The level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.
Volume of the spherical tank
The volume of the spherical tank is calculated by using the following formula as shown below;
[tex]V = \frac{4}{3} \pi r^3= \frac{4}{3} \pi (\frac{d}{2} )^3= \frac{4}{3} \pi \frac{d^3}{8} = \frac{1}{6} \pi d^3[/tex]
The depth of the tank at different capacity levelThe level lines on the tank showing the depths of different capacities is calculated as follows;
[tex](\frac{1}{6} \pi d^3 )k = V\\\\k = \frac{V}{d^3} \\\\\frac{V_1}{d_1^3} = \frac{V_2}{d_2^3}\\\\d_2 = \sqrt[3]{\frac{V_2d_1^3}{V_1} }\\\\for \ 10,000 \ L\\\\d_2 = \sqrt[3]{\frac{10,000\times 4^3}{33,500} }\\\\d_2 = 2.65 \ m\\\\for \ 20,000 L\\\\d_3 = \sqrt[3]{\frac{20,000\times 4^3}{33,500} }\\\\d_3 = 3.36\ m\\\\d_4 = \sqrt[3]{\frac{30,000\times 4^3}{33,500} }\\\\d_4 = 3.85 \ m[/tex]
Thus, the level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m
Given data :
Diameter of tank ( d ) = 4 m
1 cm³ = 1000 l
Volume of a spherical tank
The volume of a spherical tank can be calculated as
V = [tex]\frac{4}{3}\pi r^3 = \frac{1}{6}\pi d^3[/tex]
Next step : calculate the level lines at various capacities
applying equation above
V = [tex](\frac{1}{6} \pi d^3)k[/tex]
where k = v / d³
therefore : di = [tex]\sqrt[3]{\frac{Vid^3}{V_{1} } }[/tex] ------- ( 1 )
where : di = level line , Vi = volume of tank , V1 = capacity of tank = 33500
d = diameter of tank
Applying equation ( 1 )
For Vi = 10000 llevel line ( di ) = 2.65 m
For Vi = 20000 llevel line ( di ) = 3.36 m
For Vi = 30000 llevel line ( di ) = 3.85 m
Hence we can conclude that The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

Referring to figure 1, explain the process illustrated between step 1 and step 2.
The process illustrated is the elongation of an amino acid chain.
What does the figure illustrate?Step 1. This figure shows the process of synthesis of an amino acid change, which occurs in the ribosome. In this, you can observe two transfer RNA attached to one aminoacid chain represented by the letters.Step 2. This figure shows the two aminoacid chains that have joined to create one unique amino acid chain, due to this, one of the transfer RNA is now free.How does this occur?This is possible due to translation elongation. In this process, amino acids are bound together by pairing up two transfer RNA. Moreover, this requires an elongation factor that makes it possible to add aminoacids to a chain and therefore make the chain longer.

Consider a disk that rotates at 3600 rpm. The seek time to move the head between adjacent tracks is 2 ms. There are 32 sectors per track, which are stored in linear order from sector 0 through sector 31. The head sees the sectors in ascending order. Assume the read/write head is positioned at the start of sector 1 on track 8. There is a main memory buffer large enough to hold an entire track. Data is transferred between disk locations by reading from the source track into the main memory buffer and then writing the data from the buffer to the target track. A. How long will it take to transfer sector 1 on track 8 to sector 1 on track 9? b. How long will it take to transfer all the sectors of track 8 to the corresponding sectors of track 9?.
Answer:
19.71 ms
Explanation:
The disk rotates at 3600 rpm, hence the time for one revolution = 60 / 3600 rpm = 16.67 ms.
Hence time to read or write on a sector = time for one revolution / number of sectors per track = 16.67 ms / 32 sectors = 0.52 ms
Head movement time from track 8 to track 9 = seek time = 2 ms
rotation time to head up sector 1 on track 8 to sector 1 on track 9 = 16.67 * 31/32 = 16.15 ms
The total time = sector read time +head movement time + rotational delay + sector write time = 0.52 ms + 2 ms + 16.15 ms + 0.52 ms = 19.19 ms

Out of five men and five women, we form a committee consisting of four different people. Assuming that each committee of size four is equally likely, find the probabilities of the following events:.
The probabilities of the following events are 10/21, 11/42,41/42, and 2/15 respectively
How to find probabilitiesProbability of forming a committee consisting of two men and two women = (5C2 × 5C2) / 10C4
5C2 = 5! / 2!(5 - 2)!
= 5! / 2!3!
= 5×4× / 2×1
= 20/2
= 10
So,
(5C2 × 5C2) / 10C4
= 10×10 / 210
= 100/210
= 10/21
Probability of forming a committee consisting of two men and two women = 10/21
Probability of forming a committee that has more women than men. This means forming a committee that has 4 women, 0 men or 3 women 1 man
= {(5C3 × 5C1) + (5C4 × 5C0)} / 10C4
= {(10×5) + (5×1)} / 210
= (50 + 5) / 210
= 55/210
= 11/42
Probability of forming a committee that has at least one man. This means the committee must not have all women as members
= 1 - 5C4/10C4
= 1 - 5/210
= 1 - 1/42
= 41/42
Probability of forming a committee with both Alice and Bob are members of the committee. This means there are only two more people to join the committee from the remaining 8 people.
= 8C2 / 10C4
= 28/210
= 2/15
The complete question:
1. The committee consists of two men and two women.
2. The committee has more women than men.
3. The committee has at least one man. For the remainder of the problem, assume that Alice and Bob are among the ten people being considered.

Select the statements that would allow you to conclude that the relationship between a response variable y and an explanatory variable x is linear.
Here are the statements that would allow you to conclude that the relationship between a response variable y and an explanatory variable x is linear:
- The graph of y versus x shows the points lying approximately along a straight line.
- The correlation coefficient r between x and y is close to +1 or -1.
- The regression equation relating y to x is of the form y = bx + a, where b and a are constants.
- The residuals (differences between observed and predicted values of y) show no systematic pattern when plotted against x.
- An F-test or t-test on the regression model gives a statistically significant result for the coefficient of x.
- Adding higher order terms of x (like x^2, x^3 etc) to the regression equation does not significantly improve the model fit.
- There are no statistical interactions detected between x and other explanatory variables when modeling y.
In summary, signs of a linear relationship include a straight line pattern in the data plot, a high correlation coefficient, a significant linear regression model, random residuals, and lack of improvement by adding nonlinear terms or interactions. These indicators would allow you to conclude that the relationship between y and x is best described by a linear model.
During aerobic respiration electrons travel in which sequence.
Answer:

Explanation:
A factory manager selected a random sample of parts produced on an old assembly line and a random sample of parts produced on a new assembly line. The difference between the sample proportion of defective parts made on the old assembly line and the sample proportion of defective parts made on the new assembly line (old minus new) was 0. 6. Under the assumption that all conditions for inference were met, a hypothesis test was conducted with the alternative hypothesis being the proportion of defective parts made on the old assembly line is greater than that of the new assembly line. The p-value of the test was 0. 18.
Considering the p-value of the test, it is found that there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.
What are the hypothesis tested?At the null hypothesis, it is tested that the proportion of defective parts made on the old assembly line is not greater than that of the new assembly line, that is:
[tex]H_0: p_O = p_N[/tex]
At the alternative hypothesis, it is tested if the proportion is greater, that is:
[tex]H_1: p_O > p_N[/tex]
What is the decision?The p-value is greater than the standard significance level of 0.05, hence we do not reject the null hypothesis, that is, there is not enough evidence to conclude that the proportion of defective parts made on the old assembly line is greater than that of the new assembly line.
