you want 75,000 in your savings account 12 years from now and you are prepared to make equal annaul deposits into the account at the end of the year. if the account pays 6.8 percent interest, what amount must you deposit each year
Answer:
Annual deposit= $3,474.39
Explanation:
Giving the following information:
You want to have $60,000 in your savings account 12 years from now, and you’re prepared to make equal annual deposits into the account at the end of each year. The account pays 6.4 percent interest.
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (60,000*0.064)/[(1.064^12)-1]= $3,474.39

Which of the following is not equivalent to the following expression 2x^2 -16
Answer:
Option C. 2(x + 8)
Step-by-step explanation:
To know which option is the correct answer, let us simplify each expression given in the options to know which will not result to 2x² – 16. This is illustrated below:
For Option A:
2x² + 4x – 4x – 16
= 2x² – 16
For Option B:
2(x² – 8)
Clear bracket
2x² – 16
For Option C:
2(x + 8)
Clear bracket
2x + 8
For Option D:
(4x² – 32) /2
4x²/2 – 32/2
2x² – 16
From the above illustration, option C did not result to 2x² – 16.
Therefore, option C is the answer to the question.

Janice had an unpaid balance of $2358.19 on her credit card statement at the beginning of January. She made a payment of $80.00 during the month, and made purchases of $99.50. If the interest rate on Janice's credit card was 4% per month on the unpaid balance, find her finance charge and the new balance on February1.
Answer:
$2,639.19
Step-by-step explanation:
Her balance at the end of the month is
$2358.19 - $80.00 + $99.50 = $2537.69
So the finance charge is 2537.69 * 0.04% = $101.50
and her new balance is $101.50 + $2537.69 = $2639.19

A recent study investigated whether renowned violinists were able to classify the age of a violin. In the study, violins constructed before 1900 and violins constructed after 2010 were used. The violinists played each violin and were asked to classify the violin as old (constructed before 1900) or new (constructed after 2010). The responses are shown in the following table.
Which of the following statements is supported by the results in the table?
1.)The proportion of all new violins that are correctly classified is equal to the proportion of all old violins that are correctly classified.
2.)The proportion of all new violins that are incorrectly classified is equal to the proportion of all old violins that are correctly classified.
3.)The proportion of all incorrectly classified violins that are old is equal to the proportion of all correctly classified violins that are new.
4.)The proportion of all incorrectly classified violins that are new is equal to the proportion of all correctly classified violins that are new.
5.)The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.
Answer:
The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.
Step-by-step explanation:
According to the table, we have that the correct option is:
5.)The proportion of all correctly classified violins that are old is equal to the proportion of all new violins that are incorrectly classified.
Statement 1:
15 of 33 new are correctly classified, thus, the proportion is:
[tex]p_N = \frac{15}{33} = 0.4545[/tex]
18 out of 31 old, thus:
[tex]p_O = \frac{18}{31} = 0.58[/tex]
Proportions are different, thus, statement 1 is false.
Statement 2:
13 out of 31 old are incorrectly classified, thus:
[tex]p = \frac{13}{31} = 0.4194[/tex]
Different than 0.4545, thus, statement 2 is false.
Statement 3:
Out of 31 incorrectly classified, 13 are old.
Out of 33 correctly classified, 15 are new.
Different proportions, thus, statement 3 is false.
Statement 4:
Out of the 33 new, 15 are correctly classified and 18 incorrectly, different proportions, thus, statement 4 is false.
Statement 5:
18 out of 33 correctly classified are old.
18 out of 33 new violins are incorrectly classified.
Same proportion, thus, statement 5 is true.

Use this expression to name each item. 7m3 + 6r2 – 3r - 8
Answer:
In the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Step-by-step explanation:
We are given the expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
We need to give variable, coefficients and constant.
Variable: The value of variable may change. It can be represented by x, y or any other letter
Coefficients: A numerical or constant quality that is placed with the variable. For example in 4x, 4 is coefficient
Constant: It is fixed value. It cannot be changed.
So, in the given expression [tex]7m^3 + 6r^2 - 3r - 8[/tex]
Variables = m, r
Coefficients = 7, 6 and -3
constant= -8
Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.06 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are less than 9.58? Please do not round your answer.
Answer:
84%
Step-by-step explanation:
The Empirical rule formula states that:
68% of data falls within 1 standard deviations from the mean - between μ – σ and μ + σ
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .
Mean = 8.06
Standard deviation = 1.52
Using the empirical rule, what percentage of American women have shoe sizes that are less than 9.58? Please do not round your answer.
Using the first rule if Empirical formula
68% of data falls within 1 standard deviations from the mean - between μ – σ and μ + σ
μ + σ
= 8.06 + 1.52 = 9.58
This satisfies one side of the distribution, hence:
100 - 68%
= 32%
P(x >9.58) = 32%/2 = 16%
Hence,the percentage of American women have shoe sizes that are less than 9.58 is
P(x < 9.58) = 100 - 16%
= 84 %
Mixed in a drawer are 2 blue socks, 8 white socks, and 6 gray socks. You pull out two socks, one at a time, without looking. Find the probability of getting 2 socks of the same color.
Answer:
6/16
Step-by-step explanation:
Write them out bb wwwwwwww gggggg
there are 16 in total so it would be 6/16 because of each color like bb ww gg thats 6 out of 16
The probability of getting 2 socks of the same color is 1/3.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
In the drawer,
Number of blue socks = 2
Number of white socks = 8
Number of gray socks = 6
Total number of socks = 2 + 8 + 6 = 16
The Total ways to select 2 socks form 16 socks is 120.
The Total ways to select 2 socks of the same color is
T = Possible ways of (2 blue + 2 white +2 gray) socks = 40
The probability of getting 2 socks of the same color is
= 40/120
= 1/3
Therefore, the probability of getting 2 socks of the same color is 1/3.

Segment CD has point E located on it such that CE:ED = 3:5. If the endpoints are located at C(5, -6) and D(11,18) then what are the coordinates of E ?
Answer:
E(29/4,3)
Step-by-step explanation:
Given that,
Segment CD has point E located on it such that CE:ED = 3:5
The coordinates of C and D are (5, -6) and (11,18) respectively.
We need to find the coordinates of E. Let the coordinates are (x,y). Using section formula to find it as follows :
[tex](x,y)=(\dfrac{m_1x_2+m_2x_1}{m_1+m_2},\dfrac{m_1y_2+m_2y_1}{m_1+m_2})\\\\(x,y)=(\dfrac{3(11)+5(5)}{3+5},\dfrac{3(18)+5(-6)}{3+5})\\\\=\dfrac{29}{4},3[/tex]
So, the coordinates of E are (29/4,3).
