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.

Answer:

$1400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

P = 378 / ( 0.09 × 3 ) = 1400

P = $ 1,400.00

The principal required to

accumulate interest of $ 378.00

on a rate of 9% per year for 3 years is $ 1,400.00.

The distribution of Y, representing the number of marbles drawn until a red marble is obtained, follows a geometric distribution with parameter p, which is the probability of drawing a red marble on any given trial.

In this scenario, we have a series of independent trials, each with two possible outcomes: drawing a red marble (success) or drawing a non-red marble (failure). Since we keep drawing marbles with replacement, the probability of drawing a red marble remains constant for each trial.

Let p be the probability of drawing a red marble on any given trial. The probability of drawing a non-red marble (failure) on each trial is (1 - p). The probability of drawing the first red marble on the Yth trial is given by the geometric distribution formula:

P(Y = y) = (1 - p)^(y-1) * p

Where y represents the number of trials until the first success (i.e., drawing a red marble). The exponent (y-1) accounts for the number of failures before the first success.

The geometric distribution formula allows us to calculate the probability of obtaining the first success on the Yth trial.

The length of the other base is 4 meters.

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as 1/2 x the sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

We have,

The area of a trapezoid.

A = (1/2) h (b1 + b2)

where A is the area, h is the height, b1, and b2 are the lengths of the two bases.

The point of diminishing returns is (20.98, 21247.3).

The point of diminishing returns occurs when the marginal cost of producing an extra unit of output exceeds the marginal revenue generated from selling that unit. Mathematically, it is the point at which the derivative of the production function equals zero and the second derivative is negative.

Given the polynomial function N(x) of degree 3, we can find the point of diminishing returns by finding the critical points where the first derivative equals zero and evaluating the second derivative at those points.

The derivative of N(x) is N'(x) = -18x² + 360x + 2250. To find the critical points, we set N'(x) = 0:

0 = -18x² + 360x + 2250

Dividing by -18 simplifies the equation:

0 = x² - 20x - 125

Using the quadratic formula, we find the solutions to the equation:

x₁,₂ = (20 ± √(20² - 4(1)(-125))) / 2(1)

x₁,₂ = 10 ± 5√5

Thus, the two critical points of N(x) are at x = 10 - 5√5 and x = 10 + 5√5.

To determine the point of diminishing returns, we evaluate the second derivative N''(x) = -36x + 360 at these critical points:

N''(10 - 5√5) = -36(10 - 5√5) + 360 ≈ -264.8

N''(10 + 5√5) = -36(10 + 5√5) + 360 ≈ 144.8

From the evaluations, we find that N''(10 + 5√5) is negative while N''(10 - 5√5) is positive. Therefore, the point of diminishing returns corresponds to x = 10 + 5√5.

To find the corresponding y-coordinate (N(10 + 5√5)), we can substitute the value of x into the original function N(x).

Hence, the point of diminishing returns is approximately (20.98, 21247.3).

Answer:

(x + 6)(x + 7)

Step-by-step explanation:

To factor the trinomial x^2 + 13x + 42, we need to find two numbers that multiply to 42 and add up to 13.

One way to do this is to list all the pairs of factors of 42 and see which pair adds up to 13:

1, 42 -> 1 + 42 = 43

2, 21 -> 2 + 21 = 23

3, 14 -> 3 + 14 = 17

6, 7 -> 6 + 7 = 13

So the pair of factors that we want is 6 and 7. We can use these numbers to rewrite the middle term of the trinomial:

x^2 + 13x + 42 = x^2 + 6x + 7x + 42

Next, we can group the first two terms and the last two terms:

x^2 + 6x + 7x + 42 = (x^2 + 6x) + (7x + 42)

Now, we can factor out the greatest common factor from each group:

x(x + 6) + 7(x + 6)

Notice that we have a common factor of (x + 6) in both terms. We can factor this out:

(x + 6)(x + 7)

from 12 to 24 we multiply by 2 again

and then we got \(\boxed{48}\) , 96 , 192, 384, etc ...

For the second example

let s estimate the constant

\(\dfrac{\dfrac{56}{27}}{\dfrac{28}{9}}=\dfrac{56*3}{27*28}=\dfrac{2}{3}\)

the second term is then

\(7*\drac{2}{3} = \boxed{ \ \dfrac{14}{3}\ }\)

Answer:

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

Step-by-step explanation:

Hamish and Harry work as plumbers. Harry earns a dollar more than 5/4 the amount Hamish earns per hour. The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour. How much does each of them earn per hour?

Hamish earnings per hour = x

Harry earnings = 1 + 5/4x

The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour

Harry also earns = 7/5x - 2

Equate both Harry's earnings

1 + 5/4x = 7/5x - 2

Collect like terms

1 + 2 = 7/5x - 5/4x

3 = 28x-25x/20

3 = 3/20x

Divide both sides by 3/20

x = 3 ÷ 3/20

= 3 × 20/3

x = 20

Hamish earnings per hour = x

= $20

Substitute Harry's earnings into 7/5x - 2

= 7/5 × 20 - 2

= 28 - 2

= 26

Harry's earnings = $26

D. Hamish earns $20 per hour, and Harry earns $26 per hour.

The value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

Given that a researcher measures the relationship between two variables, X and Y.

