Answer:
Step-by-step explanation:
Adjacent to the undetermined angle is 6, and the hypotenuse has been given. We can conclude, after looking at our SOHCAHTOA, that we will be using cosine(CAH) to solve this problem.
Let the unspecified angle be 
(This sign is called theta, which is just a sign for angle)
Lets start!
cos = adj/hyp
cos = 6/13
= 
(6/13)
= 62.5
= 63

Answer:
eY is positive +0.1 therefore bagels are a normal good.
Step-by-step explanation:
Given data:
when, 10% rise in cheese price, 3% fall in bagels quantity observed
when, 10% rise in income, 1% fall in bagels quantity observed
from formula for cross price elasticity of demand, determine 
As, eAB is negative, bagels $ cream cheese are complements.
By formula for income elasticity of demand,
we find that
Since eYis positive, bagels are a normal good.
Answer:
6536.25
Step-by-step explanation:
Given that :
Number of friends = 4
Cost of movie ticket = 725 each
At concession stand:
Pop corn = 850
Number of popcorn = 2
Large soda = 575
Number of large sodas = 3
Discount given = 15%
Amount spent on movie ticket :
725 * 5 = 3625
Amount spent at concession stand :
Cost of popcorn + cost of large soda
(850 * 2) + (575 * 3) = 3425
15% discount on purchase :
Discount = ((1-0.15) * 3425) = 2911.25
Total amount spent :
3625 + 2911.25
= 6536.25
Answer: D. Simple Random Sampling
Step-by-step explanation: When selection is made or based on chance which is equal or the same for all members within a population. In the scenario described above, there is no prior shuffling, arrangement or segregation of members within the population into groups or subgroups, rather the interviewed voters were chosen at random directly from within the larger population based on equal chance. Therefore voters already have their numbers, then using a random number generator, voters whose number corresponds were interviewed is a clear scenario of simple Random Sampling.
