Answer:

[tex]A = 329.7[/tex]

Step-by-step explanation:

Given

[tex]h = 15[/tex] --- height

[tex]d = 7[/tex] --- diameter

Required

Paper needed to cover the sides

To do this, we simply calculate the surface area of the cylinder (without considering the top and bottom)

This is calculated as:

[tex]A = 2\pi rh[/tex]

Where

[tex]r = \frac{d}{2}[/tex]

[tex]r = \frac{7}{2}= 3.5[/tex]

The formula becomes

[tex]A = 2 * 3.14 *3.5 *15[/tex]

This gives:

[tex]A = 329.7[/tex]

Answer:

y = 4x - 3

Step-by-step explanation:

Find two point of the line

(0,-3) ; (1,1)

Use this formula

(y - y1)/(y2-y1) = (x-x1)/(x2-x1)

(y-(-3)/(1-(-3) = (x-0)/(1-0)

(y+3)/4 = x

y+3 = 4x

y = 4x -3

Answer:

y = 4x -3

Step-by-step explanation:

The y intercept is (0,-3)

Using another point on the line (1,1), we can find the slope

m = (y2-y1)/(x2-x1)

m = (1 - -3)/(1-0)

   = (1+3)/(1-0)

   = 4/1

The equation for a line in slope intercept for is

y = mx+b where m is the slope and b is the y intercept

y = 4x -3

Answer:

[tex]g=6x+18[/tex]

Step-by-step explanation:

From the question we are told that:

Function

 [tex]f(x)=x^3+9x^2−81x+14[/tex]

Generally 1st derivative f'(x) of Fuction f(x) is

 [tex]f'(x)=3x^2+2*9(x)-81[/tex]

 [tex]f'(x)=3x^2+18(x)-81[/tex]

Generally 2nd derivative f''(x) of Fuction f(x) is

Where

 [tex]f''(x)=g[/tex]

Therefore

 [tex]g=3x^2+18(x)-81[/tex]

 [tex]g=2*3x^1+18[/tex]

 [tex]g=6x+18[/tex]

Empty set

Step-by-step explanation:

The set containing no element in it is called​ an empty set.

One of the example of an empty set is as follows :

A = {x : x² = 4, x is odd}

In this case, if x = 2, then x² = (2)² = 4

There is no number other than 2 whose square is equal to 4.

Hence, this is an empty set.

Answer:

a) the probability of committing a type I error if the true proportion is p = 0.6 is 0.0548

b)

- the probability of committing a type II error for the alternative hypotheses p = 0.3 is 0.3504

- the probability of committing a type II error for the alternative hypotheses p = 0.4 is 0.6177

- the probability of committing a type II error for the alternative hypotheses p = 0.5 is 0.8281

Step-by-step explanation:

Given the data in the question;

proportion p = 0.6

sample size n = 10

binomial distribution

let x rep number of orders for raw materials arriving late in the sample.

(a) probability of committing a type I error if the true proportion is  p = 0.6;

∝ = P( type I error )

= P( reject null hypothesis when p = 0.6 )

= ³∑[tex]_{x=0[/tex] b( x, n, p )

= ³∑[tex]_{x=0[/tex] b( x, 10, 0.6 )

= ³∑[tex]_{x=0[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.6)^x[/tex][tex]( 1 - 0.6 )^{10-x[/tex]

∝ = 0.0548

Therefore, the probability of committing a type I error if the true proportion is p = 0.6 is 0.0548

b)

the probability of committing a type II error for the alternative hypotheses p = 0.3

β = P( type II error )

= P( accept the null hypothesis when p = 0.3 )

= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )

= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.3 )

= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.3)^x[/tex][tex]( 1 - 0.3 )^{10-x[/tex]

= 1 - ³∑[tex]_{x=0[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.3)^x[/tex][tex]( 1 - 0.3 )^{10-x[/tex]

= 1 - 0.6496

= 0.3504

Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.3 is 0.3504

the probability of committing a type II error for the alternative hypotheses p = 0.4

β = P( type II error )

= P( accept the null hypothesis when p = 0.4 )

= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )

= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.4 )

= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.4)^x[/tex][tex]( 1 - 0.4 )^{10-x[/tex]

= 1 - ³∑[tex]_{x=0[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.4)^x[/tex][tex]( 1 - 0.4 )^{10-x[/tex]

= 1 - 0.3823

= 0.6177

Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.4 is 0.6177

the probability of committing a type II error for the alternative hypotheses p = 0.5

β = P( type II error )

= P( accept the null hypothesis when p = 0.5 )

= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )

= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.5 )

= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.5)^x[/tex][tex]( 1 - 0.5 )^{10-x[/tex]

= 1 - ³∑[tex]_{x=0[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.5)^x[/tex][tex]( 1 - 0.5 )^{10-x[/tex]

= 1 - 0.1719

= 0.8281

Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.5 is 0.8281

The probability of committing a type I is 0.0548, type II error for  p = 0.3 is 0.3504, type II error for p = 0.4 is 0.6177, type II error for s p = 0.5 is 0.8281.

