Im doing the exact same thing lol

The sample = 4 pepper plants

The population = 36 pepper plants

We have to identify the sample and the population from the instance that heights of 4 out of 36 pepper plants are chosen.

Statistical studies are carried out on populations. So here there may be a study related to the heights of the pepper plants.

Sometimes, when the population is very large, studies are carried out on the samples taken from the population which gives not the exact but an approximately same result.

Hence in this case, the sample is the 4 plants chosen from the population of 36 plants at Mr. Lonardo's greenhouse.

Population: Population is the entire and broader group considered for collecting data on a statistical study.

Sample: Sample is the specific, comparatively small group selected from the population from which the data used for study is collected.

Answer:

(12, - 1)

Step-by-step explanation:

x - 2y = 14 ......... (1)

x + 3y = 9 ......... (2)

(x - x) + (3y - ( - 2y)) = 9 - 14

5y = - 5 ⇒ y = - 1

Unfortunately I’ve never written a two-column proof before. So I can’t do that. Let me know if what I can do helps at all though.

Step-by-step explanation:

A supplementary angle is an angle made up of two angles that have measures that add up to 180°. m∠2 = 45° because 45° added to 135° equals 180°. Therefore making it a supplementary angle. Meaning that m∠2 = 45° is true. Sorry if this doesn’t help. I tried my best.

Answer:

(4, 1)

Step-by-step explanation:

To find the second point, first, we must look at how far apart the midpoint and point A are from each other

As seen in picrel, the midpoint is 3 units up and 1 unit left from point A.

We will repeat these units diagonally to make a linear line to find the next point.

3 units up and 1 unit left from the midpoint is (4, 1) which is point B.

For future problems related to finding the second point with only the midpoint and the first point, refer to step 1.

By using the fact that the angles form a linear pair, we will see that the measure of angle C is 144 degrees.

Well, we know that these are a linear pair, which means that the angles are supplementary, thus, their measures add up to 180°.

So we can write:

C + D = 180°

Now, we also know that C is four times larger than D, so we can write:

C = 4*D

Replacing that in the equation above we get:

4*D + D = 180°

5*D = 180°

D = 180°/5 = 36°

Then we know that the value of D is 36°, and C is 4 times that, so:

C = 4*36° = 144°

The measure of angle C is 144 degrees.

Answer:

Answer:

3×+4(×+2 then f (4×)=21

The expression for f(4x) is 28x + 6. When you evaluate the function f at 4x, you obtain 28 times x + 6. For every value of x, you can plug it into the equation 28x + 6 to get f(4x).

To find the expression for f(4x), we substitute 4x for every occurrence of x in the original function f(x).

Given f(x) = 3x + 4(x + 1) + 2, we have to replace every x with 4x:

f(4x) = 3(4x) + 4(4x + 1) + 2

Now, simplify the expression:

f(4x) = 12x + 4(4x + 1) + 2

f(4x) = 12x + 16x + 4 + 2

f(4x) = 28x + 6

Therefore, the expression for f(4x) is 28x + 6.

This means that when you evaluate the function f at 4x, you get 28 times the value of x plus 6. So, for any given value of x, you can plug it into the expression 28x + 6 to get the corresponding value of f(4x).

Answer:

Step-by-step explanation:

smplifying

7x + 11 = 25

Reorder the terms:

11 + 7x = 25

Solving

11 + 7x = 25

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 7x = 25 + -11

Combine like terms: 11 + -11 = 0

0 + 7x = 25 + -11

7x = 25 + -11

Combine like terms: 25 + -11 = 14

7x = 14

Divide each side by '7'.

2. New Years Eve

Step-by-step explanation:

I hope you'll get Best lines for your Speech.

New Year’s Eve is a public holiday in places such as Latvia, the Philippines, and San Marino. It is a holiday for banks in countries such as Bangladesh, Brunei, Paraguay, and Japan (New Year’s Eve is also a government holiday in Japan).

New Year’s Eve is not a nationwide public holiday in countries such as Australia, Canada, the United Kingdom and the United States, but some businesses close early, schools are usually closed, and many people may have half a day off work. Those wishing to travel via public transport may need to check with the local transport authorities on public transport schedules for New Year’s Eve.

