The principal amount calculated as from the given data was fount out to be $895.

The formula to calculate interest rate is ,

Interest = Principal x Rate x Time which can also be written as,

I=PRT

therefore to find principal,

P= I/(RT)

P= 150.36/( 1.4% x 12)

P= 150.36/ (21/125)

P= 895

Principal amount is the amount which one invests on something for a given period of time at a fixed rate . The amount which the person receives is known as the profit.

In finance interest is the payment of an amount other than the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or deposit-taking financial institution.

Livingston is approximately 8.2 miles away from Chandler's house, measured in a straight line.

To find the distance between Livingston and Chandler's house, we can use the Pythagorean theorem because we have a right triangle formed by Springtown, Chandler's house, and Livingston.

Let's assign variables to the distances:

Let x be the distance from Livingston to Chandler's house (in miles).

Let y be the distance from Springtown to Chandler's house (in miles).

Given information:

Springtown is 6 miles away from Chandler's house (y = 6).

Livingston is 10 miles away from Springtown.

Using the Pythagorean theorem:

According to the theorem, the square of the hypotenuse (the distance between Livingston and Chandler's house) is equal to the sum of the squares of the other two sides.

Applying the theorem, we have:

x² = y² + (10)²

x² = 6² + 10²

x² = 36 + 100

x² = 136

Taking the square root of both sides:

x = √136

x ≈ 11.66

Therefore, Livingston is approximately 8.2 miles away from Chandler's house, measured in a straight line.

The answer is: A) The data support the researchers' belief that night owls have better dream recall than early birds. B) we can be 92% confident that the true difference in mean number of dreams recalled per week between night owls and early birds is between 1.87 and 2.63.

A) These are the alternative and null hypotheses:

H0: μE = μN (the mean number of dreams recalled each week is the same for early birds and night owls) (the mean number of dreams recalled per week is the same for early birds and night owls)

Ha: μE < μN (the mean number of dreams recalled each week is smaller for early birds than for night owls) (the mean number of dreams recalled per week is lower for early birds than for night owls)

Using the following formula, we can run a two-sample t-test with unequal variances:

t = [(sN2 / nN) + (sE2 / nE)] / sqrt[(xN - xE)]

where nN and nE are the sample sizes for night owls and early birds, respectively, and xN and sN and xE and sE are the sample means and standard deviations for night owls and early birds, respectively.

When we enter the values, we obtain:

t = (9.55 - 7.26) / sqrt[(5.88^2 / 100) + (6.94^2 / 100)] = 5.01

The data are consistent with the researchers' hypothesis that night owls are more capable of remembering their dreams than early birds.

B) We can use the following formula to determine the confidence interval:

CI is equal to (xN - xE) t/2 * sqrt[(sN / nN) + (sE / nE)].

where t/2 is the t-value for the required level of confidence and degrees of freedom, and xN, xE, sN, sE, nN, and nE are the same as previously (198 in this case).

With a t-value of 1.75 and a 92% confidence level (from a t-distribution with 198 degrees of freedom), we get:

CI is equal to (9.55 - 7.26) 1.75 * sqrt[(5.88 - + 6.94 / 100)] = (1.87, 2.63) (1.87, 2.63)

The genuine difference between night owls and early birds in terms of the average number of dreams recalled per week is therefore between 1.87 and 2.63, with a 92% confidence interval.

The standard deviation of the salaries for the company's 80 employees is calculated to be X, where X represents the numerical value of the standard deviation.

The standard deviation measures the dispersion or variability of a set of data points. In order to calculate the standard deviation, we need to first find the mean (average) of the salaries. Then, for each salary, we calculate the difference between the salary and the mean, square that difference, and sum up all the squared differences. Next, we divide the sum by the total number of salaries (80 in this case) minus 1 to obtain the variance. Finally, the standard deviation is obtained by taking the square root of the variance. This accounts for the fact that the squared differences are in squared units, while the standard deviation should be in the original units (currency in this case).

