Answer:
Expectation number of books a customer will purchase = 1.3
Step-by-step explanation:
x : 0 1 2
p(x) :0.2, 0.3, and 0.5
Expectation
E(X) = ∑x P(x)
= 0 X 0.2 +1 X 0.3+ 2 X 0.5
= 1.3
Expectation E(X) = 1.3
Expectation number of books a customer will purchase = 1.3
Answer:
Hey there!
Velocity is a vector, not a scalar because it also has direction.
Let me know if this helps :)
Answer: Samantha's Recipe:
Ratio of lemonade = 2 1/2 : 6
Caden's Recipe:
Ratio of lemonade = 15 : 32
Step-by-step explanation:
Samantha's Recipe
3 1/2 parts cranapple juice
2 1/2 parts lemonade
Caden's Recipe
4 1/4 parts cranapple juice
3 3/4 parts lemonade
For each recipe, write a ratio that compares the number of parts of lemonade to the total number of parts.
Solution:
For Samantha's Recipe:
Total number of parts = cranapple juice parts + lemonade parts = 3.5 + 2.5 = 6.0
Ratio of lemonade to total number of parts = (2.5)/(6.0) = 2 1/2 : 6
For Caden's Recipe:
Total number of parts = cranapple juice parts + lemonade parts =(17/4)+(15/4) = (32/4) = 8
Therefore, Ratio of lemonade to total number of parts = (15/4) / (8) =(15)/(32) = 15:32
Answer:
12/5
Step-by-step explanation:
SOH-CAH-TOA
SOH - for Sine ratios, Opposite/Hypotenuse
CAH - for Cosine ratios, Adjacent/Hypotenuse
TOA - for Tangent ratios, Opposite/Adjacent
