The monthly payments after the down payment are $186.58 per month.

We will first calculate amount of the down payment which is:

= 10% * 6,250.

= $625.

So, the financed amount for the purchase will be:

= $6,250 - $625

= $5,625.

We will now calculate the amount of sales tax where tax rate is 8.25%, this give us:

= $6,250 * 8.25%

= $515.63.

The total amount financed including sales tax is:

= $5,625 + $515.63

= $6,140.63.

To calculate the monthly payments, we can use the formula M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

M = $6,140.63*  [ 0.005(1 + 0.005)^36 ] / [ (1 + 0.005)^36 – 1 ]

M = $6,140.63* 0.03042193745

The least amount of ratings the particular company can receive is 3 on the seventh survey and still be eligible to have an average of at least 8 for the first 10 surveys.

Here we have to implement basic algebraic application
Let us consider x as the  the least rating the company can get on the seventh survey.
The average of the first six surveys is 7.7, so their total score is 6 × 7.7 = 46.2.

The average of at least 8 for the first ten surveys, their total score should be at least 80.
So for the first ten surveys, their total score should be
80 = (46.2 + x + y)/10
Here
y = score for survey 8 and survey 9.

Evaluating for y
y = (80 - 46.2 - x × 2)/2
= (33.8 - x)/2.

As  each survey rating is an integer between 0 and 10 inclusive, we need to find the smallest integer value of x that makes y ≥ 0

Then, (33.8 - x)/2 >= 0.
Multiplying both sides by 2
33.8 - x >= 0
Subtracting 33.8 from both sides
-x >= -33.8
Multiplying both sides by -1
x <= 33.8
Hence, the smallest integer value of x that makes y ≥0 is x = 3.

Answer:

c = 6.

Step-by-step explanation:

x^2+cx+9 = (x + b)^2     where b is a constant

x^2 + cx + 9 = x^1 + 2bx + b^2

so 2b = c

and b^2 = 9

So b = 3

and c = 2*b = 6

To solve this problem, we will use the fact that the square of a binomial (a+b)^2 is equal to a^2 + 2ab + b^2.

Let's start by assuming that x^2 + cx + 9c is the square of a binomial (a+b)^2. Expanding (a+b)^2 using the formula above, we get:

(a+b)^2 = a^2 + 2ab + b^2

If we compare this to x^2 + cx + 9c, we see that:

a^2 = x^2      (1)
2ab = cx       (2)
b^2 = 9c        (3)

From (1), we get a = ±√x^2 = ±x.

Substituting a = ±x into (2), we get:

2(±x)b = cx

Simplifying this equation, we get:

b = ±(c/2)

Substituting a = ±x and b = ±(c/2) into (3), we get:

x^2 + (c/2)^2 = 9c

Multiplying both sides by 4, we get:

4x^2 + c^2 = 36c

Rearranging this equation, we get:

4x^2 - 36c + c^2 = 0

This is a quadratic equation in c. Using the quadratic formula, we get:

c = (36 ± √(36^2 - 4(4)(c^2))) / (2(4))

Simplifying this equation, we get:

c = (9 ± √(81 - c^2)) / 2

Since c is nonzero, we can ignore the solution c = 0. Therefore, we have:

c = (9 + √(81 - c^2)) / 2   or   c = (9 - √(81 - c^2)) / 2

We can check that both solutions satisfy the original condition that x^2 + cx + 9c is the square of a binomial.

However, we need to ensure that the square root in each solution is real, which means that 81 - c^2 ≥ 0.

For the first solution, we have:

81 - c^2 ≥ 0

c^2 ≤ 81

|c| ≤ 9

Therefore, the first solution is valid for c such that -9 ≤ c ≤ 9.

For the second solution, we have:

81 - c^2 ≥ 0

c^2 ≤ 81

|c| ≥ 9

However, we already know that c is nonzero, so |c| > 0. Therefore, the second solution is not valid for any value of c.

Therefore, the only valid solution is:

c = (9 + √(81 - c^2)) / 2,   for -9 ≤ c ≤ 9.

I hope this helps! Let me know if you have any questions.
If x^2 + cx + 9c is equal to the square of a binomial, then it can be written in the form (x + A)^2, where A is a constant. Expanding the square of the binomial, we get:

(x + A)^2 = x^2 + 2Ax + A^2

Comparing this with the given expression, x^2 + cx + 9c, we can deduce the following:

2A = c and A^2 = 9c

We are asked to find the value of c. Using the first equation (2A = c), we can substitute c in the second equation:

A^2 = 9(2A)
A^2 = 18A

Since A is nonzero, we can divide both sides by A:

A = 18

Now, using the first equation, we can find the value of c:

c = 2A
c = 2(18)
c = 36

Therefore, the value of c is 36.

