Answer:

14

Step-by-step explanation:

When we round 61.604 to the nearest whole number, we get 62, and when we round 48.44 to the nearest whole number, we get 48.

Therefore, we can estimate 61.604 - 48.44 by subtracting 48 from 62:

62 - 48 = 14

So, the estimated answer is 14.

the regular heptagon has only one line of reflectional symmetry, and it passes through the center of the heptagon. This property is common to all regular polygons, and it is related to their rotational symmetry.

The statements that are true about the reflectional  symmetryof a regular heptagon are:

It has only one line of reflectional symmetry.

The line of reflectional symmetry passes through the center of the heptagon.

A regular heptagon is a polygon with seven equal sides and angles. Each vertex of the heptagon is equidistant from the center of the heptagon, and the lines connecting the center to the vertices divide the heptagon into seven congruent triangles.

To understand the reflectional symmetry of the regular heptagon, we need to define what it means. Reflectional symmetry is a type of symmetry where a figure is symmetric with respect to a line. In other words, if we fold the figure along this line, one half will coincide with the other half.

In the case of the regular heptagon, we can observe that if we draw a line passing through the center of the heptagon and perpendicular to any of its sides, we obtain a line of reflectional symmetry. This line divides the heptagon into two congruent halves. However, if we draw any other line of reflectional symmetry, it will not coincide with the sides of the heptagon, and therefore, it will not divide the heptagon into congruent halves.

Therefore, we conclude that the regular heptagon has only one line of reflectional symmetry, and it passes through the center of the heptagon. This property is common to all regular polygons, and it is related to their rotational symmetry.

Therefore , the solution of the given problem of standard deviation comes out to be option C with n = 1,000 and p near to 1/2 is the right response.

Statistics uses variance as a way to quantify difference. The image of the result is used to compute the average deviation between the collected data and the mean. Contrary to many other valid measures of variability, it includes those pieces of data on their own by comparing each number to the mean. Variations may be caused by willful mistakes, irrational expectations, or shifting economic or business conditions.

Here,

The following algorithm determines the standard deviation of the sampling distribution of a sample proportion p:

=> √((p*(1-p))/n)

where n is the sample size, and p is the population percentage.

For the sampling distribution of a sample proportion p,

the pair of sample number n and population proportion p that would result in the highest standard deviation is:

=>n =1,000, and p is almost half.

Because p=1/2

yields the highest possible value of the expression (p*(1-p)), a bigger sample size will result in a smaller standard deviation.

The standard deviations will be lower for the other choices, which have smaller sample sizes or extreme values of p.

Therefore, (C) with n = 1,000 and p near to 1/2 is the right response.

The distance BC from Tower 2 to the plane is equal to 18,674 feet.

The height of the plane from the ground is equal to 7,595 feet.

In order to determine the distance from Tower 2 to the plane (BC), we would apply the law of sine (sine law) because we have two angles and one side length.

In Mathematics and Geometry, the law of sine is modeled or represented by this mathematical equation:

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

Answer:

a)  The length of BC is 15,052 ft to the nearest foot.

b)  The length of CD is 6,122 ft to the nearest foot.

Step-by-step explanation:

Angles on a straight line sum to 180°. Therefore:

[tex]\implies m \angle ABC +24^{\circ}=180^{\circ}[/tex]

[tex]\implies m \angle ABC =156^{\circ}[/tex]

Interior angles of a triangle sum to 180°. Therefore:

[tex]\implies m \angle BCA+16^{\circ}+156^{\circ}=180^{\circ}[/tex]

[tex]\implies m \angle BCA=8^{\circ}[/tex]

[tex]\boxed{\begin{minipage}{7.6 cm}\underline{Sine Rule} \\\\$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$\\\\\\where:\\ \phantom{ww}$\bullet$ $A, B$ and $C$ are the angles. \\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides opposite the angles.\\\end{minipage}}[/tex]

Use the Sine Rule to find the length of BC.

[tex]\implies \dfrac{AB}{\sin BCA}=\dfrac{BC}{\sin CAB}=\dfrac{AC}{\sin ABC}[/tex]

[tex]\implies \dfrac{7600}{\sin 8^{\circ}}=\dfrac{BC}{\sin 16^{\circ}}[/tex]

[tex]\implies BC=\dfrac{7600\sin 16^{\circ}}{\sin 8^{\circ}}[/tex]

[tex]\implies BC=15052.0746...[/tex]

[tex]\implies BC=15052\; \sf ft\;(nearest\;foot)[/tex]

Therefore, the length of BC is 15,052 ft to the nearest foot.

