The given equation 6x+2y=13 is a linear equation in two variables. In this equation, x and y are variables while 6 and 2 are their respective coefficients, and 13 is a constant term. The equation can be represented as a straight line on a graph. The slope of this line is -3, and it intersects the y-axis at the point (0, 13/2).

In this equation, if we substitute x=0, then y=13/2, and if we substitute y=0, then x=13/6. These are the two points that the line passes through the x and y-axis.

A linear equation is a polynomial equation that is of the first degree, meaning the variables in the equation are not raised to any powers other than one. This equation is in the standard form where the variables are in the first degree. 6x + 2y = 13 is the form of the given linear equation. x and y are the two variables, and 6 and 2 are their respective coefficients. The equation can be represented as a straight line on a graph. The slope-intercept form of this equation is y = -3x + 13/2. The equation is also in standard form.

When x = 0, the equation becomes 2y = 13. This means that the point of intersection is (0, 13/2) when y = 0, the equation becomes 6x = 13, and the point of intersection is (13/6, 0). The slope of the line is -3. When x increases by 1, y decreases by 3.

The correct option is the second one, the value of x is 8.

We can see that the two horizontal lines are parallel, thus, the two angles defined are alternate vertical angles.

Then these ones have the same measure, so we can write the linear equation:

11 + 7x = 67

Solving this for x, we will get:

11 + 7x = 67

7x = 67 - 11

7x = 56

you should know the observed frequencies or counts for different categories or levels of the variable you are examining. Therefore, the correct answer is B.

The chi-square test is a statistical test used to determine if there is a significant association between categorical variables. It compares the observed frequencies in each category to the expected frequencies, assuming there is no association or difference between the variables. By comparing the observed and expected frequencies, the test calculates a chi-square statistic, which follows a chi-square distribution.

In order to calculate the expected frequencies, you need to have the frequency distribution of the variables of interest. This means knowing the counts or frequencies for each category or level of the variable. The test then compares the observed frequencies with the expected frequencies to determine if there is a significant difference.

The mean, variance, and other measures of central tendency and dispersion are not directly involved in the chi-square test. Instead, the focus is on comparing observed and expected frequencies to test for associations or differences between categorical variables.

Hope this helps!

Answer:

2, 6, and 7.

Step-by-step explanation:

In a right triangle, the hypotenuse (longest side of the triangle) squared is equal to the sum of the other sides squared.

So for the second triangle, add 36 squared to 15 squared. The result is 1521. Compare that to the hypotenuse (39) squared. The second triangle is a right triangle because the hypotenuse squared is also 1521. I did this with each triangle and the 2nd, 6th, and 7th were right triangles.

P = 64 cm

2(( x + 14) + x) = 64

2x + 28 + 2x = 64

4x + 28 = 64

4x = 64 - 28

4x = 36

x = 36/4

x = 4

The intercepts are (0, 0), (-√5, 0), and (√5, 0). The relative maximum is at (-1, 4), and the relative minimum is at (1, -4). The point of inflection is at (0, 0). There are no asymptotes.

To analyze the function f(x) = \(x^5\) - 5x, we can find intercepts, relative extrema, points of inflection, and asymptotes.

A. Intercepts:

To find the x-intercepts, we set f(x) = 0 and solve for x:

\(x^5\) - 5x = 0

x(\(x^4\) - 5) = 0

x = 0 (x-intercept at the origin)

\(x^4\) - 5 = 0

\(x^4\) = 5

x = ±√5 (two more x-intercepts)

The y-intercept occurs when x = 0:

f(0) = 0^5 - 5(0) = 0

So the y-intercept is (0, 0).

B. Relative Extrema:

To find the critical points, we take the derivative of f(x) and set it equal to zero:

f'(x) = 5\(x^4\) - 5 = 0

5\(x^4\) = 5

\(x^4\) = 1

x = ±1

To determine whether these are relative minima or maxima, we check the second derivative:

f''(x) = 20x³

When x = -1, f''(-1) = 20(-1)³ = -20 < 0, so there is a relative maximum at (x, y) = (-1, 4).

When x = 1, f''(1) = 20(1)³ = 20 > 0, so there is a relative minimum at (x, y) = (1, -4).

C. Point of Inflection:

To find the point(s) of inflection, we set the second derivative equal to zero:

20x³ = 0

x = 0

D. Asymptotes:

The function f(x) = \(x^5\) - 5x does not have any asymptotes.

E. Graphing Utility:

Using a graphing utility, we can plot the function f(x) = \(x^5\) - 5x and verify the results obtained above.

