Step-by-step explanation:

the graphic shows us - the 2 end points are :

(-4, -4) and (4, -1)

the distance between these 2 points (= length of the line segment) is calculated via Pythagoras for right-angled triangles.

c² = a² + b²

c is the Hypotenuse and the distance between the 2 points. a and b are the legs of the triangle enclosing the 90 degree angle, as they are the differences between the x and the y coordinates of the points.

so,

distance² = (-4 - 4)² + (-4 - -1)² = (-8)² + (-3)² = 64 + 9 = 73

distance = sqrt(73) = length of line segment.

Step-by-step explanation:

\(\boxed{\begin{minipage}{5 cm}\underline{General equation of an ellipse}\\\\$\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1$\\\end{minipage}}\)

Given equation:

\(2(x+4)^2+3(y-1)^2=24\)

To write the equation of the ellipse in standard form, divide both sides by 24 so that the right side of the equation is equal to one:

\(\implies \dfrac{2(x+4)^2}{24}+\dfrac{3(y-1)^2}{24}=\dfrac{24}{24}\)

\(\implies \dfrac{(x+4)^2}{12}+\dfrac{(y-1)^2}{8}=1\)

Therefore:

The center of the ellipse is (h, k).

Therefore, the coordinates of the center are (-4, 1).

As a > b, the ellipse is horizontal, so 2a is the major axis and 2b is the minor axis.  Therefore:

The focal radius is the distance from a point on the ellipse to a focus.

The sum of the focal radii is equal to the length of the major axis.

Therefore, the sum of the focal radii is 4√3.

As a > b, the coordinates of the foci are (h±c, k).

As c² = a² - b², first find the value of c:

\(\implies c^2=12-8\)

\(\implies c=\sqrt{4}=2\)

Therefore, the coordinates of the foci are:

As a > b, the coordinates of the vertices are (h±a, k):

and the coordinates of the co-vertices are (h, k±b):

The eccentricity of the ellipse is:

\(\implies e=\dfrac{c}{a}=\dfrac{2}{2\sqrt{3}}=\dfrac{\sqrt{3}}{3}\)

The ratio of  a: b is = 5:7

Here the ratio is a:b

When the prices are both decreased by £10, the new ratio

= a-10 : b-10

When the prices are both increased by  £5, the new ratio

= a+5 : b+5

By the given conditions,

a-10 : b-10 = 3:5

or, \(\frac{a-10}{b-10\\}\) =\(\frac{3}{5}\)

or, 5(a-10) = 3(b-10)

or, 5a -50 = 3b-30

or, 5a -3b = 20 .... ...(1)

and a+5 : b+5 =3 : 4

or,\(\frac{a+5}{b+5}\) = \(\frac{3}{4}\)

or, 4(a+5) = 3(b+5)

or, 4a +20 = 3b+15

or, 4a-3b= -5 .... ...(2)

subtract the equation(2) from equation(1)

   5a -3b - (4a -3b) =20 - (-5)

or, 5a-3b-4a+3b = 20+5

or, 5a-4a = 25

Therefore,  a =25

Putting a=25 in equation (1), we get

 125-3b=20

or, 3b= 105

therefore, b=35

a :b =25:35

       = 5:7

Hence, the ratio of  a: b = 5:7

No, the presence of an effect does not necessarily imply that error variance will go away.

The presence of an effect does not necessarily imply that error variance will go away. In fact, error variance is an inherent part of any statistical model and represents the amount of variation in the response variable that is not explained by the predictor variables.

Even if a predictor variable has a significant effect on the response variable, there may still be some unexplained variation in the response that is attributable to error variance.

It is important to take into account and control for error variance in any statistical analysis, as it can affect the precision and accuracy of the estimates of the model parameters and can also influence the interpretation of the results.

One way to control for error variance is to use appropriate statistical methods, such as analysis of variance (ANOVA), regression analysis, or other modeling techniques that take into account the variability in the data.

The ordered pair that is a solution of the system of inequalities:

4x + 2y > 8

x - y ≥ 2

is (7, 2)

Here we have the following system of inequalities:

4x + 2y > 8

x - y ≥ 2

The points (x, y) are solutions only if make both inequalities true. For example let's use the first pair (2, 4)

Replacing that in the inequalities we get:

4*2 + 2*4 > 8

2 - 4 ≥ 2

Simplify the left side:

16 > 8

-2  ≥ 2

The second inequality is false, so (2, 4) is not a solution.

The correct option is the second one, (7, 2), evaluating the inequalities we get:

4*7 + 2*2 = (32) > 8

7 - 2 = 5 ≥ 2

The possible names for the shape in the image are Parallelogram and Quadrilateral since it has two equal opposite sides which are parallel.

