The 125 is the median number of calories per serving for the breakfast cereals.

What is median?

The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data set more accurately than the average does. It represents the midpoint of the data because it is the point above and below which half (50%) of the observed data falls.

Given:

The box-and-whisker plot below shows the distribution of the numbers of calories per serving for a selection of breakfast cereals.

We have to find the median.

Since median is the middle most number of the given list of numbers.

In the given list there are 11 numbers.

The middle most number is occur at 5th number.

The number on 5th place is 125.

Hence, the 125 is the median number of calories per serving for the breakfast cereals.

What is polynomial?

An expression that consists of variables, constants, and exponents and is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Given: f(x) = tan(2x)

Then f(5.4) = tan(2 x 5.4) = tan(10.8) = tan(54/5)

The second degree Taylor polynomial centered at x =  5 is given by,

T2(x) = Σ(n = 0, 2) f^n(5)/5!(x - 5)^n

Now,

f°(x) = f(x) = tan(2x)

f(5) = tan(2 x 5) = tan(10)

f'(x) = d/dx(tan(2x))

f'(x) = 2 sec^2x = 2( 1 + tan^2(x))

f'(5) = 2(1 + tan^2(10))

f"(x) = d/dx[2(1 + tan^2(2x)]

f"(x) = 0 + 2(2tan(2x)(2sec^2(2x))

f"(x) = 8 tan(2x)(1 + tan^2(2x))

f"(5) = 8 tan(10)(1 + tan^2(10)

Then

[tex]T_2(x) = \frac{tan(10)}{0!}(x - 5)^0 + \frac{2 + 2tan^210}{1!}(x - 5)^1 + \frac{8(tan(10)(1+tan^2(10)}{2!}(x - 5)^2 \\T_2(5.4) = tan(10) + 2(1 + tan^2(10)) (5.4 - 9) +4tan(10)(1 + tan^2(10)(5.4 - 5)^2\\T_2(5.4) = \frac{16}{25} tan^310 + \frac{4}{5}tan^2(10) + \frac{41}{25} tan(10) + \frac{4}{5}[/tex]

The absolute difference is,

[tex]|f(5.4) - T_2(5.4)| = 2.673745[/tex]

|f(5.4) - T2(5.4)| ≈ 2.674

Divide through the matrix by 2

This gives

X = (-2 0 4)

Solving matrix B, we have the following representations

3 X-(1 7)=(-16 -4)

Rewrite the equation properly

So, we have

Answer:

x = 2

Step-by-step explanation:

Given equation,

→ 4x - 22 = -14

Now the value of x will be,

→ 4x - 22 = -14

→ 4x = -14 + 22

→ 4x = 8

→ x = 8/4

→ [ x = 2 ]

Hence, the value of x is 2.

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

What are Functions?

A function from a set X to a set Y allocates precisely 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.

The function is H(d) = 16 + 1.5d

Since, all the options talks aabout the height of the plant after 22 days

We need to put the value of d as 22 in the function for calculating the height of the function

The equation of the line passing through the points (-3,-15/2) and(1,-3/2) is  3x - 2y - 6 = 0.

What is the equation of a line?

An algebraic way to represent a collection of points that together make a line in a coordinate system is called the equation of a line. An algebraic equation, commonly known as the equation of a line, can be created using the various points that together make up a line in the coordinate axis as a collection of variables (x, y). It is possible to determine whether a specific point lies on a line by utilising the equation of a line.

The equation of a line passing through two points [tex](x_{1} ,y_{1} )[/tex] & [tex](x_{2},y_{2})[/tex] is given by

               [tex]\frac{y-y_{1} }{x-x_{1} } = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Given, two points are  (-3,-15/2) and(1,-3/2).

[tex](x_{1} ,y_{1} )[/tex] = (-3,-15/2) and  [tex](x_{2},y_{2})[/tex] = (1,-3/2).

So, The equation of line passing through (-3,-15/2) and (1,-3/2) is given by

or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{-\frac{3}{2} +\frac{15}{2} }{1 +3 }[/tex]

or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{6}{4 } =\frac{3}{2}[/tex]

or, 2(y+7.5) = 3(x+3)

or, 2y + 15 = 3x + 9

or, 3x - 2y - 6 = 0

Hence, the required equation of the line is 3x - 2y - 6 = 0.

What is sum of angles of a triangle?

A triangle's total angles equal the straight angle (180 degrees, radians, two right angles, or a half-turn) in a Euclidean space. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle.

For a very long period, it was unknown if there were any alternative geometries for which the total is different. During the 19th century, this issue had a particularly significant impact on mathematics. Ultimately, it was determined that the response was correct: in other geometries, this total can be higher or smaller, but it must then depend on the triangle. Its deviation from 180° represents an instance of an angular defect and is a crucial distinction for geometric systems.

From the fig.

we know,

e=37

b= 143 (vertically opposite angle)

143  +  a = 180 (Linear pair)

a =  180 - 143

a  =  37

e = 37

So,  c = 37 (Vertically opposite angle)

c + d + 85 = 180 (Sum of angles on straight line)

37 + d +  85 = 180

d = 180 - 122

d = 58

e + 90 + f = 180 (Sum of all angles of a triangle)

37 + 90 + f = 180

f = 180 - 127

f = 53

g = 48 (if two sides are equal , then the two angles opposite to the equal    

             sides will also be equal.)

48 + 48 + h = 180 (Sum of angles of a triangle)

h = 180 - 96

h = 94

h+ k = 180 (Linear pair)

94 + k = 180

k = 180 - 94

k = 96

d + k + m = 180 (Sum of angles of a triangle)

58 + 96 + m = 180

m = 180 - 154

m = 26

26 + 85 + p = 180 (Sum of angles of a triangle)

p = 180 - 111

p = 69

p + r = 180 (Linear pair)

r = 180 - 69

r = 111

p = s (corresponding angles)

s = 69

Hence all angles are:

a = 37

b = 143

c = 37

d = 58

e = 37

f = 53

g = 48

h = 94

k = 96

The first question:-5/2 is the sloop

second question: 5/2 is the sloop

Step-by-step explanation:

a.

correct, the population was 18.5 million in 2000.

why ?

t = years after 2000.

so, if the year is 2000, t = 0.

A(0) = 18.5e^(0.1708 × 0)

you remember, a⁰ = 1 for any a.

so,

A(0) = 18.5×e⁰ = 18.5×1 = 18.5 million.

b.

we need to find the value of t for which A(t) = 26.6.

26.6 = 18.5e^(0.1708 × t)

26.6/18.5 = e^(0.1708 × t)

ln(26.6/18.5) = 0.1708 × t

t = ln(26.6/18.5)/0.1708 = 2.126115244... years

≈ 2 years

2 years after 2000 is 2002.

it will reach 26.6 million in the year 2002.
