A function has access to parameters that are passed to it and any variables created within the function (local and function scope).

The variable names that a function has access to depend on the scope of the variables. Scope refers to the visibility of a variable within a program.

There are four different scopes that a variable can have in relation to a function:
Global scope -

A variable that is declared outside of a function has global scope.

This means that it can be accessed by any function within the program.
Local scope -

A variable that is declared within a function has local scope.

This means that it can only be accessed within the function in which it was declared.
Parameter scope -

A variable that is passed as a parameter to a function has parameter scope.

This means that it can only be accessed within the function in which it was passed.
Function scope -

A variable that is created within a function has function scope.

This means that it can only be accessed within the function in which it was created.

It does not have access to variables declared outside of the function (global scope) unless they are explicitly passed as parameters.

It is important to note that naming conflicts can occur if variable names are not chosen carefully, especially when dealing with global and local scope.

Therefore , the solution of the given problem of equation comes out to be the value of an is 12 when b is 147. Therefore, 12 is the right response.

In intricate algorithms, variable words are typically employed to demonstrate consistency between two opposing arguments. Equations are academic phrases that are used to demonstrate the equality of different academic figures. Consider the specifics of the above x + 7 suggestions. improving in this case provides b + 7 while constructing y + 7 before integrating.

Here,

The following values can be used to put up a proportion if the relationship between variables a and b is proportional:

=>  a / b = 4 / 49

The value of a when b is 147 can therefore be calculated using this ratio:

=>  a / 147 = 4 / 49

The unit price for a piece of cheese is $0.11 per pound.

To find the unit price, we need to divide the total cost by the total weight. In this case, we have 1.24 pounds of cheese that costs $11.25.

So, we can set up a proportion

1.24 pounds / $11.25 = x pounds / $1

To solve for x, we can cross-multiply

1.24 pounds * $1 = $11.25 * x pounds

1.24 = $11.25 * x

x = 1.24 / $11.25

The population size of the fish species after 5 years is approximately 99.

The population size of the fish species after t years is given by the exponential function P(t)=510(0.72)^t. To find the population size, we simply need to substitute the given value of t in the equation.

For example, if we want to find the population size after 5 years, we substitute t=5 in the equation:

P(5) = 510(0.72)^5

P(5) = 510*0.1934917632

P(5) = 98.680799232

P(5) ≈ 99.

Therefore, the population size of the fish species after 5 years is approximately 99.

We can determine whether the population is growing or decaying by examining the value of the base of the exponential function, which is 0.72 in this case. Since the base is less than 1, we know that the exponential function represents exponential decay. This means that the population of the fish species in the lake is decreasing over time, and the rate of decrease is determined by the value of the base. In this case, the population is decreasing by a factor of 0.72 each year.

What is z-test?

It is a statistical test to determine whether two population means are different at the time when the variances are known and the sample size is large. Also it is a hypothesis test in which the z-statistic maintains a normal distribution.

A random sample of 100 people was taken. Eighty-five of the people in the sample favored Candidate A. We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 80%.

So from the given information we have,

sample size (n)= 100

sample proportion ( p₁) = 0.85 [ 85 of the people in the sample favored  candidate A]

So, the null hypothesis ,

H₀ : p = 0.80

To find the population of the city, we need to find the total number of people living in the city. We know that there are 1350 people per square mile, so we can find the total number of people by multiplying the number of square miles in the city by the number of people per square mile.

The area of the city is the length times the width, so:

Area = Length x Width

Area = 12 miles x 8 miles

Area = 96 square miles

Now, we can find the population by multiplying the area by the number of people per square mile:

Population = Area x People per square mile

Population = 96 square miles x 1350 people per square mile

Population = 129,600 people

Therefore, the population of the city is 129,600 people.

Answer:

Step-by-step explanation:

You want the measures of x and ∠ECB in rectangle ABCD with center point E and AE=3x+6, BD=5x+19, ∠EBA=25°.

The diagonals of a rectangle are congruent and cross at their midponts. This means the triangles they form are all isosceles.

The value of x can be found by relating the length of a half-diagonal to the length of the whole diagonal.

  2·AE = BD

  2(3x +6) = 5x +19 . . . . . . . substitute given lengths

  6x +12 = 5x +19 . . . . . eliminate parentheses

  x = 7 . . . . . . . . . . . subtract 5x+12

The value of x is 7.

