To solve x^2 - 12x + 8 = 0 by completing the square, we can follow these steps:

Move the constant term to the right side:

x^2 - 12x = -8

Take half of the coefficient of x, square it, and add it to both sides of the equation:

x^2 - 12x + (-12/2)^2 = -8 + (-12/2)^2

Simplifying the right side:

x^2 - 12x + 36 = -8 + 36

Factor the left side:

(x - 6)^2 = 28

Take the square root of both sides:

x - 6 = ±√28

Add 6 to both sides:

x = 6 ±√28

Simplify the roots:

x = 6 ±2√7

Therefore, the solutions to the equation x^2 - 12x + 8 = 0 by completing the square are x = 6 + 2√7 and x = 6 - 2√7.

The time required to have number of bacteria to be 100,000 is equal to 15.96 hours.

Let us consider,

N = final number of bacteria

   = 100,000 bacteria

N₀ = initial number of bacteria

    = 2500 bacteria

t = time elapsed

T = time it takes for the population to double

   = 3 hours

Use exponential growth formula to solve this problem,

N = N₀ × 2^(t/T)

Substitute the values in the formula,

⇒ 100,000 = 2500 × 2^(t/3)

Simplify this equation by dividing both sides by 2500,

⇒ 100,000/2500 = 2^(t/3)

⇒ 40 = 2^(t/3)

To solve for t, we can take the logarithm of both sides of the equation,

⇒ log40 = (t/3) log 2

⇒ t/3 = log 40 /log 2

⇒t = 3 × ( log 40 /log 2)

Using a calculator, we can evaluate this expression to get,

t ≈ 15.96 hours

Therefore, it will take approximately 15.96 hours for the number of bacteria to reach 100,000.

The position of sea horse after lower & higher elevations with help of representing it as integers is:

a)The total elevation of the sea horse = 24 feet lower

b)The position of the sea horse = on the sea level.(elevation = 0)

In second part of the story, the answer to the elevation woas zero.

What are integers?

The negative numbers as well as all whole numbers are considered integers.  Integers are created when we combine negative and full numbers. Integers are represented on a number line with negatives to the left of zero and positives to the right. The entire number, zero, is neither positive nor negative. Every negative number is less than zero, as are all positive numbers.Greater than the farthest-from-zero negative integer is the negative number that is less than zero.

Given that the elevation of sea horse is -12 feet.

a)Initial position of seahorse= 12 feet below sea level

                                           = - 12 feet.

Drift in position due to strong current=12 feet lower in elevation

                                                              = -12 feet

Total elevation below sea level = -12 + (-12)

                                                    = -12-12

                                                    = -24 feet below sea level.

The elevation of the sea horse = 24 feet lower

b)Initial position of seahorse= 12 feet below sea level

                                           = - 12 feet.

Drift in position due to strong current=12 feet higher in elevation

                                                              = +12 feet

Total elevation below sea level = -12 + (+12)

                                                    = -12 + 12

                                                    = 0 feet below sea level.

The null hypothesis in the chi-square test of hypothesis states that the two categorical variables under consideration are independent of each other, meaning that there is no relationship or association between them.

In the chi-square test of hypothesis, the null hypothesis states that the variables under consideration are independent. That is, there is no relationship between the two variables being studied.

The chi-square test is a statistical method used to determine if two categorical variables are associated or independent. Categorical variables are those that take on values that are categories or labels.

For example, gender (male or female) or educational level (high school, college, graduate school) are categorical variables.

The chi-square test determines the expected frequency of each category based on the null hypothesis, which assumes independence between the two variables.

The observed frequency is then compared to the expected frequency, and if the difference is significant enough, it suggests that the null hypothesis should be rejected, and the two variables are considered to be associated or dependent.

Therefore, in summary, the null hypothesis in the chi-square test of hypothesis states that the two categorical variables under consideration are independent of each other, meaning that there is no relationship or association between them.

The probability of getting 2 or fewer women when 11 people are picked is approximately 0.0332

To solve this problem, we can use the binomial distribution formula, which gives us the probability of getting k successes in n independent trials, where the probability of success in each trial is p.

In this case, our "success" is selecting a woman, and our "failure" is selecting a man. Since there are approximately equal numbers of men and women in the pool of applicants, the probability of selecting a woman is p = 0.5, and the probability of selecting a man is q = 1 - p = 0.5.

We want to find the probability of getting 2 or fewer women when 11 people are picked, so we need to calculate the probability of getting 0, 1, or 2 women.

P(0 women) = C(11,0) × (0.5)^0 × (0.5)^11 = 0.00048828125

P(1 woman) = C(11,1) × (0.5)^1 × (0.5)^10 = 0.00537109375

P(2 women) = C(11,2) × (0.5)^2 × (0.5)^9 = 0.02734375

where C(n,k) represents the number of ways to choose k items from a set of n items, which is also known as the binomial coefficient.

Therefore, the probability of getting 2 or fewer women when 11 people are picked is

P(0, 1, or 2 women) = P(0 women) + P(1 woman) + P(2 women)

= 0.00048828125 + 0.00537109375 + 0.02734375

To make the probability greater than 0.12 that there are at least two people born on the same day of the week, we need at least 21 people chosen at random.

To solve the problem, we can use the concept of the pigeonhole principle.

