Given data:

pH of lye = 12.13

Using the formula pH = -log[H+], we have to find the hydrogen ion concentration, [H+].

Now, putting the given values in the formula, we get:

pH = -log[H+]

12.13 = -log[H+]

log[H+] = -12.13

[H+] = 10^-12.13 = 5.01187 x 10^-13

So, the hydrogen ion concentration, [H+] is 5.01187 x 10^-13 moles/liter. Therefore, the answer is 5.01187 x 10^-13.

The probability of randomly selecting a temperature between 70 and 75 is approximately 0.8291.

To find the probability that a randomly chosen temperature is between 70 and 75, we need to use the z-score formula as shown below:

z = (x - μ) / σ

Where:x = 70 and 75μ = 79σ = 4z1 = (70 - 79) / 4 = -2.25z2 = (75 - 79) / 4 = -1P(70 < x < 75) = P(-2.25 < z < -1)

To find the probability for the above inequality, we need to use a calculator. We know that the probability of the standard normal distribution is equal to 1.

Hence, P(-2.25 < z < -1) = Φ(-1) - Φ(-2.25) = 0.8413 - 0.0122 ≈ 0.8291. Therefore, the probability is about 0.8291.

Using the equation y = 7x , we can compute that when x = 2, y = 14 and when x = 4 , y = 28. So, correct option is B.

The equation y = 7x relates the variables y and x, where y is a function of x. To compute the value of y for a given value of x, we simply substitute that value of x into the equation and solve for y.

When x = 2, we can substitute this value into the equation:

y = 7(2) = 14

Therefore, when x = 2, y = 14.

Similarly, when x = 4, we can substitute this value into the equation:

y = 7(4) = 28

Therefore, when x = 4, y = 28.

So, the correct option is B: When x = 2, y = 14 and when x = 4, y = 28.

In summary, to compute the value of y for a given value of x using an equation, we substitute that value of x into the equation and solve for y. In this case, when x = 2, y = 14, and when x = 4, y = 28, according to the given equation y = 7x.

Therefore, the annual interest rate is approximately 12%.

How to compute interest is as follows: P x R x T is the formula for calculating interest. Principal Amount is P. (the beginning balance). rates of interest (usually per year, expressed as a decimal). T stands for the value T. (generally one-year time periods).

Let r be the annual interest rate as a decimal. Then the balance after 2 years is given by:

Balance = 3500(1+r)²

Setting this equal to $4390.40 and solving for r, we have:

4390.40 = 3500(1+r)²

Dividing both sides by 3500 and taking the square root, we get:

(1+r)² = 4390.40/3500 = 1.2544

Taking the square root of both sides, we get:

1 + r = √(1.2544) ≈ 1.12

Subtracting 1 from both sides, we get:

r ≈ 0.12 or 12%

Therefore, the annual interest rate is approximately 12%.

Step-by-step explanation:

By using pythagorean theorem, the length of the missing side is 12 feet.

What is the Pythagorean theorem?

Pythagoras' theorem is a fundamental principle in geometry that relates to the three sides of a right-angled triangle. It states that:

"In a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides."

In mathematical terms, if a, b, and c are the lengths of the sides of a right-angled triangle, where c is the hypotenuse, then the theorem can be written as:

[tex]c^2 = a^2 + b^2[/tex]

We can use the Pythagorean theorem to determine the length of the missing side if we know that the given sides form a right triangle.

In this case, we have two sides of the triangle given: 7.2 feet and 9.6 feet. Let's assume that c is the length of the hypotenuse.

If the triangle is a right triangle, then we can use the Pythagorean theorem to solve for c:

[tex]c^2 = 7.2^2 + 9.6^2[/tex]

[tex]c^2 = 51.84 + 92.16[/tex]

[tex]c^2 = 144[/tex]

[tex]c = \sqrt{144}[/tex]

c = 12 feet

Therefore, if the triangle is a right triangle, then the length of the missing side is 12 feet.

In the context of sampling distribution of the means, the standard deviation represents the degree of spread or variation of sample means around the true population mean.

