The cost of each admission tickets is 37.5 dollars.

Ms Boi spent a total of 175 dollars for 4 admission ticket and for parking at a baseball game. The cost of each admission ticket was the same amount, including tax. The cost of the parking was 25 dollars.

Therefore, the equation that can be use to determine the cost, i of each admission ticket can be represented as follows:

Therefore,

175 = 4i + 25

subtract 25 from both sides of the equation

175 = 4i + 25

175 - 25 = 4i + 25 - 25

150 = 4i

divide both sides by 4

Therefore, the width of the bridge is approximately 5.9 feet. Therefore, the height of the bridge is approximately 8.4 feet. Therefore, the length of CH is approximately 36.9 feet. Therefore, the measure of angle BHC is approximately 189 degrees. Therefore, the answer to part (e) is no.

A triangle is a closed, two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry, and is formed by connecting three non-collinear points. The sum of the interior angles of a triangle is always 180 degrees, and there are several types of triangles including equilateral, isosceles, and scalene.

Here,

To solve this problem, we will use the fact that AAGC is congruent to AEGC. This means that angle ACG is equal to angle AEC, and angle AGC is equal to angle AEG.

(a) To determine the width AE of the bridge, we can use the tangent function. We have:

tan(27°) = AE/12

Solving for AE, we get:

AE = 12 tan(27°) ≈ 5.9 ft

(b) To determine the height CG of the bridge, we can use the same approach. We have:

tan(36°) = CG/12

Solving for CG, we get:

CG = 12 tan(36°) ≈ 8.4 ft

(c) To determine the length of CH, we can use the Pythagorean theorem. We have:

CH² = CG² + GH²

Substituting the values we found earlier, we get:

CH² = (8.4 ft)² + (40 ft - 5.9 ft)²

CH² = 70.56 ft² + 1288.41 ft²

CH² = 1358.97 ft²

Taking the square root, we get:

CH ≈ 36.9 ft

(d) To determine the measure of angle BHC, we can use the fact that angles AGC and AEG are congruent. We have:

angle BHC = 180° - angle AHC - angle CHB

angle AHC = angle ACG - angle HCG = 27° - 36° = -9° (note that this is a negative angle because it is measured clockwise)

angle CHB = angle CGB - angle HCG = 36° - 36° = 0°

Substituting these values, we get:

angle BHC = 180° - (-9°) - 0°

angle BHC = 189°

(e) To determine whether CH bisects angle ZACG, we need to show that angle CAH is congruent to angle CAG. We have:

angle CAH = 180° - angle HCG - angle ACG

= 180° - 36° - 27°

= 117°

angle CAG = 180° - angle ACG - angle AGC

= 180° - 27° - 27°

= 126°

Since angle CAH is not congruent to angle CAG, we can conclude that CH does not bisect angle ZACG.

a. The temperature is about 3.35 degrees Celsius at 340 m/s, the speed of sound.

b. The temperature is about 2.35 degrees Celsius at 320 m/s, or the speed of sound.

Speed is a scalar physical quantity that quantifies the rate of motion of an object. It is described as the distance that an object covers in a specific period of time. Meters per second (m/s) is the SI unit for measuring speed.

The speed formula is as follows:

Speed = distance / time

Depending on the purpose, speed can also be stated in different units, such as kilometres per hour (km/h), miles per hour (mph), or feet per second (ft/s).

The concept of speed, which is used to describe how objects move, is important to physics. It plays a significant role in a variety of fields of science, engineering, and technology, including sports, aircraft, and transportation. For the purpose of analysing and forecasting the behaviour of physical systems, it is essential to comprehend the idea of speed.

a. We can change v = 340 into the equation and solve for t to determine the temperature when the speed of sound is 340 m/s:

v = 20Vt + 273

340 = 20Vt + 273

67 = 20Vt

t = 67/20

Therefore, the temperature is about 3.35 degrees Celsius when the sound travels at 340 m/s.

b. We may once more enter v = 320 into the equation and solve for t to determine the temperature when the speed of sound is 320 m/s:

v = 20Vt + 273

320 = 20Vt + 273

47 = 20Vt

t = 47/20

As a result, the temperature is roughly 2.35 degrees Celsius at 320 m/s, the speed of sound.

P = [tex]\left[\begin{array}{ccc} 0.3&0.7 \\ 0.6&0.4\end{array}\right][/tex]

b) To find the percentage of the market share that brand A gets after two years, we need to multiply the initial market share vector (40% for brand A and 60% for other brands) by the transition matrix twice:

| 0.4 0.6 | × P × P = | 0.404 0.596 |

Therefore, after two years, brand A is expected to have 40.4% of the market share.

c) To find the long-run market share for brand A, we need to find the steady-state vector of the transition matrix P. This is the vector π such that:

πP = π

and

π ₁+ π₂ = 1

where π₁ is the long-run probability of being in state 1 (using brand A) and π₂ is the long-run probability of being in state 2 (not using brand A).

