Step-by-step explanation:

Hypothesis tests carried out on contingency tables are based on the chi-square, a statistic.

The contingency table is a Frequency tables of two variables presented at the same time. These tables are constructed when we represent all the levels of a variable as rows in a table and represent the other variables as columns, after which we find the joint or cell frequency for every of the cell.

I know this isn’t a math problem but it is a serious question about math.

Would Practical math be easier than pre-Calc/trigonometry?

I looked up what practical math was and it seems to be like real-world problems and really long equations, and that is something I struggle with the most because I end up lost a confused but is it as bad as it sounds??? And if it is that bad is it better than pre-calc/trigonometry.

Answers

Answer:

I live in Ireland and I take on additional maths as part of my course (extra maths). In my course we do a mix of pre calc and practical. Personally I find them both okay but I think practical math would get quite hard and boring if you dont like it. If u already find it boring, it's probably going to be harder to understand and like. I would recommend doing pre calc as u still do some equations but it's a good mix. it's totally up to u tho good luck! ♡

3 sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sisters age. what is the age of the youngest child.

Answers

Step-by-step explanation:

Let n be the age of the youngest sister. Since the ages are consecutive odd integers, the next sister's age is n+2, and the oldest sister is n+4. the following equation represents the relationship between the girls' ages.

n + 3(n + 4) = 5(n + 2) - 5

n + 3n + 12 = 5n + 10 - 5

4n + 12 = 5n +5

-4n  -5      -4n -5

7 = n

so the sisters are 7, 9, and 11

The age of the youngest child 7 years.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Since, the ages are consecutive odd integers,

So, Let x be the age of the youngest sister.  

The next sister's age is x + 2,

And, the oldest sister is x + 4.

Hence, The following equation represents the relationship between the girls ages.

x + 3(x + 4) = 5(x + 2) - 5

x + 3x + 12 = 5x + 10 - 5

4x + 12 = 5x + 5

12 - 5 = 5x - 4x

x = 7

So, The age of the youngest child 7 years.

Each of the points $A, B, C, D, E,$ and $F$ in the figure below represents a different digit from 1 to 6. Each of the five lines shown passes through some of these points. The digits along each line are added to produce five sums, one for each line. The total of the five sums is 47. What is the digit represented by $B$ ?

Answers

Answer:

(E) 5

Step-by-step explanation:

Refer to picture

Calculating sums, we get a result of:

2A + 3B + 2C + 2D + 2E + 2E = B + 2(sum of all digits) = 47

Sum of all digits is:

1 + 2 + 3 +4 + 5 + 6 = 1/2*6*(1 + 6) = 21

Considering this in the equation above, we get:

B + 2*21 = 47B = 47 - 42B = 5

Correct answer is (E) 5

m and n are negative rational numbers. The product will be negative
TRUE or FALSE

Answers

Answer:

The product of two negative rational numbers can not be negative. Hence, the statement that 'the product will be negative' is FALSE.

Step-by-step explanation:

We know that a rational number is a number that can be written in the form p/q, where p and q are integers.

A negative rational number is a number that can be represented as -p/q or

(-1) p/q, where p and q are whole numbers.

It must be not that the product of two negative rational numbers would always be positive.

For example, let suppose m = -5 and n = -7 are two negative rational numbers.

Taking the product of  -5 and -7.

= (-5) × (-7)

= 35

Therefore, the product of two negative rational numbers can not be negative. Hence, the statement that 'the product will be negative' is FALSE.

Answer:

[tex]\frac{5}{6}[/tex]x-10

Step-by-step explanation:

([tex]\frac{1}{3}[/tex]x-8)+([tex]\frac{1}{2}[/tex]x-2) = [tex]\frac{1}{3}[/tex]x-8+[tex]\frac{1}{2}[/tex]x-2

[tex]\frac{1}{3}[/tex]x-8+[tex]\frac{1}{2}[/tex]x-2 = [tex]\frac{1}{3}[/tex]x+[tex]\frac{1}{2}[/tex]x-10

If you -8 then -2, you are subtracting 10 from the equation in total.

[tex]\frac{1}{3}[/tex]x+[tex]\frac{1}{2}[/tex]x-10 = [tex]\frac{2}{6}[/tex]x+[tex]\frac{3}{6}[/tex]x-10

To make the denominator the same, I will multiply the first fraction by 2 and the second fraction by 3 so that their denominators are 6.

[tex]\frac{2}{6}[/tex]x+[tex]\frac{3}{6}[/tex]x-10 = [tex]\frac{5}{6}[/tex]x-10

Once the denominators are the same, you can do the working for the numerators directly (2+3=5) and keep the denominator the same.

What does the value 8,795 represent in this situation?
Options: each day,the total cost decreases by $8795 or each day the total cost increases by 8795 or the initial cost is 8795 or the total cost to produce a part for d days is 8795...plz help

Answers

Answer:

Hi,

The equation of a linear function has the following format:

[tex]y = mx + b[/tex]

Where  represents the value of   for when   is equal to zero.

Therefore, 8795 can be considered the initial value for production.

