The minimum value of 8x³ + 54x + 27³x + 36x  is  81√6/7.

The minimum value of 8x³ + 36x + 54x + 27³x  for positive real numbers x is 81√6.

We have the expression: 8x³ + 36x + 54x + 27³x

Let's factorize it in the following way : 8x³ + 54x + 27³x + 36x = 8x³ + 3³x(3²x + 2) + 3²(3x²) = 8x³ + 3³x(3²x + 2) + 9(3x²)

Let's consider the AM-GM inequality : a + b ≥ 2√ab, for any real positive numbers a and b.

So, we have :

8x³ + 3³x(3²x + 2) + 9(3x²) = 8x³ + 9(3x²) + 3³x(3²x + 2)≥ 3√[8x³ × 9(3x²) × 3³x(3²x + 2)]

This implies : 8x³ + 9(3x²) + 3³x(3²x + 2) ≥ 18x√[2x]

This is because 8x³ × 9(3x²) × 3³x(3²x + 2)

= 81(2x)³x²(3²x + 2)

= 1458(2x)³x³(3²x + 2)

Thus, 8x³ + 9(3x²) + 3³x(3²x + 2) ≥ 18x√[2x]

The minimum value of 18x√[2x] is when 2x is equal to 1.

This is because when 2x is equal to 1,

we have: 18x√[2x] = 18(1/2)√1 = 9.

Now, 8x³ + 9(3x²) + 3³x(3²x + 2) ≥ 9.

In other words,8x³ + 54x + 27³x + 36x ≥ 9

This implies: 8x³ + 54x + 27³x + 36x + 81³x ≥ 9 + 81³x = 81(1 + 3³x)

The above inequality can be written as: (1 + 3³x)(8x³ + 54x + 27³x + 36x) ≥ 81

Therefore, 8x³ + 54x + 27³x + 36x ≥ 81/(1 + 3³x)

This implies: 8x³ + 54x + 27³x + 36x ≥ 81/28

The above inequality can be written as: 8x³ + 54x + 27³x + 36x ≥ 81√6/14

This implies: 8x³ + 54x + 27³x + 36x ≥ 81√6/7.

Table (2) is a probability distribution table.

Probability is the possibility of happening an event.

Note the probability can never be negative, therefore, discard the tables with negative values.

Hence, table (1) and table (3) cannot be probability distribution tables.

Now, the sum of all probabilities in a probability distribution is always 1.

The sum of probabilities in the table (2) is:

0.6 + 0.05 + 0.05 +0.3

=1.0

And, the sum of probabilities in the table(4) is:

0.4 + 0.4 + 0.2 + 0.1

=1.1

The equilibrium price of widgets in this market is $65 per unit, and the equilibrium quantity is 407 units.

The market demand for widgets is given by the equation Q = 1297 - 14p, where p is the price of widgets and Q is the quantity demanded. The market supply of widgets is given by the equation Q = -3 + 6p, where Q is the quantity supplied.

To find the equilibrium price and quantity, we need to set the quantity demanded equal to the quantity supplied:

1297 - 14p = -3 + 6p

Solving for p, we get:

20p = 1300

p = 65

So the equilibrium price of widgets is $65 per unit. To find the equilibrium quantity, we substitute this price into either the demand or supply equation:

Q = 1297 - 14(65) = 407

Therefore, the equilibrium quantity of widgets is 407 units.

Answer:

51°

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180°.

x + 60 + x + 82 + 56 = 180

2x + 198 = 180

2x = -18

x = -9

Answer: 51°

The ball traveled approximately 127.28 feet from home plate to second base.

In baseball, the paths between bases form a square with side lengths of 90 feet each. When the catcher throws the ball from home plate to second base, the ball travels along the diagonal of this square.

To find the length of the diagonal, you can use the Pythagorean theorem, which states that the square of the length of the hypotenuse (the diagonal) is equal to the sum of the squares of the other two side lengths.

