Estimation is a process by which we do not exactly do the operation but predicts through pre-known facts and methods in order to determine the required. In this item, we are to predict or estimate the place of the decimal point to the answer when we divide the 42.56, dividend, and 22, our divisor.
We can say that 42 can be divided by 22 only once because twice of 22 is already 44. By this we can say that the decimal place will be after 1. There would only be one digit to the left side of the decimal point.
If we are going to answer the division problem, we get an answer of 1.934545..
This year, John played in 10 baseball games. In these games he had hit the ball 2,3,1,1,3,2,4,6,2, and x times. The mean is 3 hi

Answer:
x = 3
Step-by-step explanation:
The mean is the average so set up an equation that adds up all the points and divides them by the total, set equal to 3, and solve for x
(2+3+1+1+3+2+4+6+2+x)/10 = 3
(24 + x)/10 = 3
24 + x = 30
x = 6
To check if this is correct, add up all the numbers and divide by 10.
2+3+1+1+3+2+4+6+2+6 = 30/10 = 3
In general, a rhombus' diagonals have different lengths. This limits the rotational symmetry order to be 2, namely, it gets back to the same shape by rotating 180 degrees. There is a special kind of rhombus where the diagonals have equal lengths, in which case the rhombus has order of rotational symmetry of four. We also call this special kind of rhombus a square.
