Step-by-step explanation:

Hello!

The objective is to study both processes to see if there is any difference between the costs of manufacturing.

An ANOVA was conducted for the variable:

Y: cost of manufacturing automobile transmissions

Factor: Process

Treatments: 1 and 2

The statistic for this test is

\(F= \frac{MS_{Treatment}}{MS_{Error}} ~~F_{k-1; n-k}\)

Where

k= number of treatments

n= total number of observations

Degrees of freedom of the treatments: k-1= 2-1= 1

Degrees of freedom of errors: n-k= 20-2= 18

The critical region for this analysis is always one tailed to the right.

\(F_{k-1;n-k;1-\alpha }= F_{1;18;0.90}= 8.28\)

I hope this helps!

Using the F distribution and the appropriate degree of freedom values, the critical value of F at 0.1 is 8.29

From the table attached :

The Fcritical value can be defined thus :

\( F_{df \: treatment, \: df \: error, 1 - α} \)

Using the F distribution or calculator :

Hence, the critical value of F at 0.1 is 8.29

We need to use an arithmetic sequence to write a function.

So, the required arithmetic sequence for four weeks is

18, 22, 26, 30

Here, first term is 18 and common difference is 4. The range is  [18,30].

The explicit formula of n arithmetic sequence is

where, a is first term and d is common difference.

Substitute a=18 and d=4 in the above formula.

The function notation is

The function is f(x)=4x+14 and the range is  18 ≤ y ≤ 30.

Therefore, the correct option is C.

With 99% confidence that the true difference lies between 0.1316 and 0.2694.

A 99% confidence interval for the difference in average SAT scores between coached and uncoached students can be constructed using the data above.

The confidence interval is calculated as (mean of coached students - mean of uncoached students) +/- (2 * standard error of the difference in means).

The mean of coached students is (0.3098 + 0.3399 + 0.219 + 0.0798) / 4 = 0.2155, and the mean of uncoached students is (0.0046 + 0.0248) / 2 = 0.0147. The standard error of the difference in means can be calculated as the square root of ((0.2155(1-0.2155)/4) + (0.0147(1-0.0147)/2)).

The confidence interval is then (0.2155 - 0.0147) +/- (2 * 0.0347) = 0.201 +/- 0.0694, or (0.1316, 0.2694). This indicates that, on average, coached students gain 0.201 points more than uncoached students, with 99% confidence that the true difference lies between 0.1316 and 0.2694.

To calculate the mean, median, and mode, we first need to know what each of these terms represents. The mean, also known as the average, is the sum of all the values divided by the total number of values. To find the mean, add up all of the values and divide by the number of values. The median is the middle value in a set of data when it is arranged in order from least to greatest. The mode is the value that occurs most frequently in a set of data. Here's an example to illustrate these concepts:

Let's say we have a set of data consisting of the following values: 2, 5, 5, 7, 8, 10, 12. To find the mean, we add up all of the values and divide by the number of values. In this case, the sum of the values is 49 (2+5+5+7+8+10+12) and there are 7 values, so we divide 49 by 7 to get the mean, which is approximately 7. To find the median, we first need to arrange the data in order from least to greatest: 2, 5, 5, 7, 8, 10, 12. The middle value is 7, so that is the median. To find the mode, we look for the value that occurs most frequently. In this case, 5 occurs twice, which is more than any other value, so the mode is 5.
In conclusion, the mean, median, and mode are all measures of central tendency that can be used to describe a set of data. The mean is the average value, the median is the middle value, and the mode is the value that occurs most frequently. When calculating these measures, it is important to carefully consider the data and choose the appropriate method for finding each value.

The interval which the function is negative is (-∞, -6)

The equation of the function is given as:

\(g(x) = \sqrt[3]{x + 6}\)

When the function is negative.

It means that g(x) is less than 0

i.e. g(x) < 0

So, we have:

We can think of k as an unknown number.

