Santiago guesses that the marlin is over 1,500 pounds and might "dress out two thirds of that at thirty cents a pound." Do the math forSantiago

Answer: Let's use variables to represent the three digits of the number. We can use d1 for the first digit, d2 for the second digit, and d3 for the third digit. Based on the given information, we can write the following equations:

d1 > d2 + 4 (the first digit is greater than the second by 4)

d3 > d1 + 2 (the third digit is greater than the first by 2)

We also know that the three digits combine to form a three-digit number. We can write this number as:

100d1 + 10d2 + d3

To solve for the digits, we can use the information we have to write expressions for d1, d2, and d3 in terms of a single variable, and then use that to find the digits. Let's start with the first equation:

d1 > d2 + 4

Subtracting 4 from both sides, we get:

d1 - 4 > d2

Now we can substitute this expression for d2 in the second equation:

d3 > d1 + 2

d3 > (d1 - 4) + 2

d3 > d1 - 2

So we have the following inequalities:

d1 > d2 + 4

d3 > d1 - 2

We can use these to write expressions for d1, d2, and d3 in terms of a single variable, say x:

d1 = x + 4

d2 = x

d3 = x + 2 + 4 = x + 6

Now we can substitute these expressions into the equation for the three-digit number:

100d1 + 10d2 + d3 = 100(x+4) + 10x + (x+6) = 111x + 406

So the three-digit number can be written as 111x + 406. To find the digits, we need to choose a value of x that satisfies the inequalities we derived. Let's start with the first inequality:

d1 > d2 + 4

x + 4 > x + 4

x > 0

So x must be greater than 0. Now let's check the second inequality:

d3 > d1 - 2

x + 6 > x + 2

6 > 2

This inequality is always true, so we don't need to worry about it. Therefore, any value of x greater than 0 will satisfy the given conditions. For example, if we choose x = 1, then the digits are:

d1 = 5

d2 = 1

d3 = 7

And the three-digit number is:

100d1 + 10d2 + d3 = 500 + 10 + 7 = 517

So the number is 517.

[tex](2 \cdot \text{area of base}) + (\text{area of side})[/tex]

We can first solve for the surface area of a soup can, using the fact that its bases are circles.

[tex]A_{\text{circle}} = \pi r^2[/tex]

↓ substituting 3 for π

[tex]A_{\text{base}} = 3r^2[/tex]

[tex]A_{\text{base}} = 3(4)^2[/tex]

↓ simplifying

[tex]A_{\text{base}} = 48 \text{ cm}^2[/tex]

Then, we can solve for the area of its side, which we can think of as an elongated circumference (circumference multiplied by height).

[tex]A_{\text{circumference}} = \pi d[/tex]

[tex]A_{\text{side}} = h(\pi d)[/tex]

↓ substituting 3 for π

[tex]A_{\text{side}} = h(3d)[/tex]

The mean and standard deviation for Brett Favre's per game pass completions were 21.4 and 6.47, respectively, and all measurements fall within two standard deviations of the mean.

What is standard deviation ?

Standard deviation is a measure of the amount of variation or dispersion in a set of data. It is a statistic that indicates how much the individual data points deviate from the mean or average of the dataset.

a. Here's a stem-and-leaf plot for the number of passes completed by Brett Favre for each of the 16 regular season games in the fall of 2006:

Each stem represents the tens digit of the number of passes completed, and each leaf represents the ones digit.

b. To calculate the mean and standard deviation for Brett Favre's per game pass completions, we can use the following formulas:

mean = (sum of all values) / (number of values)

standard deviation = sqrt[(sum of (each value minus the mean) squared) / (number of values - 1)]

Using these formulas, we get:

mean = (15 + 31 + 25 + 22 + 22 + 19 + 17 + 28 + 24 + 5 + 22 + 24 + 22 + 20 + 26 + 21) / 16 = 21.4

standard deviation = [tex]sqrt[((15-21.4)^2 + (31-21.4)^2 + (25-21.4)^2 + (22-21.4)^2 + (22-21.4)^2 + (19-21.4)^2 + (17-21.4)^2 + (28-21.4)^2 + (24-21.4)^2 + (5-21.4)^2 + (22-21.4)^2 + (24-21.4)^2 + (22-21.4)^2 + (20-21.4)^2 + (26-21.4)^2 + (21-21.4)^2) / (16-1)] = 6.47 \\ \\= 6.47[/tex] (rounded to two decimal places)

