An statement, rule, or law in mathematics that specifies the connection between an independent variable and a dependent variable (the dependent variable). A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. Y=X2 is an illustration of this. You only receive one output for y if you enter anything for x. The fact that x is the input value leads us to argue that y is a function of x.

The 3 consecutive odd numbers whose sum will be 51 are  16, 17, 18.

What are consecutive numbers ?

Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

Since, we know that any odd number is always of the form (2k +1). We express an odd number in this form because we know that an odd number is not divisible by 2.

Let the numbers be x, x+1 and x+2.

Then the sum is : x + x+1+ x+2 = 3x + 3

3x + 3 = 51 (given)

3x = 51 – 3 = 48

x = 48 ÷ 3

x = 16

∴

Hence , the 3 consecutive odd numbers whose sum will be 51 are  16, 17, 18.

The last statement the ratio of smoothies size to mangos used for Kim is same as the ratio of smoothie size to mangos used for Angela is correct.

What is ratio?

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Given:

Kim and her friends watched the server making smoothies.

The given table shows the number of mangos that were used for each of the different size of smoothies that the friends ordered.

From the given statements the last statement 'the ratio of smoothies size to mangos used for Kim is same as the ratio of smoothie size to mangos used for Angela.'

Because,

The ratio of smoothies size to mangos used for Kim is, 21/3 = 7 and

If A and B are independent events with given probabilities P(A) and P(B), then the probability of A intersecting B (P(A ∩ B)) is equal to the product of their individual probabilities. For example, if P(A) = 0.05 and P(B) = 0.65, then P(A ∩ B) = 0.0325.

The probability of two events A and B occurring together, P(A ∩ B), can be calculated by multiplying the individual probabilities of each event, P(A) and P(B). In this case,

P(A) = 0.4 and P(B) = 0.6, so P(A ∩ B) = 0.4 * 0.6 = 0.24

.The probability of event A occurring given that event B has already occurred, P(A | B), is equal to the probability of both events occurring together, P(A ∩ B), divided by the probability of event B occurring, P(B). In this case,

P(A ∩ B) = 0.24 and P(B) = 0.65, so P(A | B) = 0.24 / 0.65 = 0.0375

which can be rounded to 0.0325.These probabilities can be used to estimate the likelihood of certain events occurring together or given certain conditions. In this case, the probability of events A and B occurring together is 0.24 and the probability of event A occurring given that event B has already occurred is 0.0325.

A. P(A ∩ B) = P(A) * P(B)

When the ratio of each of the two quantities' values is equal, the two quantities are said to be proportionate. It comes in two varieties: direct and indirect. The ratio is more than one for direct relations whereas it is less than one for indirect relations.

The relationship provided in the issue can be expressed as,

W ∝ X

X now has a new value when it is increased by 50%:

X + 50% × X

⇒ X + 50/100 × X = 3X/2

Assume that X and W now have values of X1 and W1, respectively.

Consequently, they are related in the following ways:

W ∝ X

⇒ 3/2W ∝ 3/2X

⇒ 3/2W ∝ X₁

W's value is increased by 3/2W - W, which equals 1/2W.

A discontinuous function can be solved by analyzing the behavior of the function and its points of discontinuity. This can be done by finding the limits of the function at each point and then using the appropriate algebraic techniques to solve the equation.

Discontinuous functions are those that have gaps or sharp discontinuities in their graphs. In order to solve a discontinuous function, you must start by analyzing the behavior of the function and its points of discontinuity. This can be done by finding the limits of the function at each point and then using the appropriate algebraic techniques to solve the equation. This can involve factoring, manipulating equations, and other techniques to find the solution. Once the equation is identified, it can then be graphed to see the behavior of the function between the points of discontinuity. If necessary, the equation can then be further manipulated to satisfy the conditions of the discontinuous points. By approaching the problem in this manner, a discontinuous function can be effectively solved.

Yes, the equation 3x^2+2√5x has real roots. By expanding the equation, we get 3x^2+2x√5=0. We can use the quadratic formula to solve for x. First, we need to make the equation in the form of ax^2+bx+c=0. To do this, we complete the square. We divide both sides of the equation by 3, giving us x^2+2/3*√5x=0. Then, we add (2/3*√5/2)^2 to both sides, giving us x^2+2/3*√5x+(2/3*√5/2)^2= (2/3*√5/2)^2. Simplifying, we get x^2+2/3*√5x+5/12=0.

To find the interest rate, we can use the formula for simple interest:

I = P * r * t

Where I is the interest, P is the principal (the amount of money in the account), r is the interest rate, and t is the time (in years).

We know that I = $480, P = $2,000, and t = 2 years.

Plugging these values into the formula, we get:

$480 = $2,000 * r * 2

Dividing both sides by $2,000 * 2, we get:

r = $480 / $2,000 * 2

r = 0.12

Multiplicity is a mathematical concept related to the roots of a polynomial equation.

It is defined as the number of times a given root is repeated in the polynomial equation.

The formula for calculating the multiplicity of a root is :

Multiplicity = n-(degree of the polynomial equation)

where n is the order of the root and the degree of the polynomial equation is the highest exponent in the equation.

For example, if the polynomial equation is 3x^2 + 4x + 2 = 0 and the root is 2, then the multiplicity of the root is calculated as follows:

Multiplicity = n - (degree of the polynomial equation)

Multiplicity = 2 - 2

Multiplicity = 0

This means that the root 2 is not repeated in the polynomial equation and therefore has a multiplicity of 0.

In another example, if the polynomial equation is 4x^3 + x^2 + 6x + 12 = 0 and the root is 2, then the multiplicity of the root is calculated as follows:

Multiplicity = n - (degree of the polynomial equation)

Multiplicity = 2 - 3

This can be highlighted by counting the number of different elements, as in "the number of separate roots," if multiplicity is disregarded. However, multiplicity is always taken into account when a set (as opposed to a multiset) is established, therefore the word "different" is not necessary.
