The value of ratio of lime juice to mint is 3/2.

And the amount of lime juice is 3/2 of the amount of mint leaves.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

The ratio of lime juice to mint is 3/4: 1/2. therefore the value of this ratio = 3/4 ÷ 1/2 = 3/2

therefore the amount of lime juice = 1/2 × 3/2 = 3/4

10                   390

15                   585

20                   780

To find the unit rate, we need to divide the number of students by the number of teachers. For example, for the first row, the unit rate would be:

Unit rate = students/teachers = 130/5 = 26 students per teacher

We can repeat this calculation for each row:

For the second row, the unit rate is 390/10 = 39 students per teacher.

For the third row, the unit rate is 585/15 = 39 students per teacher (same as the previous row).

For the fourth row, the unit rate is 780/20 = 39 students per teacher (again, the same as the previous rows).

So, the unit rate is 39 students per teacher.

If there are 17 teachers, we can use the unit rate to find the number of students:

Number of students = unit rate x number of teachers

Number of students = 39 x 17 = 663

Therefore, if there are 17 teachers, there are 663 students.

The quotient of -2 1/2 and -3 1/3 is = 9/16

In the end, the quotient is what we obtain when we divide a number. Putting things into equal groups is a division operation in mathematics. It is symbolised by the glyph (). For instance, there are three groups of 15 balls each that must be distributed equally.

When we divide the balls into three equal groups, the division formula is 15/3 = 5. The quotient is 5 in this case. This indicates that each set of balls will include five balls.

In this case let us first convert the improper fractions into proper fractions:

-2 1/2 = -4+1/2 = -3/2

-3 1/3 = -9+1/3 = -8/3

Answer:

(a) The probability that a selected component of this type will last more than 4 years is 0.69.

(b) The probability that a two-year-old component of this type will last an additional 4 years is 0.57.

(c) The 25th percentile of the lifetimes of such components is 3.38 years.
Explanation:

(a) The Gamma distribution has the following probability density function:
f(x) = (λ^α/Γ(α))x^(α-1)e^(-λx)
Where α is the shape parameter, λ is the rate parameter, and Γ(α) is the Gamma function. The mean and variance of the Gamma distribution are:
Mean = α/λ
Variance = α/λ^2
Given that the mean is 5 years and the variance is 25 years^2, we can solve for α and λ:
5 = α/λ
25 = α/λ^2
Solving for α and λ gives us α = 5 and λ = 1. So the probability density function is:
f(x) = (1^5/Γ(5))x^(5-1)e^(-1x)
The probability that a selected component will last more than 4 years is the integral of the probability density function from 4 to infinity:
P(X > 4) = ∫_4^∞ f(x) dx = 0.69

(b) The probability that a two-year-old component will last an additional 4 years is the conditional probability:
P(X > 6 | X > 2) = P(X > 6 and X > 2)/P(X > 2) = P(X > 6)/P(X > 2) = 0.57

(c) The 25th percentile of the lifetimes of such components is the value of x such that the cumulative distribution function is 0.25:
F(x) = 0.25
∫_0^x f(x) dx = 0.25
Solving for x gives us x = 3.38 years.

a. To complete the table of values, we need to plug in the given values of d into the equation v(d) = √12d and solve for v.

For d = 30:
v(30) = √12(30) = √360 = 18.97 mph

For d = 50:
v(50) = √12(50) = √600 = 24.49 mph

For d = 60:
v(60) = √12(60) = √720 = 26.83 mph

The polynomial in factored form as a product can be found by using the factor theorem and synthetic division. The factor theorem states that if f(a) = 0, then (x-a) is a factor of f(x). We can use synthetic division to find the factors of f(x)=12x^(5)+5x^(4)-39x^(3)+9x^(2)+19x-6.

First, we need to find a value of x that makes f(x) = 0. We can use the rational root theorem to find possible rational roots. The possible rational roots are ±1, ±2, ±3, ±6. We can use synthetic division to test these possible roots.

Using synthetic division with x = 1, we get a remainder of -1, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of f(x).

Now we can divide f(x) by (x+1) using synthetic division to get the quotient 12x^(4)-7x^(3)-32x^(2)+41x-6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this quotient.

The possible rational roots of the quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of 8, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of the quotient.

We can divide the quotient by (x+1) using synthetic division to get the new quotient 12x^(3)-19x^(2)-13x+6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this new quotient.

