The angles of the triangle with sides 11, 12 and 20 are approximately 117.6 degrees.
We are given that;
The angles of triangle sides are 11, 12 and 20.
Now,
To find the angles of a triangle when its sides are given, we can use the law of cosines. The law of cosines states that c^2 = a^2 + b^2 - 2ab cos©, where a, b, and c are the sides of the triangle and C is the angle opposite to side c.
Using this formula, we can find the angle opposite to side 20 as follows: [tex]cos© = (a^2 + b^2 - c^2) / 2ab cos© = (11^2 + 12^2 - 20^2) / (2 * 11 * 12) cos© = -0.45 C = arccos(-0.45) C[/tex] = 117.6 degrees
Similarly, we can find the other two angles:[tex]cos(A) = (b^2 + c^2 - a^2) / 2bc cos(A) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) cos(A) = 0.25 A = arccos(0.25) A[/tex] = 75.5 degrees
[tex]cos(B) = (a^2 + c^2 - b^2) / 2ac cos(B) = (11^2 + 20^2 - 12^2) / (2 * 11 * 20) cos(B) = -0.55 B = arccos(-0.55) B[/tex]= 87 degrees
The triangle with sides 11, 12 and 20 are approximately 117.6 degrees, 75.5 degrees, and 87 degrees
Therefore, by the angle the answer will be 117.6 degrees.

Convert the rectangular coordinates (–6, 6) to polar coordinates.
Answer: A Polar is (6√2, [tex]\frac{3\pi }{4}[/tex])
Step-by-step explanation:
Draw a line to point (see image). You need to find the length of that line and then the angle. Polar(length, angle)
Using pythagorean theorem
length² = (6)² + (-6)²
length² = 36 +36
length =√72
length = [tex]\sqrt{36 *2}[/tex]
length = 6√2
To find angle:
The triangle size is 6-6-6√2 Let's proportionally shrink so we can use unit circle numbers to figure angle. Becomes: 1-1-√2
So when we do sin x = opp/adj
sin x = [tex]\frac{1}{\sqrt{2} }[/tex] >get rid of radical on bottom
sin x = [tex]\frac{\sqrt{2} }{2}[/tex] > when is sin = [tex]\frac{\sqrt{2} }{2}[/tex] This happens at [tex]\frac{\pi }{4}[/tex] but we are in the 2nd quadrant so the angle is [tex]\frac{3\pi }{4}[/tex]
Polar is (6√2, [tex]\frac{3\pi }{4}[/tex])
The polar coordinates are (6([tex]\sqrt[]{2}[/tex], 3pi/4).
Rectangular coordinates are in the form of (x, y) and Polar coordinates are expressed in the form of (r, [tex]\theta[/tex]).
Relation between polar coordinates and rectangular coordinates-x = r cos([tex]\theta[/tex]), y = r sin([tex]\theta[/tex]) and x^2 +y^2 =r^2 ...(1)
So by using above formulas we can solve our question.
Here , x= -6 and y= 6
r^2 = (-6)^2 +(6)^2
=72
=>r = 6([tex]\sqrt[]{2}[/tex])
Put the values of x and y in the mentioned formula in eq(1)
-6 = 6([tex]\sqrt[]{2}[/tex] )cos[tex]\theta[/tex]
6 = 6([tex]\sqrt[]{2}[/tex] )sin([tex]\theta[/tex]),
=>-1/([tex]\sqrt[]{2}[/tex] = cos([tex]\theta[/tex]) , 1/[tex]\sqrt[]{2}[/tex]= sin[tex]\theta[/tex]
Here cos is negative and sin is positive so it lies in 2nd quadrant
so here [tex]\theta[/tex] lies between [tex]\frac{\pi}{2} \leq\theta\leq\pi[/tex]
[tex]\theta[/tex]= π-π/4
=3π/4
So,(r, [tex]\theta[/tex]) = ( 6√2, [tex]\frac{3\pi}{4}[/tex] )

The values of m and n are 15 and 19, respectively in the given data.
From the given values:
x: 1, 2, 7, 4, 9
y: 3, 5, 11, m, n
Looking at the x-values, we can observe that they are increasing by 1 each time.
Looking at the y-values, we can observe that they are increasing by 2 each time except for the last two values (m and n) which are unknown.
Based on this pattern, we can establish the following equation:
y = 2x + 1
Now, let's calculate the values of m and n using this equation:
For x = 7:
y = 2(7) + 1
y = 14 + 1
y = 15
Therefore, m = 15.
For x = 9:
y = 2(9) + 1
y = 18 + 1
y = 19
Therefore, n = 19.
Hence, the values of m and n are 15 and 19, respectively.

