Step-by-step explanation:

The probability that your two cards in a 6-card deck of Blackjack will be greater than 16 is 1/5 or 0.2.

To find the probability that your two cards in a 6-card deck of Blackjack will be greater than 16, we'll need to first determine the possible card values and the combinations that result in a sum greater than 16.

Then, we can calculate the probability.

The probability that your two cards in a 6-card deck of Blackjack will be greater than 16 can be calculated by following these steps:

1. Determine the card values: In Blackjack, cards 2-10 are worth their face value, Jack, Queen, and King are worth 10, and Ace can be 1 or 11. In a 6-card deck, we can have cards with values {2, 3, 4, 5, 6, Ace}.

2. Find the combinations resulting in a sum greater than 16: Using the card values mentioned above, the possible combinations are {(6, Ace), (5, Ace), (4, Ace)}.

3. Calculate the probability: There are a total of 15 possible 2-card combinations (6 choose 2), and 3 of those combinations result in a sum greater than 16. So, the probability is:

Probability = Number of desired outcomes / Total possible outcomes
Probability = 3/15

4. Simplify the fraction: The probability can be simplified to 1/5 or 0.2.

Therefore, the probability that your two cards in a 6-card deck of Blackjack will be greater than 16 is 1/5 or 0.2.

The numerical length of line segment AC is 25.

A line segment refers to a straight line connecting two points.

If point B is on line segment AC, then point B divides the line segment into segments AB and BC.

AB + BC = AC

Given that AB =2x + 10, BC = x, and AC = 5x, substitute these expressions in the equation AB + BC = AC.

AB + BC = AC

2x + 10 + x = 5x

3x + 10 = 5x

5x - 3x = 10

2x = 10

x = 5

To determine the numerical length of line segment AC, substitute the value of x in the equation AC = 5x.

AC = 5x

AC = 5(5)

AC = 25

Hence, the numerical length of line segment AC is 25.

Step-by-step explanation:

(1) y = x e^(x²)

Take derivative with respect to x:

dy/dx = x (e^(x²) 2x) + e^(x²)

dy/dx = 2x² e^(x²) + e^(x²)

dy/dx = (2x² + 1) e^(x²)

Take derivative with respect to x again:

d²y/dx² = (2x² + 1) (e^(x²) 2x) + (4x) e^(x²)

d²y/dx² = (4x³ + 2x) e^(x²) + 4x e^(x²)

d²y/dx² = (4x³ + 6x) e^(x²)

Substitute:

d²y/dx² − 2x dy/dx − 4y

= (4x³ + 6x) e^(x²) − 2x (2x² + 1) e^(x²) − 4x e^(x²)

= 4x³ + 6x − 2x (2x² + 1) − 4x

= 4x³ + 6x − 4x³ − 2x − 4x

= 0

(2) y = sin⁻¹(√x)

sin y = √x

sin²y = x

Take derivative with respect to x:

2 sin y cos y dy/dx = 1

sin(2y) dy/dx = 1

dy/dx = csc(2y)

Take derivative with respect to x again:

d²y/dx² = -csc(2y) cot(2y) 2 dy/dx

d²y/dx² = -2 csc²(2y) cot(2y)

Substitute:

2x (1 − x) d²y/dx² + (1 − 2x) dy/dx

= 2 sin²y (1 − sin²y) (-2 csc²(2y) cot(2y)) + (1 − 2 sin²y) csc(2y)

Use power reduction formula:

= (1 − cos(2y)) (1 − ½ (1 − cos(2y))) (-2 csc²(2y) cot(2y)) + (1 − (1 − cos(2y))) csc(2y)

= (1 − cos(2y)) (1 − ½ + ½ cos(2y)) (-2 csc²(2y) cot(2y)) + cos(2y) csc(2y)

= (1 − cos(2y)) (½ + ½ cos(2y)) (-2 csc²(2y) cot(2y)) + cot(2y)

= (cos(2y) − 1) (1 + cos(2y)) csc²(2y) cot(2y) + cot(2y)

= (cos²(2y) − 1) csc²(2y) cot(2y) + cot(2y)

= -sin²(2y) csc²(2y) cot(2y) + cot(2y)

= -cot(2y) + cot(2y)

The simplest way to perform a division is long division and synthetic division.

What is division?

Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.

There are two methods to perform division:

Long division: The mathematical procedure for splitting big numbers into more manageable groups or sections is known as long division. A difficulty can be solved by breaking it down into manageable parts. Dividends, divisors, quotients, and remainders all exist in long divisions.

Synthetic division: In algebra, synthetic division is a technique for manually dividing polynomials according to Euclid, requiring less writing and calculation than long division. Although the approach can be applied to division by any polynomial, it is often taught for division by linear monic polynomials.

The probability that the sum of two fair six-sided dice is 9 or 99 or higher is 5/36.

To find the probability of whether the sum of two fair six-sided dice is 9 or 99 or higher, we need to determine the number of favorable outcomes and the total number of possible outcomes.

The possible outcomes when rolling two six-sided dice range from 2 (minimum sum) to 12 (maximum sum). We want to calculate the probability of getting a sum of 9 or 99 or higher.

To determine the favorable outcomes, we need to identify all the combinations of dice rolls that meet our criteria. Here are the favorable outcomes:

(3, 6) = sum of 9

(4, 5) = sum of 9

(5, 4) = sum of 9

(6, 3) = sum of 9

(6, 6) = sum of 12

Therefore, we have 5 favorable outcomes.

Now, let's calculate the total number of possible outcomes. Since each die has 6 possible outcomes (numbers 1 to 6), the total number of possible outcomes for rolling two dice is 6 * 6 = 36.

