The mean (μ) for the given binomial distribution is 0.50.

To calculate the mean (μ) of a binomial distribution, we multiply the number of trials (n) by the probability of success in a single trial (π). Let's examine each scenario in detail:

a. When n = 5 and π = 0.10:

μ = 5 * 0.10

  = 0.50

For this binomial distribution, with 5 trials and a success probability of 0.10, the mean (μ) is 0.50. This means that, on average, we would expect to have 0.50 successes per trial.

b. When n = 3 and π = 0.40:

μ = 3 * 0.40

  = 1.20

In this case, the mean (μ) of the binomial distribution is 1.20. It indicates that, on average, there would be 1.20 successes per trial when there are 3 trials and a success probability of 0.40.

c. When n = 5 and π = 0.50:

μ = 5 * 0.50

  = 2.50

For a binomial distribution with 5 trials and a success probability of 0.50, the mean (μ) is 2.50. This means that, on average, we would expect to have 2.50 successes per trial.

d. When n = 3 and π = 0.80:

μ = 3 * 0.80

  = 2.40

In this scenario, the mean (μ) of the binomial distribution is 2.40. It suggests that, on average, we would expect to have 2.40 successes per trial when there are 3 trials and a success probability of 0.80.

The mean (μ) provides a measure of the central tendency or the average number of successes in a binomial distribution based on the given parameters.

Step-by-step explanation:

Answer:

[tex]\frac{db}{dt}=\frac{20\sqrt{69}}{69}\approx2.4077\text{ ft/s}[/tex]

Step-by-step explanation:

We know that the ladder is 13 feet long.

We also know that the top of the ladder is slipping down at a rate of 2ft/s.

And we want to find the rate at which the foot of the ladder is moving away when the top is 10 feet above the ground.

We can use the Pythagorean Theorem for this problem:

[tex]a^2+b^2=c^2[/tex]

Let's let a be the leg by the wall, and b be the leg on the ground.

Our hypotenuse is 13 and it stays 13. So, let's substitute 13 for c:

[tex]a^2+b^2=(13)^2=169[/tex]

Now, let's take the derivative of both sides with respect to t:

[tex]\frac{d}{dt}[a^2+b^2]=\frac{d}{dt}[169][/tex]

Evaluate. Use implicit differentiation:

[tex]2a\frac{da}{dt}+2b\frac{db}{dt}=0[/tex]

We know that the top of the ladder is slipping down at a rate of 2ft/s. So, da/dt is -2 (it's negative because it's slipping downwards).

We want to find db/dt when the top is 10 feet above the ground. So, substitute 10 for a.

Since a is 10 and we know that c stays constant at 13, we can figure out b using the Pythagorean Theorem:

[tex]10^2+b^2=13^2[/tex]

Evaluate:

[tex]100+b^2=169[/tex]

Solve for b:

[tex]b^2=69\\b=\sqrt{69}[/tex]

So, substitute -2 for da/dt, 10 for a, and √69 for db/dt. This yields:

[tex]2(10)(-2)+2(\sqrt{69})(\frac{db}{dt})=0[/tex]

Solve for db/dt. Multiply:

[tex]-40+2(\sqrt{69})(\frac{db}{dt})=0[/tex]

Add 40 to both sides:

[tex]2\sqrt{69}(\frac{db}{dt})=40[/tex]

Divide both sides by 2√69:

[tex]\frac{db}{dt}=\frac{20}{\sqrt{69}}[/tex]

Rationalize:

[tex]\frac{db}{dt}=\frac{20\sqrt{69}}{69}\approx2.4077\text{ ft/s}[/tex]

So, the foot will be moving at approximately 2.4077 feet per second.

How do we get a bigger number? Subtracting or dividing will just make it smaller. So we have to multiply. We need it about 4 times bigger (3 x 28 = 84, 4 x 28 .