Therefore, Brett Favre's per game pass completions had a mean of 21.4 and a standard deviation of 6.47.

c. To find the proportion of the measurements that lie within two standard deviations of the mean, we need to find the range of values that fall within two standard deviations above and below the mean. We can use the following formula:

range = mean ± (2 × standard deviation)

Plugging in the values we calculated in part b, we get:

range = 21.4 ± (2 × 6.47) = 8.46 to 34.34

Therefore, the mean and standard deviation for Brett Favre's per game pass completions were 21.4 and 6.47, respectively, and all measurements fall within two standard deviations of the mean.

Using basic arithmetic operation, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

The current value of Ann's bond investment can be calculated using the following formula:

Current Value of Bonds = Par Value x Market Rate

Since Ann has 7 bonds with a par value of $500 each, the total par value of her bond investment is:

$500 x 7 = $3,500

Using the market rate of 106.384, we can calculate the current value of Ann's bond investment as:

Current Value of Bonds = $3,500 x 1.06384 = $3,725.44

The current value of Ann's stock investment can be calculated by multiplying the number of shares she owns by the current stock price:

Current Value of Stock = Number of Shares x Stock Price

Since Ann owns 125 shares of Cilla Shipping stock and the current stock price is $30.65, the current value of her stock investment is:

Current Value of Stock = 125 x $30.65 = $3,831.25

To determine which investment has increased in value more, we need to compare the difference between the current and original values of each investment. The original value of Ann's bond investment is:

Original Value of Bonds = Par Value x Market Rate = $500 x 7 x 0.95626 = $3,346.78

The difference between the current and original value of Ann's bond investment is:

$3,725.44 - $3,346.78 = $378.66

The original value of Ann's stock investment is:

Original Value of Stock = Number of Shares x Stock Price = 125 x $28.00 = $3,500

The difference between the current and original value of Ann's stock investment is:

$3,831.25 - $3,500 = $331.25

Hence, Ann's stock investment has increased in value more, by $331.25, compared to her bond investment, which has increased in value by $378.66.

where is the number of sides

Since the number of sides of the polygon in the diagram is 6, we can find the sum of the interior angle.

Sum of interior angle = ( n − 2 ) × 180

Plug in n = 6

Sum of interior angle = ( 6 − 2 ) × 180

Sum of interior angle = ( 4 ) × 180

Sum of interior angle = 720°

Answer:

Step-by-step explanation:

To determine if the graphs of two linear equations are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel. If the slopes are not equal, then the lines are not parallel.

In case (a), the two equations are y = x + 3 and y = x + 6. Both equations have a slope of 1, which means the lines have the same steepness. However, the y-intercepts are different (3 and 6), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are parallel.

In case (b), the two equations are y = 4x - 1 and y = 1 - 4x. Both equations have a slope of -4, which means the lines have the same steepness. However, the y-intercepts are different (-1 and 1), which means the lines are shifted up or down relative to each other. Since the slopes are equal, but the y-intercepts are different, the lines are not parallel.

In case (c), the two equations are y = 2x - 3 and y = -2x + 3. The slopes of the two equations are 2 and -2, which are negative reciprocals of each other. This means the lines are perpendicular, not parallel.

In case (d), the two equations are 3y = x - 12 and 6y = 2x + 12. We can rewrite these equations in slope-intercept form by solving for y. The first equation becomes y = (1/3)x - 4 and the second equation becomes y = (1/2)x + 2. The slopes of the two equations are 1/3 and 1/2, which are not equal. Therefore, the lines are not parallel.

Answer:

22. Parallel

23. Not parallel

24. Not parallel

25. Parallel

Step-by-step explanation:

The slope equation form of a line is

y = mx + b

where

m = slope

b = y-intercept

If two lines are parallel their slopes, the value of m will be the same, in slope-intercept form

Q22

y = x + 33 → slope = 1
y = x + 6 →  slope = 1

Slopes are the same with = 1
Hence  the lines are parallel

Q23
y = 2x - 3  →  slope m = 2
y = -2x + 3  →  slope m = -2
Slopes not equal hence not parallel

Q24
y = 4x - 1 →  slope = 4
y = 1 --4x or y = - 4x + 1  → slope = - 4  

Slopes are different, hence not parallel

Q25
3y = x - 12
6y = 2x + 12

Divide the first equation by 3
=> 3y/3 = x/3 - 12/3
=> y = x/3 -4    →   slope = 1/3

Divide the second equation by 6
6y/6 = 2x/6 + 12/6
y = x/3 + 2  →   slope = 1/3

Slopes are same, hence parallel

In geometry, area is the measure of the amount of surface enclosed by a two-dimensional shape or a planar figure. It is typically measured in square units such as square centimeters, square inches, or square meters.

