For a line perpendicular to y = - 5 x - 2 and passing through the point ( 10 , 5 ), the equation in slope-intercept form is y = (1/5)x + 3.

To write an equation for a line perpendicular to y = -5x - 2 and passing through the point (10, 5), we first need to find the slope of the new line. The slope of a line perpendicular to another line is the negative reciprocal of the original line's slope. The slope of the original line is -5, so the slope of the new line is 1/5.

Next, we can use the point-slope form of an equation to write the equation for the new line. The point-slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Plugging in the values we have, we get:

y - 5 = (1/5)(x - 10)

Finally, we can rearrange this equation to put it in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. To do this, we'll distribute the 1/5 and then add 5 to both sides of the equation:

y - 5 = (1/5)x - 2
y = (1/5)x + 3

So the equation for the new line is y = (1/5)x + 3. This is our final answer.

Pythagorean Theorem is a mathematical formula that states that the square of the hypotenuse (the side opposite the right angle) of a right triangle is equal to the sum of the squares of the other two sides. It is expressed as a2 + b2 = c2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

The given diagram is a right triangle with two of its sides labeled in inches. To find the length of the third side (d), one must use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, d is the hypotenuse, so d2 = a2 + b2. Therefore, substituting in the given values for a and b, we can solve for d and find that it is approximately 9.48 inches.

The number of child tickets were sold that day are 73.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Cost of child admission= $5.30

Cost of adult admission= $8.70

Now,

Let's assume that "c" represents the number of child tickets sold, and "a" represents the number of adult tickets sold. We can create two equations based on the given information:

c + a = 163 (equation 1: the total number of tickets sold)

5.30c + 8.70a = 1169.90 (equation 2: the total sales)

We can use equation 1 to solve for "a" in terms of "c":

a = 163 - c

Substituting this expression for "a" into equation 2, we get:

5.30c + 8.70(163 - c) = 1169.90

Simplifying and solving for "c", we get:

5.30c + 1418.10 - 8.70c = 1169.90

-3.4c = -248.20

c = 73

Therefore, by algebra the answer will be 73.

The exact value of the remaining trigonometric functions of \( \theta \) are \( \sin \theta = \frac{7\sqrt{52}}{52} \), \( \cos \theta = \frac{-\sqrt{3}\sqrt{52}}{52} \), \( \tan \theta = \frac{-7\sqrt{3}}{3} \), \( \sec \theta = \frac{-\sqrt{52}\sqrt{3}}{3} \), and \( \csc \theta = \frac{\sqrt{52}}{7} \).

We can find the exact value of the remaining trigonometric functions of \( \theta \) by using the Pythagorean identity and the definition of the trigonometric functions. The Pythagorean identity states that \( \sin^2 \theta + \cos^2 \theta = 1 \). The definition of the trigonometric functions are \( \sin \theta = \frac{y}{r} \), \( \cos \theta = \frac{x}{r} \), \( \tan \theta = \frac{y}{x} \), \( \cot \theta = \frac{x}{y} \), \( \sec \theta = \frac{r}{x} \), and \( \csc \theta = \frac{r}{y} \).

Given that \( \cot \theta=-\frac{\sqrt{3}}{7} \), we can use the definition of the cotangent function to find the values of x and y. Let x = -\( \sqrt{3} \) and y = 7. Then, we can use the Pythagorean identity to find the value of r.

\( \sin^2 \theta + \cos^2 \theta = 1 \)

\( \frac{y^2}{r^2} + \frac{x^2}{r^2} = 1 \)

\( \frac{7^2}{r^2} + \frac{(-\sqrt{3})^2}{r^2} = 1 \)

\( \frac{49 + 3}{r^2} = 1 \)

\( \frac{52}{r^2} = 1 \)

\( r^2 = 52 \)

\( r = \sqrt{52} \)

Now, we can use the definition of the trigonometric functions to find the exact value of the remaining trigonometric functions of \( \theta \).

\( \sin \theta = \frac{y}{r} = \frac{7}{\sqrt{52}} = \frac{7\sqrt{52}}{52} \)

\( \cos \theta = \frac{x}{r} = \frac{-\sqrt{3}}{\sqrt{52}} = \frac{-\sqrt{3}\sqrt{52}}{52} \)

\( \tan \theta = \frac{y}{x} = \frac{7}{-\sqrt{3}} = \frac{-7\sqrt{3}}{3} \)

\( \sec \theta = \frac{r}{x} = \frac{\sqrt{52}}{-\sqrt{3}} = \frac{-\sqrt{52}\sqrt{3}}{3} \)

\( \csc \theta = \frac{r}{y} = \frac{\sqrt{52}}{7} = \frac{\sqrt{52}}{7} \)

Therefore, the exact value of the remaining trigonometric functions of \( \theta \) are \( \sin \theta = \frac{7\sqrt{52}}{52} \), \( \cos \theta = \frac{-\sqrt{3}\sqrt{52}}{52} \), \( \tan \theta = \frac{-7\sqrt{3}}{3} \), \( \sec \theta = \frac{-\sqrt{52}\sqrt{3}}{3} \), and \( \csc \theta = \frac{\sqrt{52}}{7} \).

Tracy's expression makes it easier to see how the areas of the rectangles are related i.e. 1/6 bh.

