Robert went to the grocery store and purchased cans of soup and frozen dinners. each can of soup has 300 mg of sodium and each f
Paraphin [41]

There are 9 cans of soup and 5 cans of frozen dinner.

The variables used for soup and frozen dinner are x and y respectively.

Step-by-step explanation:

Let,

Soup = x

Frozen Dinner = y

According to given statement of sodium;

300x + 500y = 5200 eqn 1

And,

x + y = 14 eqn 2

Multiplying\ equation\ 2\ with\ 300\\300(x+y=14)\\300x+300y=4200\ Eqn 3\\

Subtracting Eqn 3 from Eqn 1;

(300x+500y)-(300x+300y)=5200-4200\\300x+500y-300x-300y=1000\\200y=1000\\y=\frac{1000}{200} \\y=5

Putting value of y in Eqn 1;

300x+500(5)=5200\\300x+2500=5200\\\\Subtracting\ 2500\ from\ both\ sides\ \\300x+2500-2500=5200-2500\\300x=2700\\x=\frac{2700}{300} \\x=9

There are 9 cans of soup and 5 cans of frozen dinner.

The variables used for soup and frozen dinner are x and y respectively.

What’s a absolute deviation
Sergeeva-Olga [200]

Answer:

Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.

Step-by-step explanation:

Maddox: |10-9| = 1

Enrique: |10-13| = 3

Gloria: |10-9| = 1

McKenna: |10-10| = 0

Asher: |10-9| = 1

Hannah: |10-9| =

Danielle: |10-10| = 0

Katy:  |10-10| = 0

Timothy: |10-11| = 1

Gentry: |10-9| = 1

Now you have the numbers:  1, 3, 1, 0, 1, 1, 0, 0, 1, 1,

Now find the mean of those numbers:

\frac{1 + 3+1+0+1+1+1+0+0+1+1}{10} =\frac{10}{10} =1

The absolute deviation is 1.
