I think that options include:
A. With a high level of confidence, the republican defeated the democrats
B. the republican definitely defeated the democrats
C. the republican defeated the democrats with probability of 0.60
D. It is not possible to predict the winner because less than 1% of the voters were in the sample
Answer: Option D
Step-by-step explanation:
The result of this election cannot be predicted accurately as only 1000 voters out of 3,000,000 were sampled.
To get a good sample, the sample must be at least 10% of the total population and be a representative of the population but in this context, the sample is even less than 1% (30,000). Thus, the prediction might be inaccurate...
To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.

Answer: Hence, this investment would be worth of $366.756
Step-by-step explanation:
Since we have given that
Amount he invests = $350
Rate of interest compounded quarterly = 1.5%
Number of years = 50 years = 1.25 quarters
As we know the formula for "Compound Interest ":
For remaining half year, we first find the interest with using the above amount as principal amount.
Hence, this investment would be worth of
Answer:
No solution.
Step-by-step explanation:
When two lines have the same slope but different y-intercepts, they are parallel. Parallel lines never intersect, and therefore there is no solution.
