Martin is two years older than Reese, and the same age as Lee. If Lee is 12, how old is Reese?
Answer:
x-2= Reese's age
Martin and Lee are the same age (12), and 2 years older than Reese. So, to know how old Reese is, you have to subtract 2 from the ages of Martin and Lee. Hence, the equation, 'x-2', because 'x' can be substituted with Martin or Lee's age.

Q1. Mr. A, while filling up the insurance application form, states his age as 25 believing it to be true. His actual age was 27. The Life Insurance Corporation issued a policy in his favour charging a lower premium than what it should have charged if the actual age had been given. Is this valid?
Q2. Mr. A, saw a newspaper advertisement regarding an auction sales of old furniture in Ontario. He booked a flight from Calgary to Ontario and took a cab in Ontario to reach the venue of auction. When he reached there, the auction was cancelled. Can he file suit for damages?
Q3. P engages B to kill C and borrows $100 from D to pay B. If D is aware of the purpose of the loan, is this valid agreement?
Q4. A paid $500 to a Government servant to get him a contract for the building cafeteria. The Government servant could not get the contract. Can A recover $500 paid by him to the Government servant?
In this case, Mr. A stated his age as 25 believing it to be true. However, his actual age was 27.
This is not a valid agreement. If the insurer has issued a policy, based on any misrepresentation, the insured has no right to claim under the policy. A saw a newspaper advertisement regarding an auction sale of old furniture in Ontario.
Mr. A cannot file a suit for damages because the newspaper advertisement regarding the auction sale of old furniture in Ontario did not contain any guarantee or assurance to the effect that the auction would actually take place.

A quality-control manager randomly selects 100 bottles of ketchup that were filled on January 19 to assess the calibration of the filling machine. What is the population in the study? OA. All bottles of ketchup produced in the plant in the given year O B. The 100 bottles of ketchup selected in the plant on January 19. OC. The 100 bottles of ketchup selected in the plant O D. All bottles of ketchup produced in the plant on January
The population in the study is the entire set of bottles of ketchup produced in the plant in the given year.
In the given scenario, the quality-control manager selects 100 bottles of ketchup filled on January 19 to assess the calibration of the filling machine. The population refers to the entire group or set of items that are of interest to the researcher. In this case, the researcher wants to evaluate the calibration of the filling machine for all bottles of ketchup produced in the plant throughout the given year.
Option A, which states that the population is all bottles of ketchup produced in the plant in the given year, is the correct choice. This option aligns with the objective of the study, which is to assess the calibration of the filling machine for all bottles of ketchup produced in the plant. The sample, on the other hand, refers to the subset of items that are selected from the population and used for analysis. In this case, the sample consists of the 100 bottles of ketchup that were randomly selected on January 19.
Options B and C are incorrect because they refer to the specific set of 100 bottles selected on January 19, which represents the sample, not the population. Option D is also incorrect because it refers only to the bottles produced on January 19, whereas the study aims to evaluate the calibration of the filling machine for all bottles produced throughout the given year. Therefore, the correct answer is option A, which represents the entire population of bottles of ketchup produced in the plant in the given year.

kyle and ryan take entrance exams at two different universities. kyle scores a 489 on an exam with a mean of 400 and a standard deviation of 67, while ryan scores a 39 on an exam with a mean of 35 and a standard deviation of 2. which do you think is more likely to be accepted at the university of his choice?
We cannot definitively say which of them is more likely to be accepted based solely on their exam scores. We can use z-scores to compare the performance of Kyle and Ryan.
For Kyle:
z-score = (x - mean) / standard deviation = (489 - 400) / 67 = 1.33
For Ryan:
z-score = (x - mean) / standard deviation = (39 - 35) / 2 = 2
Comparing the z-scores, we see that Ryan performed better relative to his peers than Kyle did. This is because Ryan's z-score of 2 is larger than Kyle's z-score of 1.33.
However, it's important to note that acceptance into a university is based on multiple factors, not just exam scores. Therefore, we cannot definitively say which of them is more likely to be accepted based solely on their exam scores.

To solve an inequation for x you have to follow the same procedure you follow when solving equations, with exception that when you multiply/divide by a negative number the direction of the inequality gets inverted.
So to solve the given inequelity for x, you have to pass "+49" to the other side of the expression. To do so, subtract it from both sides of the expression:

