1) The estimated probability of patrick flipping a head with his coin is; 0.45

2) The margin of error for Patrick's estimated probability is; 0.218

3) The confidence interval for the chance of flipping a head with his coin is; CI = (0.232, 0.668)

No, the 95% confidence interval does not contain 50% as a probability, so it will be illogical to think that Patrick's lucky coin has a probability different from 0.5

We are given;

Number of trials; n = 20

Number of successful outcomes; x = 9

Thus; Proportion; p^ = x/n = 0.45

Now, the formula for the confidence interval of proportions is;

CI = p^ ± z√(p^(1 - p^)/n)

where;

z√(p^(1 - p^)/n) is margin of error

1) Probability of Patrick flipping a head with his lucky coin is;

p^ = x/n = 9/20 = 0.45

2) The margin of error is from the formula;

z√(p^(1 - p^)/n)

z for 95% confidence level is 1.96. Thus'

E = 1.96√(0.45(1 - 0.45)/20)

E = 0.218

The width and the length of the slab are 2 meters and 12 meters, respectively

From the question, we have the following parameters that can be used in our computation:

Width of a rectangular slab of concrete = 10m less than the length.

Area = 24 m²

These parameters can be represented as

Width = Length - 10

Area = Length * Width

So, we have

w = l - 10

A = lw

Also, we have

A = 24

Substitute w = l - 10 in A = lw

A = l(l - 10)

So, we have

l(l - 10) = 24

Expand

l² - 10l = 24

This gives

l² - 10l - 24 = 0

Expand

l² + 2l - 12l - 24 = 0

Factorize

(l + 2)(l - 12) = 0

So, we have

l = -2 and l = 12

The length cannot be negative

So, we have

l = 12

Recall that

w = l - 10

So, we have

w = 12 - 10

Evaluate

w = 2

Hence, the dimensions are 2 meters and 12 meters, respectively

The rate of change of the table is -500

The average rate of change of a function, graph, table or ordered pair is simply the slope of the relation

The function is represented by the table of values

The interval of the function are the x values

So, we make use of  x values

x = 0 and x = 2

Start by calculating f(0) and f(2)

From the table, we have

f(0) = 30000

f(2) = 29000

So, the average rate over these intervals is calculated as:

Average rate = [f(2) - f(0)]/[2 - 0]

Substitute known values

Average rate = [30000 - 29000]/[0 - 2]

Simplify

Average rate = -500

Hence, the rate of change is -500

And 1.27 • 7600 = 9652, which is the ending balance.

This gets the same result as finding 27% of 7600 and adding it back on to 7600, but does it more efficiently.

Side-Angle-Side (SAS) Rule prove the congruency of the triangle

What is a triangle ?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Triangles can be divided into three sorts based on the lengths of their sides, and they are: Scalene. Isosceles. Equilateral.

The Side-Angle-Side rule is used to demonstrate whether a set of triangles is congruent. According to the SAS rule, two sides and the included angle of one triangle must equal two sides and the included angle of another triangle in order for the two triangles to be considered congruent.

Prices of two ratios in the ratio is 4 : 1.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related.

For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole.

For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books.

The function of piecewise graph shown in the figure is,

f(x) = {y = 6   for x < -5

        { [tex]y = -\frac{19}{9}x-\frac{5}{9}[/tex]    for -5 ≤x < 5

        { y = 8/5x -14   for x ≥ 5

What is piecewise function?

A piecewise-defined function in mathematics is a function with several sub functions, each of which has a certain interval in the domain for which it is applicable. Piecewise definition is a method of expressing the function, not a property of the function.

From graph we can see that the first function is a line y = 6

Hence, f(x) = {y = 6    for x < -5}

Now to find the equation of second function.

From graph we get two points (-5, 10) and (4, -9).

First to find the slope

[tex]m = \frac{-9-10}{4+5} = \frac{-19}{9}[/tex]

Now to find the equation of line, using slope point form

[tex]y - 10 = \frac{-19}{9} (x-(-5))\\y-10=-\frac{19}{9}x-\frac{95}{9} \\ y=-\frac{19}{9}x-\frac{95}{9} + 10\\y = -\frac{19}{9}x -\frac{5}{9}[/tex]

So, f(x) = { [tex]y= -\frac{19}{9}x-\frac{9}{5}[/tex],    for -5 ≤ x < 5}

Now to find the equation of third line.

From graph we get two points (5, -6) and (10, 2).

