Answer:

A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample

Step-by-step explanation:

In statistics we have to deal with populations and samples to carry out our studies. A population is a large group under consideration and the elements or members of the population have some common features or attributes. For example, all the school going kids in a certain town will be considered a population. Sample on the other hand is a subset(a part) of the population. For example, all school going kids in the town aged 5-6 years will be considered a sample.

The term Parameter and Statistic are very similar as they represent some numeric description. Parameter represents the data of the entire population, while statistic represents that data of a sample. An easy way to remember this is to match the initials i.e. Parameter for Population and Statistic for Sample.

Considering this, we can say the correct answer is:

A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample

A parameter is a numerical value describing a characteristic of a population whilst a statistic is a numerical value describing a characteristic of a sample. A population is any whole set, while a sample is a subset of the population.

The primary difference between a parameter and a statistic lies in the data they refer to. A parameter is a numerical measurement that describes a characteristic of a population. A population is the whole set of items or individuals that we are interested in. On the other hand, a statistic is a numerical measurement that describes a characteristic of a sample, where a sample is a subset of the population.

For example, if we were to measure the average height of all adult men in a certain city (the population), the resulting value would be a parameter. If we were to take a sample group of 100 men from that city and measure their average height, the resulting value would be a statistic.

Answer:

y = 3(x + 2) + 2 and y = -3(x + 2) + 2

Step-by-step explanation:

* Lets revise the equation of the hyperbola with center (h , k) and

 transverse axis parallel to the y-axis is (y - k)²/a² - (x - h)²/b² = 1

- The coordinates of the vertices are  (h , k ± a)

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

- The coordinates of the foci are (h , k ± c) where c² = a² + b²

- The equations of the asymptotes are  ± a/b (x - h) + k  

* Lets solve the problem

∵ The equation of the hyperbola is (y - 2)²/9 - (x + 2)² = 1

∵ The form of the equation is (y - k)²/a² - (x - h)²/b² = 1

∴ h = -2 , k = 2  

∴ a² = 9

∴ a = √9 = 3

∴ b² = 1

∴ b = √1 = 1

∵ The equations of the asymptotes are y = ± a/b (x - h) + k  

∴ The equations of the asymptotes are  y = ± 3/1 (x - -2) + 2

∴ The equations of the asymptotes are  y = ± 3 (x + 2) + 2    

* The equations of the asymptotes of the hyperbola are

  y = 3(x + 2) + 2 and y = -3(x + 2) + 2

Answer: 5,4,2 -C

The zeros of the function f(x) = (x-5)(x-4)(x-2) are 5, 4, 2

Option C is correct

Note that:

The zeros of a function f(x) are the values of x that makes f(x) to be equal to zero

If f(x)  =  (x - a)(x - b)(x - c), then the zeros of the function f(x) are:

x  = a,  x  =  b,  x  =  c

Therefore, the zeros of f(x)=(x-5)(x-4)(x-2) are found by equating f(x) to zero

(x - 5)(x - 4)(x - 2)  =  0

Equate each of the terms to zero

x  -  5  =  0

x  =   5

x  -  4  =  0

x   =  4

x  -  2  =  0

x   =  2

The zeros of the function f(x) = (x-5)(x-4)(x-2) are 5, 4, 2

Answer:

Factored form of A-B is: (5-3p^4)(25+15p^4+9p^8)

Option A is correct.

Step-by-step explanation:

Given:

A= 125

B = 27p^12

To find: A-B

A-B = 125 - 27p^12

A-B=(5)^3-(3p^4)^3

We know that, a^3 - b^3 = (a-b)(a^2+ab+b^2)

Using this formula and finding factored form of A-B:

=(5-3p^4)((5)^2+(5)(3p^4)+(3p^4)^2)

=(5-3p^4)(25+15p^4+9p^8)

So, factored form of A-B is: (5-3p^4)(25+15p^4+9p^8)

Option A is correct.

Divide the data set in 4 equal parts.

(6, 6, 7), 7, (7, 8, 8), 8, (8, 8, 8), 9, (9, 9, 10)

[tex]Q_1=7, Median=8, Q_3=9[/tex]

IQR of the Asian elephant is

[tex]IQR=Q_3-Q_1=9-7=2[/tex]

IQR of the Asian elephant is 2.

