Does Meteo’s data show a positive association or a negative associate? Explain how you know
marishachu [46]

It shows a positive correlation

Just go from the very left of the graph to the very right and see, if the points go up or down.

Or pick off some points to see the trend

(2,1) (3,2) and (5,4)

These points show that over time the number of typos go up with the number of pages printed.

ella [17]

Answer:

Answer the question below. Be sure to show your work
likoan [24]

ANSWER:

We have to find new side-lengths of PQR triangle.

Original sides are.

\begin{gathered} PQ\text{ = 8cm} \\ QR=17\operatorname{cm} \\ RP=15\operatorname{cm} \end{gathered}

After multiplying by 2.5 we get

\begin{gathered} PQ^{\prime}=2.5\times PQ=(8\times2.5)cm=20\operatorname{cm} \\ QR^{\prime}=(17\times2.5)cm=42.5\operatorname{cm} \\ RP^{\prime}=(15\times2.5)cm=37.5\operatorname{cm} \end{gathered}

These are the new sides of the P'Q'R' triangle.