Angle EBC is the complement of angle EBA, so its measure is ...

  ∠EBC = 90° -∠EBA

  ∠EBC = 90° -25° = 65°

Angle ECB is the other base angle of isosceles triangle BCE, so has the same measure as ∠EBC.

  ∠ECB = 65°

__

Additional comment

You know the corner angles of a rectangle are 90°, which is what makes angles EBA and EBC complementary.

With x = 7, AE = 27 and BD = 54. The full diagonal is double the length of the half-diagonal, as you expect.

The statement is true: If x and y are linearly independent, and if z is in Span {x, y}, then {x, y, z} is linearly dependent.

The statement is true.
Let's first understand the terms used:
Linearly independent:

A set of vectors is linearly independent if none of them can be expressed as a linear combination of the other vectors. In other words, no vector in the set can be written as a sum of scalar multiples of the other vectors.
Span:

The span of a set of vectors is the set of all linear combinations of those vectors.

In this case, Span[tex]{x, y}[/tex] is the set of all vectors that can be formed by adding scalar multiples of x and y.
Now, let's consider the given statement:
If x and y are linearly independent, it means that neither x nor y can be expressed as a linear combination of the other. However, it is given that z is in the Span[tex]{x, y}.[/tex]

This means that z can be expressed as a linear combination of x and y:
[tex]z = ax + by[/tex], where a and b are scalar constants.
Let's analyze the set[tex]{x, y, z}[/tex]. We know that z can be expressed as a linear combination of x and y, as shown above. This implies that the set [tex]{x, y, z}[/tex]is linearly dependent, because one vector (z) can be expressed as a linear combination of the others [tex](x and y)[/tex].

Thus, the statement is true: If x and y are linearly independent, and if z is in Span[tex]{x, y}[/tex], then[tex]{x, y, z}[/tex] is linearly dependent.

The volume of solid B is about 7π cubic meters, which is approximately 21.99 cubic meters when rounded to the nearest thousandth.

The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. Since solids A and B are similar, they have the same shape, but different sizes.

Let V₁ be the volume of solid A, and V₂ be the volume of solid B. The scale factor k from solid A to solid B is 1/4, which means that the dimensions of solid B are 1/4 of the dimensions of solid A.

We can find the radius and height of solid B by multiplying the radius and height of solid A by 1/4. Therefore, we have:

V₂ = π(r/4)²(h/4) = (π/16)rh²

We are given that V₁ = 112π cubic meters, so we can solve for rh²:

112π = πr²h

rh² = 112

Substituting into the formula for V₂, we get:

V₂ = (π/16)rh² = (π/16)(112) = 7π

We can construct a shape of area 4 square meters using the four shapes square, rectangle, triangle and parallelogram.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

The area of a plane figure is the area that its perimeter encloses. The amount of units in a figure determines its area. Area is measured in square units like cm² and m². Area of a shape is a two dimensional quantity.

Area of a square =  side² (a²)

Area of a triangle = 1/2 × base length × height (1/2×b×h)

Area of a rectangle = length × breadth ( l×b )

Area of a parallelogram = base length × height ( b×h)

Consider the square of side 1 m

Area = 1 × 1 = 1 m²

Now consider the triangle of base length , b = 1/2 m and height, h = 2 m

∴ Area = 1/2×1/2×2 = 1/2 m²

Once more , area of the parallelogram of side 1 m and height 2 m is given by

Area = 1×2= 2 m²

For the rectangle of length 1/2 m and breadth 1 m

Area = l × b = 1/2 × 1 = 1/2 m²

∴ Total area = 1 + 1/2 + 2 + 1/2 = 4 square meter.

What is an Equations?

Equations are mathematical statements with two algebraic expressions on either side of an equals (=) sign. It illustrates the equality between the expressions written on the left and right sides. To determine the value of a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.

To eliminate the variable x, we can add the two equations together. This will result in the x variable being eliminated, leaving us with an equation in terms of y:

(x - 7y) + (-x + 8y) = -45 + 51

Simplifying and solving for y, we get:

y = 6

Now that we know the value of y, we can substitute it into one of the original equations to solve for x. Using the first equation:

x - 7(6) = -45

Simplifying and solving for x, we get:

x = -3
