(a) When performing an ANOVA with the data the alternative hypothesis is at least two of the restaurants have different mean delivery times.

(b)75.8

Analysis of variance. or ANOVA, is a statistical method that separate observed variance data into different components to use for additional tests. A one way ANOVA is used for three or more groups of data, to gain information about the relationship between the dependent and independent variables.

The ANOVA table shows how the sum of squares are distributed according to source of variation, and hence the mean sum of squares.

It is given that a pizza lover wants to compare the average delivery times.

Therefore the null hypothesis and alternate hypothesis implies that,

H₀ =  all restaurants have equal mean delivery time

Hₐ = at least two restaurants have different two deliveries

Hence the alternate hypothesis for performing an ANOVA with the data is at least two of the restaurants have different mean delivery times.

The alternate hypothesis (Hₐ) defines that there is a statistically important relationship between two variables. Whereas null hypothesis states that is no statistical relationship between the two variables.

Answer: Y=6x2−30x−84

Step-by-step explanation:

Answer:

See below, please.

Step-by-step explanation:

The quadratic function in standard form would be

Y = 6x^2 - 24x - 84

To convert the quadratic function from factored form to standard form, we use the distributive property to multiply out the factors

Y = 6(x-7)(x+2)

Y = 6(x^2 + 2x - 7x - 14)

Y = 6(x^2 - 5x - 14)

Then, we simplify the equation by multiplying out the coefficient of x^2 and combining like terms

Y = 6x^2 - 30x - 84

Finally, we write the quadratic function in standard form by arranging the terms in descending order of degree

Y = 6x^2 - 30x - 84

It should be 87% cz 87/100

The value that represents the Inter-Quartile Range of data is 26.

Option A is the correct answer.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

From the boxplot, we can see that,

Third quartile = 46

First quartile = 20

Now,

Interquartile range

= Third quartile - First quartile

= 46 - 20

Step-by-step explanation:

The maximum profit is $5000, which can be achieved by planting 50 acres of corn and 0 acres of wheat.

This is a linear programming problem that can be solved using the simplex method. We can define two decision variables

x1: the number of acres of wheat to be planted

x2: the number of acres of corn to be planted

The objective is to maximize the profit, which can be expressed as

maximize 80x1 + 100x2

The constraints are:

4x1 + 16x2 <= 800 (limit on labor hours)

20x1 + 40x2 <= 2400 (limit on capital)

x1, x2 >= 0 (non-negativity constraint)

We can rewrite the constraints in the form of inequalities:

x2 <= 50 - 0.25x1

x2 <= 60 - 0.5x1

x1, x2 >= 0

The first two constraints are derived by dividing the labor and capital constraints by the respective coefficients of x2 and x1.

The feasible region is bounded by the x-axis, y-axis, and the two lines given by the above inequalities. It is a convex polygon with vertices at (0,0), (0,50), (20,30), and (40,0).

To find the maximum profit, we need to evaluate the objective function at each vertex of the feasible region and choose the one with the highest value. This can be done as follows

At (0,0), the profit is 0.

At (0,50), the profit is 5000.

At (20,30), the profit is 3400.

At (40,0), the profit is 3200.

Therefore, the maximum profit is $5000

The simplified expression is given by (x² - 3x - 3) / ((x + 3)(x - 2)(x - 4)).

To simplify this expression, we need to find a common denominator for the two fractions and then combine them. To do this, we need to factor the denominators of both fractions.

