The vertex of the quadratic equation in the graph is (-5, -9), so the correct option is A.

Here we have the graph of a quadratic equation and we want to find the vertex.

The vertex of a quadratic equation is the lowest/highest point of it. In the graph we can see that we have a minimum (where the curvature changes).

To identify the coordinates we can use the numbers in the coordinate axis of the graph.

We can see that the x-value is -5, and the y-value is -9.

Thus the vertex is at (-5,-9), which means that the correct option is A.

Step-by-step explanation:

Answer:

Ernie is incorrect.

Step-by-step explanation:

I suppose that we want to see if Ernie statement is correct or not.

Suppose that we have a line that passes through the points (x₁, y₁) and (x₂, y₂)

The slope of that line can be calculated as:

slope = (y₂ - y₁)/(x₂ - x₁)

In this case, we know that the line passes through (0, 0) and (3, 3), then the slope of this line is:

slope = (3 - 0)/(3 - 0) = 3/3 = 1

Then Ernie got the slope wrong, which means that he is wrong.

The variation between the groups is known as the variation between the treatments, and the variation within the groups is known as the variation within the treatments. The ANOVA produces two types of degrees of freedom, namely degrees of freedom between and degrees of freedom within. Therefore, each treatment has 9 participants.

The total number of participants required for all the treatments can be calculated by multiplying the number of treatments by the number of participants in each treatment. We can find the number of participants in each treatment by dividing the total number of participants by the number of treatments, given that each treatment has the same number of participants. Solution:

A total Given, df between = 3df within = 24Total df = df between + df within = 3 + 24 = 27The total number of participants required for all the treatments can be calculated as follows:

Total number of participants = Total df + Number of treatments= 27 + Number of treatments ………..(1)The degrees of freedom within treatments (df within) is calculated as:

df within = (Number of treatments – 1) x (Number of participants – 1) ………..(2)For all the treatments, the number of participants is the same; let it be x.

Substituting equation (2) in equation (1), we get:24 = (Number of treatments – 1) x (x – 1) ………..(3)For df between, the formula is given as:df between = Number of treatments – 1 ………..(4)Substituting equation (4) in equation (1), we get:3 = Number of treatments – 1 ………..(5)From equation (5), Number of treatments = 3 + 1 = 4 Substituting this value in equation (3), we get:24 = 3 x (x – 1)x – 1 = 8x = 8 + 1x = 9Therefore, each treatment has 9 participants.

Analysis of variance:

The line of the equation should be y = 20x + 320 and travelers will spend about $620 billion in the year 2008. So, the option c is correct.

In the given question, we have to write an equation for the line of best fit and then predict how much money travelers will spend in 2008.

The graph of the question is given below:

From the graph the points are (1.5, 350) and (4, 400)

As we know that the formula of the equation of line is:

y-y(1) = {y(2)-y(1)}/{x(2)-x(1)} (x-x(1))

x(1) = 1.5, y(1) = 350, x(2) = 4 and y(2) = 400

Now putting the values

y-350 = (400-350)/(4-1.5) (x-1.5)

y-350 = 50/2.5 (x-1.5)

y-350 = 20(x-1.5)

y-350 = 20x-30

Add 350 on both side, we get

y = 20x + 320

So, the line of the equation should be y = 20x + 320.

So that travelers will spend about $620 billion in the year 2008.

Hence, the option c is correct.

Answer:

f(x) = x^4-x^2+ 2

option D

Step-by-step explanation:

From the question, we are told that the graph of g(x) contains the point (0,0)

What the graph of f(x) is showing to us is that it is translated 2 units up the vertical axis to get its starting position

What we are saying in essence is that the graph of f(x) and g(x) are similar, but f(x) was formed as a result of applying some transformation to g(x)

The transformation applied on f(x) is that it was moved 2 units upwards from g(x)

Since the translation is in a positive direction

Since the graph was moved up, it means that we added to the output of the graph

So the equation becomes;

f(x) = x^4-x^2+ 2

A triangle can not have three sides whose lengths are 3.2 cm 5.3 cm 9.4 cm

We know that the triangle inequality theorem states that for any triangle the sum of any two sides of a triangle is greater than or equal to the third side.

Here, we have been given the three measurements.

Let a = 3.2 cm, b =  5.3 cm and c = 9.4 cm

Consider the sum of sides a and b,

a + b

= 3.2 + 5.3

= 8.5cm

< 9.4

= c

i.e., a + b < c

Acctording to triangle inequality theorem, a, b, c can not be the sides of triangle, as the sum of two sides that measure 3.2 cm and 5.3 cm is not greater than or equal to the third side which measures 9.4 cm

Step-by-step explanation:

the probability is approximately 0.963 (rounded to three decimal places).

What is Probability?