Interior angles of a triangle sum to 180°. Therefore:

[tex]\implies m \angle BCD+24^{\circ}+90^{\circ}=180^{\circ}[/tex]

[tex]\implies m \angle BCD=66^{\circ}[/tex]

[tex]\boxed{\begin{minipage}{9 cm}\underline{Sine trigonometric ratio} \\\\$\sf \sin(\theta)=\dfrac{O}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

To find the length of CD, use the sine trigonometric ratio.

[tex]\implies \sin 24^{\circ}=\dfrac{CD}{BC}[/tex]

[tex]\implies CD=BC\sin 24^{\circ}[/tex]

Substitute the found value of BC into the equation:

[tex]\implies CD=\left(\dfrac{7600\sin 16^{\circ}}{\sin 8^{\circ}}\right)\sin 24^{\circ}[/tex]

[tex]\implies CD=6122.23031...[/tex]

[tex]\implies CD=6122\; \sf ft\;(nearest\;foot)[/tex]

Therefore, the length of CD is 6,122 ft to the nearest foot.

The equation that represents the value of the collection after 5 years is:

Value of collection after 5 years = 190 x (1 + 0.06)^5

Explanation:

To calculate the value of the collection after 5 years, we need to use the compound interest formula. This formula is represented as A = P x (1 + r)^n, where P is the principal amount (initial value of the collection), r is the rate of interest (in this case, 6%), and n is the number of years (in this case, 5).

Therefore, the equation for the value of the collection after 5 years is:

Value of collection after 5 years = 190 x (1 + 0.06)^5

This can also be written as:

Value of collection after 5 years = 190 x 1.31 (1.31 is the result of (1 + 0.06)^5)

Therefore, the value of the collection after 5 years is $246.90.

Mainly, it represents the possibility of staring at a test statistic as a minimum as extreme as the one computed, assuming that the null hypothesis is genuine.

If the p-value is small, commonly less than a chosen significance stage (e.g., 0.05), it shows that the determined data is unlikely to have took place by danger alone and provides proof against the null hypothesis. alternatively, a large p-value suggests that the determined information is consistent with the null speculation, and the evidence isn't sturdy enough to reject it.

Mason would save $7,618.32 in interest by paying off $8,500 immediately.

In other terms, compound interest is interest on principle + interest and refers to the addition of interest to the principal amount of a loan or deposit. Reinvesting interest, or adding it to the lent capital rather than paying it out or requesting payment from the borrower, results in interest being generated on the principle amount plus previously accrued interest in the next month. In economics and finance, compound interest is common.

Comparing compound interest to simple interest, which has no effect on previously accrued interest

Given that, Mason has a credit card debt of $15,600.

Using his original payment plan of 60 months we have:

[tex]I = P * (1 + r/n)^{(n*t)} - P[/tex]

Substitute the values we have:

[tex]I = 15,600 * (1 + 0.18/12)^(12*5) - 15,600\\I = 9,316.84[/tex]

For the new plan:

New balance = $15,600 - $8,500 = $7,100

[tex]I = 7,100 * (1 + 0.18/12)^(12*2) - 7,100\\I = $1,698.52[/tex]

Hence, over the course of 24 months, Mason would pay approximately $1,698.52 in interest.

The difference in interest paid between the two scenarios is:

$9,316.84 - $1,698.52 = $7,618.32

Therefore, Mason would save approximately $7,618.32 in interest by paying off $8,500 immediately.

The rate at which the distance between the car and the truck is changing when the car is 9 m from the intersection and the truck is 40 m from the intersection is about 19.187 m/s

The rate of change of a function is an indication of how fast the function's output changes per unit change in the input of the function.

Let y represent the distance of the car from the intersection, and let x represent the distance of the truck from the intersection, we get;

The distance between the car and the truck, d, can be obtained from Pythagorean Theorem as follows;

d² = y² + x²

2·d·d/dt = 2·y·dy/dt + 2·x·dx/dt

dy/dt = The speed of the car = 48 km/h = 40/3 m/s

dx/dt = The speed of the truck = 60 km/h = 50/3 m/s

y = The distance of the car from the intersection = 9 m

x = The distance of the truck from the intersection = 40 m

d² = 9² + 40² = 1681

d = √(1681) = 41

d = 41 m

Therefore;

2×41×d/dt = 2×9 × 40/3 + 2 × 40 × 50/3 = 4720/3
