Which statements describe a parallelogram that must be a rhombus?
select each correct answer.
1.parallelogram with congruent diagonals
2.parallelogram with a right angle
3.parallelogram with perpendicular diagonals
4.parallelogram with opposite sides congruent
5.parallelogram with a pair of congruent consecutive sides

3 and 5.

Step-by-step explanation:

A parallelogram which is a rhombus has perpendicular diagonals.

Also a parallelogram which is a rhombus has a pair of congruent consecutive sides.

To determine if the data set has a good linear relationship, you have to interpret the correlation coefficient, r. It ranges between -1 to 1. The closer it gets to the whole integers, either -1 or 1, the better is the linear fit. The negative sign designates that there is an inverse linear relationship, while the positive is directly proportional. 

Among the correlation coefficients stated in the problem, Aaliyah and Julio are closer to the integers. Thus, the answer is letter A.
