Based on the weight of the individual and the percentage of body fat, the amount of pounds that is made up of fat is 24.9 pounds

When given the percentage of something like the body fat of an individual and you need to find the actual pounds of the person's weight that is body fat, you should multiply the percentage by the total weight of the person.

This means that to find the pounds of the individual's weight that is made up of fat you can use the formula:
= Percentage body fat x Weight of individual

Solving gives:

= 18.3% x 136 pounds

= 0.183 x 136

= 24.888

= 24.9 pounds

The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.

To find the values of Z, we can start by expressing 2 + i√3 in polar form. Let's denote it as re^(iθ), where r is the modulus and θ is the argument.

Given: 2 + i√3

To find r, we can use the modulus formula:

r = sqrt(a^2 + b^2)

= sqrt(2^2 + (√3)^2)

= sqrt(4 + 3)

= sqrt(7)

To find θ, we can use the argument formula:

θ = arctan(b/a)

= arctan(√3/2)

= π/3

So, we can express 2 + i√3 as sqrt(7)e^(iπ/3).

Now, we can find the values of Z by taking the natural logarithm (ln) of sqrt(7)e^(iπ/3) and adding 2πik, where k is an integer. This is due to the periodicity of the logarithmic function.

ln(sqrt(7)e^(iπ/3)) = ln(sqrt(7)) + i(π/3) + 2πik

Therefore, the values of Z are:

Z = ln(2 + i√3) + 2πik, where k is an integer.

The values of Z such that e² = 2 + i√3 are Z = ln(2 + i√3) + 2πik, where k is an integer.

Step-by-step explanation:

Note that the two leg sides are both 20 measurements, suggesting that it is an isosceles triangle.

By definition of a isosceles triangle, the angles will be 45-45-90, and the sides will follow the 1-1-√2 rule, in which the 1 stands for the legs, and the √2 stands for the hypotenuse.

Note that the leg side measures 20. Multiply:

The method that was used to arrive at the approximate population probability is called; a reasonable statistical generalization

Statistical generalization is a concept that involves inferring the results from a sample and applying it to a population. Carrying out this means that the sample must be selected randomly and be representative of the population.

Now, in this case, we see that the sample gave a probability of 68% to represent those were in favor of legalizing recreational marijuana use.

Now, since the conclusion was approximated to 70% to reflect the probability of the population then we can say that a reasonable statistical generalization was utilized.

Step-by-step explanation:

Using the rule of radicals

\(\sqrt{a}\) × \(\sqrt{b}\) ⇔ \(\sqrt{ab}\)

Given

(3 + \(\sqrt{3}\) )(2 + \(\sqrt{2}\) )

Each term in the second factor is multiplied by each term in the first factor, that is

3(2 + \(\sqrt{2}\) ) + \(\sqrt{3}\) (2 + \(\sqrt{2}\) ) ← distribute both parenthesis

= 6 + 3\(\sqrt{2}\) + 2\(\sqrt{3}\) + \(\sqrt{6}\)

We have that a and c are in S, but [a,c] is not a subset of S, which contradicts the given property. Therefore, S must contain all the points between a and b, and is therefore an interval.

To show that x, y exist in S, we can use proof by contradiction. Suppose that x, y do not exist in S. This would mean that either x or y is not in S, which contradicts the fact that S contains at least two points. Therefore, x and y must both be in S.

Now, to show that S is an interval, we need to show that it contains all the points between any two points in S. Let a and b be two points in S, with a < b. By the property given in the question, we know that [a,b] is a subset of S.

To show that S contains all the points between a and b, suppose there exists some c between a and b that is not in S. Without loss of generality, assume that a < c < b. Then, we have that a and c are in S, but [a,c] is not a subset of S, which contradicts the given property. Therefore, S must contain all the points between a and b, and is therefore an interval.

The percentage of the tip that Serena's father paid was 20%.

Mathematically, a percentage is a numerical ratio, usually expressed as a fraction of 100 and denoted by the percent sign (%).

Percentages show the proportional relationship between two fractions, like proportions and ratios.

The amount of the tip = $5

The cost of the ride = $25

The total amount paid by Serena's father = $30 ($5 + $25)

The percentage of tip to the ride's cost = The amount of the tip divided by the cost of the ride.

= 20% ($5/$25 x 100)

Thus, in percentage terms, the amount that Serena's father tipped the taxi driver is 20% of the ride's actual cost.

The total cost of skateboard after tax is removed = $87.53

Initial cost of scateboard = $79.57

Discount = 12%

Discounted price = Initial cost of scateboard × 12%

= 79.57 × 0.12

Discounted price = 9.5484 = $9.55

Note: Discount is subtracted while sales tax is added to the cost of item

The amount left after discount is removed before tax= Initial cost of scateboard - Discounted price

The amount left after discount is removed = $79.57 - $9.55

The amount left after discount is removed = $70.02

Sales tax = 25%

Amount of sales tax = The amount left after discount is removed × 25%

= $70.02 × 0.25 = 17.505

Amount of sales tax = $17.51

The total cost of skateboard after tax is removed = The amount left after discount is removed + Amount of sales tax

The total cost of skateboard after tax is removed = $70.02 + $17.51

The total cost of skateboard after tax is removed = $87.53

Option A is correct, the required simplified value of the x is given as 35.

In triangle DEF, if m∠D = (2x)°, m∠E = (2x − 4)°, and m∠F = (x + 9)°.

for the triangle sum of the interior angles is equal to 180°.

∠D + ∠E + ∠F = 180

2x + 2x - 4 + x + 9 = 180

5x + 5 = 180

5x = 175

x = 35

Thus, the required simplified value of the x is given as 35.

The sum of the measures of the interior angles of a triangle in Euclidean space is continually 180 stages. This reality is equal to Euclid's parallel postulate. This permits the determination of the degree of the 1/3 perspective of any triangle, given the measure of angles. An exterior perspective of a triangle is an attitude that is a linear pair (and subsequently supplementary) to an indoor angle.  

The degree of an exterior perspective of a triangle is the same as the sum of the measures of the 2 indoor angles that aren't adjoining to it; this is the outside perspective theorem. The sum of the measures of the 3 exterior angles (one for every vertex) of any triangle is 360 degrees.

If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean. In repeated sampling, about 90% of the constructed confidence intervals will capture the true population mean difference. The correct answer is C.

When we construct a confidence interval, it is important to understand its interpretation. In this case, the correct answer (Oc) states that if we were to take many random samples of the same size and construct confidence intervals for each sample, approximately 90% of these intervals would contain the true population mean difference.

This interpretation is based on the concept of sampling variability. Due to random sampling, different samples from the same population will yield slightly different sample means.

The confidence interval accounts for this variability by providing a range of values within which we can reasonably expect the true population mean difference to fall a certain percentage of the time.

In the given scenario, when constructing a 90% confidence interval for the paired difference, it means that 90% of the intervals we construct from repeated samples will successfully capture the true population mean difference, while 10% of the intervals may not contain the true value.

It's important to note that this interpretation does not imply a probability or chance for an individual interval to capture the true population mean. Once the interval is constructed, it either does or does not contain the true value. The confidence level refers to the long-term behavior of the intervals when repeated sampling is considered.
