Step-by-step explanation:

This is a geometric sequence.

a = first term = 1

Common ratio = r = second term ÷ first term

= (3/5)÷ 1 = 3/5

$t_{n}=ar^{n-1}\\\\t_{8}=1*(\dfrac{3}{5})^{7}\\\\= \dfrac{3^{7}}{5^{7}}\\\\\\= \dfrac{2187}{78125}$

The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

<h3>What is relative frequency?</h3>

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

$f_r=\dfrac{11}{40}\\f_r=0.3$

In the percentage from,

$f_r={0.3}\times100\\f_r=30$

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

d) The Bar Chart is attached to this solution. It was constructed in the Ms Excel suite.

Step-by-step explanation:

a) The frequencies are simply the number of times each industry sector sent in a complaint. So, it's straight forward to present.

b) The percentage for each industry is done in comparison to the the total amount of complaints received.

Percentage for each industry = 100% × (Number of complaints from that industry)/(Total number of complaints)

Total amount of complaints received = 200

For Bank industry,

Percentage = 100% × (26/200) = 13%

For the Cable Industry,

Percentage = 100% × (44/200) = 22%

For Car industry,

Percentage = 100% × (42/200) = 21%

For Cell industry,

Percentage = 100% × (60/200) = 30%

For Collection industry,

Percentage = 100% × (28/200) = 14%

c) The industry with the highest number of complaints is the one with the highest frequency and percentage, and that is the Cell Industry.

d) The Bar Chart is attached to this solution. It was constructed in the Ms Excel suite.