Prove that : tan (x-y) + tan (y-z) +tan (z-x) = tan (x-y) tan (y-z) tan (z+x)
The identity can be proven using the identity: tan (A + B) = (tan A + tan B)/(1 - tan A tan B).
The identity "tan (x-y) + tan (y-z) + tan (z-x) = tan (x-y) tan (y-z) tan (z+x)" is not true for all values of x, y, and z. This is because the tangent function is not one-to-one, meaning that different inputs can result in the same output, and it can also be undefined for some inputs.
The identity can be proven true only in certain special cases where the tangent function is defined and one-to-one. For example, if x, y, and z are chosen such that x, y, and z are all acute angles, the identity can be proven using the identity: tan (A + B) = (tan A + tan B)/(1 - tan A tan B)
where A and B are angles. Let's start with the definition of tangent:
tan A = sin A/cos A
Similarly,
tan B = sin B/cos B
Now, we can use the sum formula for sine and cosine:
sin (A + B) = sin A cos B + cos A sin B
cos (A + B) = cos A cos B - sin A sin B
Dividing the above two equations, we get:
tan (A + B) = (sin A cos B + cos A sin B) / (cos A cos B - sin A sin B)
Using the definition of tangent, we can simplify the above expression:
tan (A + B) = (tan A + tan B) / (1 - sin A sin B/cos A cos B)
Since sin A/cos A = tan A and sin B/cos B = tan B, we can simplify further:
tan (A + B) = (tan A + tan B) / (1 - tan A tan B)
However, this proof is quite involved and beyond the scope of this answer.
In general, it is recommended to use other methods, such as graphical visualization or trigonometric identities, to solve problems involving the tangent function.
Therefore, The identity can be proven using the identity: tan (A + B) = (tan A + tan B)/(1 - tan A tan B).

To conduct a test of hypothesis with a small sample, we make an assumption that the population is normally distributed .
What is normal distribution?
A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean.
The normal distribution appears as a "bell curve" on a graph.
A probability bell curve is more properly described as the normal distribution.The mean and standard deviation of a normal distribution are 0 and 1, respectively. It has a kurtosis of 3 and zero skew.Not all symmetrical distributions are normal, but all normal distributions are symmetrical.Natural occurrences frequently resemble the usual distribution.To know more about normal distribution........

Find an expression for the total number of students who are in the math club or the telescope club but not both. Give your answer in simplest form.
The number of students in the telescope club by $x$ and the number of students in the math club by $y$.
$y=2x$Now, suppose there are $z$ students who are members of both clubs. Then the total number of students who are in the math club or the telescope club (or both) is given by:$x + y - z$ Substituting $y=2x$ in the above expression, we get:$x + 2x - z=3x - z$ Hence, the expression for the total number of students who are in the math club or the telescope club (or both) is $3x - z$.b)The number of students who are in the math club but not in the telescope club is given by:$y-z$ And the number of students who are in the telescope club but not in the math club is given by:$x-z$ Adding these two expressions, we get the total number of students who are in the math club or the telescope club but not both:$ y-z+x-z $.

Answer:
∠A= 111.75°
Step-by-step explanation:
Please see the attached picture.
∠B +∠C= 180° (adj ∠s on a str. line)
(x +35)° +∠C= 180°
∠C= 180° -(x +35)°
∠C= 145° -x°
∠A= ∠C (corr. ∠s)
∠A= 145° -x°
Given that ∠A is (3x +12)°, equate this expression to the expression we found.
145° -x°= 3x° +12°
3x° +x°= 145° -12°
4x°= 133°
x°= 133° ÷4 (÷4 on both sides)
x°= 33.25°
Substitute the value of x back into the expression for ∠A:
∴∠A= 3(33.25°) +12°
∠A= 111.75°

The ratios for angle A are as follows:
sin A = Opposite/Hypotenuse
cos A = Adjacent/Hypotenuse
tan A = Opposite/Adjacent
In the triangle with angle A measuring 55°, and side X measuring 16 units, we can use the sine ratio to find the value of x:
sin A = Opposite/Hypotenuse
sin 55° = x/16
Solving for x, we have:
x = 16 * sin 55°
x ≈ 13.06 (rounded to the nearest tenth)
In the triangle with side X measuring 8 ft and angle measuring 41°, we can use the cosine ratio to find the value of x:
cos A = Adjacent/Hypotenuse
cos 41° = x/8
Solving for x, we have:
x = 8 * cos 41°
x ≈ 6.06 (rounded to the nearest degree)
In the triangle with sides measuring 7 and 22 units, we can use the Pythagorean theorem to find the value of x:

sqrt(9×9×2) - sqrt(3×3×7) + sqrt(8) - sqrt(28)
and let's present these numbers as the product of their basic prime factors
sqrt(3×3×3×3×2) - sqrt(3×3×7) + sqrt(2×2×2) - sqrt(2×2×7)
now we see that we have 2 pairs of square roots : 1 pair ends with a factor of 2, and one pair with a factor of 7.
let's combine these
sqrt (3×3×3×3×2) + sqrt(2×2×2) - sqrt(3×3×7) - sqrt (2×2×7)
and now we move the factors of 2 and 7 back out in front (of course, we need to apply the square root on these factors) :
9×sqrt(2) + 2×sqrt(2) - 3×sqrt(7) - 2×sqrt(7) =
