Find the critical value zc necessary to form a confidence interval at the level of confidence shown below. c=0.80

The ommitted distribution :

C : ___ 0 ____ 1 ____ 2 ____ 3

P(C) :_0.05 _ 0.10 _ 0.75 _ 0.10

Answer:

0.19

Step-by-step explanation:

Given the table :

C : ___ 0 ____ 1 ____ 2 ____ 3

P(C) :_0.05 _ 0.10 _ 0.75 _ 0.10

The mean of the distribution is defined as :

ΣX * p(X)

Therefore ;

Σ(C * P(C))

= (0*0.05) + (1*0.10) + (2*0.75) + (3*0.10)

= 0 + 0.10 + 1.50 + 0.30

= 1.90

The mean, also the expected value gives the average number of coffee sold.

Answer:

X = 6

Step-by-step explanation:

2x + (-6x) = -24

2x - 6x = -24

-4x = -24

4x = 24

x = 6

Answer:

Step-by-step explanation:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1.) Simplify both sides of the equation

2x − 6x = −24

2x + −6x = −24

Then, Combine Like Terms

(2x+ −6x) = −24

−4x = −24

−4x = −24

2.) Divide both sides by -4

−4x /−4  =  −24 /−4

Which then gets you x = 6

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Good Luck.

Answer:

x = 84/5 = 16.8

Step-by-step explanation:

The angle bisector theorem said that

21/15 = x/12

==> 7/5 = x/12

==> x = 84/5

Answer:

[tex]\huge\boxed{\sf 8295 \ g}[/tex]

Step-by-step explanation:

= 8 kg 295 g

We know that 1 kg = 1000 g

So, 8 kg = 8 * 1000 g

= (8 * 1000) g + 295 g

= 8000 g + 295 g

= 8295 g

Answer:

6 - 4[tex]\sqrt{2}[/tex]

Step-by-step explanation:

To evaluate, substitute x = - 1 + [tex]\sqrt{2}[/tex] into f(x)

f(- 1 + [tex]\sqrt{2}[/tex] )

= (- 1 + [tex]\sqrt{2}[/tex] )² - 2(- 1 + [tex]\sqrt{2}[/tex] ) + 1 ← expand squared factor using FOIL

= 1 - 2[tex]\sqrt{2}[/tex] + 2 + 2 - 2[tex]\sqrt{2}[/tex] + 1 ← collect like terms

= 6 - 4[tex]\sqrt{2}[/tex]

Step-by-step explanation: Present: Ishaan = Christopher + 20       - Equation 1

1 years back: Ishaan-14 = 3(Christopher-14)    - Equation 2

Solve above equations:

I = 3c-42+14

I = 3c-24

I = c+20

2c-44 = 0

Christopher = 22  then from Equation 1

Ishaan = 22 + 20 = 42

Answer:

51.63m^3

Step-by-step explanation:

The figure is made up of a rectangle, triangle and a semi circle

Area of the figure = Area of triangle + rectangle + semicircle

Area of the triangle = 1/2 * base * height

Area of the triangle = 1/2 * 3 * 5

Area of the triangle = 15/2

Area of the triangle = 7.5m^3

Area of the rectangle = Length * Width

Area of the rectangle = 6 * 5

Area of the rectangle = 30m^2

Area of the semicircle = πr²/2

Area of the semicircle = π(3)²/2

Area of the semicircle = 3.14(9)/2

Area of the semicircle = 3.14 * 4.5

Area of the semicircle = 14.13m^2

The area = 30 + 14.13+7.5

Area of the figure = 51.63m^3

51.63m²

Answer:

[tex]\frac{27a^9 * 18b^5 * 4c^2 }{18a^4 * 12b^2 * 2c} = \frac{9}{2}a^5b^3c[/tex]

Step-by-step explanation:

Given

[tex]\frac{27a^9 * 18b^5 * 4c^2 }{18a^4 * 12b^2 * 2c}[/tex]

Required

Simplify

[tex]\frac{27a^9 * 18b^5 * 4c^2 }{18a^4 * 12b^2 * 2c}[/tex]

Cancel out 18

[tex]\frac{27a^9 * b^5 * 4c^2 }{a^4 * 12b^2 * 2c}[/tex]

Divide 4 and 2

[tex]\frac{27a^9 * b^5 * 2c^2 }{a^4 * 12b^2 *c}[/tex]

Divide 27 and 12 by 3

[tex]\frac{9a^9 * b^5 * 2c^2 }{a^4 * 4b^2 *c}[/tex]

Apply law of indices

[tex]\frac{9a^{9-4} * b^{5-2} * 2c^{2-1} }{4}[/tex]

[tex]\frac{9a^5 * b^3 * 2c }{4}[/tex]

Divide 2 and 4

[tex]\frac{9a^5 * b^3 * c}{2}[/tex]

[tex]\frac{9a^5b^3c}{2}[/tex]

Rewrite as:

[tex]\frac{9}{2}a^5b^3c[/tex]

Hence:

[tex]\frac{27a^9 * 18b^5 * 4c^2 }{18a^4 * 12b^2 * 2c} = \frac{9}{2}a^5b^3c[/tex]