In this case, both side lengths are 90 feet, so the equation is:

Diagonal² = 90² + 90²

Diagonal² = 8,100 + 8,100

Diagonal² = 16,200

To find the length of the diagonal, take the square root of 16,200:

Diagonal ≈ 127.28 feet

The area of the dilated figure is approximately 56250.0 mm².

Let's assume that the composite figure is composed of two shapes, Shape A and Shape B. The area of the composite figure is given as 289.7 mm².

Total Area = Area of Shape A + Area of Shape B

Total Area = 100 mm² + 150 mm²

Total Area = 250 mm².

If we dilate this figure by a scale factor of 3, the area of the new figure will be:

New Area = Scale Factor² x Total Area

                 = 3² x 250 mm²

                 = 225 x 250 mm²

                 = 56250 mm²

Answer:

Step-by-step explanation:

Triangle inequality says that the third side can only be 18-3...15, that is bigger than 15.

And 18+3... 21, that is smaller than 21.

If the third side is 21, the 18 and the 3 will just lay right on top of the 21 and not make a triangle. So it has to be 20 in order to be a whole number.

Answer: Number of water bottles a team can fill  from a single watercooler = 48

Step-by-step explanation:

Given: A watercooler contains 160 cups of water.

Each person on a team fills a water bottle with \(3\dfrac13\) cups of water from the cooler.

Here, \(3\dfrac13=\dfrac{10}{3}\)

Now , Number of water bottles a team can fill  from a single watercooler = \(160\div \dfrac {10}3\)

\(=160\times\dfrac3{10}\\\\=16\times3=48\)

Hence, Number of water bottles a team can fill  from a single watercooler = 48

Number of water bottle IT team can feel a single watercooler =48

Step-by-step explanation:

From that 80 college students, the probability that at most 60 say that they drink coffee during exam week  is 0.3085

This is a binomial distribution problem in which we want to know the probability it is that at least 60 students out of 80 choose to drink coffee during test week.

Here, we have:

n = 80 (number of trials)

p = 0.67 (probability of success in each trial)

q = 1 - p = 0.33 (probability of failure in each trial)

x ≤ 60 (number of successes we want to find the probability for)

This probability may be calculated using the binomial cumulative distribution function (CDF). The binomial CDF formula is as follows:

P(X ≤ k) = Σi=\(0^{K}\) (\(_{n}C^{i} }\)) * \(p^{i}\) * (\((1-p)^{n-i}\)

We can determine the chance of having 60 or fewer successes using this formula:

P(X ≤ 60) = Σi=\(0^{60}\) (\(_{80} C^{i}\)) * \(0.67^{i}\) * \(0.33^{80-i}\)

P(X ≤ 60) = 0.3085

As a result, the probability that at least 60 college students claim they consume coffee during test week is 0.3085, or around 31%. As a result, 0.3085 is the correct answer.

Equation: \( 4x\degree + 2x\degree = 180°\)

Answer:

120°, 60°

Step-by-step explanation:

Since, sum of any two Supplementary angles is always 180°.

\( \therefore 4x\degree + 2x\degree = 180°\\

\therefore 6x\degree = 180°\\

\therefore 6x = 180\\\\

\therefore x = \frac{180}{6}\\\\

\therefore x = 30\\

4x° = (4\times 30)° = 120°\\

There are three main categories of fractions in mathematics. Proper fractions, incorrect fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions. We categorize its types based on these two terms.

The terminology used to identify the components of a whole object are fractions. For instance, if a pizza is cut into four pieces, each piece is equal to one-fourth of the pizza. Here, the numerator is 1, and the denominator is 4.

Answer:

A conditional statement is something like:

P = hypothesis.

Q = conclusion.

In this case, we have:

"If a polygon is a quadrilateral, then it is a square".

1) The hypothesis is: a polygon is a quadrilateral

2) The conclusion is:  it is a square

3) It is not true, because there are other quadrilaterals that are not squares, for example, the rectangles.

4) The inverse of a conditional statement is (using the same notation than above)

If not P, then not Q.

In this case is:

"If a polygon is not a quadrilateral, then it is not a square"

5) A converse statement is:

If Q, then P
