There is a 75.40% chance that the sample mean X will be more than 0.5 away from the population mean μ.

Let X be the random variable representing the sample mean of a random sample of size 36 selected from a population with mean μ=44 and standard deviation σ=8.

The Central Limit Theorem (CLT) states that, under certain conditions, the distribution of the sample mean X can be approximated by a normal distribution with mean μ and standard deviation σ/√(n), where n is the sample size. Since the sample size is 36, we can use this approximation.

The probability that X is more than 0.5 away from the population mean can be calculated as follows:

P(|X-μ| > 0.5) = P((X-μ)/ (σ/√(n)) > (0.5) / (σ/√(n))) + P((X-μ)/ (σ/√(n)) < (-0.5) / (σ/√(n)))

Using the standard normal distribution table, we can find the corresponding probabilities for each term on the right-hand side of the equation. We have:

P(Z > 0.3125) + P(Z < -0.3125)

where Z is a standard normal random variable with mean 0 and standard deviation 1.

Using the standard normal distribution table, we can find that P(Z > 0.3125) = 0.3770 and P(Z < -0.3125) = 0.3770.

Therefore, the approximate probability that X will be more than 0.5 away from the population mean is:

P(|X-μ| > 0.5) = 0.3770 + 0.3770 = 0.7540

In terms of percentage, we can rewrite it as,

P(|X-μ| > 0.5) = 0.7540*100 = 75.40%

Answer:

y = 0.8x + 10

Step-by-step explanation:

From the given graph,

Graphed line passes through two points (0, 10) and (50, 50)

Let the equation of the given line is,

y = mx + b

Where m = slope of the line

b = y-intercept

Since slope 'm' = \(\frac{y_2-y_1}{x_2-x_1}\)

m = \(\frac{50-10}{50-0}\)

m = \(\frac{4}{5}\) = 0.8

y-intercept of the line 'b' = 10

Therefore, equation of the line of best fit will be,

y = 0.8x + 10

Answer:

$180.00

Step-by-step explanation:

The painting is rectangular and it measures 1 meter by 2 meters. The frame shop charges $30.00 per meter for a wooden frame.

To find the cost, we need to find the perimeter of the painting and then multiply it by the cost of a wooden frame per meter.

The perimeter of a rectangle is:

P = 2(L + B)

P = 2(1 + 2) = 2 * 3 = 6 m

The cost of the frame is therefore:

Answer:

Mean: \(\bar x = 40.61\)

\(Median =40.2\)

\(Mode = 43.4\)

Step-by-step explanation:

Given

See attachment for data

Solving (a): The mean

Mean is calculated as:

\(\bar x = \frac{\sum x}{n}\)

From the attached:

\(n = 14\)

So, the mean is:

\(\bar x = \frac{43.4+43.4+43.4+43.1+43.2+40.2+40.2+40.1+40.3+39.44+39.17+38.03+38.19+36.45}{14}\)

\(\bar x = \frac{568.58}{14}\)

\(\bar x = 40.61\)

Solving (b): The median

\(n = 14\); this is an even number. So, the median is:

\(Median = \frac{1}{2}(n+1)\)

\(Median = \frac{1}{2}(14+1)\)

\(Median = \frac{1}{2}(15)\)

\(Median = 7.5th\)

This implies that the median is the average of the 7th and 8th item.

Next, is to order the data (in ascending order): 36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.

The 7th and 8th items are: 40.2 and 40.2

The median is:

\(Median = \frac{1}{2}(40.2 + 40.2)\)

\(Median = \frac{1}{2}*80.4\)

\(Median =40.2\)

Solving (c): The mode

43.4 has the highest number of occurrence.

