The correlation Coefficient, R shows the degree or level of relationship between the dependent and independent variable. A positive R value denotes a positive correlation while a negative R value denotes a negative relationship. R values should range between - 1 to +1 with values close to 1 and - 1 depicting strength while value of zero means no relationship exist.
Hence, R value of -0.90 depicts a strong negative relationship. Hence, higher speed are related to lower miles per gallon and vice versa.
13,500 at 5.2 for 8 years compounded semi-annually.
Total = Principal * (1 + rate/n) ^n * years
where "n" = number of compounding periods per year.
Total = 13,500 * (1 + .052 / 2) ^ 2 * 8
Total = 13,500 * (1.026) ^ 16
Total = 13,500 * 1.5078487226
Total = 20,355.96

55% of x is 70
0.55 times x=70
divide both sides by 0.55
127.27272727
round
127.3
