I believe its D.
Are you sure?
The equation y = 4.75x + 20 gives the cost y of towing a car if the car is towed x miles. According to the model, what is the best estimate of the cost for towing a car 22 miles? $24.75 $46.25 $104.50 $124.50
Well its not negative so it wouldn't decline, and 40 doesn't represent the hourly cost so yeah. lol cx
thanks! can you help with the other question?
\[\large y = 4.75x + 20\] where 'x' is the number of miles...so since we want to know the cost to go 22 miles we have \[\large y = 4.75(22) + 20\] \[\large y = 104.5 + 20\] \[\large y = 124.5\]
Yeah. Briefly. The answer for the second is 104.50
4.75(22) = 104.50
...close...but there is a constant added after that
so that is not the answer?
*refers to my post above :)
would it be 124?
The correlation coefficient (r) between the number of miles driven x and the number of gallons of gasoline used y is 0.925. What percent of the variation in the number of gallons of gasoline can be explained by differences in the number of miles driven? 7.5% 14.4% 85.6% 92.5%
Oh i forgot about the 20.. Yeah, John's right. lolol. Most of these questions are easy you just plug in numbers for x or y and then just add or subtract or whatever.
okay what about that ^^^
Oh didn't see a reply So the correlation coefficient r = 0.925 What we need for variability is R^2 ...so .925^2 = 0.8556 And multiply that by 100 to get the percent which is 85.6%
Oh crap, I hate this one haha I remember the long tedious steps to do this So I'm gonna cheat...1 sec :P
lol okay thanks!
First choice sorry it took so long excel didnt wanna open for me lol :P
no worries! thankyou!!
Sorry, I'm literally trying so hard to turn all of my work in on time. Math is my worst subject.
