The point- slope form of the line is y-5 = -0.25(x+6).

What is line?

A line is an one-dimensional figure. It has length but no width. A line can be made of a set of points which is extended in opposite directions to infinity. There are straight line, horizontal, vertical lines or may be parallel lines perpendicular lines etc.

A line with a slope of –1/4 passes through the point (–6,5)

Any line in point - slope form can be written as

y - y₁= m(x -x₁) -------(1)

where,

y= y coordinate of second point

y₁ = y coordinate of first point

m= slope of the line

x= x coordinate of second point

x₁ = x coordinate of first point

In the given problem (x₁ , y₁) = (-6,5) and m= -1/4

Putting all these values in equation (1) we get,

y-5= (-1/4) (x- (-6))

⇒ y-5 = -0.25(x+6)

Hence, the point- slope form of the line is y-5 = -0.25(x+6).

The upward unit normal to the surface 7cos(xy) = \(e^(^8^z^)\)- 13 at (7, π, 0) is (0, 0, 1/√2).

To find the upward unit normal to the surface, we need to calculate the partial derivatives of the given surface equation with respect to x, y, and z.

Starting with the given equation: 7cos(xy) = \(e^(^8^z^)\)- 13, we differentiate it partially with respect to x, y, and z.

Evaluating these partial derivatives at the point (7, π, 0), we have:

Next, we construct the normal vector by normalizing the vector (0, 0, 8) to obtain the unit normal vector: (0, 0, 1).

Therefore, the upward unit normal to the surface at (7, π, 0) is (0, 0, 1).

Step-by-step explanation:

The "d" format specifier is used to denote a signed decimal integer in various programming languages and formatting systems.

When used in format strings or printf-style functions, the "d" specifier indicates that the corresponding argument should be formatted as a signed decimal integer. It allows for the representation of both positive and negative whole numbers, including zero.

For example, in C programming, the printf function can be used with the "%d" format specifier to display a signed decimal integer value. Similarly, in other languages such as Python, the "{:d}" format specifier can be used with the format() function or string interpolation to represent a signed decimal integer.

Using the "d" specifier ensures that the output is formatted as a base-10 representation of a signed integer, taking into account the sign of the number.

The sum of measures of all the interior angles in the polygon having 30 sides​ is 5040°.

A polygon is a closed polygonal chain made up of a finite number of straight-line segments and is a type of planar figure in geometry. The interior and exterior angles of regular and irregular polygons are related by polygonal angles.

The angles found inside a polygon with two sides are called interior angles. By deducting 2 from the total number of sides and multiplying by 180°, we may find the sum of the interior angles of a polygon.

Sum of Interior Angles = (n-2) × 180°

n = 30

So, the Sum of Interior Angles = (30-2) × 180° = 28 × 180° = 5040°

Thus, the polygon's 30 sides add up to a total interior angle measure of, 5040°.

Answer:

14 plantains

Step-by-step explanation:

Given

\(x \to\) plantain in a pile

\(y \to\) plantain received by each

\(n = 23\) travelers

Required

The least value of y

Note that:

- There are x plantains in 1 pile, so there will be 63x in 63 piles

- The number of plantains shared is: 7 to 63x (7 represents the single plantain)

- 1 traveler gets y plantains, so 23y will receive 7 + 63x plantains

So, the equation is:

\(23y = 7 + 63x\)

Make y the subject

\(y = \frac{7 + 63x}{23}\)

The values of x and y must be integer and these values must be greater than 0.

Using trial by error method, we test the values of x starting from 1;

So, we have:

\(x = 1 \to y = \frac{7 + 63 * 1}{23} = \frac{70}{23} = 3.04\)

\(x = 2 \to y = \frac{7 + 63 * 2}{23} = \frac{133}{23} = 5.78\)

\(x = 3 \to y = \frac{7 + 63 * 3}{23} = \frac{133}{23} = 8.52\)

\(x = 4 \to y = \frac{7 + 63 * 4}{23} = \frac{259}{23} = 11.26\)

\(x = 5 \to y = \frac{7 + 63 * 5}{23} = \frac{322}{23} = 14\)

So, the smallest values of x and y that satisfy the equation is:

\((x,y)=(5,14)\)

Hence, the least number of plantain each traveler got is 14

The probability of getting two students with the same major is higher for liberal arts majors, followed by business majors, engineering majors, and science majors.

