The step of make a decision of hypothesis testing is where we state that we retain or reject the null hypothesis.

What us hypothesis testing?

A statistical hypothesis test is a technique for determining if the available data are sufficient to support a specific hypothesis. We can make decisions regarding population parameters through hypothesis testing.

Early kinds of hypothesis testing were utilized in the 1700s, while the practice gained popularity in the early 20th century. John Arbuthnot (1710) is credited with developing the method originally, and Pierre-Simon Laplace (1770s) is credited with developing it further.

The process of deciding to reject or retain the null hypothesis is called significance. and the step of hypothesis testing, in which we state that we retain or reject the null hypothesis is the step in which we make a decision.

Answer:

Please refer to the attached image for the graph of g(x).

Step-by-step explanation:

First of all, let us find the value of g(x).

Given that:

\(f(x) =2x-5\) and

\(g(x) = f(x+1)\)

To find: The graph of g(x) = ?

Solution:

\(f(x+1)\) means we replace  'x' with 'x+1' and we get g(x).

Let us replace x with x+1 in f(x):

\(f(x+1) = 2(x+1)-5\\\Rightarrow f(x+1) = 2x+2-5\\\Rightarrow f(x+1) = 2x-3\\\therefore g(x) = 2x-3\)

Now let \(y=g(x) =2x-3\)

Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g(x).

Putting x = 0,

\(y=2\times0-3\\\Rightarrow y =-3\)

So, one point is A(0,-3)

Now, let us put y = 0 and find out x.

\(0=2x-3\\\Rightarrow x=\dfrac{3}{2}\)

So, second point is \(B(\frac{3}{2},0)\).

Now, let us plot A and B then extend the line joining AB.

Please refer to the attached image for the graph of function:

Hey there!

To solve this problem, we will be using Trigonometric Ratio. Trigonometry is always helpful when it comes to finding a missing side with specific measure/angle.

1. Cosine Ratio

2. Adjacent and Hypotenuse

Hope you understand this topic! If not, feel free to ask!

3. Solve The Problem

Therefore, the equation for the problem is:

\( \large{cos62 \degree = \frac{x}{12} }\)

*cos is the short form of cosine*

At this part, we need a calculator to find the value of cos62 degrees. That's because it is not a degree like 0, 30, 45, 60 and 90 which can be found without a calculator.

When we put cos62 in a calculator, make sure to put it in degree mode since a calculator has two modes which are degree and radian.

When we put cos62 in, we should get 0.46947156... Because you want a one decimal place, we round the value up to the nearest tenth as we get 0.5 because 6 is greater than 5 and should be rounded up and not down. That makes the equation to:

\( \large{0.5 = \frac{x}{12} }\)

Oh well! Finally to the equation part. Whenever you have to solve the equation that has decimal numbers in it, the best way to deal with decimal numbers is to make them into a whole number or integer. But how? Simply multiply the whole equation by 10. Because 0.5×10 is 5 thus 0.5 becomes an integer after multiplying 10.

\( \large{0.5 \times 10 = \frac{x}{12} \times 10} \\ \large{5 = \frac{10x}{12} }\)

10x/12 can be simplified again.

\( \large{5 = \frac{5x}{6} }\)

Then we isolate x-value by multiplying 6 the whole equation.

\( \large{5 \times 6 = \frac{5x}{6} \times 6} \\ \large{30 = 5x} \\ \large{x = 6}\)

Huh, that's awkward! We want the answer in a 1 decimal place but seems like the answer for this is 6. Why? Well that is not an exact answer, but more like an approximation. Because the value of cos62 degree is actually a repeating decimal and doesn't have exact value.

When we put the equation cos62 = x/12 in the equation and solve. It appears that the the answer is 5.63365875. Because we round up to nearest tenth, it gives an approximation to 5.63365875 instead.

Hence, the equation and value above is just a rounded to the whole number from 5.63365875.

Because you want a one place decimal. Hence,

4. Final Answer

By multiplying the duration of each episode by the number of episodes watched and then converting minutes to days, we find that you spent around 2.285 days of your life watching your favorite TV show.

