Answer:

At least 39200 students.

Step-by-step explanation:

Given that there are 196 countries in the world, and each country would have at least 200 students in a university.

For each country to have at least 200 students in the university, then;

Number of students enrolled in the university = number of required students x number of countries

                                      = 200 x 196

                                      = 39200

At least, 39200 students must be enrolled in the university. Provided that the admission procedures are conditioned for the purpose.

Mashcka [7]

Answer:

The variance of the given data is 106.9667

Step-by-step explanation:

The variance, S² of a sample is given by the expression;

S^2 = \dfrac{\sum \left (x_{i}-\bar{x}  \right )^{2}}{n-1}

Where:

x_{i} = One of the observations

\bar{x} = The mean of the observations

n = Number in the sample = 6

The mean = Σx_{i}/n = (26  + 32 + 29  + 16  + 45  + 19 )/6 = 167/6 = 27.833

Therefore, we have;

S² = ((26 - 27.833)²+(32 - 27.833)²+(29 - 27.833)²+(16 - 27.833)²+(45 - 27.833)²+(19 - 27.833)²)/(6 - 1) = 106.9667.

3x - 12 = 12 - 2x + 6

3x - 12 = 18 - 2x

+2x              + 2x

5x -12 = 18

   + 12   +12

5x = 30

x = 6

the length of marshalls retangular poster is 2 times the width if the perimeter is 24 inches what is the area
Ilia_Sergeevich [38]
Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
   = 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
                                     = 2 * 4 inches
                                     = 8 inches
Now 
The Area of the rectangle = Width * Length
                                          = 4 * 8 inches^2
                                          = 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.
