Question

Question 1: The equation represents the line of best fit for a relationship, The quadratic model is most suitable for the data when the constant. are The 50 percentile of a set of data is the same as the of that data I When dealing with mortgages, the interest rate is always compounded An exponential function involves having the variable, x, as the A linear model has a constant and a constant Given that 0° SZB S180°, there will be angle(s) when solving sinB -0.1795.

Answer 1

supresents the line of best fit for a The equation y= math relationship A line best fit is a that test represents the straight line of . data on a scatter point y are constant The quadratic model is mbst suitable is most suitable for the dole when the Coefficients for quadratic model, ax² +bx+c , a,bie care constants eato The 50th percentile of a set dota is the some as the medion that dota There are n elements in a in a sequence of asunding order then Soth percentile on the median in on the median is given for nt Odd The middle tirom of median is given of date of os, له of the sequence 08 for th tum + (with them te fram mudian icl quien nt even , ni 2 2 when dealing with mortages, the interest o the interest rate is compounded Monthly The interest on loons cond morloges that were ie a smooth monthly payment until the loan has been feid - is ofter compounded monthly comortized,
