The way to convert counts into relative frequencies in a Two Way Relative Frequency Table is to divide the count by the total number of items
<h3>What is a Frequency Table?</h3>
This refers to the depiction of the number of times in which an event occurs in the form of a table.
Hence, when a two-way frequency table is used, it shows the visual representation of the possible relationship between different sets of data.
Please note that your question is incomplete as you did not provide the frequency table needed and also the trends and generalizations to find, so a general overview was given.

Answer:
11
Step-by-step explanation:
The two equations appear to be ...
- 12x +4y = 152
- 32x +12y = 420
These can be solved for y using Cramer's rule:
y = (152(32) -420(12))/(4(32) -12(12)) = -176/-16 = 11
The cost of the vegetarian lunch is 11.

<em>Comment on Cramer's Rule</em>
For equations ...
ax +by =c
dx +ey = f
The solutions are ...
x = (bf -ey)/(bd -ea)
y = (cd -fa)/(bd -ea) . . . . note the denominators are the same expression
Once you memorize the pattern of products, this can be the simplest way to solve a pair of equations--especially if you only need one of the variable values.

to find the volume of a cube its V= W x H x L
Answer:
The scale factor is ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Step-by-step explanation:
The volume of the original prism is ![V_P=980cm^3](https://tex.z-dn.net/?f=V_P%3D980cm%5E3)
The volume of the dilated prism is ![V_Q=3307.5cm^3](https://tex.z-dn.net/?f=V_Q%3D3307.5cm%5E3)
Let the scale factor be
.
To find the volume of the dilated prism, we multiplied by
.
![\Rightarrow 980k^3=3307.5](https://tex.z-dn.net/?f=%5CRightarrow%20980k%5E3%3D3307.5)
![\Rightarrow k^3=\frac{3307.5}{980}](https://tex.z-dn.net/?f=%5CRightarrow%20k%5E3%3D%5Cfrac%7B3307.5%7D%7B980%7D)
![\Rightarrow k^3=\frac{27}{8}](https://tex.z-dn.net/?f=%5CRightarrow%20k%5E3%3D%5Cfrac%7B27%7D%7B8%7D)
![\Rightarrow k=\sqrt[3]{\frac{27}{8}}](https://tex.z-dn.net/?f=%5CRightarrow%20k%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B27%7D%7B8%7D%7D)
![\Rightarrow k=\frac{3}{2}](https://tex.z-dn.net/?f=%5CRightarrow%20k%3D%5Cfrac%7B3%7D%7B2%7D)