Let's start with the first fraction's denominator:

x² + x - 6

We need to find two numbers that multiply to -6 and add to +1. These numbers are +3 and -2. Therefore, we can write:

x² + x - 6 = (x + 3)(x - 2)

Now let's factor the second fraction's denominator:

x² - 6x + 8

We need to find two numbers that multiply to 8 and add to -6. These numbers are -2 and -4. Therefore, we can write:

x² - 6x + 8 = (x - 2)(x - 4)

Now we can rewrite the original expression with a common denominator:

(x(x - 2) - (1)(x + 3)) / ((x + 3)(x - 2)(x - 4))

Next, we can simplify the numerator:

(x² - 2x - x - 3) / ((x + 3)(x - 2)(x - 4))

(x² - 3x - 3) / ((x + 3)(x - 2)(x - 4))

Finally, we can't simplify this expression any further. Therefore, the simplified expression is:

(x² - 3x - 3) / ((x + 3)(x - 2)(x - 4))

Step-by-step explanation:

RU is a median.

so, U is right in the middle between S and T.

and therefore, SU = UT.

3x + 5 = 5x - 7

12 = 2x

x = 6

so, SU = UT = 3×6 + 5 = 18 + 5 = 23 in.

therefore, ST = 2×23 = 46 in.

furthermore, the centroid splits every median with the ratio 2/1.

so, RQ = 2×QU.

RQ = 5 IN, therefore QU = RQ/2 = 5/2 = 2.5 in.

and RU is then 5 + 2.5 = 7.5 in.

for QV we need to go the other way around.

we know SV = 12 in.

and Q splits it also in the ratio 2/1.

that means we deal with 2+1=3 parts of the median.

SQ gets 2 of these parts, and QV gets 1 of these parts.

12/3 = 4 in power unit.

so,

SQ = 2×4 = 8 in.

QV = 1×4 = 4 in.

I believe your teacher made a mistake with the SU and UT definitions.

because ST is almost 4 times the length of the median SV.

and RU is even shorter than SV.

so, as SU = 23 in, V must be far left of U. and R must be left of U but right of V !

The explicit solution to the IVP is:

y = (1-x) * 2e^(x^3/3-1/3) or y = (x-1) * (-2e^(x^3/3-1/3))

To find an explicit solution to the IVP:

x² dy/dx = y - xy, y(-1) = -1

We can first write the equation in standard form by dividing both sides by y-xy:

x^2 dy/dx = y(1-x)

Next, we can separate the variables by dividing both sides by y(1-x) and multiplying both sides by dx:

dy / (y(1-x)) = x^2 dx

Now we can integrate both sides. On the left side, we can use partial fractions to break the integrand into two parts:

1/(y(1-x)) = A/y + B/(1-x)

where A and B are constants to be determined. Multiplying both sides by y(1-x) gives:

1 = A(1-x) + By

Substituting x=0 and x=1, we get:

A = 1 and B = -1

Therefore:

1/(y(1-x)) = 1/y - 1/(1-x)

Substituting this into the integral, we get:

∫[1/y - 1/(1-x)]dy = ∫x^2dx

Integrating both sides, we get:

ln|y| - ln|1-x| = x^3/3 + C

where C is a constant of integration.

Simplifying, we get:

ln|y/(1-x)| = x^3/3 + C

Using the initial condition y(-1) = -1, we can solve for C:

ln|-1/(1-(-1))| = (-1)^3/3 + C

ln|-1/2| = -1/3 + C

C = ln(2) - 1/3

Therefore, the explicit solution to the IVP is:

ln|y/(1-x)| = x^3/3 + ln(2) - 1/3

Taking the exponential of both sides, we get:

|y/(1-x)| = e^(x^3/3) * e^(ln(2)-1/3)

= 2e^(x^3/3-1/3)

Simplifying, we get two solutions:

y/(1-x) = 2e^(x^3/3-1/3) or y/(x-1) = -2e^(x^3/3-1/3)

Therefore, the explicit solution to the IVP is:

y = (1-x) * 2e^(x^3/3-1/3) or y = (x-1) * (-2e^(x^3/3-1/3))

The carbon cycle is a natural process that involves the movement of carbon atoms between the atmosphere, organisms, rocks, sediments, and the ocean.

The carbon cycle is a crucial process for maintaining the balance of carbon in the Earth's ecosystems. Carbon dioxide (CO2) is taken up by plants during photosynthesis, converting it into organic carbon compounds that are stored in plant tissues. When plants die and decompose, or when animals respire or decompose, carbon is released back into the atmosphere as CO2. Additionally, carbon can be stored in rocks and sediments over long periods of time.

