Answer:

It is difficult to pinpoint a specific year or time period in which math was "invented," as math is a fundamental aspect of human thought and has likely been present in some form since ancient times.

The study of mathematics has a long and rich history, dating back to ancient civilizations in Mesopotamia, Egypt, Greece, and India. These early societies developed mathematical concepts and techniques to aid in practical tasks such as measuring land, calculating the volume of objects, and tracking the movement of celestial bodies.

As human civilizations developed and advanced, so too did the study of mathematics. Over time, new mathematical concepts and techniques were developed and refined, leading to the development of more advanced branches of mathematics such as algebra, geometry, trigonometry, and calculus.

In summary, math has a long and complex history, and it is difficult to pinpoint a specific year or time period in which it was "invented." It has likely been present in some form since ancient times and has evolved and developed over the course of human history.

The approximate probability that a randomly selected US adult woman is shorter than 69.5 inches is 0.9772 or about 97.72%.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence.

We are given that the height of adult women in the US follows a normal distribution with a mean of 64.5 inches and a standard deviation of 2.5 inches.

We need to find the probability that a randomly selected US adult woman is shorter than 69.5 inches.

To find this probability, we need to calculate the z-score first:

z = (x - mu) / sigma

where x is the height we want to find the probability for, mu is the mean, and sigma is the standard deviation.

Substituting the values, we get:

z = (69.5 - 64.5) / 2.5 = 2

Using a standard normal distribution table or calculator, we find that the probability of a z-score of 2 or less is 0.9772.

Therefore, the approximate probability that a randomly selected US adult woman is shorter than 69.5 inches is 0.9772 or about 97.72%.

The value of the double integral using the easier order, ydA bounded by y = x − 6; x = y² is 125/12.

The double integral, indicated by ', is mostly used to calculate the surface area of a two-dimensional figure. By using double integration, we may quickly determine the area of a rectangular region. If we understand simple integration, we can easily tackle double integration difficulties. Hence, first and foremost, we will go over some fundamental integration guidelines.

Given, the double integral ∫∫yA and the region y = x-6 and x = y²

y = x-6

x = y²

y² = y +6

y² - y - 6 = 0

y² - 3y +2y - 6 = 0

(y-3) (y+2) = 0

y = 3 and y = -2

\(\int\int\limits_\triangle {y} \, dA\\ \\\)

= \(\int\limits^3_2 {y(y+6-y^2)} \, dx \\\\\int\limits^3_2 {(y^2+6y-y^3)} \, dx \\\\(\frac{y^3}{3} + 3y^2-\frac{y^4}{4} )_-_2^3\\\\\frac{63}{4} -\frac{16}{3} \\\\\frac{125}{12}\)

The value for the double integral is 125/12.

Integration is an important aspect of calculus, and there are many different forms of integrations, such as basic integration, double integration, and triple integration. We often utilise integral calculus to determine the area and volume on a very big scale that simple formulae or calculations cannot.

a. The probability that at most 6 people in a sample of 10 have Internet access can be found using the binomial probability formula.

Given that 80% of the people in the community have Internet access, the probability of an individual having access is 0.8. We can then calculate the probability of having 0, 1, 2, 3, 4, 5, or 6 people with Internet access and sum up these probabilities.

b. The probability that exactly 6 people in a sample of 10 have Internet access can also be calculated using the binomial probability formula. We need to find the probability of having exactly 6 people with Internet access and no more or no fewer.

c. The probability that not more than 6 people in a sample of 10 have Internet access can be calculated by summing up the probabilities of having 0, 1, 2, 3, 4, 5, or 6 people with Internet access. This includes cases where fewer than 6 people have Internet access.

d. The event with the highest probability of occurring among a, b, and c is event c, where not more than 6 people have Internet access.

This is because event c encompasses both event an (at most 6 people have Internet access) and event b (exactly 6 people have Internet access).

Since the probability of not more than 6 people having Internet access includes all the cases in the event a and event b, it is more likely to occur than either of the individual events.

The  total number of ways to arrange 3 copies of introduction to geometry and 4 copies of introduction to number theory on a bookshelf is 35.

A permutation of a set of objects is an ordering of those objects. When some of those objects are identical, the situation is transformed into a problem about permutations with repetition. Problems of this form are quite common in practice; for instance, it may be desirable to find orderings of boys and girls, students of different grades, or cars of certain colors, without a need to distinguish between students of the same grade (or cars of the same color, or people of the same gender).

Total number of copies = 3 +4 = 7

Number of ways to arrange 7 copies together = 7!

However, there are 3 copies of introduction to geometry and 4 copies of introduction to number theory. Thus, all copies of each book are identical.

Now, the total number of ways to arrange 7 copies together

= \(\frac{7!}{3!* 4!}\)

Density of tulips for the area is ≈ 14.6 tulips per square meter

The area of the square flower bed is given by the formula:

A = \(s^2\)

where s is the length of a side of the square. Substituting s = 5 meters, we get:

A = \(5^2\) = 25 square meters

The density of tulips is defined as the number of tulips per unit area. Therefore, the density of tulips in the flower bed is:

density = number of tulips / area

Substituting the given values, we get:

density = 365 / 25 ≈ 14.6 tulips per square meter

Rounding to the nearest tenth, we get:

density ≈ 14.6 tulips per square meter (rounded to one decimal place)

Isabella would have $2970.63 in the account 14 years after her initial investment.

Isabella invested $1300 in an account that pays 4.5% interest compounded annually.

Assuming no deposits or withdrawals are made, find how much money Isabella would have in the account 14 years after her initial investment. Round to the nearest tenth (if necessary).

The formula for calculating the compound interest is given by

A=P(1+r/n)^(nt)

where A is the final amount,P is the initial principal balance,r is the interest rate,n is the number of times the interest is compounded per year,t is the time in years.

Since the interest is compounded annually, n = 1

Let's substitute the given values in the formula.

A = 1300(1 + 0.045/1)^(1 × 14)A = 1300(1.045)^14A = 1300 × 2.2851A = 2970.63

The area of the shaded sector is 4π square units.

To find the area of the shaded sector, we need to calculate the central angle formed by the sector. In this case, we are given that the angle JIK is 90 degrees, which means it forms a quarter of a full circle.

Since a full circle has 360 degrees, the central angle of the shaded sector is 90 degrees.

Next, we need to determine the radius of the circle. The line segment IJ represents the radius of the circle, and it is given as 4 units.

The formula to calculate the area of a sector is A = (θ/360) * π * r², where θ is the central angle and r is the radius of the circle.

Plugging in the values, we have A = (90/360) * π * 4².

Simplifying, A = (1/4) * π * 16.

Further simplifying, A = (1/4) * π * 16.

Canceling out the common factors, A = π * 4.

Hence, the area of the shaded sector is 4π square units.

Therefore, the area of the shaded sector, expressed as a fraction times π, is 4π/1.

In summary, the area of the shaded sector is 4π square units, or 4π/1 when expressed as a fraction times π.