The correct option is a) $5161.24

To evaluate the expression P(1+rt) with the given values:

P = 1575

r = 0.055

t = 168/365

First, let's calculate rt:

rt = 0.055 * (168/365)

= 0.0252836 (rounded to 7 decimal places)

Now, substitute the values into the expression P(1+rt):

P(1+rt) = 1575 * (1 + 0.0252836)

= 1575 * 1.0252836

= 1615.85846 (rounded to 5 decimal places)

The result is approximately $1615.86.

Therefore, the correct option is a) $5161.24

Answer:

Step-by-step explanation:

Without the 5% interest it would take 2 months to pay it off but with the 5% interest added that's going to 5% of whatever the balance is.

After her 1rst payment of 60$ she will have 66$ left to pay: 120(1/20)+6-60

After her 2nd payment of 60$ she will have 9.3$ left to pay: 66(1/20)+ 3.3-60

so basically 2 payments of $60 and one payment of $0.47

The company should charge approximately $33.33 per unit in order to sell 4500 units, based on the given assumptions.

To determine the price per unit that the company should charge in order to sell 4500 units, we need additional information such as the total cost and desired profit margin. The price per unit can be calculated using the following formula:

Price per unit = (Total cost + Desired profit) / Number of units

Let's assume that the total cost is $100,000 and the desired profit is $50,000. We can substitute these values into the formula to find the price per unit:

Price per unit = ($100,000 + $50,000) / 4500

Price per unit = $150,000 / 4500

Price per unit ≈ $33.33

It's important to note that the actual price per unit may vary depending on the specific cost and profit margin considerations of the company.

Answer:

Step-by-step explanation:

I had the same q on my quiz

The forecasted registrations for years 2 through 12 using exponential

smoothing, with a smoothing constant (α) of 0 and a starting forecast of 4.00 for year 1 are:

Year | Forecasted registrations

------- | --------

2 | 4.00

3 | 4.00

4 | 4.00

5 | 4.00

6 | 4.00

7 | 4.00

8 | 4.00

9 | 4.00

10 | 4.00

11 | 4.00

12 | 4.00

Exponential smoothing is a forecasting method that uses past data to predict future values. The smoothing constant (α) determines how much weight is given to the most recent data. In this case, we are using a smoothing constant of 0, which means that all of the weight is given to the most recent data. This means that the forecasted registrations for all years will be the same as the starting forecast of 4.00.

Here is the formula for exponential smoothing:

```

Forecasted registrations = α * most recent data + (1 - α) * previous forecast

```

In this case, α = 0, so the formula becomes:

```

Forecasted registrations = most recent data

```

Since the most recent data is always 4.00, the forecasted registrations will always be 4.00.

Answer: B. 12-4=f

Step-by-step explanation: The correct answer is B. We can use subtraction to find the number of pieces of fruit that were taken out of the bag, which is 12 - 4 = 8. Then, we can add the number of pieces of fruit that remained to the number of pieces that were taken out to get the total number of pieces that were in the bag to start, which is 8 + 4 = 12.

Therefore, there were 12 pieces of fruit in the bag to start.

Decreasing the sample size from 750 to 375 would multiply the standard deviation by √2. The correct answer is (b) √2.

The sample size is the number of individuals in a study. If the population is extremely large, the sample size should be larger than if it were smaller. As a result, the larger the sample size, the better, since it leads to higher accuracy and a lower margin of error. For example, let’s say you want to know the proportion of people who wear glasses. If you only ask three people, you may get lucky and find all three wear glasses or unlucky and get none of them to wear glasses. If you ask 30 people, your estimate of the proportion of people who wear glasses will be much better.

The effect of sample size on standard deviation: Standard deviation measures how much spread there is in the data. Larger samples provide better estimates of the population, and therefore, the standard deviation is smaller for larger samples than for smaller ones. This is because a larger sample will have more data points, which will help to better estimate the true population standard deviation. Decreasing the sample size will not only make the standard deviation larger but also introduce more variability in the data. In fact, the standard deviation will be multiplied by the square root of the ratio of the two sample sizes. In this case, it will be multiplied by √2. Therefore, the answer is (b) √2.
