What is the use of mathematics in cricket.?
Mathematics play an important role in cricket.I think most mathematics is used in cricket only.It is used to calculate the over rate (total number of overs bowled by a bowling side in one hour) by dividing the number of time with the overs.It is also used to find the run rate of the bowler (total number of runs conceded by a bowler per one over of his career) by dividing the number of runs with the number of overs.It is also used to calculate the average and strike rate of both bowlers and batsmen.Batsman strike rate is the number of runs a batsman has made per 100 balls of his career and average is the number of runs a batsman has made getting out once i.e. number of runs/number of times a batsman has got out.Strike rate of the bowler is the number of balls a bowler has taken to get a wicket i.e. the number of balls/number of wickets and average of a bowler is the number of runs the bowler has given per wicket i.e. the number of runs/numbers of wickets.
You toss the same coin five times how would you classify the events?
The answer depends on what you are looking for: the full sequence of results, the number of heads (or tails) the number of runs, the lengths of runs, or whatever.

Where does 0.101 go on a number line?
Assuming the number line runs from 0 to 1, the number 0.101 will be 101/1000 of the way across - this is just a little further on from one tenth.
Number of runs a pitcher gives up per 9 innings?
ERA
How do you find an ERA?
You multiply the number of runs the pitcher has given up by the number of innings in the game then divide it by the number of innings the pitcher has pitched
How can you make your ERA go down?
Pitch more shutout innings - that is, innings where you don't give up an earned run. ERA is calculated by taking the number of earned runs a pitcher gives up, dividing it by the number of innings he/she pitched, then multiplying the result by nine. So, for example, if a pitcher has six complete innings and gives up two earned runs, their ERA becomes three (2 divided by 6 is 1/3, 1/3 multiplied by nine is 3). This works over the course of a pitcher's career, so if a pitcher gives up six earned runs over six innings in one game, his/her ERA becomes nine. If he/she then pitches a complete game shutout (nine full innings, no earned runs) their ERA drops to 3.6 (as it is now six earned runs from fifteen innings).
How do you figure out a pitchers ERA?
ERA is based on 9 innings pitched. When you see a pitcher with a 4.94 ERA that means for every 9 innings pitched, he gives up 4.94 earned runs. Example: A pitcher has pitched 150 innings and given up 60 earned runs. 1) Divide the number of earned runs (60) by the number of innings pitched (150) =0.40. 2) Then take that number (0.4) and multiply it by 9 =3.60. A pitcher who has pitched 150 innings and given up 60 earned runs has an ERA of 3.60.
How do you calculate a pitchers era?
A pitcher's era (earned run average) is calculated as follows: 1. Number of Earned Runs 2. Times 9 3. Divided by number of innings pitched So, if a pitcher gives up 3 earned runs in 5 innings then we first multiply 3 times 9 = 27. Then we take 27 and divide it by 5 (for innings pitched) to get an era of 5.4. Also, an earned run is a run that scores without the defense creating any errors.
How many runs does a pitcher allows over 9 innings?
there is no set amount
What is an ERA in softball?
ERA is Earned Run Average. An earned run is a run that is scored by a batter that reached base while a pitcher was on the mound, so long as the batter did not reach base on an error. Example A: If Pitcher A gives up a a single, then a home run, Pitcher A acquired 2 earned runs. Example B: If Pitcher B gives up a ground ball to the second basemen who mishandles the ball allowing the runner to reach first, and then Pitcher A gives up a home run, only 1 earned run is acquired. Example C: Pitcher C gives up a single and then is is yanked from the game. Pitcher D comes in for relief and gives up a home run. Pitcher C acquires 1 earned run for the runner on first, and Pitcher D acquires an earned run for the batter that hit the home run. Earned Run Average is calculated by determining how many earned runs a pitcher averages over nine innings. Each full inning is counted as one. If a starting pitcher is pulled from the mound with one out in the seventh inning, he pitched 6 full innings plus one third of an inning = 6 1/3 innings (this is written 6.1 innings). Lets say he gave up 4 earned runs this outing: Take 4 earned runs and divide by 6 1/3 innings and multiply by 9 innings in a game = an ERA of 5.68. Over the course of a season the numbers will get larger. In 2002, Greg Maddux gave up 58 earned runs while pitching 199.1 innings. Take 58 earned runs and divide by 199 1/3 and then multiply by 9 innings in a game = 2.62 ERA.
Does ERA change if you play 7 innings?
ERA stands for Earned Run Average. The number of innings per game determines how ERA is calcuated. In Major League Baseball they play 9 innings so ERA is calculated with this equation, Earned Runs divided by 9. High School baseball (at least where I am located) plays 7 innings as a regulation length game. In this case a pitcher's ERA is Earned Runs divided by 7. In Little League the a regulation game is 6 innings, so ERA would be determined by Earned Runs divided by 6. If you are playing a game and it goes in to extra innings then a pitcher's ERA is not affected by the extra innings. If a regulation game is 6 innings, and the game goes into the seventh inning, then a pitcher's ERA is still determined by # of earned runs divided by 6. In summary ERA is ALWAYS determined by the amount of Earned Runs allowed divided by the number of innings played (not including extra innings).
What does the abbreviation era stand for in baseball?
The ERA in baseball stands for Earned Run Average which is the average amount of runs given up by a pitcher per game. For example a 1.98 ERA is amazing but a 6.10 ERA is terrible. The lower your ERA the better.
What does Earned Run Average mean as in baseball?
It is a measure to judge how effective a pitcher is. It calculated by taking the total earned runs a pitcher has allowed and dividing by (total #of innings pitched/9). Giving you an average number of runs a pitcher allows (earned runs) every 9 innings
