L=
Level 3
The coordinates of point L are (14, 17).
What is midpoint of two points?
A point B that is situated halfway between two other points, such as A and C, is said to be the midpoint. Because of this, finding the midpoint only requires measuring the length of the line segment and dividing it by 2.
Given:
KL has a midpoint at M(13.5, 15).
Point K is at (13, 13).
We have to find the coordinates of point L.
Since the midpoint of two points is calculated as,
\((\frac{x_1+x_1}{2}, \frac{y_1+y_2}{2} )= M\)
Here,
\((x_1, y_1) = (13, 13) M = (13.5, 15)\)
⇒ \((\frac{13 + x_2}{2}, \frac{13+y_2}{2} ) = (13.5, 15)\)
⇒ \(\frac{13 + x_2}{2}= 13.5, \frac{13 + y_2}{2} = 15\)
\(13 + x_2 = 27, 13 + y_2 = 30\\x_2 = 27 - 13, y_2 = 30 - 13\\x_2 = 14, y_2 = 17\)
Hence, the coordinates of L are (14, 17).

a decision maker subjectively assigned the following probabilities to the four outcomes of an experiment: , , , and . are these probability assignments valid? explain.
Yes, the probability assignments given to the four outcomes of an experiment are valid. Probabilities are calculated subjectively, and the decision maker assigned probabilities to the four outcomes of the experiment, which is perfectly acceptable.
Probability is a numerical measure of the likelihood of an event occurring, ranging from 0 to 1.
An event that is certain to happen has a probability of 1, while an event that is impossible has a probability of 0. The probability of any other event lies somewhere between 0 and 1.
Probability assignments, which are subjectively determined probabilities, are valid as long as they meet the following criteria:
The probabilities assigned must be between 0 and 1. The sum of the probabilities assigned to all potential outcomes must be 1.In this case, the probability assignments are valid because they meet both of the above criteria. The probabilities assigned are between 0 and 1, and when the probabilities are added together, the sum is 1.
Therefore, the given probability assignments are valid.

Han wants to build a dog house. He makes a list of the materials needed:
At least 60 square feet of plywood for the surfaces
At least 36 feet of wood planks for the frame of the dog house
Between 1 and 2 quarts of paint
Han's budget is $65. Plywood costs $0.70 per square foot, planks of wood cost $0.10 per foot, and paint costs $8 per quart.
write inequalities to represent the material constraints and cost constraints in this situation.
Answer:
a) \(p \geq 60\,ft^{2}\), b) \(w \geq 36\,ft\), c) \(1\,qt \leq q \leq 2\,qt\), d) \(0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65\)
Step-by-step explanation:
In this question we proceed to translate each sentence into mathematical language and, more specifically, inequations:
a) At least 60 square feet of plywood for the surface
Let \(p\) the surface area of plywood, measured in square feet, and the inequation is:
\(p \geq 60\,ft^{2}\) (Eq. 1)
b) At least 36 feet of wood planks for the frame of the dog house
Let \(w\) the total length of wood planks, measured in feet, and the inequation is:
\(w \geq 36\,ft\) (Eq. 2)
c) Between 1 and 2 quarts of paint
Let \(q\) the total capacity of paint, measured in quarts, and the inequation is:
\(1\,qt \leq q \leq 2\,qt\) (Eq. 3)
d) Han's budget is $ 65. Plywood costs $ 0.70 per square foot, planks of wood cost $ 0.10 per foot and paint costs $ 8 per quart.
Dimensionally speaking, we understand that cost equals unit cost multiplied by physical variable (i.e. Area, length or capacity). Let \(p\), \(w\) and \(q\) the surface area of plywood, the total length of wood planks and the total capacity of paint, respectively. The sentence is represented by the following inequation:
\(0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65\) (Eq. 4)
Write an inequality to represent each constraint(material and cost)
Inequality to represent cost constraints is 0.70p + 0.10pw + 8pa ≤ 65Plywood:
plywood ≥ 60 square feet
Planks:
planks ≥ 36 feet
Paints
1 quarts ≤ paints ≤ 2 quarts
Inequality to represent cost constraint
Plywood = $0.70
planks of wood = $0.10

Ramesh took a loan of Rs 50,000 from Urmila at the rate of 10% p.a. If he paid a half of the principal and all the interest at the end of 3 years, in how many years should he pay the remaining amount with total interest of Rs 20,000 from the beginning?
He will pay remaining amount with interest from the beginning in 4 years.
How many will he pay the remaining amount?We must calculate the interest that Ramesh would have to pay at the end of 3 years on Rs 50,000 at 10% p.a. The simple interest will be:
= (Principal x Rate x Time)/100
= (50,000 x 10 x 3)/100
= Rs 15,000
Total amount to pay at the end of 3 years would be:
= Rs 50,000 (principal) + Rs 15,000 (interest)
= Rs 65,000.
Ramesh paid half of principal (Rs 25,000) with interest of Rs 15,000. So, remaining amount to pay is:
= Rs 25,000 (principal) + Rs 20,000 (interest)
= Rs 45,000.
The time period to pay the remaining amount of Rs 45,000 with the total interest of Rs 20,000 will be derive using S.I. formula:
20,000 = (45,000 x 10 x Time)/100
Time = (20,000 x 100)/(45,000 x 10)
Time = 4.44444444444