The diameter of the circle is d = 124.73 cm

The diameter of a circle is the line that passes through the center of the circle and touches the circumference at two points.

To find the diameter of the circle, we use the formula for the area of the circle given by A = πd²/4 where d = diameter of circle

Making d subject of the formula, we have that

d = √(4A/π)

Given that the area is

substituting the values of the variables into the equation, we have that

d = √(4A/π)

d = √(4 × 98 cm²/22/7)

d = √(4 × 98 cm² × 7/22)

d = √(4 × 98 cm² × 7/22)

d = √(2744 cm²/22)

2. The standard deviation of the populace (which we'll expect is known).

3. The margin of error (which is the greatest separation between the test cruel and the genuine populace cruel that we're willing to endure).

Assuming we know the standard deviation of the populace, ready to utilize the equation:

n = (z²* σ²) / E²

where:

n is the test measure

z is the z-score compared to the level of certainty (which is 1.645 for 90% certainty)

σ is the standard deviation of the populace

E is the edge of mistake

We ought to select esteem for E, which speaks to the most extreme separation between the test cruel and the genuine populace cruel(mean) that we're willing to endure.

For case, in the event that we need the interim to have a width of no more than 0.1 units, at that point we would select E = 0.1/2 = 0.05.

So, stopping within the values we know, we get:

Step-by-step explanation:

To determine the cost of the car inclusive of VAT, trade-in, and other fees, we first need to calculate the VAT amount. Assuming the VAT rate is 15%:

VAT = 0.15 x $75,000 = $11,250

Next, we can calculate the total cost of the car, inclusive of VAT:

Total cost of car = Cost of car + VAT

Total cost of car = $75,000 + $11,250

Total cost of car = $86,250

We also need to take into account the trade-in and the other fees. The trade-in value of $9,500 and the other fees of $2,000 are subtracted from the total cost of the car:

Total cost of car inclusive of VAT and other fees = Total cost of car + Trade-in value - Other fees

Total cost of car inclusive of VAT and other fees = $86,250 + $9,500 - $2,000

Total cost of car inclusive of VAT and other fees = $93,750

Therefore, the cost of the car, inclusive of VAT, trade-in, and other fees, is $93,750.

To decrease the type II error in a hypothesis test while maintaining the type I error at its current level, we need to increase the sample size.

Type I error shows when we reject a null hypothesis which is actually true. Type II error shows when we fail to reject a null hypothesis which is actually false.

Increasing the sample size can decrease the probability of making a Type II error, as it increases the power of the hypothesis test. Probability of correctly rejecting a false null hypothesis is called power.

By increasing the sample size, we can increase the power of the test while maintaining the significance level (and thus the type I error) at its current level.

This means that we will be less likely to miss a true effect (i.e., lower the probability of making a Type II error) while still controlling the probability of false positives (i.e., Type I error) at the desired level.

Answer:

We can rewrite the given expressions as:

(3x² - y² - 2yz - z²) and (y² - z² - 2zx - x²)

To find the H.C.F., we can use the Euclidean algorithm. We start by dividing the first expression by the second expression:

(3x² - y² - 2yz - z²) ÷ (y² - z² - 2zx - x²)

Using long division or synthetic division, we get:

(3x² - y² - 2yz - z²) = (3x + y + z)(x - y + z) + 2y(x - z)

Therefore, the remainder is 2y(x - z). We can now divide the second expression by this remainder:

(y² - z² - 2zx - x²) ÷ 2y(x - z)

Using long division or synthetic division, we get:

(y² - z² - 2zx - x²) = -x(x - y + z) + z(x - y + z)

Therefore, the remainder is z(x - y + z).

Since the second remainder is not zero, we need to continue with the algorithm. Now we divide the remainder 2y(x - z) by the remainder z(x - y + z):

2y(x - z) ÷ z(x - y + z)

Using long division or synthetic division, we get:

2y(x - z) = 2y(x - y + z) - 2y²

Therefore, the remainder is -2y². Now we divide the previous remainder z(x - y + z) by this new remainder:

z(x - y + z) ÷ (-2y²)

Using long division or synthetic division, we get:

z(x - y + z) = -1(-2y²) + z²

Therefore, the H.C.F. of the original expressions is the absolute value of the last remainder, which is |-2y²| = 2y².

Therefore, the H.C.F. of (3x² - y² - 2yz - z²) and (y² - z² - 2zx - x²) is 2y².
