Answer:

MAD is 5.12

Step-by-step explanation:

The following data were obtained from the question:

42, 50, 54, 38, 48

Next, we shall determine the mean of the data. This can be obtained as follow:

Mean = summation X / n

n is the number of the data.

Summation X = 42 + 50 + 54 + 38 + 48

Summation X = 232

n = 5

Mean = summation X / n

Mean = 232 / 5

Mean = 46.4

Therefore, the mean of the data is 46.4

Finally, we shall determine the mean absolute deviation (MAD) of the data as follow:

MAD = summation |mean – X| /n

MAD = (|(46.4 – 42) + (46.4 – 50) + (46.4 – 54) + (46.4 – 38) + (46.4 – 48|) /5

MAD = |4.4 + 3.6 + 7.6 + 8.4 + 1.6| /5

MAD = 25.6/5

MAD = 5.12

Therefore, the mean absolute deviation (MAD) is 5.12

How do you identify the independent and dependent variables
expeople1 [14]

A dependent variable is a variable whose value depends upon an independent variable. A dependent variable is what is being measured in an experiment and or evaluated in a mathematical equation. And you can identify an independent variable pretty easily since its variation does not depend on another.

Pratap Puri rowed 14 miles down a river in 2 ​hours, but the return trip took him 3 and one half hours. Find the rate Pratap can
SOVA2 [1]

speed of current is 1.5 mi/hr

Answer:

let the rate in still water be x and rate of the current be y.

speed down the river is:

speed=distance/time

speed=14/2=7 mi/h

speed up the river is:

speed=(14)/(3.5)=4 mi/hr

thus total speed downstream and upstream will be:

x+y=7...i

x-y=4.......ii

adding the above equations i and ii we get:

2x=11

x=5.5 mi/hr

thus

y=5-5.5=1.5 mi/r

thus the speed in still waters is 5.5 mi/hr

speed of current is 1.5 mi/hr