So:

\(Mode = 43.4\)

The given differential equation is y'(x) = 1/200(cos(x) - y) y(0)

Using implicit Euler's method, we get:

y(i+1) = y(i) + hf(x(i+1), y(i+1))

Where,f(x, y) = 1/200(cos(x) - y)

At x = 0, y = y(0)

Using h = 0.2, we have,

x(1) = x(0) + h

= 0 + 0.2

= 0.2

y(1) = y(0) + h f(x(1), y(1))

Substituting the values, we get;

y(1) = y(0) + 0.2 f(x(1), y(1))

y(1) = y(0) + 0.2 (1/200) (cos(x(1)) - y(1)) y(0)

By simplifying and substituting the values, we get;

y(1) = 0.9917217

Now, x(2) = x(1) + h

= 0.2 + 0.2

= 0.4

Similarly, we can calculate y(2), y(3), y(4) and y(5) as given below;

y(2) = 0.9858992

y(3) = 0.9801913

y(4) = 0.9745986

y(5) = 0.9691222

Now, we have to find y(0.8).

Since 0.8 lies between 0.6 and 1, we can use the following formula to calculate y(0.8).

y(0.8) = y(0.6) + [(0.8 - 0.6)/(1 - 0.6)] (y(1) - y(0.6))

Substituting the values, we get;

y(0.8) = 0.9758693

The exact solution is given by;

y(x) = cos(x) + 0.005 sin(2x) - e^(-200x^2)

At x = 0.8, we have;

y(0.8) = cos(0.8) + 0.005 sin(1.6) - e^(-200(0.8)^2)

y(0.8) = 0.9745232

Therefore, the true error is given by;

True error = y(exact) - y(numerical)

True error = 0.9745232 - 0.9758693

True error = -0.0013461

Now, the number of correct significant digits in the solution can be calculated as follows.

The number of correct significant digits = -(log(abs(True error))/log(10))

A number of correct significant digits = -(log(abs(-0.0013461))/log(10))

Number of correct significant digits = 2

Therefore, the true error is -0.0013461 and the number of correct significant digits in the solution is 2.

The distance along the unit circle between any two successive 8th roots of 1 is c) π/4.

To find the distance along the unit circle between any two successive 8th roots of 1, we can consider the concept of angular displacement.

Each 8th root of 1 represents a point on the unit circle that is evenly spaced by an angle of 2π/8 = π/4 radians.

Starting from the point corresponding to 1 on the unit circle, we can move π/4 radians to reach the first 8th root of 1. Moving π/4 radians further will bring us to the second 8th root of 1, and so on.

Since we are moving by π/4 radians for each successive 8th root of 1, the distance between any two successive 8th roots of 1 is π/4 radians.

Therefore, the correct answer is option c. π/4.

The nth term of this sequence will be 2 raised to the power of 2 raised to the power of n - 2.

(a) Here, the sequence is formed as follows;

adding 3 to the previous term of the sequence and then the term number, n.

So, the nth term of this sequence will be n² + 2n.

Thus the next three terms are 123, 146, 171.

(b) Here, the sequence is formed as follows;

adding 4 to the previous term of the sequence.

So, the nth term of this sequence will be 4(n - 1) + 7. Thus the next three terms are 47, 51, 55.

(c) Here, the sequence is formed as follows;

For each integer in the list, convert it to binary. Drop the first digit from the first integer (since it is 1), then concatenate the resulting strings.

So, the nth term of this sequence will be the integer whose binary representation is obtained by concatenating the binary representation of the previous integer in the sequence with that of 1. Thus the next three terms are 1100, 1101, 1110.

(d) Here, the sequence is formed as follows;

the kth term of the sequence is the smallest prime number that has not yet appeared in the sequence, and then this prime number is repeated a number of times equal to the kth term of the sequence.

So, the nth term of this sequence will be the smallest prime number that has not yet appeared in the sequence for n - 1 times, repeated n - 1 times. Thus the next three terms are 7, 7, 7.

(e) Here, the sequence is formed as follows;

the kth term of the sequence is 2^(k-1) - 1.

So, the nth term of this sequence will be 3^n - 1.

Thus the next three terms are 59048, 177146, 531442.

(f) Here, the sequence is formed as follows;

the kth term of the sequence is the product of the first k odd primes.

So, the nth term of this sequence will be the product of the first n odd primes.

Thus the next three terms are 654729075, 12300270015015, 32589158477190044730.

(g) Here, the sequence is formed as follows;

the kth term of the sequence is the parity of the sum of the previous k terms.