If SS(XY) = 340 and SS(X)SS(Y) = 320,000, then we need to calculate the value of the correlation coefficient.

Correlation coefficient:

The correlation coefficient is a statistical measure that determines the degree of association between two variables.

It is denoted by the symbol ‘r’.

The value of the correlation coefficient lies between -1 and +1, where -1 indicates a negative correlation, +1 indicates a positive correlation, and 0 indicates no correlation.

How to calculate correlation coefficient?

The formula to calculate the correlation coefficient is as follows:

r = SS(XY)/√[SS(X)SS(Y)]

Now, substitute the given values, we get:

r = 340/√[320000]r = 0.34

Therefore, the value of the correlation coefficient is 0.34. Thus, the option (B) 0.34 is the correct answer.

The length of a side of the regular hexagon is \(6units\).

For \(w\):

Since the perpendicular line, \(x\), passes through the center of the hexagon, it bisects the side on which \(w\) lies. Therefore,

\(w=\dfrac{1}{2}\times \text{side}\\=\dfrac{1}{2}\times 6units=3units\)

For \(x\), \(y\), and \(z\):

The line \(x\) is perpendicular to the side of the hexagon and bisects a side of the hexagon.

The line \(y\) passes through the center of the hexagon, hence it bisects the interior angle of the hexagon. Also,

\(y=6units\)

since it is half the diagonal of the hexagon. The diagonal is twice the side-length.

To calculate the size of an interior angle of a hexagon, we use the formula

\(2z=\dfrac{180^\circ(n-2)}{n}\)

Each interior angle is twice \(z\). Since \(n=6\)

\(2z=\dfrac{180^\circ(6-2)}{6}\\\\2z=\dfrac{180^\circ\times4}{6}\\\\z=60^\circ\)

The lines \(x\), \(y\), and \(w\) form a right-angled triangle. Using Pythagoras theorem,

\(w^2+x^2=y^2\\3^2+x^2=6^2\\x^2=36-9=27\\x=3\sqrt3units\)

For \(a\):

\(a\) is an interior angle of the hexagon. Previously, we found that the interior angle

\(2z=a=120^\circ\)

For \(c\):

We have the relationship for the sum of the interior angles for the irregular triangle

\(50^\circ+120^\circ+c=180^\circ\)

the angle \(120^\circ\) is vertically opposite \(a\)

\(c=180^\circ-120^\circ-50^\circ=10^\circ\)

For \(b\):

Using the sine rule on the irregular triangle,

\(\dfrac{b}{sin50^\circ}=\dfrac{10}{sin120^\circ}\\\\b=\dfrac{10}{sin120^\circ}\times sin50^\circ\approx 8.8units\)

For \(d\):

\(\dfrac{b}{sin50^\circ}=\dfrac{d}{sin(c)}\\\\d=\dfrac{b}{sin50^\circ}\times sin(c)\\\\=\dfrac{8.8}{sin50^\circ}\times sin10^\circ\\\\\approx2.0units\)

The perimeter of the hexagon is

\(6\times \text{side}=6\times6=36units\)

The area of the hexagon is

\(6\times\dfrac{1}{2}\times \text{base}\times\text{height}\\\\3\times6\times x=3\times6\times 3\sqrt3\\=54\sqrt3\text{ sq.units}\)

perimeter of the triangle is

\(10+b+c=10+8.8+2.0\\=20.8units\)

area of the triangle is

The Measure of angle A is 120°, Measure of angle C = 120° and the Measure of angle D is 60°

In a parallelogram, opposite angles are congruent. Therefore, if the measure of angle A is 120°, then the measure of angle C is also 120°.

Since angle A and angle C are opposite angles, their adjacent angles are also congruent. This means that the measure of angle B is equal to the measure of angle Z.

Now, let's consider angle D. In a parallelogram, the sum of the measures of adjacent angles is always 180°. Since angle C is 120°, the adjacent angle D must be:

To write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10.

To write 10 more than a number, we need to use the mathematical operation of addition. Addition is the process of combining two or more numbers to find the total or sum.

In this case, we are given the number 5 and we are asked to find the number that is 3 more than it. To do this, we can use the mathematical notation: 10 + Number = N+10.

This notation means that we are adding 10 to a number, which results in N+10. The "+" symbol is the addition operator and it is used to indicate that we are performing an addition operation. The "=" symbol is used to indicate that the result of the addition is N+10.

Another way to write 10 more than a number is to use the phrase "10 plus a number". This phrase indicates that we are adding 10 to a number to get N+10.

Therefore, In short, to write 10 more than a number, we use the mathematical operation of addition and the notation 10 + Number = N+10. This means that we are adding 10 to a number, resulting in N+10. It can also be written as "10 plus N", indicating the same operation.
