If every 2 inches of Yolanda's drawing represents 3 feet of the actual wall, we can use the scale factor to convert the dimensions of the drawing to the dimensions of the actual wall.

Since we are dealing with area, we need to square the scale factor.

2 inches : 3 feet

(2 inches / 3 feet)^2 = (2/36)² = 1/324

This means that every square inch of Yolanda's drawing represents 1/324 square feet of the actual wall.

If the area of the mural in Yolanda's drawing is A square inches, then the area of the actual mural is:

A (square inches) x (1/324) (square feet per square inch) = A/324 square feet

Therefore, to find the area of the actual mural in square feet, we need to first find the area of the mural in Yolanda's drawing and then divide by 324.

If the area of the mural in Yolanda's drawing is, for example, 500 square inches, then the area of the actual mural is:

500 (square inches) / 324 = 1.54 square feet (rounded to two decimal places)

Therefore, the area of the actual mural is 1.54 square feet.

Option A is the answer. The system of inequalities that can be used to determine the number of gallons of chocolate ice cream and the number of 5-quart containers of vanilla ice cream that Krystal can buy for this dinner is:

8c + 6v ≤ 70

8c + 6v ≤ 7016c + 20v ≥ 150

The cost of c gallons of chocolate ice cream is $8c, and the cost of v containers of vanilla ice cream is $6v. Krystal wants to spend no more than $70 on ice cream, so the inequality for the total cost of ice cream is:

8c + 6v ≤ 70

Krystal needs at least 150 servings of ice cream, and each gallon of chocolate ice cream provides 16 servings, while each container of vanilla ice cream provides 20 servings. The inequality for the total number of servings of ice cream is:

16c + 20v ≥ 150

Therefore, the system of inequalities that can be used to determine the number of gallons of chocolate ice cream and the number of 5-quart containers of vanilla ice cream that Krystal can buy for this dinner is:

When a new student joined the classroom with a height of 51 inches, the statistics that were calculated will be

impacted in the following ways:

Mean: The mean is calculated by adding up all the heights and then dividing the total by the number of heights. Since

the new student is much taller than the rest of the class, the addition of 51 to the data set will increase the sum of the

data set by a significant amount. This will cause the mean to increase.

Median: The median is the middle number when the data set is ordered from lowest to highest. Since the data set has

an odd number of values, the median is 40. When a new student joins the class with a height of 51 inches, this will

cause the median to increase to 40.5.

Mode: The mode is the number that appears most often in the data set. Since the mode of the given data is 40, adding

Answer:Radius = 21

Step-by-step explanation:

Volume of a sphere = 4/3 * pie * radius^3

12,348 pie = 4/3 * pie  radius ^3

12,348 = 4/3 * radius^3

(12,348 * 3)/ 4 = radius^3

9261 = radius^3

radius = 21

The association on the line is a negative linear assosciation and other solutions are shown below

To find the slope of the line passing through the given points, we use the slope formula

slope = (change in y) / (change in x)

Let's use the points (0, 90) and (8, 40) to find the slope:

slope = (40 - 90) / (8 - 0) = -50 / 8 = -6.25

The y-intercept is 90 i,e, when x = 0

The equation is represented as

y = mx + c

Where

m = slope and c = y when x = 0

The elimination approach can be used to resolve the system of equations below.

How does elimination work?

The elimination method is a method for algebraically resolving systems of linear equations. Using fundamental arithmetic operations, we can eliminate any one of the variables in the elimination technique, and then we can simplify the equation to determine the value of the remaining variable1.

The elimination procedure involves the following steps:

1. Choose one variable to leave out.

2. In order to make the coefficients of that variable opposite in sign, multiply or divide both equations by a non-zero constant.

3. Adjust the resulting equations such that the selected variable is removed.

4. Simplify and ascertain the other variable's value.

According to the question:

2x - 3y = 6

4x - 6y = 11

The result of multiplying the first equation by two is:

4x - 6y = 12

We can now take the second equation out of this equation:

4x - 6y = 12

(4x - 6y = 11)

0x + 0y = 1

For any value of x and y, this equation cannot be true.

The manufacturer B is calculated to produce, on the average, the fewest number of defective rivets amongst all the manufacturers.

To determine which manufacturer will produce, on average, the fewest number of defective rivets, we need to calculate the proportion of defective rivets for each manufacturer.

Let X be the breaking strength of a rivet from manufacturer A, and let Y be the breaking strength of a rivet from manufacturer B. Then:

P(X < 10000) = P((X - μ_A) / σ_A < (10000 - μ_A) / σ_A) = P(Z_A < -2.5) ≈ 0.0062

where Z_A is a standard normal random variable, and we use the given values μ_A = 14000 psi and σ_A = 2000 psi.

Similarly:

P(Y < 10000) = P(Z_B < -3) ≈ 0.0013

where Z_B is a standard normal random variable, and we use the given values μ_B = 13000 psi and σ_B = 1000 psi.

Therefore, the proportion of defective rivets for manufacturer A is approximately 0.0062, and the proportion of defective rivets for manufacturer B is approximately 0.0013.

Since manufacturer B has a lower proportion of defective rivets, on average, it will produce fewer defective rivets than manufacturer A. So the manufacturer that will produce, on average, the fewest number of defective rivets is manufacturer B.

