Answer:

B

Step-by-step explanation:

True.

Given the statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

For the given question,

The distance from 0 to x on a number line is greater than 5

We write the above statement in mathematical expression form as,

⇒ |x - 0| > 5

⇒ |x| > 5

⇒ x > 5  

We need to determine the value of an expression -5 + x

From (1),

⇒ x > 5  

Subtract -5 from both sides,

⇒ -5 + x = -5 + 5

⇒ -5 + x > 0

From the above expression, we observe that the value of the expression is always greater than 1.

This means the value of an expression -5 + x is positive.

Therefore, the given statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.

In mathematics, a number line can be described as a figure that symbolizes numbers on a consecutive line. The digits on a number line are positioned successively with equal spacing along its length. It can be infinitely expanded in any direction and is often depicted horizontally.

Absolute value is the distance between a digit and zero on a number line. Since the space is forever positive, the absolute value will always be positive.

To write the equation for a circle with a diameter whose endpoints are (1, 14) and (7, -12) in standard form, we'll need to follow the following steps:Step 1: Find the center of the circle by finding the midpoint of the diameter.

= [(x1 + x2)/2, (y1 + y2)/2]Midpoint

= [(1 + 7)/2, (14 + (-12))/2]Midpoint

= (4, 1)So, the center of the circle is (4, 1).Step 2: Find the radius of the circle. The radius of the circle is half the length of the diameter, which is the distance between the two endpoints. The distance formula can be used to find this distance. Diameter

= √((x2 - x1)² + (y2 - y1)²)Diameter

= √((7 - 1)² + (-12 - 14)²)Diameter

= √(6² + (-26)²)Diameter

= √(676)Diameter

= 26So, the radius of the circle is half the diameter or 26/2 = 13.Step 3: Write the equation of the circle in standard form, which is (x - h)² + (y - k)²

= r². Replacing the center (h, k) and radius r, we get:(x - 4)² + (y - 1)² = 13²Simplifying this equation, we get:x² - 8x + 16 + y² - 2y + 1 = 169x² + y² - 8x - 2y - 152

(a) the probability expected number of flips needed to get three heads in a row is 7.5.

(b) The expected number of flips needed to get k heads in a row is 2k - 1.

A fair coin is one where the probability of obtaining heads is equal to the probability of obtaining tails, that is, P(H) = P(T) = 1/2. When a fair coin is flipped repeatedly, the expected number of flips needed to get three heads in a row is 7.5. This is because the probability of getting three heads in a row is (1/2)^3 = 1/8. This means that on average, 8 flips need to be made for three heads to appear, so the expected number of flips is 7.5.Similarly, the expected number of flips needed to get k heads in a row is 2k - 1. This is because the probability of getting k heads in a row is (1/2)^k. This means that on average, 2k flips must be made for k heads to appear, so the expected number of flips is 2k - 1. For example, the expected number of flips needed to get five heads in a row is 9, since the probability of getting five heads in a row is (1/2)^5 = 1/32, and 32 flips need to be made on average before five heads appear, so the expected number of flips is 9

Answer:

Given: Two Isosceles triangle ABC and Δ PBC having same base BC. AD is the median of Δ ABC and PD is the median of Δ PBC.

To prove: Point A,D,P are collinear.

Proof:

→Case 1.  When vertices A and P are opposite side of Base BC.

In Δ ABD and Δ ACD

AB= AC   [Given]

AD is common.

BD=DC  [median of a triangle divides the side in two equal parts]

Δ ABD ≅Δ ACD [SSS]

∠1=∠2 [CPCT].........................(1)

Similarly, Δ PBD ≅ Δ PCD [By SSS]

∠ 3 = ∠4 [CPCT].................(2)

But,  ∠1+∠2+ ∠ 3 + ∠4 =360° [At a point angle formed is 360°]

2 ∠2 + 2∠ 4=360° [using (1) and (2)]

∠2 + ∠ 4=180°

But ,∠2 and ∠ 4 forms a linear pair i.e Point D is common point of intersection of median AD and PD of ΔABC and ΔPBC respectively.

So, point A, D, P lies on a line.

CASE 2.

When ΔABC and ΔPBC lie on same side of Base BC.

In ΔPBD and ΔPCD

PB=PC[given]

PD is common.

BD =DC [Median of a triangle divides the side in two equal parts]

ΔPBD ≅ ΔPCD  [SSS]

∠PDB=∠PDC [CPCT]

Similarly, By proving ΔADB≅ΔADC we will get,  ∠ADB=∠ADC[CPCT]

As PD and AD are medians to same base BC of ΔPBC and ΔABC.

∴ P,A,D lie on a line i.e they are collinear.

The bird should fly to a point on the shoreline that is 4km from B to minimize total energy expenditure. A large W/L ratio means it's more efficient to fly over land, while a small ratio means it's more efficient to fly over water. The minimum ratio is 2.834. The W/L ratio should be 1 for the bird to fly directly to D, and 0 for the bird to fly to B and then along the shore to D. It takes a bird 1.4 times more energy to fly over water than land.

To minimize the total energy expended in returning to its nesting area, the bird should fly to the point on the shoreline that is 4 km from B. This can be found using the principle of least action, which states that the bird will choose the path that minimizes the integral of the energy expended along the path.

