a meteorologist is concerned about the number of tornadoes in her county. using data from the past 10 years, she randomly selected 250 days from the peak season and found that a tornado was reported on 22 of these days. she conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of days with a tornado during peak season is greater than 5%. (a) which answer choice shows the correct null and alternative hypotheses for this test?

it is a polynomial of degree 1 ( it means that it is a linear polynomial ) in 1 variable

Answer: monomial

Step-by-step explanation:

 You need to classify the polynomial 9x.

We need to keep in mind that the basic classifications of polynomials are:

Monomials  

Binomials

Trinomials

Polynomials

What are monomials?

  Monomials are expressions with one term.

What are binomials?

 Binomials are expressions with two terms.

What are trinomials?

 Trinomials are expressions with three terms.

What are polynomials?

 Polynomials are expressions with four or more terms.

How many terms does 9x have?

 It has only one term. So it's a monomial.

\(\therefore\) it is a monomial

Answer:

B. (2, 3)

Step-by-step explanation:

Difference in x-coordinates of points A and B:

5 - (-4) = 9

2/3 of the difference is:

2/3 × 9 = 6

Add the difference to the x-coordinate of point A:

-4 + 6 = 2

The x-coordinate is 2.

Difference in y-coordinates of points A and B:

5 - (-1) = 6

2/3 of the difference is:

2/3 × 6 = 4

Add the difference to y-coordinate of point A:

-1 + 4 = 3

The y-coordinate is 3.

Answer: B. (2, 3)

Take $2.46 and divide it by 6 because that is the number of cans in the pack, the answer is $0.41 per can.

Answer:

Yes

Step-by-step explanation:

A function would be f(x), a output for each x input.

The slope intercept form is y - mx + b! *keep this in mind*

If you graph this as well, it would be easier to see if its a function too. If the line crosses through it once, it is indeed a function. If it doesn't, it isn't

The first step is to describe the method to take

To solve the system of equations 4x + 2y = 11 and 3x - y = 9, the first step would be to choose a method to solve the system.

There are several methods for solving systems of equations, including:

One common method is the substitution method, which involves solving one equation for one variable and then substituting the expression for that variable into the other equation.

For example, we could solve the second equation 3x - y = 9 for y to get:

The x-intercepts with multiciplity greater than 1 is x = 0

The number of distinct intercepts is 3 and the number of zeros is 4

From the question, we have the following parameters that can be used in our computation:

f(x) = x²(x + 2)(x - 7)

The x-intercepts with multiciplity greater than 1 is the factor that has a power greater than 1

So, we have

x² = 0

This gives

x = 0

The number of distinct intercepts is the number of factors i.e. 3

The number of zeros is the sum of powers

i.e. Zeros = 2 + 1 + 1

Step-by-step explanation:

The computed value of the test statistic is 2.94.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We have a sample size of n = 12, engine size (x) and emissions (y) are the two variables being correlated, and the sample correlation coefficient is r = 0.47.

The null hypothesis is that the population correlation is zero (H0: ρ = 0) and the alternative hypothesis is that the population correlation is positive (Ha: ρ > 0).

To compute the test statistic, we need to first calculate the degrees of freedom (df), which is (n-2) = 10 in this case.

We can then use the formula for the test statistic, which is:

t = (r√(df)) / √1 - r²

Substituting the values we have, we get:

t = (0.47 √10) / √(1 - 0.47²)

t = 2.94

Therefore, the computed value of the test statistic is 2.94.

Answer:

Graph E

You're welcome.

We can use Coulomb's law to calculate the magnitude of the electric field at a distance r away from a point charge Q:

E = k * Q / r^2

where k is Coulomb's constant, Q is the charge of the point charge, and r is the distance from the point charge.

In this problem, we have a point charge Q of -10 nC located at (1.2 cm, 0 cm), and we want to find the x-component of the electric field at a distance r = 5.3 cm away at position (-4.1 cm, 0 cm).

