Explanation:
The magic square is a n×n square which contains different number and sum of all the number of any row or column gives same value.
in any magic square the sum values of all row or column is three time of the number in centre of the square.
in above magic square the middle number is 2/6
so we can calculate the final value by multiplying with 3,
[tex] \frac{2}{6} \times 3 = \frac{2}{ \cancel6}_2 \times \cancel3 = \cancel{\frac{2}{2}} = 1[/tex]
The magic number or sum of any row or column is 1,
using this we can find the missing,
in column first,
1/6 and 1/3 are given and middle term is missing
let the middle term be x now,
[tex]x + \frac{1}{6} + \frac{1}{3} = 1 \\ x = 1 - \frac{1}{6} - \frac{1}{3} \\ x = 1 - ( \frac{3 + 6}{18}) \\ x = 1 - \frac{9}{18} \\ x = \frac{18 - 9}{18} \\ x = \cancel \frac{9}{18} = \frac{1}{2} [/tex]
similarly we can solve for the 3rd fraction of second column,
let the third number be y,
[tex] \frac{3}{ 6} + \frac{2}{6} + y = 1 \\ y = 1 - \frac{3}{ 6} - \frac{2}{6} \\ y = 1 - \frac{5}{6} = \frac{1}{6} [/tex]
Now in first and third row, the third number is missing which can be calculated in same way.
The rough work and final calculation is attached!

-1,1,4,81-2,2-1,6-2,10-2=-1,1,4,8 is my answerA bouncy ball is dropped from a height of 16ft and always rebounds of the distance of the previous fall.
What distance does it rebound the 5th time?
What is the total distance the ball has travelled after this time?
Draw a picture to represent the bouncing ball.
Answers
The bouncy ball follows a geometric sequence or pattern
The distance of rebound the 5th time is 0.015625 ftThe total distance the ball has travelled after this time is 5.328125 feetThe distance of rebound the 5th timeThe given parameters are:
Initial height, a = 16 ftRebound rate = 0.25The distance at rebound n is represented as:
Hn = a * r^n
At the 5th time, we have:
H5 = 16 * 0.25^5
Evaluate
H5 = 0.015625
Hence, the distance of rebound the 5th time is 0.015625 ft
The total distance travelledTo do this, we calculate H1 to H5
So, we have:
H1 = 16 * 0.25^1 = 4
H2 = 16 * 0.25^2 = 1
H3 = 16 * 0.25^3 = 0.25
H4 = 16 * 0.25^4 = 0.0625
H5 = 0.015625
Add this distances
Total = 4 + 1 + 0.25 + 0.0625 + 0.015625
Total = 5.328125
Hence, the total distance the ball has travelled after this time is 5.328125

A certain gas has a volume of 10 liters at a temperature of 404 kelvins (k) and a pressure of 36 pascals (pa). if the temperature is raised to 450 k and the pressure is raised to 40 pa, what is its volume? to the nearest liter, the volume is liters.
Answers
The final volume of the ideal gas is 10.02 liters.
Given Initial volume V₁=10 liters
Initial temperature T₁=404K
Initial pressure P₁ = 36 pascals
Final volume = V₂
Final temperature T₂ = 450K
Final pressure P₂ =40 pascals
What is the ideal gas equation?The ideal gas equation with usual notations is given by:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
So, [tex]\frac{36*10}{404} =\frac{40*V_2}{450}[/tex]
[tex]V_2=[/tex]10.02 liters

The local amusement park is a popular fleld trip destination. This year the senior class at the High
School planned their senior class trip there. The school had to take 24 total vehides between vans
Vand buses. There are 752 total students in the senior class. Each van holds 8 students and each
bus can hold 43 students. How many vans and buses did they have to take?
Answers
Answer:
8 vans16 busesStep-by-step explanation:
The given relations can be written as two equations in two unknowns. These can be solved by any of the ususal methods.
__
SetupLet v and b represent the numbers of vans and buses used, respectively.
v + b = 24 . . . . . 24 vehicles were taken
8v +43b = 752 . . . . 752 students were transported
__
SolutionPerhaps the easiest solution is that afforded by a graphing calculator. It shows the solution to be ...
v = 8 . . . . vans required
b = 16 . . . . buses required
__
You can eliminate the v variable by subtracting 8 times the first equation from the second.
(8v +43b) -8(v +b) = (752) -8(24)
35b = 560 . . . . . simplify
b = 16 . . . . . . divide by 35
v = 24 -16 = 8 . . . . . find v from the first equation
They had to take 8 vans and 16 buses.

Therefore:

Sum of the first 6 terms → n= 6:
[tex]\begin{aligned}S_6 & =\dfrac{324-324(\frac16)^6}{1-\frac16}\\ & =\dfrac{324-\frac{1}{144}}{1-\frac16}\\ & =\dfrac{9331}{24}\\ & = 388.79\:\textsf{(nearest hundredth)}\end{aligned}[/tex]

The value of z-score with a confidence level of 95% in finding margin of error for the mean of a normally distributed population from a sample is 1.96.
What is normally distributed data?Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data.The standard deviation of the data is the half of the difference of the highest value and mean of the data set.The confidence level is 95% when finding the margin of error for the mean of a normally distributed population from a sample.
The critical z score value for the confidence level of 95% is 1.96 and +1.96 standard deviation.
