What is the mean absolute deviation? Round to the nearest tenth.

Answers

Answer:

The mean absolute value is 7.7, when rounded to the nearest tenth.

Step-by-step explanation:

1.) To get the mean absolute deviation you have to find the mean first:

  • 32 + 35 + 20 + 16 + 28 + 13 = 144 ÷ 6 = 24

2.) Then, you have to find the difference of each element in your data set that is away from the mean. Then, you have to find the absolute values of the answers:

  • 32 - 24 = | 8 | → 8
  • 35 - 24 = | 11 | → 11
  • 20 - 24 = | -4 | → 4
  • 16 - 24 = | -8 | → 8
  • 28 - 24 = | 4 | → 4
  • 13 - 24 = | -11 | → 11

3.) Then, you have to find the mean of the absolute values:

  • 8 + 11 + 4 + 8 + 4 + 11 = 46 ÷ 6 = 7.6666666666666666666666666666667‬ = 7.7

A map has a scale of 1 cm : 20 km. Two cities are 2.5 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?A. 70 km

B. 52.5 km

C. 50 km

D. 150 km

Answers

Answer:

C. 50 km

Step-by-step explanation:

The scale on the map is,

1 cm : 20 km,

That is, the ratio of the scaled distance and actual distance = (1)/(20)

Let x be the actual distance between the two cities which are 2.5 cm apart on the map,

So, the ratio of scaled distance and actual distance = (2.5)/(x)

\implies (1)/(20)=(2.5)/(x)

x=20* 2.5

x=50

Hence, the actual distance between the cities is 50 km.

Option 'C' is correct.
so just use the rule of 3 simple 

1 cm -------- 20 km 
2,5 cm ----- x km 
----------------------------

 x = 2,5 *20/1 = 50 km

x = 50 km so choice C. is righ,correct sure