Brynen is driving to a new job five days this week. He drives 27 miles each way. His car gets 35 miles per gallon of gas. How many gallons of gas will he use driving to and from work this week? Round to the nearest tenth.
Brynen will use 7.71 gallons of gas driving to and from work this week.
To calculate the gallons of gas Brynen will use driving to and from work this week, we need to consider the round trip distance and the car's fuel efficiency.
Given:
Brynen drives 27 miles each way to work.
His car gets 35 miles per gallon of gas.
To find the total distance Brynen will travel in a week, we need to calculate the round trip distance for each workday and multiply it by the number of workdays (five days).
Round trip distance = 27 miles (one-way distance) * 2 = 54 miles (round trip distance)
Total distance traveled in a week = 54 miles (round trip distance) * 5 days = 270 miles
Next, we can determine the total gallons of gas Brynen will use using his car's fuel efficiency.
Gallons of gas used = Total distance / Fuel efficiency
Gallons of gas used = 270 miles / 35 miles per gallon
Gallons of gas used ≈ 7.71 gallons (rounded to the nearest tenth)
Therefore, Brynen will use approximately 7.71 gallons of gas driving to and from work this week.
It's important to note that this calculation assumes that Brynen's car maintains a consistent fuel efficiency of 35 miles per gallon throughout the entire week and that no additional driving outside of the work commute is considered. Factors such as traffic, variations in fuel efficiency, or additional trips would affect the actual gas consumption.

In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally distributed with a mean of 55.7 inches, and standard deviation of 2.6 inches.
What is the probability that the height of a randomly chosen child is between 52.2 and 60.6 inches? Do not round until you get your your final answer, and then round to 3 decimal places.
Answer=
(Round your answer to 3 decimal places.)
Answer: Therefore, the probability that the height of a randomly chosen child is between 52.2 and 60.6 inches is 0.884. Rounded to 3 decimal places, the answer is 0.884.
Step-by-step explanation:We can use the standard normal distribution to find the probability that the height of a randomly chosen child is between 52.2 and 60.6 inches.
First, we need to standardize the values using the formula:
z = (x - mu) / sigma
where:
x = 52.2 and 60.6 (the values we want to find the probability between)
mu = 55.7 (the mean)
sigma = 2.6 (the standard deviation)
For x = 52.2:
z = (52.2 - 55.7) / 2.6 = -1.346
For x = 60.6:
z = (60.6 - 55.7) / 2.6 = 1.885
Next, we use a standard normal distribution table or calculator to find the area between these two z-scores:
P(-1.346 < z < 1.885) = 0.884
Therefore, the probability that the height of a randomly chosen child is between 52.2 and 60.6 inches is 0.884. Rounded to 3 decimal places, the answer is 0.884.

Answer:
Step-by-step explanation:
To find the arithmetic means in the given sequence, we need to determine the missing numbers between 175 and 235.
Let's calculate the differences between consecutive terms:
1st difference: 235 - 175 = 60
2nd difference: (Next number) - (Previous number) = (Next number) - 235
Since the differences are constant, we can add the same value to each term to find the missing numbers.
Let's calculate the missing numbers using the 1st difference:
175 + 60 = 235
175 + 60 + 60 = 295
175 + 60 + 60 + 60 = 355
Now we have the complete sequence: 175, 235, 295, 355.
To find the arithmetic means, we take the average of consecutive terms:
1st arithmetic mean: (175 + 235) / 2 = 205
2nd arithmetic mean: (235 + 295) / 2 = 265
3rd arithmetic mean: (295 + 355) / 2 = 325
Among the given choices, the correct answer is:

