The expressions that are equivalent to the expression y + y + y + 3z are 3y + 3z and 3(y + z)

From the question, we have the following parameters that can be used in our computation:

y + y + y + 3z

To start with, expressions that are equivalent are expressions that have equal values when evaluated

Using the above as a guide, we have the following:

Evaluate the like terms in y + y + y + 3z

So, we have the following representation

y + y + y + 3z = 3y + 3z

Factor out 3 from the expression

So, we have the following representation

y + y + y + 3z = 3(y + z)

Hence, the equivalent expressions of y + y + y + 3z are 3y + 3z and 3(y + z)

The interest rate, to the nearest hundredth of a percent, that would be required in order for Mohal to end up with $1,110 would be = 4.2%

The interest rate of an investment is defined as the rate at which an individual receives stipulated amount of money for a period of time over the investment made.

The amount for investment (P) = $830

The time for investment(T) = 8 years

The simple interest yield(SI) = $1,110 -830 = 280

The rate(R) = x%

using the formula;

Simple interest = P×T×R/100

Make R the subject of formula;

R= SI ×100/P×T

R= 280×100/830×8

What is probability distribution?

The probabilities of any random occurrence are determined by the probability distribution. It is sometimes described as a collection of potential results from any random experiment depending on the underlying sample space. A set of real numbers, a set of vectors, or a set of any other things might make up these settings. It is a component of statistics and probability.

The outcome of an experiment whose results cannot be anticipated is known as a random experiment. Imagine that we can't foresee whether a coin will land on its head or its tail when we throw one. An outcome is a potential outcome of a random experiment. The collection of results is known as a sample point.

X ~ Bin ( n , p)

Where n = 12 , p = 0.28

Binomial probability distribution is

P(X) = nCx * px * ( 1 - p)n-x .

Then the  operator asks the answering person whether she has time to answer some questions.

Y is the number of calls made until the first person replies that she is willing to answer the questions

There is no independent variable the affect the value of the Y. here the number of trial are not fixed, so there wont be any binomial distribution

The addition of the given system of equations is 10x = 10.

What is system of equations?

A set of one or more equations involving numerous variables is referred to as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations, or the points where the components of these equations intersect.

Consider the given system of equations

3x - y = -5         ..(1)

7x + y = 15        ..(2)

We have to find the addition of this equations.

Add equation (1) and equation (2).

b) The marginal relative frequency of all customers who like hamburgers is of: 0.6537.

c) The lowest joint frequency is not liking neither of hamburgers or burritos.

The relative frequency is obtained as the division of the number of desired outcomes by the number of total outcomes.

The percentage is calculated as the multiplication of the relative frequency by 100%.

From the table given by the image at the end of the answer, the total number of people in the survey is of:

Answer: Yes, Montoya's square root will equal the number of blocks in one side of the graph-paper square.

Step-by-step explanation: The square root of a number is the number that, when multiplied by itself, produces the original number. For example, the square root of 16 is 4, because 4 * 4 = 16.

If Montoya has cut out a perfectly square section of graph paper, the number of blocks in the square will be the same as the number of blocks in one side of the square multiplied by the number of blocks in the other side of the square. In other words, the number of blocks in the square will be the square of the number of blocks in one side of the square.

Therefore, when Montoya takes the square root of the number of blocks in the square, she will get the number of blocks in one side of the square.

For example, if Montoya's square has 4 blocks on each side, the number of blocks in the square will be 4 * 4 = 16, and the square root of 16 will be 4, which is the number of blocks in one side of the square.

A recurrence relation is an equation in mathematics that states that the nth term of a series of numbers is equal to some combination of the terms that came before it.

A recurrence relation is an equation in mathematics that states that the nth term of a series of numbers is equal to some combination of the terms that came before it.

For a parameter k that is independent of n, only k preceding terms of the sequence frequently occur in the equation; this number k is known as the order of the relation.

The rest of the series can be determined by continually using the equation if the values of the first  integers in the sequence have been provided.

The nth term in linear recurrences is equivalent to a linear function of the k prior terms. The Fibonacci numbers' recurrence is a well-known example.

Hence, A recurrence relation is an equation in mathematics that states that the nth term of a series of numbers is equal to some combination of the terms that came before it.

We can conclude that the width of the rectangular ground is 19ft.

A quadrilateral with all of its angles equal, or right angles, is a rectangle.

In addition to having all equal angles, a square also has all equal sides. Therefore, a special case of a square is a rectangle.

To put it another way, a rectangle can also be a square.

So, we know that:

The perimeter of the rectangular ground is 90ft.

The length of the rectangular ground is 26ft.

Now, the width will be:

Perimeter of rectangle formula: P =  2(l+w)

Now, put the values and substitute as follows:

P =  2(l+w)

90 =  2(26+w)

90 = 52 + 2w

2w = 90 - 52

2w = 38

w = 38/2

w = 19ft

Therefore, we can conclude that the width of the rectangular ground is 19ft.

Answer:  -45x + 111 or -3(15x-37)

Step-by-step explanation:

Instead of :6 (8-3x )− 3 (9x−1 )+ 60

54 - 18x = −27x − 3 + 60

54 - 18x = −27x + 57

-18x = -27x + 3

9x = 3

x= 1/3

Corrected :

6 (8-3x )− 3 (9x−1 )+ 60

First Simplify : 54 - 18x -27x - 3 + 60

Combine Like terms Like 54, - 3, and 60 : 111 - 18x -27x

Combine Like Terms Like -18x and -27x : 111 -45x

Rearrange It So The Variable Is First : -45x + 111

So, the answer is -45x + 111 or if you want you can still simplify it by finding the common factor which you will get -3(15x-37)

Corrections : The friend is wrong because he turned the equation into an inequality instead of simplifying it. He turned the equation into an inequality by adding an equal sign in the middle then he tried to solve it like how you solve inequalities.

Step-by-step explanation:

You want to know which of these equations is linear.

For the purpose here, we will define a linear equation as one that graphs as a straight line. (Other definitions may give different answers.)

In general, a linear equation will have a highest degree of 1. (It may be 0.)

The equation of choice (b) has degree 2, so is not a linear equation.

The attached graph shows the only equation that is not linear is choice (b).

In some branches of mathematics, an equation of the form y = mx+b is not a linear equation. In basic algebra, that is the model of a linear equation, for any values of m and b.
