Answer:

Step-by-step explanation:
We are given the equation 0.003 * 1.25 and are asked to solve it and convert it into scientific notation.
We need to first solve it:


Now convert it into scientific notation, if there are numbers before the decimal point, it is a positive exponent, visa versa:

Answer:
Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
The range is calculated by subtracting the lowest value from the highest value.

The arrangement of mother's eye level, ground level and playground forms a right angles triangle.
The legs of this triangle are 12.6 m (eye level to ground) and 20 m (building to playground).
Using trigonometry and assuming the depression angle is Ф;
tan Ф = 20/12.6 = 1.5873
Ф = tan ^-1(1.5873) = 57.78°
