Jamal drew δlmn, in which m∠lmn = 90°. he then drew δpqr, which was a dilation of δlmn by a scale factor of 2 from the center of dilation at point m. which of these can be used to prove δlmn ~ δpqr by the aa similarity postulate?

a. m∠p ≅ m∠n; this can be confirmed by translating point p to point n.
b. segment lm = 2segment pq; this can be confirmed translating point p to point l.
c. m∠r ≅ m∠n; this can be confirmed by translating point r to point n.
d. segment mn = 2segment qr; this can be confirmed translating point r to point n.

expression #3 is not equivalent. the others are.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.

i cant fully remember all of the ranks, here are the ones i remember.

hand, ambitous, ace, genius.