First to find the slope of the line

[tex]m = \frac{2-(-6)}{10-5} = \frac{8}{5}[/tex]

Now to find the  equation of line, using slope point form

[tex]y-(-6)=\frac{8}{5}(x-5)\\ y+6=\frac{8}{5}x-8\\ y = \frac{8}{5}x - 14[/tex]

So, f(x) = {[tex]y = \frac{8}{5}x-14[/tex],   for x ≥ 5}.

1/2 package would be 1/2 of 24 which is 12

21 x 24 = 24

3 x 24 = 72

4 x 24 = 72

We know that 3 packages is 72 so 6 packages is double that at 144.  We also know that have a package is 12. so 144 + 12 = 156

Answer: See attached.

Step-by-step explanation:

        This slope-intercept form equation shows us that there is a y-intercept of -7. This means that (0, -7) will be a point on the line. Next, we have a slope of positive 3. This means we will count up three units, right one unit, plot a point. Then we repeat.

Answer:

start at the y-intercept, plot some points using the slope, then connect them using a straight line.

Step-by-step explanation:

Generally you'll have an equation in slope-intercept form, which is denoted as: [tex]y=mx+b[/tex]

This is a really useful form for a couple of reasons, and it has two key features. Firstly, the "m" represents the slope of the linear equation.

This makes sense the definition of slope is: [tex]\frac{\text{change in y}}{\text{change in x}}[/tex]

and we can generally define the points:

[tex]\text{at x = 1, y = }m(1)+b\implies m+b\\\text{at x = 2, y = } m(2)+b\implies m + m + b\\\text{at x = 3, y = }m(3) + b\implies m + m + m +b\\\text{and so on...}[/tex]

as the x value increases by 1, the change in y is the "m" value, we have one more "m" than the previous x-value, so the slope is the "m" value, which is the coefficient of the x variable.

The second key feature of slope-intercept form is the y-intercept, which is represented as "b" in this form. This also makes sense because the y-intercept is simply when the x-value is zero, and if you plug in x=0 into the equation, you're only left with the "b" value

Knowing these two things we can analyze the equation given:

[tex]y = 3x-7[/tex]

since it's given in slope-intercept form, we know that slope = 3, and y-intercept = -7. We immediately know one point, which is the y-intercept, since the x-value is going to be zero at the y-intercept, so one point on the graph is: (0, -7)

now from this point we can draw the graph by going to the right one, and up three, by definition of a slope (as x increases by 1, the y-value increases by 3).

We can do something similar on the left side, except instead of right one and up three, we go left one, and down three. You may be asking why down three? Well as you go right one, you go up three, this means if you compare the previous point to the new point, the previous point is down three compared to the new point (which is to the right one), so if you were to go back, you would be going left one and down three.

Now from these points you can do the same thing to extend the line a bit, and since it's a linear equation you can connect them using a straight line.

I also attached a graph from desmos to illustrate what I was saying a bit and also show the graph.

Right angle is an angle of 90 degrees while complementary angles add up to 90 degrees.

When the sum of two angles is 90°, then the angles are known as complementary angles.

Answer: Ad Hominum

Step-by-step explanation:

It just attacks the person.

Answers:

Team A = 175 people

Team B = 150 people

This is before the 45 students transfer from A to B.

===========================================================

Explanation:

x = number of people in team A

y = number of people in team B

These counts are before the 45 pupils transfer from A to B.

The counts are in ratio 7:6, which means,

x/y = 7/6

6x = 7y

x = 7y/6

If we subtract 45 people from team A, we have x-45 people left. Those 45 people go to team B to have y+45 pupils there.

The quantities x-45 and y+45 are in ratio 2:3, so,

(x-45)/(y+45) = 2/3

3(x-45) = 2(y+45)

3x-135 = 2y+90

3(7y/6)-135 = 2y+90 .... plug in x = 7y/6

21y/6 - 135 = 2y+90

6*( 21y/6 - 135 ) = 6*(2y+90)

21y-810 = 12y+540

21y-12y = 540+810

9y = 1350

y = 1350/9

y = 150

x = 7y/6

x = 7(150)/6

x = 175

We have 175 people on team A, and 150 people on team B.

This is before the 45 students transfer from A to B.

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

Check:

x/y = 175/150 = (7*25)/(6*50) = 7/6

This shows x and y are in ratio 7:6 to match the instructions.

x-45 = 175-45 = 130

y+45 = 150+45 = 195

(x-45)/(y+45) = 130/195 = (2*65)/(3*65) = 2/3

And we have the updated counts in the ratio 2:3, which matches the stated info in the instructions. The answers are fully confirmed.