So, the nth term of this sequence will be 1 if the number of 1s among the first n terms of the sequence is odd, and 0 otherwise. Thus the next three terms are 1, 1, 1.

(h) Here, the sequence is formed as follows;

the kth term of the sequence is 2 raised to the power of the kth term of the sequence that immediately precedes it.

So, the nth term of this sequence will be 2 raised to the power of 2 raised to the power of n - 2.

Thus the next three terms are 18446744073709551616, 3.402823669209385e+38, 1.1579208923731617e+77.

The inverse Laplace transform of F(s) is:

\(f(t) = e^(-t)\)

To find the inverse Laplace transform of each function, we need to express them in terms of known Laplace transforms. Here are the solutions for each function:

a)

\(F(s) = \large{\frac{2e^{-0.5s}}{s^2-6s+9}}\)

To find the inverse Laplace transform, we first need to factor the denominator of F(s). The denominator factors as (s - 3)². Therefore, we can rewrite F(s) as:

\(F(s) = \large{\frac{2e^{-0.5s}}{(s-3)^2}}\)

Now, we know that the Laplace transform of eᵃᵗ is 1/(s - a). Therefore, the inverse Laplace transform of

\(e^(-0.5s) \: is \: e^(0.5t).\)

Applying this, we get:

\(f(t) = 2e^(0.5t) * t \\

b) F(s) = \large{\frac{s-1}{s^2-3s+2}}\)

We can factor the denominator of F(s) as (s - 1)(s - 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{s-1}{(s-1)(s-2)}}\)

Simplifying, we have:

\(F(s) = \large{\frac{1}{s-2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(2t) \\

c) F(s) = \large{\frac{s-1}{s^2+s-2}}

\)

We factor the denominator of F(s) as (s - 1)(s + 2). The expression becomes:

\(F(s) = \large{\frac{s-1}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{1}{s+2}}\)

The Laplace transform of 1 is 1/s. Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(-2t) \\

d) F(s) = \large{\frac{e^{-s}(s-1)}{s^2+s-2}}\)

We can factor the denominator of F(s) as (s - 1)(s + 2). Now, we rewrite F(s) as:

\(F(s) = \large{\frac{e^{-s}(s-1)}{(s-1)(s+2)}}\)

Canceling out the (s - 1) terms, we have:

\(F(s) = \large{\frac{e^{-s}}{s+2}}\)

The Laplace transform of

\(e^(-s) \: is \: 1/(s + 1).\)

Therefore, the inverse Laplace transform of F(s) is:

\(f(t) = e^(-t)\)

The absolute value function f(x) = |x| is defined to be the distance of x from zero on the number line. In this case, we have f(x) = 2|x + 4|, where the entire function is scaled by a factor of 2.The absolute value function is continuous for all real values of x. This means that there are no x-values at which the function has any "breaks" or "holes" in its graph. It smoothly extends across the entire real number line.
However, the absolute value function is not differentiable at points where it has a sharp corner or a "kink." In this case, the absolute value function f(x) = 2|x + 4| has a kink at x = -4. At this point, the function changes its slope abruptly, and thus, it is not differentiable.In summary, the absolute value function f(x) = 2|x + 4| is continuous for all x-values but not differentiable at x = -4.

The statement about the relationship of the data in the table is indicated in the option;

A proportional relationship is one in which one variable (the output variable) is a constant multiple of the input variable, such that a point on the graph of ordered pairs of variable is the point (0, 0), which is the origin.

The points on the graph are; (1, 3.5), (2, 4.5), (3, 5,5)

The slope of the graph is therefore; (4.5 - 3.5)/(2 - 1) = 1

The equation in point-slope form is therefore; y - 3.5 = x - 1

y = x - 1 + 3.5 = x + 2.5

y = x + 2.5

The equation is a linear relationship. The equation is in the form; y = m·x + c, with the slope m = 1 and a y-intercept, c = 2.5

The y-intercept is 2,5, therefore, the graph does not pass through the origin.

The relationship of the line passing through the points, is a linear relationship. The line passing through the points does not pass through the origin, therefore the relationship is not a proportional relationship
