Step-by-step explanation:

The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.

(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.

(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.

Answer:

Step-by-step explanation:

Given that:

Principal = $650

Interest rate, r = 2.3% = 0.023 compounded daily

Time, t it takes for final amount, A to reach $880

Using the relation :

A = P(1 + r/n)^nt

n = number of times compounded per period

Hence, n = 365

880 = 650(1 + 0.023/365)^365t

880/650 = 1.0000630^365t

1.3538461 = 1.0000630^365t

Take the log

0.1315692 = 0.0000273596 * 365t

0.1315692 = 0.0099862t

Step-by-step explanation:

To determine the probabilities, we need to use the standard normal distribution table or a calculator that has this function. The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

(a) P(−0.79 ≤ z ≤ −0.57) = We need to find the area under the standard normal distribution curve between z = -0.79 and z = -0.57. Using a standard normal distribution table or calculator, we find this probability to be 0.0767.
(b) P(z > 1) = We need to find the area under the standard normal distribution curve to the right of z = 1. Using a standard normal distribution table or calculator, we find this probability to be 0.1587.

(c) P(z ≥ −3.36) = We need to find the area under the standard normal distribution curve to the right of z = -3.36 (or the area to the left of z = 3.36, which is the same thing since the standard normal distribution is symmetrical). Using a standard normal distribution table or calculator, we find this probability to be 1.

(d) P(z < 4.96) = We need to find the area under the standard normal distribution curve to the left of z = 4.96. Since this value is greater than any z-score on the standard normal distribution table, we can say that this probability is extremely close to 1 (or practically 1).


To find the probabilities for a standard normal distribution, you can use a z-table or an online calculator based on the given intervals, rounding to four decimal places:

(a) P(-0.79 ≤ z ≤ -0.57) = P(z ≤ -0.57) - P(z ≤ -0.79) = 0.2843 - 0.2148 = 0.0695
(b) P(z > 1) = 1 - P(z ≤ 1) = 1 - 0.8413 = 0.1587
(c) P(z ≥ -3.36) = 1 - P(z < -3.36) = 1 - 0.0004 = 0.9996
(d) P(z < 4.96) = 0.9999 (since the probability of z > 4.96 is extremely small)

Answer:

300

Step-by-step explanation:

375 divided by 5=75

Each “1”=75

4x75=300

There are 300 boys.

Hope this makes sense

Answer:

300 boys

Step-by-step explanation:

Let the number of boys = x

Girls: 375

boys : girls = 4 : 5

total in the ratio is 9

girls are 5/9 of total, and are 375

boys are 4/9 of total

5/9 x = 375

x = 375 × 9/5

x = 675

Boys are 4/9 of total.

4/9 × 675 = 300

If the correlation coefficient is equal to 0.50, the value of r-square is equal to 0.25.

The correlation coefficient, also known as Pearson's correlation coefficient (r), is a measure of the strength and direction of the linear relationship between two variables. The coefficient ranges from -1 to 1, with 0 indicating no correlation.

To calculate the coefficient of determination (R-squared or R²), you need to square the correlation coefficient (r). In this case, the correlation coefficient (r) is equal to 0.50.

Here's a step-by-step explanation of how to calculate R-squared:

1. Determine the correlation coefficient (r), which is given as 0.50.
2. Square the correlation coefficient: R² = r².
3. In this case, R² = (0.50)².

Calculating the R² value, we get:
R² = 0.25

R-square is a statistical measure that is used to determine how well the regression model fits the data. It is also called the coefficient of determination. The value of R-square ranges from 0 to 1, with 1 indicating a perfect fit and 0 indicating no relationship between the variables. R-square is an important measure because it helps to evaluate the accuracy of the model and determine how well it predicts the outcome.

So, when the correlation coefficient is equal to 0.50, the R-squared value is equal to 0.25. The R-squared value represents the proportion of the variance in one variable that is predictable from the other variable. In this case, 25% of the variance in one variable can be explained by the linear relationship with the other variable.

For the mathematical series, the total of the first 25 terms is 1850.

Arithmetic progression or arithmetic sequence is a numerical series in which the difference between subsequent terms is constant. For example, the sequence 5, 7, 9, 11, 13, 15.. An arithmetic sequence is a series of integers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6. An arithmetic progression is another name for an arithmetic sequence.

Here,

This is an arithmetic sequence as each term has a common difference to the previous term.  Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number.

