if s1 and s2 are subspaces of rn of the same dimension, then s1 = s2.

Answers

Answer 1

This statement is false. Two subspaces of R^n can have the same dimension but still be different.

Here are a few bullet points that elaborate on this:

A subspace is a subset of a vector space that is closed under addition and scalar multiplication.The dimension of a subspace is the number of vectors in a basis for the subspace.Two subspaces of R^n can have the same dimension if they have the same number of vectors in a basis, but the vectors themselves could be different.For example, the subspace of all multiples of the vector (1,0) and the subspace of all multiples of the vector (0,1) both have dimension 1, but they are different subspaces because they contain different sets of vectors.The subspace of all multiples of the vector (1,0) is the set of all vectors of the form (x,0) and the subspace of all multiples of the vector (0,1) is the set of all vectors of the form (0,y) and these two sets are different.

Therefore, the statement "If s1 and s2 are subspaces of R^n of the same dimension, then s1 = s2" is not true in general.

7×4×z = 2× 5 (move the denominator of both fractions to the other side)

Answer: The answer your looking for is 5/14

Step-by-step explanation: You want to leave the variable alone, so you divide both sides by 4/5. If you divide 2/7 by 4/5, you get 5/14.

Which statement about the slope of the line is true?

The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.
The slope from point O to point A is four times the slope of the line from point A to point B.
It is fraction negative 1 over 4 throughout the line.
It is −4 throughout the line.

Both triangles are along the slope of the line, so the slope for both triangles are the same.

Using two points on the slope you find that the slope is -1/4

The speed of the current in the river is 4 mph about travel 17 miles downstream with the current in the this river in the same time that it travels 9 miles upstream against the current find the speed of the boat in the Stillwater

Answers

Answer:

Step-by-step explanation:

b = speed of boat in still water

traveling downstream, the boat goes (b+4 miles)/hour.

traveling upstream the boat goes (b-4 miles)/hour.

Time to travel 17 miles downstream = 17 miles × (1 hour)/(b+4 miles)

Time to travel 9 miles upstream = 9 miles × (1 hour)/(b-4 miles)

17 miles × (1 hour)/(b+4 miles) = 9 miles × (1 hour)/(b-4 miles)

17/(b+4) = 9/(b-4)

cross-multiply denominators:

17(b-4) = 9(b+4)

17b - 68 = 9b + 36

8b = 104

b = 13 miles per hour

La mediana es 79 la moda es 87 la media 87 y él rango es 26

Step-by-step explanation:

Espero te ayude ;)

The mode, median and the range are 87, 79 and 26 respectively

Given the data 84,91, 72,68,87, 78,65,87,79., we are to get the median, mode, and range of the data.

The mode is the number that occurs the most from the given data. Since 87 occurs twice, hence the mode is 87

The median is the number in the middle after arrangement. On arranging, we will have:

65, 68, 72, 78), 79, (84, 87, 87, 91

From the data, we can see that the median value is 79

Range  = Highest - lowest

Range = 91 - 65

Range = 26

Hence the range of the data is 26

The following probabilities are based on data collected from U.S. adults. Individuals are placed into a weight category based on weight, height, gender and age.

Underweight Healthy Weight Overweight (not Obese) Obese
Probability 0.017 0.377 0.343 0.263

Based on this data, what is the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) range?

Answers

Answer:

the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394

Step-by-step explanation:

  Given the data in the question;

                Underweight   Healthy Weight    Overweight (not Obese)    Obese

Probability       0.017              0.377                        0.343                          0.263

so

P( underweight) = 0.017

P( Healthy Weight) = 0.377

P( Overweight (not Obese) ) = 0.343

P( Obese ) = 0.263

now, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) range will be;

P( weigh less than overweight(but not obese) =  P( underweight) + P( Healthy Weight)

P( weigh less than overweight(but not obese) = 0.017 +  0.377

P( weigh less than overweight(but not obese) = 0.394

Therefore, the probability that a randomly selected U.S. adult weighs less than the overweight(but not obese) is 0.394

Answers

Answer:

Follows are the solution to this question:

Step-by-step explanation:

[tex]Frequency\ total = 155 + 256 + 144 + 145 = 700;[/tex]

In point (1):

Now that it is possible to obtain the joint distribution as:

[tex]Yes \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{155}{700} = 0.2214\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{256}{700} = 0.3657 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.5871\\\\No \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{145}{700} = 0.2071\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \frac{144}{700} = 0.2057\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.4128\\\\Total \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.4285 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.5714\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1[/tex]

In point (2):

Likely that now It (the IT column total throughout the table above) seems to be the random individual selected = 0.4285;

Here, 0.4285 is the necessary probability.

In point (3):

The way of its worker's sleep at work =0.5871 ( first row total in the above table )

Here 0.5871 was its required probability.

In point (4):

In this as employee slept at work, he is likely to also be from IT to be calculated with:

[tex]=\frac{\text{probability he was just an IT-former but was asleep at work}}{ \text{possibly he worked at work}}\\\\=\frac{0.2214}{0.5871} \\\\ =0.3771 \text{was its probability required here}.[/tex]

In point (5):

In an individual is also an official government, its chance of getting sleep at work is measured when:

[tex]= \frac{\text{Probability he is professional in business slept at work}}{\text{or that he is officially in business}} \\\\= \frac{0.3657}{0.5714}\\\\ = 0.6400 \text{is the required probability here}.[/tex]

In point (6):

[tex]\to P(IT) \ P(Yes) = 0.4285 \times 0.5871 = 0.2516 \\\\\to P(IT and Yes ) = 0.2214 \\\\[/tex]

Therefore, 2 cases aren't independent, because P(IT) P(Yes) is not the same as P(IT and Yes), which also implies that P(IT|Yes) is not the same as P (IT), therefore "[tex]\text{No because P("IT " | "Yes")} \neq P("IT")[/tex]" is correct.
