The value of p is -1 in the given equation of of parabola.

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical planar curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point called focus and a line called the directrix.

Equation for a Parabola

The general formula or the equation for representing a parabola is given by,

y² = 4px

Here,  (h,k) being the vertex of the parabola,

y = a(x-h)² + k

x = b(y-k)² + h

The focus of this parabola is given by (p, 0).

The directrix of the parabola is the line drawn perpendicular to the y-axis and traversing the point (-p, 0). The directrix is parallel to the parabola's axis.

What is the value of p in the equation for parabola?

The given equation is,

y² = -4x

Comparing this equation with the general formula of the parabola, we get,

p = -1

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

where:

Given:

Substitute the given values into the circle equation and solve for r:

[tex]\implies r^2=(-3-5)^2+(2-(-4))^2[/tex]

[tex]\implies r^2=(-8)^2+(6)^2[/tex]

[tex]\implies r^2=64+36[/tex]

[tex]\implies r^2=100[/tex]

[tex]\implies r=\sqrt{100}[/tex]

[tex]\implies r=10[/tex]

Substitute the given center and the found value of r into the circle equation to create the equation of the circle:

Answer:

$80,000

Step-by-step explanation:

Define the variables:

Let x =  "fish-flavored" chicken company investment (in dollars)

Let y = spray-on vitamins company investment (in dollars)

If Allen invested a total of $100,000:

⇒ x + y = 100000

Given:

⇒ 0.03x + 0.01y = 2600

Rewrite the first equation to make y the subject:

⇒ y = 100000 - x

Substitute into the second equation and solve for x:

⇒ 0.03x + 0.01(100000 - x) = 2600

⇒ 0.03x + 1000 - 0.01x = 2600

⇒ 0.02x + 1000 = 2600

⇒ 0.02x = 1600

⇒ x = 80000

Therefore, Allen invested $80,000 in the "fish-flavored" chicken company.

Step-by-step explanation:

New information obtained through research or experimentation that enables an updating or revision of the state-of-nature probabilities is known as SAMPLE INFORMATION.

Hence, 2nd option is the best choice.

A statistical concept called joint probability determines the chance that two events will occur simultaneously and at the same time.

A sample is a collection of people, things, or things used in the study that is taken for analysis from a wider population. To enable us to extrapolate the study sample's findings to the entire population, the sample must be representative of the population. Sample information is the collection of the information of the sample.

The possibility of an event or outcome happening contingent on the occurrence of a prior event or outcome is known as conditional probability. The probability of the prior event is multiplied by the current likelihood of the subsequent, or conditional, occurrence to determine the conditional probability.

The expected utility of a course of action is a weighted average of the utilities of each of its potential outcomes, where the utility of a potential result indicates how much it is preferred to the alternatives.

In the question, we are asked what will be the new information obtained through research or experimentation that enables an updating or revision of the state-of-nature probabilities called.

As we are to name the information, it will be called sample information, from the above-discussed points.

Answer:

Yes, Maureen is correct. If a system of linear equations has three equations, then there could be exactly two solutions to the system. This is because, in general, a system of linear equations with three variables will have three equations. However, if two of the equations are the same, then there will only be two equations. In this case, there will be two solutions to the system.

The angle between the lines joining the origin to the points of intersection of the degenerated elipse and the straight line is approximately 136.635°.

We have the graphs of a degenerated ellipse and a line, which intercept each other at points (x₁, y₁) = (-0.293, 1.121) and (x₂, y₂) = (- 1.707, - 3.121). A representation of the situation is shown in the image attached below.

Answer:

PART A:

The range, the IQR (inter-quartile range) and the standard deviations are measures which are used to measure the spread of a data set.

A dataset is more consistent relative to another data set when the standard deviation is less than that of the other data set.

From the table, it can be seen that Team C has the least standard deviation.

Therefore, If the club wants to award the team that has the most consistent scoring among its team members, team C should be chosen.

PART B

The mean and the median is a measure of center of a data set.

The mean describes the average of a data set.

From the table, it can be seen that Team B has the highest average score.

Therefore, If the club wants to award the team with the highest average score, team B should be chosen.

When the multiplicity of a real root is even, the graph of the function neither crosses nor is tangent to the x-axis. The correct answer is (c) the graph is tangent to the y-axis.

When a real root has an even multiplicity, it means that the corresponding factor appears multiple times in the factored form of the polynomial. In terms of the graph of the function, this means that the graph touches the x-axis at that root but does not cross it.

Since the graph touches the x-axis without crossing it, it remains on one side of the axis. This behavior indicates that the graph is tangent to the x-axis at the root with even multiplicity.

However, the graph can still intersect or cross the y-axis at a different point depending on other factors or terms in the polynomial. Therefore, option (a) "the graph crosses the y-axis" may or may not be true depending on the overall behavior of the function. The statement in option (b) "the graph crosses the x-axis" is incorrect for an even multiplicity root. Option (d) "the graph is tangent to the x-axis" is also incorrect for an even multiplicity root. Hence, option (c) "the graph is tangent to the y-axis" is the correct choice.

T probability of rolling doubles after 45 tosses is 0.156

To do this, we enter the data values in a graphing calculator.

From graphing calculator, we have the following summary:

The regression equation is

y = bx + a

Where

b = SP/SSX = 1375/8250 = 0.16667

a = MY - bMX = 8.7 - (0.17*55) = -0.46667

So, we have:

y = 0.16667x - 0.46667

Approximate

y = 0.167x - 0.467

When the number of tosses is 45, we have:

y = 0.167 * 45 - 0.467

Evaluate

y = 7.048

Approximate

y = 7

45 tosses gives 7 doubles.

So, the probability is:

P = 7/45

Evaluate

P = 0.156

Hence, the probability of rolling doubles after 45 tosses is 0.156

A function composed with its inverse outputs the original input.

It is proved in the answer that an exterior angle of the triangle equals the sum of two opposite interior angles.

If a triangle's side is created, the outside angle that results is equal to the product of the two opposite internal angles.

In the figure given below we can see:

∠BCD is the exterior angle of the triangle

∠ABC + ∠BAC + ∠BCA = 180° (Angle sum property of a triangle)

∠BCA + ∠BCD = 180°(Linear pair)

From both equations we can say that:

∠ABC + ∠BAC + ∠BCA  = ∠BCA + ∠BCD

∠ABC + ∠BAC = ∠BCD

Since 2704 = 2⁴ × 13², we need [tex]m = 13[/tex] and [tex]n=2[/tex], since this gives

[tex]\dfrac{2704m}n = \dfrac{2^4 \times 13^2 \times 13}2 = 2^3 \times 13^3 = 26^3[/tex]

The values of m and n that make 2704 × m/n a perfect cube are:

m = 13 and n = 2.

We have,

We can start by factoring 2704, which is 52².

So we have:

= 2704 × m/n

= 52² × m/n

= (2² × 13²) × m/n

For the expression to be a perfect cube, we need all the prime factors to appear in groups of three.

Since 2 and 13 appear only once each, we need to find another factor that appears twice.

Since m and n are both prime, and the fraction m/n is simplified, there are only two possible values for m and n:

m = 2 and n = 13, or

m = 13 and n = 2

Let's try the first case:

2704 × m/n = 2704 × 2/13 = 416

416 is not a perfect cube, so this case does not work.

Now let's try the second case:

2704 × m/n = 2704 × 13/2 = 17696

17696 is 28³, which is a perfect cube.

Therefore,

The values of m and n that make 2704 × m/n a perfect cube are:

m = 13 and n = 2.
