the three of them are similar in size if that makes sense, im not 100% sure but i got a harder question after it so im pretty sure its right.

Using it's concept, it is found that the box-and-whisker plots A, B and D have the same interquartile range of 4.

It shows three things:

The interquartile range is the difference of the third quartile and the first quartile, hence it is the length of the box-and-whisker plot. From this, plots A, B and D have the same interquartile range of 4.

The value of a in y³ - 5y² + 72y - 68 = 0 is -5

A quadratic equation is in the form:

ax² + bx + c = 0

where a, b, c are constants integers.

Given the roots of the equation as 1 and 2 - 8i, hence the third root is 2 + 8i. Complex roots are in conjugate pairs, hence:

y = 1 or y = 2 - 8i or y = 2 + 8i

(y - 1) = 0; y - 2 + 8i = 0 and y - 2 - 8i = 0

(y - 1)(y - 2 + 8i)(y - 2-8i) = 0

y³ - 5y² + 72y - 68 = 0

The value of a in y³ - 5y² + 72y - 68 = 0 is -5

It's an Irregular Quadrilateral

Step-by-step explanation:

It has 4 sides and the length of the sides of the Quadrilateral is not equal. This makes it irregular.

Answer:

Irregular Polygons

Step-by-step explanation:

Let's us first learn the definition of a polygon. A polygon is a closed shape figure that has a minimum of three sides and three vertices. The term ‘poly’ means ‘many’ and ‘gon’ means ‘angle’. Thus, polygons have many angles. The perimeter and area of polygon depend upon its types.

The classification of polygons is described based on the numbers of sides and vertices. For example, a polygon as four sides and four angles, then it is quadrilateral. The polygons up to 12 sides are the important ones. We are going to learn here polygon’s types based on the number of sides of the closed figure along with examples and diagrams.

Polygons are classified into various types based on the number of sides and measures of the angles. They are:

In a regular polygon, all the sides of the polygon are equal, and all the interior angles are the same. For example, a regular hexagon has six equal sides, and all its interior angles measure to 120 degrees.

A polygon with an irregular shape. It means the sides and angles of the polygon are not equal.

In a convex polygon, the measure of the interior angle is less than 180 degrees. It is exactly opposite to the concave polygon. The vertices of a convex polygon are always outwards

In a concave polygon, at least one angle measures more than 180 degrees. The vertices of a concave polygon are inwards as well as outwards.

Trigons are polygons who have three sides. They are nothing but triangles. These trigons or triangles are further classified into different categories, such as:

Quadrilateral polygon is also called a four-sided polygon or a quadrangle. The different types of the quadrilateral polygon are square, rectangle, rhombus and parallelogram.

The five-sided polygon is called pentagon polygon. When all the five sides of the polygon are equal in length, then it is called regular pentagon otherwise irregular pentagon.

Another type of polygon is the hexagon which has 6 sides and 6 vertices. A regular hexagon will have equal 6 sides and all its interior and exterior angles also measure equals.

The polygons whose all the sides are equal are called equilateral polygons, for example, an equilateral triangle, a square, etc.

The polygons whose all the interior angles are equal such as a rectangle are called equiangular polygons.

Answer:

  y = 3x +1

Step-by-step explanation:

The line intersects the y-axis at y=1, so the y-intercept is ...

  b = 1

The line rises 3 grid squares for each 1 grid square to the right, so the slope is ...

  m = rise/run = 3/1 = 3

Then the slope-intercept equation of the line is ...

  y = mx +b

  y = 3x +1

Answer:

it'd be (0, 5) it sits on the y line so it's the only y intercept

Answer:

y=-3x+5

Step-by-step explanation:

It start from its starts from 5 on the y axis, and goes down by 3 so its negitive. So y=-3x+5

Your answer is 2.042

Step-by-step explanation:

If you want it simplified you can change it to

2.0/2.04.

The decimal notation of two and forty-two thousandths is 2.042.

Given that, two and forty-two thousandths.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Here, 2+42/1000

= 2+0.042

= 2.042

Therefore, the decimal notation of two and forty-two thousandths is 2.042.

Answer:

37 in (to the nearest inch)

Step-by-step explanation:

Assume the TV is rectangular  ⇒  each corner is a right angle.

We need to find the length of the diagonal, so we can use Pythagoras' Theorem  a² + b² = c²  where a and b are the legs and c is the hypotenuse (diagonal) side of a right angled triangle.

In this diagram, a and b are the height and width, and the diagonal (c) is the hypotenuse.

Therefore, if a = 18  and   b = 32 then:

  18² + 32² = c²

324 + 1024 = c²

               c² = 1348

                c = √(1348)

               c  = 36.7151195...  

               c  = 37 (rounding up to the nearest integer)

Therefore, the diagonal distance is 37 in (to the nearest inch)

Using the t-distribution, we have that:

a. The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.

b. The 99% confidence interval to estimate the true mean score on this question is (0.6479, 1.8861). It means that we are 99% that the true mean score of all students in this question is between 0.6479 and 1.8861.

We have the standard deviation for the sample, hence the t-distribution is used to solve this question.

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

In this problem, the parameters are:

[tex]n = 30, \overline{x} = 1.267, s = 1.23[/tex]

Item a:

The standard error is:

[tex]S_e = \frac{s}{\sqrt{n}} = \frac{1.23}{\sqrt{30}} = 0.2246[/tex]

The standard error is of 0.2246, which means that the mean scores for samples of 30 vary around 0.2246 from the mean.

Item b:

Using a t-distribution calculator, considering a confidence level of 0.99 with 30 - 1 = 29 df, the critical value is t = 2.7564.

Hence:

[tex]\overline{x} \pm tS_e[/tex]

[tex]\overline{x} - tS_e = 1.267 - 2.7564(0.2246) = 0.6479[/tex]

[tex]\overline{x} + tS_e = 1.267 + 2.7564(0.2246) = 1.8861[/tex]

The 99% confidence interval to estimate the true mean score on this question is (0.6479, 1.8861). It means that we are 99% that the true mean score of all students in this question is between 0.6479 and 1.8861.
