prove that 32^5-16^5+2^19 is divisible by 63

Answer:

He would be 15 years old.

Step-by-step explanation:

If the difference is 15, and sarah is double the age, whatever age the youngest brother is, that number if multiplied by 2 or added to 15 needs to be the same answer. You could make a equation by writing those two on either side of the equation and making the unknown sum “x”. This would look like “2x=x+15”. Then to get the final product you would subtract the x on the right side from both side, ending up to be “x=15” in this scenario, that would be the final answer.

It falls between: The population mean is 13. 8. The population variance is 192. The population's standard deviation is 13.856.

A key measure of dispersion in statistics is population standard deviation. additional reading Statisticians compute variance to determine how various values inside a data collection interact to one another. While calculating the population variance, one may also compute the dispersion in relation to the population means.

The range: 15 - 2 = 13

The population mean is:

Mean = ( 2 + 10 + 15 + 2 + 12 + 13 + 7 + 3 + 8  ) / 9 = 8

The population variance ( S² or Sigma² ):

S ² = 1/9 · ( ( 2 - 8 )² + ( 10- 8 )² + ( 15 - 8 )² + ( 2 - 8 )² + ( 12 - 8 )² + ( 13 - 8 )² + ( 7 - 8 )² + ( 3 - 8 )² + ( 8 - 8 )²  )

S ² = 192

Zeroes & Multiplicity:

x = 0        :   Multiplicity = 2

x = -6/5   :   Multiplicity = 9

x = 8        :   Multiplicity = 2

Step-by-step explanation:

The equation provided is: [tex]f(x)=x^2(5x+6)^9(x-8)^2[/tex]

We're given the polynomial in factored form, which just means the polynomial is broken down into each of its factors. This is a really convenient form to have a polynomial in as we can easily find the zeroes of the polynomial.

This is due to the Zero Property of Multiplication, which essentially states zero times any number results in zero. So we just have to set each factor equal to zero, and solve, since if one of the factors is zero, then the entire thing becomes zero.

So this gives us the following equations:

[tex]x^2=0\implies x = 0\\\\(5x+6)^9=0\implies x = -\frac{6}{5}\\\\(x-8)^2=0\implies x = 8[/tex]

Now for the multiplicity, we just look at the exponent of the factor we set equal to zero. So x^2 gives us a zero of x = 0, and the exponent is 2, which is also the multiplicity of this zero.

The (5x + 6)^9 gives us a zero of x = -6/5, and the exponent is 9, which is also the multiplicity of the zero. Same thing applies for the zero at x = 8, which has a multiplicity of 2.

What is confidence interval?

A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

The common ratio is approximately -0.6.

Let the first term in the geometric series be "a" and the common ratio be "r". Then, the formula for the sum to infinity of a geometric series is:

S = a / (1 - r)

And the formula for the sum of the first n terms of a geometric series is:

Sn = a * (1 - r^n) / (1 - r)

So, using the information given:

18 = a / (1 - r)

And:

130/9 = a * (1 - r^4) / (1 - r)

Solving for "r" using these two equations:

18 = a / (1 - r) ==> a = 18 * (1 - r)

130/9 = a * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r) * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r^4)

Dividing both sides by 18:

7/5 = (1 - r^4)

So:

r^4 = 1 - 7/5 = -2/5

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, the length of a rectangle is 4 inches more than its width.

let x be the width of a rectangle.

thus, length = 4 + width

From the general formula of area and perimeter:

Area of rectangle = length*width

Perimeter of rectangle = 2(length + width)

In our case,

Area = x * (4 + x)

Area = x² + 4x

Perimeter = 2( 4 +x+ x)

Perimeter = 8 + 4x

Since the area of the rectangle is equal 5 inches more than 2 times the perimeter.

Thus,

x² + 4x = 5 + 2(8 + 4x)

x² + 4x = 5 + 16 + 8x

x² + 4x = 21 + 8x

x² + 4x -8x -21 = 0

If the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled a distance is 9.5 cm.

What is the circumference of the circle?

The Circumference of a circle is basically the perimeter of the circle. It is given as (2×π×r) or (π×d).

The hand on a circular clock moves along the circumference of the circle, and the length of the circumference of a circle is given by the formula:

C = 2 * π * r

where C is the circumference, π is Pi (approximately equal to 3.14), and r is the radius of the circle.

In this case, the radius of the circle is half the length of the hand, or 12cm / 2 = 6cm.

