The better buy is given by the following brand:

Brand A.

The better buy is obtained applying the proportions in the context of the problem.

A proportion is applied as the cost per ounce is given dividing the total cost by the number of ounces.

Then the better buy is given by the option with the lowest cost per ounce.

The cost per ounce for each brand is given as follows:

$8 per ounce is a lesser cost than $9.3 per ounce, hence the better buy is given by Brand A.

Using a system of linear equation, the cost of each shirt and pant is $9 and $11 respectively.

A system of linear equations is a collection of one or more linear equations that contain two or more variables. The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system.

A linear equation is an equation that can be written in the form of ax+by=c, where x and y are variables, and a, b, and c are coefficients.

In this problem, we need to define our variables and the solve the equations.

Let;

x + 2y = 31 ...eq(i)

3x + y = 38 ...eq(ii)

Solving both equations

x = 9, y = 11

To find the height of the person, we can set up a proportion using the given information.

Let's denote the height of the person as 'x'.

The proportion can be set up as follows:

(Height of building) / (Shadow of building) = (Height of person) / (Shadow of person)

Plugging in the given values:

100 ft / 25 ft = x / 1.5 ft

To solve for 'x', we can cross multiply:

(100 ft) * (1.5 ft) = (25 ft) * x

150 ft = 25 ft * x

Dividing both sides of the equation by 25 ft:

x = 150 ft / 25 ft

x = 6 ft

Therefore, the person is 6 feet tall.

In conclusion, the height of the person is 6 feet, based on the given proportions and calculations.

The height of the building is 100ft and the building cast a shadow of 25ft.

A person cast a shadow of 25ft so by using the proportion comparison the height of a person is 6ft.

Given that the height of a building is 100ft and the length of its shadow is 25ft. Let's assume that the height of a person is x whose length of the shadow is 1.5ft.

The ratio of the building's height to its shadow length is the same as the person's height to their shadow length.

Therefore, by using the proportion comparison we get,

(Height of building) / (Shadow of the building) = (Height of person) / (Shadow of person)

100/25= x/1.5

4= x/1.5

Multiplying both sides by 1.5 we obtain,

1.5×4= 1.5× (x/1.5)

x =1.5×4

x=6.0

Hence, the height of a person is 6ft if they cast a shadow of 1.5ft.

The time for the investment if, A (t)  = \(850 (1.0623)^t\) Is 11.4 years.

The entire amount repaid at the conclusion of the borrowing period is indicated by the letter (A). A = P(1 + RT) is another way to express the simple interest total amount formula. Here, A stands for the total sum after the specified time.

Given:

The amount of money in an investment is modeled by the function,

A (t)  = \(850 (1.0623)^t\)

The number of years can also be represented by n,

A (n) = 850 (1.0623)ⁿ

If the amount is doubled then,

A (n) = 1700 = 850 (1.0623)ⁿ

2 = (1.0623)ⁿ

Take log both sides, the above expression can be written as,

n = log 2 / log (1.0623)

n = 0.30 / 0.0262

n = 11.429 or 11.4 years

Thus, the time t will be 11.4 years.

Answer:

They will be parallel.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Translation is the movement of a point up, down, left or right. Rotation is the turning of a point about a fixed point.

If two parallel lines a and b are rotated 90° in the same direction, they would still be parallel. If they are then translated to the right by the same number of units, they would still remain parallel to each other.

The corrected statement should look like this:
```java
int[] hours = {8, 12, 16};
```

It looks like you are trying to create an integer array in Java called "hours" and initialize it with the values 8, 12, and 16. The given statement has incorrect syntax.
Declare the integer array using "int[]" followed by the variable name "hours".

This tells the Java compiler that you want to create an array of integers called "hours".
Use the assignment operator "=" to assign values to the array.
Enclose the values you want to assign to the array within curly braces "{" and "}" and separate each value with a comma.
The corrected statement should look like this:
```java
int[] hours = {8, 12, 16};
```
Now, the "hours" integer array is initialized correctly with the given values.

The syntax for declaring and initializing an integer array in Java is:

```java
data Type[] array

Name = {value1, value2, value3, ...};
```
In this case, "data Type" is "int", "array

Name" is "hours", and the values are 8, 12, and 16.
Remember to keep your code clean and concise to avoid syntax errors and make it easier for others to understand.

