Step-by-step explanation:

Negative linear correlation between variables.

The statement "The more you save (x), the less you spend (y)" suggests a negative linear correlation between the variables x and y. In a negative linear correlation, as one variable increases, the other variable decreases at a constant rate.

In this case, as the amount saved (x) increases, the amount spent (y) decreases. This implies that if someone saves more money, they tend to spend less money. It is important to note that correlation does not necessarily imply causation.

In other words, just because there is a negative linear correlation between the amount saved and the amount spent, it does not mean that saving more money causes people to spend less. There may be other factors that influence both variables. Nonetheless, understanding the nature of the correlation between variables can be useful in making predictions and analyzing data.

From the tape diagram, your allowance and your friends' allowance is $48 and $32 respectively.

What is tape diagram?

A tape diagram is a visual representation that looks like a piece of tape and is used to help with ratio calculations, addition, subtraction, and most frequently multiplication. A divided bar model, fraction strip, length model, or strip diagram are other names for it. It is employed in mathematics education to help elementary school-aged children solve word problems. Students can use a tape diagram as a pictorial model to represent a mathematical relationship or to better understand a mathematical concept. Although they are frequently used with word problems, tape diagrams are helpful for solving many different kinds of math problems.

Let the ratio is given by 3:2 and total is 5
hence, 5 parts represent $80, so each part represents= 80/5= 16
hence, your allowance is 3×16 =48 and your friend allowance is 2×16= 32

Given the circle, we can see the following facts:

Diameter= 24 ft ----> radius= 12 ft

Total arc length = 360°

The arc of a semi-circle is equal to 360/2 = 180 degrees

The red labeled arc is given by the difference between 360, the other 60 degrees and the semi-circle,

360° - 180° - 60° = 120°

So, representing this as a radian form:

By solving the given equation f(x) = \(x^{2} +3x-40\), the zeroes are -3 and 5.

To solve the given equation we have to do the factorization.

What is factorization: Factorization is the method of writing numbers as the product of their factors or divisors.  In other words, we can say finding what to multiply together to get an expression.

To do the factorization, we have to follow the steps as shown below:

 \(x^{2} +3x-40\) \(= 0\)

\(-40 = 8 * -5\\\)                        [ multiplication of 8 and -5 is -40]

\(x^{2}+8x-5x -40\) \(= 0\)

\(x(x+8) -5(x+8)\) \(= 0\)

\((x-5)(x+8)\) \(= 0\)

\(x = 5\)   and  \(x = -8\)              [ The roots or zeroes]

From the above solution, we can conclude that the zeros of the given function \(x^{2} +3x-40\) are 5 and -8.

To determine the values of b, c, and d in the polynomial f(x) = \(x^3 + bx^2\)+ cx + d, we find that b can be expressed as -16 + t, c as t/3, and d as -20, where t is a parameter that can take any real value. These values satisfy the conditions of the remainder when f(x) is divided by (x+1) and (x+3), as well as f(x) crossing the y-axis at -20.

To determine the values of b, 5, and d in the polynomial f(x) = x^3 + bx^2 + cx + d, we can use the given conditions:

When f(x) is divided by (x + 1), the remainder is -5.

When we divide f(x) by (x + 1), the remainder is given by f(-1) =\((-1)^3 + b(-1)^2\)+ c(-1) + d = -1 + b - c + d = -5.

When f(x) is divided by (x + 3), the remainder is 1.

When we divide f(x) by (x + 3), the remainder is given by f(-3) =\((-3)^3 + b(-3)^2\) + c(-3) + d = -27 + 9b - 3c + d = 1.

f(x) crosses the y-axis at -20.

When x = 0, the value of f(x) is -20. Thus, f(0) = 0^3 + b(0)^2 + c(0) + d = d = -20.

Now, we have a system of three equations:

-1 + b - c + d = -5 ...(1)

-27 + 9b - 3c + d = 1 ...(2)

d = -20 ...(3)

From equation (3), we find that d = -20. Substituting this value into equations (1) and (2), we get:

-1 + b - c - 20 = -5 => b - c = -16 ...(4)

-27 + 9b - 3c - 20 = 1 => 9b - 3c = 48 ...(5)

Simplifying equations (4) and (5), we can express b and c in terms of a variable, let's say t:

b = -16 + t

c = t/3

Therefore, the values of b, c, and d that satisfy the given conditions are:

b = -16 + t

c = t/3

d = -20

Here, t can take any real value, as it represents a parameter that allows for various solutions.

c) Jacob does not have to contribute to the UIF

A percentage is a representation of a ratio of numbers or proportion of a quantity expressed as a fraction of 100.

The number of days Jacob works per week for Mr Nkosi at his playschool for pre-school = Three days per week

The amount

The amount Jacob is paid per day = R200

Amount Mr Nkosi paid to the UIF for one year in advance regarding Jacob = R624

a) Jacob's gross salary in a year = 52 × 3 × R200 = R31,200

b) The percentage R624 is of Jacob's gross salary = (R624/R31,200) × 100 = 2%

The appropriate methods for analyzing the variables Birth Rate and Death Rate at the same time would be scatterplot, two-way table, and stacked bar chart.

Scatterplot: A scatterplot can be used to visually display the relationship between two quantitative variables, such as Birth Rate and Death Rate. Each point on the scatterplot represents a pair of values for the two variables, making it easy to identify patterns or trends in the data.

Two-way table: A two-way table can be used to display the distribution of two categorical variables, such as Birth Rate and Death Rate, and how they relate to each other. It can help identify the joint frequency or relative frequency of different categories.

Stacked bar chart: A stacked bar chart can be used to show how two categorical variables, such as Birth Rate and Death Rate, are related to each other. Each bar represents the total frequency for each category, and the bars are divided into sections representing the subcategories of the other variable. This makes it easy to compare the distribution of the two variables across each category.

The equation of function g(x) is g(x) = 2(x -7)² - 1, and the values of h and k are 7 and -1, respectively

The function is given as:

f(x) = 2x² - 1

When the function is translated 7 units left, the transformation rule is:

(x,y) -> (x + 7, y)

So, we have:

g(x) = 2(x -7)² - 1

The union of F and F will be:

Step-by-step explanation:

Let

F =  {xlx is a whole number less than 10}

so

F = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

G = {0, 5, 10}

The union of F and G contains all elements that are in F or in G (or possibly both).

The union is symbolically represented by a symbol '∪'.

Thus, the union of F and F will be:

F = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

G = {0, 5, 10}

FUG = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Answer:

The numbers 4 and 16 represent the values of p at which Emilia's monthly profit would be zero. In other words, if Emilia charges $4 or $16 for each loaf, her monthly profit would break even, meaning she would neither make a profit nor incur a loss.

Step-by-step explanation:

In the factored form -15(P - 4)(P - 16), the numbers 4 and 16 represent the values of p at which the monthly profit becomes zero. These values are known as the profit-maximizing points or the roots of the expression.

Setting the expression -15(P - 4)(P - 16) equal to zero and solving for P, we find:

P - 4 = 0 --> P = 4

P - 16 = 0 --> P = 16

Therefore, the numbers 4 and 16 represent the values of p at which Emilia's monthly profit would be zero. In other words, if Emilia charges $4 or $16 for each loaf, her monthly profit would break even, meaning she would neither make a profit nor incur a loss.

These values serve as important points for Emilia to consider when setting the price of her loaves, as charging below $4 or above $16 would result in a negative profit.
