The ratio of men to women at Sarah’s party is 4 to 5. If there are fifteen women at the party, how many men are there? How many guests are there all together?

Answers

Answer:

12 Men, 27 men and women together.

Step-by-step explanation:

Well we know there are 15 women. The ratio of men to women is 4:5 so that means every 4 men, there are 5 women. If we divide 15 by 5, we get 3. Now we multiply 3 to the number of men which is 4 because what happens to one part of the ratio then happens to the next. Added together, 12 plus 15 equals 27 so that is the total. Hope this helps!

You are doing marketing research to find out the purchasing potential of students in the community based on the latest senses there are 9860 students in a population of 602400 people what percent of the total population is students

Answers

Answer:

In statistics, scientists or researchers gather data to represent the existing number of population audience that they should target. Statisticians usually lump these data and present them in terms of mean, median or mode. To be more accurate, percentage could also be used. Percentage is generally defined as the number of a specific parameter per 100 units of the whole. In this case, the percentage is defined as the number of students per 100 people of the whole population. The working equation to be used is:

Percentage = Number of Students/Number of Population * 100%

Percentage = 9,860/62,400 * 100

Percentage = 15.8%

Hence, out of the total population, 15.8% are students.

or

Number of students = 9860

Total Population = 62,400

Percentage of students in the population can be calculated by:

(Number of students/Total population) x 100%

Using the values, we get:

Percentage of students = (9860/62400) x 100% = 15.80%

Thus, students constitute 15.80% of the entire population

a rectangular prism has a width of 0.5 a height of 4 and a length of 1.5, what is the surface area of the rectangular prism?

Answers

Answer:

The surface area of the rectangular prism is 17.5

Step-by-step explanation:

We are given:

Width of rectangular prism (w) = 0.5

Length of rectangular prism (l) = 1.5

Height of rectangular prism (h) = 4

We need to find the surface area of the rectangular prism.

The formula used is: [tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)[/tex]

Putting values and finding the surface area of the rectangular prism

[tex]Surface \ area \ of \ the \ rectangular \ prism=2(lw+lh+wh)\\Surface \ area \ of \ the \ rectangular \ prism=2((1.5)(0.5)+(1.5)(4)+(0.5)(4))\\Surface \ area \ of \ the \ rectangular \ prism=2(0.75+6+2)\\Surface \ area \ of \ the \ rectangular \ prism=2(8.75)\\Surface \ area \ of \ the \ rectangular \ prism=17.5[/tex]

So, the surface area of the rectangular prism is 17.5
