The approximation using the binomial series for f'(1/2) is 3/8, while the calculator result for f'(1/2) is approximately 1.414. The approximation is not close to the calculator result.

To approximate the function \(f(x) = (1 + x)^{(1/2)\)  using the binomial series, we can expand it as follows:

\(f(x) = (1 + x)^{(1/2) }= 1 + (1/2)x - (1/8)x^2\)

To find f'(1/2), we can differentiate the above expression:

f'(x) = (1/2) - (1/4)x

Evaluating f'(1/2):

f'(1/2) = (1/2) - (1/4)(1/2)

        = (1/2) - (1/8)

        = 4/8 - 1/8

        = 3/8

Now let's calculate f'(1/2) = 1/(1-x)^(1/2) using a calculator:

\(f'(1/2) = 1/(1 - 1/2)^{(1/2)} = 1/(1/2)^{(1/2)\)

       = 1/(√(1/2))

       ≈ 1.414

Comparing the approximation from the binomial series to the calculator result, we have:

Approximation from the binomial series: 3/8 ≈ 0.375

Calculator result: 1.414

The approximation from the binomial series is not close to the calculator result. The two values differ significantly.

Step-by-step explanation:

If you are rounding to the whole number you are rounding to ones so you need to look at the tenth digit:

2<5 so 7 stays the same  (rounding down)

7.21 ≈ 7

The nearest whole number for the given number is 7.

To change a number into an approximation having fewer significant digits. For example :-

Round off 15.4 to 15, round off 15.51 to 15.5 or to 16, round off 0.499 to 0, and round off 970,000 to 1 million.

Given is a number 7.21,

We know that,  if the digit is less than 5, round down and if the digit is 5 or more than 5, round up.

Since, numbers after the decimal is not greater than 5, therefore, it will not change and will remain 7.

Hence, the required whole number is 7.

Answer:

6 yards long

Step-by-step explanation:

1/3 yards wide = 2 yards long

Let x = length of the other rug

1 yard wide = x yards long

1/3 : 2 = 1 : x

1/3 ÷ 2 = 1 ÷ x

1/3 × 1/2 = 1 / x

1/6 = 1/ x

Cross product

1*x = 6*1

x= 6 yards

Therefore, the length of the new rug with 1 yard wide is 6 yards long

The first thing to do is to find the ratio of wide to long of the two rugs by representing the long of the second rug with x

There are 15 different positive divisors (greater than 1) for the number m³pt. Here m, p, and t are distinct prime numbers. This is obtained by the prime factorization method.

The following are the steps to find the number of positive factors of a number:

Step 1: Find the L.C.M of the number by using the prime factorization method. For example: consider the number 24. Then, its prime factorization is as follows:

24 = 2 × 2 × 2 × 3

Step 2: Same bases should be added in powers. So, the factors we can write as

24 = 2³ × 3¹

Step 3: To find the number of positive factors of the number, the exponents of the prime factors is multiplied by adding 1.

I,e., N = (3 + 1)(1 + 1) = 4 × 2 = 8.

So, there are 8 factors for the number 32. They are 1, 2, 3, 4, 6, 8, 12, and 24.

It is given that, m, p, and t are distinct positive prime numbers.

Then, the number of positive divisors greater than 1 for the number m³pt are

m³× p × t

Since m, p, and t are prime factors, we can multiply their power by adding 1 to them. I.e.,

N = (3 + 1) (1 + 1) (1 + 1) = 4 × 2 × 2 = 16

So, there are a total of 16 factors for the given number (including 1). So, the number of factors greater than 1 is 16 - 1 = 15.

Therefore, there are 15 different positive divisors greater than 1 for the number having prime factors as m³pt.

The minimal score for admission is 628 and the mean blood pressure of patients is 155.

b) The minimal score for admission is the score which is located in the top 10% of the distribution. The score will be located at the 90th percentile. Since the scores are normally distributed, we can use the z-score to calculate the corresponding score at the 90th percentile.

The z-score at the 90th percentile is 1.28. Therefore, the minimal score for admission would be 500+1.28×100 = 628.

c) Since only 8% of patients exceed 140, the mean blood pressure of patients will be located at the 92nd percentile. Therefore, we can use the z-score to calculate the corresponding score at the 92nd percentile.

The z-score at the 92nd percentile is 1.5. Therefore, the mean blood pressure of patients would be 140+1.5×10 = 155.

Therefore, the minimal score for admission is 628 and the mean blood pressure of patients is 155.

The approximate probability that the total score is at least 375 when a fair six-sided die is rolled 100 times is (d) 0.4420.

When a fair six-sided die is rolled, the random variable X represents the outcome. The mean (μX) of X is 3.5, and the standard deviation (σX) is 1.71.

To find the probability that the total score is at least 375 when the die is rolled 100 times, we can use the Central Limit Theorem. According to the theorem, the sum of a large number of independent and identically distributed random variables approximates a normal distribution.

In this case, the sum of the outcomes of 100 rolls of the die follows a normal distribution with a mean of μX multiplied by the number of rolls (100) and a standard deviation of σX multiplied by the square root of the number of rolls (10). Therefore, the approximate probability can be calculated by finding the probability that the sum is greater than or equal to 375.

Using a normal distribution table or a calculator, we can find that the approximate probability is 0.4420, which corresponds to answer (d). This means that there is a 44.20% chance that the total score will be at least 375 when the die is rolled 100 times.

Answer:

A positive z-score indicates that a particular value is greater than the mean, a negative z-score indicates that a particular value is less than the mean, and a z-score of zero indicates that a particular value is equal to the mean.

Step-by-step explanation:

Examples: Calculating a Z-Score

Suppose we have the following dataset that shows the height (in inches) of a certain group of plants:

5, 7, 7, 8, 9, 10, 13, 17, 17, 18, 19, 19, 20

The sample mean of this dataset is 13 and the sample standard deviation is 5.51.

1. Find the z-score for the value “8” in this dataset.

Here is how to calculate the z-score:

z  =  (X – μ) / σ  =  (8 – 13) / 5.51  =  -0.91

This means that the value “8” is 0.91 standard deviations below the mean.

2. Find the z-score for the value “13” in this dataset.

Here is how to calculate the z-score:

z  =  (X – μ) / σ  =  (13 – 13) / 5.46  =  0

This means that the value “13” is exactly equal to the mean.

3. Find the z-score for the value “20” in this dataset.

Here is how to calculate the z-score:

z  =  (X – μ) / σ  =  (20 – 13) / 5.46  =  1.28

The negative z-score indicates that a particular value will be less than the mean.

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

The points regarding the z-score are as follows:

The negative z-score indicates that a particular value will be less than the mean.

The correct answer is c. Inferential Statistics.

Inferential statistics is the branch of statistics that allows for drawing conclusions about a population based on the information collected from a sample. When conducting research or surveys, it is often impractical or impossible to collect data from an entire population.

Instead, a representative sample is chosen, and inferential statistics are used to make inferences or predictions about the larger population. By analyzing the characteristics and patterns observed within the sample, inferential statistics enable researchers to make generalizations or draw conclusions about the population as a whole.

This process involves applying various statistical techniques, such as hypothesis testing and confidence intervals, to estimate population parameters and assess the reliability of the conclusions. Magnitude statistics, central tendency, and effect size are important concepts in statistics, but they do not specifically address the ability to draw population-level conclusions from sample data.

Magnitude statistics focuses on the size of the effect or relationship between variables, central tendency measures summarize the central values of a dataset, and effect size quantifies the strength of an effect or relationship.
