HELP ! find the unit price for a 16-oz, jar of peanut butter for $3.28

Step-by-step explanation:

To find the price of one tire patch, you could use the equation:

4x = 22.2 + 1.9

which simplifies to:

4x = 24.1

Then divide both sides by 4 to isolate x:

x = 6.025

So the equation that applies here is:

4x = 22.2 + 1.9

The sampling method described in the question is called "quota sampling."

Quota sampling is a non-probability sampling technique in which researchers select participants based on pre-determined quotas or characteristics, such as age or gender. In this case, the researchers are selecting participants between the ages of 20 and 40.

However, this method may not be representative of the entire population as it does not guarantee that all subgroups within the population have an equal chance of being selected. Therefore, the results may be biased and not accurately reflect the opinions of the entire population.

Therefore, it is important to consider the limitations of quota sampling when interpreting the results

2)If the trend continues,  a student expect to pay for room and board in 2017 is $7862.35 .

What is exponential function?

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth.

Here we need to use exponential function formula to find the cost function . Then,

=> [tex]f(x)=a(1+r)^t[/tex]

Where a is cost for room in 2000 and r is rate of change.

Then model the cost of room and board C after t years since 2000, we can use the formula:

=> [tex]C = 4,291(1 + 0.0315)^t[/tex]

where 0.0315 represents the annual increase of 3.15% expressed as a decimal.

Now we have to find the cost of room and board in 2017, we need to substitute t = 17 (since 2017 is 17 years after 2000) into the function and round the result to the nearest hundredth.

So,[tex]C = 4,291\times(1 + 0.0315)^{17}[/tex]

=>C = 7,862.35

Therefore, a student would expect to pay approximately $7862.35 for room and board in 2017 if the trend continued.

Flow rate =[tex]V_{new} / time = (3.5 * V_{old}) / time = (3.5 * 576,000) / 84 = 23,333[/tex] gallons per hour (rounded to the nearest gallon) will be circulated.

What is meant by rate?

In general, a rate is a measure of how quickly something changes over time or with respect to some other quantity. It is typically expressed as a ratio of two quantities, where the numerator represents the amount of change and the denominator represents the time or other quantity over which the change occurs.

If the new exhibit is 3 1/2 times larger than the old one, then its volume is:

[tex]V_{new} = 3.5 * V_{old[/tex]

We know that in the old exhibit, 576,000 gallons of water circulated over 24 hours. Therefore, the flow rate of water in gallons per hour is:

576,000 gallons / 24 hours = 24,000 gallons per hour

To find the flow rate in the new exhibit, we need to divide the total volume of water by the number of hours. Since we want the flow rate in gallons per hour, we can write:

Flow rate = [tex]V_{new[/tex] / time

Plugging in the values we have:

Flow rate = (3.5 * [tex]V_{old[/tex]) / time

We don't know the time yet, but we do know that the flow rate should be the same as in the old exhibit, which was 24,000 gallons per hour. So we can set up an equation:

24,000 = (3.5 * [tex]V_{old[/tex]) / time

To solve for time, we can multiply both sides by time:

24,000 * time = 3.5 * [tex]V_{old[/tex]

Then we can divide both sides by 24,000:

time = (3.5 * [tex]V_{old[/tex]) / 24,000

Plugging in [tex]V_{old[/tex] = 576,000, we get:

time = (3.5 * 576,000) / 24,000 = 84 hours

Therefore, in the new exhibit, 3.5 times larger than the old one, the flow rate of water in gallons per hour will be:

[tex]Flow rate = V_{new} / time = (3.5 * V_{old}) / time = (3.5 * 576,000) / 84 = 23,333[/tex]gallons per hour (rounded to the nearest gallon).

Answer:

To find out how many gallons per hour will be circulated in the new exhibit, we need to first determine the volume of the old exhibit. Given that 576,000 gallons of water circulated through the old tank over 24 hours, we can calculate the amount of water circulated per hour.

To do this, we divide the total gallons by the number of hours:

576,000 gallons / 24 hours = 24,000 gallons per hour

Now, we know that the new exhibit is 3 1/2 times larger than the old one. To find the volume of the new exhibit, we multiply the volume of the old exhibit by 3 1/2.

Let's assume the volume of the old exhibit is x gallons.

The volume of the new exhibit is 3 1/2 times larger than the old one, so the volume of the new exhibit is 3 1/2 * x.

To calculate the new volume, we need to convert the mixed fraction 3 1/2 into an improper fraction. It equals 7/2.

So, the volume of the new exhibit is 7/2 * x.

Now, we can determine the amount of water circulated per hour in the new exhibit.

To find this, we multiply the volume of the new exhibit by the rate of circulation per hour in the old exhibit (24,000 gallons/hour):

(7/2 * x) * 24,000 gallons/hour = (7 * 24,000 * x) / 2 gallons/hour = 168,000x gallons/hour

Therefore, the number of gallons per hour that will be circulated in the new exhibit is 168,000x, where x represents the volume of the old exhibit.

