No, the expression ( x - 1 ) as required to be checked is not a factor of the given polynomial function g ( x ) = -2x⁴ + 4x³ - x + 9.

It follows from the task content that the expression ( x - 1 ) is required to be checked if it's a factor of the given polynomial function.

Since the given factor can be equated to 0 so that we have; x - 1 = 0; x = 1.

On this when g (1) is evaluated, the result must be zero in order to confirm ( x - 1 ) is a factor of g ( x ) = -2x⁴ + 4x³ - x + 9.

Hence; g ( 1 ) = -2 ( 1 )⁴ + 4 ( 1 )³ - 1 + 9.

g (1) = -2 + 4 - 1 + 9

g (1) = 10

Ultimately, since g (1) ≠ 0; the expression ( x - 1 ) is not a factor of the given expression; g ( x ) = -2x⁴ + 4x³ - x + 9.

Hope this helps! :)

Answer:

False

Step-by-step explanation:

The test statistic calculated for this scenario is the test of the significance of the mean.

Mean is a measurement of a probability distribution's central tendency along the median and mode. It also goes by the name "anticipated value."

For example, if there are 3 students getting numbers 10, 20, and 30 in math then their mean is 10 + 20 + 30 / 3 = 60 / 3 = 20.

Given:

According to a survey of 1,362 adult college students, n = 1362,

The mean number of alcoholic beverages consumed, μ = 15,

The standard deviation, σ = 3,

As you can see here the sample is greater than 30 i.e. n > 30 and the value of standard deviation is also present then,

The static test, z can be given as shown below,

z = (X  - μ) / σ  / √n

Here, z is the static test and X is the sample mean.

Thus, the test of the significance of the mean can be calculated for this scenario.

Answer:

  3.  (a)  x, y ∈ W

  5.  (b)  x, y ∈ W

Step-by-step explanation:

Given two problems in which x and y represent numbers of seats, you want to know what, if any, domain the variables are restricted to.

A number of seats is a counting number, possibly including zero. Generally, it will be a member of the set of whole numbers: {0, 1, 2, 3, ...}. They will not be negative, and will not have a fractional part: x ≠ -1, x ≠ 2.3.

In both your problems, x and y are defined as numbers of seats, so will be from the domain of whole numbers.

  x ∈ W, y ∈ W

Additional comment

The various named domains are usually represented by ...

ℝ — real numbers

ℕ — natural numbers {1, 2, 3, ...}

ℚ — rational numbers

ℤ — integers

Step-by-step explanation:

The value of (p+q+r+s) / (a+b+c) is 3.66 if the basketball player has probability 0.4 to make a perfect shot.

We know that if probability is given for r distribution and if question is asking distribution for n terms, we need to use binomial probability distribution which is given by [tex]^nC_r[/tex][tex]p^r[/tex][tex]q^r[/tex] where p is defined as the success probability and q is called as failure probability.

We have success probability =0.4

Failure probability(q) = 1-p=1-0.4=0.6

From 9 terms, we need to choose single term having success probability =0.4 and failure probability=0.6

So, this can be given by =[tex]^9C_1[/tex] × (0.4)¹ ×(0.6)⁹⁻¹

which is equivalent to =9 × (0.4) × (0.6)⁸

On comparing with the given equation =([tex]p^a[/tex] × [tex]q^b[/tex]×[tex]r^d[/tex]) / [tex]s^c[/tex] ,we get

p=9,a=1,q=0.4,b=1,r=0.6,d=8,s=1,c=1.

So,value of p+q+r+s = 9+0.4+0.6+1=11

and value of a + b + c = 1+1+1=3

So, value of (p + q + r + s) / (a + b + c)= 11 / 3=3.66

Hence, required value is 3.66

Direction is characterized as the course that anything follows, the route that must be taken to go to a particular location, the direction in which something is beginning to take shape, or the direction you are facing. When you turn right instead of left, that is an illustration of direction.

The basis of the x, y, and z directions of a line or unit vector is identified by the number triplet known as the direction number. They are easily identified as a percentage of a unit vector.

u = 7cos300°i + 7sin300j

v = 4cos70i + 4sin70 j

u = 7*0.5i + 7*(-√3/2)j

  = 3.5i - 6.062j

v = 1.368i + 3.758j

u + v =(3.5+1.368)i +(-6.062+3.758)j

        = 4.868i +(-2.304)j

Magnitude of (u+v) = √(4.868)² +(2.304)²

It's True because zero cannot divided by any number it is undefined.

In mathematics, division by zero is division where the divisor (denominator) is zero. Such a division can be formally expressed as a/0, where a is the dividend (numerator). In ordinary arithmetic, the expression has no meaning, as there is no number that, when multiplied by 0, gives a (assuming a ≠ 0); thus, division by zero is undefined. Since any number multiplied by zero is zero, the expression 0/0 is also undefined; when it is the form of a limit, it is an indeterminate form. Historically, one of the earliest recorded references to the mathematical impossibility of assigning a value to a/0 is contained in Anglo-Irish philosopher George Berkeley's criticism of infinitesimal calculus in 1734 in The Analyst

The dilution formula indicates that the product of the concentration and volume of the initial solution is equivalent to the product of the concentration and volume of the intended solution to be made.

