In a study, professor Michael LaCour-Little selected independent random samples of mortgages that were refinanced and mortgages that were not refinanced. (Source: Michael LaCour-Little, "Another Look at the Role of Borrower Characteristics in Predicting Mortgage Prepayments, " Journal of Housing Research, Volume 10, Issue 1.) Of the 115 refinanced mortgages, the mean mortgage rate was 8.62 with a sample standard deviation of 0.55. Of the 130 mortgages that were not refinanced, the mean mortgage rate was 8.09 with a sample standard deviation of 0.66. Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you call the sample of mortgages that were refinanced sample 1 and the sample of mortgages that were not refinanced sample 2. Organize the provided data by completing the following table:Sample 1 Sample 2n1= n2=u1= u2=M1= M2=S1= S2=

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