Background

New Year's Eve is the last day of the year and the day before New Year’s Day, which marks the start of a new year according to the Gregorian calendar. Pope Gregory XIII introduced the Gregorian calendar in 1582. It was adopted immediately in some areas of Europe but it was not used in various countries until even centuries later. For example, the United Kingdom and the United States started observing the Gregorian calendar in 1752, in which 11 days were dropped.

New Year’s Eve festivities can be traced back to celebrations in Europe that date back before Christianity spread. When many inhabitants in Europe were converted to Christianity, these festivals were merged with Christian beliefs and in time came to mark holidays such as the New Year’s Eve and New Year celebrations.

It is important to note that not all cultures follow the Gregorian calendar in observing New Year’s Eve and New Year’s Day. For example the New Year in the Hindu, Chinese, Coptic, Jewish, Islamic calendars differ to that of the Gregorian calendar.

Symbols

New Year’s Eve and New Year’s Day are symbolized in various ways across the world. Midnight between New Year’s Eve and New Year’s Day is often marked by fireworks and fire crackers. Many people drink and toast with champagne or other sparkling wine.

Not sure question is complete, assumptions however

Answer and explanation:

Given the above, the function of the population of the ants can be modelled thus:

P(x)= 1600x

Where x is the number of weeks and assuming exponential growth 1600 is constant for each week

Assuming average number of ants in week 1,2,3 and 4 are given by 1545,1520,1620 and 1630 respectively, then we would round these numbers to the nearest tenth to get 1500, 1500, 1600 and 1600 respectively. In this case the function above wouldn't apply, as growth values vary for each week and would have to be added without using the function.

On one hand, the function above could be used as an estimate given that 1600 is the average growth of the ants per week hence a reasonable estimate of total ants in x weeks can be made using the function.

Answer:

The dilation on any point of the rectangle is [tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex].

Step-by-step explanation:

From Linear Algebra, we define the dilation of a point by means of the following definition:

[tex]G'(x,y) = O(x,y) +k\cdot [G(x,y)-O(x,y)][/tex] (1)

Where:

[tex]G(x,y)[/tex] - Coordinates of the point G, dimensionless.

[tex]O(x,y)[/tex] - Center of dilation, dimensionless.

[tex]k[/tex] - Scale factor, dimensionless.

[tex]G'(x,y)[/tex] - Coordinates of the point G', dimensionless.

If we know that [tex]O(x,y) = (0,0)[/tex], [tex]G(x,y) =(2,-2)[/tex] and [tex]G'(x,y) =(5,-5)[/tex], then scale factor is:

[tex](5,-5) = (0,0) +k\cdot [(2,-2)-(0,0)][/tex]

[tex](5,-5) = (2\cdot k, -2\cdot k)[/tex]

[tex]k = \frac{5}{2}[/tex]

The dilation on any point of the rectangle is:

[tex]P'(x,y) = (0,0) + \frac{5}{2}\cdot [P(x,y)-(0,0)][/tex]

[tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex] (2)

The dilation on any point of the rectangle is [tex]P'(x,y) = \frac{5}{2}\cdot P(x,y)[/tex].

Algebraic representation of the dilation will be T'(x, y) → T(2.5x, 2.5y).

        Rule for the transformation will be,

        [tex]D_{(o,k)}(x,y)\rightarrow (kx,ky)[/tex]

    Following this rule,

        [tex]D_{(o,k)}(2, -2)\rightarrow (2k, -2k)[/tex]

        Since, coordinates of the dilated point are G'(5, -5),

        Therefore, (2k, -2k) = (5, -5)

        ⇒ 2k = 5

        ⇒ k = 2.5

        Hence, algebraic representation defining the dilation of the

        triangle will be,

        T'(x, y) → T(2.5x, 2.5y)

   Algebraic representation of the dilation will be T'(x, y) → T(2.5x, 2.5y).

Answer:

Step-by-step explanation:

Vertex form of quadratic equation is

[tex]y = a(x-h)^2 + k[/tex]

where h and k are the x and y coordinates of the vertex, respectively.

so in this problem

if a=1 and Vertex is (-1,4) means h= -1 and k = 4

the equation will be

[tex]y = 1 (x-(-1))^{2} + 4[/tex]

[tex]y = (x+1)^2 + 4[/tex]

if a=-1 and Vertex is (-1,4) means h= -1 and k = 4

the equation will be

[tex]y = -1 (x-(-1))^{2} + 4[/tex]

[tex]y = -(x+1)^2 + 4[/tex]