Answer:

x=-1 y=5

Step-by-step explanation:

x+2y=9

3x+y=2

If we  multiply the second equation by -2 we get

-6x-2y=-4

then if we add this to x+2y=9 we get

-5x=5

if we multiply both sides by -1 we get

5x=-5

divide both sides by 5 we get

x=-1

multiplying the first equation by -3 we get

-3x-6y=-27

adding this to the original second equation we get

-5y=-25

multiply both sides by -1

5y=25

divide both sides by 5

The volume of the solid the region defined by the given curves must be rotated about the x-axis is V = \(\frac{384\pi }{5}\).

Given that,

The region defined by the given curves must be rotated about the x-axis to determine the solid's volume, which is y =6 -x², y =2.

We know that,

Take the equation of the curves about the x- axis

y =6 -x², y =2.

Substitute y = 2 in equation y = 6 - x²

2 = 6 - x²

-x² = 2-6

x² = 4

Taking square root on both sides

x = ±2

Now, volume formula is define by using washer method

V =  \(\pi \int\limits^a_b {[f(x)]^2 - [g(x)]^2} \, dx\)

V = \(\pi \int\limits^2_{-2} {[6-x^2]^2 - [2]^2} \, dx\)

V = \(\pi \int\limits^2_{-2} {(36 + x^4 - 12x^2 - 4}) \, dx\)

V = \(\pi \int\limits^2_{-2} {(x^4 - 12x^2 - 32)} \, dx\)

V = \(\pi( [\frac{x^5}{5}] - 12\times\frac{x^3}{3} -32x)^2_{-2}\)

V = \(\pi[( [\frac{2^5}{5}] - 12\times\frac{2^3}{3} -32(2))-([\frac{-2^5}{5}] - 12\times\frac{-2^3}{3} -32(-2))]\)

V = \(\pi[( [\frac{32}{5}] - 4 \times 8 -64)-( [\frac{-32}{5}] - 4\times(-8) +64)]\)

V = \(\pi[( [\frac{32}{5}] - 32 -64)-( [\frac{-32}{5}] +32 +64)]\)

V = \(\pi( [\frac{384}{5}] )\)

V = \(\frac{384\pi }{5}\)

Answer:

a = -9

Step-by-step explanation:

Starting with:

2/3a = -15 - a

Solve for 'a' by isolating the variable:

2/3a = -15 - a

On the right-hand side of the equal sign, make 'a' have a common denominator of 3 to make the simplifying easier:

2/3a = -15 - 3/3a

Add 3a/3 to both sides:

5/3a = -15

Divide both sides by 5/3, or multiply by its reciprocal (3/5)

5/3a(3/5) = -15(3/5)

a = -9

Answer:

Explained below.

Step-by-step explanation:

The z-test statistic is given as follows:

\(Z=\frac{\bar X-\mu}{\sigma/\sqrt{n}}\)

Here,

\(\bar X=\text{Sample Mean}\\\\\mu=\text{Population Mean}\\\\\sigma=\text{Population standard deviation}\\\\n=\text{Sample size}\)

The p-value is well-defined as per the probability, [under the null-hypothesis (H₀)], of attaining a result equivalent to or greater than what was the truly observed value of the test statistic.

(i)

The difference between the sample mean and the original population mean are directly proportional to the z-test statistic.

So, increasing the  difference between \(\bar X\) and \(\mu\) will lead to an increase in the z-score.

And as the Z-score increases the p-value of the test decreases.

Thus, the complete statement is:

"Increasing the difference between the sample mean and the original population mean will result in an increase in the absolute value of z, and a decrease in the probability of obtaining a sample with that mean."

(ii)

The population standard deviation is inversely proportional to the z-test statistic.

So, increasing the population standard deviation will lead to a decrease in the z-score.

And as the Z-score decreases the p-value of the test increases.

Thus, the complete statement is:

"Increasing the population standard deviation will result in a decrease in the absolute value of z, and an increase in the probability of obtaining a sample with that mean"

(iii)

The number of scores in the sample is directly proportional to the z-test statistic.

So, increasing the number of scores in the sample will lead to an increase in the z-score.

And as the Z-score increases the p-value of the test decreases.

Thus, the complete statement is:

"Increasing the number of scores in the sample will result in an increase in the absolute value of z, and an decrease in the probability of obtaining a sample with that mean."
