Answer:

A. 24 ≤ a < 26.

B. 22.5

Step-by-step explanation:

A. Determination of the modal class interval.

Mode is the class with the highest frequency.

From the table given above, the highest frequency is 8, therefore the class will the highest frequency is:

24 ≤ a < 26.

B. To obtain the mean, we must determine the class mark. This is illustrated below:

Class >>>>> class mark >>> frequency

18 – 19 >>>> 18.5 >>>>>>>>> 3

20 – 21 >>> 20.5 >>>>>>>> 2

22 – 23 >>> 22.5 >>>>>>>> 7

24 – 25 >>> 24.5 >>>>>>>> 8

26 >>>>>>>> 26 >>>>>>>>> 0

The mean is given by the summation of the product of the class mark and frequency divided by the total frequency. This is illustrated below:

Mean = [(18.5x3) + (20.5x2) + (22.5x7) + (24.5x8) + (26x0)] / (3+2+7+8+0)

Mean = (55.5 + 41 + 157.5 + 196 + 0)/20

Mean = 450/20

Mean = 22.5

Therefore, the mean age is 22.5

Answer:

23

Step-by-step explanation:

To work out the mean estimate you need to devide

(sum of midpoint x frequency) by (sum of frequency).

Sum of Frequency:

3+2+7+8+0

= 20

sum of (MPF):

Frequency x Midpoint

3x19=57

2x21=42

7x23=161

8x25=200

0x27=0

57+42+161+200+0

= 460

Mean Estimate:

The determinant of a 4x4 matrix is calculated using the Laplace Expansion method, which involves expanding the determinant along one row or column.

The formula for the determinant of a 4x4 matrix is:det(A) =\(a11 * a22 * a33 * a44 – a11 * a22 * a34 * a43 + a11 * a23 * a34 * a42 – a11 * a23 * a32 * a44 + a12 * a23 * a32 * a44 – a12 * a23 * a34 * a41 + a12 * a21 * a34 * a43 – a12 * a21 * a33 * a44 + a13 * a21 * a33 * a44 – a13 * a21 * a34 * a42 + a13 * a22 * a34 * a41 – a13 * a22 * a31 * a44 + a14 * a22 * a31 * a43 – a14 * a22 * a33 * a41 + a14 * a23 * a33 * a42 – a14 * a23 * a31 * a42\)To calculate the determinant of a 4x4 matrix, take the sum of the products of the elements in each row/column and its corresponding minor, then multiply each product by the sign of the term (+ or -). For example, if A is a 4x4 matrix, then the determinant is: det(A) =\(a11 * |A11| - a12 * |A12| + a13 * |A13| - a14 *\)|A14|.The minors A11, A12, A13 and A14 are the 3x3 matrices obtained by deleting the first row and first column from A. The values of the minors are calculated by applying the Laplace Expansion method to each minor.

Answer:

Step-by-step explanation:

Formula for calculating the surface area of the box S = 2(LW+LH+WH) where

L is the length of the box

W is the width of the box

H is the height of the box

If the box is square based with dimension 4 * 4in, then L = W = 4in. substituting this values given into the formula we will have;

S = 2(4(4)+4H + 4H)

S = 2(16+8H)

S = 32+16H

Hence, The function that represents the surface area of this box as a

function of its height is S = 32+16H where H is the height of the box

Given H = 6.5in, to evaluate the function, we will substitute h = 6.5in into the modeled equation;

S = 32+16H

S = 32+16(6.5)

S = 32+106

S = 138in²

100% humidity is very common in many coastal zones, near rivers or   lakes or in your bathroom when you take a shower, and possibly in  Alaska as well as UAE.

Relative humidity:

                             Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 % relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain — it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.

0% humidity means there is an absence of water vapor in the air.

Answer:

\(\displaystyle{P(x)=x^3-x^2}\)

Step-by-step explanation:

Given the zeros of 0, 0, 1. We can write the polynomial in form of x-intersects:

\(\displaystyle{P(x) = (x-x_1)(x-x_2)(x-x_3)}\)

Hence:

\(\displaystyle{P(x)=(x-0)(x-0)(x-1)}\)

Which can be simplified to:

\(\displaystyle{P(x)=x\cdot x \cdot (x-1)}\\\\\displaystyle{P(x)=x^2(x-1)}\)

Convert to the standard form by distributing x²:

\(\displaystyle{P(x)=x^2\cdot x - x^2 \cdot 1}\\\\\displaystyle{P(x)=x^3-x^2}\)

The radius of the silo which is in the shape of cylinders and spheres  , correct to the nearest tenth of a foot, is approximately 10.3 feet.

To find the radius of the silo, we need to determine the radius of the cylindrical section.

The volume of the cylindrical section can be calculated using the formula:

\(V_{cylinder} = \pi * r^2 * h\)

where \(V_{cylinder}\) is the volume of the cylindrical section, r is the radius of the cylindrical section, and h is the height of the cylindrical section.

