Answer:
The correct answer is D. 1/√3
Step-by-step explanation:
The ratio of the opposite side and the adjacent side to the given angle is the tangent.
According to the image below formula is:
tangent(α)=a/b
a= oppositive side: the side in front of the given angle.
b= adjacent side: the side next to the given angle.
α= the given angle.
According to the image, the value of “a” is 1 and there is √3 for “b”.
So, the correct answer is D. 1/√3

Answer:
$1,304.70
Step-by-step explanation:
If interest 6% annually, monthly is 0.5%.
The debt in 5 months will be 800 plus compounded interest for 5 months plus new due debt
In 3 more months the debt will be 2220.201 plus compounded interest for 3 months minus payment
After 8 months the debt would be 1253.67 plus compounded interest for 8 months
Then the size of the final payment would be $1,304.70
Answer:
Standard error of mean = 689
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $28,520
Standard Deviation, σ = $5600
Mean of sampling distribution =
As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.
Sample size, n = 66
Since the sample size is large, we can use normal distribution for approximation.
Standard error of mean =
