A factor is just a number that completely divides another number, x=1,2,2 are factors.

Using mathematical operations like addition, subtraction, multiplication, and division, a polynomial is an equation made up of variables, constants, and exponents.

Here x³ - 5x² + 8x - 4 is the cubic polynomial  

Let's take x = 1 ,

=> 0=x - 1  

So, one of the factor = (x - 1)

Now,

By Division method, we get

=> (x³ - 5x² + 8x - 4) is Dividend

=>  (x - 1) is Divisor

=> (x² - 4x + 4) is Quotient

Now we will solve for,

(x)² - (4x) + 4

(x)² - (2x)- (2x) + 4

(x-2)X(x-2)

x=2,2

x=1,2,2 are factors.

Step-by-step explanation:

ans is in the attachment.

The area of square abcd is  be parallel lines passing through $a$, $b$, $c$, respectively is the 433.

Squares are quadrilaterals with four congruent aspects and four proper angles, and additionally they have units of parallel aspects. Parallelograms are quadrilaterals with units of parallel aspects. Since squares have to be quadrilaterals with units of parallel aspects, then all squares are parallelograms.

Here we have the values the distance between lines a and b is 12, and the distance between lines b and c is 17.

The distance is 12 and 17

x^2 = 12^2 + 17^2 = 144 +289 = 433

433 is the total that is the area of square of abcd.

Using the Real rate of return,

the real value of the invetment at the end of one year is $1058.

Real rate of return:

The real rate of return is the present value of the return on investment after taxes and inflation.

By considering the expected inflation rate and the effective interest rate in the compounding interval, we can derive the real interest rate.

Real Rate Of Return Formula,

Real rate of return = [( 1+ Nominal rate )/(1+ inflation rate) ] - 1

The principal amount of investment by Mr.X ( A)

= $1,000

The nominal or current rate of interest (i)= 10%

The rate of inflation ( π )= 4%

pulging all the values in above formula we get,

rate of return (R) =[ ( 1 + i ) /(1+π)] - 1

=> R =[ (1+0.1 )/(1+0.04) ] - 1 = (1.1 / 1.04 ) - 1

=> R = 0.05769(approx.)

=5.8%(approx.)

so, real rate of return = 5.8%

Real value of investment after a year = principle amount (A) + { real rate return × principle amount}

Real value of investment =$1,000+{5.8%×$1,000}

=$1,000+$58

=$1,058

Hence, real value of investment at the end of year is $1,058.

AB= 12                      AB=18

Step-by-step explanation:

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*24=15

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*36=18

Answer:

part a: AB = 12cm

part b: AB = 18cm

Step-by-step explanation:

sin(angle)=OPP/HYP

sine of an angle is a ratio of two sides of a right triangle. For sine, the ratio is the opposite side over the hypotenuse. In part a the marked angle is 30° and AB is the opposite side. The hypotenuse is given, 24cm.

So the sin 30°

= opp/hyp

= AB / 24

also given is the fact that sin30°=.5

Substitute that into our equation also.

sin30° = AB/24

.5 = AB/24

multiply both sides by 24.

.5×24 = AB

12 = AB

AB is 12 cm.

Part b is an identical calculation except the hypotenuse is 36cm.

sin30° = AB/36

.5 = AB/36

.5×36 = AB

18 = AB

AB is 18cm.

If both variable in a correlational study are non-numerical, the data can be organized in a matrix and then analyzed using a Chi-square hypothesis test.

A correlational study design investigates relationships between two variables (or more) without the researcher controlling or manipulating any of them.

Chi-square test for hypothesis tests about whether your data is as expected. The basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true.

The Chi-square statistic compares the size of any discrepancies between the expected results and the actual results, given the size of the sample and the number of variables in the relationship.

With including a new race time of 24.9s the mean will change from 21.9s to 22.5s by 0.6s

What is mean?

The mean is the average or the most common value in a collection of numbers.

In statistics, it is a measure of central tendency of a probability distribution along median and mode.

It is also referred to as an expected value.

According to the given question:

His initial mean would be calculated by:

His minimum race time = 18.9s

The maximum race time = 18.9 + 5.2 = 24.1s

Since the mode is also 24.1, there are two 24.1s races.

Since the median is 22.3s and the number of race times is even, the final race time can be calculated by:

24.1 - 22.3s = 1.8s

22.3 - 1.8 = 20.5s

So the race times are 18.9s, 20.5s, 24.1s and 24.1s.

This means that his initial mean was ( 18.9 + 20.5s + 24.1 + 24.1)/4 = (87.6)/4 = 21.9s

With the new race time, the equation will change to (87.6 + 24.9)/(4+1)= 112.5/5= 22.5s

So the mean change would be 22.5 - 21.9 = 0.6 s

A 95% confidence interval for population proportion p is (0.5336, 0.7213).

Given,

One difficulty in measuring the nesting success of birds is that the researchers must count the number of eggs in the nest, which is disturbing to the parents. Even though the researcher does not harm the birds, the flight of the bird might alert predators to the presence of a nest. To see if researcher activity might degrade nesting success, the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four of the nests failed (i.e. the parent abandoned the nest.)

To find,

Assuming that it is reasonable to regard the 102 nests in the sample as representative of the population of nests for which the eggs have been counted, construct and interpret a 95% confidence interval for the proportion of nests that have eggs counted that are then abandoned;

n = 102

x = 64

Point estimate = sample proportion = [tex]\hat p[/tex] = x / n = 64/102 =0.627

1 - [tex]\hat p[/tex] = 1 - 0.627 = 0.373

[tex]Z\alpha/2[/tex] = 1.96

The margin of error = E

                         [tex]= Z\alpha / 2 * \sqrt((\hat p * (1 - \hat p)) / n) = 1.96 * (\sqrt(0.627*(0.373) /102 ) = 0.0934[/tex]

Higher mean absolute deviation is an example of a measure of variability and range. It give us some information about how spread out the data in a data set is. When used together with measures of center like the mean and median, they can give us a useful overview of the data set.

For an example,

A chef wants to hire someone to work in his kitchen. There are two candidates: Sally and Nader. To test their abilities, he times how long it takes them to make each of four meals and records the data in two tables.

He decides to calculate the mean time it took each candidate to make the four meals; he is planning to hire the candidate with the lower (quicker) mean time.

The mean time it takes Sally to make a meal is

= 3+5+7+9 / 4

=24/6

= 6 minutes

The mean time it takes Nader to make a meal is

= 5+6+5+8 / 4

=24/4

= 6 minutes

After having mean times same he doesn't classify which one is best he used their statical graphs.

For Sally, the mean absolute deviation of her times is the mean of the distances,

=4+1+2+3 / 4

=2.5

For Nader, the mean absolute deviation of his times is

= 1+0+1+2 / 4

=1

The chef sees that the mean absolute deviation of Nader’s times is lower than the mean absolute deviation of Sally’s times. This shows that Nader is more consistent in his cooking times and agrees with what we observed from the bar graphs.

Which means that the higher mean absolute deviation occurs less consistency in the mean absolute deviation.
