The angle of labour, Conservative Lib Democrat Other is 138, 192, 24 and 6 degree respectively.

The table shows the votes of 900 people in the last elections.

Political Party    Frequency     Angle in

Labour                    345

Conservative          480

Lib Democrat           60

Other                        15

345 + 480 + 60 + 15 = 900

The total angle in a pie chart is 360

The angle for labour is = 360 (345 / 900) = 138 degree

The angle for Conservative is = 360 (480 / 900) = 192 degree

The angle for Lib democrate is = 360 (60 / 900) = 24 degree

The angle for others is = 360 (15 / 900) = 6 degree

Therefore, the angle of labour, Conservative Lib Democrat Other is 138, 192, 24 and 6 degree respectively.

The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's assume that number of drinks that Jordan and his children bought is x while the number of tacos is y.

The cost of drinks = 2.50x

Cost of tacos = 2y

Total cost 2.5x + 2y

2.5x + 2y = 26

Given that,

He bought 4 more tacos than drinks.

Therefore,

y = x + 4.

Hence "The system of equations that could be used to determine the number of drinks and the number of tacos that Jordan bought are 2.5x + 2y = 26 and y = x + 4".

The midpoint between the given figures are -2.5 and 5.5 respectively.

A midpoint is defined as that particular point that divides two separate figures into two equal halves or the centre of two endpoints on a number line.

That is;

point a + point b/2

The figures given are :

Point a = -3

Point b = -2

= -3 + -2/ 2

= -5/2

= -2.5

For points 4 and 7 ;

= 4 + 7 / 2

= 11/2

The statement mentions that the pool started empty, which implies that the graph must start at the point (0,0).

Then, the pool slowly filled, so the amount of water in the pool remained constant when Janie turned off the water and went for a walk.

Finally, thanks to a truck in the neighborhood the pool filled up quickly, and when it was filled the amount of water remained constant.

Therefore, the graph that best represents this situation is the one shown in option B.

The probability that exactly 10 customers will use the atm during the next noon lunch hour is 0.0948

From the question, we have the following parameters:

Average number of customers = 12

Number of customers = 10

The above parameters means that:

x = 10

λ = 12

The probability of a Poisson distribution is represented as

P(x) = λˣe⁻λ/x!

This gives

P(x = 12) = 10¹² * e⁻¹⁰/12!

Evaluate

P(x = 12) = 10¹² * e⁻¹⁰/479001600

Solving further, we have

P(x = 12) = 0.0948

Answer:

[tex]x=\frac{vw}{k-y}[/tex]

Step-by-step explanation:

The values of x and y in the triangle are 15 and 88 degrees.

A triangle is a polygon with 3 sides. The sum of angles in a triangle is 180 degrees.

A triangle can be classified base on its sides and angles as equilateral triangle, isosceles triangle and scalene triangles.

An equilateral triangle has three of its sides and angles equal to each other.

An isosceles triangle has 2 sides and angles equal to each other.

A scalene triangle has no sides equal to each other.

Therefore,

The other triangle on the left side is an equilateral triangle.

Therefore, all it sides and angles are equal.

Hence, each angle of the triangle is 60 degrees.

A traversal line cut across the sides of the parallel lines of the triangles formed.

Therefore,

60° = 4x

x = 60 / 4

x = 15

Therefore,

60 + y + 32 = 180(sum of angles in a triangle)

y = 180 - 92

Answer:

A' = (6, 3)

B' = (1, 1)

C' = (8, 7)

Step-by-step explanation:

Vertices of triangle ABC:

Given mapping rule:

(x, y) → (x + 4, y + 6)

This notation tells you that the x-coordinate is translated 4 units to the right, and the y-coordinate is translated 6 units up.

Substitute the coordinates of each point into the mapping rule to find the vertices of triangle A'B'C':

⇒ A' = (2 + 4, -3 + 6) = (6, 3)

⇒ B' = (-3 + 4, -5 + 6) = (1, 1)

⇒ C' = (4 + 4, 1 + 6) = (8, 7)

If two lines are perpendicular, it means that the slope of one line is equal to the negative reciprocal of the slope of the other line. Given a value, a/b, the negative reciprocal of a/b is - b/a.

From the information given, the slope of the red line is 2/5. This means that the slope of the green line which is perpendicular to the red line is - 5/2

Option D is correct

Percentage spent on transportation is 12%

Percentage spent on Property tax is 11%

Percentage spent on utilities is 9%

Percentage spent on food is 20%

Percentage spent on mortgage payment is 30%

Percentage spent on entertainment is 8%

Percentage spent on miscellaneous is 10%

What are the percentages?

Percentage is the fraction of a number expressed as a number out of 100. In order to convert a number of fraction to percentage, multiiply by 100. The sign that is used to represent percentage is %.

Percentage spent on transportation = (576 / 4800) x 100 = 12%

Percentage spent on Property tax = (528 / 4800) x 100 = 11%

Percentage spent on utilities = (432 / 4800) x 100 = 9%

Percentage spent on food = (960 / 4800) x 100 = 20%

Percentage spent on mortgage payment = (1440 / 4800) x 100 = 30%

Percentage spent on entertainment = (384 / 4800) x 100 = 8%

Percentage spent on miscellaneous = (480 / 4800) x 100 = 10%

The quadratic function of h (x) in vertex form will be as h(x) = (x + 2)² − 3

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the values of x and h (x) for the quadratic function is given by;

x = -3, -2, -1, 0, 1, 2, 3,

h (x) = -2, -3, -2, 1, 6, 13, 22

Consider the quadratic function as;

h (x) = ax² + bx + c

Now Substitute x = -3 and h (x) = -2 in quadratic function we get;

h (x) = ax² + bx + c

- 2 = a × (-3)² + b × -3 + c

- 2 = 9a - 3b + c

And, Plug x = -2 and h (x) = -3 in function we get;

h (x) = ax² + bx + c

- 3 = a × (-2)² + b × -2 + c

- 3 = 4a - 2b + c

And, plug x = -1 and h (x) = -2 in function we get;

h (x) = ax² + bx + c

- 2 = a × (-1)² + b × -1 + c

- 2 = a - b + c

After solving we get:

a = 1 , b = 4 and c = 1

Then

h (x) = ax² + bx + c

h (x) = 1 × x² + 4x + 1

h (x) = x² + 4x + 1

h (x) = x² + 4x + 4 - 4 + 1

h (x) = (x + 2)² - 3

Hence, The quadratic function of h (x) in vertex form will be as h(x) = (x + 2)² − 3