The volume of the 10% acetic acid solution in the mixture = 0.5 gallons

The volume of the 35% acetic acid solution = v

The concentration of the acetic acid solution Eli wants to make = 15%

The dilution formula for mixtures is; C₁·V₁ = C₂·V₂

Therefore; 0.1 × 0.5 + 0.35 × v = (v + 0.5) × 0.15

0.35 × v - (v + 0.5) × 0.15 = -0.1 × 0.5 = -0.05

0.2·v - 0.075 = -0.05

v = (0.075 - 0.05)/0.2 = 0.125

It is true that an interaction term can be used to properly examine the effect of a categorical independent variable in a multiple linear regression model.

In a multiple linear regression model, an interaction term is a product of two or more independent variables. It allows the model to capture the effect of the interaction between the variables on the dependent variable.

For example, suppose you are using a multiple linear regression model to examine the relationship between income, education level, and job satisfaction. You might include an interaction term for education level and income, which would allow the model to capture the effect of the interaction between these two variables on job satisfaction.

Using an interaction term can be especially useful when you want to examine the effect of a categorical independent variable on the dependent variable since it allows you to control for the effects of other variables in the model.

Answer:

A) 2y + x = 5. 5x - y = 3

Step-by-step explanation:

twice a number = 2y (y represents the larger number in this case)

added to a smaller number, so 2y + x (letting x represent the smaller number) equals 5, so 2y + x = 5

Then 5 times the smaller number, x = 5x

the difference of 5x and the larger number (y) = 5x - y = 3

so all together your equation would be 2y + x = 5. and 5x - y = 3.

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

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

y = -x/4 + 1/2 + 1

y = -x/4 + 3/2

The change at a constant additive rate is -1/4.

Therefore, In the picture the correct option is A when the function shown in graph (A) has a constant additive rate of change is -1/4.

The approximate distance from the playground to the road along the other path is 1.3 miles.

A town park has two paths leading to the playground. One path is 2 miles from the road and the other path makes a right angle with the road. The two paths intersect at an angle of  50 degrees.

The approximate distance from the playground to the road along the other path can be calculated as follows;

using trigonometric ratios,

cos 50° = adjacent / hypotenuse

let

x =  distance from the playground to the road along the other path

Hence,

cos 50 = x / 2

cross multiply

x = 2 cos 50°

x = 2 × 0.64278760968

x = 1.28557521937

x = 1.3 miles.

Therefore,

distance form play ground to the road = 1.3 miles.

The value of find f(-2)-g(-2), if f(a) = 3a + 5 and g(a) = a² + 4 is -9.

In the case of a function from one set to the other, each element of X receives exactly one element of Y. The function's domain and co-domain are respectively referred to as the sets X and Y as a whole.

Given function:

f(a) = 3a + 5 and g(a) = a² + 4

Calculate the f(-2) - g(-2) by putting value -2 in both function

f(-2) = 3(-2) + 5 = -6 + 5

f(-2) = -1

g(-2) = (-2)² + 4

g(-2) = 4 + 4

g(-2) = 8

Hence,  f(-2) - g(-2) = -1 - 8 = -9

Therefore, the value of find f(-2)-g(-2), if f(a) = 3a + 5 and g(a) = a² + 4 is -9.

Answer:

Below

Step-by-step explanation:

See image below

The given statement "A two-factor study compares 2 levels of factor A and 3 levels of factor B with a sample of n = 5 participants in each treatment condition. This study uses a total of 25 participants." is true.

The term probability refers the occurrence of a random event.

Here we have given the statement "A two-factor study compares 2 levels of factor A and 3 levels of factor B with a sample of n = 5 participants in each treatment condition. This study uses a total of 25 participants."

And we have to identify whether this one is true or not.

While looking into the given question, we have identified the value like the following,

level in factor A = 2

levels in factor B = 3

Number of participants = 5

Then the total number of participants is calculated as,

=> (3 + 2)  x 5

Now, we have to expand the given equation, then we get,

=> 5 x 5

Then the total number of participants is 25.

From the following obeservation done by Kate, the hypothesis that the population proportions is equal for all four locations is not true. Also, the population of male fish are not equal in all four locations and the p-value is greater than 0.10

A chi square ( χ2) test is performed in order to find a co relation between two unrelated variables. The main objective of the test is to prove whether the relationship holds true or is just a product of mere chance. For example, if we are conducting a survey of two different paramters, first being the population of people who are married and the other about their educational qualififcation, we will get two distinct table of values without any significant corelation. But now if we wnt to establish a relationship, lets say that married people have less educational qualifications, we need to prove our statement by performing a chi square test. The final value can either be a null hypothesis which states that their is no convinving relationship betwwen the two paramters or can be a alternate hypothesis with significant corelation.

For this problem lets focus on the male fish population alone and perform the test:

                                                       Population (Observed)

                              A                      B                    C                 D           TOT

Male fish                49                   44                   49               39           181

Female fish            41                    46                   36               44           167

                              90                   90                   85               83           348

                                                        Population(Expected)

Male fish                 46.81              46.81               44.20           43.16

Female fish              43.18             43.18               40.79           39.83

χ2 = ∑[tex]\frac{(Obsereved-Expected)^2}{Expected}[/tex];

=[tex]\frac{4.79}{46.81} +\frac{7.89}{46.81} +\frac{23.04}{44.20} +\frac{17.30}{43.16}[/tex]

= 0.10+0.16+0.52+0.40 = 1.18

Now to calculate degree of freedom= (coulmn-1)(row-1)= 3×1= 3.

Looking at the reference table at 0.05 significance level, the value shows 7.815

Thus as our value of 1.18 is less than the given value, null hypothesis cannot be rejected.

Hence the population proportions are not equal at all four locations. Whether this conclusive difference in gender proportions is due to varied contaminants cant be answered with this single observation and further tests are needed to be performed to construct a well found connection.