Deforestation, the clearing of forests on a large scale, can significantly disrupt the carbon cycle. When forests are cut down, the stored carbon in trees and vegetation is released into the atmosphere as CO2 through the process of decomposition or burning. This contributes to increased greenhouse gas emissions and can contribute to climate change.

Furthermore, deforestation reduces the number of trees available to absorb CO2 through photosynthesis, leading to decreased carbon uptake from the atmosphere. The loss of forests also means the loss of carbon sinks, as trees are natural carbon storage systems. Without these sinks, more carbon remains in the atmosphere, further exacerbating the greenhouse effect.

In addition to these changes, deforestation can also impact the water cycle, which in turn affects the carbon cycle. Trees play a vital role in regulating water flow and moisture levels in ecosystems. When forests are removed, there is a higher risk of soil erosion and decreased water retention. These changes can affect the growth and survival of plants, ultimately impacting carbon uptake and storage.

In summary, deforestation disrupts the carbon cycle by releasing stored carbon into the atmosphere, reducing carbon uptake, and altering carbon storage patterns. These changes contribute to increased greenhouse gas emissions, climate change, and overall environmental imbalance.

The type of sampling used by the BLS (Bureau of Labor Statistics) for its National Compensation Survey, where employers are divided by size in the second stage of sampling, is known as stratified sampling.

Stratified sampling involves dividing the population into subgroups or strata based on certain characteristics or criteria. In this case, the BLS divides the employers into different size categories. Within each stratum, a sample is then randomly selected to represent that specific subgroup. This approach allows for a more precise estimation of employment costs within each size category. By using stratified sampling, the BLS ensures that the sample is representative of the different employer sizes and allows for more accurate and reliable estimates of employment costs at a national level.

9x = 180 divide both sides by 9

x = 20

The angle represented with 3x - 30 and the angle represented with 2x + 10 are alternate and their measurement is same

Answer:

Step-by-step explanation:

If I'm not mistaken, and I very well could be, this is a calculus problem(?). In order to find the distance without calculus you'd need a point on the given line to use to find the distance in the distance formula. But you don't have a point on the given line, so we can find the shortest distance between the point (1, 4) and the given line using the derivative of the polynomial formed when using the distance formula.

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\) and we have the x and y for x2 (or x1...it doesn't matter which you choose to fill in):

\(d=\sqrt{(1-x)^2+(4-y)^2}\)

but what we find is that we have too many unknowns here, namely, the distance, the x coordinate, and the y coordinate. So we can replace the y coordinate with what y is equal to in terms of the linear equation:

\(d=\sqrt{(1-x)^2+(4-\frac{1}{3}x-3)^2 }\) and simplify:

\(d=\sqrt{(1-x)^2+(7-\frac{1}{3}x)^2 }\)

. No we'll expand each binomial by squaring:

\(d=\sqrt{(1-2x+x^2)+(49-\frac{14}{3}x+\frac{1}{9}x^2) }\)

.  Combining like terms gives us

\(d=\sqrt{\frac{10}{9}x^2-\frac{20}{3}x+50 }\)

The distance between the point (1, 4) and the given line will be at a minimum when the polynomial above is at a minimum. We find the value of x for which the polynomial is at a minimum by finding its derivative, setting the derivative equal to 0, and then solving for x. The derivative of the polynomial is

\(\frac{20}{9}x-\frac{20}{3}\)

Setting equal to 0 and getting rid of the denominators gives us

20x - 60 = 0

Solving for x gives us

20x = 60 and x = 3.

That's the value of x that gives us the shortest distance between (1, 4) and the line y = 1/3x - 3. Sub into the distance formula that x value to find the distance:

\(d=\sqrt{(\frac{10}{9})(3)^2-(\frac{20}{3})(3)+50 }\)
