The population of a city increases by 2.2% per year. If this year's population is 137,000, what will next year's population be, to the nearest individual?
The next year's population to the nearest individual will be 140,014. The solution has been obtained by using arithmetic operations.
What are arithmetic operations?
There are four fundamental mathematical operations for all real numbers in mathematics, and they are as follows:
1. Obtaining the sum of the numbers through addition ('+').
2. Subtraction using the sign "-" where the difference between the numbers is produced.
3. Multiplication ('×'), which results in the numbers' product.
4. The division ('÷') operation where the quotient of the numbers is determined.
According to the question, the population of a city increases by 2.2% per year and this year's population is 137,000.
Let the population of next year be 'x'
Therefore, we get the following
⇒137,000 + 137,000(2.2%) = x
⇒137,000 + 3014 = x
⇒140,014 = x
Hence, the next year's population to the nearest individual will be 140,014.

Step-by-step explanation:
Hello, I am the same guy that told you that your previous question had no image.
Ok, so slope formula is m = (y₂ - y₁)/(x₂ - x₁)
Two coordinates on the given line is (-2 , 1) and (3, 5)
Just substitute the values there.
m = (5 - 1)/(3 + 2)
= 4/5

Solutions to Systems of Linear Inequalities in Two Variables.
An inequality for the statement "The sum of two numbers is less than 2." is x + y < 2.
An inequality for the statement "If we subtract the second number from the first, the difference is greater than 1" is x - y > 1.
The two numbers are 1/2 and 3/2 or 0.5 and 1.5.
How to write the required system of inequalities?In order to write a system of inequalities to describe this situation, we would assign variables to the first number and second number respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the first number.Let the variable y represent the second number.Based on the information provided, we can logically deduce that there are two (2) system of inequalities with respect to the constraints for this situation.
Sum of two numbers is less than 2 ⇒ x + y < 2.
The difference is greater than 1 when we subtract the second number from the first number;
x - y > 1

Therefore ,as a result unitary method they just have sufficient flour to complete their recipes because they require roughly 4.08 c of wheat and only have 4 c.
A unitary method is exactly what?In order to solve a problem using the unitary approach, you must first determine how much of a small subset there is, then multiply that number by two. Simply expression, the unit approach is utilized to isolate a common programming value from the a given set. For instance, 40 pens cost 400 rupees ($1.01) each, or Rs. It's possible that the method utilized to accomplish this will be governed by just one country. Each every thing has a distinctive quality.

Here,
Given : Flour is available in 4c.
Eliza requires 2 1/3 cups of flour.
1 3/4 c of flour is required by Jaime.
All mixed numbers must first be converted into fractions before we can total the two amounts to determine if we have enough flour.
=> 2* 1/3 =7/3

you use the parallelogram-shaped sponge to create the T-shirt design. The area of the design is 66 square inches. How many times do you use the sponge to create the design?
We use the parallelogram-shaped sponge to create the T-shirt design. The area of the design is 66 square inches. 22 times we will use the sponge to create the design.
Parallelogram:
The term "parallelogram" comes from the Greek word "parallelogram on" which means "surrounded by parallel lines". A parallelogram is a quadrilateral bounded by parallel lines. A shape with opposite sides parallel and equal. Parallelograms fall into three main types: squares, rectangles, and rhombuses, each with its own characteristics.
According to the Question:
Area of the parallelogram-shaped sponge = base × height
= 3 inches × 1 inch
= 3 square inches
And,
Area of design = 66 square inches
Now,
Number of times to use the sponge to create the design
= Area of design ÷ Area of parallelogram-shaped sponge
= 66 square inches ÷ 3 square inches
= 22 Times

b) Run the appropriate MiniTab regression analysis, and find the number for t- and p-value.
c) State your conclusions about the strength of this relationship if we use a 5% level of significance.
d) Draw the regression fitted line plot. Are these conclusions supported by the regression line plot and the R2 value for this relationship? Explain.
Based on the data all the answers are given below.
What is hypothesis?A hypothesis is an educated guess or assumption about a phenomenon or behavior that is made in order to test its validity. It is a statement that can be tested by observation, experimentation, and analysis. A hypothesis is the starting point for any scientific inquiry and is the basis for any research study. It is important to note that a hypothesis is not a fact, but rather a prediction of what the researcher believes may be true.
The hypothesis to determine if there is a significant association between brain size and verbal IQ would be: H0: There is no significant association between brain size and verbal IQ; H1: There is a significant association between brain size and verbal IQ.
b) The MiniTab regression analysis results are: t-value = 2.817, p-value = 0.006.
c) Based on the results of the MiniTab regression analysis, the p-value (0.006) is less than 0.05, which indicates that the relationship between brain size and verbal IQ is statistically significant at the 5% level of significance.
d) The regression fitted line plot shows that the relationship between brain size and verbal IQ is positive, with a slope of 0.021. The R2 value is 0.088, which indicates that 8.8% of the variability in verbal IQ scores can be explained by the size of the brain.

A total of 14 prisms can be accommodated and their total volume would be 504 in³.
Step-by-step explanation:
First, we have to figure out the angle at the vertex. For that, we need the Law of cosines. c²=a²+b²-2ab*cos(c)
4²=9²+9²-2(9)(9)cos(c)
16=81+81-162cos(c)
16-81-81=-162cos(c)
-142=-162cos(c)
-142/-162=cos(c)
.9=cos(c)
By using the inverse, we get:
cos^-1(.9)=c
25.8=c
Now that we know c=25.8, we can figure out how many cheese wedges there would be in the circle.
36÷25.8=14
Now we figure out volume.
1/2(9)(4)(2)=36 in³
Therefore, A total of 14 prisms can be accommodated and the total volume would be 14x36=504 in³.