To find the area of a rectangle, we can multiply its length by its width.

Given width = 8 m and length = 16 m, the area of the rectangle is:

Area = length x width = 16 m x 8 m
Area = 128 cm^2 ------(I)

To find the area of a rectangle, we can multiply its length by its width.

Given width = 5 m and length = 6 m, the area of the rectangle is:

Area = length x width = 6 m x 5 m
Area = 30 m^2 -----(II)

The area of a triangle is given by the formula A = 1/2 x b x h, where A is the area, b is the base of the triangle, and h is its height.

Explanation:

Problem 1

Each time x goes up by 1, y goes down by 5. This constant rate of change leads to the equation being linear. The slope is m = -5/1 = -5. You can use the slope formula for any two points in the table to confirm this is the correct slope.

The y intercept is b = 15 because we have x = 0 lead to y = 15.

Therefore, we go from y = mx+b to y = -5x+15

-----------------------------------

Problem 2

Each time x goes up by 3, the y coordinate goes down by 3. Therefore, we have another linear equation here. The slope is m = -3/3 = -1.

The y intercept is b = 4 because x = 0 leads to y = 4.

y = mx+b turns into y = -x+4

-----------------------------------

Problem 3

Each time x goes up by 1, y is NOT going up the same amount. The jump from 10 to 20 is +10. The jump from 20 to 40 is +20. And so on.

Therefore, this equation isn't linear. Instead it's exponential. Each y term doubles when x increases by 1, so that's why the b term is b = 2.

The initial term is a = 80 because x = 0 leads to y = 80.

We go from y = a*b^x to y = 80*2^x

2. y = -x + 4.

3. y = 80(2^(x/3))

Step-by-step explanation:

1.

From the given data, we can see that as x increases by 1, y decreases by a fixed amount of 5. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

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

m = (0 - 30) / (3 - (-3))

m = -5

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 30 = -5(x - (-3))

y - 30 = -5x - 15

y = -5x + 15

So the equation for this linear relationship is y = -5x + 15.

From the given data, we can see that as x increases by 3, y decreases by a fixed amount of 3. This means that the relationship between x and y is linear, specifically a decreasing linear relationship.

To write the equation for a linear relationship, we need to find the slope (m) and y-intercept (b).

Using the formula for slope:

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

m = (-5 - 13) / (9 - (-9))

m = -18 / 18

m = -1

Using the point-slope form of a linear equation:

y - y1 = m(x - x1)

y - 13 = -1(x - (-9))

y - 13 = -1(x + 9)

y = -x + 4

So the equation for this linear relationship is y = -x + 4.

3.

From the given data, we can see that as x increases by 1, y doubles. This means that the relationship between x and y is exponential.

To write the equation for an exponential relationship, we can use the general form of an exponential function:

y = ab^x

where a is the initial value, b is the base, and x is the exponent.

To find a and b, we can use the first and fourth data points since they have the smallest and largest values of y, respectively.

When x = -3, y = 10, so we have:

10 = ab^(-3)

When x = 0, y = 80, so we have:

80 = ab^(0)

From the second equation, we can see that a = 80. Substituting this into the first equation, we get:

10 = 80b^(-3)

Simplifying, we get:

b = 2^(1/3)

So the equation for this exponential relationship is:

y = 80(2^(1/3))^x

Simplifying further:

y = 80(2^(x/3))

The probability is approximately 0.8185 or 81.85%.

Normal distribution, also known as Gaussian distribution, is a probability distribution that is commonly used in statistics, mathematics, and the natural sciences to describe real-valued random variables whose distributions are not known.

