Answer:

It depends on the cost of grapes.

Step-by-step explanation:

Half of 12 is 6, so if each pack of grapes cost 6 or less, she can buy a pack of green and red grapes.

The equation that Deondra can use to graph the line showing different amounts of green and red grapes she can buy for $12 is :

ax   +   by    =    12

Let the number of green grapes be a

Let the cost of one green grape be x

Let the number of red grapes be b

Let the cost of one red grape be y

The total cost of green and red grapes = $12

The equation representing the illustration will be of the form:

(Number of green grapes)(Cost of 1 green grape) +

(Number of red grapes)(cost of 1 red grape)  =  Total cost

The equation that Deondra can use to graph the line showing different amounts of green and red grapes she can buy for $12 is therefore:

ax   +   by    =    12

Step-by-step explanation:

the square root of 64 is 8ft

The correct choice is c) y=x+2. After substituting the given x value into each equation, we find that only option c, y = x + 2, matches the given parametric equations.

The given parametric equations are x = -4t and y = -4t + 2.

Let's examine each option by substituting the value of x (-4t) into the equation.

For option a, y = x - 2, substituting x = -4t gives us y = -4t - 2. This equation does not match the given y = -4t + 2, so option a is not the correct choice.

For option b, y = x^2 + 2, substituting x = -4t yields y = (-4t)^2 + 2, which simplifies to y = 16t^2 + 2. This equation does not match the given y = -4t + 2, so option b is also not the correct choice.

For option c, y = x + 2, substituting x = -4t gives us y = -4t + 2. This equation matches the given y = -4t + 2, confirming that option c is the correct choice.

Finally, for option d, y = 2x + 1, substituting x = -4t yields y = 2(-4t) + 1, which simplifies to y = -8t + 1. This equation does not match the given y = -4t + 2, so option d is not the correct choice.

Therefore, the correct answer is option c)  y=x+2.

Answer:

The function graphed below is \(x = y^{2} - 2\) or \(y = \pm \sqrt{x+2}\).

Step-by-step explanation:

The graph represents a second order polynomial function (a parabola), whose axis of symmetry is the x-axis and whose form is presented as follows:

\(x - h = C\cdot (y-k)^{2}\)

Where:

\(x\), \(y\) - Dependent and independent variable, dimensionless.

\(h\), \(k\) - Horizontal and vertical components of the vertex, dimensionless.

\(C\) - Vertex constant, dimensionless. If \(C > 0\), then vertex is an absolute minimum, otherwise it is an absolute maximum.

After a quick observation, the following conclusions are done:

1) Vertex is an absolute minimum (\(C > 0\)) and located at (-2, 0).

2) Parabola pass through (2, 2).

Then, the value of the vertex constant is obtained after replacing all known values on expression prior algebraic handling: (\(x = 2\), \(y = 2\), \(h = -2\), \(k = 0\))

\(2+2 = C\cdot (2-0)^{2}\)

\(4 = 4\cdot C\)

\(C = 1\)

The function is:

\(x = -2 + 1\cdot y^{2}\)

\(x = y^{2}-2\)

The inverse function of this expression is \(y = \pm \sqrt{x+2}\)

The function graphed below is \(x = y^{2} - 2\) or \(y = \pm \sqrt{x+2}\).

Option B. $9,255.75, Only option (b) includes a value close to $1,000, which is the present value of the infinite stream of

To find the present value of an infinite stream of cash flows, we can use the formula:

PV = CF / r

where PV is the present value, CF is the cash flow per period, and r is the interest rate per period.

In this case, CF = $100 (received at the end of each year forever) and r = 10%.

Plugging in the numbers, we get:

PV = $100 / 0.10 = $1,000

So the present value of the infinite stream of cash flows is $1,000.

However, we need to adjust for the fact that the cash flows are received at the end of each year, not at the beginning. To do this, we can use the formula:

PV = CF / (r - g)

where g is the growth rate of the cash flows, which in this case is 0 (since the cash flows are constant).

Plugging in the numbers, we get:

PV = $100 / (0.10 - 0) = $1,000

So the present value of the infinite stream of cash flows received at the end of each year is also $1,000.

Therefore, the answer must include the present value of an infinite stream of cash flows. Only option (b) includes a value close to $1,000, which is the present value of the infinite stream of cash flows.

Answer:

We have the proportion: 8/10 = 100/y

We can solve for y by cross-multiplying.

