The largest head diameter that can accommodate the clientele is 8.5743

Mean, u = 6.4

Standard deviation = 0.9

We must utilize the inverse of the common normal table to obtain our values.

the smallest head width possible.

P(Z < z) = 1.4%

P(Z < z) = 0.014

P(Z < -2.0749) = 0.014

z = -2.0749

Using the z-score calculation,

(x - μ) ÷ σ = \(Z_{0.019}\)

Let x be the heads' breath.

Making x the focus of the equation,

x = z × σ + μ

We already have:

z = -2.0749

u = 6.5

s.d = 1

Replacing numbers,

x = (-2.0749 × 1) + 6.5

x = 4.4251

The clientele requires a minimum head breadth of 4.4251.

The largest head width that can be accommodated.

P(Z > z) = 1.4%

1 - P(Z < z) = 0.014

P(Z < z) = 1 - 0.014 = 0.981

P(Z < 2.0749) = 0.981

Using the z-score calculation,

(x - μ) ÷ σ = \(Z_{0.019}\)

Let x be the heads' breath.

Making x the focus of the equation,

x = z × σ + μ

z = 2.0749

u = 6.5

s.d = 1

Substituting figures,

x = (2.0749 × 1) + 6.5

x = 4.4251

Answer:

-2

Step-by-step explanation:

because it is on the -2 area

Step-by-step explanation:

In a parallelogram, opposite sides are equal and parallel. Therefore,

QT = PS = 3y ...(1)

PT + TR = PS

y + 2x + 1 = 3x + 9

2x - y = 4 .....(2)

PR = QT = 3y

PR = SQ = 3x + 9 ....(3)

From equations (1) and (3), we can see that:

3y = 3x + 9

y = x + 3

Substitute this value of y in equation (2):

2x - (x + 3) = 4

x = 7

To find the value of y, we can substitute x = 7 in equation (2):

2(7) - y = 4

y = 10

Therefore, x = 7 and y = 10.

Using the probability formula the value for the largest piece is obtained as 3/4.

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.

Let X be the length of the largest piece when a unit stick is broken into three random pieces.

We want to find E(X), the expected value of X.

To solve for E(X), we can use the law of total probability and consider all possible lengths for the first cut.

Let Y be the length of the first piece, which can take any value between 0 and 1.

Then, we can write -

E(X) = ∫[0,1] E(X|Y=y) fY(y) dy,

where fY(y) is the probability density function of Y and E(X|Y=y) is the expected value of X given that the first piece has length y.

Now, let's consider the possible cases for the lengths of the other two pieces -

If the second cut is made in the interval [0,Y], then the largest piece has length Y.

If the second cut is made in the interval [Y,1-Y], then the largest piece has length 1-Y.

If the second cut is made in the interval [1-Y,1], then the largest piece has length Y.

Therefore, we can write -

E(X|Y = y)

= y × 1 + (1 - y) × 1/2 + (1 - y)×1  

= 1/2 + y/2.

Substituting this into the previous formula and using the fact that the density function for a uniform distribution on [0,1] is fY(y) = 1 for 0 ≤ y ≤ 1, we get -

E(X) = ∫[0,1] (1/2 + y/2) dy

= [y^2/4 + y/2] from 0 to 1

= 3/4.

Therefore, the expected length of the largest piece is 3/4.

Answer:

C

Step-by-step explanation:

The value of mean, variance and covariance matrix is illustrated in following solution as

\(V(\frac{X}{X'} )=\left[\begin{array}{ccc}\frac{1}{12} &\frac{1}{12} \\\frac{1}{12} &\frac{4}{45} \\\end{array}\right]\)

The mean vector consists of the means of each variable and the variance-covariance matrix consists of the variances of the variables along the main diagonal and the covariances between each pair of variables in the other matrix positions. with \bar{x} and \bar{y} denoting the means of X and Y, respectively.

Mean and variance is a measure of central dispersion. Mean is the average of given set of numbers. The average of the squared difference from the mean is the variance. Central dispersion tells us how the data that we are taking for observation are scattered and distributed.

To find the mean, variance and covariance matrix of a random vector

\(\left[\begin{array}{ccc}X\\X'\\\end{array}\right]\) X~ U(0,1)

\(E(X')=\int\limits^1_0 {r} \, dr = \frac{1}{r+1}\)

where, r = 1 , 2, 3...

Now,

\(E(X) = \frac{1}{2}\\ \\E(X^2) = \frac{1}{3}\\ \\E(X^3) =\frac{1}{4}\\\)

\(E(X^4)=\frac{1}{5}\)

So, cov(X , X') =

\(E(X^3)-E(X).E(X')\\\\=\frac{1}{4} -\frac{1}{2}.\frac{1}{3}\\ \\ =\frac{1}{12}\)

\(Var(X) = E(X^4) -E'(X')\\\\\frac{1}{5}-\frac{1}{9}\\ \\ \frac{4}{45}\)

Hence,

\(V(\frac{X}{X'} )=\left[\begin{array}{ccc}\frac{1}{12} &\frac{1}{12} \\\frac{1}{12} &\frac{4}{45} \\\end{array}\right]\)

Step-by-step explanation:

The net for a triangular prism consists of a central rectangle and two triangles. The length of the central rectangle is equal to the perimeter of the triangular faces.

__

The area of the central rectangle of the net is ...

  A = LW = (12 +7 +10 ft)(6 ft) = 174 ft²

The two triangles are right triangles, so the area of each is half the product of the leg lengths.

  A = 1/2(bh) = 1/2(10 ft)(7 ft) = 35 ft²

Then the sum of the rectangle and two triangles is ...

  surface area = 174 ft² +2 × 35 ft² = 244 ft²

Answer:

-1/2, 5/3

Step-by-Step Explanation:

6z^2 - 7z - 5 = 0

The total cost of Jamie's brunch with a 20% tip is $20.94.

To calculate the total cost of Jamie's brunch with a 20% tip, we need to add the tip amount to the

Total cost refers to the sum of all costs associated with a particular item or project, including direct costs (such as materials and labor) and indirect costs (such as overhead and administrative expenses). It is the complete expense incurred in producing or acquiring something, including all fixed and variable costs.

Tip amount = 20% of the bill amount

\(= 20/100 * $17.45\)

\(= $3.49\)

Total cost = Bill amount + Tip amount

\(= $17.45 + $3.49= $20.94\)

Therefore, the total cost of Jamie's brunch with a 20% tip is $20.94.
