Answer:

Huan receives 3.33 pounds (£) every week

Step-by-step explanation:

We can calculate this by dividing the amount for 5 weeks and dividing by 5 to find the amount of pocket money for each week. 16.65/5 = 3.33, which means that he receives 3.33 pounds (£) every week for pocket money.

Are the ratios 2:3 and 4:6 equivalent? Explain your answer.<br> PLSS HELP ME
MrMuchimi

Answer: Yes

Step-by-step explanation:

2:3 is the same as (2/3) and 4:6 is the same as (4/6). (4/6) can be reduced by dividing both sides by 1/22: (4/6)*(1/2)/(1/2) = 2/3, They are the same.

Using the frequency table given, find the mean, median, and mode.
aalyn [17]

Answer:

Mean = 69

Mode = 66

<em />Median = 69<em />

<em />

Step-by-step explanation:

Given

The frequency table

Required

Determine the mean, median and mode

Calculating Mean

Mean = \frac{\sum fx}{\sum f}

Where

fx = product of frequency and inches

f = frequency

So;

Mean = \frac{63 * 2 + 65 * 1 + 66 * 4 + 67 * 3 + 68 * 1 + 69 * 2 + 70 * 2 + 71 * 1 + 72 * 3 + 74 * 2 + 75 * 2}{2 + 1 + 4 + 3 + 1 + 2 + 2 + 1 + 3 + 2 + 2}

Mean = \frac{1587}{23}

Mean = 69

Calculating Mode

Mode = 66

Because it highest frequency of 4

Calculating Median

Median = \frac{\sum f}{2}th\ position

Median = \frac{2 + 1 + 4 + 3 + 1 + 2 + 2 + 1 + 3 + 2 + 2}{2}th\ position

Median = \frac{23}{2}th\ position

Median = 11.5th\ position

Approximate

Median = 12th\ position

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 />

<em>Hence;</em>

<em />Median = 69<em />

What is the length of PR?
JulsSmile [24]

Answer:

x = 6

Step-by-step explanation:

Since the triangles are similar, we can use ratios to solve

20            24

--------- = ---------

5                x

Using cross products

20x = 24*5

20x = 120

Divide each side by 20

20x/20 = 120/2

x = 6
