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:
11. 135 mph
12. 40 Oz
13. 50 m
14. 2500
15. 240
i don't know 16
Step-by-step explanation:
11. 27 x 5= 135 mph
12. 24 : 6 x 10= 40 Oz
13. 1.5 : 3 x 100= 50 m
14. 40% = 1000
10% = 250 (1000 : 4 = 250)
100%= 2500 (250 x 10 = 2500)
15. 75% -> 25% = : 3
180 : 3 = 60
180 + 60 = 240
20 because 10+10=20 and 20+20=40 and 20+40=60
Quadrants 2 and 4 because in quadrant 2, cosine is negative and sin is positive, while in quadrant 4, cosine is positive and sin is negative
