Step-by-step explanation:

When x is -3, your answer is 2.

When x is -1, your answer is 10.

When x is 0, your answer is undefined.

the difference between the theoretical standard deviation and the sample standard deviation is  0.71.

calculate the theoretical standard deviation using the formula for a uniform distribution:

Theoretical Standard Deviation = (b - a) / √12

Where "a" and "b" are the lower and upper bounds of the distribution, which in this case are 13 and 45 respectively.

Theoretical Standard Deviation = (45 - 13) / √12 ≈ 4.608

Next,  calculate the sample standard deviation using the given data:

Step 1: Calculate the sample mean (x)

x = (15 + 18 + 15 + 21 + 20 + 23 + 14 + 18 + 23 + 25) / 10 = 19.2

Step 2: Calculate the sample variance s² :

s² = [(15 - 19.2)² + (18 - 19.2)² + (15 - 19.2)² + (21 - 19.2)² + (20 - 19.2)² + (23 - 19.2)² + (14 - 19.2)² + (18 - 19.2)² + (23 - 19.2)² + (25 - 19.2)²] / 9

   ≈ 15.2

Step 3: Calculate the sample standard deviation (s)

s = √15.2 ≈ 3.898

Finally, let's find the difference between the theoretical standard deviation and the sample standard deviation:

Difference = Theoretical Standard Deviation - Sample Standard Deviation

          = 4.608 - 3.898 ≈ 0.71

Therefore, the difference between the theoretical standard deviation and the sample standard deviation is 0.71.

The difference between the theoretical standard deviation and the sample standard deviation is approximately 0.1026.

To find the difference between the theoretical standard deviation and the sample standard deviation, we need to calculate both of these values.

Sample: 15, 18, 15, 21, 20, 23, 14, 18, 23, 25

Parameter of the uniform distribution (minimum and maximum values): a = 13, b = 45

The theoretical standard deviation of a uniform distribution can be calculated using the formula:

σ_theoretical = (b - a) / √12

Substituting the given values:

σ_theoretical = (45 - 13) / √12

σ_theoretical ≈ 4.4496

Next, we need to calculate the sample standard deviation. The sample standard deviation measures the variability within the given sample.

Using the provided sample data, we can calculate the sample standard deviation using the following formula:

s = √(Σ(x - \(\bar{x}\))² / (n - 1))

Where:

x is each individual value in the sample,

\(\bar{x}\) is the sample mean,

n is the sample size.

Calculating the sample mean (\(\bar{x}\)):

\(\bar{x}\) = (15 + 18 + 15 + 21 + 20 + 23 + 14 + 18 + 23 + 25) / 10

\(\bar{x}\) = 19.2

Calculating the sample standard deviation (s):

s = √((15 - 19.2)² + (18 - 19.2)² + (15 - 19.2)² + (21 - 19.2)² + (20 - 19.2)² + (23 - 19.2)² + (14 - 19.2)² + (18 - 19.2)² + (23 - 19.2)² + (25 - 19.2)²) / (10 - 1)

s ≈ 4.347

Finally, we can calculate the difference between the theoretical standard deviation and the sample standard deviation:

Difference = σ_theoretical - s

Difference ≈ 4.4496 - 4.347

Difference ≈ 0.1026

Therefore, the difference between the theoretical standard deviation and the sample standard deviation is approximately 0.1026.

also, they want to spend $5 on packing space

and a ticket cost $27 per person.

Step two:

let the number of persons be x

and let the total amount to be spent be y

hence the inequality is

y≤ 5+ 27x

now for y= $275, let us find x

Answer:

Remember that the gradient is equivalent o the derivative evaluated in one point.

And remember that if we have a function like:

f(x)  a*x^n

The derivative is:

f'(x) = n*a*x^(n - 1)

Then knowing this, let's start:

a) y = x^2

the derivative is:

y' = 2*x

And we want to evaluate this in the point (3, 9), then we just need to replace x by 3.

y'(3) = 2*3 = 6

The gradient of y = x^2 at (3, 9) is 6.

b) y = -4*x^3

The derivative is:

y' = 3*(-4*x^2) = -12*x^2

And we want to evaluate this on (1, -4), then we need to replace x by 1.

y'(1) = -12*1^2 = -12

The gradient of y = -4*x^3 at (1, -4) is -12.

c) y = 2*x^4

The derivative is:

y' = 4*2*(x^3) = 8*x^3

And we want to evaluate this on (-1, 2), then we need to replace x by -1.

y'(-1) = 8*(-1)^3 = -8

The gradient of y = 2*x^4 at the point (-1, 2) is -8

d) y = 6*x

The derivative is:

y' = 6

We can see that here we do not have any dependence on x, so the gradient will be the same for all values of x, this means that the gradient at the point (2, 12) is 6.

