(L5) A(n) _____ is an argument that begins with the assumption that a conclusion is false, then uses logical reasoning to show that the assumption leads to a contradiction.

Answer:

I think the answer is 21 students

Step-by-step explanation:

I think it's 21 students because it said twice as much girls which is telling us to multiply 7 by 2 or 7 plus 2 and in this case the product/sum would be 14, and now we add 7 boys by 14 girls and that will be 21 students altogether.

At the end of the day on the daughter's 24th birthday, there will be approximately $24,764 in the account.

To calculate the amount in the account at the end of the day on the daughter's 24th birthday, we need to consider the yearly deposits and the compounded interest.

The initial deposit was $1000. Then, for the next 23 years (from the daughter's 1st birthday to her 23rd birthday), the father made additional deposits of $1000 each year. This gives us a total of 23 * $1000 = $23,000 in deposits.

Now, let's calculate the amount of interest earned. The interest rate is 5.25%, compounded annually. Since the interest is compounded annually, the total number of compounding periods is also 23 (from the daughter's 1st birthday to her 23rd birthday).

To calculate the interest earned, we use the formula:

Interest = Principal * (1 + Interest Rate)^Number of Periods - Principal

Principal = $1000

Interest Rate = 5.25% or 0.0525

Number of Periods = 23

Interest = $1000 * (1 + 0.0525)^23 - $1000

Now, let's calculate the values:

Interest = $1000 * (1.0525)^23 - $1000

Interest ≈ $1000 * 1.764 - $1000

Interest ≈ $764

Therefore, the interest earned is approximately $764.

To find the total amount in the account at the end of the day on the daughter's 24th birthday, we add the deposits and the interest earned:

Total amount = Initial deposit + Deposits + Interest earned

Total amount = $1000 + $23,000 + $764

Total amount ≈ $24,764

Yes, the sample size would be large enough if the population is school-aged children and young adults in the United States as this is a simple random sampling.

Simple random sampling is used for randomly selecting the sample size for research. No member in the population has a higher chance in comparison to others for selection in sampling. Every individual has an equal chance to be a part of the sample for the study. This is a type of probability sampling method.

The probability sampling method states that every individual has a fair and equal chance to be selected as a research sample. It includes simple random sampling, stratified sampling, systematic sampling, and cluster sampling. Here the researchers have picked around 150 students and young adults which is an appropriate amount of simple random sample for the study.

False. The hour property of the datetime structure stores the hour as an integer between 0 and 23.

To support varied needs, three different property types are available:

1. Date — A day of the Gregorian calendar, without reference to a time zone or locale. The unit is a whole day, such as July 23, 2006.

2. Time of Day — A time of day, without reference to a time zone or locale. The unit is seconds, such as 15 seconds after 1:25 P.M.

3. Date Time — A date and time, stored internally to the millisecond if available, in a known time zone. For example 15.452 seconds after midnight on July 23, 2006 in London, U. K.

When presented with a DateTime value, a corresponding date and a time-of-day (in a specified time zone) can be determined.

However, the converse is not usually true: when starting with a Date and a TimeofDay value, multiple differing but "correct" DateTime values can be constructed, depending on assumptions about time zone, Daylight Savings Time, and other considerations. For example, when the date is January 1 in London, it can be December 31 in New York.

Thus, the given statement is false.

Answer:25

Step-by-step explanation:

If the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

The given parameters are

The binomial (x−7) is a factor of the polynomial function f(x)

The above means that

When the function f(x) is divided by x - 7, it has no remainder

So, we have

x - 7

Set to 0

x - 7 = 0

Add 7 to both sides

x = 7

Substitute x = 7 in f(x) = 0

f(7) = 0

Hence, if the binomial (x−7) is a factor of the polynomial function f(x), then the true statement is f(7) = 0

a = y2 / (b^x2) ,To find the initial value of an exponential function, you can use the formula y = a * b^x, where y represents the final value, a represents the initial value, b represents the base, and x represents the exponent.

To solve for the initial value (a), you need to have at least two points on the exponential function. Let's say you have the point (x1, y1) and (x2, y2).

Step 1: Substitute the values of x1, y1, x2, and y2 into the formula y = a * b^x.

Step 2: Since the goal is to find the initial value (a), we can set up two equations using the given points.

For the first point (x1, y1):
y1 = a * b^x1

For the second point (x2, y2):
y2 = a * b^x2

Step 3: Divide the second equation by the first equation to eliminate the base (b):

y2/y1 = (a * b^x2) / (a * b^x1)

Step 4: Simplify the equation:

y2/y1 = b^(x2 - x1)

Step 5: Take the logarithm of both sides of the equation to isolate the exponent (x2 - x1):

log(y2/y1) = (x2 - x1) * log(b)

Step 6: Solve for (x2 - x1):

(x2 - x1) = log(y2/y1) / log(b)

Step 7: Substitute the value of (x2 - x1) into either of the original equations to solve for a:

a = y1 / (b^x1)

or

a = y2 / (b^x2)

Remember to use the same base (b) in all calculations. This will help you find the initial value (a) of the exponential function.

The statement is False. The residuals will not necessarily add up to 0.

The residuals from a linear regression analysis are the differences between the observed values of the dependent variable and the predicted values of the dependent variable. Therefore, the sum of the residuals will depend on the data and the model used. If the model is a perfect fit, then the sum of the residuals will be 0. However, in most cases, the model will not be a perfect fit and the sum of the residuals will not be 0.

The probability that X is equal to 3.94 is approximately 0.0286.

Since X follows a chi-square distribution with 10 degrees of freedom, its probability density function (pdf) is given by:

\(f(x) = (1/2^(10/2) * Gamma(10/2)) * x^(10/2 - 1) * e^(-x/2)\)

where Gamma() is the gamma function.

To find the probability that X is equal to 3.94, we need to evaluate the pdf at that value, i.e., we need to find f(3.94). Plugging in the values, we get:

\(f(3.94) = (1/2^(10/2) * Gamma(10/2)) * (3.94)^(10/2 - 1) * e^(-3.94/2)\)≈ 0.0286

So the probability that X is equal to 3.94 is approximately 0.0286. Note that since X is a continuous random variable, the probability of it taking any particular value is zero. However, we can still talk about the probability of X being within a certain range or interval.

The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.

The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.

Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.

Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

The expression for the power delivered to a resistance in terms of csc^2 2 pi ft is P = I^2_0 R (csc^2 2 pi ft).

According to the given information, the power delivered to a resistance R when an alternating current of frequency f and peak current I_0 passes through it is represented by the equation P = I^2_0 R sin^2 2 pi ft.

To express this equation in terms of csc^2 2 pi ft, we can use the trigonometric identity csc^2 x = 1/sin^2 x. Substituting this identity into the equation, we get P = I^2_0 R (1/sin^2 2 pi ft).

The father is 40 years old, and his daughter is 10 years old.

Step-by-step explanation:

Given that a father is four times the age of his daughter, and after 5 years, he would be 3 times of daughter's age, then further after 5 years, to determine how many times he would be of his daughter's age, the following calculation must be done:

F = 4D

F + 5 = 3D

F = 40

D = 10

40 + 5 = 3 x (10 + 5)

45 = 45

Therefore, the father is 40 years old, and his daughter is 10 years old.