Please note that the actual value of x (the volume of the old exhibit) is not given in the question, so we can't determine the exact number of gallons per hour. However, we can express it as a multiple of the volume of the old exhibit.

Note that given the perimeter of the Rhombus above, KN will be 35.03 inches

Since JKLM is a rhombus, all sides have the same length. Let's call this length "x".

Also, since JL and KM are diagonals of the rhombus, they bisect each other at point N. This means that JN = NL and KN = NM.

We know that JN = 16 inches, and we need to find KN. To do this, we need to first find x, the length of the sides.

The perimeter of the rhombus is 72 inches, so we can write:

4x = 72

Dividing both sides by 4, we get:

x = 18

Now we can use the Pythagorean theorem to find NM (which is equal to KN):

(NM)² = (JN)² + (JM)²

We know that JN = 16, and we can find JM using the fact that JL and KM are perpendicular bisectors of each other:

JM = √[(2x)² - x²] = sqrt(3x²) = x √(3)

Substituting x = 18 and simplifying, we get:

(NM)² = 16² + (18 √(3))²

(NM)² = 256 + 972

(NM)² = 1228

NM = √(1228) = 35.03

Therefore, KN is approximately 35.0 inches (to the nearest tenth).

Answer:

Los dos números naturales son 12 y 58.

Step-by-step explanation:

Llamemos al número más pequeño "x" y al número más grande "y".

Del problema sabemos que:

x + y = 70 (ya que la suma de los dos números naturales es 70)

Cuando el número mayor se divide por el número menor, el cociente es 4 con un resto de 10. Esto se puede escribir como:

y = 4x + 10 (ya que 4 es el cociente y 10 es el resto)

Ahora podemos sustituir la segunda ecuación en la primera ecuación:

x + (4x + 10) = 70

Simplificando esta ecuación, obtenemos:

5x + 10 = 70

Restando 10 de ambos lados, obtenemos:

5x = 60

Dividiendo ambos lados por 5, obtenemos:

x = 12

Ahora que conocemos x, podemos volver a sustituirlo en una de las ecuaciones anteriores para encontrar y:

y = 4x + 10 = 4(12) + 10 = 58

Por lo tanto, los dos números naturales son 12 y 58.

The probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.

To solve this problem, we can use the Central Limit Theorem, which states that the distribution of sample means is approximately normal for large sample sizes.

First, we need to calculate the standard error of the mean (SEM) using the formula

SEM = standard deviation / sqrt(sample size)

SEM = 29.5 / sqrt(45) = 4.4

Next, we can standardize the sample mean using the formula

z = (x - μ) / SEM

where x is the sample mean, μ is the population mean, and SEM is the standard error of the mean.

For the lower limit, we have

z = (185.7 - 193.2) / 4.4 = -1.70

For the upper limit, we have

z = (206.5 - 193.2) / 4.4 = 3.02

We can use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.

The probability of z being between -1.70 and 3.02 is approximately 0.9429 or 94%. Therefore, the probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.

The estimated relationship may not hold for all levels of TV advertising, and there may be non-linearities or interactions with other variables that should be taken into account in a more sophisticated model.

What is the interpretation of this relationship?

To develop an estimated regression equation to estimate weekly gross revenue with the amount of television advertising as the independent variable, we would need a dataset that includes information on both variables. Assuming we have such a dataset, we could use linear regression to estimate the relationship between the two variables.

The estimated regression equation would take the form:

Weekly Gross Revenue = [tex]b_0 + b_1[/tex]×Amount of TV Advertising + error

where [tex]b_0[/tex] is the intercept (the value of weekly gross revenue when the amount of TV advertising is zero), [tex]b_1[/tex] is the slope (the estimated increase in weekly gross revenue associated with a one unit increase in TV advertising), and error represents the random variation in the relationship between the two variables that is not explained by the model.

The interpretation of the relationship between weekly gross revenue and amount of TV advertising would depend on the sign and magnitude of the slope coefficient

[tex](b_1)[/tex]. If [tex]b_1[/tex] is positive, it would suggest that an increase in TV advertising is associated with an increase in weekly gross revenue. The magnitude of [tex]b_1[/tex] would indicate the strength of this relationship - a larger positive value of[tex]b_1[/tex] would indicate a stronger relationship between TV advertising and weekly gross revenue.

If [tex]b_1[/tex] is negative, it would suggest that an increase in TV advertising is associated with a decrease in weekly gross revenue. This could occur if the advertising is perceived as irritating or offensive to viewers, leading them to avoid the advertised product or service.

It is important to note that correlation does not imply causation, and there may be other factors that affect weekly gross revenue that are not captured in the model.

a. The probability that the top-selling Red and Voss tire wears out before 60,000 miles can be found by calculating the Z-score and using a standard normal distribution table. The Z-score formula is: Z = (X - μ) / σ, where X is the distance (60,000 miles), μ is the mean (71,000 miles), and σ is the standard deviation (5,000 miles).

