The sum of the values is referred to as the operands, arguments, or inputs, while the result is referred to as the value, output, or result. Operations may require less than two inputs or more (including the case of zero input and infinitely many inputs). The answer will be 0.9+0.06+0.004= 0.964

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative integers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. The set that the values created are contained in is known as the codomain, while the set that the operation really produced is known as the codomain of definition, active codomain, image, or range. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

A scalar can be multiplied by a vector to create another vector (a process known as scalar multiplication), and two vectors can be combined to make a scalar quantity in an inner product operation. An operation may or may not have specific characteristics, such as being idempotent, associative, commutative, or anticommutative.

The discount of 45% saves the buyer the most money.

A dollar amount or a percentage deducted from an item's typical selling price is referred to as a discount.

let us check each discount one by one

a)Let the initial cost be 100

10% then 35%

=10% of 100

=10

New cost = 100 - 10 = 90

35% of 90 = 31.5

Final cost = 90-31.5 = 58.5

b)Let the initial cost be 100

20% then 25%

=25% of 100

=25

New cost = 100 - 25=75

25% of 75= 18.75

Final cost = 75-18.75 = 56.25

b)Let the initial cost be 100

45% discount

=45% of 100

=45

New cost = 100 - 45=55

Before waiting until after the holiday to make a purchase, make sure you actually need all of the things you intend to buy. A reduction in the price of a good or service is known as a discount.

Answer:

\(P(Dogs) = 0.2025\)

Step-by-step explanation:

Given

\(Proportion, p = 45\%\)

Required

Probability of two people having dog

First, we have to convert the given parameter to decimal

\(p = \frac{45}{100}\)

\(p = 0.45\)

Let P(Dogs) represent the required probability;

This is calculated as thus;

P(Dogs) = Probability of first person having a dog * Probability of second person having a dog

\(P(Dogs) = p * p\)

\(P(Dogs) = 0.45 * 0.45\)

\(P(Dogs) = 0.45^2\)

\(P(Dogs) = 0.2025\)

Hence, the probability of 2 people having a dog is \(P(Dogs) = 0.2025\)

        Make a plan:

We need to find the equation that represents the relationship between the total monthly bill (T), The Kilowatt Hours of Electricity used (k), and the Terms of Gas used (t).

T  =  0.25  *  k  +  0.97  *  t

1 - Write the Equation for the cost of Electricity:

        0.25 * k

2 - Write the Equation for the Cost of Gas:

       0.97 * t

3 - Combine the Equations to Represent the total Monthly Bill (T):

       T  =  0.25 * k + 0.97 * t

The stems are 0, 2, 3, 5, 6, 7, 8, 9. Therefore, option C is the correct answer.

Given that, here are the amounts of money (cents) in coins carried by 10 students in a statistics class: 50, 35, 0, 97, 76, 0, 0, 87, 23, 65.

We have to plot a stemplot for this data.

A stem and leaf plot also called a stem and leaf diagram is a way of organizing data into a form that makes it easy to observe the frequency of different types of values. It is a graph that shows numerical data arranged in order. Each data value is broken into a stem and a leaf.

A stem and leaf plot is represented in form of a special table where each first digit or digit of data value is split into a stem and the last digit of data in a leaf. This " | " symbol is used to show stem values and leaf values and it is called as stem and leaf plot key.

Now, 0, 0, 0, 23, 35, 50, 65, 76, 87, 97.

As the stem and leaf plot definition states,

2 I 3 ⇒ 2 on the stem and 3 on the leaf read as 23.

3 I 5 ⇒ 3 on the stem and 5 on the leaf read as 35.

5 I 0 ⇒ 5 on the stem and 0 on the leaf read as 50.

6 I 5 ⇒ 6 on the stem and 5 on the leaf read as 65.

7 I 6 ⇒ 7 on the stem and 6 on the leaf read as 76.

8 I 7 ⇒ 8 on the stem and 7 on the leaf read as 87.

9 I 7 ⇒ 9 on the stem and 7 on the leaf read as 97.

The stems are 0, 2, 3, 5, 6, 7, 8, 9. Therefore, option C is the correct answer.

The factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).

To determine the factors of the polynomial x^3 - 12x^2 - 2x + 24 by grouping, we can follow these steps:

Step 1: Group the terms in pairs. In this case, we can pair the first two terms and the last two terms:

(x^3 - 12x^2) + (-2x + 24)

Step 2: Factor out the greatest common factor from each pair. From the first pair, we can factor out x^2, and from the second pair, we can factor out -2:

x^2(x - 12) - 2(x - 12)

Step 3: Notice that we now have a common binomial factor of (x - 12) in both terms. Factor out this common binomial factor:

(x - 12)(x^2 - 2)

Therefore, the factored form of the polynomial x^3 - 12x^2 - 2x + 24 by grouping is (x - 12)(x^2 - 2).

The reflection of the figure over y = -2x - 1 is attached accordingly.

A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a fixed point set; this set is known as the axis or plane of reflection.

Because the line of reflection has a slope of -1/2, each image point will be on a line with a slope of 2 that passes through the associated pre-image point.

It might be simplest to count the grid squares between the pre-image point and the line, then from the line to the image point's location. Those measurements will be the same.

Step-by-step explanation:

The difference between the number of points and the number of polygons formed by the chords inside the circle is: Number of points of intersection has two end point while number of polygons formed by the chords inside the circle has the same area.

Given;
Circle chords=1500

Since the circle has 1500 chords which means that the number of chords is 1500, now we have to multiply the number of chords by 2 end point so as to determine the number of end points

Number of chords=1500

Number of end points=1500×2

Number of end points=3,000

Therefore based on the above we can see that number of points of intersection has two end point while on the other hand number of polygons formed by the chords inside the circle has the same area.

Whwn the line of sight from the park ranger station, P, to the lifeguard chair, L, the length of PL is 0.76 miles.

It should be noted that since the line of sight from the park ranger station, P, to the lifeguard chair, L, on the beach of a lake is perpendicular to the path joining the campground, C, and the first aid station, F, then the path from the park ranger station to the lifeguard chair is the hypotenuse of a right triangle with legs of 0.35 miles and 0.65 miles.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs. Therefore, the length of PL is equal to:
