The next three numbers in the sequence are 27, 38, and 51

From the question, we are to determine the next three numbers in the given sequence

The given sequence is

2,3,6,11,18

The difference between the 1st and 2nd terms is 3 -2 = 1

The difference between the 2nd and 3rd terms is 6 -3 = 3

The difference between the 3rd and 4th terms is 11 - 6= 5

The difference between the 4th and 5th terms is 18 - 11= 7

We can observe that the successive odd numbers are being added to the terms

Thus,

The sixth term will be 18 + 9 = 27

The seventh term will be 27 + 11 = 38

The eight term will be 38 + 13 = 51

Hence, the next three numbers in the sequence are 27, 38, and 51

The equation that can be used to model the total number of yards of fabric, y. needed to make x curtain panels is y = (10 2/4 ÷ 4) × x

It should be noted that Mary used 10 2/3 yards of fabric to make 4 identical curtain panels.

Therefore, the equation that can be used to model the total number of yards of fabric, y. needed to make x curtain panels will be:

y = (10 2/4 ÷ 4) × x

where

y = number of yards

x = number of panels

Therefore, the equation is y = (10 2/4 ÷ 4) × x

Division is  one among  the four basic operations of arithmetic, the  ways in which  numbers are combined to make new numbers.  the opposite  operations are addition, subtraction, and multiplication.

At an elementary level the division of two natural numbers is, among other possible interpretations,  the method  of calculating the number of times one number is contained within another.7  This number of times  needn't  be an integer.  for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).

The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which  is that the  number of times the second number is completely contained in the first number, and a remainder, which  is that the  part of the first number that remains, when  within the  course of computing the quotient, no further full chunk of  the dimensions  of the second number can be allocated.  for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.

For division to always yield one number  instead of  a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.

This geometric progression has 5 terms

This is a geometric progression or geometric series whose sum of n terms is given by the formula

Sn = a[([tex]r^{n\[/tex] – 1)/(r – 1)]

Where Sn is sum of n terms of geometric progression, a is the first term of the series , r is the common ratio

Here we are required to find the number of terms in the geometric progression whose first term is -3 and common ratio is 6

-4665 = -3 [( [tex]6^{n}[/tex]-1)/(6-1)

1555=( [tex]6^{n}[/tex]-1)/5

7775= [tex]6^{n}[/tex]- 1

Vectors is a quantity that has both magnitude and direction as well. A vector that has 1 magnitude is called unit vector. Unit vector is represented by the symbol '^'.

To find a Unit vector we divide the vector by its magnitude.

First find the slope of the tangent line, slope of a tangent line for a point f(x) is given by f'(x). Hence at point (π/6,1) where x = π/6, the slope of the tangent line is :

[tex]f(x)=2sinx\\f'(x)=2cosx\\f'(\pi /6)=2cos(\pi /6)=2.\frac{\sqrt{3} }{2}=\sqrt{3}[/tex]

The slope of the tangent line at this point is [tex]m=\sqrt{3}[/tex]

Finding a unit vector parallel to the tangent line. since slope is the ratio y and x then we can set an arbitrary vector with slope 4 by letting x=1 and y = √3 or v=[1,√3]. this vector has slope √3 and this is parallel to the tangent line, However this is not unit vector because its magnitude is not equal to 1 so we can divide this vector by its magnitude to find the unit vector.

[tex]u_v=\frac{v}{|v|} =\frac{1 \sqrt{3} }{\sqrt{1^{2}+(\sqrt{3})^2 } } \\=\frac{1}{\sqrt{4} } ,\frac{\sqrt{3} }{\sqrt{4} } =\frac{1}{2}, \frac{\sqrt{3} }{2} =[\frac{1}{2},\frac{\sqrt{3} }{2} ][/tex]

If a line has slope of m then all lines perpendicular of it will have a slope of  -1/m

So we are looking for a unit vector of slope of -1/√3

Using the same logic we have unit vector that are perpendicular to the tangent line are [tex][\frac{\sqrt{3} }{2},-\frac{1}{2} ][/tex]

Answer: 27

Step-by-step explanation:

According to the given statement the values are:

The range = 19

Interquartile Range will be = 8.25

Sample Variance =33.93

Sample Standard deviation = 5.82

The dispersion of your data's middle quartile is measured by the interquartile range (IQR). It is the range for your sample's middle 50%. Assess geographical variability where the majority of your numbers are by using the IQR. Larger numbers suggest a wider dispersion of your data's center region.

According to the given data:

finding the range =  Maximum value + Minimum value

                            = 34 - 15

                            = 19

The range = 19When ordering the observations, we obtain:

15,20,24,26,26,27,30,34

Where ,

n = 8

Q1=(n+14)the observation's term value

=(94)the observation's term value

=(2.25)the observation's term value

=2nd observation +0.25[3rd-2nd]

=20+0.25[24-20]

=20+0.25(4)

=20+1

=21

Q3=(3(n+1)4)the observation's term value

=(3⋅94)the observation's term value

=(6.75)the observation's term value

=6th observation +0.75[7th-6th]

=27+0.75[30-27]

=27+0.75(3)

=27+2.25

=29.25

Now finding the Interquartile Range

= Q3 -Q1

= 29.25 - 21

=8.25

The  Interquartile Range will be = 8.25

Sample Variance S2=∑x2-(∑x)2nn-1

=5338-(202)28/7

=5338-5100.5/7

=237.57

=33.9286

Sample Variance =33.93

S=√∑x2-(∑x)2nn-1

=√5338-(202)28/7

=√5338-5100.5/7

=√237.5/7

=√33.9286