A large value of the ratio W/L would mean that it takes significantly more energy to fly over water than over land. A small value of the ratio would mean that there is not much difference in energy expenditure between flying over water and over land. The ratio W/L corresponding to the minimum expenditure of energy can be found using the same principle of least action as in part (a).

we are asked to determine the ratio W/L corresponding to the minimum expenditure of energy. Let x be the distance from B to C, and let y be the distance from C to D along the shoreline. Then the total energy expended in returning to its nesting area is given by

E(x, y) = L(13 - x - y) + W(√(25 - x²)) + W(√(y² + (13 - x)²))

To minimize E(x, y), we take partial derivatives with respect to x and y and set them equal to zero

dE/dx = L + Wx/√(25 - x²) - Wy/√(y² + (13 - x)²) = 0

dE/dy = L - Wy/√(y² + (13 - x)²) = 0

Solving for x and y, we get

x = 5√((W/L)/(1.4(W/L) - 1))

y = 13 - x - 5√((W/L)/(1.4(W/L) - 1))

The ratio W/L corresponding to the minimum expenditure of energy is obtained by substituting these values into the expression for E(x, y) and simplifying

W/L = 2.5(1.4 + √(1.96 + 4/25))/(4.9 - √(1.96 + 4/25))

W/L ≈ 2.834

Therefore, the ratio W/L corresponding to the minimum expenditure of energy is approximately 2.834.

To fly directly to its nesting area D, the value of W/L should be equal to 1. To fly to B and then along the shore to D, the value of W/L should be equal to 0.

If birds of a certain species reach the shore at a point 4 km from B, it takes 1.4 times more energy for the bird to fly over water than over land. This can be found by comparing the energy required to fly directly from the island to the point on the shoreline that is 4 km from B (which is entirely over water) to the energy required to fly along the shoreline from that point to D (which is entirely over land).

The scatter plot of the data shows a linear relationship between the number of weeks (x) and the amount of money saved (y).

In the scatter plot, the x-axis represents the number of weeks, and the y-axis represents the amount of money saved. The initial amount of money saved is $10, and each week $5 is added to the savings.

To create the scatter plot, we start with the initial point (0, 10) on the graph, which represents the starting point. Then, for each subsequent week, we add $5 to the y-coordinate and increment the x-coordinate by 1. This process is repeated for the desired number of weeks.

The resulting scatter plot will show a series of points that form a straight line with a positive slope. Each point on the line represents the number of weeks and the corresponding amount of money saved at that time. As the number of weeks increases, the amount of money saved increases linearly.

Overall, the scatter plot visually represents the relationship between the number of weeks and the amount of money saved, showing the incremental growth of savings over time.

Answer:

y = 1sin(3x)

Step-by-step explanation:

y = A sin( (2π/ω)x )

A is amplitude = 1

ω is period = 2π/3

------------------------------

y = 1sin( 2π / (2π/3) x)

y = 1sin(3x)

The equation for the graph with a sinusoidal wave, given an amplitude of 1, a period of 2π/3, and a phase shift of 0, is y = sin((2π/3)x).

The equation for a sinusoidal wave can be written as:

y = A * sin(ωx + φ)

In this case, we are given the values of amplitude (A = 1), period (ω = 2π/3), and phase shift (φ = 0).

The amplitude (A) represents the maximum displacement or height of the wave from the center line. In this case, it is 1.

The period (ω) represents the length of one complete cycle of the wave. The period is the reciprocal of the frequency, and in this case, it is 2π/3.

The phase shift (φ) represents any horizontal displacement of the wave. In this case, the phase shift is 0, indicating that the wave starts at its equilibrium position.

Using these values, the equation for the given graph would be:

y = 1 * sin((2π/3)x + 0)

Simplifying it further:

y = sin((2π/3)x)

We can conceptually isolate the strength of the evidence from the prior probability of the theory when we make observations first or form our hypotheses first. Correct option is C.

The concept of isolating the strength of evidence from the prior probability of the theory is known as Bayesian inference, which involves updating our prior beliefs about a theory or hypothesis based on the observed evidence.

This process can be done whenever we have some initial prior belief about the theory or hypothesis and then collect new evidence to test it.

In Bayesian inference, the strength of evidence is measured by the likelihood of the observed data given the theory or hypothesis, and the prior probability is the initial belief or probability assigned to the theory or hypothesis before the evidence is considered.

By combining these two sources of information, we can calculate a posterior probability or updated probability of the theory or hypothesis given the observed evidence.

Therefore, the answer is c) whether we make observations first or form our hypotheses first. The order in which we collect the evidence or form hypotheses does not affect our ability to conceptually isolate the strength of the evidence from the prior probability of the theory, as long as we use Bayesian inference to update our beliefs.

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a conversion factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.

(a) The given units can be converted as follows: 6 glints = 1 filn...

(1)12 grees = 1 zool...

(2)2 grees = 10 twibbs...

(3)5 grees = 1 bic...

(4)Note that the grees are in both the numerator and denominator of the second unit conversion factor (3). Hence we can cancel out the grees by using it twice in the numerator and denominator. Now using the given conversion factors in equation (1), we get:

7 glint/twibb=7 glint/ (10 grees/2 grees)=14 glint/10 grees=14 glint/ (5 grees/12 grees)=16.8 filn/strord

(b) We need to convert the result of part (a) from filn/strord to megafiln/strord.

1 mega = 106

Thus 1 megafiln = 106 filn

16.8 filn/strord = (16.8 filn/strord) x (1 megafiln/106 filn) = 1.68 x 10-5 megafiln/strord

The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.