First we take a look of the properties of the likely names;

Properties of Parallelograms

Properties of Quadrilaterals

Properties of Rectangles

Properties of Rhombus

Properties of Trapezoids

From the properties, the shape is not a rectangle because each of the interior angle is not 90 degrees. It is not a Rhombus because all its sides are not equal. It is not a Trapezoid because only the bases are parallel to each each other.

Hence, the possible names for the shape in the image are Parallelogram and Quadrilateral since it has two equal opposite sides which are parallel.

The lowest measurement scale the researcher could use to measure the differences in consumer feelings about the perceived reliability of the products is the ordinal scale.

In order to compare and rank consumer feelings about the perceived reliability of different products, the researcher needs a measurement scale that allows for a relative ordering of the responses. The ordinal scale is the lowest level of measurement that provides this capability.

An ordinal scale assigns numbers or labels to observations in a way that reflects their relative position or ranking.

It allows for comparisons of the responses in terms of greater or lesser, but it does not provide information about the magnitude of the differences between the rankings. In other words, it indicates the order of preference or strength of feeling but does not quantify the exact differences.

Using an ordinal scale, the researcher can ask consumers to rate the products on a scale such as "strongly disagree," "disagree," "neutral," "agree," and "strongly agree" in terms of their perceived reliability. Based on the responses, the researcher can determine the relative strength of feelings about each product's reliability by comparing the rankings.

While the ordinal scale provides valuable insights into the relative ordering of consumer preferences, it does not allow for precise measurements or calculations of mean differences between products. For more detailed analysis, higher-level measurement scales such as interval or ratio scales would be required.

The decimal representation of \($\frac{n}{475}$\)terminates for one value of n between 1 and 474 inclusive:\($n=475$\). This is because \($475$\) is the only number between 1 and 474 that is divisible by 475.

To determine for how many integer values of n between 1 and 474 inclusive does the decimal representation of\($\frac{n}{475}$\) terminate, we must find out which values of n between 1 and 474 are divisible by 475. We can do this by dividing each number between 1 and 474 by 475 and checking if the remainder is 0. If the remainder is 0, then the number is divisible by 475 and the decimal representation of

\($\frac{n}{475}$\)

will terminate. We find that the only number between 1 and 474 that is divisible by 475 is

\($n=475$\),

so the decimal representation of

\($\frac{n}{475}$\)

terminates for only one value of n between 1 and 474 inclusive: \($n=475$.\)

Step-by-step explanation:

because you start on the first doit then go up4 then go across 5 to another dot

The bit pattern 0x0C000000 represents the decimal number 201326592 when interpreted as both a two's complement integer and an unsigned integer.

To determine the decimal representation of the bit pattern 0x0C000000, we need to consider whether it is interpreted as a two's complement integer or an unsigned integer.

If the bit pattern is interpreted as a two's complement integer, we follow these steps:

Check the most significant bit (MSB). If it is 0, the number is positive; if it is 1, the number is negative.

In this case, the MSB of the bit pattern 0x0C000000 is 0, indicating a positive number.

Convert the remaining bits to decimal using the positional value of each bit. Treat the MSB as the sign bit (0 for positive, 1 for negative).

Converting the remaining bits, 0x0C000000, to decimal gives us 201326592.

Therefore, if the bit pattern 0x0C000000 is interpreted as a two's complement integer, it represents the decimal number 201326592.

If the bit pattern is interpreted as an unsigned integer, we simply convert the entire bit pattern to decimal.

Converting the bit pattern 0x0C000000 to decimal gives us 201326592.

Therefore, if the bit pattern 0x0C000000 is interpreted as an unsigned integer, it represents the decimal number 201326592.

Step-by-step explanation:

One ounce (oz) and milliliter (ml) are different units of measurement

An ounce (oz) is a unit of weight that is commonly used in the United States, while a milliliter (ml) is a unit of volume that is commonly used in the metric system. One ounce is equal to approximately 28.35 grams, while one milliliter is equal to one cubic centimeter.

So, 1 oz is not the same as 15 ml, because oz is a unit of weight and ml is a unit of volume. 1 oz is roughly equal to 28.35 grams and 15 ml is equal to 15 cubic centimeters. These measurements are not equal to each other and it's not possible to convert them directly.

In summary, that are used to measure different things. 1 oz is not the same as 15 ml, because oz is a unit of weight and ml is a unit of volume.It's important to remember that when cooking or measuring ingredients, it is important to use the appropriate unit of measurement for the task at hand.
