You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and tw
VashaNatasha [74]

Answer: Cost per pair of jeans = $ 20

Cost per pair of shorts = $12

Cost per shirt = $8

Step-by-step explanation:

Let x= cost per pair of jeans

y = Cost per pair of shorts

z= cost per shirt.

For you, total cost = x+4y+2z= 84

For your friend,  total cost = 2x+y+3z=76

For cousin, total cost = x+2y+z= 52

Required system:

x+4y+2z=84\ (i)\\ 2x+y+3z=76\ (ii)\\ x+2y+z=52\ (iii)

from (i), x=84-4y-2z    (*)

put this in (ii) and (iii) we get

2\left(84-4y-2z\right)+y+3z=76\\\Rightarrow\ -7y-z+168=76\ (iv)\\\\ 84-4y-2z+2y+z=52\\\Rightarrow\ -2y-z+84=52 \ (v)

from (iv), y=-\frac{z-92}{7}\ (vi)

\mathrm{Subsititute\:}y=-\frac{z-92}{7}\ \text{in}\ (v)

-2\left(-\frac{z-92}{7}\right)-z+84=52\\\\\Rightarrow\ -2\left(-\frac{z-92}{7}\right)-z=-32\\\\\Rightarrow\ -\frac{5z}{7}-\frac{184}{7}=-32\\\\\Rightarrow\ -5z-184=-224\\\\\Rightarrow\ -5z=-40\\\\\Rightarrow\ z=8

\mathrm{Subsititute\:}z=8\text{ in (vi)}

y=-\frac{8-92}{7}\\\\\Rightarrow \ y=12

\mathrm{Subsititute\:}z=8,\:y=12\text{ in (*)}

x=84-4\cdot \:12-2\cdot \:8\\\\\Rightarrow\ x= 20

Hence, x= 20, y= 12 , z=8

So, Cost per pair of jeans = $ 20

Cost per pair of shorts = $12

Cost per shirt = $8

A Thurstone scale was constructed to measure creativity. The scale scores ranged from 1 to 13. If the scale was properly constru
Sonja [21]

Answer: A person with a score of 6 was more creative than a person with a score of 5

Step-by-step explanation: The Thurstone scale is usually employed in the representation of non-numerical attributes such as creativity, like or dislike, understanding and so on. in a numerical format usually in questionnaires or surveys in other to denote the level of agreement or disagreement with the statement or create ranking. However, despite being represented in numerical format to create distinction and processing. Variables measured cannot be subjected to mathematical calculation.

In the scenario above, creativity is represented in numerical format to show the level of creativity such that individuals with higher numbers are deemed more creative than those with lesser figures. However, it is wrong to Infer that an individual with creativity score of 6 is twice as creative as those with a creativity of 3.

IT just shows that individuals with 6 are more creativity than those with 5 and so on.