That is, 8y = 100 * 10 Simplifying the right-hand side, 8y = 1000

Dividing both sides by 8 to solve for y, y = 125

Hence, the value of y is 125.

Finally, we have the expression: y = √80We can simplify this expression by factoring 80 into its prime factors:80 = 2 * 2 * 2 * 2 * 5

Taking the square root of 2 * 2 * 2 * 2, we have:√(2 * 2 * 2 * 2) = 2 * 2 = 4

Therefore, y = 4√5The value of y is 4√5.

Step-by-step explanation:

The RMS (Root Mean Square) value of a sine wave represents the equivalent DC voltage that would produce the same amount of power in a resistive load. However, the heat produced in a resistor is directly proportional to the square of the current passing through it (according to Joule's Law). In the case of an AC waveform, the current continuously changes direction, resulting in a time-varying power dissipation. Therefore, comparing the RMS value of an AC waveform to a DC voltage is not directly applicable in terms of heat produced in a resistor.

The estimated simple linear regression coefficient, β, is a measure of the strength of the relationship between the predictor and response variables,

The estimated simple linear regression coefficient, β, measures the strength of a linear relationship between the predicting and response variables. It determines how much the response variable (dependent variable) changes for every unit increase in the predictor variable (independent variable).

For example, if the regression coefficient is 2, it means that for every one unit increase in the predictor variable, the response variable increases by 2 units.

Linear regression is a statistical technique used to model the relationship between a dependent variable and one or more independent variables. It is used to identify the linear relationship between the two variables and to predict the values of the dependent variable based on the values of the independent variable.

The regression coefficient is used to measure the strength of this relationship, and is calculated using a variety of statistical techniques, such as the method of least squares. The coefficient is an important tool in data analysis, as it helps researchers to identify trends and patterns in the data.

In conclusion, the estimated simple linear regression coefficient, β, is a measure of the strength of the relationship between the predictor and response variables, and is an important tool in statistical analysis.

The probability that a randomly selected bird is a parakeet given that it is green is 54.1%.

The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Probability is a measure of the likelihood that an event will occur or the likelihood that something will happen. The likelihood that the coin will land with the heads side up after being tossed into the air is described using the word probability.

Let,

A be the  Parakee

B be the Green

To find the probability that a randomly selected bird is a parakeet given that it is green.

That means P(A|B)

The number of birds that are both parakeet and green is n(A∩B)=20

The number of birds that are green is n(B)=37

Hence, using the conditional probability formula P(A∣B) = \(\dfrac{n(A\bigcap B}{n(B)}\)

P(A∣B) = \(\dfrac{n(A\bigcap B)}{n(B)}\)

P(A∣B) = 20/37

P(A∣B) = 20/37 × 100%

P(A∣B) = 54.1%

Thus, the probability that a randomly selected bird is a parakeet given that it is green is 54.1%.

Circumference of a circle with equation \((x+2)^{2}+(y-3)^{2}\) = 9 is 6pi.

To find the circumference of a circle with equation  \((x+2)^{2}+(y-3)^{2}\) = 9, we first need to identify its radius, which is the square root of the constant term 9. The radius is therefore 3 units.

The formula for the circumference of a circle is C = 2πr, where C is the circumference, r is the radius, and π is a mathematical constant approximately equal to 3.14159.

Using this formula, we can calculate the circumference of the given circle as:

C = 2πr = 2π(3) = 6π

Therefore, the circumference of the circle with equation  \((x+2)^{2}+(y-3)^{2}\) = 9 is 6π units.

It's important to note that the circumference of a circle is the distance around the edge of the circle. It is an important parameter for many applications in geometry, physics, and engineering, among others.

In most of the cases airlines charges a fees for baggage weigh in excess of 50 pounds. Then about 94.06% passengers incur this fees.

When the distribution is normal, we use the z-score formula.

In a set with mean and standard deviation , the z-score of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Given That,

Mean (μ) = 45 pounds and Standard Deviation (σ) = 3.2

This means that μ = 46 , σ = 3.2

Since, Most airlines charges a fee for baggage that weigh in excess of 50 pound.

Then, As a proportion this is 1 subtracted by the P - value of Z when

X =50. So,

      Z = X - μ / σ

⇒ Z = 50 -45/ 3.2

⇒ Z = 5/3.2

⇒ Z = 1.56

when Z = 1.56 has a P- value of 0.9406

Now, 0.9406 × 100%
