63 mod 17 = 12, the solutions are all integers congruent to 12 modulo 17, such as 12, 29, and -5.

The given equation is 2x = 7 (mod 17).

9 is an inverse of 2 modulo 17.

Multiplying both sides of the equation by 9, we get x = 9.7 (mod 17).

Since 63 mod 17 = 12, the solutions are all integers congruent to 12 modulo 17, such as 12, 29, and -5.

Correct order:

The given equation is 2x = 7 (mod 17).

9 is an inverse of 2 modulo 17.

Multiplying both sides of the equation by 9, we get x = 9.7 (mod 17).

Roman has a certain amount of money. if he spends 15, then he has 14 of the original amount left. Roman had originally 20.

To find out how much money Roman had originally, you can follow these steps:
Step 1: Let the original amount of money be "x".
Step 2: According to the problem, if Roman spends $15, he has 1/4 of the original amount left.

So, after spending 15, he has (1/4)x left.
Step 3: Since he spent $15, we can write the equation as: x - 15 = (1/4)x.
Step 4: To solve for x, first multiply both sides of the equation by 4 to get rid of the fraction:

4(x - 15) = 4(1/4)x => 4x - 60 = x.
Step 5: Subtract "x" from both sides:

4x - x - 60 = 0 => 3x - 60 = 0.
Step 6: Add 60 to both sides:

3x = 60.
Step 7: Divide both sides by 3 to find the value of x:

x = 60 / 3 => x = 20.

Lucy has $7 less than Kristine and $5 more than Nina together, the three have $35. Lucy has $11.

Let's denote the amount of money that Kristine has as K, the amount of money that Lucy has as L, and the amount of money that Nina has as N.

According to the given information, we can form two equations:

Lucy has $7 less than Kristine: L = K - 7

Lucy has $5 more than Nina: L = N + 5

We also know that the three of them have a total of $35: K + L + N = 35

We can solve this system of equations to find the values of K, L, and N.

Substituting equation 1 into equation 3, we get:

K + (K - 7) + N = 35

2K - 7 + N = 35

Substituting equation 2 into the above equation, we get:

2K - 7 + (L - 5) = 35

2K + L - 12 = 35

Since Lucy has $7 less than Kristine (equation 1), we can substitute K - 7 for L in the above equation:

2K + (K - 7) - 12 = 35

3K - 19 = 35

Adding 19 to both sides:

3K = 54

Dividing both sides by 3:

K = 18

Now we can substitute the value of K into equation 1 to find L:

L = K - 7

L = 18 - 7

L = 11

Finally, we can find the value of N by substituting the values of K and L into equation 3:

K + L + N = 35

18 + 11 + N = 35

N = 35 - 18 - 11

N = 6

Therefore, Lucy has $11.

the probability of randomly selecting the correct unscrambling would be 1/n!. As the length of the word increases, the probability of randomly selecting the correct unscrambling becomes increasingly small due to the exponential growth of possible arrangements.

The probability of coming up with the correct unscrambling through random letter selection depends on the specific word being unscrambled and the number of possible permutations. In general, the probability can be quite low due to the large number of possible combinations.

To calculate the probability, you would need to know the total number of possible letter arrangements and the number of arrangements that result in the correct unscrambling. Let's assume we have a word with n letters. The total number of possible arrangements is n!, which represents n factorial (the product of all positive integers from 1 to n).

The number of arrangements that result in the correct unscrambling depends on the specific word and the length of the word. For example, if the word has 4 letters, there are 24 possible arrangements (4!). However, only one of those arrangements is the correct unscrambling.

The statement "Exactly 50% of the area under the normal curve lies to the left of the mean" is a true statement.

In a normal distribution, the mean, median, and mode all coincide, and the distribution is symmetrical.

The mean is the balance point of the distribution, with 50% of the area to the left and 50% to the right of it. Exactly 50% of the area under the normal curve lies to the left of the mean.

This implies that the distribution is symmetrical, and the mean, mode, and median are the same.

Step-by-step explanation:

To add fractions, we want to make sure there is a common denominator. After that, we can add the numerator.