To compute the standard deviation of the sampling distribution of the means, one typically divides the population standard deviation by the square root of the sample size.

Therefore, the standard deviation of the sampling distribution of the means is 29/√36 = 29/6 = 4.83 pounds.

A person's cycling rate can be expressed mathematically in the equation that describes their cycling motion. Specifically, the cycling rate can be represented by the frequency or number of revolutions per unit time (usually in seconds) that the person completes while cycling.

The equation that describes a person's cycling motion is typically a kinematic equation that relates the person's position, velocity, and acceleration as a function of time. One commonly used equation is:

d = vit + 1/2at^2

where d is the distance traveled by the person, vi is the initial velocity (usually zero), a is the acceleration, and t is the time elapsed.

The cycling rate can be incorporated into this equation by expressing the velocity as a function of the frequency of revolutions (f) and the radius of the wheel (r). This gives:

v = 2πrf

where v is the velocity of the cyclist, r is the radius of the wheel, and π is the mathematical constant pi (approximately 3.14).

Substituting this expression for v into the kinematic equation gives:

d = (2πrf)t + 1/2at^2

This equation shows how the person's cycling rate, represented by the frequency f, affects their distance traveled as a function of time. If the person increases their cycling rate, their velocity increases, and they will travel a greater distance in the same amount of time.

Given l = 3, w = 5 and h = 2

The cost of water from the store and the cost from the tap will be the same when the number of liters

reaches 7.5 liters.

Let's assume that the cost of buying 'x' liters of water from the store is the same as the cost of buying 'x' liters of water from the tap.

For water from the store, the cost per liter is 3, so the cost of buying 'x' liters of water from the store would be 3x.

For water from the tap, there is a flat rate of 15 plus per liter. So, the cost of buying 'x' liters of water from the tap would be 15 + x.

Now we can set up an equation to find the value of 'x' when the costs are equal:

3x = 15 + x

Simplifying this equation, we get:

2x = 15

x = 7.5

Therefore, the cost from the store and the cost from the tap would be the same at 7.5 liters.

Answer:

the number 228

Step-by-step explanation:

Let's call the smallest number in the consecutive sequence "x". Then, the 10 consecutive numbers are x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, and x+9.

If we exclude one of these numbers, then the sum of the remaining 9 numbers would be:

(x) + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) + (x+6) + (x+7) + (x+8) or 9x + 36.

We know that the sum of the remaining 9 numbers is 2023, so we can set up the equation:

9x + 36 = 2023

Solving for x, we get:

9x = 1987

x = 221

Therefore, the smallest number in the consecutive sequence is 221, and the 10 numbers are 221, 222, 223, 224, 225, 226, 227, 228, 229, and 230.

If we exclude the number 228, then the sum of the remaining 9 numbers is 2023.

The minimum number of feet in the length of the rope [tex]8\sqrt{(4\pi^2 + 36)}[/tex] feet.

To find the minimum number of feet in the length of the rope, we need to first calculate the height of the point on the circumference where the rope is attached. We can do this by using the formula for the circumference of a cylinder:

C = 2πr

where C is the circumference, r is the radius of the cylinder, and π is pi. Since we know that the circumference of the pole is 2 feet, we can solve for the radius:

2 = 2πr

r = 1/π

Next, we need to calculate the length of the rope that is wrapped around the pole. We know that the rope is wrapped around the pole four times, so the length of the rope is:

L = 4 × height of the pole

To find the height of the pole, we can use the Pythagorean theorem:

[tex]a^2 + b^2 = c^2[/tex]

where a is the radius of the pole, b is the height of the point where the rope is attached, and c is the length of the rope wrapped around the pole.

Solving for b, we get:

b = [tex]\sqrt{c^2 - a^2)}[/tex]

Substituting the values we know, we get:

b = [tex]\sqrt{((4\pi^2 + 12^2) - \pi^2)}[/tex]

b = [tex]\sqrt{sqrt(16\pi^2 + 144)}[/tex]

Finally, we can substitute this value into the formula for the length of the rope:
