In each row, the 15 number of the student is arranged. For the given condition, the equal number of the student is to be arranged.

<h3>What is seating arrangement?</h3>

A seating arrangement is an arrangement shows that how the peoples are arranged so that the complete utilization is done.

The given data in the problem is;

The total no of student is 345 students

If the same number of the students are to be arranged for the given row, the following calculation is done;

The numbers of the student in each row is found as;

\rm  n= \frac{Total \ no \ of \ student\ }{Total\ no \of \ rows } \\\\\ n= \frac{345}{23} \\\\ n= 15 \ student

Hence, in each row, the 15 no of the student is arranged.

To learn more about the seating arrangement, refer to the link;

Manuel incorrectly claimed that the surface area of the cylinder shown is about 190.0 in.2. Use a formula to find the surface ar
Kitty [74]

Answer:

25.9%

Step-by-step explanation:

Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose

let the dimension of the cylinder be

radius= 3in

height= 5 in

Step two

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr2

substitute

T. S. A. =2*3.142*3*5+2*3.142*3^2

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

%error= actual -expected/expected*100

%error= 190 -150.816/150.816*100

%error= 39.184/150.816*100

%error= 0.259*100

%error= 25.9%

Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above

erastova [34]

Answer: Min : $750\ ,\ Q_1= \$800\ ,\ Median : \$925\ ,\ Q_3=\$1050\ ,\ Max: \$1100

Step-by-step explanation:

The five -number summary consists of five values :

Minimum value , First quartile (Q_1) , Median , Third Quartile (Q_3)  , Maximum value.

Given : The Insurance Institute for Highway Safety publishes data on the total damage caused by compact automobiles in a series of controlled, low-speed collisions.

The following costs are for a sample of six cars:

$800, $750, $900, $950, $1100, $1050.

Arrange data in increasing order :

$750,$800, $900, $950, $1050, $1100

Minimum value =  $750

Maximum value = $1100

Median = middle most term

Since , total observation is 6 (even) , so Median = Mean of two middle most values ($900 and  $950).

i.e.  Median=\dfrac{900+950}{2}=\$925

First quartile (Q_1) = Median of lower half ($750,$800, $900)

= $800

, Third Quartile (Q_3)  = Median of upper half ($950,  $1050, $1100)

= $1050

Hence, the five-number summary of the total damage suffered for this sample of cars will be :

Min : $750\ ,\ Q_1= \$800\ ,\ Median : \$925\ ,\ Q_3=\$1050\ ,\ Max: \$1100
