Answer:

1)

The total number of students in the 25-34 age group.

2)

10.9%

Step-by-step explanation:

We are given a table as follows:

Age Group       Male     Female        Marginal Total

18–24              5,640      6,432             12,072

25–34               1,843      2,450              4,293

35+                      1 ,069     2,124              3,193

Total               8,552      11,006      19,558

We know that the marginal total is the total of all the entries along the row i.e. it is the total number of students of the two genders in the given age group.

Hence,The marginal total 4,293 is 1. the total number of students in the 25-34 age group.

Also, The relative frequency of females in the 35-plus age group compared with the total number of students, expressed as a percentage, is 2. 10.9%.

( Since, the relative frequency is calculated as:

(Number of females in 35+ age group/Total number of students)×100

= (2124/19558)×100

=10.9% )

In the given system of equations, the value of x is 7.334 and the value of y is 7.714

<h3>Solving system of linear equations</h3>

From the question, we are to solve the given system of linear equations

The given system of linear equations is

3x + 7y = 76               ------------ (1)

9y + 5y = 108             ------------ (2)

From equation (2), solve for y

9y+ 5y = 108

14y = 108

y = 108/14

y = 7.714

Substitute the value of x into equation (1), to determine the value of x

3x + 7y = 76

3x + 7(7.714) = 76

3x + 53.998 = 76

Subtract 53.998 from both sides of the equation

3x + 53.998 - 53.998  = 76 - 53.998

3x = 22.002

Divide both sides of the equation by 3

3x/3 = 22.002/3

x = 7.334

Therefore,

x = 7.334 and y = 7.714

Name the 4Ps of marketing.
Allisa [31]

Answer:

Product – Attributes of an organization or offering within this segment include delivery system design, technology, quality, services provided and their availability.

Price – This silo of the marketing mix includes costs to users/supporters, payment periods, arrangements and terms. Note: Some have also argued “costs” are more than dollars … a full cost analysis should include emotional (for those seeking greater purpose, advancements, victory), sacrificial (for people giving time, energy, focus) and relational (what does one’s association with an organization do for their relationships … will people think more or less of them).

Place – An often-overlooked part of the marketing mix, this “P” covers strategy and executional elements surrounding service distribution channels, coverage, locations, logistics and e-services.

Promotion – Likely the most known aspect of the marketing mix, this piece considers strategies and tactics related to advertising, logo/identity and promotions. But it also covers development/fundraising, communications, events and public relations as they are all tools to be considered and deployed as part of the greater marketing and branding strategy.
