Answer:
Step-by-step explanation:
From the information on 60 students we write frequency distribution as
x 1 2 3 4 5 6 7 total
f 13 22 15 6 3 0 1 60
C 13 35 50 56 59 59 60
xf 13 44 45 24 15 0 7 148
x^2f 13 88 135 96 75 0 49 456
Mean = 2.67
Var = 445.92
Std dev = 21.21
I quartile = 2
III quartile = 3
20% have atmost 1
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.
The ten thousand value in 8920000 is 20000
The values that will round up to 20000 is any value between 15000 (inclusive) and 20000 (not inclusive)
The values that will round down to 20000 is any value between 20000 (inclusive) to 25000 (not inclusive)
For example, 16752 will round up to 20000 to the nearest ten thousand
Another example, 21251 will round down to 20000 to the nearest ten thousand.