8×_=2.00

12×_=3.00

20×_=5.00

If we divide 2 with 8 we are left with 0.25.

It's the same for the other numbers so we know the constant is 0.25.

When we use the formula y=0.25x with the numbers above, it is correct.

a) The probability of having at least 1 rotten strawberry among the 5 is 0.262.

b) 1 strawberry must be picked so that the probability of having exactly 2 rotten strawberries among them equals 2/35.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

The probability that Kyle selects exactly k rotten strawberries among the five she randomly picks is -

P( exactly k rotten strawberries) = \(\frac{(^2c_k)(^{34}c_{5-k}) }{^{36}c_5}\)

since if she picks k of the 2 rotten strawberries, Kyle must also select 5 - k of the 36 -2 = 34 good strawberries.

Therefore, the probability that Kyle picks at least one rotten strawberry is -

P(at least 1 rotten strawberry) = P(exactly 1 rotten strawberry) + P(exactly 2 rotten strawberries)

P(at least 1 rotten strawberry) =\(\frac{(^2c_1)(^{34}c_{4}) }{^{36}c_5} + \frac{(^2c_2)(^{34}c_{3}) }{^{36}c_5}\)

P(at least 1 rotten strawberry) = [(2 × 46376) / 376992] + [(1 × 5984) / 376992]

P(at least 1 rotten strawberry) = (92752 / 376992) + (5984 / 376992)

P(at least 1 rotten strawberry) = 0.246 + 0.016

P(at least 1 rotten strawberry) = 0.262

The probability of selecting exactly 2 rotten strawberries among n is

P(exactly 2 rotten strawberries) = \(\frac{(^2c_2)(^{34}c_{n-2}) }{^{36}c_n} = \frac{(^{34}c_{n-2}) }{^{36}c_n}\)

The value for n is 2/35.

P(exactly 2 rotten strawberries) =\(\frac{(^{34}c_{\frac{-33}{35}}) }{^{36}c_{\frac{2}{35} }}\)

P(exactly 2 rotten strawberries) = 1 / 1

P(exactly 2 rotten strawberries) = 1

Therefore, the probability is 0.262 and 1 strawberry must be picked.

As a result, the answer to the given angle problem can be found by comparing the position, measurement, and congruence of two or more angles.

When two lines come together at a common point, an angle is created. They are expressed as a number of degrees, denoted by the symbol °. Acute, right, obtuse, and reflex angles are the other three significant types of angles. 360 degrees make up a circle. A 720° angle indicates that the object has completed two full rotations.

Here,

You can compare angles and take into account their relationships to other angles in addition to calculating degrees or radians.

Since we are comparing the position, measurement, and congruence of two or more angles, we refer to them as having "angle relationships."

For instance, two lines or line segments that cross each other create two pairs of vertical angles.

When a transversal intersects two parallel lines, complex angle relationships, such as alternating interior angles, matching angles, and so forth, result.

Answer:

The orthocenter of triangle XYZ is (-6,4).

Step-by-step explanation:

To find the orthocenter of triangle XYZ, we need to first find the altitudes of the triangle.

The altitude of a triangle is a line that passes through a vertex of the triangle and is perpendicular to the opposite side.

Let's find the equation of the line passing through X(-9,5) and perpendicular to YZ. The slope of YZ is (8-3)/(-6+6) = 5/0, which is undefined. Therefore, YZ is a vertical line passing through the point (-6,3). The equation of this line is x=-6.

The line passing through X(-9,5) and perpendicular to YZ must be a horizontal line passing through X. Therefore, the equation of this line is y=5.

Similarly, the equation of the line passing through Y(-6,8) and perpendicular to XZ is x=-6.

The equation of the line passing through Z(-6,3) and perpendicular to XY is y=3.

Now, we need to find the intersection of these lines to find the vertices of the triangle's altitude.

