The polynomial area of the framed picture is (27 + 2x) * (15 + 2x) and the value is 693 square units

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

The given parameters are

Width = 15

Length = 27

Also, we have

Length of the frame = x

This means that the area of the framed picture is

Area = (Length + 2 * Length of the frame) * (Width + 2 * Length of the frame)

Substitute the known values in the above equation

Area = (27 + 2x) * (15 + 2x)

In (a), we have

Area = (27 + 2x) * (15 + 2x)

When x = 3, we have

Area = (27 + 2 x 3) * (15 + 2 x 3)

Evaluate

Area = 693

Hence, the area is 693 square units

Answer: maturity value = $17816.67

Explanation:

The formula for calculating simple interest is expressed as

I = PRT

where

I is the interest

P is the principal or initial amount

R is the interest rate

T is the time in years

From the information given,

P = 17104

R = 12.5% = 12.5/100 = 0.125

We would convert 4 months to years. Recall

12 months = 1 year

4 months = 4/12 = 1/3

Thus, the interest is calculated as follows

I = 17104 x 0.125 x 1/3 = 712.67

maturity value = principal + interest

maturity value = 17104 + 712.67

maturity value = $17816.67

Answer:

The answer would be 36.

The dimensions of the rectangular poster are:

Width = 3 inches.

Length = 9 inches.

A rectangle usually has a long side called the length, and a shorter side called the width.

The area of the rectangle is calculated by multiplying the length and the width together. Therefore, formula for the area of a rectangle is:

Area = (length)(width).

The rectangular poster has the following parameters:

Let x represent the width of the rectangular poster.

Width of the rectangular poster = x

Length of the rectangular poster = 3x

Area of the rectangular poster = 27 in.².

Plug in the values

(x)(3x) = 27

3x² = 27

Divide both sides by 3

3x²/3 = 27/3 [division property of equality]

x² = 9

Take the square root of both sides

√x² = √9

x = 3

Width of the rectangular poster = x = 3 inches.

Length of the rectangular poster = 3x = 3(3) = 9 inches.

In ten year you will be 10 years older than you are now and so will your brother. The 6 years difference will remain if no one dies.

Step-by-step explanation:

You are z years old

Your brother is 6 years younger than z years; z - 6 years

In 10 years time, you will be z + 10 years

Your brother will be z - 6 years + 10 years = z + 4 years

Because the prisms are stacked onto one another, they have a total volume of 320 cubic units

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following parameters

The volume of a prism is the prodict of its dimensions

This means that

Cube = Length^2

Cuboid = Base area * Height

So, we have the following equations

Shape 1 = a^3

Shape 2 =a^2b

Shape 3 =a^2c

Substitute the known values in the above equation

So, we have

Shape 1 = a^3 = 4^3 = 64

Shape 2 =a^2b = 4^2 * 6 = 96

Shape 3 =a^2c = 4^2 * 10 = 160

Add the above values

Prism volume =64 + 96 + 160

Step-by-step explanation:

If you select four socks at random, the probability that at most three are blue is 42.9%.

Probability is the likelihood of an expected outcome occurring when many possible events can happen.

Probability is represented in percentages, fractions, and decimals to show that it describes what is likely from many outcomes.

The total number of socks in the drawer = 14

The number of blue socks = 8

The number of black socks = 6

The probability of getting a blue sock = 8/14

The probability of getting 3 out of 4 = 3/4

The combined probability = 8/14 x 3/4

= 42.86%

= 42.9%

Thus, when you randomly select four socks, you can probably get blue socks 42.9% of the time.

Answer:

Tom is currently 5 and Bill is currently 11

Step-by-step explanation:

Let b = Bill's current age

Let t = Tom's current age

We have 2 unknowns so we need to equations to solve for this.

b = t + 6  

(b-3) = 4(t-3)  We have to subtract 3 from both Tom and Bill's current age

b- 3 = 4t - 12  Distribute the 4 and then substitute in t + 6 for b.

t + 6 -3 = 4t -12  Combine like terms

t + 3 = 4t -12  Subtract t from both sides of the equation

3 = 3t - 12  Add 12 to both sides of the equation

15 = 3t  Divide both sides by 3

5 = t  Tom is 5.  Since Bill is 6 years old, her is 11.

Check:

11 = 5+ 6

Three years ago, Tom would have been 2 and Bill would have been 8.  Bill is four times older than Tom.  2x4 = 8.

Statistics can be misleading by faulty sampling and inaccurate graphs

The gathering, characterization, analysis, and drawing of inferences from quantitative data are all tasks that fall under the purview of statistics, a subfield of applied mathematics. Probability theory, linear algebra, and differential and integral calculus play major roles in the mathematical theories underlying statistics.

Given Data

Statistics can be misleading.

Statistics is quite powerful. So much so that some of the most significant decisions made by individuals and organizations were based on statistics. The adage that "statistics don't lie" may actually be true. However, statistics can occasionally be deceptive, and depending on how they are used, the same type of data can demonstrate the opposite tendency.

Sometimes inaccurate information is purposefully supplied in order to influence individuals and forward a goal. Similarly, it can also occur as a result of negligence or just failing to comprehend the data.

Knowing the various ways statistics can be abused will help you spot them and avoid making decisions based on skewed or inaccurate information.

1)Faulty sampling

The info can due to the sampling strategy employed to gather the data, be deceptive. For instance, the size and kind of the sample used in any statistics has a big impact. Since many surveys and polls are directed at specific groups of people who give particular answers, the sample sizes tend to be tiny and skewed.

2)Inaccurate graphs

Data manipulation can be done in a variety of ways, not just by using descriptive statistics incorrectly. You can identify them if you are aware of them.

3)Chooser Data Display

This type of data visualization might be perplexing and exaggerate differences. If you look at the data and consider how much variety there is in the numbers, you can spot false graphs in the media.

4)Absence of Baseline

Checking to see if the start-at-zero criteria has been adhered to is another approach to spot a deceptive graph. In a graph, The New York Times demonstrated that its sales are double those of The Daily Telegraph. However, if you look at the scale, you can see that the sales difference is just about 10%.

Given that,

We have to find the first 3 pairs of opposite integers.

Opposite integers means the "counting numbers" (sometimes known as integers), as well as zero, are integers. The pairs of integers known as opposite integers share the same absolute value, or, to put it another way, are equally spaced from zero. The numbers 10 and -10 are the opposites. The numbers 43 and -43 are the opposites.
