Answer:
Step-by-step explanation:
3+6+x+4+3=94
16+x=94
x=78
The mode is 4
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

we know that
Two angles are supplementary if their sum is equal to degrees
in this problem we have
so
therefore
<u>the answer is</u>
The two angles are supplementary
For transaction 3 it should be -155.15 and for transaction 4 it would be -223.75