To calculate the total number of minutes spent watching the show, multiply the duration of each episode (53 minutes) by the number of episodes watched (62). This gives us 3296 minutes.

Answer:

Start with equation,

         y''(x) = f(x) = 6y/(10x-x²)               about point x₀ = 5

Then,

       y(x) = a₀ + a₁(x-5) + a₂(x-5)²+ a₃(x-5)³ + a₄(x-5)⁴...….

by inspection,

           y(5) = a₀      and       y'(5) = a₁

then,

y''(5) = 6a₀/(50-25) = 6a₀/25              

y'''(x) = 6y'/(10x-x2) - 6y(10-2x)/(10x-x2)2

then,                      

                              y'''(5) = 6a₁/25 - 0 = 6a₁/25                

y''''(x) = 6y''/(10x-x2) -12y'(10-2x)/(10x-x2)² + 12y/(10x-x2)² + 12y(10-2x)2/(10x-x2)³

then,

    y''''(5) = (6/25)(6a₀/25) + 0 + 12a₀/625 + 0

              = 48a₀/625

So,

Given that the discharge current decreases to 27% of its initial value in 1.40 ms, we can use the equation of discharge current:

The capacitance of the capacitor is 0 F.

Part A:

Given that the discharge current decreases to 27% of its initial value in 1.40 ms, we can use the equation of discharge current:

I = I₀e^(-t/RC)

Here,

I₀ = initial current

R = resistance

C = capacitance

t = time

We are given that the current is 27% of the initial value, so the equation becomes:

0.27 = \(1e^(-1.40*10^-3/RC)\)

Simplifying the equation, we find:

RC =\(3.28* 10^-3 s\)   ----(1)

Part B:

The time taken to discharge a capacitor through a resistance R is given by:

t = RC ln (Vc/V₀)

where Vc = voltage across the capacitor at time t and V₀ = initial voltage across the capacitor.

Substituting the values, we have:

\(1.40*10^-3\) = C*90 ln (0/100)

Since a fully discharged capacitor has a voltage of 0, we set Vc = 0. Thus, the equation becomes:

\(1.40*10^-3\)= C*90 ln (0)

The natural logarithm of 0 is negative infinity. Therefore, the equation becomes:

\(1.40*10^-3\)= C*90*(-infinity)

Simplifying further, we find:

C = 0

Thus, the value of capacitance is 0 F.

Therefore, the maximum displacement of the particle is 4 units, and it occurs at time t = 1.

To find the maximum displacement, we need to first determine the particle's velocity and acceleration.

The velocity of the particle is given by the derivative of its position function:

\(v(t) = y'(t) = 3t^2 - 12t + 9\)

The acceleration of the particle is given by the derivative of its velocity function: a(t) = v'(t) = 6t - 12

Now, to find the maximum displacement, we need to find the time at which the particle comes to rest.

This occurs when its velocity is zero:

\(3t^2 - 12t + 9 = 0\)

Simplifying this equation, we get:

\(t^2 - 4t + 3 = 0\)

This quadratic equation factors as:

(t - 1)(t - 3) = 0

So the particle comes to rest at t = 1 or t = 3.

Next, we need to determine whether the particle is at a maximum or minimum at each of these times.

To do this, we look at the sign of the acceleration:

When t = 1, a(1) = 6(1) - 12 = -6, which is negative.

Therefore, the particle is at a maximum at t = 1.

When t = 3, a(3) = 6(3) - 12 = 6, which is positive.

Therefore, the particle is at a minimum at t = 3.

Finally, we need to find the displacement of the particle at each of these times:

\(y(1) = 1^3 - 6(1)^2 + 9(1) = 4\)

\(y(3) = 3^3 - 6(3)^2 + 9(3) = 0.\)

Simplification involves applying rules of computation and algebra to remove gratuitous terms, factors, or operations from an expression.