We know that a=2 and d=(20-14)=(14-8)=(8-2)=6 so

a(25)=2+6(25-1)

a(25)=146  

The sum of an arithmetic sequence is the average of the first and last terms times the number of terms, in this case:

s(25)=25(2+146)/2

s(25)=1850

The sum of the first 25 terms is 1850 for the arithmetic sequence.

Answer:

The slopes of DE and BC are the same:  0.5.  The two lines are therefore parallel.

Step-by-step explanation:

See the attached graph, made in DESMOS.

The midpoints D and E may be determined by taking the average values of x and y that form the endpoints of lines AB (midpoint D) and AC (midpoint E):

Midpoint   Endpoint1 Endpoint 2  Midpoint

  D                A(4,6)         B(2,-2)          D(3,2)   [(4+2)/2 =3 and (6-2)/2 = 2]

  E                 A(4,6)         C(-2,-4)         E(1,1)     [(4-2)/2 =1 and (6-4)/2 = 1]

If DE is parallel to BC,  both lines must have the same slope.  Find the slopes for DE and BC by calculating the Rise/Run (the change in y over the cahnge in x):

Slope of DE:   Rise = (2-1) = 1,  Run = (3-1) = 2.  Slope = (1/2) or 0.5

Slope of BC:   Rise = (-2-(-4)) = 2,  Run = (2-(-2)) = 4.  Slope = (1/2) or 0.5

The slopes of DE and BC are the same:  0.5.  The two lines are therefore parallel.

The correct answer for the Estimate at Completion (EAC) based on the given information is not among the provided options. The calculated EAC = $319,772.19.

Given the following information calculate the EAC and select from the list below. The project is planned for 12 months PV $30000 EV $26000 AC$29000 BAC $252000.The correct answer is option A) $293,023.25.

What is EAC? EAC (Estimate at Completion) refers to the total expected cost of the project. EAC includes the actual cost incurred to date as well as the expected cost required to complete the remaining project work.

The formula for EAC is as follows:

EAC = AC + (BAC - EV) / (CPI * SPI)

EAC= Estimated Cost at Completion, BAC= Budget at Completion, AC= Actual Cost, CPI= Cost Performance Index, SPI= Schedule Performance Index, EV= Earned Value, and PV= Planned Value.

Given, PV (Planned Value) = $30000EV, (Earned Value) = $26000, AC (Actual Cost) = $29000, BAC (Budget at Completion) = $252000.

Now, calculate CPI and SPI.

CPI (Cost Performance Index) = EV / AC = 26000 / 29000 = 0.8965SPI

(Schedule Performance Index) = EV / PV = 26000 / 30000 = 0.8667

Calculate EAC using the following formula:

EAC = AC + [(BAC - EV) / (CPI * SPI)]EAC = 29000 + [(252000 - 26000) / (0.8965 * 0.8667)]

EAC = 29000 + [226000 / 0.7773]

EAC = 29000 + 290772.19

EAC = $319,772.19

The transformation of System A into System B is:

Equation [A2]+ Equation [A 1] → Equation [B 1]"

The correct answer choice is option D

How can we transform System A into System B?

To transform System A into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

System A:

-3x + 4y = -23 [A1]

7x - 2y = -5 [A2]

Multiply equation [A2] by 2

14x - 4y = -10

Add the equation to equation [A1]

14x - 4y = -10

-3x + 4y = -23 [A1]

11x = -33 [B1]

Multiply equation [A2] by 1

7x - 2y = -5 ....[B2]

So therefore, it can be deduced from the step-by-step explanation above that System A is ultimately transformed into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

If we put all of it together we have the factors 2 x 3 x 3 x 5 x 7 = 630. It can also be written in exponential form as 21 x 32 x 51 x 71.

Step-by-step explanation:

Prime factorization expresses an integer in terms of multiples of prime numbers. The prime factorization of the integer 630 is 2×3×3×5×7

Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.

For an integer, factorization is decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number. Those composing integers are called factors of that considered integers.

Prime factorization is when all those factors are prime numbers.

Thus, prime factorization expresses an integer in terms of multiples of prime numbers.

Prime factorization is unique for each integer.

Example: 18=2×3×3

The number 630 can be written as:

\(630 = 63 \times 10\\630 = (7 \times 9) \times 2 \times 5\\630 = (7 \times (3 \times 3) ) \times 2 \times 5\\630 = 2 \times 3 \times 3 \times 5 \times 7\)

(2,3,5,7 are all prime numbers, so this is prime factorization of 630. Ordering of multiple doesn't matter because of commutative property of multiplication)

Thus, the prime factorization of the integer 630 is 2×3×3×5×7