To calculate the probability of getting two specific majors when selecting two students at random, we need to know the total number of students in each major. Let's assume there are 100 engineering majors, 150 business majors, 75 science majors, and 200 liberal arts majors.

The probability of selecting an engineering major as the first student is 100/525 (total number of students). The probability of selecting another engineering major as the second student is 99/524 (one less student in the pool). Multiplying these probabilities gives us 0.036 or 3.6% chance of getting two engineering majors.

Similarly, the probability of getting two business majors is (150/525) * (149/524) = 0.082 or 8.2%, two science majors is (75/525) * (74/524) = 0.023 or 2.3%, and two liberal arts majors is (200/525) * (199/524) = 0.151 or 15.1%.

Therefore, the probability of getting two students with the same major is higher for liberal arts majors, followed by business majors, engineering majors, and science majors.

In the following question, Welch's t-test is used to compare the means of two populations with unequal variances. It is a variation of the standard Student's t-test, which is used when the variances are assumed to be equal.

Welch's t-test is generally used when the sample sizes are small and the variances are significantly different.

The distributional assumptions that are needed for Welch's t-test include:

Normality - The data from each population must be normally distributed, although this assumption is not always strictly required for the test to be valid.

Equal variances - The variances of the two populations must be equal. In practice, this assumption is often difficult to satisfy, particularly when the sample sizes are small. Welch's t-test does not require the assumption of equal variances.

Independence - The samples from each population must be independent of each other. This means that the observations in one sample should not be related to the observations in the other sample.

Welch's t-test is a parametric test, which means that it is based on assumptions about the underlying distribution of the data. If the distributional assumptions are not met, then the test may not be valid. In such cases, non-parametric tests may be used instead, such as the Wilcoxon rank-sum test.

The best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

The process of changing the value of one form to another is called conversion. It doesn't affects the value, it simply converts one form to another.

Now it is given that,

Width of a speck of dust = 8.2 x 10⁻⁷ m

Since, 1 kilometer = 1000 meters = 10³ meters

Therefore, 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷ x 10³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷⁺³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁴ kilometer

Thus, the best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

Answer:

$843.67

Step-by-step explanation:

1. Calculate the discount that was taken off from the original price.

$896 x 12% = $107.52

2. Subtract the discount taken off from the original price. This gives you the total paid AFTER the discount was taken.

$896-$107.52= $788.48

3. Calculate the tax amount by multiplying the discount price by the tax rate.

$788.48 x 7% = $55.19

4. Add the tax amount back to the discount price.

$788.48 + $55.19 = $843.67

Answer:

The total distance around the running track is 194.3 m

Step-by-step explanation:

Here, we are interested in calculating the distance around the running track.

We have two semi-circles of diameter 30m and two parallel straight lines of length 50m

Firstly let’s add the parallel straight lines, we have 50 + 50 = 100 m

Now these two semicircles when joined together gives a full circle. And since they are of same diameter, by calculating the circumference of the full circle, we can have the length around the two bends

Mathematically, that would be; πd

The circumference is thus; 22/7 * 30 = 94.29 m

Thus, the length of the running track will be 100 + 94.3m = 194.3m

The length of the rectangle is 7y - 3

What is a Rectangle?

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. The area of  a rectangle A = L×W

Where,

A = Area of the rectangle which is 7y^2 - 3y

L = Length  which is unknown

W = Width of the rectangle which is y

Substituting,

7y^2 - 3y = L × y

divide through by y

(7y^2 - 3y)/y = L

L = 7y - 3

Therefore the length of the rectangle is 7y - 3