By following this process, we can find the standard deviation of the salaries for the 80 employees in the company. This value represents the measure of variability or spread in the salary distribution, providing insights into how salaries deviate from the mean.

(a) The probability of a team scoring seven goals in a match, assuming a Poisson distribution with mean 1.336, is approximately 0.072.

(b) The p-value, representing the probability of a team scoring seven or more goals, is approximately 0.138.

(c) According to the criterion of a p-value less than 0.05, we would not reject the proposal that the number of 2014 World Cup goals follows a Poisson distribution.

(d) The observed distribution suggests that a Poisson distribution is applicable for modeling the number of goals in the 2014 World Cup.

(a) To find the probability that a team scores seven goals in a match,

Use the Poisson distribution formula,

P(X = k) = \((e^{(-\lambda) \times \lambda^k)\) / k!,

where,

P(X = k) is the probability of scoring exactly k goals,

e is the base of the natural logarithm (approximately 2.71828),

λ is the mean number of goals per game per team.

Here, λ = 1.336 and k = 7.

P(X = 7) = (\(e^{(-1.336)\) × 1.336⁷) / 7!.

Calculating this value,

P(X = 7) ≈ 0.072.

The probability that a team scores seven goals in a match, according to the hypothesis, is approximately 0.072.

(b) The p-value in this case is the probability of a team scoring seven or more goals in a match.

Sum the probabilities of scoring seven, eight, nine, and so on, up to infinity (which is practically a very large number).

P(X ≥ 7) = P(X = 7) + P(X = 8) + P(X = 9) + ...

Since calculating an infinite sum is not feasible,

Approximate it by calculating the complementary probability of scoring less than seven goals and subtracting it from 1.

P(X ≥ 7) = 1 - P(X < 7).

To calculate P(X < 7),  sum the probabilities of scoring zero, one, two, three, four, five, and six goals.

P(X < 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6).

Calculating this value,

P(X < 7) ≈ 0.862.

The p-value, which is the probability of a team scoring seven or more goals in a match, is approximately 0.138 (1 - 0.862).

(c) According to the criterion of rejecting a hypothesis when the p-value is less than 0.05, we compare the p-value obtained (0.138) with 0.05.

Since 0.138 > 0.05,

Not reject the proposal that the number of 2014 World Cup goals is a Poisson-distributed random variable with a mean of 1.336.

(d) The observed probability distribution for the number of goals in the 2014 World Cup, quite similar to the Poisson distribution with a mean of 1.336.

This suggests that a Poisson distribution is applicable for modeling the number of goals scored per team per game.

However, further statistical analysis and hypothesis testing should be conducted

to confirm the validity of this assumption and explore other possible distributions.

The above question is incomplete, the complete question is:

The 2014 FIFA World Cup It has been suggested that the number of goals in World Cup games is given by a Poisson distribution. A total of 171 goals were scored at the 2014 World Cup in a total of 64 games, implying a mean number of goals per game per team of 1.336 Fig. 4.8 shows the observed probability distribution for the number of goals scored per team per game in the 2014 World Cup in blue, determined on the basis of goals per game per team actually scored, in comparison to a Poisson distribution in red corresponding to the actual mean number of goals per team per game (λ = 1.336) in the 2014 World Cup. Evidently, the observed distribution is quite similar to the Poisson distribution, which leads to the hypothesis that the number of goals that a team scored per game is a Poisson-distributed random variable with, in this case, λ 1.336 (a) But what about Germany's 7 goals in their semi-final game against Brazil? According to the hypothesis that the number of goals that a team scores per game is a Poisson-distributed random variable with mean λ = 1.336, what is the probability that a team scores seven goals in a match? (b) The p-value is the probability of achieving a result as extreme or more extreme than the result actually achieved. Therefore in this case the p-value is the probability of a team scoring seven or more goals in a match. What is the numerical value of the p-value in this case according to our hypothesis? (c) One criterion for rejecting a hypothesis is that the p-value is less that 0.05. According to this criterion, should we reject the proposal that the number of 2014 World Cup goals is a Poisson-distributed random variable with mean 1.336?

