Step-by-step explanation:
all points on that line
Answer:
7
Step-by-step explanation:
4 is half of 8 so if s is 4 then the fraction is 8/4. simplified it is 2/1, and that is 2 wholes so 2. the equation rewritten is 9-2 and that = 7.
Step-by-step explanation:
Multiplication......
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
