From the set given, the variables we look is as follows

Cricket only

let the number of children for cricket be c = 15

cricket only = 15 - (8 - 5) - (6 - 5) - 5

= 15 - 3 - 1 - 5

= 6

neither cricket tennis nor swimming

tennis only = 18 - (8 - 5) - (9 - 5) - 5

= 18 - 3 - 4 - 5

= 6

swimming only = 17 - (6 - 5) - (9 - 5) - 5

= 17 - 1 - 4 - 5

= 7

tennis and swimming only = 9 - 5 = 4

tennis and cricket only = 8 - 5 = 3

swimming and cricket only = 6 - 5 = 1

tennis cricket and swimming = 5

cricket only = 6

neither cricket tennis nor swimming = all the children - sum of the variables found

= 32 - (6 + 6 + 7 + 4 + 3 + 1 + 5)

In a picture we have a triangle with 3 sides. Sides are a,8 and 2. The side a=2[tex]\sqrt{15}[/tex].

Given that,

In a picture we have a triangle with 3 sides.

sides are a,8 and 2.

by using Pythagorean theorem

The Pythagorean Theorem, generally referred to as Pythagoras' Theorem, is a basic relationship between a right triangle's three sides. The Pythagorean theorem states that, given a right triangle, which is a triangle in which one of the angles is 90 degrees, the hypotenuse, the right triangle's longest side, forms a square whose area is equal to the sum of the areas of its other two sides.

In other words, given that the triangle's longest side, c, is also its hypotenuse and that sides a and b are its other two sides:

a² + b² = c²

a²+(2)²=8²

a²+4=64

a²=64-4

a²=60

Take root on both sides

[tex]\sqrt{a^{2} } =\sqrt{60}[/tex]

a=2[tex]\sqrt{15}[/tex]

Therefore, the side a=2[tex]\sqrt{15}[/tex].

Step-by-step explanation:

1/2 × 9/9 = 9/18

2/9 × 2/2 = 4/18

This means we have 9/18 and 4/18 left in the circle. Because these fractions have a common denominator, we can now subtract them from the whole to find the shaded portion:

18/18 - 9/18 - 4/18 = 5/18

The shaded portion is 5/18, which is already in simplest form.

Step-by-step explanation:

Part A: Yes, there is a correlation between the number of hours students spent studying and the score on the music test because  As we increase the hours of studying by 0.5 hours, then the music score increases by 2.

Part B: A function that best fits the data is; y = 60 + 4x

Part C: The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.

We have given the table below showing the data:

Number of hours spent studying (x) 0 0.5 1 1.5 2 2.5 3 3.5 4

Score on music test (y) 60 62 64 66 68 70 72 74 76

A) As we increase the hours of studying by 0.5 hours, then the music score increases by 2.

B) The function which best fits the data for the correlation from the above is; y = 60 + 4x

C) The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.

The slope of the above equation represents the rate of increase in music score with respect to an increase in the number of hours spent on studying.

The y-intercept gives the music score when the number of hours spent on studying is zero.

The length of the first, second, third pieces of sidings are 8 ft, 24ft and 32 ft respectively.

The 64 ft piece of siding is cut into three pieces so that the second piece is  three times as long as the first piece and the third piece is four times as long as the first piece.

The length of the three pieces of siding can be found as follows:

x = length of the first piece

Therefore,

Second piece = 3x

Third piece = 4x

Hence,

x + 3x + 4x = 64

8x = 64

divide both sides by 8

x = 64 / 8

x = 8

Therefore, the length of all the pieces are as follows;

First piece = 8 ft

The final answer in scientific notation with the correct number of significant digits, and label with the correct units is 4.1 * 10^6 square ft

The dimensions of the field are given as

Length = 3.3 * 10^3

Width = 2.5 * 10^3

From the question, we have

Half of the field is used to grow crops

This means that the area of the portion of the field that has crops growing is

Area = 1/2 * Length * Width

So, we have

Area = 1/2 * 3.3 * 10^3 * 2.5 * 10^3

Evaluate the product

Area = 4.125 * 10^6

In (a), we have

Area = 4.125 * 10^6

The units are 2 significant digits

The equation of a line that passes through the given point (4, 3) and is perpendicular to y = 2x + 2 is given by: y = -x/2 + 5.

The slope of a line simply refers to the gradient of a line and it's typically used to describe both the ratio, direction and steepness of an equation of a straight line.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

y = mx + c ≡  y = 2x + 2

m₂ = 2

For perpendicularity, we have:

m₁ × m₂ = -1

m₁ × 2 = -1

m₁ = -1/2.

Next, we would use the point-slope form to write the equation of this line at point (4, 3):

y - y₁ = m(x - x₁)

y - 3 = -1/2(x - 4)

y - 3 = -x/2 + 2

y = -x/2 + 2 + 3

What is Mean value theorem?

Mean value theorem states that if a function f is continuous on the closed interval [a ,b] and differentiable on the open interval (a ,b), then there exists a point c in the interval (a, b) such that f'(c) is equal to the function's average rate of change over [a, b].

That is;   [tex]f'(c) = \frac{f((b) - f(a)}{b - a}[/tex]

Given that;

⇒ f(0) = -1 and f′(x) ≤ 6 for all values of x.

Now, According to Mean value theorem;

[tex]f'(x) = \frac{f(4) - f(0)}{4 - 0}[/tex]

Since, f′(x) ≤ 6

Hence,

[tex]f'(x) \leq 6\\\\ \frac{f(4) - f(0)}{4 - 0}\leq 6\\\\ f(4) -(-1) \leq 24\\\\f(4) \leq 23[/tex]
