Answer:

w = -12

Step-by-step explanation:

You basically have 90% of the question done. You just needed to divide -60 by 5 and then get -12.

Good Luck!!!!!

=====================================================

Explanation:

You're on the right track. You start off subtracting 35 from both sides, and then next divide both sides by 5. Your steps are 100% correct. The last thing to do is to simplify each side after what you wrote. The -60/5 on the left simplifies to -12, while the 5w/5 on the right simplifies to w. We end up with -12 = w and that's the same as w = -12.

--------------

To verify, replace every copy of 'w' with -12 in the original equation and simplify each side.

-25 = 35 + 5w

-25 = 35 + 5(-12)

-25 = 35 - 60

-25 = -25

We end up with the same thing on both sides, so the answer is confirmed.

The method that is invoked when an object is created is known as a constructor method.

Constructor in C++ is a special method that is invoked automatically at the time of object creation. It is used to initialize the data members of new objects generally.

The constructor in C++ has the same name as the class or structure. Constructor is invoked at the time of object creation. It constructs the values i.e. provides data for the object which is why it is known as constructors.

Constructor does not have a return value, hence they do not have a return type.

The prototype of Constructors is as follows:

<class-name> (list-of-parameters);

Constructors can be defined inside or outside the class declaration:-

The syntax for defining the constructor within the class:

<class-name> (list-of-parameters) { // constructor definition }

The syntax for defining the constructor outside the class:

<class-name>: :<class-name> (list-of-parameters){ // constructor definition}

Answer:

Inverse relationship

Step-by-step explanation:

The equation we are looking at is;

y = 87.2/x

which implies xy = 87.2

If it was a direct relationship

y = constant * x

if it was inverse, it would have been

y * x = constant

since 87.2 is a constant, the question looks exactly like the second scenario.

This means that what we have is an inverse relationship

The car will cost $ 800 after a depreciation time of approximately 6 years.

Herein we are informed about the case of a car bought in 2011 at a cost of $ 36,000 and that depreciates linearly every year. Then, the depreciation function is described below:

c(t) = c' + m · t

Where:

If we know that c(0) = 36,000, c(4) = 12,000 and c(t) = 800, then the depreciation rate is:

m = (12,000 - 36,000) / (4 - 0)

m = - 24,000 / 4

m = - 6,000

800 = 36,000 - 6,000 · t

6,000 · t = 35,200

t = 35,200 / 6,000

t = 5.867

The expected depreciation time is approximately 6 years.

Step-by-step explanation:

The length of LN is approximately 101.12 cm.

What is the length of the hypotenuse?

In a right triangle, the hypotenuse is the side opposite to the right angle and it is the longest side of the triangle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In a right triangle, the length of the hypotenuse is given by the Pythagorean theorem: c^2 = a^2 + b^2.

In this case, we are given that LN is the hypotenuse, and LP and MN are the other two sides.

We are also given that LP = 100 and MN = 15, and that angle PLN = PNL which means that the triangle is a right triangle.

We can use the Pythagorean theorem to find the length of LN:

LN^2 = LP^2 + MN^2

LN^2 = 100^2 + 15^2

LN^2 = 10000 + 225

LN^2 = 10225

LN = √10225

LN ≈ 101.12 cm

So the length of LN is approximately 101.12 cm.

Step-by-step explanation:

Therefore, the insect population will remain stable, neither increasing nor decreasing and the estimated  stable population is 2.

Given the equation:3-12+16 PO) 15-2+1

In order to determine the stability of a population of insects, we must first calculate the equilibrium value of PO.

A population's equilibrium is defined as the point at which the population remains stable over time, indicating that the population is neither declining nor growing indefinitely.

Stable population equilibrium is defined as follows:

Let P* be the equilibrium value of the population.

This implies that:P* = 15 - 2 + 1 / 3 - 12 + 16

This simplifies to:P* = 14/7 or 2

Therefore, the equilibrium value of the insect population is 2. If the population is greater than 2, it will decrease. If it is less than 2, it will increase.

