Answer:

The given data is not normal.

Step-by-step explanation:

We are given the following data:

30, 59, 69, 50, 58, 71, 55, 43, 3,  66, 52, 56, 62, 36, 13, 29, 17, 31

Condition for normality:

Mean = Mode = Median

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

Mean =\displaystyle\frac{800}{18} = 44.44

Mode is the most frequent observation of the data.

Since all the value appeared once, there is no mode.

Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}

Sorted data: 3, 13, 17, 29, 30, 31, 36, 43, 50, 52, 55, 56, 58, 59, 62, 66, 69, 71

Median =

=\dfrac{9^{th}+10^{th}}{2} = \dfrac{50+52}{2}=51

Since the mean, mode and median of data are not equal, the data is not normal.

Answer & Step-by-step explanation:

Since you looking for the width and you are given the length and the area, then you will divide the area by the length.

(10x² + 5x) ÷ 5x

You can also turn this into a fraction so you can know what you are dividing.

\frac{10x^2+5x}{5x}

So, your width is 2x + 1

Kipish [7]

Answer:

y = 39

Step-by-step explanation:

550 x \pi = \pi r^{2} x 11 + y

550 x \frac{7}{22} = \frac{7}{22} x 11 x 11 + y

550 x \frac{7}{22} x \frac{22}{7} = 11 x 11 + y

550 = 11 x 11 + y

\frac{550}{11} = \frac{11}{11} x 11 + y

50 = 11 + y

50 - 11 = y

39 = y