The coordinates of point M are (1, 2).
The gradient of CB is 5.
The equation of line AD in the form y = mx + c is: y = (-1/5)x + 37/5.
To solve the given problem, we can follow these steps:
1. Calculate the coordinates of point M:
Since the diagonals of a rhombus bisect each other, the midpoint of the diagonal AC will give us the coordinates of point M.
Midpoint formula:
x-coordinate of M = (x-coordinate of A + x-coordinate of C) / 2
= (-3 + 5) / 2
= 2 / 2
= 1
y-coordinate of M = (y-coordinate of A + y-coordinate of C) / 2
= (8 - 4) / 2
= 4 / 2
= 2
Therefore, the coordinates of point M are (1, 2).
2. The gradient (slope) of a line passing through two points (x₁, y₁) and (x₂, y₂) can be found using the formula:
Gradient (m) = (-4 - 1) / (5 - 6)
= -5 / -1
= 5
Therefore, the gradient of CB is 5.
3. To find the equation of line AD, we need to calculate the gradient (m) of AD and the y-intercept (c).
Gradient of CB = 5
Gradient of AD = -1/5 (negative reciprocal of 5)
To find the y-intercept (c), we can substitute the coordinates of point A (-3, 8) into the equation y = mx + c and solve for c:
8 = (-1/5)(-3) + c
8 = 3/5 + c
c = 8 - 3/5
c = 40/5 - 3/5
c = 37/5
Therefore, the equation of line AD in the form y = mx + c is:

The patient is to receive 250ml of D5W with 10 units of oxytocin (Pictocin) IV at the rate of 0.002 units/min. How many ml per hour.
Answer:
0.5ml/hr
Step-by-step explanation:
Given:
Infusion rate: 0.002 units/min
To convert the infusion rate from units/min to ml/hr, we need to know the flow rate conversion factor specific to the medication and solution being administered.
In this case, we have the information that the patient is receiving 10 units of oxytocin (Pictocin) in 250 ml of D5W solution.
To calculate the ml/hr rate, we can use the following formula:
ml/hr = (Infusion rate in units/min * Volume in ml) / Time in min
ml/hr = (0.002 units/min * 250 ml) / 1 min
ml/hr = 0.5 ml/min
Therefore, the infusion rate of 0.002 units/min is equivalent to 0.5 ml/hr.

Michelle’s robotics club plans to sell reusable water bottles with their logo as a fundraiser. They buy 75 water bottles for $443.25. They agree to sell each water bottle for 25% more than the price at which they were purchased. At what price should they sell each water bottle?
The required selling price of each water bottle is $554.06 such that Michelle's robotics club will achieve 25% increase in the purchase price.
Given that number of water bottles purchased is 75 and cost price (C,P) of the 75 water bottles is $443.25. The increase % on the purchase price is profit % = 25%.
To calculate the selling price when cost price and profit % is given by following steps:
Step 1 - Calculate the 25% of the cost price which gives profit.
Step 2 - Calculate SP, Selling price = Cost price + profit.
That implies, Profit = 25% of C.P.
Profit = 25/100 × 443.25.
Therefore, Profit = $110.81.
That implies, Selling price(S.P) = Cost price + profit.
S.P = 443.25 + 110.81.
Thus, S.P = $554.06.
Hence, the required selling price of each water bottle is $554.06 such that Michelle's robotics club will achieve 25% increase in the purchase price.

The statement, yes, they are independent because P(student) = 0.8 and P(student | logo A) = 0.8.
To determine if being a student and preferring logo A are independent events, we need to compare the probabilities of these events occurring.
The probability of being a student, denoted as P(student), is given as 0.8. This means that out of the total population (125), 80% are students.
The probability of a student preferring logo A, denoted as P(student | logo A), is given as 0.8.
This means that out of the students (100), 80% prefer logo A.
If the events of being a student and preferring logo A are independent, then the probability of a student preferring logo A (P(student | logo A)) should be the same as the probability of being a student (P(student)).
However, in the given options, both options A and D state that P(student | logo A) = 0.8, which is the same as P(student).
This suggests that being a student and preferring logo A are independent events.

