Answer:
3.5% of 20, (0.035)*20, and 7% of 10
Step-by-step explanation:
Converting the mixed number (3 1/2) to a decimal yields 3.5, so 3.5% of 20 is correct.
3 1/2 is not equal to 3 1/2%, so 3 1/2 * 20 is not correct.
Converting the percentage to a decimal yields .035 which makes .35 too large, so (0.35) * 20 is not correct.
Changing the percentage to a decimal yields .035, so (0.035) * 20 is correct.
If you divide 20 by 2, you get 10, and if you multiply 2 by 3 1/2, you get 7. The 2 remains part of the expression, so it is equal to 3 1/2 of 20.
Answer:
(a) Margin of error ( E) = $2,000 , n = 54
(b) Margin of error ( E) = $1,000 , n = 216
(c) Margin of error ( E) = $500 , n= 864
Step-by-step explanation:
Given -
Standard deviation 
= $7,500
= 1 - confidence interval = 1 - .95 = .05
= 
= 1.96
let sample size is n
(a) Margin of error ( E) = $2,000
Margin of error ( E) = 
E = 
Squaring both side
n = 54.0225
n = 54 ( approximately)
(b) Margin of error ( E) = $1,000
E =
1000 =
Squaring both side
n = 216
(c) Margin of error ( E) = $500
E =
500 =
Squaring both side
n = 864
Answer:
the rise/ run would be 3/3
Step-by-step explanation:
Finance charges on a credit card Include "all of the above".
<u>Option: D</u>
<u>Explanation:</u>
Practically, a finance charge is any expense shown in the borrowing money costs, such as accrued interest and loan fees, including transaction fees. Finance charges are usually synonymous with "interest charges" even though they may contain late fees or other costs in some situations.
With credit cards, the interest that has accrued over the amount one owe throughout that particular billing cycle is an individual's finance fee. For every day of the month, the regular balance approach sums up an individual's financing fee. One need to know the precise credit card balance every day of the billing cycle to do that estimate correctly.
Answer:
a = 6
Step-by-step explanation:
Hello!
Solve:
- 4(3a - 4) = 56
- 3a - 4 = 14 (factoring out 4)
- 3a = 18 (adding 4 to both sides)
- a = 6 (dividing by 3)
Another way:
- 4(3a - 4) = 56
- 12a - 16 = 56 (distributive property)
- 12a = 72 (moving like terms)
- a = 6 (dividing by 12)
Distributive Property of Multiplication:
The process of distributing the outside factor to the terms in the parenthesis.
Example:
