When two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.

A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.

A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

Therefore, when two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

Step-by-step explanation:

You want an amortization schedule for a loan of $55,000, repaid in 36 years with 3.9% interest compounded quarterly.

We assume the payments will be made quarterly. The amount of the payment is computed using the amortization formula:

  A = P(r/n)/(1 -(1 +r/n)^(-nt))

where P is the principal amount of the loan, r is the annual interest rate, n is the number of payments and compoundings per year, and t is the number of years.

For this loan, the payment amount is ...

  A = $55,000·(0.039/4)/(1 -(1 +0.039/4)^(-4·36)) = $712.42

The amount of interest is the quarterly interest rate multiplied by the balance. The interest due on the first payment is ...

  (0.039/4)·($55,000) = $536.25

The amount of the payment left after paying interest is applied to the principal amount. The balance of the loan is reduced by that amount.

For the first payment, the amount used to reduce the principal is ...

  $712.42 -536.25 = $176.17

As we said, the principal amount reduces the outstanding balance, so the balance after the first payment is ...

  $55,000 - 176.17 = $54,823.83

These calculations are repeated for each row of the table, so it is convenient to let a spreadsheet do them.

The graph of 3x-2y≤6 is the third graph, for 3x-2y<6 is the first graph, for 3x-2y>6 is the fourth graph and for 3x-2y≥6 is the second graph. The solution has been obtained using concept of linear inequality.

What is linear inequality?

A linear inequality is one that would produce a linear equation if the equals relation were used instead of the inequality. When multiplying or dividing both sides by a negative number in order to solve the inequality, the direction of the inequality is reversed. The entire set of solutions to an inequality is known as the solution set.

We are given for graphs, of which two graphs are dotted and two are simple straight line graphs.

The dotted graphs are drawn for the inequalities having < or >

Whereas the simple straight line graphs are drawn for the inequalities having ≤ or ≥.

Now, to notice the shaded pattern, we will see whether the equations are true for (0,0) or not

1. 3x-2y≤6

⇒ 0≤6

So, the equation is true for the point.

Hence, the third graph represents this equation.

2. 3x-2y<6

⇒ 0<6

So, the equation is true for the point.

Hence, the first graph represents this equation.

3. 3x-2y>6

⇒ 0>6

So, the equation is false for the point.

Hence, the fourth graph represents this equation.

4. 3x-2y≥6

⇒ 0≥6

So, the equation is false for the point.

Hence, the second graph represents this equation.

Hence, the graphs are matched with the inequalities.

The value of the expression tan(-5π/6) can be determined using trigonometric properties and  identities.

First, let's consider the unit circle. The angle -5π/6 is measured in the clockwise direction from the positive x-axis. In this position, the reference angle is π/6, which is the positive angle formed with the x-axis.

The tangent function (tan) is defined as the ratio of the sine (sin) of an angle to the cosine (cos) of the angle. Using the reference angle π/6, we can determine the value of tan(π/6) as the ratio of sin(π/6) to cos(π/6). sin(π/6) equals 1/2, and cos(π/6) equals √3/2. Therefore, tan(π/6) is (1/2) divided by (√3/2), which simplifies to 1/√3 or √3/3. Since tan is an odd function, tan(-5π/6) is equal to the negative of tan(5π/6). Therefore, tan(-5π/6) has the same value as -√3/3.

In conclusion, the value of tan(-5π/6) is -√3/3, which means that the tangent of the angle -5π/6 is negative and equal to the ratio of -√3 to 3.

We can conclude that exactly half of these nonzero elements (i.e., 10 out of 20) are squares in GF(21).

To show that exactly half the nonzero elements in the finite field GF(p) are squares, where p is a prime number, we can use the fact that the nonzero elements in GF(p) form a cyclic group of order p-1 under multiplication.

Let's consider GF(2) as an example, where p = 2. In this case, the nonzero elements are {1}, and 1 is the only square element since 1² = 1. Thus, half of the nonzero elements (i.e., 1 out of 2) are squares.

Now let's consider a prime number p > 2. The nonzero elements in GF(p) are {1, 2, 3, ..., p-1}. We know that the order of the multiplicative group of GF(p) is p-1, and this group is cyclic. Therefore, we can write the elements as powers of a generator α: {α⁰, α¹, α², ..., \(\alpha ^{p-2}\)}.

