The equation for the proportion, p, of consumers who shop with coupons is: p = C/N where C is the number of consumers who use coupons and N is the total number of consumers asked.

An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.

Here,

This equation represents the ratio of the number of consumers who use coupons to the total number of consumers. It is commonly used in statistics and market research to measure the prevalence of a certain behavior or preference among a population. By calculating the proportion of consumers who use coupons, businesses can make informed decisions about their pricing strategies, promotions, and advertising campaigns.

Answer:

Step-by-step explanation:

The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

To solve this problem, we can use the concept of radioactive decay and the decay factor. Here's how we can calculate the required volume to correct the dose:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = Initial activity * Decay factor

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = Initial activity - 20 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = Remaining activity * Decay factor

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = Desired activity at 9:30 / Remaining activity at 9:30 * Volume at 9:30

Calculate the remaining volume at 9:30:

Remaining volume = Volume at 8 am - Volume withdrawn - Volume accidentally discharged

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume

Let's perform the calculations step by step:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = 180 mCi * 0.841 = 151.38 mCi

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = 180 mCi - 20 mCi = 160 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = 160 mCi * 0.841 = 134.56 mCi

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = (Desired activity at 9:30 / Remaining activity at 9:30) * Volume at 9:30

Volume at 9:30 = Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Volume needed = (20 mCi / 134.56 mCi) * 15 ml = 2.236 ml

Calculate the remaining volume at 9:30:

Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume = 2.236 ml - 15 ml = -12.764 ml

Since the calculated volume to be added is negative, it means that no additional volume is required. The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

The standard deviation of a sample is the square root of the variance

The sample is given as: 11, 6, 10, 6, and 7

Start by calculating the mean

\(\bar x = \frac{\sum x}{n}\)

So, we have:

\(\bar x = \frac{11+ 6+ 10+ 6+ 7}{5}\)

\(\bar x = 8\)

The variance is then calculated as:

\(\sigma^2 = \frac{\sum(x - \bar x)^2}{n -1}\)

This gives

\(\sigma^2 = \frac{(11 - 8)^2 + (6 - 8)^2 + (10 - 8)^2 + (6 - 8)^2+(7 - 8)^2}{5 -1}\)

\(\sigma^2 = 5.5\)

Hence, the variance is 5.5

In (a), we have:

\(\sigma^2 = 5.5\)

Take the square roots of both sides

\(\sqrt{\sigma^2} = \sqrt{5.5\)

\(\sigma = 2.35\)

Hence, the standard deviation is 2.35

Here are the completed tables:

Coffee (ounces)     4        8          12       16

Cream (ounces)     3/8    3/32     1 1/8     1 1/2

Yards            4     8.7    13.6      25

Seconds       6.4   10      15.6      40

Ratio is a concept that is used in mathematics to compare two or more numbers together. It shows the relationship between two or more numbers. Increase in the value of numbers that ratios to each other increase at a proportional rate.

The first step is to determine the amount of cream that is needed for 1 coffee = 3/8 ÷ 4

= 3/8 x 1/4 = 3/32

Amount of cream needed for 8 coffees = 3/32 x 8 = 3/4

Amount of cream needed for 16 coffees = 3/32 x 16 = 1 1/2

Now determine how much coffee is needed for 1 ounces of cream

4 ÷ 3/8

= 4 x 8/3 = 10 2/3

Amount of coffee needed for 1 1/8 ounces of cream = 10 2/3 x 1 1/8

32 / 3 x 9/8 = 12

A triangle is a three-edged polygon with three vertices. The area of the ΔDNE is 533 meters². The correct option is B.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The area of the triangle is half the product of its base and its height.

Area of triangle = (1/2) × base × height

Given the base of the triangle is 41 meters, while the height of the triangle is 26 meters.

Now, the area of the triangle DNE is,

Area of triangle = (1/2) × base × height

Area of ΔDNE = (1/2) × 41 meters × 26 meters

Step-by-step explanation:

An equation that could be used to determine M, the unknown side length of the logo is X = (36/5) x M

Let's assume that the unknown side length of the logo is 'M'. The logo is a rectangle, and the area of a rectangle is given by multiplying its length and width. Since we know the length of the logo is 7(1)/(5) feet, we can write the equation:

A = L x W

where A is the area of the logo, L is the length of the logo, and W is the width of the logo.

Substituting the given values, we get:

A = (7(1)/(5)) x M

or

A = (36/5) x M

Now, we know that the area of the logo is exactly the maximum area allowed by the building owner. Let's assume this maximum area is 'X'. So, we can write another equation:

A = X

Combining both equations, we get:

X = (36/5) x M

This is the required equation that could be used to determine the unknown side length 'M' of the logo if we know the maximum area allowed by the building owner 'X'.

Answer:

We can use proportion to solve this problem.

Let x be the cost of one invitation.

We can set up a proportion:

58/x = 87/1

To solve for x, we can cross-multiply:

58 * 1 = 87 * x

58 = 87x

x = 58/87

x = 0.67

So one invitation costs $0.67.

To find the cost of 70 invitations, we can multiply the cost of one invitation by 70:

70 * $0.67 = $46.90

Therefore, it would cost Madison $46.90 to buy 70 invitations.