So the circumference of the circle is:

C = 2 * π * 6 = 12 * π

Since the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled an angle of 5 * (360/12) = 150 degrees.

To find the distance traveled along the circumference, we need to multiply the circumference by the fraction of the circle traveled, which is equal to the angle in radians divided by 2π.

To convert from degrees to radians, we can use the formula:

radians = degrees * (π / 180)

So, the distance traveled by the hand is:

distance = C * (150 * (π / 180)) / (2 * π) = 12 * (150 * (π / 180)) / 2 = 9.5 cm (rounded to the nearest cm)

hence, if the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled a distance is 9.5 cm.

Answer:

2,810 feet

Step-by-step explanation:

Take a look at the diagram

There are two triangles formed with a common side AB

AB represents the vertical height of the plane = 5150 feet

AC represents the distance of car 1 from O

In ΔABC, m∠A = 90°, m∠ABC = 38°

Since the three angles of triangle must add up to 180°
90 + 38 +m∠C = 180

128 + m∠C = 180°

m∠C = 180 - 128 = 52°

In a right angle triangle where one side is the angle ∅, the ratio of the side opposite this angle to the side adjacent to the angle is tan∅

Using the values provided we get
tan(52°) = 5150/AC

AC= 5150/tan(52) = 4,023.62 feet ≈ 4024 feet

This is the horizontal distance of the first  car from the plane

Similarly for ΔABD

m∠D = 180 - (90 + 53) = 37°
tan(37) = 5150/AD

AD= 5150/tan(53) = 6,834.28 feet ≈ 6834 feet

This is the horizontal distance of the second car from the plane

The distance between the two cars = 6,834 - 4,024

= 2,810 feet

What is Strictly convex function?

A real-valued function is said to be convex if the line segment connecting any two points on its graph falls above the graph connecting the two points. A function is convex if and only if its epigraph is a convex set.

Since f"(x) > 0 for all x in (0,2), it follows that f is a strictly convex function on that interval, meaning that its second derivative is positive and its first derivative is increasing.

If f is a strictly convex function on [0,2], then f(2-x) is a strictly concave function on [0,2]. The sum of a strictly convex and a strictly concave function is also a strictly convex function.

Therefore, since f''(x) = f(x) + f(2-x), it follows that f''(x) is a strictly convex function on [0,2], which means that its first derivative is increasing.

Inequality Interval Notation Graph

Sajan Rai

Solve the inequalities below. Write the solution set in interval notation and graph the solution.

8x−12>158x-12>15

Solution:

Interval notation for the solution:

(-∞,5/8) U (5/8, ∞)

To graph the solution, we need to find the points that make the inequality true and shade the region that corresponds to these points. On the number line, we can start by finding x values that make the inequality equal to zero:

8x - 12 = 0

x = 12/8 = 3/2

and

15 - 8x = 0

x = 15/8 = 9/4

Next, we need to test values that are less than 3/2 and greater than 9/4 to determine the direction of the inequality. If the inequality is true for values less than 3/2, then we shade the region to the left of 3/2. If the inequality is true for values greater than 9/4, then we shade the region to the right of 9/4. In this case, since the inequality is "greater than," the shading goes to the right of 9/4 and to the left of 3/2.

The mean of the probability distribution is 3.188, the sampling distribution is 2.25 and x is an unbiased estimator.

a. To find the mean (u) of a probability distribution, we calculate the expected value as follows:

u = ∑x * p(x) = (0.5 * 0.0625) + (2.5 * 0.125) + (0.25 * 0.25) + (0.25 * 0.25) + (0.25 * 0.25) = 2.25

To find the variance (o^2) of the distribution, we calculate it as follows:

o^2 = ∑(x - u)^2 * p(x) = (0.5 - 2.25)^2 * 0.0625 + (2.5 - 2.25)^2 * 0.125 + (0.25 - 2.25)^2 * 0.25 + (0.25 - 2.25)^2 * 0.25 + (0.25 - 2.25)^2 * 0.25 = 0.5625

So, o = √0.5625 = 3.188

b. The sampling distribution of the sample mean x for a random sample of n=2 measurements from this distribution is given by:

x = (x1 + x2) / n = (2.25 + 2.25) / 2 = 2.25

As n approaches infinity, the sample mean x approaches the population mean u, and the distribution of x becomes more and more concentrated around u.

c. Yes, x is an unbiased estimator of u because its expected value is equal to the population mean: E(x) = u.
