Answer:
Step-by-step explanation:
Given
Represent Mugs with M and Refills with R
per refill
Required
Determine the equation
If 1 refill costs $1.50, then
R refills will cost 1.50 * R
The relationship between the given parameters is:
Substitute values for Total, M and Refills
Solve for 1.50R
<em>Hence, the equation to solve the value of R is </em><em></em>

Step-by-step explanation:
Given
The frequency table
Required
Determine the mean, median and mode
Calculating Mean
Where
fx = product of frequency and inches
f = frequency
So;
Calculating Mode
Because it highest frequency of 4
Calculating Median
Approximate
At this point we, need to get the cumulative frequency (CF)
<em>Inches ---- Frequency ---- CF</em>
<em>63 -------------2------------------2</em>
<em>65 -------------1------------------3</em>
<em>66 -------------4------------------7</em>
<em>67 -------------3------------------10</em>
<em>68 -------------1------------------11</em>
<em>69 -------------2------------------13</em>
<em>70 -------------2------------------15</em>
<em>71 -------------1------------------16</em>
<em>72 -------------3------------------19</em>
<em>74 -------------2------------------21</em>
<em>75 -------------2------------------23</em>
From the above table
Since the median fall in the 12th position, then we consider the following data
<em>69 -------------2------------------13</em>
<em>because it has a CF greater than 12</em>

<em>Hence;</em>
