Here's the complete question:

The mean number of people per household in eight households is six people. what is the total number of people in the eight households?

First and foremost,we should note that mean means the average of a given set of numbers.

Since the mean number of people per household in eight households is six people, the total number of people in the eight households would be calculated by multiplying 6 by 8. This would be:

= 6 × 8

Inga [223]

Answer:

Step-by-step explanation:

The sum of squares of the deviation from mean=sum(x-xbar)²=?

xbar=sumx/n

xbar=(12+6+15+9+18+12)/6=72/6=12

x x-xbar (x-xbar)²

12 12-12=0 0

6 6-12=-6 36

15 15-12=3 9

9 9-12=-3 9

18 18-12=6 36

12 12-12=0 0

sum(x-xbar)²=0+36+9+9+36+0=90

So, the sum of squares of the deviations from the mean is 90.

BigorU [14]

Answer:

Length of scale = 15 cm

Width of scale = 5 cm

Step-by-step explanation:

Dimensions of the kitchen of Mai are given as:

Length of kitchen = 6 m

Width of kitchen = 2 m

Scale to be used = 1 to 40

To find:

The drawing with labeling and dimensions of the scale drawing.

Solution:

First of all, let us understand about the concept of scaling.

Scaling is a method to represent big structures on paper.

For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.

Here, the scale factor used is 1 to 40.

i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.

40 units of kitchen = 1 unit of scale

1 unit of kitchen = $\frac{1}{40}$ units of scale

6 m of kitchen = $\frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm$

Length of scale = 15 cm

40 units of kitchen = 1 unit of scale

1 unit of kitchen = $\frac{1}{40}$ units of scale

2 m of kitchen = $\frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm$

Width of scale = 5 cm

Please refer to the attached image as well for representation of given scale.