The value of the function f/g is (x - 1) / (x + 8)

Let's start by writing out the functions we are given:

f(x) = 4 / (x + 8)

g(x) = x / (x - 1)

To find f/g, we need to divide f(x) by g(x). We can do this by multiplying f(x) by the reciprocal of g(x), which is (x - 1) / x. Multiplying f(x) by this reciprocal gives us:

f(x) * (x - 1) / x = 4 / (x + 8) * (x - 1) / x

To simplify this expression, we can first find a common denominator for the two fractions on the right-hand side:

4 / (x + 8) * (x - 1) / x = 4(x - 1) / x(x + 8)

Now we can simplify this expression by canceling out any common factors in the numerator and denominator. In this case, we can cancel out a factor of 4 and a factor of (x - 1):

4(x - 1) / x(x + 8) = (x - 1) / (x + 8)

Therefore, the quotient of f(x) and g(x), or f/g, is:

f/g = (x - 1) / (x + 8)

We can interpret this expression as a new function, h(x), where h(x) = f(x) / g(x) = (x - 1) / (x + 8). This new function takes a value of x and returns the ratio of f(x) to g(x) at that value.

Sum

Mean = (4.1 + 3.2 + 2.8 + 2.6 + 3.7 + 3.1 + 9.4 + 2.5 + 3.5 + 3.8) / 10

Mean = 36.7 / 10

Mean = 3.67

To find the median, we need to put the values in order:

2.5, 2.6, 2.8, 3.1, 3.2, 3.5, 3.7, 3.8, 4.1, 9.4

The middle number is the median, which is 3.35 in this case (3.2+3.5)/2.

To find the mode, we look for the value that appears most often. In this case, there is no mode as no value appears more than once.

To find the first quartile (Q1), we need to find the value that separates the bottom 25% of the data from the top 75%. We can do this by finding the median of the lower half of the data:

2.5, 2.6, 2.8, 3.1, 3.2

The median of this lower half is 2.8, so Q1 = 2.8.

To find the third quartile (Q3), we need to find the value that separates the bottom 75% of the data from the top 25%. We can do this by finding the median of the upper half of the data:

3.7, 3.8, 4.1, 9.4

The median of this upper half is 3.95, so Q3 = 3.95.

To find the outlier, we can use the rule that any value more than 1.5 times the interquartile range (IQR) away from the nearest quartile is considered an outlier. The IQR is the difference between Q3 and Q1:

IQR = Q3 - Q1

IQR = 3.95 - 2.8

IQR = 1.15

1.5 times the IQR is 1.5 * 1.15 = 1.725.

The only value that is more than 1.725 away from either Q1 or Q3 is 9.4. Therefore, 9.4 is the outlier in this data set.

Answer:

Step-by-step explanation:

Mean is the average of the data vales : 38.7 (sum of all values) divided by 10 (the number of values).  Mean = 38.7/10 = 3.87

Median is the "middle" number" = put the date in order and find the middle value:

2.5, 2.6, 2.8, 3.1, 3.2, 3.5, 3.7, 3.8, 4.1, 9.4, since there is no middle data value, find the average of the 2 in the middle.

3.2 + 3.5/2 = 6.7 ÷ 2 = 3.35 - median

All values appear once so there is no mode.

First quartile is the middle of the lower set of data = 2.8

Third quartile is the middle of the upper set = 3.8

The outlier is 9.4.

How to calculate the outlier:

First you need the IQR which is the diffence of Q3 - Q1,

so the IQR is 3.8- 2.8 = 1

Outliers are the quartile + or - (1.5)(IQR)

Q1 -(1.5)(1) = 2.8 - 1.5 = 1.3

Q3 - (1.5)(1)= 3.8 + 1.5 =4.5

So anything below 1.3 or above 4.5 is an outlier.

First we find the mean of the x-values and mean of the y-values.

The mean of the x-values would be,

[tex]\bar{X}[/tex] = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8) / 8

[tex]\bar{X}[/tex] = 4.5

and the mean of the y-values would be,

[tex]\bar{Y}[/tex] = (3.8 + 5.8 + 6.2 + 7.5 + 7.2 + 8.3 + 9.3 + 8.5) / 8

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years)

In this case, we have:

P = $4,000.00

r = 15% = 0.15

n = 1 (compounded annually)

t = 6 years

Substituting into the formula, we get:

A = 4000(1 + 0.15/1)^(1*6)

A = 4000(1.15)^6

A ≈ $10,359.73

Therefore, the amount in the account after 6 years, rounded to the nearest cent, is $10,359.73.

1) (f - g) (x) = f(x) - g(x) = x ≤ 1/4  

Domain of the function is : [1/4, infinity)

2) → [tex]\frac{f}{g}(x) =\frac{f(x)}{g(x)} = \frac{-x+4}{\sqrt{4x-1} }[/tex]        

Domain of the function : (1/4, infinity)

We have the function are as follows:

f(x) = -x + 4

g(x) = [tex]\sqrt{4x+1}[/tex]

To find the f - g and f/g and also their domains using interval  notation.

Now, (f - g) (x) = f(x) - g(x)

                       = [tex]-x+4-\sqrt{4x+1}[/tex]

                       = 4x + 1 ≤ 0

                       = x ≤ 1/4            

Domain of the function is : [1/4, infinity)

→ [tex]\frac{f}{g}(x) =\frac{f(x)}{g(x)} = \frac{-x+4}{\sqrt{4x-1} }[/tex]

=> 4x - 1 > 0

=> x > 1/4

Domain of the function : (1/4, infinity)