Z = (60,000 - 71,000) / 5,000 = -11,000 / 5,000 = -2.2. Using a standard normal distribution table, the probability is approximately 0.0139 or 1.39%.

A triangle is a basic geometrical shape that is formed by connecting three non-collinear points in a plane using straight line segments. The three points are called the vertices of the triangle, and the line segments connecting them are called the sides. The angles formed between the sides of a triangle are also an important characteristic of the triangle. Triangles come in many different shapes and sizes, and they have many interesting properties and applications in mathematics, science, engineering, and other fields.

The final balance of the checking account after these transactions would be $375 - 2x. Note that we do not have information about the actual values of x, so we cannot determine the final balance precisely.

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

The initial balance of the checking account is $350.

If the customer makes two withdrawals, one $50 more than the other, let's assume the smaller withdrawal amount is x. Then, the larger withdrawal amount will be x + $50.

So, the new balance of the checking account after these two withdrawals would be:

$350 - x - (x + $50) = $350 - 2x - $50 = $300 - 2x

After this, the customer makes a deposit of $75, which would increase the balance of the checking account to:

$300 - 2x + $75 = $375 - 2x

The measure of IJ is 29, when IJ is dilated by a scale factor of 2 to form I' J', and I' J' measures 58. Geometric figures in two or three dimensions can be expanded and contracted using dilation mathematics.

Dilation refers to the change in size without a change in shape of an object. The scale factor may also cause the object's size to either increase or decrease.

Dilation is hence the process of resizing or altering an object. It is a transformation that makes the objects smaller or larger by applying the provided scale factor. It is a transformation that makes the objects smaller or larger by applying the provided scale factor. The pre-image is the original figure, while the image is the new figure created as a result of dilation. Dilation comes in two varieties:

As an object experiences expansion, its size expands.

Contraction is the process of a thing getting smaller.

Given:

I'J' is IJ with the scale factor of 2.

so (IJ) × 2= (I'J)

(IJ) × 2 = 58

58 ÷ 2 = 29

5 \tan x &= -4 \

\tan x &= \frac{-4}{5}

\end{align*}

Therefore, the value of $\tan x$ is $\boxed{\frac{-4}{5}}$.

Polynomial expressions of [tex]2^{nd}[/tex] degree with one unknown (only [tex]x[/tex]) have [tex]2[/tex] roots. We use the formula below to determine these roots;

This formula is valid for equations of the form [tex]ax^2+bx+c[/tex]. We can convert the equation given in the question into this format to get the result;

Hence, the value of [tex]a[/tex]: [tex]8[/tex],

the value of [tex]b[/tex]: [tex]16[/tex],

Rectangle ABCD was translated 8 units left and then 7 units down.

We can see vertex A(2,4) of rectangle ABCD moves to A"(-6,-3), in a way that A translated 8 units left (-8)and 7 units down(-7) to A".

A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.

Vertex is a point on a polygon where the sides or edges of the object meet or where two rays or line segments meet. The plural of a vertex is vertices.

A line segment is a part of a straight line that is bounded by two distinct end points, and contains every point on the line that is between its endpoints. The length of a line segment is given by the Euclidean distance between its endpoints.

that is (2-8,4-7)=(-6,-3)

Similarly the other vertices of rectangle ABCD moves to form rectangle A"B"C"D"

B (2,2) → B" (-6,-5)

C (6,2) → C" (-2,-5)

D(6,4) → D" (-2,-3)

Answer:

m = 5

n = 2

c = 7

Step-by-step explanation:

Use the property of degrees (when dividing two same based numbers with different degree indicators, the degree indicators are subtracted)

[tex] \frac{ {9}^{ - 3} }{ {9}^{2} } = \frac{1}{ {9}^{m} } [/tex]

[tex] {9}^{ - 3 - 2} = {9}^{ - 5} [/tex]

[tex] {9}^{ - 5} = \frac{1}{ {9}^{m} } [/tex]

If the degree indicator is negative, the number is written as a fraction (1 in the numerator) and the degree indicator is raised to the denominator with a positive sign:

m = 5

.

[tex] \frac{ {x}^{ - 4} }{ {x}^{ - 6} } = {x}^{n} [/tex]

[tex] {x}^{ - 4 - ( - 6) } = {x}^{ - 4 + 6} = {x}^{2} [/tex]

n = 2

.

[tex] \frac{ ({ - 11})^{7} }{ ( { - 11})^{0} } = ( { - 11})^{c} [/tex]

Raising any number to the zero power makes it one

[tex] \frac{ ({ - 11})^{7} }{1} = ({ - 11})^{c} [/tex]

When dividing by 1, the number does not change

[tex]( { - 11})^{7} = ({ - 11})^{c} [/tex]

c = 7
