Therefore, to determine the direct sum S ⊕ S' with orthogonality, you need to ensure that every vector in S is orthogonal to every vector in S', and vice versa. If this condition holds true, you can conclude that S ⊕ S' is an orthogonal direct sum.

The orthogonal complement of a subspace is a concept in linear algebra that represents the set of all vectors in the vector space that are orthogonal (perpendicular) to every vector in the given subspace. To find the direct sum S ⊕ S' of two subspaces S and S', the subspaces S and S' must be orthogonal to each other. In other words, every vector in S must be orthogonal to every vector in S', and vice versa.

The value of the equation x² - x + 3 is 37/9.

We have,

We can start by multiplying both sides of the equation by x:

2x - 3/x = x + 1

2x - 3 = x^2 + x

Rearranging and simplifying, we get:

x^2 - x + 3 = (2x - 3) + x^2

x^2 - x + 3 = x^2 + 2x - 3

-x + 3 = 2x - 3

5 = 3x

x = 5/3

Now we can substitute x into the equation x^2 - x + 3:

x^2 - x + 3 = (5/3)^2 - 5/3 + 3

x^2 - x + 3 = 25/9 - 15/9 + 27/9

x^2 - x + 3 = 37/9

Therefore,

The value of x² - x + 3 is 37/9.

The area of the rectangle is increasing at a rate of 27,900,000 meters³ per year when the width of the region is 450 meters.

The inner-city revitalization region is a rectangle that is twice as long as it is wide. At a time when the area is 450 meters wide, the width of the region is increasing at a rate of 31 meters per year. The aim is to find out how quickly the area is changing at this point in time. The area of the rectangle is given by the formula,

Area = length × width

Given that the width of the rectangle is increasing at a rate of 31 meters per year. Let's say the width of the rectangle is w meters, and the rate of change in width is dw/dt meters per year. Then, we can say, dw/dt = 31 meters per year

Width of the rectangle is w meters

Length of the rectangle is twice the width, or 2w meters

Area of the rectangle is given by the formula, A = lw= 2w × w= 2w²

Now, we need to find dA/dt, the rate at which the area of the rectangle is changing with respect to time (t).We can find it using the formula,

dA/dt = dA/dw × dw/dt

dA/dw = 4w (differentiate 2w² with respect to w)

dw/dt = 31 meters per yeard

A/dt = dA/dw × dw/dt= 4w × 31= 124w meters² per year

From the given information, the width of the rectangle is 450 meters wide. So, the width is w = 450 meters.

dA/dt = 124w meters² per year

= 124 × 450 meters² per year

= 27,900,000 meters³ per year

Which is the increasing rate of the rectangle.

Since the Reticulated Python is the biggest living snake, the Titanoboa is believed to have been 44 feet long, or more than twice as long.

The measurement or size of something from one end to the other is referred to as its length. To put it another way, it is the bigger of the higher two or three dimensions of a geometric form or object. For instance, the length and width of a parallelogram define its measurements.

If the Titanoboa was 2 1/5 times as long as the Reticulated Python, we can express this relationship as a ratio:

Titanoboa length / Reticulated Python length = 2 1/5

To solve for the Titanoboa length, we can first convert the mixed number 2 1/5 to an improper fraction:

2 1/5 = 11/5

Substituting this value into the equation above, we get:

Titanoboa length / 20 feet = 11/5

To solve for the Titanoboa length, we can cross-multiply and simplify:

Titanoboa length = (20 feet) x (11/5) = 44 feet

Therefore, the Titanoboa is estimated to have been 44 feet long, which is more than twice as long as the largest living snake, the Reticulated Python.

The probability of getting a head and a number greater than 5 i.e, independent events is 0.0833.

A coin is tossed and a die is rolled. These are two independent events. Two events are defined as independent if the outcome of one event has no effect on the outcome of another event. The probability is calculated by multiplying two independent probabilities together, i.e, P(A and B) = P(A) x P(B)

We have, Let us assume two independent events be ,

A : A coin is tossed and the head is thrown.

B : A die is rolled, and a number greater than 5 occurs.

Total possible outcomes when a coin tossed = 2 ={ H ,T }

Total possible outcomes when a die rolled = 6 = { 1,2,3,4,5,6} .

We have to determine probability of getting a head and a number greater

than 5.

Probability of getting the head on toss a coin, P(A) = 1/2

Probability of occuring a number greater than 5 on rolling a die = P(B) = 1/6

So, the probability of getting a head on coin and a number greater than 5 on die =P(A)×P(B)

=(1/2)× 1/6 = 1/12=0.0833

Hence, required probability is 0.0833.

True, the standard deviation is a resistant measure of spread.

The standard deviation is calculated as the square root of the variance of the data set. Variance is calculated as the average of the squared differences between each data point and the mean of the data set. The standard deviation is the square root of this average.

In mathematical terms, the standard deviation can be calculated using the following formula:

σ = √(1/n ∑(x - μ)²)

Where σ is the standard deviation, n is the number of data points in the data set, x is the value of the i-th data point, and μ is the mean of the data set.

The standard deviation is an important measure because it gives an idea of how much the individual values in a data set differ from the mean.

In summary, the standard deviation is a resistant measure of spread because it gives a robust measure of the spread of the data in a set and is not easily influenced by outliers or extreme values.

It can be 99% confident that the true average amount of time it takes to repair the second kind of machine failure is within the range of -16.2 to 1.0 minutes longer than the first kind.

We have to give that,

A study of two kinds of machine failures shows that 58 failures of the first kind took on average 79.7 minutes to repair with a sample standard deviation of 18.4 minutes.

And, 71 failures of the second kind took on average 87.3 minutes to repair with a sample standard deviation of 19.5 minutes.

Let's denote the average repair time for the first kind of machine failure as μ₁ and the average repair time for the second kind as μ₂.

Here, For the first kind of machine failure:

n₁ = 58,

x₁ = 79.7 minutes,  

s₁ = 18.4 minutes.

For the second kind of machine failure:

n₂ = 71,

x₂ = 87.3 minutes,

s₂ = 19.5 minutes.

Now, calculate the 99% confidence interval using the following formula:

CI = (x₁ - x₂) ± t(critical) × √(s₁²/n₁ + s₂²/n₂)

For a 99% confidence level, the Z-score is , 2.576.

So, plug the values and calculate the confidence interval:

CI = (79.7 - 87.3) ± 2.576 × √((18.4²/58) + (19.5²/71))

CI = (- 16.2, 1) minutes

So, It can be 99% confident that the true average amount of time it takes to repair the second kind of machine failure is within the range of -16.2 to 1.0 minutes longer than the first kind.
