Answer:
Step-by-step explanation:
An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point. Here is an irrational number: π = 3.141592
First, you need to multiply 2*21cm, which gives us 42 cm.
Then we multiply it by π, or 22/7 in this case, and 22/7*42cm gives us 132 cm.
So the answer is: 132cm.

I think x=23 because it looks like on the smaller triangle everything is divided by 3 and 23-10=13
Using the conditions for the binomial distribution, it is found that it is a binomial variable, thus, the correct option is:
Yes. All four conditions are met.
---------------------------------------
For a variable to be classified as binomial, four conditions have to be met.
- For each trial, there can be only two possible outcomes.
- There is a fixed number of trials.
- Trials are independent.
- In each trial, the probability of a success and a failure has to be the same.
In this problem, the random variable is the number of spelling errors, which is a binomial variable, as:
- There are 250 words, thus the number of trials is fixed.
- For each word, either there is a spelling error or not, thus two possible outcomes.
- The probability of a word being misspelled is independent of any other word, that is, the probability of an spelling error is the same.
Thus, the correct option is:
Yes. All four conditions are met.

30% is equal to 0.3 (found by dividing the percentage by 100). Then we multiply the cost of dinner, $85, by 0.3 to find an answer of $25.50.
Answer: $25.50
