A Venn diagram exists as an illustration that utilizes circles to illustrate the relationships among things or finite groups of things. Circles that overlap include a commonality while circles that do not overlap do not share those traits. Venn diagrams permit visually illustrating the similarities and contrasts between two concepts.

Let M =sets of students who had taken mathematics

     C= sets of students who had taken chemistry

     P= represent sets of students who had taken physics

From the given information, we have

n(M) = 64 , n(C) = 94, n(P) = 58,

n(MnP) = 28, n(MnC) = 26, n(CnP) = 22

n(MnCnP) = 14​​​​​​​

No. of students who had taken only Math :

= n(M) - [n(MnP) + n(MnC) - n(MnCnP)]

= 64 - [28+26-14]

= 64 - 40

= 24​​​​​​​

No. of students who had taken only Chemistry

= n(C) - [n(MnC) + n(CnP) - n(MnCnP)]

= 94 - [26+22-14]

= 94 - 34

= 60

No. of students who had taken only Physics

= n(P) - [n(MnP) + n(CnP) - n(MnCnP)]

= 58 - [28+22-14]

= 58 - 36

= 22

Total no. of students who had taken only one course

= 24 + 60 + 22

= 106

Answer:

−31π/36 = -15.5°

Step-by-step explanation:

We need to convert −31π/36 to degrees.

The conversion from radian to degrees is calculated as follows :

[tex]\text{Degrees}=\dfrac{180}{\pi }\times \text{radian}\\\\=\dfrac{180}{\pi}\times \dfrac{-31\pi }{360}\\\\=-15.5^{\circ}[/tex]

So, −31π/36 is equal to -15.5 degrees.

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

[tex]Slope, \ m = \mathbf{ \dfrac{y_2 - y_1}{x_2 - x_1}}[/tex]

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

[tex]m = \dfrac{-16 - (-4)}{2 - 0} = \dfrac{-16 + 4}{2} = \dfrac{-12}{2} = \mathbf{ -6}[/tex]

Answer:

[tex]y = \frac{1}{2}x - 2[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Determine the linear equation

First, we need to calculate the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph, the following relationships exist:

[tex](x_1,y_1) = (4,0)[/tex]

[tex](x_2,y_2) = (10,3)[/tex]

So, the expression for calculating slope becomes:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{3-0}{10-4}[/tex]

[tex]m = \frac{3}{6}[/tex]

[tex]m = \frac{1}{2}[/tex]

Next, we calculate the equation using:

[tex]y - y_2 = m(x - x_2)[/tex]

This gives:

[tex]y - 3 = \frac{1}{2}(x - 10)[/tex]

Open bracket

[tex]y - 3 = \frac{1}{2}x - 5[/tex]

Make y the subject:

[tex]y = \frac{1}{2}x - 5+3[/tex]

[tex]y = \frac{1}{2}x - 2[/tex]

Given the following:

x = 7

y = 4

Required:

Find the value of x + 2y.

Therefore, substitute x = 7 and y = 4 into the algebraic expression, x + 2y.

(7) + 2(4) = 7 + 8

x + 2y = 15

Therefore, given that if x = 7 and y = 4, the value of x + 2y = 15

Answer:

Let the larger number = y and the smaller number = x.

The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,

y = 2x - 10

The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,

x + y = 38

Since y = 2x - 10, we rewrite the lower equation as:

x + (2x - 10) = 38

Solving:

3x - 10 = 38

3x = 48

x = 16

The lesser number is 16 and the greater number is 2(16) - 10 or 22.
