The question is incomplete. The complete question is

A teacher promised a movie day to the class that did better, on average, on their test. The box plot shown in the below-mentioned figure shows the results of the test.

Which class should get the reward, and why?

- The 2nd-period class should get the reward. They have the highest score, a perfect 100.

- The 2nd-period class should get the reward. They have a higher median.

- The 4th-period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd-period class.

- The 4th-period class should get the reward. Their lowest score is an outlier and should be thrown out.

The box plot shown in the question provides the information that
In 2nd period the minimum of the data is 77, first quartile is 78, median of the data is 89, third quartile is 92 and the maximum of the data is 100.
Hence, the mean of the results of 2nd period is

\frac{77+78+89+92+100}{5}=87.2

In 2nd period the minimum of the data is 72, first quartile is 83, median of the data is 89, third quartile is 96 and the maximum of the data is 98.

Hence, the mean of the results of the 4th period is

\frac{72+83+89+96+98}{5}=87.6

Hence, obviously, the 4th period is having more mean.

Moreover, we can observe that if more of the marks are on the higher side the average will automatically be more. Hence, as the first and the third quartiles are more on the 4th-period, so the average marks for the 4th period must be better.

So, just by observing the box plot, we can give the statement that  "The 4th-period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd-period class. "

Therefore, the 4th-period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd-period class.

C) Bhurashi can do 1/3 part of a work in 6 days.
Simora [160]

Answer:

<h2>i. 18 days</h2><h2>ii.\frac{1}{18} part of work</h2><h2>iii. \frac{1}{2} part of work</h2><h2 />

Step-by-step explanation:

i.

\frac{1}{3} part of work can be done in 6 days.

Days taken to complete the whole work:

= 6 * 3

= 18 days

ii. Whole work will be done in 18 days.

So, 1 day work = \frac{1}{18}

iii. Work done in 9 days :

\frac{1}{18}  \times 9

=  \frac{1}{2}

So, remaining work :

1 -  \frac{1}{2}

=  \frac{1 \times 2 - 1}{2}

=  \frac{2 - 1}{2}

=  \frac{1}{2} part of work

Hope this helps...

Good luck on your assignment..

What si another way to write the number 75?
kakasveta [241]

Answer:

7.5\text{x}10^{1}

Step by step explanation:

We have been given a number 75 and we are supposed to rewrite it using a different way. Since the given number has been written in standard notation, we can write it using scientific notation.

We know that we can write a standard number in scientific notation by moving the decimal point to the left or right and making corresponding changes to the exponent of 10. In this case, we will move the decimal point to the left by one place and raise the exponent of 10 by 1. Therefore, we get the required number in a different notation (scientific notation) as 7.5\text{x}10^{1}.