In this case, the population of insects will settle into an equilibrium state.

The value of the stable population is 2.

The exact position of x=45.5 can be indicated on this curve using the corresponding z-score.

Assuming a normal distribution with mean μ=40 and standard deviation σ=2, we can use the standard normal distribution curve to determine the position of x=45.5.

First, we calculate the z-score of x=45.5 using the formula:

z = (x - μ) / σ

Substituting the given values, we get:

z = (45.5 - 40) / 2

z = 2.75

This means that x=45.5 is 2.75 standard deviations above the mean.

A standard normal distribution table or a calculator to find the area under the curve to the left of z=2.75.

This area represents the proportion of values that are less than or equal to z=2.75.

Using a calculator, we find that the area to the left of z=2.75 is approximately 0.997.

This means that about 99.7% of values in a normal distribution are less than or equal to x=45.5.

On the standard normal distribution curve, the value of z=2.75 is located to the right of the mean, and the area under the curve to the left of z=2.75 is shaded.

The given x value of x = 45.5 falls to the right of the mean (μ) on the normal distribution curve.

In a normal distribution, the mean (μ) represents the center of the distribution, and the standard deviation (σ) determines the spread of the data. The normal distribution is symmetric, so values to the left of the mean are smaller, while values to the right are larger.

Given x = 45.5, which is greater than the mean μ = 40, we can infer that the corresponding point on the normal distribution curve would be to the right of the mean. The exact location of x = 45.5 on the curve would depend on the standard deviation σ.

The standard deviation σ = 2 provides information about how the data is spread around the mean. However, without further information, we cannot determine the specific position of x = 45.5 on the curve relative to the standard deviation.

The exact solutions for the equation are given in terms of x and y. There are multiple possibilities depending on the specific equation, but the solutions can be expressed using mathematical notations and symbols.

The exact solutions of an equation are the specific values of the variables that satisfy the equation. Since you haven't provided a specific equation, I'll explain the concept in a general sense. In mathematics, equations can be linear, quadratic, cubic, or of higher degrees, and the solutions can vary accordingly.

For linear equations in two variables, x and y, the solutions can be expressed as ordered pairs (x, y) that satisfy the equation. Each ordered pair represents a point on the Cartesian plane, where the equation holds true.

For quadratic equations, the solutions can be found using the quadratic formula: x = (-b ± √(\(b^2\) - 4ac))/(2a), where a, b, and c are coefficients of the quadratic equation. These solutions can also be expressed as ordered pairs (x, y) by substituting the values of x into the equation to find the corresponding values of y.

Similarly, for cubic equations or higher degrees, there are different methods and formulas to find the exact solutions. These solutions involve more complex mathematical expressions and may require numerical methods for approximation.

In conclusion, the exact solutions of an equation depend on its specific form and can be expressed using mathematical symbols and notations. The solutions can be represented as ordered pairs (x, y) or as individual values of x and y, depending on the equation and the variables involved.

The probability of having 14 purines out of 20 microrna is 0.2208.

The probability of having 14 purines out of 20 microrna can be calculated using the binomial probability formula. This formula states that the probability of having a certain number of successes (in this case, purines) out of a given number of trials (the microrna) is equal to the number of ways to get that number of successes, multiplied by the probability of success for each trial, to the power of the number of successes.

The formula is as follows: P(x successes) = \(nCx * p^x * (1-p)^(n-x)\).

In this case, n = 20, x = 14, p = 0.7. Therefore, the probability of having 14 purines out of 20 microrna is 0.2208.

To calculate this, we can first calculate nCx, which is the number of ways to get 14 successes out of 20 trials. This is equal to \(20!/14!(20-14)!\) which is \(20*19*18*17*16*15/14!\), which simplifies to 4845. We can then multiply this by 0.7^14 and (1-0.7)^6 (the probability of success for each trial and the number of trials that didn't result in success), which gives us 0.2208.

Therefore, the probability of having 14 purines out of 20 microrna is 0.2208.