Option C is the correct answer.
We have,
To find the height of the right cylinder, we need to use the given information of the diagonal length and the total surface area.
The diagonal length of a right cylinder can be found using the formula:
diagonal = √(height² + radius²)
Given that the diagonal length is 37, we can set up the equation:
37 = √(height² + radius²)
We also know that the total surface area of a right cylinder is given by:
surface area = 2πrh + 2πr²
Given that the total surface area is 492π, we can set up the equation:
492π = 2πrh + 2πr²
Simplifying the surface area equation, we have:
246 = rh + r²
Now we have a system of equations:
37 = √(height² + radius²)
246 = rh + r²
Since we only need to find the height of the cylinder, we can focus on the first equation:
37 = √(height² + radius²)
Squaring both sides of the equation, we get:
37² = height² + radius²
1369 = height² + radius²
Substituting the second equation (246 = rh + r²) into the equation above, we have:
1369 = height² + (246 - rh)
Simplifying further, we get:
1369 = height² + 246 - rh
Now, let's analyze the answer options:
a. 35
b. 42
c. 25
d. 17
e. 32
We need to substitute each value into the equation and check if it satisfies the equation.
After checking each option, we find that the height that satisfies the equation is:
c. 25
Therefore,
The height of the cylinder is 25.

The amount of fast fashion waste (w) produced by city with a population (x)
is given by W=f(x). Waste is measured in tons per season (autumn/winter,
or spring/summer) and population is measured in thousand of people. The
city of Dunwoody, Georgia has a population of 53,300 and produces 5 tons
of waste fashion during the autumn/winter season. Express this in terms of
(f) and write a statement explaining what the means
The function implies that a city with a population of 53.3 thousand people produces 5 tons of fast fashion waste during the autumn/winter season.
How to explain the functionThe city of Dunwoody, Georgia has a population of 53,300, which is equal to 53.3 thousand people. So, we can express this in terms of f as follows:
W = f(53.3) = 5
This means that the function f(x) gives the amount of fast fashion waste produced by a city with a population of x thousand people. In this case, f(53.3) = 5, which means that a city with a population of 53.3 thousand people produces 5 tons of fast fashion waste during the autumn/winter season.
This is a significant amount of waste, and it is important to be aware of the environmental impact of fast fashion. Fast fashion is a term used to describe the rapid production of cheap, trendy clothing.

Suppose that the mean daily viewing time of television is 8.35 hours. Use a normal probability distribution with a standard deviation of 2.5 hours to answer the following questions about daily television viewing per household
(a)
What is the probability that a household views television between 3 and 11 hours a day? (Round your answer to four decimal places.)
(b)
How many hours of television viewing must a household have in order to be in the top 3% of all television viewing households? (Round your answer to two decimal places.)
hrs
(c)
What is the probability that a household views television more than 5 hours a day? (Round your answer to four decimal places.)
Answer:
(a) To find the probability that a household views television between 3 and 11 hours a day, we need to calculate the z-scores for 3 and 11 hours using the formula z = (x - μ) / σ, where μ is the mean and σ is the standard deviation. The z-score for 3 hours is (3 - 8.35) / 2.5 = -2.14 and the z-score for 11 hours is (11 - 8.35) / 2.5 = 1.06. Using a standard normal distribution table, we find that the probability of a z-score being between -2.14 and 1.06 is approximately 0.8209.
(b) To find how many hours of television viewing a household must have in order to be in the top 3% of all television viewing households, we need to find the z-score that corresponds to the top 3% of the standard normal distribution. Using a standard normal distribution table, we find that this z-score is approximately 1.88. Using the formula x = μ + zσ, we can calculate that a household must view television for approximately 8.35 + (1.88 * 2.5) = 12.75 hours to be in the top 3% of all television viewing households.
(c) To find the probability that a household views television more than 5 hours a day, we need to calculate the z-score for 5 hours using the formula z = (x - μ) / σ, where μ is the mean and σ is the standard deviation. The z-score for 5 hours is (5 - 8.35) / 2.5 = -1.34. Using a standard normal distribution table, we find that the probability of a z-score being greater than -1.34 is approximately 0.9099.
Answer:
Step-by-step explanation:
The mean daily viewing time of television is 8.35 hours and the standard deviation is 2.5 hours. We can use a normal probability distribution to answer the following questions about daily television viewing per household:
(a) The probability that a household views television between 3 and 11 hours a day is 0.9772 (rounded to four decimal places).
(b) To be in the top 3% of all television viewing households, a household must have 15.68 hours of television viewing per day (rounded to two decimal places).
The probability that a household views television more than 5 hours a day is 0.8944 (rounded to four decimal places).
