5. Find the slope-intercept form of the line with slope m= 6 and which passes through the point (11, - 10).

The value of Cpk is 1.

The value of Cpk can be calculated using the formula: Cpk = min((USL - X-bar-bar) / (3 * o'), (X-bar-bar - LSL) / (3 * o')).

In this case, the given values are:

USL = 1.012

LSL = 0.988

Nominal = 1.000

X-bar-bar = 1.003

o' = 0.003

To calculate Cpk, we substitute these values into the formula.

Using the formula: Cpk = min((1.012 - 1.003) / (3 * 0.003), (1.003 - 0.988) / (3 * 0.003)) = min(0.009 / 0.009, 0.015 / 0.009) = min(1, 1.67) = 1.

Therefore, the value of Cpk is 1.

Cpk is a process capability index that measures how well a process is performing within the specified tolerance limits. It provides an assessment of the process's ability to consistently produce output that meets the customer's requirements.

In the given problem, the process characteristics are defined by the upper specification limit (USL), lower specification limit (LSL), nominal value, the average of the subgroup means (X-bar-bar), and the within-subgroup standard deviation (o').

To calculate Cpk, we compare the distance between the process average (X-bar-bar) and the specification limits (USL and LSL) with the process variability (3 times the within-subgroup standard deviation, denoted as 3 * o'). The Cpk value is determined by the smaller of the two ratios: (USL - X-bar-bar) / (3 * o') and (X-bar-bar - LSL) / (3 * o'). This represents how well the process is centered and how much variability it exhibits relative to the specification limits.

In this case, when we substitute the given values into the formula, we find that the minimum of the two ratios is 1. Therefore, the process is capable of meeting the specifications with a Cpk value of 1. A Cpk value of 1 indicates that the process is capable of producing within the specified limits and is centered between the upper and lower specification limits.

The resulting fraction is 35/12..Converting the fraction back to a mixed number, we find that 35/12 is equal to 2 and 11/12.Comparing this result to 2 and k/12, we can see that k = 11.5 and 2/3 minus 2 and 3/4 equals 2 and 11/12, where k = 11.

To prove that 5 and 2/3 minus 2 and 3/4 is equal to 2 and k/12, we'll perform the necessary operations to determine the value of k.

First, let's convert the mixed numbers into improper fractions:5 and 2/3 can be written as (3*5 + 2)/3 = 17/3.

2 and 3/4 can be written as (4*2 + 3)/4 = 11/4.

Now, subtracting these fractions: (17/3) - (11/4).

To find the common denominator, we multiply the denominators: 3 * 4 = 12.Rewriting the fractions with the common denominator, we have: (68/12) - (33/12).Subtracting the numerators, we get: 68 - 33 = 35.

The original price of a swimsuit is 47.90.

What is an expression?

Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that;

The price of a swimsuit after discount of 5% = 45.50

Now, Let the original price of swimsuit = x

Then we can formulate;

x - 5% of x = 45.50

( x - 5x/100 ) = 45.50

(100x - 5x)/100 = 45.50

95x / 100 = 45.50

95x = 45.50 × 100

95x = 4550

x = 4550 ÷ 95

x = 47.895

After round to the nearest cent,

x = 47.90

Thus, The original price of a swimsuit is 47.90.

To determine whether a vector b is in the column space of a matrix A, we need to check if there exists a solution to the system Ax=b.  we can express w as a linear combination of the row vectors of A. Hence, w is in row(A) and b is not in col(A).

If a solution exists, then b is in col(A). If a solution does not exist, then b is not in col(A). Let's apply this to the given problem. We have A = [1 0 -1] and b = [3].

To check if b is in col(A), we need to solve the system Ax=b. This gives us the equation: (1)x + (0)y + (-1)z = 3 where x, y, and z are the unknowns. Rearranging this equation, we get: x - z = 3 This is a linear equation in two variables, x and z.

It represents a line in the x-z plane. We can see that this line does not pass through the origin, which means that there is no solution to this equation in the form of Ax=b.

Therefore, b is not in col(A). To determine whether a vector w is in the row space of a matrix A, we need to check if w can be expressed as a linear combination of the row vectors of A. If w can be expressed in this form, then w is in row(A).

Therefore, we can express w as a linear combination of the row vectors of A. Hence, w is in row(A).

Answer:

x = 46°

Step-by-step explanation:

Angles on a straight line sum to 180°.

Therefore, the interior angle of the triangle that forms a linear pair with the exterior angle marked 130° is:

⇒ 180° - 130° = 50°

The interior angle of the triangle that forms a linear pair with the exterior angle marked 96° is:

⇒ 180° - 96° = 84°

The interior angles of a triangle sum to 180°. Therefore:

⇒ 50° + 84° + x = 180°

⇒ 134° + x = 180°

⇒ 134° + x - 134° = 180° - 134°

⇒ x = 46°

Therefore, the size of angle x is 46°.

The component form of the vector with magnitude 5 and direction angle 60° is u = [2.5, 4.33].

To find the component form of a vector with magnitude and direction angle, we can use the following formula:

u = [magnitude * cos(direction angle), magnitude * sin(direction angle)]

where

u is the vector,

magnitude is the magnitude of the vector, and

direction angle is the angle between the vector and the positive x-axis, measured in a counterclockwise direction.

Let's consider an example to illustrate this formula: Find the component form of a vector with magnitude 5 and direction angle 60°. We can use the formula,

u = [magnitude * cos(direction angle), magnitude * sin(direction angle)]

Substituting the given values, we get,

u = [5 * cos(60°), 5 * sin(60°)]

Evaluating the trigonometric functions, we get,

u = [2.5, 4.33]

Therefore, the component form of the vector with magnitude 5 and direction angle 60° is u = [2.5, 4.33].