To find the x-component of the electric field, we need to use the cosine of the angle between the electric field vector and the x-axis, which is cos(180°) = -1.

So, the x-component of the electric field at position (-4.1 cm, 0 cm) is:

E_x = - E * cos(180°) = - (k * Q / r^2) * (-1)

where k = 9 x 10^9 N*m^2/C^2 is Coulomb's constant.

Substituting the given values, we get:

E_x = - (9 x 10^9 N*m^2/C^2) * (-10 x 10^-9 C) / (0.053 m)^2

E_x ≈ -30,566.04 N/C

Rounding this to two significant figures and including the appropriate units, we get:

The x-component of the electric field is about -3.1 x 10^4 N/C (to the left).

In this question, we are asked to determine the truth-values of two statements involving sets A and B. For each statement, we need to determine if it is true or false. If it is false, we need to provide specific counterexamples by choosing appropriate sets A and B.

a. (A\B) ⊆ A

The statement (A\B) ⊆ A is true for any sets A and B. This is because the set difference (A\B) contains elements that are in A but not in B. Therefore, by definition, every element in (A\B) is also an element of A. There are no counterexamples to this statement.

b. A^c ⊆ (AUB)

The statement\(A^c\) ⊆ (AUB) is true for any sets A and B. This is because the complement of A, denoted as \(A^c\), contains all elements that are not in A.

On the other hand, the union of A and B, denoted as (AUB), contains all elements that are in A or in B or in both.

Since the complement of A contains all elements not in A, it includes all elements in B that are not in A as well.

Therefore, \(A^c\) ⊆ (AUB) holds true for any sets A and B. There are no counterexamples to this statement.

In conclusion, both statements are true for any sets A and B, and there are no counterexamples.

The surface area of the rectangular prism is 36 square units

How to find the surface area of the rectangular prism with help of net of the prism?

To find the surface area of the rectangular prism, we need to add up the areas of all six faces. We can use the net of the rectangular prism to visualize each face and calculate its area.

Here is the net of the rectangular prism with its dimensions labeled.

The top and bottom faces are both rectangles with dimensions 5×2, so each of their areas is 5 × 2 = 10.

The front and back faces are also rectangles with dimensions 5×2, so each of their areas is also 10.

Finally, the left and right faces are rectangles with dimensions 2×2, so each of their areas is 2 × 2 = 4.

Therefore, the total surface area of the rectangular prism is 2(10) + 2(4) + 2(4) = 20 + 8 + 8 = 36

Therefore, the surface area of the rectangular prism is 36 square units.

The slope of the equation is -2/3, and the y-intercept is 490.

To change the equation 2x + 3y = 1,470 to slope-intercept form (y = mx + b), where m represents the slope and b represents the y-intercept, we need to solve for y.

Starting with the given equation:

2x + 3y = 1,470

First, let's isolate y by subtracting 2x from both sides of the equation:

3y = -2x + 1,470

Next, divide both sides of the equation by 3 to solve for y:

y = (-2/3)x + 490

Now we have the equation in slope-intercept form, y = (-2/3)x + 490.

From this form, we can identify the slope and y-intercept:

The slope (m) is the coefficient of x, which is -2/3.

The y-intercept (b) is the constant term, which is 490.

Therefore, the slope of the equation is -2/3, and the y-intercept is 490.

To create passwords that are eight characters long and must include at least one letter and one digit, the possible combinations of letters and digits should be calculated. This is done using the multiplication principle.

The multiplication principle states that if there are m ways to do one thing and n ways to do another, then there are m × n ways to do both. In this case, there are 26 possible letters and 10 possible digits. Therefore, there are 26 × 10 = 260 ways to choose the first character. Since each character is chosen independently of the others, there are 260 ways to choose the second character, and so on.Therefore, the number of possible passwords that can be created that are eight characters long and must include at least one letter and one digit is:
