Answer:

y-intercept : 3

x-intercepts are 1 and 2

Vertex is at (2,-1)

Axis of symmetry is at x = 2

Step-by-step explanation:

See attached graph.

The equation y = x² – 4x + 3 represents a parabola

y-intercept at is at B(0,3); y-intercept is 3

x-intercept points at C(1,0) and D(3,0) so x-intercepts are 1 and 3

The vertex is the lowest point on this parabola (2-1)

Axis of symmetry is a line passing through the vertex and dividing the parabola into two equal halves. This is the vertical line x = 2

According to the question we have our assumption must be false and there are indeed infinitely many primes of the form 4k+3.

To prove that there are infinitely many primes of the form 4k+3, where k is a nonnegative integer, we can use a proof by contradiction. Assume that there are only finitely many primes of this form, say p1, p2, p3, ..., pn.

Consider the number N = 4(p1p2p3...pn) - 1. This number is of the form 4k+3, since the product of primes is also of this form.

Now, any prime factor of N must also be of the form 4k+3, since any prime factor of N cannot be 2 (since N is odd) and it cannot be of the form 4k+1 (since N leaves a remainder of 3 when divided by 4).

However, this contradicts our assumption that p1, p2, p3, ..., pn are the only primes of the form 4k+3, since N is a prime greater than pn and is also of this form.

Therefore, our assumption must be false and there are indeed infinitely many primes of the form 4k+3.

The absolute value of the error in the professor's initial estimate of the mean GPA is 0.14, which is a combination of errors in data acquisition, nonresponse bias, and selection bias. The absolute value of the error in the estimate using the new sample provided by the registrar is 0.12, and the only way to reduce this error is by increasing the sample size.

The professor initially takes a sample of students present on the third day of class to estimate the mean GPA. However, this sample may introduce errors in data acquisition (such as incorrect recording), nonresponse bias (if a student declines to disclose GPA), and selection bias (if certain groups, like honors students on a field trip, are excluded). These errors contribute to the absolute value of the initial error in the estimate, which is 0.14.

To address potential flaws in the sample, the professor decides to use a new sample obtained through simple random sampling. Each student signs a release allowing the registrar to provide their GPAs for computing the sample average. The absolute value of the error in this new estimate is 0.12. This error can only be reduced by increasing the sample size, as a larger sample would better represent the population and reduce sampling variability.

By ensuring a random and representative sample, the professor aims to minimize errors due to data acquisition, nonresponse bias, and selection bias, leading to a more accurate estimate of the mean GPA.

Explanation:

A relation is a function if and only if for each value of x there's only one value of y. In other words, if we find one value of x more than once, the relation is not a function.

Relation A is not a function because x = 2 shows up twice: (2, 5) and (2, 7)

Relation C is not a function because x = 1 shows up three times: (1, 3), (1, 5) and (1, 7)

Relation E is not a function because x = 2 shows up twice: (2, 5) and (2, 1)

Relations B and D have only one time each value of x

When there is an increase in the money supply, the new long-run equilibrium is determined by point B on the aggregate demand and supply model.

In the aggregate demand and supply model, the equilibrium represents the point where aggregate demand (AD) and aggregate supply (AS) intersect, indicating a stable state of the economy. The original equilibrium is represented by point A.

When the money supply increases, it affects the economy in several ways. An increase in the money supply leads to a decrease in interest rates. Lower interest rates encourage borrowing and investment, which in turn stimulates aggregate demand. As a result, the aggregate demand curve shifts to the right.

The shift in aggregate demand causes an increase in both output and prices in the short run. However, in the long run, prices adjust to reflect the increased money supply. As prices rise, the short-run aggregate supply curve shifts to the left until it intersects with the new aggregate demand curve.

The long-run equilibrium is determined by the point where the new aggregate demand curve intersects with the adjusted aggregate supply curve, represented by point B. At this new equilibrium, both output and prices are higher than the original equilibrium (point A).

Answer:

56 cola flavored gumboils

Step-by-step explanation:

Bob's 40 count of gumballs has 16 cola gumballs

Therefore the probability of a gumball being cola based on the sample size of Bob's purchase = 16/40 = 2/5

There are 140 gumballs left in the machine so we can expect that, on an average, 2/5 of them should be cola gumballs

So number of cola gumballs left is expected to be  2/5 x 140 = 56

This is only a prediction based on Bob's sample of 40 cola gumballs

Answer:

The distance between (3, -1) and (0, 3) is 5

Step-by-step explanation:

To determine the width of the border surrounding an inch by inch picture, we need to calculate the difference in area between the picture with the border and the picture alone.