The sample size n = 10

Binomial distribution summarizes the number of trials, or observations when each trial has the same probability of attaining one particular value.

(a) Probability of committing a type I error if the true proportion is  p = 0.6;

∝ = P( type I error )

= P( reject null hypothesis when p = 0.6 )

[tex]\rm p= \left[\begin{array}{ccc}10\\x\\\end{array}\right] \times 0.6^{x} \times 0.6^{10-x}\\[/tex]

∝ = 0.0548

Therefore, the probability of committing a type I error if the true proportion is p = 0.6 is 0.0548

b) The probability of committing a type II error for the alternative hypotheses p = 0.3

β = P( type II error )

= P( accept the null hypothesis when p = 0.3 ) = ¹⁰∑

[tex]\rm p= \left[\begin{array}{ccc}10\\x\\\end{array}\right] \times 0.3^{x} \times 0.3^{10-x}\\[/tex]

= 1 - ³∑

= 1 - 0.6496

= 0.3504

Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.3 is 0.3504

The probability of committing a type II error for the alternative hypotheses p = 0.4

β = P( type II error )

= P( accept the null hypothesis when p = 0.4 )

[tex]\rm \left[\begin{array}{ccc}10\\x\\\end{array}\right] \times 0.4^{x} \times 0.4^{10-x}\\[/tex] = ¹⁰∑

= 1 - ³∑

= 1 - 0.3823

= 0.6177

Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.4 is 0.6177

The probability of committing a type II error for the alternative hypotheses p = 0.5

β = P( type II error )

= P( accept the null hypothesis when p = 0.5 )

¹⁰∑ = [tex]\rm \left[\begin{array}{ccc}10\\x\\\end{array}\right] \times 0.5^{x} \times 0.5^{10-x}\\[/tex]

Answer:

The smallest 5 digit number is 10,000 and the greatest 5 digit number is 99,999. There are 90,000 five-digit numbers in all.

Answer:

Step-by-step explanation:

We will use the idea here that the first 2 pipes can get 1/4 of the job done in an hour, and that the third pipe can get 1/3 of the job done in an hour. We need to know then the number of hours it will take to fill the tank if all 3 work together. The equation looks like this:

[tex]\frac{1}{4}+ \frac{1}{4}+ \frac{1}{3}= \frac{1}{x}[/tex] Now we find a common denominator and solve for x. The common denominator is 12x. Multiplying everything by 12 x gives us

3x + 3x + 4x = 12 and

10x = 12 so

x = 1.2 hours

Answer:

1.2 hours

Step-by-step explanation:

we need to see how much each pipes does in the same amount of time

The least common multiple of 3 hours and 4 hours is 12 hours

In 12 hours:

Pipe 1 at 4 hours to fill a tank fills 3 tanks

Pipe 2 at 4 hours to fill a tank fills 3 tanks

Pipe 3 at 3 hours to fill a tank fills 4 tanks

All three pipes can fill 10 tanks in 12 hours

12 hours/10 tanks = 1.2 hours to fill one tank

-------------------------

Doing just the math

1/4 + 1/4 + 1/3 = x

3/12 + 3/12 + 4/12 = 10tanks/12 hours

12hours/10tanks = 1.2 hours

GIVEN :-

TO FIND :-

FACTS TO KNOW BEFORE SOLVING :-

In a parallelogram , pair of opposite sides are always equal in length.

SOLUTION :-

PQRS will be a parallelogram only when :-

1) Assume that PQ = RS.

[tex]=> 2y + 3 = y + 5[/tex]

[tex]=> 2y - y = 5 - 3[/tex]

[tex]=> y = 2[/tex]

∴ For y = 2 , PQ = RS.

2) Now, assume that PS = QR.

[tex]=> 4x - 3 = 4y + 1[/tex]

(Put y = 2 in the equation)

[tex]=> 4x - 3 = 4 \times 2 + 1[/tex]

[tex]=> 4x - 3 = 9[/tex]

[tex]=> 4x = 9 + 3 = 12[/tex]

[tex]=> x = \frac{12}{4} = 3[/tex]

∴ For x = 3 , PS = QR.

CONCLUSION :-

For x = 3 & y = 2 , PQRS is a parallelogram.

Answer:

x = 22/3  y = 20/9

Step-by-step explanation:

2x-3y =8 x+3y=14

Add the two equations together to eliminate y

2x-3y =8

x+3y=14

-------------

3x +0y = 22

Divide each side by 3

3x/3 = 22/3

x = 22/3

Then take the second equation and multiply by -2 and add to eliminate x

2x-3y =8

-2x-6y=-28

----------------------

  -9y = -20

Divide by -9

-9y/-9 = -20/-9

y = 20/9

x = 22/3  y = 20/9

Answer:

perimeter is the length of all sides added together, since this a square and one side is 20 length, all sides must be 20 length. 20 + 20 + 20 + 20 = 80