The parameter in this scenario is the mean level of the toxic chemical in tomatoes from a specific producer. The null hypothesis states that the mean level of the chemical is equal to or below the recommended limit of 0.2 ppm, while the alternative hypothesis states that the mean level exceeds the recommended limit.

The parameter being examined is the mean level of the toxic chemical in tomatoes obtained from a specific producer. The consumer health group wants to determine whether the mean level of the chemical in these tomatoes exceeds the recommended limit of 0.2 ppm.

The null hypothesis (H0) states that the mean level of the chemical in tomatoes from this producer is equal to or below the recommended limit: μ ≤ 0.2 ppm.

The alternative hypothesis (Ha) states that the mean level of the chemical in tomatoes from this producer exceeds the recommended limit: μ > 0.2 ppm.

In other words, the null hypothesis assumes that the tomatoes do not have a significantly higher mean level of the toxic chemical, while the alternative hypothesis suggests that there is evidence to support a higher mean level.

By conducting appropriate statistical tests on the sample data, the consumer health group can make conclusions about whether the mean level of the toxic chemical in tomatoes from this producer exceeds the recommended limit of 0.2 ppm.

Answer:

70 inches

Step-by-step explanation:

the width of the original rectangle:

48/2 - 13 = 24 - 13 = 11

the new rectangle:

length: 13

width: 2(11) = 22

perimeter: 2(13+22) = 2(35) = 70

The perimeter of the new rectangle is 70 inches.

The area of Rectangle is length times of width.

The perimeter of a rectangle is given by the formula P = 2(l + w)

where P is the perimeter, l is the length, and w is the width.

The first rectangle has a perimeter of 48 inches and a length of 13 inches.

48 = 2(13 + w)

24 = 13 + w

w = 11

So the first rectangle has a length of 13 inches and a width of 11 inches.

The second rectangle has the same length of 13 inches and twice the width of the first rectangle, which means it has a width of 22 inches.

P = 2(13 + 22)

= 2(35)

= 70

Therefore, the perimeter of the new rectangle is 70 inches.

Answer:

C) y = 16 feet

Step-by-step explanation:

the corresponding sides in ABCD are equal to their corresponding sides by EFGH multiplied by something

all values are in feet

let x represent the unknown side in ABCD

ABCD lengths in order: x, 30 , 40 , 60

let a and b represent the unknown sides in EFGH

EFGH lengths in order: 6, 12, a, b

thus, 30 corresponds to 12 as they are both the second shortest sides

corresponding side in EFGH * something = corresponding side in ABCD

12 * something = 30

let something be r

12 * r = 30

divide both sides by 12 to isolate r

r = 30/12

thus, to get a side in ABCD, we multiply the corresponding side in EFGH by 30/12

we want to find the second longest side in EFGH. the corresponding side to that in ABCD is 40, as 40 is the second longest side in ABCD

let the second longest side in EFGH = y

y * 30/12 = 40

multiply both sides by 12/30 to isolate y

40 * 12 / 30 = y = 16

y = 16 feet

The person who filled out the deposit slip received $88.79 in cash. The correct answer is option c.

To find out how much cash the person who filled out the deposit slip received, we need to fill in the missing amounts on the slip.

First, we need to calculate the subtotal by adding the amounts of the checks and cash:

Subtotal = 15.00 + 62.44 + 27.83 + 45.75

Subtotal = 151.02

Next, we need to determine the amount of cash received by subtracting the subtotal from the total:

Total = Subtotal - cash received

62.23 = 151.02 - cash received

To solve for cash received, we can subtract the total from the subtotal:

Cash received = Subtotal - total

Cash received = 151.02 - 62.23

Cash received = 88.79

The height of ladder is 10.0374 feet  closest to 10 feet.

The relationship between the sides of a right-angled triangle is explained by the Pythagoras Theorem, which is also known as the Pythagorean Theorem. This is an important mathematical concept. Pythagorean triples are another name for the sides of the right triangle. With examples, this theorem's formula and proof are explained.

The Pythagoras theorem is mostly used to find the angle of a triangle and the length of an unknown side. We can get the base, perpendicular, and hypotenuse formulas from this theorem.

Given length of ladder = 11 feet

distance from supporting wall = 4.5 feet

to find height

since wall will be perpendicular from base we can use  Pythagoras theorem

hy² = p² + b²

where hy = hypotenuse, p = perpendicular  = h and b = base

hy = 11 feet, b = 4.5 feet

11² = 4.5² + h²

h² = 121 - 20.25

h = √100.75

h = 10.0374 feet