The probability that no two people share the same birth day of the week is given by:

P(No two people share the same birth day of the week) = 7/7 x 6/7 x 5/7 x … x [(7-(n-1))/7]

Here, n is the number of people chosen at random. The first person can be born on any day of the week. The probability that the second person is born on a different day of the week is 6/7. The probability that the third person is born on a day of the week different from the first two is 5/7, and so on.

The probability that at least two people share the same birth day of the week is

P(At least two people share the same birth day of the week) = 1 - P(No two people share the same birth day of the week)

We want to find the smallest value of n for which P(At least two people share the same birth day of the week) is greater than 0.12.

1 - P(No two people share the same birth day of the week) > 0.12

P(No two people share the same birth day of the week) < 0.88

Using a calculator or a spreadsheet, we can find that n = 21 is the smallest value that satisfies this inequality. Therefore, we need at least 21 people chosen at random to make the probability greater than 0.12 that there are at least two people born on the same day of the week.

The solution of the equation log(t - 3) = log(17 - 4t), is 4.

option A.

To find the solution for the equation log(t - 3) = log(17 - 4t), we can use the properties of logarithms.

Step 1: Remove the logarithms on both sides.

Applying the property of logarithms that states log(a) = log(b) if and only if a = b, we can remove the logarithms from both sides of the equation:

t - 3 = 17 - 4t

Step 2: Add 4t to both sides.

Adding 4t to both sides of the equation to isolate the t term on one side:

t + 4t - 3 = 17

Step 3: Combine like terms.

Combining like terms on the left-hand side:

5t - 3 = 17

Step 4: Add 3 to both sides.

Adding 3 to both sides of the equation to isolate the t term:

5t - 3 + 3 = 17 + 3

5t = 20

Step 5: Divide by 5.

Dividing both sides of the equation by 5 to solve for t:

0.30x + 0.35y = 5.80

where x is the number of 30¢ cards and y is the number of 35¢ cards.

Next, we are given the information that the number of 30¢ cards is six more than one half the number of 35¢ cards. Using the unitary method, we can set up an equation that relates the number of 30¢ cards to the number of 35¢ cards:

x = 0.5y + 6

Now we can use this equation to eliminate x from our first equation:

0.30(0.5y + 6) + 0.35y = 5.80

Simplifying this equation gives:

0.15y + 1.80 + 0.35y = 5.80

0.50y = 4.00

y = 8

So there are 8 35¢ cards in the box. We can use the unitary method again to find the number of 30¢ cards:

The product rule states that the derivative of the product of two functions is equal to the first function multiplied by the derivative of the second function plus the second function multiplied by the derivative of the first function.

Let's apply the product rule to our function Z:

First, we differentiate the first function e⁻⁴ˣ with respect to x. The derivative of e⁻⁴ˣ is -4e⁻⁴ˣ.

Next, we differentiate the second function cos(4πt) with respect to t. The derivative of cos(4πt) is -4πsin(4πt).

Therefore, the differential function of Z is:

dZ/dt = -4e⁻⁴ˣcos(4πt) - 4πsin(4πt)e⁻⁴ˣ

If Taylor is proving the Pythagorean theorem.  Taylor can use the diagram to prove the Pythagorean theorem by: A. Taylor could set the area of a square with side length a + b equal to the sum of the areas of the 4 triangles and the square with side length c.

To prove the Pythagorean theorem, we want to show that in a right triangle with legs a and b and hypotenuse c, the square of the hypotenuse c^2 is equal to the sum of the squares of the legs a^2 + b^2.

From the given diagram, we can see that we have a square with side length a+b, which is divided into 4 congruent right triangles and a smaller square with side length c. Each of the 4 triangles has legs a and b, which are also the legs of the right triangle we want to prove the theorem for. The smaller square with side length c has an area equal to c^2, which is the square of the hypotenuse of the right triangle.

The area of the square with side length a+b is (a+b)^2 = a^2 + 2ab + b^2. The area of one of the congruent right triangles is (1/2)ab, so the sum of the areas of the 4 triangles is 2ab. Therefore, the sum of the areas of the 4 triangles and the smaller square is:

a^2 + 2ab + b^2 + c^2

But this is also equal to the area of the larger square with side length a+b, which is (a+b)^2. So we have:

a^2 + 2ab + b^2 + c^2 = (a+b)^2

Expanding the right-hand side gives:

a^2 + 2ab + b^2 + c^2 = a^2 + 2ab + b^2

Canceling the common terms on both sides gives:

c^2 = a^2 + b^2

This is the Pythagorean theorem, which we have proved using the given diagram.

Therefore, option A is the correct answer.

The constant of proportionality is $8.40

The constant of proportionality is a value that relates two quantities that are proportional to each other. It is represented by the letter k and is found by dividing the dependent variable by the independent variable. In this case, the constant of proportionality is $8.40 for the given data set.

According to the given information:

To find the constant of proportionality, we can use any two data points from the table and plug them into the equation y = kx.

Let's use the first and second data points: (0.75, $6.30) and (2.5, $21.00).

We can set up the equation as:

$6.30 = k(0.75)

Solving for k, we get:

k = $6.30/0.75 = $8.40

Now, we can check our work by using another data point. Let's use the third data point: (4, $33.60).

Plugging in the values, we get:

$33.60 = k(4)

k = $33.60/4 = $8.40

Since we get the same value for k, we can be confident that our answer is correct.

Therefore, the constant of proportionality is $8.40.