If the data set lies in interval [tex][Q_1-1.5(IQR),Q_3+1.5(IQR)][/tex], then the data set has no outliers.

[tex][Q_1-1.5(IQR),Q_3+1.5(IQR)]=[7-1.5(2),9+1.5(2)]=[4,12][/tex]

All the data lie in [4,12], therefore Asian elephant  has no outliers.

Answer:

The inverse is g(x)=-x+5.

Both f and g have domain and range all real numbers.

In interval notation that is [tex](-\infty,\infty)[/tex]

Step-by-step explanation:

f(x)=-x+5 is a linear function.

Since isn't f(x)=constant then it is diagonal so this means the range is all real numbers.

For any linear function, the domain will be all real numbers.  

So to find the inverse of y=-x+5, you interchange x and y and resolve for y.

y=-x+5

(interchange)

x=-y+5

(solve for y)

Subtract 5 on both sides:

x-5=-y

Multiplying both sides by -1:

-x+5=y

So the inverse is g(x)=-x+5. To find find the domain and range of the inverse function given you already did it for the original function, the sets are swapped.  The sets were the same here because they were both all real numbers.

[tex]f(x)=x^{4}+x^{3}-7x^{2}-x+6[/tex]

Step-by-step explanation:

The zeros of the polynomial are: -3, -1, 1, 2

According to the factor theorem, the factors of the polynomial will be:

(x - (-3)) = x + 3

(x - (-1)) = x + 1

(x - 1)

(x - 2)

Since we have the factors, we can multiply them to obtain the equation of the polynomial.

So,

[tex]f(x)=(x+3)(x+1)(x-1)(x-2)\\\\ f(x)=(x+3)(x^{2}-1)(x-2)\\\\ f(x)=(x^{2}-1)(x^{2}-2x+3x-6)\\\\ f(x)=(x^{2}-1)(x^{2}+x-6)\\\\ f(x)=x^{4}+x^{3}-6x^{2}-x^{2}-x+6\\\\ f(x)=x^{4}+x^{3}-7x^{2}-x+6[/tex]

The above equation give the polynomial with integer coefficients and a leading coefficient of 1

The polynomial of degree 4 that has -3, -1, 1, and 2 as its real zeros and integer coefficients with a leading coefficient of 1 can be expressed in its factored form as f(x) = (x + 3)(x + 1)(x - 1)(x - 2).

To form a polynomial with the given real zeros and degree, we must first understand that each real zero corresponds to a factor of the form (x - a), where a is the zero.

Therefore, given the zeros -3, -1, 1, and 2,

the corresponding factors of the polynomial are (x + 3), (x + 1), (x - 1), and (x - 2).

The polynomial of degree 4 with these zeros can then be written as the product of these factors,

obtaining f(x) = (x + 3)(x + 1)(x - 1)(x - 2).

Since it's required that polynomial has integer coefficients and a leading coefficient of 1,

we leave it in this factored form.

We have the mean is 12.6 and

that 11 occurs 4 times, 12 occurs 7 times, 13 occurs 9 times, and 14 occurs f times.

How many children are there in all (that is the sum of the frequencies).

4+7+9+f

20+f

Alright so the mean could be found by doing:

[tex]\frac{4(11)+7(12)+9(13)+f(14)}{20+f}[/tex]

But we are given this is also equal to: 12.6.

So we have

[tex]\frac{4(11)+7(12)+9(13)+f(14)}{20+f}=12.6[/tex]

I'm going to simplify what I can on top.

[tex]\frac{245+14f}{20+f}=12.6[/tex]

I'm going to write 12.6 as [tex]\frac{12.6}{1}[/tex] because I want to cross multiply:

[tex]\frac{245+14f}{20+f}=\frac{12.6}{1}[/tex]

[tex](245+14f)(1)=12.6(20+f)[/tex]

Distribute:

[tex]245+14f=252+12.6f[/tex]

Subtract 12.6f on both sides:

[tex]245+1.4f=252[/tex]

Subtract 245 on both sides:

[tex]1.4f=7[/tex]

Divide both sides by 1.4:

[tex]f=5[/tex]

There are five 14 years old.

The top tag price you could pay for the shorts = $32.71....