Then,

To calculate how much longer it takes Ahmed to run a afar than Tonya, we need to find the difference between their handling times.

First, we need to convert the times to a common unit. Let's convert the times to seconds,

Ahmed's time 8 twinkles 30 seconds = ( 8 x 60) 30 = 510 seconds

Tonya's time 7 twinkles 45 seconds = ( 7 x 60) 45 = 465 seconds

Using formula of cylinder

\(V=\pi r^2h\)

Where, r = radius

A)  annual percentage increase in the winner's check over this period is approximately 11595652.17%.

B)   if the winner's prize increases at the same rate, it will be approximately $3,651,682,684.48 in 2055.

a. To find the annual percentage increase in the winner's check over this period, we can use the formula:

Annual Percentage Increase = ((Final Value - Initial Value) / Initial Value) * 100

First, let's calculate the annual percentage increase in the winner's check from 1899 to 2020:

Initial Value = $23
Final Value = $2,670,000

Annual Percentage Increase = (($2,670,000 - $23) / $23) * 100

Now, we can calculate this value using the given formula:

Annual Percentage Increase = ((2670000 - 23) / 23) * 100 = 11595652.17%

Therefore, the annual percentage increase in the winner's check over this period is approximately 11595652.17%.

b. If the winner's prize increases at the same rate, we can use the annual percentage increase to calculate the prize money in 2055. Since we know the prize money in 2020 ($2,670,000), we can use the formula:

Future Value = Initial Value * (1 + (Annual Percentage Increase / 100))^n

Where:
Initial Value = $2,670,000
Annual Percentage Increase = 11595652.17%
n = number of years between 2020 and 2055 (2055 - 2020 = 35)

Now, let's calculate the prize money in 2055 using the given formula:

Future Value = $2,670,000 * (1 + (11595652.17 / 100))^35

Calculating this value, we find:

Future Value = $2,670,000 * (1 + 11595652.17 / 100)^35 ≈ $3,651,682,684.48

The probability that the system has a type 2 defect given that it has a type 1 defect is 0.1. the probability that the system has exactly one type is approximately 0.5048.the probability that the system does not have the third type of defect given that it has both the first two types of defects is 0.9375

To solve the given probabilities, we can use the rules of probability, including the conditional probability and the inclusion-exclusion principle.

(a) To find the probability that the system has a type 2 defect given that it has a type 1 defect, we can use the conditional probability formula:

P(A₂ | A₁) = P(A₂ ∩ A₁) / P(A₁)

From the given probabilities:

P(A₁) = 0.10

P(A₂ ∪ A₁) = P(A₁) + P(A₂) - P(A₁ ∩ A₂) = 0.11

P(A₂ ∩ A₁) = P(A₂ ∪ A₁) - P(A₁) = 0.11 - 0.10 = 0.01

Using the formula:

P(A₂ | A₁) = P(A₂ ∩ A₁) / P(A₁) = 0.01 / 0.10 = 0.1

Therefore, the probability that the system has a type 2 defect given that it has a type 1 defect is 0.1.

(b) To find the probability that the system has all three types of defects given that it has a type 1 defect, we can use the conditional probability formula:

P(A₁ ∩ A₂ ∩ A₃ | A₁) = P(A₁ ∩ A₂ ∩ A₃) / P(A₁)

From the given probabilities:

P(A₁) = 0.10

P(A₁ ∩ A₂ ∩ A₃) = 0.01

Using the formula:

P(A₁ ∩ A₂ ∩ A₃ | A₁) = P(A₁ ∩ A₂ ∩ A₃) / P(A₁) = 0.01 / 0.10 = 0.1

Therefore, the probability that the system has all three types of defects given that it has a type 1 defect is 0.1.

