The kind of sequence shown 2, -1, -4, -7, -10, is definitely an arithmetic sequence.

In mathematics, a sequence is a collection of numbers or items that have been organised in a certain order in accordance with a set of rules. These sequences, which might be endless or finite, are useful for simulating a variety of real-world processes. In addition to its practical uses, sequences are an essential mathematical notion that allows us to analyse patterns and relationships between numbers. We may edit and examine sequences to better understand their characteristics and behaviour by applying mathematical operations. Sequences are frequently used to investigate patterns and relationships between numbers, as well as to solve problems in a variety of mathematical disciplines such as algebra, calculus, and geometry. Arithmetic sequences, geometric sequences, recursive sequence are a few examples of frequent sequence types.

How to solve?

In an arithmetic sequence, the difference between any two consecutive terms is constant.

In the given sequence, the difference between any two consecutive terms is -3. i.e.,

d = -10 - (-7) = -7 -(-4) = -4 - (-1) = -1 - (2) = -3

Therefore, the sequence is an arithmetic sequence.

The rate of change of the distance with respect to time that the box submarine traveled is 11 feet per second

A rate of change describes how one quantity changes in relation to another quantity.

Mathematically, it is defined as the change in one quantity divided by the change in the other quantity.

In this case, we have:

rate of change = change in distance / change in time

Use the data in the table:

rate of change = 545-380/15-0

rate of change = 165/15 = 11

Note: You can pick any 2 data points for the calculation

The probability distribution that she or he is on duty on Saturday or Sunday will be 0.7

What is probability distribution ?

A frequency distribution that has been idealised is a probability distribution.

An individual sample or dataset is described by its frequency distribution. It's the number of times in the dataset that each potential value of a variable appears.

The probability of occurrence of a value determines how frequently it appears in a sample. Probability is a value between 0 and 1 that indicates the likelihood that something will happen:

A value will occur more frequently in a sample the higher its likelihood.

The probability of a value is more particularly the relative frequency in an indefinitely large sample.

Probability distributions are theoretical since it is not feasible to obtain infinitely large samples in practise.

Let the people work on Sunday = sun = 4

Let the people work on Saturday = sat = 3

total no. of doctors are 10

so the probability distribution of people work on either Sunday or Saturday will be :

The size of the letters appear on the retina is 0.00289 cm

Given data:

To determine the size of the letters on the retina, use the concept of angular size and the relationship between object size, distance, and angular size.

Angular size is the measure of the angle subtended by an object as seen from a particular point, in this case, the eye.

Angular size = Object size / Distance

Object size = 1.0 cm

Distance = 6 meters

Angular size = 1.0 cm / 6 meters

To convert the distance to centimeters, multiply by 100:

Angular size = 1.0 cm / (6 meters * 100 cm/meter)

Angular size = 1.0 cm / 600 cm

Angular size = 0.0017 radians

The angular size of the letters is 0.0017 radians.

Now, to determine the size of the letters on the retina, calculate the linear size on the retina using the angular size and the distance from the lens to the retina.

Linear size on retina = Angular size * Distance from lens to retina

Angular size = 0.0017 radians

Distance from lens to retina = 1.7 cm

Linear size on retina = 0.0017 radians * 1.7 cm

Linear size on retina ≈ 0.00289 cm

Hence, the letters appear to be approximately 0.00289 cm in size on the retina.

Step-by-step explanation:

△X'Y'Z' is transformed form △XYZ. If △XYZ rotated 90 degrees counterclockwise about the origin, then YZ ⊥ Y'Z'. Hence option B is the correct option.

What is transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given that,

△XYZ is rotated 90 degrees counterclockwise about the origin to form △X'Y'Z'.

Each side of △XYZ is rotated 90 degrees counterclockwise.

Then the angle between corresponding sides of △XYZ and △X'Y'Z' are 90 degrees.

Therefore

Answer:

x = -3

y = -4

Step-by-step explanation:

2x - 5y = 14 ⇒ ( 1 )

y = 3x + 5 ⇒ ( 2 )

First, let us find the value of x.

For that let us use equation ( 1 ) and replace y with (3x + 5 ).

2x - 5y = 14

2x - 5 ( 3x + 5 ) = 14

Solve the brackets.

2x - 15x - 25 = 14

Combine like terms.

-13x - 25 = 14

Add 25 to both sides.

-13x = 14 + 25

- 13x = 39

Divide both sides by -13.

x = -3

Let us find the value of y.

For that, use equation (2) and replace x with (-3).

y = 3x + 5

y = 3 × -3 + 5

y = - 9 + 5

y = -4

In a proportional relationship, every minute has the same charge.

Answer: A

Step-by-step explanation: To solve this problem, we can set up a system of equations to represent the information given in the problem. Let x represent the cost of a plate of spring rolls, y represent the cost of a plate of chicken tenders, and z represent the cost of a plate of pretzel dippers.

The first group spent $23 on 2 plates of chicken tenders and 1 plate of pretzel dippers, so the equation for this group is:

2y + z = $23

The second group spent $30.75 to buy 3 plates of spring rolls and 1 plate of chicken tenders, so the equation for this group is:

3x + y = $30.75

The third group spent $22.25 on one of each appetizer, so the equation for this group is:

x + y + z = $22.25

Now that we have three equations, we can use algebraic techniques to solve for the value of x, which represents the cost of a plate of spring rolls.

First, we can solve the second equation for y:

y = $30.75 - 3x

Substituting this expression for y into the first equation, we get:

2($30.75 - 3x) + z = $23

Solving for x, we find that x = $7.75.

Therefore, the cost of a plate of spring rolls is $7.75, so the answer is A.

Following is the geometric progression of Nelson's debt after each month: (E) 950,967.1, 984.51, 1002.23, 1020.27

A geometric progression sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

So, in this issue, the interest rate is as follows: 1.8%.

The debt will therefore be equal to the debt from the previous month multiplied by 100 + 1.8 = 101.8% = 1.018 each month, and the common ratio is as follows: 1.018.

In light of this, the terms of the series are as follows:

2nd term: 950 x 1.018 = $967.1

3rd term: 967.1 x 1.018 = $984.51

4th term: 984.51 x 1.018 = $1002.23

5th term: 1002.23 x 1.018 = $1020.27

Therefore, the following is the geometric progression of Nelson's debt after each month: (E) 950,967.1, 984.51, 1002.23, 1020.27

m = slope

b = y-intercept

You are given the y-intercept from the point (0,2). When x = 0, y = 1

You can then see from the Eq: y = mx + b  

that b = 1

By dividing the change in y by the change in x, or "rise over run," one may get the slope, m.