The best reason to prefer the least-squares regression line that uses x to predict log(y) would be that the standard deviation of the residuals is smaller.

When we have a scatterplot that shows a positive, nonlinear association, we may attempt to transform the data to linearize the association.

In this case, two different transformations were attempted, using the logarithm of the y values and using the square root of the y values.

Two least-squares regression lines were then calculated, one that uses x to predict log(y) and the other that uses x to predict Vy.
To determine which of these regression lines is preferred, we need to consider several factors.

One important factor is the value of r2, which tells us how much of the variability in the response variable (y) is explained by the regression model.

A larger r2 indicates a better fit to the data.
However, in this case, the value of r2 alone may not be sufficient to determine which regression line is preferred.

Another important factor to consider is the standard deviation of the residuals, which measures how much the actual values of y deviate from the predicted values. A smaller standard deviation of the residuals indicates a better fit to the data.

Furthermore, we should also consider the slope of the regression line, which tells us the direction and strength of the relationship between x and y.

A greater slope indicates a stronger relationship.
In addition, we need to examine the residual plot, which shows the difference between the actual values of y and the predicted values.

A residual plot with more random scatter indicates a better fit to the data.

Finally, we should also consider the distribution of residuals, which should be approximately Normal. A more Normal distribution of residuals indicates a better fit to the data.

Step-by-step explanation:

The mass of the fifth man is 153 kg.

The mean mass of five men is 76 kg.

The masses of four of the men are 72 kg, 74 kg, and 81 kg.

To solve this problem, we need to apply the concept of the mean of a set of data.

The mean is the average of all the values in a set of data.

It is calculated by adding up all the values and dividing by the total number of values in the set.

To find the mass of the fifth man, we need to use the mean of the entire set and the masses of the four men that are already given.

The formula to find the mean of a set of data is:

\(Mean = \frac{(sum of all the values)}{(total number of values)}\)

Let x be the mass of the fifth man.

Then we can write an equation using the given information:

\(Mean = \frac{(72 + 74 + 81 + x)}{5}\)

Substitute the given mean of 76 kg into the equation and solve for x:

\(76 = \frac{(72 + 74 + 81 + x)}{576 × 5} = 227 + x\)

Multiply both sides by 5:

\(380 = 227 + x\)

Subtract 227 from both sides:

\(153 = x\)

Therefore, the mass of the fifth man is 153 kg.

Answer:

p=(-0.0125n) + 42.5

Step-by-step explanation:

Let p= price

n = number of shirts

m = slope of the line (note, the more shirts, the lower the price, so we know it's going to be negative)

b = y intercept

There are two points which are (1000, $30) and (3000, $5)

Our slope m = (p1-p2)/(n1-n2)

Filling in from our points m = (30-5)/(1000-3000)

m = 25/-2000

m = -0.0125

Since we have determined our slope, we can now find our equation

p-p1=m(n-n1)

p-30=(-0.0125)(n-1000)

p-30= (-0.0125n) + 12.5

p=(-0.0125n) + 42.5

Then, we can double check with the other point there:

p=(-0.0125n) + 42.5

5? (-0.0125x 3000) + 42.5

5= 5

Therefore,linear equation in the form p(n) is

Step-by-step explanation:

The probability of flipping a heads on the coin and rolling a 5 on the die is 1/12 if a coin is flipped and die is rolled once.

The sample space for the coin toss is  {H,T}, so there are two possible outcomes. The favorable one is  H.

The probability of flipping a heads on the coin is equal to 1/2.

Die has six faces, meaning six possible outcomes, but we’re only interested in one of those outcomes: that roll of a 5. That means that only 1 in 6 outcomes is desirable and we can write it as  1/6

The probability of rolling a 5 on the die is equal to 1/6.

Since a coin is flipped and die is rolled independently, the joint probability is a product of above probabilities.

Therefore, the probability of flipping a heads on the coin and rolling a 5 on the die equals

\(\frac{1}{2} \times \frac{1}{6}\\= \frac{1}{12}\)

The degrees of freedom for a chi-square goodness-of-fit test are determined by the number of categories or groups being compared minus 1.

In this case, k = 4 represents the number of categories, so the degrees of freedom would be (k - 1) = (4 - 1) = 3. However, the sample size n = 40 does not directly affect the degrees of freedom in this particular test.

The sample size is relevant in determining the expected frequencies for each category, but it does not impact the calculation of degrees of freedom. Therefore, the correct statement is that if a researcher computes a chi-square goodness-of-fit test with k = 4, the degrees of freedom for this test would be 3.

Given:

An athlete who makes \(4\dfrac{3}{4}\) laps in 3 mins 45 seconds on a 400m field.

To find:

The speed of the athlete in m/s.

Solution:

We know that,

Distance covered in 1 lap = 400 m

Distance covered in \(4\dfrac{3}{4}\) laps = \(4\dfrac{3}{4}\times 400\) m

                                               = \(\dfrac{19}{4}\times 400\) m

                                               = \(1900\) m

We know that,

1 minute = 60 seconds

3 minutes = 180 seconds

3 minutes 45 second = 180 + 45 seconds

                                   = 225 second

The speed of the athlete is:

\(Speed=\dfrac{Distance}{Time}\)

\(Speed=\dfrac{1900}{225}\)

\(Speed\approx 8.44\)

Therefore, the speed of the athlete is about 8.44 m/s.
