a) m = -0.5

b) The percentage of men in this city who smoke has decreased at a rate of 0.5% per year after 1990.

The slope of the model, m, represents the rate of change of the dependent variable (y) with respect to the independent variable (z). In this case, the slope is -0.5 which means that for every one year increase in time (z) after 1990, the percentage of men smoking cigarettes (y) decreases by 0.5%. This means that the rate of change of male smokers in this city over time is decreasing.

The length of mid segment of trapezoid is given by the equation (1)

[tex]length of mid segment = \frac{b1 + b2}{2} [/tex]

The given trapezoid ABCD has following properties

AD and BC are the bases of the trapezoid.

Mid segment of trapezoid = EF

AD = 4

EF = 2x + 8

BC = 5x + 5

b1 = AD

b2 = BC

[tex]EF = \frac{AD + BC}{2} [/tex]

[tex]2x \: + 8 = \frac{4 + 5x + 5}{2} [/tex]

[tex]4x + 16 = 5x + 9[/tex]

[tex]5x - 4x = 16 - 9[/tex]

[tex]x = 5[/tex]

so if we put in value of x in EF

we get,

EF = 2x + 8 = 2(2) + 8 = 4 + 8 = 12

Increase the length of the tube.

The natural frequency of a tube is determined by the speed of sound in the material of the tube and the length of the tube. Increasing the length of the tube will increase the wavelength of the standing waves that can be formed inside the tube, which in turn will increase the natural frequency of the tube. Decreasing the length of the tube will have the opposite effect, decreasing the natural frequency. Making holes in the tube will change the boundary conditions and may affect the natural frequency, but it is not a guaranteed way to increase it. Changing the composition of the tube will change the speed of sound in the material, which may increase or decrease the natural frequency depending on the new material's properties.

The number of students who own a cat are 17.

Given is a survey of the 30 students in Juan's class.

We can write -

Number of students who own dog = (1/2) x 30 = 15

Number of students who own dog and cat both = (2/3) x 15 = 10

Number of students who have no pets = 8

Number of students owning a cat alone = 30 - (15 + 8) = 7

Students who own a cat = 10 + 7 = 17

Therefore, the number of students who own a cat are 17.

Answer:

7.8

Step-by-step explanation:

7 plus 0 is 7 and .5 plus .3 is .8.

Answer: The answer (when finding s) is 7.8

Step-by-step explanation: The equation is fairly straight-forward. The equation is asking you what the variable s is equal to. You simply add 7.3 and 0.5. Since 5 and 3 is 8 that gives you the decimal 0.8, and there is nothing being done to the 7 making the answer 7.8

The hypotenuse of the triangle is equal to 14.14 feet, and thus the distance of the tree from the house is 14.14 feet.

Triangle is a three-sided, two-dimensional shape with three angles. It is one of the basic shapes in geometry and is formed by connecting three straight lines. Triangles can be classified based on their angles and sides. An equilateral triangle has all three sides equal in length and all three angles are equal. An isosceles triangle has two sides equal in length and two angles equal. An scalene triangle has all three sides and angles different in length and measure.

In order to determine the distance of the tree from the house, the Pythagorean theorem can be used. The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (hypotenuse).

Looking at the diagram, the sides of the triangle are 10 feet, 10 feet, and 12 feet. If we label the sides as a, b, and c, then we can use the Pythagorean theorem to solve for c:

a2 + b2 = c2

102 + 102 = c2

100 + 100 = c2

200 = c2

√200 = c

Therefore, the hypotenuse of the triangle is equal to 14.14 feet, and thus the distance of the tree from the house is 14.14 feet.

Answer:

The measure of VW is 6. It's because since the figures are congruent their names are written in correspondence ....so since VW corresponds to CD , the answer must be 6.

Step-by-step explanation:

Hi! I don't think you'll need much help on this one.  Just use the formula: a^2 + b^2 = c^2.  You know already that 20 = a and 24 = b.  Substitute them in and you'll get your answer!

Have a good day :_)

So, 3,500 tickets were sold for $15 each and 4,600 tickets were sold for $25 each.

Let x be the number of $15 tickets and y be the number of $25 tickets.

