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

Answer:
97°
Step-by-step explanation:
The sides that are equal are 4.6
One of the sides length is 4.6, and its opposite angle is 97. If there is another line that has a length of 4.6 in the same figure, it's angles should also be 97 degrees.
Answer:
50ºF
Step-by-step explanation:
(10°C × 9/5) + 32 = 50°F
