Answer:
The answer is "(0.461 , 7.206)"
Step-by-step explanation:
In the given question some information is missing, that is data. so, the correct answer to this question can be defined as follows:
UnLogged:

formula of std error:
Point differential estimation =
For 90 percent t= 1.860 Cl & 8 df
error of margin E = 
Lower bound =mean difference -E=0.461
Upper bound = mean difference+ E=7.206
In the above 90% confidence interval were the population mean= (0.461 , 7.206)
The vertex form is y=7(x+1)^2-3
Answer: 4.5 gallons
Step-by-step explanation:
Gallons of gas = # of miles / miles per gallon. Therefore:
153 miles/34 miles per gallon = 4.5 gallons
<span>the football team has 30 more players than the basketball
team, so the number of players on the football team is x= 30 + y.
Then you have to add on the extra ten players to each team so that the ratio
fits. Now the football team is </span>
<span>10 + 30 + y (or 40 + y) and the basketball team is 10
+ y.
Next you need to divide the ratio by its respective parts since a third of the
football team is equal to half of the basketball team. So you end up with this
equation:
(40 + y)/3 = (10 + y)/2
multiply the three over to the other side to cancel it out. Same with
the two. So, now the equation is:
80 + 2y = 30 + 3y
Subtract the 30 from the 80 and the 2y from the 3y and you have your answer: y
= 50.
Go back up to the top where you found out that x = 30 + y and put the 50 in
place of the y, giving you x = 80</span>