We know that:

x + y = 8,100 (the total number of tickets sold)

15x + 25y = $167,500 (the total amount of money made from ticket sales)

We can use the first equation to express y in terms of x:

y = 8,100 - x

We can substitute this expression of y into the second equation:

15x + 25(8,100 - x) = $167,500

Solving for x:

15x + 25(8,100) - 25x = $167,500

15x + 202,500 - 25x = $167,500

-10x = -35,000

x = 3500

So, 3,500 tickets were sold for $15 each and 8,100 - 3,500 = 4,600 tickets were sold for $25 each.

From the proportional method, we obtain that a group of 120 students will spend 9756 minutes.

In its most basic form, a ratio is a comparison between two comparable quantities.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, A group of 10 students spent 813 minutes of studying.

Let, 'x' be the number of minutes 120 students will spend their time in study.

This can be written in the proportional method as,

10 : 813 : : 120 : x.

10/813 = 120/x.

10x = 97560.

x = 9756 minutes.

Answer:

t = 16

Step-by-step explanation:

B and C are corresponding points.

D and E are also corresponding points.

Hence, BD = CE.

t + 90 = 10t - 54  ==> substitute t + 90 for BD and 10t - 54 for CE

t + 144 = 10t  ==> add 54 on both sides

144 = 9t  ==> subtract 9t on both sides

t = 16  ==> divide both sides by 9

The required explanation for log of base 10 is described.

The ability of logarithms to solve exponential problems is a large part of their strength. Examples of this include sound (measured in decibels), earthquakes (measured on the Richter scale), starlight brightness, and chemistry (pH balance, a measure of acidity and alkalinity).

The distinction between log and ln is that log is expressed in terms of base 10, while ln is expressed in terms of base e. As an illustration, log of base 2 is denoted by log2 and log of base e by loge = ln (natural log).

The logarithm can be rewritten using the general rule. The common logarithm, which has a base of 10 always, is what you're dealing with when the log has no base.

Let's find the slope.

[tex]A = (x_1,y_1) = (4,7) \text{ and } B = (x_2,y_2) = (2,3)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{3 - 7}{2 - 4}\\\\m = \frac{-4}{-2}\\\\m = 2\\\\[/tex]

The slope is 2.

Then apply point-slope form

[tex]\text{y} - \text{y}_1 = \text{m}(\text{x} - \text{x}_1)\\\\\text{y} - 7 = 2(\text{x} - 4)\\\\\text{y} - 7 = 2\text{x} + 2(-4)\\\\\text{y} - 7 = 2\text{x} -8\\\\\text{y} = 2\text{x} -8+7\\\\\text{y} = 2\text{x} -1\\\\[/tex]

Check:

Plug in x = 4. We should get y = 7 as the output.

y = 2x-1

y = 2*4-1

y = 8-1

y = 7

Therefore ,xa - xb = 3 and σa - σb = √(6/60) + (8/60) respectively are the units that were chosen and standard deviation difference.

How far the data points deviate from the mean is determined by descriptive statistics standard deviation. It quantifies how values are spread out over the sample data and gauges how far out of the mean data points are.

Here,

Given:

For Amanda's chicken, xa = 57 grammes is the average weight.

Chicken from Bernardo weighs, on average, 54 grammes.

The sample mean's difference is -

=> xa - xb

=> 57 - 54

=> 3

The chicken from Amanda's recipe had a standard deviation of 6 grammes.

The Bernardo's chicken standard deviation is b = 8 grammes.

N = 60 total observations were made.

The standard deviation formula is -

Mean

Step-by-step explanation:

Use the mean to find the average price since the numbers are far apart.

A line with a slope of 2 and a Y-intercept of -3 is described by the equation y is 2x - 3.

The slope of a line is represented by the value of m.

The y-intercept of this line is denoted by m = 2 c. c = -3

The slope-intercept is y = mx + c for the equation of the line.

Replace c = -3 with m = 2 and y = 2x - 3 in the previous equation.

As a result, the line's equation has the following values for the slope and Y-intercept: y = 2x - 3.

The slope-intercept is y = mx + c for the equation of the line.

Replace c = -3 with m = 2 and y = 2x - 3 in the previous equation.

So the equation of the line with a Y-intercept of -3 and a slope of 2 is y = 2x - 3.

So the equation of the line with a Y-intercept of -3 and a slope of 2 is y = 2x - 3.
