The fuel efficiency increases for speeds up to 25 mph when it reaches a relative maximum efficiency of 54 mpg. The fuel efficiency then decreases for speeds between 25 mph and 41 mph, when it gets down to 37 mpg. Above 41 mph, efficiency increases again until it reaches 48 mpg at 60 mph. Finally the fuel efficiency rapidly decreases for speeds greater than 60 mph until lev king off at 17 miles per gallon. (This is from glencoe algebra 1 page 62)

What is the perimeter, p, of a rectangle that has a length of x + 8 and a width of y − 1? p = 2x + 2y + 18 p = 2x + 2y + 14 p = x + y − 9 p = x + y + 7

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
