A sequence of transformations that maps △RST to △R′S′T′ is a reflection across the y=x line followed by a rotation of 90 degrees clockwise about the origin.

Explanation:

First, we need to reflect the original triangle RST across the y=x line. This will result in a new triangle that is congruent to the original one but with its vertices in different positions. The new vertices will be R(-1, -3), S(-1, -1), and T(-5, -4).

Next, we need to rotate this new triangle 90 degrees clockwise about the origin. This will result in another new triangle that is congruent to the previous one but with its vertices in different positions. The new vertices will be R'(3, -3), S'(3, -1), and T'(-1, -4), which are the vertices of △R′S′T′.

Therefore, the sequence of transformations that maps △RST to △R′S′T′ is a reflection across the y=x line followed by a rotation of 90 degrees clockwise about the origin.

Answer: F. n = s/180 + 2

Step-by-step explanation:

         To find the equation that solves for n, we will isolate the n variable.

Given:

     S = (n - 2) x 180

Divide both sides of the equation by 180:

     \(\frac{S}{180}\) = n - 2

Add 2 to both sides of the equation:

     \(\frac{S}{180}\) + 2 = n

Reflexive property:

    n = \(\frac{S}{180}\) + 2

                   F. n = s/180 + 2

Answer:

YZ , XZ , XY

Step-by-step explanation:

first lets find angle Z

angle x + angle y + angle z=180 degree (being sum of interior angles of a triangle)

27 + 48 + angle z=180

75 + angle z=180

angle z =180-75

angle z =105 degree

side YZ is the shortest one because the side opposite to the smallest angles is shortest in side.Then ,XZ is shortest in side because the side opposite to the smallest angle is shortest in side.Since angle z is largest angle so the side opposite to angle z will be the longest side i.e XY

first YZ then XZ and XY.

The product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

To compare two products, we need to compare the values of the products using the comparison operators (<, >, <=, >=, or =).

We can start by finding the sums of the original numbers (0, 1, 2, 3):

Sum of the original numbers = 0 + 1 + 2 + 3 = 6

Now, we add the number k to each of the numbers:

Sum of the new numbers = (0 + k) + (1 + k) + (2 + k) + (3 + k)

= (0 + 1 + 2 + 3) + 4k

= 6 + 4k

So, the new sums range from 6 + 4k (the smallest) to 9 + 4k (the largest).

The product of the least and the greatest of the sums is:

(6 + 4k) × (9 + 4k) = 54 + 60k + 16k^2

The product of the middle two sums is:

(7 + 4k) × (8 + 4k) = 56 + 60k + 16k^2

Comparing the two products using the comparison operators:

54 + 60k + 16k^2 < 56 + 60k + 16k^2 (since 54 < 56)

or

54 + 60k + 16k^2 <= 56 + 60k + 16k^2 (since the products are equal when k=0)

In conclusion, the product of the middle two sums is greater than or equal to the product of the least and the greatest of the sums.

Answer: 40.75

Step-by-step explanation:

The 'Pclass' predictor seems to be the best predictor of fare, as it was seen that the average fare increases as the passenger class increases.

The average fare in each category can be calculated by calculating the average fare for each category of the categorical predictors (excluding the first four). For example, for the 'Sibsp' predictor, the average fare can be calculated by taking the sum of all fares for each category and dividing it by the total number of passengers in that category.

The boxplots can then be used to visualize the average fares for each category of the categorical predictors. From the boxplots, it can be seen that the 'Pclass' predictor seems to be the best predictor of fare, as the average fare increases as the passenger class increases. Specifically, the average fare for passenger class 1 is much higher than that for passenger class 2 and 3, confirming that 'Pclass' is the best predictor of fare.

If twice a certain number plus 4 is at the same number plus 10. Then the number is 6.

Let x = the number

According to the given statement, "Twice a certain number plus 4 is at the same number plus 10," we can form an equation:

2x + 4 = x + 10

Solve this equation to find the value of x.

2x - x + 4 = x - x + 10

x + 4 = 10

Next, subtracting 4 from both sides of the equation:

x + 4 - 4 = 10 - 4

Simplifying:

x = 6

Therefore, the number is 6.

Step-by-step explanation:

143 —————>233 = 90

233 —————>237 = 3

90 + 3 = 93

The number of the whole numbers lying between 237 and 143 will be 94.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Zero, a consistently positive number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive values are negative in value. The set of integers is frequently represented in mathematical notation by the big bold letters Z.

The number of the whole numbers lying between 237 and 143 will be given by the subtraction of the numbers from 237 to 143. Then we have

The expected value of the continuous random variable V is 5. The expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

To calculate the expected value of a continuous random variable V with a given probability density function (PDF), we integrate the product of V and the PDF over its entire range.

The PDF of V is defined as:

f(v) = 6/24 = 0.25 for 3 ≤ v ≤ 7, and 0 otherwise.

The expected value of V, denoted as E(V), can be calculated as:

E(V) = ∫v * f(v) dv

To find the expected value, we integrate v * f(v) over the range where the PDF is non-zero, which is 3 to 7.

E(V) = ∫v * (0.25) dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * ∫v dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * [(v^2) / 2] evaluated from 3 to 7.

E(V) = (0.25) * [(7^2 / 2) - (3^2 / 2)].

E(V) = (0.25) * [(49 / 2) - (9 / 2)].

E(V) = (0.25) * (40 / 2).

E(V) = (0.25) * 20.

E(V) = 5.

Therefore, the expected value of the continuous random variable V is 5.

The expected value represents the average value or mean of the random variable V. It is the weighted average of all possible values of V, with each value weighted by its corresponding probability. In this case, the expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

Answer:

Orthogonal.

Step-by-step explanation:

Given:

u = <10, 0>

v = <0, -9>

In unit vector notation, the above vectors can be re-written as:

u = 10i + 0j

v = 0i - 9j

Now, note the following:

(i) two vectors, u and v, are parallel to each other if one is a scalar multiple of the other. i.e

u = kv

or

v = ku

for some nonzero value of a scalar k.

(ii) two vectors are orthogonal if their dot product gives zero. i.e

u . v = 0

Let's use the explanations above to determine whether the given vectors are parallel or orthogonal.

(a) If parallel

u = k v

10i + 0j = k (0i - 9j)   ?

When k = 1, the above equation becomes

10i + 0j  ≠  0i - 9j

When k = 2,

10i + 0j ≠ 2(0i - 9j)

10i + 0j ≠ 0i - 18j

Since we cannot find any value of k for which u = kv or v = ku, then the two vectors are not parallel to each other.

(b) If Orthogonal

u.v = (10i + 0j) . (0i - 9j)  

[multiply the i components together, and add the result to the multiplication of the j components]

u.v = (10i * 0i) + (0j * 9j)

u.v = (0) + (0)

u.v = 0

Since the dot product of the two vectors gave zero, then the two vectors are orthogonal.
