Z- Score give an idea how far a data point is from mean .

z = x- μ / σ where numerator is difference between the random variable and the actual mean dividing by the standard deviation .

Given , x = 47 inches

standard deviation = 2.5 inches

mean = 52 inches

z-score = x- μ / σ

putting all the values ,

z-score = 47 - 52 / 2.5

Answer:

No, she shouldn't.

Answer:

x^2 + 7/2 + 15 is the answer.

Step-by-step explanation:

Make the number that is equal to x be on the side of the x, then multiply those to values.

x = -6

x= 5/2

(x + 6)*(x - 5/2)

Now, distribute the x to the x and the negative 5/2, and add that to 6 distributed to x and negative 5/2. Simplify.

\(x^{2} + -\frac{5}{2}x + 6x + 15\\\\x^{2} + \frac{7}{2} + 15\)

Approximately, the age of the painting is 400.59 years using carbon-14 dating. However, this negative value indicates that the painting is not from the specified time period, suggesting an inconsistency or potential error in the data or analysis.

Based on the information provided, we can use the concept of carbon-14 dating to determine if the painting could have been created by the artist in question and estimate its age.

Carbon-14 is a radioactive isotope that undergoes radioactive decay over time with a half-life of 5730 years. By comparing the amount of carbon-14 remaining in a sample to its initial amount, we can estimate its age.

The fact that the painting contains 95.4 percent of its carbon-14 suggests that 4.6 percent of the carbon-14 has decayed. To determine the age of the painting, we can calculate the number of half-lives that would result in 4.6 percent decay.

Let's denote the number of half-lives as "n." Using the formula for exponential decay, we have:

0.954 = (1/2)^n

To solve for "n," we take the logarithm (base 2) of both sides:

log2(0.954) = n * log2(1/2)

n ≈ log2(0.954) / log2(1/2)

n ≈ 0.0703 / (-1)

n ≈ -0.0703

Since the number of half-lives cannot be negative, we can conclude that the painting could not have been created by the artist in question.

Additionally, we can estimate the age of the painting by multiplying the number of half-lives by the half-life of carbon-14:

Age of the painting ≈ n * half-life of carbon-14

≈ -0.0703 * 5730 years

≈ -400.59 years

(d.) Each run of the simulation only provides a sample of the actual system's operation.

This assertion is right, not mistaken. Indeed, each simulation run is a sample of the actual system's operation. A single simulation run cannot account for all possible outcomes and variations in the real system because simulations are based on mathematical models and involve random variations.

In order to take into consideration various scenarios and variations, multiple simulation runs are typically carried out. By running numerous reenactments, specialists can assemble a scope of results and measurable data to acquire a superior comprehension of the framework's way of behaving and go with informed choices.

The middle term in the expansion of (r + s)ⁿ depends on the value of n and whether it is odd or even.

The binomial theorem is described as an algebraic method for expanding any binomial of the form (a+b)ⁿ  without the need to expand all n brackets individually.

The coefficients of the third and thirteenth terms in the expansion of (r + s)ⁿ are given by the binomial coefficients C(n, 2) and C(n, 6), respectively.

Since  the two coefficients are equal, we can write:

C(n, 2) = C(n, 6)

If we solve for k:

k = n - (n - k) = n - (n - 2) = 2

So the middle term in the expansion is given by the coefficient C(n, (n - 1)/2) if n is odd.

But in the scenario n is even, we have  two middle terms with coefficient C(n, n/2) and C(n, n/2 - 1).

The tensions in each side of the rope will be the same when Nellie Newton hangs at rest in the middle of a clothesline and the lengths of each rope are the same.

When Nellie Newton is in equilibrium, meaning she is at rest and not experiencing any acceleration or movement, the forces acting on her must be balanced. In the case of a clothesline, the tension in each side of the rope contributes to the balancing of forces.

For the tensions to be the same in each side of the rope, the lengths of the ropes must also be the same. This ensures that the forces applied to each side are equal and balanced, resulting in Nellie Newton remaining in a stable position without any net force acting on her.

V ≈ 68.63 cm³

Step-by-step explanation:

the volume (V) of a sphere is calculated as

V = \(\frac{4}{3}\)πr³

the volume of a hemisphere is half the volume of a sphere, so

V = \(\frac{1}{2}\) × \(\frac{4}{3}\) πr³ = \(\frac{2}{3}\) πr³ , then

V = \(\frac{2}{3}\) π × 3.2³

The proportion of all U.S. adolescents ages 10-14 who started smoking because of seeing actors smoke in movies by constructing a 95% confidence interval is (0.368, 0.392). So, the correct option is A).

Proportion of all U.S. adolescents aged 10-14 who started smoking due to seeing actors smoke in movies by constructing a 95% confidence interval.

The sample size of the study is 6,522, and of those who subsequently tried smoking for the first time, 38% did so because of exposure to smoking in the movies.

To construct a confidence interval, we need to use the sample proportion of 0.38 and calculate the standard error of the proportion:

SE = sqrt[(p*(1-p))/n]

SE = sqrt[(0.38*(1-0.38))/6522]

SE = 0.007

Next, we can use a z-score of 1.96 for a 95% confidence interval and plug in the values:

CI = p +/- zSE

CI = 0.38 +/- 1.960.007

CI = (0.366, 0.394)

Therefore, the 95% confidence interval for the proportion of all U.S. adolescents aged 10-14 who started smoking is (0.366, 0.394). So, the correct answer is A).

Answer:

Note:  The expression "h =300- pi r /pi r" would equate to 299, as written.  I find h = (300 - π\(r^{2}\) )/πr to be the equation for height.

Step-by-step explanation:

The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius.  That consists of top and bottom disks, each with an area of π\(r^{2}\), for a total of 2π\(r^{2}\).  The side is a  continous sheet that has an area of 2πrh, where h is the height.  2πr is the circumference of the can, so the surface area of the side is 2πrh.

The total surace area of a closed cylinder is therefore 2π\(r^{2}\) + 2πrh.

2π\(r^{2}\) + 2πrh = 600

π\(r^{2}\) + πrh = 300

πrh = 300 - π\(r^{2}\)

h = (300 - π\(r^{2}\) )/πr

What is Compound Interest ?

Compound interest refers to the process of earning interest on both the initial principal amount as well as any accumulated interest from previous periods. In other words, it is the interest that is earned on the interest that has been accumulated over time.

We can use the formula for compound interest to solve this problem.

Where:

A = the final amount

P = the initial amount

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this problem, we have:

P = $250

r = 0.06% = 0.0006 (as a decimal)

n = 12 (since the interest is compounded monthly)

A = 3P = $750

Substituting these values into the formula, we get:

750 = 250\((1 + 0.0006/12) ^{12t}\)

Dividing both sides by 250, we get:

3 =\((1 + 0.0006/12) ^{12t}\)

Taking the natural logarithm of both sides, we get:

㏒(3) = 12t ㏒(1 + 0.0006÷12)

Solving for t, we get:

t = ㏒(3)/(12 ㏒(1 + 0.0006÷12))

Plugging this into a calculator, we get:

t ≈ 387.3 months

Therefore, it will take about 387.3 months (or about 32.3 years) to triple the balance of the account.
