Answer:
Step-by-step explanation:
82.1 = 82 1/10 (thats 82 and 1/10) or 821/10 (if you dont want a mixed number)
7.3 = 7 3/10 or 73/10
9.3 = 9 3/10 or 93/10
if there is 1 number to the right of the decimal, put that number over 10....not the whole number, just the number to the right of the decimal. Leave the number to the left of the decimal alone.
if there were 2 numbers to the right of the decimal, then put those two numbers over 100.
example :
3.43 = 3 43/100
2.76 = 2 76/100
if there were 3 numbers to the right of the decimal, put those 3 numbers over 1000
example :
2.347 = 2 347/1000
3.679 = 3 679/1000
you understand ?
The probability would be out of 100,
in this case if it refers to the data from 2009 it would be 39:61
Answer:
y
2
Step-by-step explanation:
1. switch sides
2. distribute
3. simply (combine like terms) in this case it would go to 22y
4. add 48 to both sides
5. simplify
6. divide
y2
Answer:
The sum of the probabilities is greater than 100%; and the distribution is too uniform to be a normal distribution.
Step-by-step explanation:
The sum of the probabilities of a distribution should be 100%. When you add the probabilities of this distribution together, you have
22+24+21+26+28 = 46+21+26+28 = 67+26+28 = 93+28 = 121
This is more than 100%, which is a flaw with the results.
A normal distribution is a bell-shaped distribution. Graphing the probabilities for this distribution, we would have a bar up to 22; a bar to 24; a bar to 21; a bar to 26; and bar to 28.
The bars would not create a bell-shaped curve; thus this is not a normal distribution.