To find the probability that a randomly selected x-value from a normal distribution with a mean of 48 and a standard deviation of 7 is between 34 and 55, we need to standardize the values using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For x = 34:

z = (34 - 48) / 7 = -2

For x = 55:

z = (55 - 48) / 7 = 1

We can use a standard normal distribution table or a calculator to find the area under the standard normal distribution curve between z = -2 and z = 1. This area represents the probability that a randomly selected x-value from the given normal distribution is between 34 and 55.

Using a standard normal distribution table, we can find the probabilities as follows:

P(z < -2) = 0.0228 (from the table)

P(z < 1) = 0.8413 (from the table)

Therefore, the probability that a randomly selected x-value from the given normal distribution is between 34 and 55 is:

P(-2 < z < 1) = P(z < 1) - P(z < -2) = 0.8413 - 0.0228 = 0.8185

So, the probability is approximately 0.8185 or 81.85%.

The table which represents a linear function is answer B. By calculating the slope between any two points on the table.

A linear function is a mathematical function that produces a straight line when graphed. It is a type of function where the input variable (x) and output variable (y) are related in a way that can be represented by a straight line.

To determine which table represents a linear function, we need to check whether the change in the output variable (y) is proportional to the change in the input variable (x) for any two points on the table.

Answer A:

When we compare the difference between each value of y, we see that each subsequent value of y is multiplied by 2. For example, 2 x 2 = 4, 4 x 2 = 8, and so on. This means that there is a constant rate of change between each pair of x and y values, but the rate of change is not constant. Therefore, the function is not linear.

Answer B:

When we compare the difference between each value of y and x, we see that the difference between any two values of y is proportional to the difference between the corresponding x values. Specifically, when x increases by 1, y increases by 1, except for the first two values. This means that the rate of change between each pair of x and y values is constant, and the function is linear.

Answer C:

When we compare the difference between each value of y, we see that the difference between any two values of y is not proportional to the difference between the corresponding x values. Specifically, the rate of change is not constant. Therefore, the function is not linear.

Answer D:

When we compare the difference between each value of y, we see that the rate of change is not constant. Specifically, the rate of change from x = 1 to x = 2 is different from the rate of change from x = 2 to x = 3. The function is not linear.

Therefore, only answer B represents a linear function.

Therefore, the correct answer is option 4: 5x + 3y = 80.

A mathematical statement that shows the equivalence of two formulas is what an equation through algebra means. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are split by the 'equal' symbol.

Let the number of 3-point questions answered correctly be x, and the number of 5-point questions answered correctly be y. Then, we can form two equations based on the information given:

3x + 5y = 80 (total score equation)

x + y = ?? (number of questions answered equation)

We cannot determine the exact value of x + y from the given information, so we will leave it as an unknown.

The correct equation that represents the number of 33-point questions, x, and the number of 5-point questions, y, he answered correctly is:

5x + 3y = 80

This equation comes from the fact that the student only answered 3-point and 5-point questions correctly. Therefore, the only way for the student to get a score of 80 is if the number of 3-point questions he answered correctly is a multiple of 3 and the number of 5-point questions he answered correctly is a multiple of 5. Thus, we can write:

x = 33n, where n is a non-negative integer (since the number of 3-point questions he answered correctly must be a multiple of 33)

y = 5m, where m is a non-negative integer (since the number of 5-point questions he answered correctly must be a multiple of 5)

Substituting these expressions into the total score equation, we get:

3(33n) + 5(5m) = 99n + 25m = 80

Simplifying this equation, we get:

5x + 3y = 80

Therefore, the correct answer is option 4: 5x + 3y = 80.

What are algebraic equations?

An algebraic equation is a mathematical expression that includes one or more variables and mathematical operations such as addition, subtraction, multiplication, and division. The equation asserts that two expressions are equal.

The goal in solving an algebraic equation is to determine the value(s) of the variable(s) that make the equation true. Algebraic equations are used to solve problems in various fields such as physics, engineering, economics, and finance.

In the equation 3s + 135 = 4.5(s + 10), the expression (s + 10) represents the total number of rolls sold (small and large).

To see why, let's break down the equation:

3s represents the total amount earned from selling small rolls (since the

club earns $3.00 for every small roll sold).

4.5(s + 10) represents the total amount earned from selling all the rolls (small and large). The (s + 10) part represents the total number of rolls sold, since the club sold 10 more large rolls than small rolls, which is represented by adding 10 to the number of small rolls sold (s).

Therefore, the correct answer is (C) the total number of rolls sold (small and large).