The altitude from X passes through the point X(-9,5) and is perpendicular to the line YZ with equation x=-6. Therefore, the intersection of the altitude from X and YZ must have x-coordinate -6. Since the equation of the altitude from X is y=5, we get the point of intersection as (-6,5).

Similarly, the altitude from Y passes through the point Y(-6,8) and is perpendicular to the line XZ with equation x=-6. Therefore, the intersection of the altitude from Y and XZ must have x-coordinate -6. Since the equation of the altitude from Y is y=8, we get the point of intersection as (-6,8).

The altitude from Z passes through the point Z(-6,3) and is perpendicular to the line XY with equation y=3. Therefore, the intersection of the altitude from Z and XY must have y-coordinate 3. Since the equation of the altitude from Z is x=-6, we get the point of intersection as (-6,3).

Now that we have the vertices of the altitudes, we can find the equation of the lines passing through them.

The line passing through (-6,5) and (-6,8) is the line x=-6.

The line passing through (-6,5) and (-6,3) is the line y=4.

The line passing through (-6,8) and (-6,3) is the line x=-6.

Now, we find the intersection of the lines x=-6 and y=4. The intersection point is (-6,4).

Therefore, the orthocenter of triangle XYZ is (-6,4).

Step-by-step explanation:

If you have the same denominator, you can just subtract the numerators normally and carry over the denominator.

Answer:

A. \(n=100\)
B. \(k=0\)

Step-by-step explanation:

A. The equation "110% n = 11" can be solved as follows:

110% n = 11

To solve for n, we need to get rid of the percentage sign (%). We can do this by dividing both sides of the equation by 110%, or 0.110 (since 110% is equivalent to 1.1 in decimal form).

(110% n) / 110% = 11 / 110%

n = 11 / 0.110

n = 100

So, the solution for n in the equation "110% n = 11" is n = 100.

B. The given equation is:

(328 x 128) x k = 328 x (82 x 128) x k

To solve for k, we can simplify the equation using the properties of multiplication.

Step 1: Perform the multiplications inside the parentheses:

41984 x k = 328 x 10576 x k

Step 2: Rearrange the equation by applying the associative property of multiplication:

41984 x k = 328 x (10576 x k)

Step 3: Divide both sides of the equation by 328:

(41984 x k) / 328 = 10576 x k

Step 4: Cancel out the common factor of k on the left-hand side:

(41984 / 328) x k = 10576 x k

Step 5: Simplify the left-hand side:

128 x k = 10576 x k

Step 6: Subtract 10576 x k from both sides of the equation to isolate k:

128 x k - 10576 x k = 0

Step 7: Factor out k on the left-hand side:

k x (128 - 10576) = 0

Step 8: Simplify further:

k x (-10448) = 0

Step 9: Divide both sides of the equation by (-10448):

k = 0

So, the solution for k in the equation "(328 x 128) x k = 328 x (82 x 128) x k" is k = 0.

9 integers between 2023 and 5757 that have 12, 20, and 28 as factors.

Step-by-step explanation:

An integer that has 12, 20, and 28 as factors must be divisible by the least common multiple (LCM) of these numbers. The LCM of 12, 20, and 28 is 420. So we need to find the number of integers between 2023 and 5757 that are divisible by 420.

The first integer greater than or equal to 2023 that is divisible by 420 is 5 * 420 = 2100. The last integer less than or equal to 5757 that is divisible by 420 is 13 * 420 = 5460. So the integers between 2023 and 5757 that are divisible by 420 are 2100, 2520, ..., 5460. This is an arithmetic sequence with a common difference of 420.

The number of terms in this sequence can be found using the formula for the nth term of an arithmetic sequence: an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, d is the common difference, and n is the number of terms. Substituting the values for this sequence, we get:

5460 = 2100 + (n - 1)420 3360 = (n - 1)420 n - 1 = 8 n = 9

So there are 9 integers between 2023 and 5757 that have 12, 20, and 28 as factors.
