Answer:

$Angle = 54$

Step-by-step explanation:

Given

Kano = 45;

Kwara = 410;

Ogun = 105;

Ondo = 126;

Oyo = 154

Total Distribution = 840

Required

Determine the angle subtended by Ondo (in a pie chart)

The general formula to calculate subtended angle in a Pie chart is;

$Angle = 360 * \frac{Frequency}{Total\ Frequency}$

In this case of Ondo

Frequency = 126

Total Frequency = Total Distribution = 840

Substitute these values in the given formula;

$Angle = 360 * \frac{126}{840}$

$Angle = \frac{360 *126}{840}$

$Angle = \frac{45360}{840}$

$Angle = 54$

<em>Hence, the angle subtended by Ondo is 54</em>

What is true of the data in the Dot Plot check on that apply number of televisions per household?

Aliun [14]

Answer:

first and last

Step-by-step explanation:

Total observations:

3 + 7 + 7 + 4 + 1 = 22

There are 22 observations, so data from 22 households

Median position: (n + 1)/2

(22 + 1)/2 = 23/2 = 11.5th value

median is the average of 11th and 12th values, both are 2. So the average is also 2

Therefore, Centre is at 2

scoray [572]

Answer:

x = 52.5

Step-by-step explanation:

4x + 6(10) = 4.32(x + 10)

4x + 60 = 4.32x + 43.20

0.32x = 16.8

x= 52.5
