The best description of the distribution is bimodal with a gap.

Here in the plot, we can see that there are two peaks and it implies that there are two modes.

This can be seen in a histogram as a distinct gap between two cohesive groups of bars. When two clearly separate groups are visible in a histogram, you have a bimodal distribution. Literally, a bimodal distribution has two modes, or two distinct clusters of data

We can see that there is a gap between the two modes. So the best description of the distribution is bimodal with a gap.

The space of continuous functions on [0, 1] equipped with L²-norm 1/3 || f || = (S²151³) ¹/³ is also complete.

To determine if the space of continuous functions on [0, 1] equipped with L²-norm 1/3 || f || = (S²151³) ¹/³ is complete, we need to check if every Cauchy sequence in this space converges to a function in the same space.

Let {f_n} be a Cauchy sequence in the space of continuous functions on [0, 1] with respect to the given norm. Then, for any ε > 0, there exists an integer N such that for all m,n ≥ N, we have:

1/3 || f_m - f_n || < ε

Since this norm is equivalent to the standard L²-norm on [0, 1], it follows that {f_n} is also a Cauchy sequence in the space of continuous functions on [0, 1] equipped with the standard L²-norm.

Now, since the space of continuous functions on [0, 1] equipped with the standard L²-norm is complete, there exists a continuous function f on [0, 1] such that f_n → f in the L²-norm as n → ∞. Moreover, by the equivalence of norms, we know that f_n → f with respect to the given norm as well.

Therefore, the space of continuous functions on [0, 1] equipped with L²-norm 1/3 || f || = (S²151³) ¹/³ is also complete.

The resulting graph of g(x)=|x|+5 is a V-shaped curve that is shifted upwards by 5 units.

What is function ?

Function can be defined in which it relates an input to output.

To graph the function g(x)=|x|+5, we start with the parent function f(x)=|x|.

First, we shift the entire graph of f(x) upwards by 5 units to get g(x). This means that the new function will take the absolute value of x and then add 5 to it.

To graph g(x), we can choose two points on either side of the y-axis and then plot the corresponding points. We can use the ray tool to draw the rays passing through these points.

Here are the steps to graph g(x)=|x|+5:

Choose a value of x on the left side of the y-axis, such as x=-3.

Substitute this value into the equation g(x)=|x|+5 to get g(-3)=|-3|+5=8. This gives us the point (-3,8).

Choose another value of x on the left side of the y-axis, such as x=-2.

Substitute this value into the equation g(x)=|x|+5 to get g(-2)=|-2|+5=7. This gives us the point (-2,7).

Draw a ray passing through the points (-3,8) and (-2,7) to represent the left side of the graph.

Choose a value of x on the right side of the y-axis, such as x=2.

Substitute this value into the equation g(x)=|x|+5 to get g(2)=|2|+5=7. This gives us the point (2,7).

Choose another value of x on the right side of the y-axis, such as x=3.

Substitute this value into the equation g(x)=|x|+5 to get g(3)=|3|+5=8. This gives us the point (3,8).

Draw a ray passing through the points (2,7) and (3,8) to represent the right side of the graph.

Therefore, The resulting graph of g(x)=|x|+5 is a V-shaped curve that is shifted upwards by 5 units.

The reduced row echelon form of the \(4\)×\(5\) matrix is

What is reduced row echelon form ?

When all of a matrix's pivots equal 1, and the pivots are the only non-zero elements in the fundamental columns, we say that the matrix is in reduced row echelon form.

Given that \(a_{1} ,a_{2}\) and \(a_{3}\) will be the independent vector, lets select them as the basis vector.

\(a_{1} =\left[\begin{array}{c}1&0&0\\0\end{array}\right]\) , \(a_{0} =\left[\begin{array}{c}0&1&0\\0\end{array}\right]\)

\(a_{3}= a_{1} +5a_{2}\)

   = \(\left[\begin{array}{c}1&0&0\\0\end{array}\right]+5\left[\begin{array}{c}0&1&0\\0\end{array}\right]\)

  =\(\left[\begin{array}{c}1&5&0\\0\end{array}\right]\)

\(a_{4}\) = \(\left[\begin{array}{c}0&0&0\\1\end{array}\right]\) and

\(a_{5} = -3a_{1} -a_{2} +4a_{4}\)

  =  \(\left[\begin{array}{c}-3&-1&0\\4\end{array}\right]\)

Hence the \(4\)×\(5\) matrix will be in the form

\(\left[\begin{array}{ccccc}1&0&1&0&-3\\0&1&5&0&-1\\0&0&0&0&0\\ 0&0&0&1&4\end{array}\right]\)

Since the one complete row is already zero, hence for calculating the row reduced echelon form we just need to replace the 3rd and 4th row.

