In order to get the results shown, the calculations must be done incorrectly. Ordinarily, instructions to round to a particular precision should be applied only to the final result(s). Here, you are expected to round every intermediate result. (This is generally considered to be WRONG!)
The numbers in the column
are simply the squares of the numbers in the column to its left. Round the squares to tenths. Their sum should be the value indicated in the bottom row.
The standard deviation is the square root of the variance,
√(99667.2) ≈ 315.7

Answer:
P(inside larger square and outside smaller) =
Step-by-step explanation:
Probability is the result of the division of the number of possible outcome by the number of an event.
In the question, for a point chosen, the point can be in the small square only or in the area or region between the small square and the big square as such,
Area of larger square = area of region between both squares + area of smaller square
Where the area of a square is S × S where S is the side of a square
Area of larger square = 10 × 10
= 100 cm square
Area of smaller square = 7 × 7
= 49 cm square
Area of the region between both squares
= 100 - 49
= 51 cm square
The probability that a dot selected is inside the larger square and outside the smaller is
P(inside larger square and outside smaller) = Area of region between both square/ Area of larger square
P(inside larger square and outside smaller) =