The probability that the project will take 224 days or longer is 0.1587.

This is a question on the normal probability distribution.

To expiate this, standardize the 95 days.

The standardized score is calculated by subtracting the value from the mean and dividing it by the standard deviation.

z = (x - xbar) ÷ σ

x = 224 days

xbar = mean = 214 days

σ = standard deviation = √(variance) = √100 = 10

z = (224 - 214) ÷ 10 = 1

To calculate the probability that the project will be finished in 95 days or less, P(x ≥ 224) = P(z ≥ (1))

For these probabilities, use data from the normal probability table.

P(x ≥ 224) = P(z ≥ (1)) = 1 - 0.8413 = 0.1587

The system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a.

To determine if the system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a, we can use the elimination method.

We want to eliminate one of the variables, so let's start by multiplying the first equation by 3 and the second equation by -1.

This gives us:

3Ax + 9y = 3a, -3x - ay = -A.

Now we add the equations together to get:

2Ax + 8y = 3a - A.

Now we can see that the equation is not solvable as there is no value of a that will make the equation true. Therefore, the system of linear equations Ax + 3y = a, 3x + ay = A has no solutions for any value of a.

The lifting force if the speed is 220 miles per hour is F' = 708.53 N.

The force of light, or simply light, is the sum of all forces on an object that cause the object to move perpendicular to the direction of flow.

The most common type of lift is the wing lift. But there are many other common uses, such as propellers on airplanes and ships, rotors on helicopters, fan blades, sails on sailboats, and wind turbines.

We have,

The lifting force, F, exerted on an airplane wing varies jointly as the area, A, of the wing's surface and the square of the plane's velocity, v. It, means that,

\(F=kAv^{2}\)

Where

k is constant

If, A = 190 Ft², v = 220 mph, F = 950 pounds

Now, find k first from the above data. So,

    \(k=\frac{F}{Av^{2} }\)

⇒ \(k=\frac{950}{190* (220)^2}\)

⇒ k = 0.0001033

It is required to find the lifting force on the wing if the plane slows down to 190 miles per hour.

Let F' is a new force. So,

    F' = 0.0001033 × 190 × (190)²

⇒ F' = 708.53 pounds.

So, the lifting force is 708.53 pounds if the plane slows down to 190 miles per hour.

The total interest you will earn in 30 years is approximately $241.61.

To calculate the total interest earned in 30 years, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt) - P
Where:
A = the future value of the investment
P = the principal amount (initial deposit)
r = the annual interest rate (in decimal form)
n = the number of times the interest is compounded per year
t = the number of years
In this case, the principal amount is $200, the annual interest rate is 3% (or 0.03 as a decimal), the interest is compounded monthly (so n = 12), and the time period is 30 years (so t = 30).
Plugging in these values into the formula:
A = 200(1 + 0.03/12)^(12*30) - 200
Now we can simplify and calculate:
A = 200(1.0025)^(360) - 200
A = 200(2.208040033) - 200

It is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given Data

(a) Probability that a car has a defect = 40% = 0.4.

Probability that a car with no defect = 1 - 0.4 = 0.6

Probability that 50 cars does not have defect = (0.6)50

Probability that 50 cars will have no defect and the 51st will = (0.6)50(0.4)

Probability that 50 cars will have no defect and the 51st will= 12

(b) This question can be understood in two ways. If the question is simply asking for the probability that the 20th car has a defect it is 40% or 0.4. If the question means 19 cars do not have a defect and the 20th has one, the answer is below -

Probability that 19 cars do not have defect = (0.6)19

Probability that 20th car will have defect = (0.6)19( 0.4)

Probability that 20th car will have defect   = 4.56                                                            

(c) The one car with defect can be chosen in 5 ways.

Probability that the car has a defect = 0.4

Probability that the remaining 4 cars do not have defect = (0.6)4

Probability that exactly one car has a defect = 5( 0.4) (0.6)4 = 0.2592.
