On monday maggie ran n miles, on tuesday she ran 90% of the number of miles that she ran on monday. on wednesday she ran 50% of
Andrew [12]

Step-by-step explanation:

On Monday maggie ran n miles.

On Tuesday, she she ran 90% of the number of miles that she ran on Monday i.e \dfrac{90}{100}\times n=0.9n.

On Wednesday, she ran 50% of the number of miles that she ran on Tuesday i.e. \dfrac{50}{100}\times 0.9n=0.45n

First expression : n+0.9n = 1.9 n

Second expression : n + 0.9 n + 0.45 n = 2.35 n

Hence, this is the required solution.

Choose the scatter plot that shows a negative correlation.
Alenkinab [10]

Negative correlation between two variables means when x is increasing but y is decreasing or vice versa.

First graph of suffered animals and children shows a positive slope which means if age of child increasing then numbers of suffered animal is also increasing.So, the first graph show a positive correclation.

Second graph of survey of adults doesn't represnt any distinct relationship as the data scattered randomly everywhere in the graph. So, it's showsa very week correlation.

Third graph of speed and MPG shows a negative slope as speed is increasing then MPG is decreasing. So, the third graph (speed and MPG) shows a negative correlation.
