Answer 2

Angle ∠B is a right-angle then the measure of angle ∠A is 43.6 degrees and the measure of angle ∠C is 46.4 degrees.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function. The Pythagoras is the sum of the square of two sides is equal to the square of the longest side.

The triangle ΔABC is given.

The angle ∠B is a 90°.

Then the value of the angle ∠C will be

[tex]\rm C = \sin ^{-1} \dfrac{21}{29}\\\\C = 46.40^o[/tex]

Then the value of the angle ∠A will be

     ∠A + ∠C = 90°

∠A + 46.40° = 90°

              ∠A = 43.6°

How do i write 9 1/3 as a fraction greater than 1

Answers

To write 9 1/3 as a fraction greater than 1, we can convert the mixed number into an improper fraction.

Step 1: Convert the whole number to a fraction.

9 can be written as 9/1.

Step 2: Find the common denominator.

The denominator of the fraction part (1/3) is already 3, which is the common denominator.

Step 3: Add the fractions.

9/1 + 1/3

Step 4: Determine the new numerator.

To add the fractions, we need a common denominator. Since the denominators are already the same, we can add the numerators:

(9 + 1)/3 = 10/3

The fraction 10/3 represents 9 1/3 as an improper fraction. To express it as a fraction greater than 1, we can divide the numerator by the denominator:

10 ÷ 3 = 3 remainder 1

This means that the improper fraction 10/3 can be written as 3 and 1/3.

Therefore, 9 1/3 can be written as the fraction 10/3, which is greater than 1.

Problem 5 Let X₁.....Xy be iid according to EX= for all i=1,2,.... Define Y = 1 if X, > density function of Y₁. a continuous probability density fx. Suppose and Y₁ = 0 otherwise. Find the probability

Answers

Given that X1, X2, ..., Xy are i.i.d according to the probability density function fx such that EX = 2. Define Y = 1 if X > 2 and Y = 0 otherwise.

Find P(Y = 1).

Given that X1, X2, ..., Xy are i.i.d according to the probability density function fx such that EX = 2. Thus the probability density function is,fx = 1/2  for x ∈ (0, 2) fx = 0  elsewhere

Therefore, P(X > 2) = ∫2∞ fx dx= ∫2∞ 0 dx= 0Now, P(Y = 1) = P(X > 2) = 0

Hence, the required probability is 0. Therefore, the correct option is (D) 0.

Likelihood is a proportion of the probability of an occasion to happen. Numerous occurrences cannot be completely predicted. Using it, we can only predict the chance of an event happening, or how likely it is to happen.

The probability of an event occurring is determined by dividing the total number of possible outcomes by the number of favorable outcomes. A coin flip is the simplest illustration. There are only two outcomes that can occur when flipping a coin; either heads or tails is the outcome.

Calculate the property tax on a condominium located in a city in British Columbia and assessed at $525,200 if the current tax rate is 1.426%.

Answers

The property tax on a condominium assessed at $525,200 in a British Columbia city with a current tax rate of 1.426% is $7,492.55.

Calculating property taxes involves multiplying the assessed value of a property by the current tax rate. In this case, we have a condominium located in a city in British Columbia, with an assessed value of $525,200 and a tax rate of 1.426%.

To determine the property tax amount, we need to multiply the assessed value by the tax rate. First, we convert the tax rate from a percentage to a decimal by dividing it by 100. In this case, 1.426% becomes 0.01426.

Next, we multiply the assessed value ($525,200) by the tax rate (0.01426). The calculation is as follows:

$525,200 x 0.01426 = $7,492.35

Therefore, the property tax on the condominium amounts to $7,492.35.

Lind domain and Range for 9x) = 1-dx²_X+2 without graphing. Prove that [0, 1] & [11, 21]

Answers

The domain of the function is all real numbers, and the range is [0, 1] and [11, 21].

To find the domain and range of the function f(x) = 1 - dx² - x + 2, we can analyze its properties without graphing.

Domain:

The domain of a function consists of all the valid input values, or the values of x for which the function is defined. In this case, the only restriction we need to consider is the square root of a negative number.

In the given function, there are no square roots involved. Therefore, the function is defined for all real numbers. The domain is the set of all real numbers, which can be represented as (-∞, ∞).

