Answer:

Step-by-step explanation:

$Mean = \frac{Sum \ of \ all \ the \ data}{number \ of \ data}\\\\= \frac{3.8+5.1+4.1+3.8+3.3+3.6}{6}\\\\=\frac{23.7}{6}\\\\= 3.95$

Mean = 3.95

B) To find the median, arrange the data in ascending order

3.3 ; 3.6 , 3.8 ; 3.8 ; 4.1 ; 5.1

As number of data is even, median = Average of (n/2)th term and (n/2)th term +1

= Average of 3 and 4th term

$= \frac{3.8+3.8}{2}\\\\= 3.8\\$

Median = 3.8

C) 3.8 occurs two times.

So, Mode = 3.8

d) 14.6 is above the mean. So, if we add a data above the mean, then the mean will increase

e) If April (3.8) is deleted from chart, Mean will increase. If we remove a data below the mean, then mean will increase

If April is deleted from chart, there will be no change in median.

Still median will be 3.8 only

The height is 400 mm high.

60 reaches 300 by a factor of 5
so if you do 80 x 5 you get 400.

Answer:

(3,5)

1/3

Step-by-step explanation:

The equation is already in point-slope form. Therefore, both the point and slope can easily be found in the equation. Point slope form looks like $y-y_{1}=m\left(x-x_{1}\right)$ . In this the point is $(x_{1},y_{1})$ and the slope is m. So, the x value is 3 and the y value is 5, making the coordinate (3,5). Finally, the slope is 1/3.
