True of False?

False, one can tell if a data set is close to symmetric or not by watching a histogram.

             The histogram exhibit a symmetrical distribution of given data. The data is symmetrical if we are able to draw a vertical line at some point in the histogram such that its shape on both sides of the left and the right of the vertical line exactly reflected images to each other. The mean, the median, and the mode are can be taken as examples to prove the symmetricity using histogram for these data.  

         In an altogether symmetrical distribution, the mean and the median are alike. Such as the mode has one mode (unimodal), and the mode is the alike as the mean and median.

Step-by-step explanation:

Im confused what you're trying to say.

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

Answer:

Rectangle 1: 84 ft^2   Rectangle 2: 8 ft^2

Step-by-step explanation:

Split the figure into two rectangles

Rectangle 1:

Width of rectangle 1 can be found by subtracting 8 ft from 15 ft

15-8=7 ft (width)

length is already given as 12 ft

So,

A = L x W

A = 12ft x 7 ft

A = 84 ft^2

Length is already given of one of the rectangles

Rectangle 2:

Finding the width of Rectangle 2 can be found by subtracting 11 ft from 12 ft to find the length of that dashed line or the width of rectangle 2.

12 ft - 11 ft = 1ft (width)

Length: 8 ft

Width: 1ft

A=l x w

A=8 x 1

A=8 ft^2

The balance after 6 years on an account that pays 5.5% annual interest compounded continuously with an initial deposit of $975 is $1,356.19.

Continuous compounding involves calculating the interest earned on a principal amount continuously over time, which results in a higher overall balance than other compounding frequencies.

Using the formula A = Pe^(rt), where A is the final balance, P is the initial deposit, r is the interest rate, and t is the time, we can calculate the balance after 6 years as A = 975e^(0.055*6) = $1,356.19. Therefore, the correct answer is option D, $1,356.19.

90 people.

Step-by-step explanation:

60% can be deduced to a fraction of 6/10. If 6/10=150, then you can cross multiply 6*150 and 10*1. 900/10=90.

 The greatest common factor is the biggest number that divides evenly into each one of the numbers without a remainder...the only thing that's different about our situation is that we have variables in addition to regular number (but the same logic applies...we need to find the biggest variable that goes into k^4 , k^3 , and k^2 ).

The biggest number that goes into 15, 35 and 20 is the number 5. The biggest variable that goes into k^4 , k^3 , and k^2 is k^2

Combining the number and the variable, we get that the greatest common monomial factor is 5k^2

Since area is length x width, and we just figured out that width is 5k2 , all we have to do to find length is divide 15k4+35k3+20k2 by 5k2 , and we get that the length is 3k^2+7k+4

So the width is 5k^2 and the length is 3k2+7k+4

It is a rectangular region with u and v values ranging from 1 to 2.

To find the Jacobian of the transformation x = 3u, y = 2uv, we need to compute the partial derivatives ∂x/∂u, ∂x/∂v, ∂y/∂u, and ∂y/∂v.

Given:

x = 3u

y = 2uv

Calculating the partial derivatives:

∂x/∂u = 3

∂x/∂v = 0 (since x does not depend on v)

∂y/∂u = 2v

∂y/∂v = 2u

Now, we can construct the Jacobian matrix J:

J = [∂x/∂u   ∂x/∂v]

   [∂y/∂u   ∂y/∂v]

Substituting the partial derivatives we calculated earlier:

J = [3   0]

   [2v  2u]

Therefore, the Jacobian of the transformation is:

J = [3   0]

   [2v  2u]

To sketch the region described by the inequalities g: 3 < 3u < 6, 2 < 2uv < 4, we can consider the ranges of u and v that satisfy these conditions.

From the inequality 3 < 3u < 6, we have:

1 < u < 2

From the inequality 2 < 2uv < 4, we can divide both sides by 2:

1 < uv < 2

Since u and v must both be greater than 1, we can determine the range of v:

1 < v < 2

Now, we can sketch the region in the u-v plane bounded by the conditions:

1 < u < 2

1 < v < 2

It is a rectangular region with u and v values ranging from 1 to 2.

Determine the slope of the line by selecting any two points from the tableSubstitute the slope, and the coordinates of one of the points into the slope-intercept formulaSimplify the equation to its slope-intercept form

The slope-intercept formula is y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept of the line.

The y-intercept is the point at which the line crosses the y-axis.The table below shows the x and y values for a given data: x y 1 3 2 4 3 5 4 6To determine the slope of the line,

we can select any two points from the table and apply the formula for slope, which is: Slope = change in y/change in x or (y2 - y1)/(x2 - x1)Let's choose points (1,3) and (2,4):

Slope = (4 - 3)/(2 - 1) = 1/1 = 1Now, we substitute the slope value and one of the points into the slope-intercept formula and solve for b.

We can choose any of the points, but let's use (1,3):y = mx + by = 1x + b3 = 1(1) + bb = 3 - 1 = 2The value of b is 2. Now that we have both m and b, we can write the equation in slope-intercept form:y = mx + by = 1x + 2y = x + 2

(A) Circular orbits of stable particles are possible at radii greater than three times the Schwarzschild radius for the non-rotating spherically symmetric mass.

This represents the radius of a black hole's event horizon, within which nothing can escape. The Schwarzschild radius is the event horizon radius of a black hole with mass M.

M can be calculated using the formula: r+ = 2Mwhere r+ is the radius of the event horizon.

(B)  1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ R. This is the required expression.

Tau is the proper time of the particle moving around a circular orbit. Hence, by making use of the formula given above:1/2 M -1/2 3M (²) ¹² (1-³) dT = R³ dt.

(C) Time passes differently in different gravitational fields, and it follows that the period as measured at infinity should be larger than that measured by the particle.

The principle of equivalence can be defined as the connection between gravitational forces and the forces we observe in non-inertial frames of reference. It's basically the idea that an accelerating reference frame feels identical to a gravitational force.

(D) The period of the orbit as measured by an observer at infinity is 16π M^(1/2) and the period of the orbit as measured by the particle is 16π M^(1/2)(1 + 9/64 M²).

The period of orbit as measured by an observer at infinity can be calculated using the formula: T = 2π R³/2/√(M). Substitute the given values in the above formula: T = 2π (8M)³/2/√(M)= 16π M^(1/2).The period of the orbit as measured by the particle can be calculated using the formula: T = 2π R/√(1-3M/R).

Substitute the given values in the above formula: T = 2π (8M)/√(1-3M/(8M))= 16π M^(1/2)(1 + 9/64 M²).

Step by Step Explanation:

False. The equation 10x ≡ -6 mod 32 does not have two distinct solutions mod 32.

In modular arithmetic, the equation ax ≡ b mod n can have multiple solutions when a and n are not coprime (i.e., they have a common factor other than 1). However, in this case, we can see that 10 and 32 share a common factor of 2. Therefore, we can divide both sides of the equation by 2 to simplify it:

5x ≡ -3 mod 16

Now, let's consider the possible values of x mod 16. The residues for -3 multiplied by 5 (modulo 16) are as follows:

-3 * 5 = -15 ≡ 1 mod 16

-3 * 10 = -30 ≡ 2 mod 16

-3 * 15 = -45 ≡ -13 mod 16

-3 * 20 = -60 ≡ 4 mod 16

...

We can observe that as we continue multiplying -3 by multiples of 5, the residues repeat after every 8 terms. Therefore, the equation has a periodic pattern with a period of 8, and we can conclude that there are at most 8 distinct solutions mod 16. Since 32 is a multiple of 16, the equation cannot have more than 8 distinct solutions mod 32.
