IN A CLASS OF 60 STUDENTS, 25 PLAYS BASKETBALL, 2O PLAY VOLLEYBALL, AND 10 STUDENTS PLAY BOTH OF THEM. HOW MANY STUDENTS PLAY NE

I am Lyosha [343]

Answer:

Step-by-step explanation:

We'll compare it with the study of sets, the most noticeable operation of which is:

n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

where,

n(A ∪ B) is the Union Set, i. e, the set that contains all the elements

n(A) is a subset of the Union Set

n(B) is another subset of the Union Set, and

n(A ∩ B) is the Intersection Set ,i.e, the set contains common elements from both A and B sets.

<h3>In the question:</h3>

n(A ∪ B) = ? (the total number of students in the class who are into the above mentioned sports)

Let set A contains the students who play basketball and set B, the students who play Volleyball.

n(A) = 25
n(B) = 20

10 students play both of them, i. e.,

n(A ∩ B) = 10 (as 10 students have common sports - Volleyball and Basketball)

Using the above operation:

=> n(A ∪ B) = n(A) + n(B) - n(A ∩ B)

=> n(A ∪ B) = 25 + 20 - 10

=> n(A ∪ B) = 35

<h3>Final Step to the Answer:</h3>

The total number of students in the class

= students into the given sports + students who don't play any of them

Total number of students in the class is 60
Total number fo students playing basketball and volleyball is 35

The students who play neither = 60 - 35

= 25

Select yes or no for each literal equation.

ch4aika [34]

Answer:

No, Yes, Yes

Step-by-step explanation:

$5x + 2y = 3$

2y = 3 - 5x

y = (3-5x) / 2

FALSE

$\frac{w + 8}{2} = p$

2P = w + 8

w = 2P - 8

TRUE

$ax + by = c$

by = c - ax

y = (c - ax) / b

TRUE

Express the function F in the form f ∘ g. (Enter your answers as a comma-separated list. Use non-identity functions for f(x) and

damaskus [11]

Answer:

$F(x) = f \circ g$

$f(x) = x + 2$ and $g(x) = x$

Step-by-step explanation:

Given

$F(x) = x + 2$

Required

Express as

$F(x) = f \circ g(x)$

In functions:

$f \circ\ g(x) = f(g(x))$

So, we have:

$f(g(x)) = x + 2$

g(x) can be set to x and f(x) to x + 2

Hence:

$F(x) = f \circ g$

When: $f(x) = x + 2$ and $g(x) = x$

Select the correct answer for each statement.

1.) Will yield consecutive odd integers.
k+10, k+12, k+14
or
k+2, k+3, k+4

The answer is k + 10, k +12 , k + 14

Because consecutive integers have difference of 2.

If k is odd, then k+10, k+12, and k+14 are consecutive odd integers.

For example, assume k = 1, then,

k+10=11
k+12=13
k+14=15

And 11, 13 and 15 are consecutive odd integers.

2.) Will yield consecutive integers.

k+1, k+2, k+3
or
k+6, k+8, k+10

The answer is k+1, k+2, k+3

Let k be any integer number, k+1, k+2, k+3 are consecutive integers.

For example, let k = 23

k+1=24
k+2=25
k+3=26

24,25, and 26 are consecutive integers.
