The the diameter of the shaft is  to be in order to transmit 60 hp at 150 rpm 1.88 inch.

We must first obtain the formula for calculating horsepower.

The phrase to use is as follows:

hp = k  × v  × d³ ......eq(1)

Where:

Since k is a constant, it will always have the same value when the shaft is transferring 60 horsepower at 150 rpm.

Therefore, using the first set of information, we can determine the value of k and subsequently the diameter.

When we solve for k in (1), we get:

k = hp / (v × d³)

Put the values;

k = 45 / (100  × 3³)

k = 0.02

Put the value of k and solve for diameter.

d = ∛hp / (k   × v)

d = ∛60 / (150 × 0.06)

d = 1.88 inch

Thus, the the diameter of the shaft is  to be in order to transmit 60 hp at 150 rpm 1.88 inch.

Step-by-step explanation:

You can find mean by adding the total number of texts sent by each person and dividing it by the number of days.

In this case, the mean of Amara's texts sent is 6.714...

The mean of Marquis' texts sent is 9.428...

Therefore, Amara has the smaller mean.

The required percent of the total profit was not brought in by the sales department is 33%.

Simple Interest (S.I.) is the strategy for working out the premium sum for a specific chief measure of cash at some pace of revenue. For instance, when an individual takes a credit of Rs. 5000, at a pace of 10 p.a. for a considerable length of time, the individual's advantage for quite some time will be S.I. on the acquired cash.

profit amount = $1196.7

Amount used in sales =  $798.9

Amount was not used in sales = $1196.7 - $798.9 = $397.8

The probability that someone who tests positive has the genetic disease is  0.142

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Let E be the people test positive

Let F be the people who has disease

P(F)= 1/10000 = 0.0001

P(E/F)= 99.5% = 0.995

P(E/F bar ) = 0.06 % = 0.0006

Baye's theorem:

P(F/E) =  [ P(E/F) * P(F) ] /  [ P(E/F) * P(F) + P(E/F bar ) * P( F bar ) ]

conditional probability :

P(B/A) = P ( A [tex]\cap[/tex] B ) / P(A)

Complement rule is given  by:

P (F bar ) = 1 - P(F) = 1 - 0.0001 = 0.9999

The probability that someone who tests positive has the genetic disease :

P(F/E) =  [ P(E/F) * P(F) ] /  [ P(E/F) * P(F) + P(E/F bar ) * P( F bar ) ]

         = ( 0.995 * 0.0001 ) / ( 0.995 * 0.0001 + 0.0006 *0.9999)

What is normal distribution of probability?

Normal distribution of probability is a continuous type probability distribution whose probability density function is given by

f(x) = [tex]\frac{1}{\sigma \sqrt{2\pi}}e^{-\frac{z^2}{2}}[/tex] where z = [tex]\frac{x - \mu}{\sigma}[/tex]

[tex]\mu[/tex] is the mean and [tex]\sigma[/tex] is the standard deviation.

Here, normal distribution of probability is used

Mean = 69 inches

Standard deviation = 2.5 inches

P(64 < X < 66.5) = P(X <66.5) - P(X < 64)

For X < 64

z = [tex]\frac{64 - 69}{2.5}[/tex] = -2

P(X < 64) = P(z < -2) = 0.0228

For X < 66.5

z = [tex]\frac{66.5 - 69}{2.5}[/tex] = -1

P(X < 66.5) = P(z < -1) = 0.1587

P(64 < X < 66.5) = 0.1587 - 0.0228 = 0.1359

Step-by-step explanation:

Answer:

If you divide 76 by 6, you would get 12.6666667.

76 divided by 6 is equal to 12 and 2/3, or simply 12.67 when expressed as a decimal.

To divide 76 by 6, we perform the division operation to find the quotient.

When dividing, we start with the largest multiple of 6 that is less than or equal to 76, which is 72. We divide 72 by 6, which equals 12.

Next, we subtract the product of 6 and 12 from 76 to find the remainder:

76 - (6 x 12) = 76 - 72 = 4

Since there is still a remainder of 4, we can express the result as a mixed number: 12 and 4/6.

To simplify the mixed number, we can reduce the fraction. The greatest common divisor of 4 and 6 is 2, so we can divide both the numerator and denominator by 2:

4/2 ÷ 6/2 = 2/3

Therefore, 76 divided by 6 is equal to 12 and 2/3, or simply 12.67 when expressed as a decimal.

x = 0 is a vertical line. It's the y-axis.

One pipe takes 6 hours to fill the pool and the other takes 12 hours.