Step-by-step explanation:

Total amount = $ 60.00

Cost of jacket = $25.50

Sales tax = 7% = .07

First of all find the total price of the jacket including sales tax.

25.50* .07 = 1.79( this is the sales tax)

Now add this sales tax into the original price.

25.5 + 1.79 = 27.29

Total price of a jacket = $27.29

Now subtract the total amount by the amount of the jacket.

$60.00 - $27.29 = $32.71

Thus the top tag price you could pay for the shorts = $32.71....

Ari will think that there is not enough ice cream for the amount of caramel.

3:5 and 6:8 are not equivalent

But let's prove that;

We know that 3 x 2 is 6, so let's multiply 3 x 2 and 5 x 2, when we do so, we get 6:10.

6:10 is greater than 6:8, so there is obviously less ice cream for the amount of caramel.

Answer:

Fixed cost is the weekly cost of the rent payment for the factory i.e. $2,250

Variable cost can be computed as :

Variable cost = Total wages paid + Cost of raw material

Variable cost = (20 workers × 40hrs/week × $15) + ($10/unit × $500 units)

Variable cost = $17,000

∴ The Total Cost is given as:

Total Cost = Fixed Cost + Variable Cost

Total Cost = $2,250 + $17,000 = $19,250

∴ Total variable cost is $17,000; total fixed cost is $2,250; total cost is $19,250

Answer:

The minimum number of lenses that Mira must purchase is= 12 packs=600 lenses

Step-by-step explanation:

You know that one Telescope is made for:

2 lenses (they are purchased by packs of 50 (only 25 works for Telescopes)

1 tube (they are purchased by packs of 10)

1 eyepiece (they are purchased by packs of 30)

Then the minimum number of lenses Mira must purchase to make a set of telescopes with no leftover components other than the unusable lenses, should be a whole number that is divisible by 30 and 10.

You can calculate how many packs Mira Needs to purchased in order to find that number.

You Know that 2 lenses are needed for 1 Telescope and that they are purchased by packs of 50 where only 25 works for Telescopes

Then you can express that how:

Number of telescopes Mira can make from Lenses= (50/4)* Number of packages of lenses

Then If Mira purchases:

1 pack of lenses, she can make 12.5 telescopes (it's no divisible by 30 and 10)

2 packs of lenses, she can make 25 telescopes(it's no divisible by 30 and 10)

3 packs of lenses, she can make 37,5 telescopes(it's no divisible by 30 and 10)

4 packs of lenses, she can make 50 telescopes(it's no divisible by 30 and 10)

5 packs of lenses, she can make 62,5 telescopes(it's no divisible by 30 and 10)

6 packs of lenses, she can make 75 telescopes(it's no divisible by 30 and 10)

7 packs of lenses, she can make 87,5 telescopes(it's no divisible by 30 and 10)

8 packs of lenses, she can make 100 telescopes(it's no divisible by 30 and 10)

9 packs of lenses, she can make 112,5 telescopes(it's no divisible by 30 and 10)

10 packs of lenses, she can make 125 telescopes(it's no divisible by 30 and 10)

11 packs of lenses, she can make 137,5 telescopes(it's no divisible by 30 and 10)

12 packs of lenses, she can make 150 telescopes(it's a whole number and is divisible by 30 and 10)

Then she needs to purchase 600 lenses, 5 packs of eyepieces and 15 packs of tubes in order to make 150 Telescopes.

Answer:

D. y[9]=15.5410

Step-by-step explanation:

Let's find the answer by using the following observation:

Notice that the y-value differences between consecutives obstacles are:

(y-value from obstacule 2) - (y-value from obstacule 1)= 7.975 - 7.25 = 0.725

which is equal to:

(y-value from obstacule 1) / 10 = 7.25 / 10 = 0.725

So, an equation can be written as follows:

y[i+1]=y[i]+y[i]/10 let's find the other values:

y[2]=7.25+(7.25/10)= 7.975

y[3]=7.975+(7.975/10)= 8.7725

y[4]=8.7725+(8.7725/10)= 9.64975

Notice that we obtained the same y-values using the formula as the ones reported. So using the same formulas we can calculate:

y[9]=15.5410

In conclusion, the general equation is y[i+1]=y[i]+y[i]/10 with a starting point (1, 7.25) and y[9]=15.5410. So the answer is D.