It will take 120 minutes for smaller hose to fill the complete swimming pool on its own.

Let us represent the complete swimming pool as 1. Now, total time required to fill the swimming pool is 40 hours. So, amount of swimming pool filled in 1 minute = 1/40

Similarly, amount fo swimming pool filled by larger hose in 1 minute = 1/60

Now for the smaller hose, the amount of swimming pool filled in 1 minute = 1/40 - 1/60

The amount of swimming pool filled in 1 minute = (60 - 40)/2400

The amount of swimming pool filled in 1 minute = 20/2400

The amount of swimming pool filled in 1 minute = 1/120

Total time taken to fill swimming pool = 1 ÷ (1/120)

Total time taken to fill swimming pool = 120 minutes

Answer:

D.   -6

Difference between two terms are -6.

The system of inequalities is 6.50x + 10y ≥ 1100 and x + y ≤ 140.

The graph is attached below

To plot the system of equations, we can first plot the lines for each equation on the same coordinate plane.

The first inequality is 6.50x + 10y ≥ 1100.

We can rewrite this in slope-intercept form as

y = (-6.50/10)x + (1100/10).

The slope of the line is -6.50/10 = -0.65

And the y-intercept is (1100/10) = 110.

The second inequality is x + y ≤ 140.

We can rewrite this in slope-intercept form as y = (-1/1)x + (140/1).

The slope of the line is -1/1 = -1

And the y-intercept is (140/1) = 140.

We can now plot these lines on the same coordinate plane.

The points of intersection are the solutions to the system of equations.

According to the given standard deviation, the bag that the student brought has more than 1 gram of potato chip than the average chip bag.

Standard deviation:

Standard deviation refers the measure of how scattered the data is in relation to the mean.

Given,

The student wanted to know if the bags of potato chips they were buying contained the correct weight of chips compared to the listed weight on the bag of 42.5 grams.

And the student collected a sample of 30 bags of chips and weighed each bag. Here the average weight of the bags they collected was 41 grams with a standard deviation of 1.6 grams. assume a 95% level of confidence.

Now, we have to find the confidence interval for this situation.

From, the given details, we have obtained the following things,

Bag weight = 42.5 gram

Number of samples = 30

Average weight = 41 grams

Standard deviation = 1.6 grams

Confidence level = 95%

So, according to the formula of confidence interval,

The value of it is calculated as,

=> CI = x ±  Z × s / √n

When we apply the values on the formula, then we get,

=> CI = 41 ± 1.9600 × 1.6 / √30

=> CI = 41 ± 0.573

Therefore, Confidence Interval 41 ±0.573 (±1.4%) [40.427 – 41.573].

While we compare this one with the given bag weight we get the difference of,

=> 42.5 - 41.5

=> 1

Therefore, the bag that the student brought has more than 1 gram of potato chip than the average chip bag.

rs - s^2 = 12 --(2)

sub (1) into (2):

(5 + s/2)s - s^2 = 12

5s + 0.5s^2 - s^2 = 12

-0.5s^2 + 5s - 12 = 0

s^2 - 10s + 24 = 0

The percentage of Japanese-Americans under 35 in Santa Clara County, CA is approximately 11.3%.

Santa Clara County, CA is home to approximately 27,873 Japanese-Americans. To determine what percentage of this population is under age 35, it is necessary to first calculate the total number of Japanese-Americans under 35. To do this, we can subtract the estimated number of Japanese-Americans over age 35 from the total population of Japanese-Americans. We can then divide this number by the total population of Japanese-Americans to find the percentage of Japanese-Americans under age 35. In Santa Clara County, CA, the estimated number of Japanese-Americans over age 35 is 24,672, and the total population of Japanese-Americans is 27,873. Subtracting 24,672 from 27,873 yields 3,201 Japanese-Americans under age 35. We can then divide 3,201 by 27,873 to get a percentage of 11.3%. Therefore, approximately 11.3% of the Japanese-American population in Santa Clara County, CA is under age 35.
