Solve the equation

22 = -13 + a

The values of p and q are 11 and 3 respectively.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers. Simply said, the mean is the average of the values in the given collection. It indicates that values in a certain data collection are distributed equally.

Given that,

∑f = 40

=> 26+p+q = 40

=>p+q=40-26

=> p+q = 14 .......................(i)

∵ x bar = ∑xf/∑f

=>14.7 = 408+9p+27p / 40 (since, x bar = 14.7)

=>588 = 408+9p+27p

=>588 - 408= 9(p+3p)

=>180= 9(p+3p)

=>p+3q=20......................(ii)

Solving equations (i) and (ii)

=>p+3q -(p+q)=20-14

=>p+3q-p-q=6

=>2q=6

=>q=3

Substituting this value in equation (ii)

∴p+3=14 => p = 11

Hence, the values of p and q are 11 and 3 respectively.

The sides of the right triangle are as follows:

AC = 3.2 metres

AB = 12.4 metres

A right angle triangle is a triangle that has one of its angles as 90 degrees.  The sum of angles in a right triangle is 180 degrees.

Therefore, the sides of a right triangle can be found using trigonometric ratios.

Hence, let's find AC

tan 15 = opposite / adjacent

tan 15 = AC / 12

cross multiply

AC = 12 tan 15

AC = 12 × 0.26794919243

AC = 3.21539030917

AC = 3.2 metres

Let's find AB

cos 15 = adjacent / hypotenuse

cos 15 = 12 / AB

AB = 12 / cos 15

AB = 12 / 0.96592582628

AB = 12.423314503

The maximum of the equation y = -2x² +32x -12 is 116 and the range of the function is y ≤ 116.

The highest and smallest values of a function, respectively, can either be found inside a specific range or across the entire domain. They are sometimes referred to collectively as the function's extrema. The plural forms of a function's maximum and minimum are called maxima and minima, respectively.

Y= ax² + bx + c is the conventional form of this quadratic equation. The vertex of a quadratic function is its greatest value or smallest value. We locate the axis of symmetry to determine the x-coordinate of the vertex. This is determined by the equation x = -b/2a:

x = -32/2(-2) = -32/-4 = 8

To find the y-coordinate, plug this into the equation y  = -2(8²)+32(8)-12

y=-2(64) + 256 - 12 = -128+256-12 = 128-12 = 116

The coordinates of the vertex are (8, 116).

Look at the value of a to see if this is maximum or minimal. It is -2. This indicates that the parabola widens downward and that the vertex is a maximum because it is negative.

Therefore this is a maximum at y=116, which means the range will be less than or equal to this value of 116.

Answer:

1 balloon is = £2 and 1 cake is = £4

Step-by-step explanation:

this is true because 2 balloons = £4

and 3 cakes = £12 so 4 + 12 = 16 and also

4 balloons = £8

and 4 cakes = £16 so 8 + 16 = £24

this is one of the possible answers

Answer:

A cake is £3.50

A Balloon is £2.75

Step-by-step explanation:

Let b be balloons and c be cake

2 balloons and 3 cakes = £16 = 2b + 3c = 16

4 balloons and 4 cakes = £24 = 4b + 4c = 25

First times -2 to the first equation

-4b - 6c = -32

4b + 4c = 25

Now let's find c first by adding the two equations together.

-2c = -7

c = £3.50

Now put 3.50 back in the c

4b + 4(3.50) = 25

4b + 14 = 25

4b = 11

b = £2.75

An exponential function with a base greater than 1 will be increasing in nature.

This is because when the base of an exponential function is greater than 1, the exponent is raised to a power greater than 1, and the result will always be greater than the original number. This means that as the value of x increases, so too will the value of the function. To illustrate this, the formula for an exponential function with base b can be written as f(x) = b^x. As x increases, b^x will become larger and larger, resulting in a continually increasing function. For example, if b = 2, then f(x) = 2^x. As x increases, 2^x will increase exponentially, resulting in a function that is always increasing.

To find the median of a set of numbers, you first need to put the numbers in order from smallest to largest. Then, if there is an odd number of values, the median is the middle value. If there is an even number of values, the median is the average of the two middle values.

In this case, the set of numbers is already in order: [2, 4, 5, 6, 7, 8, 11]. There are 7 values, so the median is the middle value, which is 6.

Dialyzer re-use efficiency is largely determined by the fiber bundle volume (FBV).

This estimation is performed after the dialyzer has been pressure cleaned and may underrate the level of coagulated strands a patient really experiences while on dialysis.

The package's dimensions:

length = 32 in

width = level = 16 in

Volume of bundle = 8192 in³

The square-shaped package is depicted in the attached image.

Expect that the length is y in and that width = level = x in (since the base is a square)

This implies that the circumference is 4*x = 4x in

We are given that the greatest amount of length and circumference is 96.

This indicates:

This can be rewritten as: y + 4x = 96

The volume of the package can be calculated as follows: y = 96 - 4x..............> I

Volume is equal to the following: length * width * height * y * x * x = x2y in3 Substitute equation I for the following volume equation:

Volume = x2 (96-4x) = 96x2 - 4x3 in3 to achieve maximum volume:

dV/dx = 0 indicates that:

2(96) x - 4(3) x2 = 0 192x - 12x2 = 0 x (192-12x) = 0

either x = 0.......> This is rejected because the side cannot be zero or 192 - 12x = 0...............> 192 = 12x...............> x = 16 in.......> accepted

In Part (b), y = 96 - 4x = 96 - 4(16) = 96 - 64 = 32: obtaining a volume:

The zeros of the function y = x^2 - 4x - 5 = 0 are 5 and -1.

The given function is y = x^2 - 4x - 5 = 0

We know that the general form of a quadratic equation is:

ax^2 + bx + c =0

On comparing the given equation y = x^2 - 4x - 5 = 0 with the general form of a quadratic equation ax^2 + bx + c =0 we get that:

a= 1, b = -4, c = -5

On multiplying a and c, we get -5 and the factors of it are 1 and 5.

Hence we can break the equation into:

x^2 - 5x + x - 5 = 0

We can factor it into:

x (x -5) + 1 (x - 5) = 0

(x + 1) (x - 5) = 0
