In a school of 685 students, there are 385 students involved in sports teams, and there are
svet-max [94.6K]

Answer:

A) check attached picture

B) 272

C) 0.4478

Step-by-step explanation:

From the information given ;

A) The Venn diagram of the information can be found in the attached picture.

B) Number of students involved in both team sports and music.

n(student in sports team) = 385

n(students involved in music) = 450

Number of students involved in both music and team sport = y

Number of students not involved in either team sport or music = 87

Total number of students = 650

Therefore,

n(music alone) = 450 - y

n(team sport alone) = 385 - y

Adding the following:

n(music alone) + n(team sport alone) + n( both music and team sport) + n(neither music nor team sport) = Total number of students

450 - y + 385 - y + y + 87 = 650

922 - y = 650

922 - 650 = y

y = 272

Therefore, number of students involved in both music and team sport = 272

C) probability of being involved in team sport or in music.

P(being involved in music) = (450 - 272) / 650 = 0.2738

P(being involved in team sport) = (385 - 272) / 650 = 0.1738

P(involved in both) = 272 / 650 = 0.4184

P(involved in neither) = 87 / 650 = 0.1338

P(being involved in team sport) or p(being involved in music)

P(being involved in team sport) + p(being involved in music)

0.1738 + 0.2738 = 0.4478

I need help With my homeworkTITLE: Interpret and write equations From Table
Anon25 [30]
<h2>Answer:</h2>

a) 20 will represent the set price of admission

b) 3 is the price of each ticket

c) x will be the total number of ticket bought

d) y will be the total amount of money spent.

<h2>Explanations:</h2>

The equation given is written in slope-intercept form of a line. The slope-intercept form is in the form y = mx +b

where

• m is the ,rate of change ,or slope

,

• b is the ,intercept, (constant)

Given the equation that represents the total amount of mney the hunter will spend expressed as y = 20 + 3x

a) Since 20 is a constant value, it is more like the initial price. Based on the question, 20 will represent the set price of admission.

b) 3 is the price of each ticket needed to go on the ride

c) x will be the total number of ticket bought for the rides

d) As mentioned earlier, y will be the total amount of money the hunter will spend for the ride including the admission price.
