](https://tex.z-dn.net/?f=%20-0.223%20%5Cleq%20%5Cmu_%7Bsylver%7D%20-%5Cmu_%7BCountry%7D%20%5Cleq%200.988)
We can conclude that the difference between the two means are between -0.223 and 0.988.
And for this case the confidence interval contains the value of 0 so then we have enough evidence to conclude that we don't have significant difference between the means of Silver Queen and the Country Gentlemen.
