Answer:

Step-by-step explanation:

Mean tells us the average (in this case, total marks/ total number of students).

Standard deviation tells us the spread of a set of data from its mean (how much it deviates from the mean).

Thus, standard deviation can be used to determine the consistency of a data. The smaller the standard deviation, the more consistent the data is.

Since 4S has the smallest standard deviation of 1, it shows the most consistent achievement in the test.

6 ft 2 ft 2 ft 2 ft 10 ft Area: Perimeter:

Pie

Answer:

perimeter: 22ft

area: $480ft^2$ be warned, i dont know if the are is correct but that is what I calculated.

Step-by-step explanation:

The area is measurement of the surface of a shape. To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

Show all the work *10. Find the length of AD

lbvjy [14]

Lines AG and GC are the same.

Angle D is the same on both sides.

This means that line AD and DC are the same.

Set these equal to each other and solve.

2x -3 = x + 2

Add 3 to both sides:

2x = x + 5

Subtract x from both sides:

X = 5

Now you have a value for x, solve for the length.

AD = 2(5)-3 = 10-3 = 7

AD = 7
