U can do tallies.. Its like little lines..That add up to 30.
Answer:
Yes
Step-by-step explanation:
Given that a teacher prepares 26 tiles with 5 vowels numbered 1 and 21 consonants numbered 2.
The probability for drawing vowel =
Prob for consonant =
If number of trials is atleast 30 we can expect reliable results.
Here the results are recorded for 120 times at random.
Since number of trials is large, we can expect a reliable and accurate results representing the actual probability.
This is because more the number of trials, the less would be the margin of error i.edeviationfrom the expected probability would be minimum
Answer:
c = 1.45
Step-by-step explanation:
Solving the equation for c, we find ...
p +e = nc
c = (p +e)/n
Filling in the values given, we have ...
c = (4050 +300)/3000 = 4350/3000 = 1.45
The value of c is 1.45.

<h3>Math Operations</h3>
The four basic math operations are present in your day-to-day life, for example: when you pay your bills. The math operations are:
- addition - represented by symbol "+"
- subtraction - represented by symbol "-"
- multiplication - represented by symbol "x"
- division - represented by symbol "÷"
These symbols, also, are known as arithmetic operators.
Note that in math expressions, it is necessary to apply the rule of operations: parentheses, exponents, multiplication/division, and addition/subtraction.
