1.) It typically takes teachers 9 minutes longer than students to get ready for school. - The median of two data = Teachers 25 - Students 16: typically, teachers take 25 mins to get ready and students take 16 mins to get ready.

2.) Both of the means are correct, but the reasoning is incorrect. - the mean absolute deviation for team A is 2 and for team B is 0.8. Greater mean does not signify higher mean absolute deviation.

3.) The students tend to have fewer siblings than the teachers. - the teachers have a wide range of data and they have more siblings than the students so the first choice is the better option.

4.) between 120 and 153 mph in race A; between 125 and 145 mph in race B - get the data from the lower whisker till the median.

Japan was ready to surrenderThe atomic bomb was a terrible weapon that would bring great death and destruction to JapanThe united state could make Japan fear the atomic bomb's power without killing anyone

Explanation:

The use of atomic bomb on the cities of Hiroshima and Nagasaki in Japan left the cities greatly destroyed and alot of lives were lost. this attack was carried out on these cities on the 6th and 9th of August 1945 with the approval of the United Kingdom according to the Quebec agreement.

The detonation of the atomic bombs by the U.S on Japanese cities has been the first and only time an atomic bomb has been used in an armed conflict this operation was carried out in the final year of the world war II and this led to Japan surrendering its mainland prior to the planned invasion of Japan by the allied forces. the people who opposed to the use of atomic bomb on Japan felt that Japan would have surrendered without the use of atomic bombs on their cities and also the effect of atomic bomb would be devastating as well to both civilians and the Military.

1) Original piece of paper size is 8 inches by 10 inches 

Initial area  = 8x10 = 80 sq. inches 

# of times cut                 #of pieces         Area of each piece   (sq. inches)

1                                           2                                  40     

2                                           4                                  20

3                                           8                                  10

4                                          16                                  5

.                                           .                                     .

n                                          2^n                              80/(2^n)

This means on cutting n number of times, the number of pieces = 2^n

Area of each piece = 80/(2^n)    sq. inches 

2)

Here we are cutting the paper into pieces. The total area remains constant. Therefore, the product of the number of pieces and the area of each piece will remain the same (80 sq. inches). The above table shows that the product of the 2nd and 3rd columns always remain the same.

4, 8, 16,64 and 4096.

Step-by-step explanation:

We are already given: 4096=2^{12}

To determine other whole numbers that can be raised to a power to obtain 4096, we apply the product rule of indices.

Product Rule of Indices: a^{xy}=(a^x)^y

Now 12 can be factored in the following ways where one of the terms must be a perfect square:

12=2 X 612 =6 X 212 =3 X 412 =4 X 312=1 X 12

2^{12}=(2^2)^6=4^6\\\\2^{12}=(2^6)^2=64^2\\\\2^{12}=(2^4)^3=16^3\\\\2^{12}=(2^3)^4=(8^2)^2=8^{2*2}=8^4\\\\2^{12}=(2^{12})^1=4096^1 $(This is the trivial case)

Therefore, the other whole numbers that can be raised tp a power to obtain 4096 are: 4, 8, 16, 64 and 4096.

If you want to show your supervisor that you are ready for more responsibility I suggest taking more initiative at work - sometimes doing additional tasks without being asked to do so. Since taking responsibility can also mean more work, this would show your supervisor that you're ready for this.

Ordered pairs are in the form (x, y), meaning your first number is your x-value and your second number is your y-value.

An ordered-pair solution to the equation y = -5x - 4 would mean that if you plug in the x-value into the variable, x in the equation, you should get your y-value when you solve for the variable y. (You can also plug in the y-value and do it that way, but for this problem, it's easier to plug in the x-value!)

Now you just have to go through your answers and plug them in. The ordered-pair that does not give a correct y-value when the x-value is plugged in is your
A) (10, -52), x = 10, y = -52
y = -5x - 4\\
y = -5(10) - 4\\
y = -54
Since y = -54 and not -52, the ordered pair (10, -52) is not a solution!

B) (7, -39), x = 7, y = -39
y = -5x - 4\\
y = -5(7) - 4\\
y = -39
Since y = -39, this ordered pair is a solution.

C) (-7, 31), x = -7, y = 31
y = -5x - 4\\
y = -5(-7) - 4\\ 
y = 31
Since y = 31, this ordered pair is a solution.

D)  (8, -44), x = 8, y = -44
y = -5x - 4\\ 
y = -5(8) - 4\\ 
y = -44
Since y = -44, this ordered pair is a solution

A) (10, -52) is not a solution