Given that the cylindrical section is 30 ft tall, we can rewrite the formula as:

\(V_{cylinder} = \pi * r^2 * 30\)

To find the radius, we can rearrange the formula:

\(r^2 = V_{cylinder} / (\pi * 30)\)

Now, we can substitute the total volume of the silo, which is 10,000 cubic feet, and solve for the radius:

\(r^2 = 10,000 / (\pi * 30)\)

Simplifying further:

\(r^2 = 106.103\)

Taking the square root of both sides, we find:

\(r = \sqrt{106.103} = 10.3\)

Therefore, the radius of the silo which is in the shape of cylinders and spheres  , correct to the nearest tenth of a foot, is approximately 10.3 feet.

The answer is D. None of the above, the long-term DPMO is 25137, which is equivalent to a Z-value of 3.46. The short-term Z-value is usually 1.5 to 2 times the long-term Z-value,

so it would be between 5.19 and 6.92. However, these values are not listed as answer choices. The Z-value is a measure of how many standard deviations a particular point is away from the mean. In the case of DPMO, the mean is 6686. So, a Z-value of 3.46 means that the long-term defect rate is 3.46 standard deviations away from the mean.

The short-term Z-value is usually 1.5 to 2 times the long-term Z-value. This is because the short-term process is more variable than the long-term process. So, the short-term Z-value would be between 5.19 and 6.92.

Note that based on the quartiles the estimated number  of rides less that 6.5 minutes long is about about 5 rides.

To  estimate the number of rides that would  be less than 6.5 minutes long, we can make use of the  interquartile range (IQR).

Assumption -  Data is Symmetrically distributed.

Recall  that IQR is the variance between the first quartile (Q1) and the third quartile  (Q3).

So IQR =   Q3 - Q1

= 10 minutes - 6.5 minutes

= 3.5 minutes

Based on the assumption above  we can consider Q2 as the 50th percentile.

Thus, to estimate the number of rides that would be less than 6.5 minutes long, use the Z-score formula:

Z = (X - μ) / σ

Where:

Z is the Z-score,

X is the value we want to estimate (6.5 minutes),

μ is the mean of the data (which we assume to be Q2),

σ is the standard deviation of the data (which we assume to be IQR / 1.35).

NOte: The factor 1.35 is an approximation for converting the IQR to the standard deviation of a  normal distribution

Z = (6.5 -8) / (3.5 /1.35)

= - 0.5 / 2.59    

 =  -0.57857142857

≈ - 0.58

Based on  statistical calculator,  the proportion of data that falls below a Z-score o - 0.58, which represents the expected number of rides that would be less than 6.5 minutes long, is

= 0.2787.

Thus, te estimated number of rides less than 6.5 minutes long ≈ 0.2787 * 16

= 4.4592

≈ 4.5 rides

Thus we can expect the 4 or 5 rides to be less than 6.5 minutes long.

It is true that the compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group are indeed called alcohols.

Alcohols are a class of organic compounds that contain one or more hydroxyl (-OH) groups attached to a hydrocarbon chain. The hydroxyl group replaces one or more hydrogen atoms in an alkane, resulting in the formation of an alcohol. This substitution of a hydrogen atom with an -OH group introduces the characteristic properties and reactivity of alcohols, including their ability to form hydrogen bonds, undergo oxidation reactions, and participate in various chemical reactions.

The presence of the hydroxyl group also imparts certain physical properties to alcohols, such as higher boiling points and water solubility compared to their corresponding hydrocarbons. Overall, the presence of the -OH group distinguishes alcohols from other organic compounds and gives them their unique properties and characteristics.

To find arbitrarily large powers of s without doing matrix multiplication, we can use the binary representation of the power and exponentiation by squaring.

Exponentiation by squaring is a method for computing large powers of a number efficiently. To compute s^n, we first convert n to its binary representation. For example, if we want to compute s^13, we first convert 13 to its binary representation of 1101, which is equivalent to 8 + 4 + 1.

We then compute s^8, s^4, and s^1, and multiply them all together. To compute s^8, we use the fact that s^8 = (s^4)^2. To compute s^4, we use the fact that s^4 = (s^2)^2. To compute s^2, we use the fact that s^2 = s*s.

We continue in this way until we have computed the powers of all the individual binary digits, and then multiply them all together to get s^13. This method is much more efficient than computing the powers directly by multiplying s by itself 13 times.

Standard hyperbola through origin when values of x for the vertices are equal. \($\frac{y^2}{b^2}-\frac{x^2}{a^2}=1$\)

Now solve the asymptotes \($\mathrm{y}=3 \mathrm{x}-6$\) and \($\mathrm{y}=-3 \mathrm{x}$\)

The two right inverse functions of f are g(x)=x−1 and h(x)=−x−1. Both functions map from [1,∞) to R, and they both satisfy f(g(x))=f(h(x))=x for all x∈[1,∞).

A right inverse function of f is a function g such that f(g(x))=x for all x in the domain of f. In this case, the domain of f is R, and the range of f is [1,∞).

We can see that g(x)=x−1 is a right inverse function of f because f(g(x))=f(x−1)=x−1+1=x for all x∈[1,∞). Similarly, h(x)=−x−1 is also a right inverse function of f because f(h(x))=f(−x−1)=x−1+1=x for all x∈[1,∞).

The fact that f has two different right inverse functions shows that it is not injective. An injective function has a unique right inverse function. However, a surjective function always has at least one right inverse function.
