Answer:
The value of the CD at the end of the 4 years is $5,808.86.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Howard invested $5,000 in Certificate of Deposit (CD) that pays 3.75% interest.
This means that 
Compounded weekly
An year has 52 weeks, so 
Then
What is the value of the CD at the end of the 4 years?
This is A(4). So
The value of the CD at the end of the 4 years is $5,808.86.
Answer:
The p value would be given by this probability:
Since the p value is a very small value at any significance level used we can reject the null hypothesis and we can conclude that the true mean for this case is different from 124 ft
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
z would represent the statistic (variable of interest)
represent the p value
Hypothesis to test
We want to check the following system of hypothesis:
Null hypothesis: 
Alternative hypothesis :
The statistic is given by:
(1)
Replacing the info given we got:
The p value would be given by this probability:
Since the p value is a very small value at any significance level used we can reject the null hypothesis and we can conclude that the true mean for this case is different from 124 ft
In order to write the given number in Scientific Notation we have to move the decimal digit 10 places to the right.
Moving decimal to the right means, the exponent of 10 will be negative when the number is written in scientific notation.
Since, we have to move the decimal by 10 digits, the exponent of 10 will be -10.
Therefore, the number written in scientific notation will be:
The answer is 108 as your surface area.
Work:
To find surface area, you find the area of each side and add it all together. For the bottom and the top sides, it’s 6 x 3 which equals to 18. 18 + 18 = 36. Then, 3 x 4 = 12. 12 + 12 = 24. 6 x 4 = 24. 24 + 24 = 48. Then, you add it all together which equals to 108. If what I did doesn’t makes sense, I’ll explain it more detailed here.
So, I found the area of the bottom side and multiplied it by 2 to represent the top and bottom sides. Then, I did the same thing for the other sides if that makes sense. I’m really sorry if I’m not explaining it well. I’m better at doing the work in my head and not on paper or explaining it to other people.
Anyway, hope this helps!