Step-by-step explanation:

The graph of a linear function is the same as the example below:

As noted in the figure, the value of [tex]b[/tex] provides the value of [tex]y[/tex] when [tex]x[/tex] is null. This is also called the linear coefficient of the line (or intercept)

The value of [tex]m[/tex]  represents the rate of change of the function and is linked to the slope of the line.

Any questions just ask in the comments.

Since the equation given is f(d) = 325d +8,795, the value that 8,795 represent in this situation is the initial cost.

The given equation in this case is f(d) = 325d +8,795, it should be noted that 8795 is the fixed cost. On the other hand, the expression 325d represents the variable cost.

325d means that the cost will increase each day by that amount. Therefore, the value that 8,795 represents in this situation is the initial cost.

Give an example of a function F(x) that is an antiderivative of f(x) = 9 cos(9x)+ 3x^2

Answers

We are integrating f(x) = 9cos(9x) + 3x²:    [tex]\int\ {9cos(9x)+3x^{2} } \, dx[/tex]

a) Apply the sum rule

[tex]\int\9cos(9x)} \, dx +\int\ 3x^{2} } \, dx[/tex]

b) Calculate each antiderivative

First integral

[tex]\int\ {9cos(9x)} \, dx[/tex]

1. Take out the constant

[tex]9\int\ {cos(9x)} \, dx[/tex]

2. Apply u-substitution, where u is 9x

[tex]9\int\ {cos(u)\frac{1}{9} } du[/tex]

3. Take out the constant (again)

[tex]9*\frac{1}{9} \int{cos(u)} du[/tex]

4. Take the common integral of cos, which is sin

[tex]9*\frac{1}{9}sin(u)}[/tex]

5. Substitute the original function back in for u and simplify[tex]9*\frac{1}{9} sin(9x) = sin(9x)[/tex]

6. Always remember to add an arbitrary constant, C, at the end

[tex]sin(9x) + C[/tex]

Second integral

[tex]\int3x^{2} } \, dx[/tex]

1. Take out the constant

[tex]3\int{x^{2} } \, dx[/tex]

2. Apply the power rule, [tex]\int{x}^{a} \, dx =\frac{x^{a+1} }{a+1}[/tex], where a is your exponent

⇒ [tex]3*\frac{x^{2+1} }{2+1} = x^{3}[/tex]

3. Add the arbitrary constant

[tex]x^{3} + C[/tex]

c) Add the integrals

sin(9x) + C + x³ + C = sin(9x) + x³ + C

Notice the two arbitrary constants.  Since we do not know what either constant is, we can combine them into one arbitrary constant.

Answer:

F(x) = sin(9x) + x³ + C

Answer:

[tex]g(x)=sin(9x)+x^3+C[/tex], choose a constant that is any number you want for C

Step-by-step explanation:

So we have a function,  [tex]f(x)=9cos(9x)+3x^2[/tex]  An antiderivative is also called an integral, so to find the antiderivative of f(x) we find the integralso we will say g(x) is equal to the integral (antiderivative) of f(x)Then [tex]g(x)=\int\ {(9cos(9x)+3x^{2}) } \, dx[/tex] Which can be written as [tex]g(x)=\int\ {9cos(9x)} \, dx +\int\ {3x^{2} } \, dx[/tex] So let's do the first part integral [tex]\int\ {9cos(9x)} \, dx[/tex] which can be written as [tex]9*\int\ {cos(9x)} \, dx[/tex] Then we use u substitution integration, and [tex]u=9x,\frac{du}{dx} =9,dx=\frac{1}{9}*du[/tex] so we replace dx and 9x so that [tex]9*\int\ {cos(9x)} \, dx =9*\int\ {\frac{1}{9}cos(u) } \, du=9*\frac{1}{9}*\int\ {cos(u)} \, du[/tex] Leaving [tex]\int\ {cos(u)} \, du=sin(u)+C[/tex] then replace u with 9x, so [tex]sin(9x)+C[/tex]Now for the second part integration[tex]\int\ {3x^2} \, dx =3 *\int\ {x^2} \, dx=3*\frac{x^{2+1}}{2+1}+C=3*\frac{x^{3}}{3}+C=x^3+C[/tex] so [tex]g(x)=sin(9x)+C+x^3+C=sin(9x)+x^3+C[/tex] so [tex]g(x)=sin(9x)+x^3+C[/tex] is a general solution antiderivative to f(x)

Graph the line that contains the point (-3,1) with a slope of 2/3

Answers

Answer:

The graph of the line that contains the point [tex](-3,1)[/tex] with a slope of 2/3.

Step-by-step explanation:

As the line contains the point (-3, 1) with a slop 2/3

Given the slop-intercept form of the line equation

y = mx+b

Here,

m = slopeb = y-intercept

Substituting the values in the slop-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]1 = \frac{2}{3} (-3) + b[/tex]

[tex]1 =- 2 + b[/tex]

switching sides

[tex]-2+b=1[/tex]

[tex]b=3[/tex]

Now Substituting the value of [tex]b=3[/tex] in the slop-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y=\frac{2}{3} x+3[/tex]

Hence, the line of the equation will be:  [tex]y=\frac{2}{3} x+3[/tex]

Therefore, the graph of the line that contains the point [tex](-3,1)[/tex] with a slope of 2/3.
