Aresearcher conducts an experiment comparing three treatment conditions. the data consist of n =20 scores for each treatment condition. a. if the researcher used an independent-measures design, then how many individuals were needed for the study and what are the df-values for the f-ratio? explain in detail and show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts of the answers. b. if the researcher used a repeated measures-design, then how many individuals were needed for the study and what are the df-values for the f-ratio? explain in detail and show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts of the answers.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