The probability of getting a sum of 9 or 99 or higher is given by:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 5 / 36

Therefore, the probability that the sum of two fair six-sided dice is 9 or 99 or higher is 5/36.

Step-by-step explanation:

Unfortunately other people have promised to give Brainliest before and they never did. However, I'll answer the third question and tell you that it's 8 sides.

1. The amount borrowed is $3,000.

2. The ordinary interest is $80.

1. To find the amount borrowed, we can use the formula I = (P x i x t), where I is the interest, P is the principal (amount borrowed), i is the interest rate, and t is the time in years. Rearranging the formula, we have P = I / (i x t). Plugging in the given values, P = 270 / (0.09 x (2/12)) = $3,600.

2. To find the ordinary interest, we can again use the formula I = (P x i x t), where I is the interest, P is the principal, i is the interest rate, and t is the time in years. Since the time given is in days, we need to convert it to years. So, t = 60 / 365 = 0.1644 years. Plugging in the values, I = 4000 x 0.12 x 0.1644 = $79.07.

1. The amount borrowed, we can rearrange the formula TA = P + I to solve for P (the principal amount). Given that the interest (I) is $270, the interest rate (i) is 9%, and the time (t) is two months, we can substitute these values into the formula.

P = I / (i x t)

P = $270 / (0.09 x 2)

Calculating this expression gives us:

P = $1,500

Therefore, the amount borrowed is $1,500.

Using the formula TA = P + I, we can rearrange it to solve for P:

P = TA - I

In this case, the total amount (TA) is the amount borrowed plus the interest. We are given that the interest is $270, and we need to find the principal amount (P) when the interest rate (i) is 9% and the time (t) is two months.

Substituting the given values into the formula, we have:

P = $270 / (0.09 x 2)

Simplifying the expression, we get:

P = $270 / 0.18

Calculating this expression gives us:

P = $1,500

Therefore, the amount borrowed is $1,500.

2. To find the ordinary interest for a loan of $4,000, at 12%, for 60 days, we can use the formula I = (P x i x t). Given that the principal amount (P) is $4,000, the interest rate (i) is 12%, and the time (t) is 60 days, we can substitute these values into the formula.

I = (P x i x t)

I = ($4,000 x 0.12 x 60) / 365

Calculating this expression gives us:

I ≈ $78.08 (rounded to two decimal places)

Therefore, the ordinary interest for the loan is approximately $78.08.

Explanation and Calculation:

Using the formula I = (P x i x t), we can calculate the ordinary interest for the loan.

In this case, the principal amount (P) is $4,000, the interest rate (i) is 12%, and the time (t) is 60 days.

Substituting the given values into the formula, we have:

I = ($4,000 x 0.12 x 60) / 365

Simplifying the expression, we get:

I ≈ $78.08

Therefore, the ordinary interest for the loan is approximately $78.08.

The four basic measurements that serve as the foundation for other units of measure are length, mass, time, and temperature.

Length is a measure of distance between two points, typically measured in meters (m) within the International System of Units (SI). Mass is the amount of matter in an object, measured in kilograms (kg) in the SI system. Time refers to the duration or interval between events and is measured in seconds (s) within the SI system.

Lastly, temperature is a measure of the average kinetic energy of particles in a substance, represented in degrees Celsius (°C) or Kelvin (K) in the SI system.

All other units of measure are defined and compared to these four basic measurements. For instance, speed is derived from the combination of length and time (e.g., meters per second). Similarly, force is derived from mass and acceleration, which itself is derived from the change in velocity over time (e.g., newtons).

The combination and comparison of these fundamental measurements enable scientists, engineers, and other professionals to quantify and analyze various phenomena in the physical world.

The generating function for sn can be found using a recursive approach.

First, let's consider the base cases:
- For n = 0, there are no ternary sequences, so s0 = 1
- For n = 1, there are three possible ternary sequences (0, 1, 2), so s1 = 3
- For n = 2, there are six possible ternary sequences without consecutive 0's (01, 02, 10, 12, 20, 21), so s2 = 6

Now, let's consider the recursive case for n > 2. There are two possibilities for the first digit of a ternary sequence of length n:
- If the first digit is 0, then the second digit cannot be 0, so there are 2 options for the second digit and sn-2 options for the remaining n-2 digits. This gives us a total of 2*sn-2 possibilities.
- If the first digit is not 0, then there are 2 options for the first digit and sn-1 options for the remaining n-1 digits. This gives us a total of 2*sn-1 possibilities.

Adding these two possibilities together, we get the recursive formula: sn = 2*sn-1 + 2*sn-2

The generating function for this sequence is given by the following power series:
S(x) = s0 + s1*x + s2*x^2 + s3*x^3 + ...

Substituting the recursive formula into the power series and rearranging terms, we get:
S(x) = 1 + 3*x + 6*x^2 + (2*S(x) - 2)*x^2 + (2*S(x) - 4)*x^3 + ...

Solving for S(x), we get:
S(x) = (1 + x)/(1 - 2*x - 2*x^2)

Therefore, the generating function for sn is S(x) = (1 + x)/(1 - 2*x - 2*x^2).

The formula for the area of a trapezoid is (1/2)(b1 + b2)h, where b1 and b2 are the lengths of the bases, and h is the height.

Describe the trapezoid shape.

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

We know that the area is 104 square centimeters and the height is 8 centimeters, we can use that to find the length of the second base.

104 = (1/2)(b1 + b2) * 8

104 = (1/2)(12+b2) * 8

104 = (1/2)(12+b2) * 8

104 = 6 + 4b2

98 = 4b2

b2 = 98/4 = 24.5 cm