\(\frac{8}{z^2+6z+9} +\frac{5}{z^2-9}\)                 [factor denominator]

\(\frac{8}{(z+3)(z+3)} +\frac{5}{(z+3)(z-3)}\)      [multiply first fractioni by z-3 and second by z+3]

\(\frac{8(z-3)}{(z+3)^2(z-3)} +\frac{5(z+3)}{(z+3)^2(z-3)}\)   [distribute by FOIL]

\(\frac{8z-24}{(z+3)^2(z-3)} +\frac{5z+15}{(z+3)^2(z-3)}\)   [add]

\(\frac{13x-9}{(z+3)^2(z-3)}\)

This is the same as A. Therefore, A is our answer.

The given series Σ (2n^2+1)/(3n^5+ 2n +1) converges by the integral test.

To apply the integral test, we need to verify that the series is positive, continuous, and decreasing for all n ≥ 1.

For n ≥ 1, we have:

(2n^2+1)/(3n^5+ 2n +1) > (2n^2)/(3n^5+ 2n +1) = (2/n^3)/(3 + 2/n^2 +1/n^5)

Since the denominator is increasing as n increases, the denominator is greater than or equal to 6 for all n ≥ 1. Therefore,

(2/n^3)/(3 + 2/n^2 +1/n^5) < (2/n^3)/6 = 1/3n^3

So, for n ≥ 1, we have

(2n^2+1)/(3n^5+ 2n +1) < 1/3n^3

Since the series Σ 1/3n^3 is a convergent p-series (with p = 3 > 1), the given series satisfies the conditions of the integral test, and therefore converges.

To confirm that the series is decreasing, we can take the derivative of the function f(x) = (2x^2+1)/(3x^5+ 2x +1) and show that it is negative for all x ≥ 1. However, this derivative is quite complicated, so we will not pursue this approach further.

Answer:

The last year value of the house will be $230,000.

Step-by-step explanation:

GIVEN: Decrease in house price = 20%

            Current house price = $184,000

TO FIND: Value of the house last year

SOLUTION:

If the value of the house decreased by 20% during last year, this means the value of the house this year is 80% of last year's value.

Let the value of the house last year be 'x'.

If the value of the house today is  $184,000, then:

                           \(80/100 * x = 184,000\\\\0.8x = 184,000\\\\x = 184,000/0.8\\\\x = 230,000\)

Therefore, the last year value of the house will be $230,000.

The required probability of occupying seats at the end of the row by April and Bobby is equals to 0.0333.

We have,

Number of chairs in a row =  5

April and Bobby need to occupy the two end chairs.

The other two people, Bill and Candace, can sit in any of the 3 remaining chairs.

The total number of ways to seat the 4 people in the 5 chairs is

= 5!/(5-4)!

= 5x4x3x2

= 120.

April can sit in either of the two end chairs, and then Bobby can sit in the other end chair.

Bill and Candace can then sit in either of the two remaining chairs, in either order.

The number of ways to seat April and Bobby at the ends of the row is,

=  2x1x2x1

= 4.

Probability that April and Bobby will occupy the seats at the end of the row is,

4/120

= 1/30

Answer: A

Step-by-step explanation:

Median is better than mean as it is not affected by extremely high or low values in the same way that the mean is

The median is a measure of central tendency, like the mean, but it is not affected by extremely high or low values in the same way that the mean is. Because of this, the median is often a better measure of central tendency when there are outliers in the data, or when the data is skewed (not normally distributed). For example, consider the following set of numbers: 1, 2, 3, 100. The mean of these numbers is 26, but the median is 3, which is a better representation of the "typical" value in this set.

However, the mean is still a useful measure and has its own advantages. For example, the mean is sensitive to every value in the data set, so it can provide a more comprehensive summary of the data. Additionally, the mean is easier to work with mathematically than the median, so it is often used in statistical tests and calculations.

Using a two-day moving average approach, the forecast for the number of emergencies on Friday is 10.0 calls.

The two-day moving average approach is a simple forecasting method that calculates the average of the number of emergencies over the previous two days and uses it as the forecast for the next day. In this case, we have data for the number of emergencies for the last four evenings: Monday (10 calls), Tuesday (10 calls), Wednesday (10 calls), and Thursday (15 calls).

To calculate the forecast for Friday using the two-day moving average approach, we take the average of the number of emergencies on Thursday and Wednesday, which is (15 + 10) / 2 = 12.5 calls. However, since the question asks for the forecast rounded to 1 decimal place, the forecast for Friday would be 10.0 calls.

By applying the two-day moving average approach, the police station expects approximately 10.0 emergency calls on Friday based on the recent trend of emergencies over the past four evenings. It assumes that the pattern observed in the previous days will continue, with an equal weight given to each of the two days in the moving average calculation.