Range:

The range of a function consists of all the possible output values, or the values that f(x) can take. To determine the range, we need to consider the behavior of the function as x approaches positive or negative infinity.

As x approaches positive or negative infinity, the dominant term in the function is -dx². If d is positive, as x gets larger, the term -dx² becomes more negative, approaching negative infinity. Similarly, if d is negative, as x gets larger, the term -dx² becomes more positive, approaching positive infinity.

Since the remaining terms in the function (1-x+2) are constants, they do not affect the behavior as x approaches infinity. Therefore, the range of the function depends on the value of d.

If d is positive, the range of the function is (-∞, 1+d). As x approaches negative infinity, the function approaches positive infinity, and as x approaches positive infinity, the function approaches 1+d.

If d is negative, the range of the function is (1+d, ∞). As x approaches negative infinity, the function approaches 1+d, and as x approaches positive infinity, the function approaches negative infinity.

Given that the range is [0, 1] & [11, 21], we can conclude that d is positive, and the range is [0, 1+d]. Since the range also includes [11, 21], we can infer that 1+d = 11, and solving for d gives d = 10.

Therefore, the domain of the function is (-∞, ∞), and the range is [0, 1] & [11, 21].

Is (6, –2) a solution to this system of equations? y = –1/6 x − 1 y = 1/6 x − 3

Answers

Answer:

Yes, (6, -2) is a solution to the given system of equations.

Step-by-step explanation:

Please write  y = –1/6 x − 1 y = 1/6 x − 3 as follows, for greater clarity:

y = (–1/6)x − 1

y = (1/6)x − 3

Let's actually solve this system:

y = (–1/6)x − 1

y = (1/6)x − 3

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

2y = -4, or y = -2

Now find x.  Arbitrarily we choose to use the first equation for this purpose:

y = (-1/6)x - 1.  We set y = -2 and find x:    -2 = (-1/6)x - 1

Combining the constants, we get -1 = (-1/6)x, or 6 = x

Yes, (6, -2) is a solution to the given system of equations.

Answers

The two triangles, Triangle DEF ~ Triangle BCA. answer that DE = 3.6, EF = 1.47 and FD = 2.8.

Given the two triangles, Triangle DEF ~ Triangle BCA. Let us understand this notation first. '~' means 'is similar to'. So, it says that Triangle DEF is similar to Triangle BCA. The meaning of similarity is that the two triangles have the same shape but different sizes,

Similarly, angles E and C, as well as angles F and A, are corresponding angles. Since corresponding angles of similar triangles are congruent, we can write:D = B, E = C and F = ABy the transitive property of equality, we can write:D = B, E = C, F = A => DE = BC, EF = AB and FD = CA (using corresponding sides of the triangles).So, the triangles DEF and BCA are similar and their corresponding sides are proportional. Therefore, we can write: DE/BC = EF/AB = FD/CA = k (some constant)If we consider DE/BC = k, we can write: DE/k = BC and DE/k + EF/k = AB and (DE + EF)/k = FDAnd, from the given information, we know that CD = 3, EA = 4 and FB = 6.

So, we can write:BC + CD = 5 (since AB = EA + FB = 4 + 6 = 10 and AB/BC = EA/CD => BC = AB * CD/EA = 10 * 3/4 = 7.5)FD + CD = 9 (since FD/CA = EF/EA => FD = EF * CA/EA = 6 * 9/4 = 13.5)So, we get the following system of equations:DE/k + EF/k = 10/k = 2.5 (from the given EF = 2.5)DE/k = 7.5 - CD = 4.5 (from the equation BC + CD = 5)EF/k = AB - DE/k = 5.5 (using the first equation)DE/k + FD/k = 13.5/k (from the equation FD + CD = 9)DE/k = CD = 3 (from the given information)FD/k = 10.5/k (using the third equation)Solving these equations, we get:k = 3.75, DE = 13.5/3.75 = 3.6, EF = 5.5/3.75 = 1.47 and FD = 10.5/3.75 = 2.8.

So,we get the answer that DE = 3.6, EF = 1.47 and FD = 2.8.

the sum of squares can be 0 if there is no variation of the data points from the mean, or even a very large number if the variation is high.

Since the numbers are essentially squared, the only way to get a negative sum of squares is if imaginary numbers are involved, which is an impossible task in regression analysis as it deals with real data. Hence the sum of squares can never be negative.