(c) To find the probability that the system has exactly one type of defect given that it has at least one type of defect, we can use the conditional probability formula:

P(Exactly one type of defect | At least one type of defect) = P(Exactly one type of defect ∩ At least one type of defect) / P(At least one type of defect)

From the given probabilities:

P(A₁ ∪ A₂ ∪ A₃) = 1 - P(no defects) = 1 - P(A₁ᶜ ∩ A₂ᶜ ∩ A₃ᶜ)

             = 1 - (1 - P(A₁)) * (1 - P(A₂)) * (1 - P(A₃))

             = 1 - (1 - 0.10) * (1 - 0.07) * (1 - 0.05)

             = 1 - (0.90) * (0.93) * (0.95)

             ≈ 0.1997

P(Exactly one type of defect ∩ At least one type of defect) = P(At least one type of defect) - P(No defects)

                                                          = P(A₁ ∪ A₂ ∪ A₃) - P(A₁ᶜ ∩ A₂ᶜ ∩ A₃ᶜ)

                                                          = 0.1997 - 0.899

                                                          ≈ 0.1007

Using the formula:

P(Exactly one type of defect | At least one type of defect) = P(Exactly one type of defect ∩ At least one type of defect) /

P(At least one type of defect)

                                                          = 0.1007 / 0.1997

                                                          ≈ 0.5048

Therefore, the probability that the system has exactly one type of defect given that it has at least one type of defect is approximately 0.5048.

(d) To find the probability that the system does not have the third type of defect given that it has both the first two types of defects, we can use the conditional probability formula:

P(A₃ᶜ | A₁ ∩ A₂) = 1 - P(A₃ | A₁ ∩ A₂)

From the given probabilities:

P(A₁ ∩ A₂ ∩ A₃) = 0.01

P(A₃ | A₁ ∩ A₂) = P(A₁ ∩ A₂ ∩ A₃) / P(A₁ ∩ A₂)

                = 0.01 / P(A₁ ∩ A₂)

                = 0.01 / (P(A₁) + P(A₂) - P(A₁ ∪ A₂))

                = 0.01 / (0.10 + 0.07 - 0.01)

                = 0.01 / 0.16

                ≈ 0.0625

Using the formula:

P(A₃ᶜ | A₁ ∩ A₂) = 1 - P(A₃ | A₁ ∩ A₂) = 1 - 0.0625 = 0.9375

Therefore, the probability that the system does not have the third type of defect given that it has both the first two types of defects is 0.9375.

The answer is 2.6825  cm, which is not one of the given options. Therefore, the correct answer is E. none of these.

The bulk modulus, B is defined as:

B = (P / ΔV / V), where P is the pressure applied, ΔV is the change in volume, and V is the original volume.

For a cube, the change in volume, ΔV is related to the change in length, ΔL by:

\(\sf \Delta V = \Delta L^3\).

Given that the cube has 2.0 cm sides, the original volume, V is:

\(\sf V = (2.0 \ cm)^3 = 8.0 \ cm^3\).

The pressure applied is \(\sf P = 2.0 \times 10^5\) Pa and the bulk modulus is \(\sf B = 4.7 \times 10^5 \ N/m^2\).

We can rearrange the bulk modulus formula to solve for ΔL as:

\(\sf \Delta L = \huge \text(\dfrac{P}{B} \huge \text) \times \dfrac{V}{3}\).

Substituting the values, we get:

\(\sf \Delta L = (2.0 \times 10^5 \ \dfrac{Pa}{4.7} \times 10^5\ N/m^2) \times \dfrac{8.0 \ cm^3}{3} = 0.6825 \ cm\)

Therefore, the final length of any side of the cube is:

The probability that the customer is a good risk is 0.70 and the probability that the customer is not a poor risk is 0.957.

To calculate the probability of the customer being a good risk, we need to divide the total number of good risk customers (7732) by the total number of customers (11,102). This gives us 7732/11102 = 0.7000. To calculate the probability of the customer not being a poor risk, we can subtract the total number of poor risk customers (949) from the total number of customers (11,102). This gives us 11102-949 = 10,153. We then divide this number by the total number of customers, giving us 10,153/11,102 = 0.9571. Therefore, the probability that the customer is a good risk is 0.70 and the probability that the customer is not a poor risk is 0.9571.