To determine whether an element x is a square, we need to find another element y such that y² = x. Let's consider the element \(\alpha ^{k}\), where 0 ≤ k ≤ p-2. We can write \(\alpha ^{k}\) = \(\alpha ^{i^{2} }\), where 0 ≤ i ≤ (p-2)/2.

Now, if \(\alpha ^{k}\) is a square, then there exists an i such that \(\alpha ^{k}\)= \(\alpha ^{i^{2} }\). Taking the square root of both sides, we get \(\alpha ^{k}\) = \(\alpha ^{2i}\). This implies that k ≡ 2i (mod p-1), which means k and 2i are congruent modulo p-1.

Since 0 ≤ k ≤ p-2 and 0 ≤ i ≤ (p-2)/2, there are exactly (p-1)/2 possible values for k. For each of these values, we can find a corresponding i such that \(\alpha ^{k}\) = \(\alpha ^{i^{2} }\). Thus, exactly half of the nonzero elements in GF(p) are squares.

In the case of p = 21, we have a prime number. The nonzero elements in GF(21) are {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}. Following the same reasoning, we can conclude that exactly half of these nonzero elements (i.e., 10 out of 20) are squares in GF(21).

To find the probability of either event occurring, we can use the formula for the union of two events: P(A or B) = P(A) + P(B) - P(A and B).

Given that P(A) = 0.6, P(B) = 0.5, and P(A and B) = 0.25, we can substitute these values into the formula.

\(P(A or B) = P(A) + P(B) - P(A and B)\)
\(P(A or B) = 0.6 + 0.5 - 0.25\)
\(P(A or B) = 0.85 - 0.25\)
\(P(A or B) = 0.60\)

The probability of either event occurring can be found by adding the probabilities of the individual events and subtracting the probability of both events happening together. In this case, the probability of either event A or event B occurring is 0.6.

The probability of either event occurring can be calculated using the principle of addition. To find the probability of either event happening, we need to sum the individual probabilities of the events and subtract the probability of both events happening together.

Given:

p(a) = 0.6 (probability of event A occurring)
p(b) = 0.5 (probability of event B occurring)
p(a and b) = 0.25 (probability of both events happening together)

To calculate the probability of either event occurring, we can use the formula:

p(a or b) = p(a) + p(b) - p(a and b)

Substituting the given values into the formula:

p(a or b) = 0.6 + 0.5 - 0.25

p(a or b) = 0.85 - 0.25

p(a or b) = 0.6

Therefore, the probability of either event A or event B occurring is 0.6.

To understand this concept better, let's consider an example. Suppose event A represents rolling a fair six-sided die and getting an even number (2, 4, or 6). The probability of event A occurring would be 0.5. Now, let event B represent flipping a fair coin and getting heads. The probability of event B occurring would be 0.5.

If we want to find the probability of either rolling an even number or flipping heads, we can use the formula mentioned earlier. The probability of rolling an even number is 0.5, the probability of flipping heads is 0.5, and the probability of both happening together is 0.25. Plugging these values into the formula, we get:

p(A or B) = 0.5 + 0.5 - 0.25

              = 0.75

Therefore, the probability of either rolling an even number or flipping heads is 0.75.

The possible number of students in Mrs. Hayko's class is limited to 15 or 30, as higher multiples of 15 would exceed the desired class size.

Step-by-step explanation:

a)

Let 'x' be the total number of students in Mrs. Hayko's class.

One-third of the students walk to school: (1/3)x.

The remaining students who do not walk to school: (2/3)x.

Four-fifths of the non-walking students take the bus: (4/5) * (2/3)x.

Simplify to find the fraction of students taking the bus: (8/15)x.

b)

Consider different values for 'x' to find a whole number of students taking the bus.

Start with a small number, such as x = 15.

Calculate the number of students taking the bus using (8/15)x.

If the result is a whole number, it's a possible class size.

Repeat with different values of 'x' until a whole number is obtained.

The possible number of students in Mrs. Hayko's class could be 15, 30, or any other multiple of 15.

Step-by-step explanation:

The total sales for the week are $1000.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Commission percentage = 20%

Total sales = T

Now,

Commission earned = $200

This means,

20% of T = 200

(20/100) x T = 200

T = (200 x 100)/20

T = 1000