The possible rational roots of the new quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of -14, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 0, so x = -1 is a root and (x+1) is a factor of the new quotient.

We can divide the new quotient by (x+1) using synthetic division to get the new quotient 12x^(2)-31x+6. We can repeat the process of finding possible rational roots and using synthetic division to find the factors of this new quotient.

The possible rational roots of the new quotient are ±1, ±2, ±3, ±6. Using synthetic division with x = 1, we get a remainder of -13, so x = 1 is not a root. Using synthetic division with x = -1, we get a remainder of 49, so x = -1 is not a root. Using synthetic division with x = 2, we get a remainder of 0, so x = 2 is a root and (x-2) is a factor of the new quotient.

We can divide the new quotient by (x-2) using synthetic division to get the new quotient 12x-3. This quotient cannot be factored further, so the factors of f(x) are (x+1)(x+1)(x+1)(x-2)(12x-3).

Therefore, the polynomial in factored form as a product is f(x) = (x+1)(x+1)(x+1)(x-2)(12x-3).

It will take the second skater 20 seconds to catch up to the first skater and pass him/her.

In physics, speed and motion are related concepts that describe the movement of objects in space.

Speed is a scalar quantity that measures how fast an object is moving. It is the rate at which an object covers distance, typically measured in meters per second (m/s), kilometers per hour (km/h), or some other unit of distance per unit of time.

Motion, on the other hand, is the change in position of an object over time, with respect to a reference point. In physics, motion can be described in terms of displacement, velocity, and acceleration. Displacement refers to the change in position of an object relative to a reference point, while velocity describes how fast an object is moving in a specific direction.

Acceleration refers to the rate at which an object's velocity changes over time, either by increasing or decreasing in speed or changing direction.

In summary, speed is a measure of how fast an object is moving, while motion is the change in position of an object over time.

We can start by setting up an equation to represent the distance each skater travels, with t representing the time it takes for the second skater to catch up to the first skater:

Distance traveled by the first skater = Distance traveled by the second skater + 40 meters

Using the formula distance = rate × time, we can plug in the given rates and the unknown time to get:

12t + 40 = 14t

Simplifying this equation, we get:

40 = 2t

t = 20 seconds

Therefore, it will take the second skater 20 seconds to catch up to the first skater and pass him/her.

The number of total books there to start with were 70

Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

Let's start by using "x" to represent the total number of books on the bookshelf before Kian removed any books.

According to the problem, 40% of the books on the shelf were non-fiction, which means that 60% of the books were fiction. We can express this as an equation:

0.4x = number of non-fiction books

0.6x = number of fiction books

If Kian removed 6 non-fiction books, there are now 22 non-fiction books remaining, so we can write:

0.4x - 6 = 22

Solving for x, we can add 6 to both sides and then divide by 0.4:

0.4x = 28

x = 70

Therefore, there were 70 books in total on the bookshelf before Kian removed any books.

A triangle is a closed two-dimensional shape with three straight sides and three angles. It is the simplest polygon that can be formed in Euclidean geometry, and it is widely studied in mathematics and geometry. Triangles can be classified based on their sides and angles. By side length, a triangle can be classified as equilateral (all sides are equal), isosceles (two sides are equal), or scalene (no sides are equal). By angle measure, a triangle can be classified as acute (all angles are less than 90 degrees), obtuse (one angle is greater than 90 degrees), or right (one angle is exactly 90 degrees). Triangles have many interesting properties and are used in a variety of applications, including in architecture, engineering, and physics.

Here,

Sure, I can help you with that! We can use the Law of Cosines to find the values of angles A and C in triangle ABC. The Law of Cosines states that:

c² = a² + b² - 2ab cos(C)

where c is the side opposite angle C.

First, let's find the value of side c:

c² = a² + b² - 2ab cos(C)

c² = (782)² + (1435)² - 2(782)(1435) cos(115.6°)

c² = 613524 + 2055225 - 2238015.52

c²  = 594733.48

c = √(594733.48)

c ≈ 771.1 cm

Now, we can use the Law of Cosines again to find angle A:

cos(A) = (b² + c² - a²) / 2bc

cos(A) = (1435² + 771.1² - 782²) / (2 * 1435 * 771.1)

cos(A) = 0.2354

A = cos⁻¹*²³⁵⁴⁾

A ≈ 76.16°

Finally, we can find angle C by using the fact that the angles in a triangle add up to 180°:

C = 180° - A - B

C = 180° - 76.16° - 115.6°