A microscope gives you a circular view of an object in which the apparent diameter in your view is the microscope's magnification rate times the actual diameter of the region the microscope is examining. Your lab's old microscope had a magnification rate of 12, but you just got a new microscope with a magnification rate of 15. Both microscopes have an apparent diameter of 5in. How much more of the sample's area did the old microscope contain within its view?
The old microscope contained 2.5 square inches more of the sample's area than the new microscope.
Given that the apparent diameter of both the old microscope and the new microscope is 5 inches and the magnification rate of the old microscope is 12, and that of the new microscope is 15. Now, we need to find the actual diameter of the region of the microscope which is given by the equation: Apparent diameter = Magnification rate × Actual diameter.
Rearranging the above formula to solve for the actual diameter, we get Actual diameter = Apparent diameter / Magnification rate. Now, let's calculate the actual diameter for both the old microscope and the new microscope as follows: Actual diameter of the old microscope = \(5 / 12 = 0.42 inches\). Actual diameter of the new microscope =\(5 / 15 = 0.33 inches\).
Now, to find the area of the circular view of the old microscope, we use the formula for the area of a circle given as Area of a circle =\(\pi r^2\) Where r is the radius of the circle. Area of the old microscope = \(\pi (0.21)^2\)= \(0.139\)square inches.
Similarly, the area of the circular view of the new microscope = \(\pi (0.165)^2\)= 0.086 square inches. Therefore, the old microscope contained\(0.139 - 0.086 = 0.053\) square inches more than the new microscope. The old microscope contained 2.5 square inches more of the sample's area than the new microscope.

To find (f ∘ g)(x), we need to substitute g(x) into f(x) and simplify the expression. First, we substitute g(x) = 1 − 6x into f(x):
f(g(x)) = [(1 − 6x) − 1]^3.
Next, we simplify the expression inside the parentheses:
[(1 − 6x) − 1] = -6x.
Now, we substitute -6x back into the expression for f(g(x)):
f(g(x)) = (-6x)^3.
Simplifying further, we raise -6x to the power of 3:
(-6x)^3 = -216x^3.

number of tickets purchased?
A 4. 00
B 0. 25
C 1. 00
D 0. 10
answer=To find the constant of proportionality, we need to determine the rate at which the total cost changes with respect to the number of tickets purchased.
We can use the information given in the table to find the slope of the line that represents this relationship.
Using the points (8, 2.00) and (12, 3.00), we can calculate the slope as:
slope = (3.00 - 2.00) / (12 - 8) = 0.25
Using the points (12, 3.00) and (20, 5.00), we get the same result:
slope = (5.00 - 3.00) / (20 - 12) = 0.25
Using the points (20, 5.00) and (30, 7.50), we get:
slope = (7.50 - 5.00) / (30 - 20) = 0.25
Using the points (30, 7.50) and (50, 12.50), we get:
slope = (12.50 - 7.50) / (50 - 30) = 0.25
Since the slope is the same for all pairs of points in the table, we can conclude that the relationship between total cost and number of tickets purchased is a linear relationship, and the constant of proportionality (the rate of change of y with respect to x) is:

) the average lifespan for a certain type of vehicle is 8 years and follows an exponential distribution. a lot contains 200 of these vehicles, brand new. (a) how many of the 200 would you expect to fail in their first 2 years? (b) what is the approximate probability that 50 or more of them fail in their first 2 years? (c) if you have learned that 30 vehicles have already failed in under 2 years, what is the approximate probability that no more than 10 of the rest of them fail in their first 2 years?
a) We would expect approximately 0.2325 × 200 = 46.5 vehicles
to fail in their first 2 years. Since we cannot have a fraction of a vehicle
failing, we would expect around 46 or 47 vehicles to fail in their first 2
years.
b) The approximate probability that 50 or more vehicles fail in
the first 2 years is 0.0004.
c) The approximate probability that no more than 10 of the remaining
vehicles fail in their first 2 years, given that 30 have already failed, is 0.0002.
a) The average lifespan of the vehicle is 8 years, and it follows an
exponential distribution, which has a probability density function of
\(f(x) = (1/θ) \times e^(-x/θ)\),
where θ is the mean of the distribution. Thus, θ = 8.
The probability that a vehicle fails in the first 2 years can be found by
integrating the exponential probability density function from 0 to 2:
P(X ≤ 2) = ∫[0,2] f(x) dx = ∫[0,2] (1/8) × e^(-x/8) dx
Using a calculator or a table of integrals, we can find this probability to
be approximately 0.2325.
b) The number of vehicles that fail in the first 2 years follows a Poisson
distribution with parameter λ = 200 × P(X ≤ 2) = 200 × 0.2325 = 46.5.
The probability that 50 or more vehicles fail in the first 2 years can be
found using the Poisson distribution with parameter λ = 46.5:
P(X ≥ 50) = 1 - P(X < 50)
Using a Poisson distribution table or a calculator, we can find that P(X <
50) is approximately 0.9996.
Thus, P(X ≥ 50) = 1 - 0.9996 = 0.0004 (approximately).
c) Given that 30 vehicles have already failed in under 2 years, we need
to find the probability that no more than 10 of the remaining 170 vehicles
fail in their first 2 years.
The number of vehicles that fail in the first 2 years follows a Poisson
distribution with parameter λ = 170 × P(X ≤ 2) = 170 × 0.2325 = 39.525
(rounded to 40).
Thus, we need to find P(Y ≤ 10), where Y is a Poisson random variable
with parameter λ = 40.
Using a Poisson distribution table or a calculator, we can find that P(Y ≤
10) is approximately 0.0002.
