Answer:
<em> 4/12 and 6/18</em>
Step-by-step explanation:
Given the fraction 2/6
We are to write 2 different equivalent fractions that are the same as 2/6
To do this, we will multiply the numerator and denominator of the fraction by same constant. Multiply the numerator and denominator by 2 will give;
2/6 * 2/2
= (2*2)/(6*2)
= 4/12
Also multiplying by a value of 3
= 2/6 * 3/3
= (2*3)/(6*3)
= 6/18
<em>Hence the 2 different equivalent fractions are 4/12 and 6/18</em>
The probability of the sample is 0.5 or 50%
<u>Explanation:</u>
Given:
Mean, μ = 20
Standard deviation, δ = 1.3
Probability of sample being less than 20.1 = ?
P (x < 20.1) = 20.1 - μ / δ √n
P (x < 20.1) = 
= 0.0098
P( x < 20.1) = P(z < 0.0098)
P (z < 0.0098) = 0.5
The value of P is found out using a z score table.
Therefore, probability of the sample is 0.5 or 50%
