A data set consists of the data given below plus one more data point. When the additional point is included in the data set the

belka [17]

Answer:

Value of additional data point is 31.

Step-by-step explanation:

We are given the following data set:

34, 18, 18, 40, 11, 22, 30, 25, 19, 21, 45 34, 18, 18, 40, 11, 22, 30, 25, 19, 21, 45

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{487}{20} = 24.35$

The old mean is 24.35

A new data was added in the data. The new mean is 24.667

We have to find the value of additional point.

Let x be the added point in the data set.

Thus, we can write:

$24.667 = \displaystyle\frac{487+x}{21}\\\\x = 21(24.667)-487 = 31.007 \approx 31$

Thus, value of additional data point is 31

Select the correct answer.

alexira [117]

Answer:

$\huge\boxed{A.\ -\dfrac{9}{4}+2i}$

Step-by-step explanation:

The standard form of a complex number:

$z=a+bi\\\\a,\ b\in\mathbb{R}$

$3i+\left(\dfrac{3}{4}+2i\right)-(3+3i)=3i+\dfrac{3}{4}+2i-3-3i\\\\=\left(\dfrac{3}{4}-3\right)+(3+2-3)i=-2\dfrac{1}{4}+2i=-\dfrac{9}{4}+2i$
