x = -19 -6y 2x + 3y = -11

x+6y = -19 2x + 3y = -11

2(x+6y)= 2(-19) 2x + 3y = -11

2x + 12y = -38 2x + 3y = -11

subtracting both equation

2x + 12y-(2x + 3y) = -38-(-11)

2x+12y-2x-3y = -38+11

9y= -27

y= -3

x= -19-(6×(-3))

x= -19+18

x= -1

x= -1 and y = -3

The number of late insurance claim payouts per 100 should be measured with a p-chart. Therefore, the correct option is (e) p-chart.

A p-chart is a type of control chart used to monitor the proportion of nonconforming items in a sample, where nonconforming items are those that do not meet a certain quality standard or specification. In this case, the proportion of late insurance claim payouts would be the proportion of nonconforming items.

A p-chart is appropriate when the sample size is constant and the number of nonconforming items per sample can be either small or large. It is used to monitor the stability of a process and to detect any changes or shifts in the proportion of nonconforming items over time.

An X-bar chart and R-chart are used to monitor the mean and variability of a continuous variable, respectively, and would not be appropriate for measuring the number of nonconforming items.

Amira's age is 12 years when Amira is younger than Marques and their ages are consecutive integers and the sum of Amira's age and 2 times Marques's age is 38.

According to the question,

We have the following information:

Amira is younger than Marques.

Their ages are consecutive integers.

The sum of Amira's age and 2 times Marques's age is 38.

Now, let's take Amira's age to be x years.

Then, Marques's age will be (x+1) years.

So, we have:

x + 2(x+1) = 38

x + 2x + 2 = 38

3x+2 = 38

3x = 38-2 (Moving 2 from the left hand side to the right hand side will result in the change of the sign from plus to minus.)

3x = 36

x = 36/3

x = 12 years

Hence, Amira's age is 12 years.

The distance from the sun to the other focus is 5.01 × 10⁹ m.

(a) The distance from the center of an ellipse to a focus is an where a is the semi major axis and e is the eccentricity. Thus, the separation of the foci ( in the case of Earth's orbit ) is;

2ae = 2(1.50 × 10¹¹)(0.0167) = 5.01 × 10⁹ m.

(b) To express this in terms of solar radii, we set up a ratio;

a. The common difference (d) of the arithmetic sequence is 2, and the first term (a₁) is 8.

b. he next three terms are: a₄ = 14, a₅ = 16, a₆ = 18

(a) In an arithmetic sequence, the common difference (d) is the constant value added to each term to obtain the next term. In this sequence, the common difference can be identified by subtracting consecutive terms:

10 - 8 = 2

12 - 10 = 2

So, the common difference (d) is 2.

The first term (a₁) of the sequence is the initial term. In this case, a₁ is the first term, which is 8.

Therefore:

d = 2

a₁ = 8

(b) To find the next three terms, we can simply add the common difference (d) to the previous term:

Next term (a₄) = 12 + 2 = 14

Next term (a₅) = 14 + 2 = 16

Next term (a₆) = 16 + 2 = 18

So, the next three terms are:

a₄ = 14

a₅ = 16

a₆ = 18

(a) Since the first term is 8, we can identify a₁ (the first term) as 8.

So, d = 2 and a₁ = 8.

(b) the sixth term (a₆) is 18.

(a) In an arithmetic sequence, the common difference (d) is the constant value added to each term to obtain the next term.

In the given sequence, we can observe that each term is obtained by adding 2 to the previous term. Therefore, the common difference (d) is 2.

We can recognize a₁ (the first term) as 8 because the first term is 8.

So, d = 2 and a₁ = 8.

(b) To write the next three terms of the arithmetic sequence, we can simply add the common difference (d) to the previous term.

a₂ (second term) = a₁ + d = 8 + 2 = 10

a₃ (third term) = a₂ + d = 10 + 2 = 12

a₄ (fourth term) = a₃ + d = 12 + 2 = 14

Therefore, the next three terms are 10, 12, and 14.

To find a₆ (sixth term), we can continue the pattern

a₅ = a₄ + d = 14 + 2 = 16

a₆ = a₅ + d = 16 + 2 = 18

So, the sixth term (a₆) is 18.

The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.

The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.

Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.

Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

The total amount of money earned on Thursday was $1090.

The table showing the number of house calls by each plumber is attached below. The total amount of money earned by all three plumbers on Monday was $1,400. On Tuesday, they earned a total of $1,660, and on Wednesday, they earned a total of $1,650. On Thursday, plumber A made four house calls, plumber B made six house calls, and plumber C made three house calls. We need to calculate the total amount of money earned on Thursday.

Let the money earned per call by plumbers A, B, and C be x, y, and z. We can form three equations, as given below.

2x + 8y + 8z = 1400

4x + 7y + 10z = 1660

3x + 9y + 9z = 1650

Upon solving the above three linear equations, the values of x, y, and z are 100, 80, and 70, respectively.

The total amount of money earned on Thursday is calculated below.

A = 4x + 6y + 3y

A = 4*100 + 6*80 + 3*70

A = 400 + 480 + 210

A = 1090

Hence, the total amount of money earned on Thursday is $1090.

When given a function f defined as f(x) = ax + b, where a and b are constants, and f(3) = 10 and f(8) = 12, the values of a and b are 0.4 and 0.8, solved using a system of equations. So the right answer is O a = 0.4, b = 8.8.

The values of a and b can be determined as follows:

f(3) = 10 implies that 10 = 3a + bf(8) = 12 implies that 12 = 8a + b

We can solve this system of equations to get the values of a and b.

One way to do this is to use elimination: We can eliminate b by subtracting the first equation from the second equation: 12 - 10 = (8a + b) - (3a + b)2 = 5a

Solving for a, we get a = 2/5.

Substituting this value of a into the first equation, we can solve for b:10 = 3a + bb = 10 - 3a

Substituting the value of a = 2/5, we get: b = 10 - 3(2/5)b = 10 - 6/5b = 44/5

Therefore, the values of a and b are: a = 2/5 and b = 44/5.

The correct answer is: a = 0.4, b = 8.8.

In this case, Asset A has a return of 16% and represents 60% of the portfolio, while Asset B has a return of 22% and represents 40% of the portfolio. The correlation between Asset A and B is given as 0.93.

To calculate the expected return of the portfolio, we use the following formula:

Expected Return = (Weight of Asset A * Return of Asset A) + (Weight of Asset B * Return of Asset B) + (2 * Weight of Asset A * Weight of Asset B * Correlation between A and B * Standard Deviation of Asset A * Standard Deviation of Asset B)The expected return for a portfolio composed of two assets, A and B, can be calculated using the weighted average of the individual asset returns, considering their respective weights in the portfolio.

By plug in the given values and performing the calculations, we can determine the expected return for the portfolio comprised of 60% Asset A and 40% Asset B.