Let's denote the width of the border as "x". The total width of the picture with the border will then be "1 + 2x" (since the border is on both sides of the picture). Similarly, the total length of the picture with the border will be "1 + 2x".

To calculate the area of the picture with the border, we multiply the width and length: (1 + 2x) * (1 + 2x).

The area of the picture alone is 1 * 1 = 1 square inch.

The area of the picture with the border is given by (1 + 2x) * (1 + 2x) - 1.

The question asks for the width of the border, which is the value of "x" that satisfies the equation (1 + 2x) * (1 + 2x) - 1.

Solving this equation will give us the width of the border.

Answer:

Answer:

Juan = 93 years.

Gabe = 31 years.

Catherine = 25 years.

Step-by-step explanation:

Let the age of Juan = J

Let the age of Gabe = G

Let the age of Catherine = C

Translating the word problem into an algebraic equation, we have;

\( J = 3G\) ..........equation 1

\( G = C + 6 \) ........equation 2

\( J + G + C = 149 \) ........equation 3

We would solve the linear equations by using the substitution method;

Substituting equation 2 into equation 1;

\( J = 3(C + 6)\)

\( J = 3C + 18\) ........equation 4

Substituting equation 2 and equation 4 into equation 3;

\( (3C + 18) + (C + 6) + C = 149 \)

Simplifying the equation, we have;

\( 5C + 24 = 149\)

\( 5C = 149 - 24\)

\( 5C = 125\)

\( C = \frac {125}{5}\)

C = 25 years.

To find G; from equation 2

\( G = C + 6\)

Substituting the value of "C" into equation 2, we have;

\( G = 25 + 6\)

G = 31 years.

To find J; from equation 1

\( J = 3G \)

Substituting the value of "G" into equation 1, we have;

\( J = 3 * 31\)

J = 93 years.

Therefore, Juan is 93 years old, Gabe is 31 years old and Catherine is 25 years old.

She pays only $2300.

consumer surplus = $3000 - $2300 = $700

Answer:

$700

Anna's consumer surplus is the difference between her willingness to pay and the price she actually paid, which is $3000 - $2300 = $700.

Therefore, the answer is $700.

The solution of the given differential equation is,  ln|y+√x²+4| =  (3√2 + 2).eᵡ.

The given differential equation is,

dy/dx = √x²+4

It can be solved by using the separation of variables as,

dy/√x²+4 = dx

Integrating both sides:

∫dy/√x²+4 = ∫dx

Let's use a substitution,

let x = 2tanθ ,

dx/dθ = 2sec²θ and

√x²+4 = 2secθdy/2secθ

= 2sec²θdθdy

= 2secθ*2sec²θdθdy

= 2(2sec³θ)dθdy

= 4sec³θdθ

Now,

∫dy/√x²+4 = ∫dx∫4sec³θdθ

= ∫dx

To integrate sec³θ , we will use integration by parts as,

∫sec³θdθ = ∫secθ . sec²θdθ∫sec³θdθ

= secθ . tanθ - ∫tanθ . secθ . tanθdθ∫sec³θdθ

= secθ . tanθ - ∫(sec²θ-1)secθdθ∫sec³θdθ

= secθ . tanθ - ∫sec³θdθ + ∫secθdθ∫sec³θdθ

= secθ . tanθ + ln|secθ+tanθ|

Applying the limits,

∫dy/√x²+4 = ∫dx∫4sec³θdθ

= ∫dx   From x = 0,θ = 0 ,

From x = 2,θ = π/4

∫dy/√x²+4 = ∫dx∫0π/4 4sec³θdθ

= ∫02dx∫dy/√x²+4

= x + C∫dy/√x²+4

= x + Cln|y+√x²+4|

= x + C

As per the given differential equation, y(0) = 3√2

On substituting x = 0,

y = 3√2ln|3√2+√0²+4|

= 0 + Cln|3√2+2|

= C

So, the solution of the differential equation is given by:

ln|y+√x²+4| = x + ln|3√2+2|ln|y+√x²+4|

= ln(3√2+2) + x

By taking exponentials on both sides we get,

y + √x²+4 = C.eᵡ

Now, let's put x = 0 and y = 3√2 in the above equation to find the constant C:

y + √x²+4 = C.eᵡ3√2 + √0²+4

= C.e⁰3√2 + 2

= C
