-0.8 would be the best estimate.
The data seem to have a negative correlation, since they are decreasing; this means our r-value will be negative.
Our two negative choices are -0.25 and -0.8. -0.8 would be a fairly strong correlation, whereas -0.25 would be a weak correlation. The data do seem to be fairly strongly related, so we will use -0.8.
Answer: B
Step-by-step explanation:
1. 50000+1700+2200 = 55300
2. To find 80% trade in free, all we have to do is figure out 80% of 5000 (because thats the cost of his original car) which is 4000. (5000/100 x 80 = 4000)
3. Then you want to subtract 55300 - 4000 because hes trading in the car which means to subtract from the price.
4. Lastly there is a 1200$ destination fee, so you add on 51300+1200 which equals to 52500
You said factor NOT solve for x.
x^2 - 3x + 2
(x - 2)(x - 1) = the product of two binomials.