What is a Rectangle?

The opposite sides of a quadrilateral are equal and parallel, and all the angles are equal. Around us, there are several rectangle-shaped items. Two dimensions, the length and breadth, define each rectangle shape. The width and length of a rectangle are its longer and shorter sides, respectively.

Dimensions of top rectangle :

base = b

height = h

So, area = b × h

Dimensions of bottom rectangle :

base = b/3

height = h/2

So, area = b/3 × h/2 = (b × h) 6

Hence, area of bottom rectangle is  1/6th of that top rectangle.

Devin writes the area of the smaller rectangle as the product 1/3 b • 1/2 h. Tracy rewrites this as 1/6 bh.

When sample size is small and population S.D. is unknown, values on the Z row on the table (or Z values) can't be used (note that Z is normal distribution). The correct option is A, i only.

A small sample is a dataset that contains few observations, making it more difficult to generalize the outcomes to the broader population. When a sample size is small, the sample mean, standard deviation, and other statistical measures may be influenced by chance variations.

Larger samples may be required to represent the overall population precisely. The larger the sample size, the closer the sample mean is likely to be to the true population mean. Additionally, when the sample is large, the sample standard deviation is more likely to be an accurate estimate of the population standard deviation.

A standard normal distribution can be used to find out the probability of obtaining a score in a particular range for a normal distribution. The Z value, or the value on the standard normal distribution, is used to convert any regular distribution to a standard normal distribution, which has a mean of 0 and a standard deviation of 1. However, when the sample size is small and the population standard deviation is unknown, the values on the Z row on the table (or Z values) can't be used.

(i)  If Jane's assumption is correct, she will not get 15 tomatoes.

(ii) If Jane's supposition about the body mass of the each tomato is wrong, she could not obtain 15 tomatoes to 1 kg of tomatoes.

What types of things are assumptions?

An presumption is something you believe to be true despite the lack of evidence. People might presume, for instance, that you are a geek if you wear spectacles, even though that is untrue.

(b) (i) If Jane's assumption is correct, then the weight of 15 tomatoes would be:

15 tomatoes × 75 g/tomato = 1125 g

Since 1 kg is equal to 1000 g, Jane would need to buy at least:

1125 g / 1000 g/kg = 1.125 kg of tomatoes

Therefore, Jane would need to ask for at least 1.125 kg of tomatoes to get 15 tomatoes if her assumption about the weight of each tomato is correct.

(b) (ii) If Jane's assumption about the weight of each tomato is not correct, it is possible that she could get 15 tomatoes with 1 kg of tomatoes, depending on the actual weight of each tomato.

For example, if each tomato actually weighs 67 g, then 15 tomatoes would weigh:

15 tomatoes × 67 g/tomato = 1005 g

This is less than 1 kg, so Jane would get 15 tomatoes with 1 kg of tomatoes.

On the other hand, if each tomato actually weighs 100 g, then 15 tomatoes would weigh:

15 tomatoes × 100 g/tomato = 1500 g

This is more than 1 kg, so Jane would not get 15 tomatoes with 1 kg of tomatoes if her assumption about the weight of each tomato is incorrect.

The median of the solutions to the equation 3x³ + 5x² − 6x − 10 = 0 is -√2. The correct answer is A.

To find the median of the solutions to the equation 3x³ + 5x² − 6x − 10 = 0, first find the solutions of the equation and then find the middle value of those solutions.

Group the terms and factor out (3x + 5).

(3x³ + 5x²) + (-6x − 10) = 0

(3x + 5)(x²) + (3x + 5)(-2) = 0

(3x + 5)(x² - 2) = 0

Factor (x² - 2).

(3x + 5)(x + √2)(x - √2) = 0

So the solutions of the equation are x = -5/3, x = -√2, and x = √2.

To find the median of these solutions, we need to order them from least to greatest:

The estimated value of the standard deviation using the range rule of thumb is 0.875 degrees F

The range rule of thumb is used to estimate the standard deviation of a data set using the range of the data. In this case, the range of the data is 3.5 degrees F. Using the range rule of thumb, the standard deviation of the data can be estimated by taking the range (3.5) and dividing it by 4, which gives us an estimated standard deviation of 0.875 degrees F.

This estimated value is within 0.2 degrees F of the actual standard deviation of the data (0.72 degrees F).

To compare this result to the actual standard deviation of the data, we subtract the estimated value from the actual value and take the absolute value of the result. This gives us the difference between the two values:

|0.72 - 0.875| = 0.155

Since the difference between the estimated and actual standard deviations is less than 0.2 degrees F, we can say that the range rule of thumb provides a reasonable approximation of the standard deviation for this data set.

In conclusion, the estimated value of the standard deviation using the range rule of thumb is 0.875 degrees F, and this value is within 0.2 degrees F of the actual standard deviation of 0.72 degrees F.

The function y=10x(x+1) is already in factored form, with a=10, r=0, and s=-1.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is termed the domain of the function and the set Y is called the codomain of the function. Initially, functions represented the idealized relationship between varied quantities and other variables.

To see this, we can rewrite the function as f(x)=10(x-0)(x-(-1)), which matches the form f(x)=a(x-r)(x-s). Therefore, the values of a, r, and s are:

a = 10