Probability is a branch of mathematics concerned with numerical descriptions of how likely an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates a certainty

To calculate the probability that the outcome of at least two of the three dice will be less than or equal to 4, we can consider the complementary event and subtract it from 1.

The complementary event is that the outcome of all three dice is greater than 4. Since each die has 6 possible outcomes (numbers 1 to 6), the probability of a single die showing a number greater than 4 is (6 - 4)/6 = 2/6 = 1/3.

Since the rolls of the three dice are independent events, we can multiply the probabilities together:

P(all dice > 4) = (1/3) * (1/3) * (1/3) = 1/27

Therefore, the probability of at least two of the dice showing a number less than or equal to 4 is 1 - 1/27 = 26/27.

As a decimal, the probability is approximately 0.963 (rounded to three decimal places).

The reasoning behind this calculation is that we calculate the probability of the complementary event (all dice greater than 4) and subtract it from 1 to obtain the desired probability.

To calculate the total charge within the cylinder with dimensions r=1.5 and h=3, we use the potential function V = 5r + 4 cos Ø in cylindrical coordinates.

The total charge can be obtained by integrating the charge density over the volume of the cylinder.

The potential V within the cylinder is given by V = 5r + 4 cos Ø, where r represents the radial distance from the axis of the cylinder and Ø represents the angle in the cylindrical coordinate system. To calculate the total charge within the cylinder, we need to integrate the charge density over its volume.

The charge density ρ can be related to the potential by ρ = -∇²V, where ∇² is the Laplacian operator. In cylindrical coordinates, the Laplacian operator takes the form:

∇² = (1/r) ∂/∂r (r ∂/∂r) + (1/r²) ∂²/∂ز + ∂²/∂z²

Since the potential function V does not depend on the z coordinate, the Laplacian reduces to:

∇² = (1/r) ∂/∂r (r ∂/∂r) + (1/r²) ∂²/∂ز

Applying this operator to the potential function V, we find:

∇²V = (1/r) ∂/∂r (r ∂V/∂r) + (1/r²) ∂²V/∂ز

To find the charge density, we substitute this expression into ρ = -∇²V:

ρ = -(1/r) ∂/∂r (r ∂V/∂r) - (1/r²) ∂²V/∂ز

To calculate the total charge, we integrate the charge density ρ over the volume of the cylinder:

Q = ∫∫∫ ρ dV = ∫∫∫ -(1/r) ∂/∂r (r ∂V/∂r) - (1/r²) ∂²V/∂ز dV

The integration is performed over the cylindrical coordinates r, Ø, and z, with appropriate limits. Evaluating this integral will give us the total charge within the cylinder.

Based on the given data from the crossover trial comparing two pain relievers (drugs A and B), we can conclude that there is evidence to suggest that the mean pain level is higher with drug B.

The appropriate null and alternate hypotheses are:

Null hypothesis (H0): μ1 = μ2 (There is no difference in the mean pain level between drug A and drug B)

Alternate hypothesis (H1): μ1 < μ2 (The mean pain level is higher with drug B)

To compute the P-value using the TI-84 Plus calculator, we need to perform a paired t-test on the data. By calculating the t-statistic for the paired differences and degrees of freedom, we can obtain the P-value associated with the observed difference. Using the P-value method, the obtained P-value is compared to the significance level (α = 0.10) to make a decision.

If the computed P-value is less than the significance level (0.10), we reject the null hypothesis. This indicates that there is sufficient evidence to support the alternative hypothesis, suggesting that the mean pain level is indeed higher with drug B.

Based on the results of the analysis, we can conclude that there is evidence to suggest that the mean pain level is more with drug B compared to drug A. However, it's important to note that this conclusion is based on the given data and the assumptions made during the analysis. Further studies with larger sample sizes and rigorous experimental designs may be needed to confirm these findings.

Sentence Fram: I found x-intercept by substitute y by 0 and I found y-intercept by substitute x by 0

x-intercept = (6, 0), y-intercept = (0, -3) ⇒ C

Step-by-step explanation:

∵ The equation of the graph is 6x - 12y = 36

→ Equate y by 0 to find x

∵ y = 0

∴ 6x - 12(0) = 36

∴ 6x - 0 = 36

∴ 6x = 36

→ Divide both sides by 6 to find x

∴ x = 6

∴ The x-intercept = (6, 0)

→ Equate x by 0 to find y

∵ x = 0

∴ 6(0) - 12y = 36

∴ 0 - 12y = 36

∴ -12y = 36

→ Divide both sides by -12 to find y

∴ y = -3

∴ The y-intercept = (0, -3)

∴ Sentence Fram: I found x-intercept by substitute y by 0 and I found

   y-intercept by substitute x by 0

∴ x-intercept = (6, 0), y-intercept = (0, -3)
