Answer:(c). No. Both variables must be quantativite
Step-by-step explanation:
Both variables must be quantitative because we can calculate Pearson correlation if they are both quantitative
If segments AB and CD are congruent, then they have equal lengths:
5x-2=2x+7.
Solve this equation.
1. Separate terms with x and without x in different sides:
5x-2x=7+2,
3x=9.
2. Divide by 3:
x=3.
Then CD=2x+7=2·3+7=6+7=13.
Answer: correct choice is B.
I believe the answer is 2.7 but I'm not sure...