Pipe A fills 1/x of the pool per hour, and Pipe B fills 1/y of the pool per hour. In other words, A takes x hours to fill the pool and B takes y hours to fill the pool.

Together, they fill 1/x + 1/y of the pool per hour. So, 4 hours times that rate should equal 1 full pool, since together they take 4 hours to fill the pool. That gives you your first equation:

4(1/x + 1/y) = 1

You're also told that if one pipe fills half the pool and the other takes over to fill the rest, it will take 9 hours. We don't know how long Pipe A works, so call that number of hours t. Pipe B must work for 9 - t hours.

So, Pipe A, working for t hours, fills half the pool:

t(1/x) = 1/2

And Pipe B, working for 9 - t hours, fills half the pool:

(9-t)(1/y) = 1/2

You now have a system of three equations (because this is an exceptionally complicated pipe-filling-pool problem):

4(1/x + 1/y) = 1

t(1/x) = 1/2

(9-t)(1/y) = 1/2

Solve for t in that second equation, then plug it into the third equation:

t(1/x) = 1/2

t = x(1/2)

t = x/2

(9 - x/2)(1/y) = 1/2

Now you've got a system of two equations:

4(1/x + 1/y) = 1

(9 - x/2)(1/y) = 1/2

Solve for y in the second equation, then plug that into the first equation:

(9 - x/2)(1/y) = 1/2

(9 - x/2) = y(1/2)

2(9 - x/2) = y

18 - x = y    (this is a really nice-looking form of that equation; we'll use it again later)

4(1/x + 1/y) = 1

4(1/x + 1/(18-x)) = 1

4/x + 4/(18-x) = 1

(4(18-x))/(x(18-x)) + (4x)/(x(18-x)) = 1

(4(18-x) + 4x)/(x(18-x)) = 1

4(18-x) + 4x = x(18-x)

72 - 4x + 4x = 18x - x2

72 = 18x - x2

x2 - 18x + 72 = 0

(x - 6)(x - 12) = 0

x - 6 = 0    OR    x - 12 = 0

x = 6   OR    x = 12

So, Pipe A takes either x = 6 or x = 12 hours to fill the pool alone.

When Pipe A takes 6 hours to fill the pool, Pipe B takes 12. When Pipe A takes 12 hours to fill the pool, Pipe B takes 6.

These cases are equivalent, since the original problem makes no distinction between the pipes.

Hence, one pipe takes 6 hours to fill the pool and the other takes 12 hours.

What is meaning of discrete random variable?

A discrete random variable has a countable number of different possible values, such as 0,1,2,3,4, etc. Usually, but not always, discrete random variables are counts. A random variable is discrete if it can only take a finite number of different values.

Given table is

X        0         1          2        3

P(x)  0.72     0.11    0.02  

The sum of the probability of an event is 1.

Therefore

P(0) + P(1) + P(2) + P(3) = 1

Putting the value of P(0), P(1), P(2)

0.72 + 0.11 + 0.02 + P(3) = 1

0.85 + P(3) = 1

P(3) = 1- 0.85

P(3) = 0 .15

The mean of the discreate random variable is Σ xp(x) / Σ x

=[(0 × P(0)) + (1 × P(1)) + (2 × P(2)) + (3 × P(3))]/(0 + 1 + 2 + 3)

Let us consider,

Width of the printed part, in inches be 'x'

height of the printed part, in inches be 'y'

According to question,

Area of the printed part, in square inches = xy = 24

So,

y=24/x

width of the page, in inches = x + 2×1 = x+2

height of the page, in inches = y + 2×1.5 = y + 3

The area of the page (in square inches) is , A

= (x+2) (y+3)

= xy + 3x + 2y + 6

= 24 + 3x + 2y + 6

= 3x + 2y + 30

= 3x + 2×24/x + 30

= 3x + 48/x + 30

The minimum length can be found by calculating the derivative dA/dx, where A is the area of the paper

Solving the equation for dA/dx=0,

[tex] \frac{dA}{dx} = \frac{d(3x + \frac{48}{x} + 30)}{dx} [/tex]

[tex] \frac{dA}{dx} = 3 + \frac{48}{ {x}^{2} } [/tex]

[tex]\frac{dA}{dx} = 3 + \frac{48}{ {x}^{2} } = 0[/tex]

x = 4

then,

y = 24/4 = 6

The width and height of the paper are

x+2=4+2=6 and

y+3=6+3 =9

The dimensions of the page, so that the least amount of paper is used must be 6 inches wide by 9 inches tall.