Similarly, let the letters "A, B, J, and N" denote the song that is liked by only Amy, only Beth, only Jo, and none of them, respectively.

We know that there is at least 1 AB, BJ, and AJ, there must be 3 songs out of 4 songs which Amy, Beth, and Jo listened to.

The fourth song can be of any type : N, A, B, J, AB, BJ, and AJ (there is no ABJ because "no-song" is liked by all three),

So, we must find the number of ways to rearrange AB, BJ, AJ and a song from the set {N, A, B, J, AB, BJ, AJ}.

⇒ Case 1: Fourth song choices = N, A, B, J

All the four of choices for fourth song are different from the first 3 songs.

⇒ Number of ways to rearrange = 4! × 4 choices = 96.

⇒ Case 2: Fourth song choices = AB, BJ, AJ

All 3 of choices for fourth song repeat in the first three songs.

So, Number of ways to rearrange = (4!/2!) × 3 = 36,

Price Index is a effective method of comparing relative change in the price of a quantity with respect to its price in a reference year. This year which we use as a reference is called the base year and price index is ratio of the price of a product in a year to its price in the base year ( expressed in percentage ).

The cost to fill a gas tank in 1995 = $15

Price index in 1995 = 100.8%

price index in 2015 = 210.0%

In this case we want to determine the cost to fill a gas tank in 2015. Let the required cost value be x dolars. Using the formula, price index in 1995/price index in 2015 = reference value/ value in 2015

The percentage increase/decrease of the DJIA over the week is a decrease of 6.53%.

Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%".

A decreased percentage refers to the amount or rate by which a quantity or value has decreased from its original or initial value, expressed as a percentage of the original value.

According to given information:

To find the percentage increase/decrease of the DJIA over the week, we need to calculate the overall change in the index and express it as a percentage of the initial value.

Let's assume that the DJIA started the week at a value of 100. Then, the following changes would occur:

On Monday, it went down by 3.2%, so its value decreased to 96.8.

On Tuesday, it went up by 11.2%, so its value increased by 11.2% of 96.8, or 10.82, to reach 107.62.

On Wednesday, it went up by 0.7%, so its value increased by 0.7% of 107.62, or 0.75, to reach 108.37.

On Thursday, it went down by 4.8%, so its value decreased by 4.8% of 108.37, or 5.20, to reach 103.17.

On Friday, it went down by 9.4%, so its value decreased by 9.4% of 103.17, or 9.70, to reach 93.47.

Therefore, over the week, the DJIA decreased by 6.53% (from 100 to 93.47).

Rounding this to the nearest hundredth of a percentage, we get a decrease of 6.53%.

So, the percentage increase/decrease of the DJIA over the week is a decrease of 6.53%.

We use the product rule and the chain rule to find the derivative of y = e^4x sin 4x.

y = e^4x sin 4x

y' = (e^4x)(4sin 4x + cos 4x(4))

y' = 4e^4x(sin 4x + cos 4x)

Therefore, the first derivative of y=e^4x sin 4x is y' = 4e^4x(sin 4x + cos 4x).

Interpretation: The first derivative gives the instantaneous rate of change of the function at each point. In this case, the derivative represents the rate at which the amount of medicine remaining in a person's bloodstream changes with respect to time x. The function has a maximum or minimum when the first derivative is equal to zero.

The total volume of the plant stand is given by the sum of these expressions: (x+1)³ + (x+1) * (x+1) * (x-1) + (2x+3) * (2x-2) * (x+1)

Volume refers to the amount of space occupied by an object or substance. It is typically measured in cubic units (such as cubic centimeters, cubic inches, or liters) and is used to describe the size or capacity of an object or container. Volume can also refer to the loudness or intensity of a sound. In physics, volume is an important measurement in determining the properties and behavior of gases, liquids, and solids.

Here,

Let's calculate the volume of each section based on the given sides.

Cube with sides x+1:

The formula for the volume of a cube is V = side³, where side is the length of one of its sides. In this case, the side length of the cube is x+1, so the volume of this section would be:

V1 = (x+1)³

Cuboid with sides x+1, x+1, and x-1:

The formula for the volume of a cuboid is V = length * width * height. In this case, the length would be x+1, the width would be x+1, and the height would be x-1. So the volume of this section would be:

V2 = (x+1) * (x+1) * (x-1)

Cuboid with sides 2x+3, 2x-2, and x+1:

Similarly, using the formula for the volume of a cuboid, the volume of this section would be:

V3 = (2x+3) * (2x-2) * (x+1)

Now, to find the total volume of the plant stand, we can add up the volumes of all three sections:

Total volume = V1 + V2 + V3

= (x+1)³ + (x+1) * (x+1) * (x-1) + (2x+3) * (2x-2) * (x+1)

The measure of angle y is 32°.

To find the measure of angle y, follow these steps:
1. Since the exterior angle to angle x is w, and w measures 100°, we can use the fact that the sum of an interior angle and its corresponding exterior angle is 180°.

So, angle x = 180° - 100° = 80°.
2. Now we know that a triangle has angles x, y, and z.

The sum of angles in a triangle is always 180°.

We have x = 80° and z = 68°,

so we can find angle y as follows:

y = 180° - (80° + 68°)