Answer:

Step-by-step explanation:

To graph the equation 3(x - 2) = 5(x + 1), we can first simplify it by expanding the brackets:

3x - 6 = 5x + 5

Next, we can isolate the variable on one side of the equation. We can do this by subtracting 3x from both sides and adding 6 to both sides:

-11 = 2x

x = -11/2

Now we have the x-coordinate of the point where the graph of the equation intersects the x-axis. To find the y-coordinate of this point, we can substitute x = -11/2 into one of the original equations and solve for y:

3(x - 2) = 5(x + 1)

3(-11/2 - 2) = 5(-11/2 + 1)

-33/2 - 6 = -55/2 + 5

-33/2 - 6 + 55/2 = 5

-33/2 + 44/2 = 5

11/2 = 5

According to the nearest hundredth, the length of the wire in the photograph is 200 cm.

What in mathematics is a semicircle?

By dividing a circle into two halves along a diameter line, a semicircle is created, which is a half-circle.

The wire will be cut into four semicircles, each of which will have a circumference equal to its length.

Therefore, if one semicircle has a diameter of 32 cm, its radius is 32/2 cm, or 16 cm.

Right now, a circle's circumference equals 2*(pi)*(radius).

Since this is a semicircle, its circumference is equal to (pi)*(radius), or one-half of a circle.

The circumference of four semicircles is then equal to four * pi * radius.

Pi has a value of 22/7.

Thus, the length of the wire is 4*(22/7)*16 cm, which, when rounded to the nearest hundredth, is 200 cm.

In mathematics, a semicircle is a  one-dimensional locus of points that forms  half of a circle. It is a circular arc that  measures 180°.  It has only one line of symmetry.

In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure .

In other words ,The meaning of circumference is the distance around a circle or any curved geometrical shape. It is the one-dimensional linear measurement of the boundary across any two-dimensional circular surface.

According to figure

diameter of  all semi circle (d) = 32 cm.

so radius of  all semi circle r = \(\frac{32}{2}\) = 16 cm.

The quadratic equation from the graph is ax²+8=0.

From the given figure, the vertex (h, k)=(0, 0) and the point is (x, y)=(4, -8).

A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.

The vertex form of a quadratic function is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. The coefficient a determines whether the graph of a quadratic function will open upwards or downwards.

Now, f(x) = a(x - 0)² + 0

f(x) = ax²

Here, f(4)=-8

So, -8=ax²

John should survey at least 663,893 college graduates who took a statistics course in college in order to estimate the population standard deviation with a maximum margin of error of 50% and 99% confidence level.

To determine the sample size required to estimate the population standard deviation with a certain level of confidence and precision, we can use the following formula:

n = (z^2 * s^2) / E^2

where:

n = sample size

z = z-score corresponding to the desired confidence level (in this case, 99% confidence corresponds to a z-score of 2.576)

s = estimated population standard deviation

E = maximum allowable margin of error, as a proportion of the true population standard deviation (in this case, 50% of the true population standard deviation means E = 0.5)

We need to estimate the population standard deviation, s, in order to use this formula. If John does not have any prior knowledge about the population standard deviation, he can use a conservative estimate based on similar studies or data sources. Let's assume that he uses a conservative estimate of s = $10,000.

Substituting these values into the formula, we get:

n = (2.576^2 * 10,000^2) / (0.5^2)

n = 663,892.66

Rounding up to the nearest whole number, John should survey at least 663,893 college graduates who took a statistics course in college in order to estimate the population standard deviation with a maximum margin of error of 50% and 99% confidence level.

This means y = mx+b updates to y = 7x+b

Plug a point like (1,7) into that equation to solve for b.

y = 7x+b

7 = 7*1+b

7 = 7+b

7-7 = b

0 = b

b = 0

We go from  y = 7x+b to  y = 7x+0

That simplifies to the final answer of   y = 7x
