how do u estimate decimal  like 11.6 and 0.25

Answers

Estimation is about rounding answers to the nearest whole or to a simple fraction.
11.6 is closer to 12 than it is to 11 so we can estimate that
11.6≈12

And .25 is closer to 0 than it is to .5 so we can estimate
.25≈0

It also depends what place we are rounding to, we can say that .25 is close to .3 because we don't want to have a 0 value
.25≈.3
If the number is 0-4 round it down to number that comes before.If the number is 5-9 round it up to the number that comes after.

Help FastWhich of the following is a binomial experiment?
Rolling a six-sided number cube 24 times and recording if a 4 comes up
Rolling a six-sided number cube and recording the number until a 4 comes up
Rolling a six-sided number cube and recording the number until an even number comes up
Rolling a six-sided number cube 24 times and recording the number that comes up

Answers

Answer with explanation:

An experiment is said to be binomial, if it has n number of trials,and out of n trials,when each trial is performed Independently, there are only two possible outcomes,one Success and other will be failure.

In option A,  

Number of trials = 24,which is fixed.

Success= getting 4,when a die is rolled.

Failure = Getting ,number other than,4 , that is , 1,2,3,5,6.

So, This is Binomial Experiment.

In Option B,

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option C

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option D

Number of trials = 24

But, there are more than two possible outcomes.So,this is not a Binomial Experiment.

Correct Option : A

The answer on E2020 is A: Rolling a six-sided number cube 24 times and recording if a 4 comes up.
