Answer:

a.0.5984

b.0.2394

c.0

d.13.4

Step-by-step explanation:

We are given that

a=6.3,b=20.5

The pdf of uniform distribution

[tex]f(x)=\frac{1}{b-a}=\frac{1}{20.5-6.3}=0.0704[/tex],6.3<x<20.5

            0, otherwise

Now,

a.

P(10.2<x<18.7)=[tex]\int_{10.2}^{18.7}f(x) dx[/tex]

[tex]=0.0704[x]^{18.7}_{10.2}[/tex]

[tex]P(10.2<x<18.7)=0.0704(18.7-10.2)=0.5984[/tex]

b.P(x>17.1)

[tex]P(x>17.1)=\int_{17.1}^{20.5}0.0704dx[/tex]

[tex]=0.0704(20.5-17.1)[/tex]

[tex]=0.2394[/tex]

c.P(x<6.3)=0

d.E[x]=[tex]\frac{a+b}{2}=\frac{6.3+20.5}{2}=13.4[/tex]

Answer:

Y= 3/4x - 4

Step-by-step explanation:

Hey there!

The answer to your question is y = 3/4x - 4

We have to solve for y:

3x - 4y - 16 = 0

3x - 4y = 16

-4y = -3x + 16

y = 3/4x - 4

Answer:

First always the positive is greater than the negative

Then 1/2, 2, 21/2, 2, 11/2 are greater than - 1/2

1/2=0.5

21/2=10.5

11/2=5.5

Step-by-step explanation:

I think that is 52

Answer:

x=52

Step-by-step explanation:

180-112=68

use the equation :(n-2)x180

(6-2)x180=720

720/6=120

Answer:

x = 8.4

Step-by-step explanation:

In a right triangle, an angle, the length of its adjacent side and the length of the hypotenuse can be related by the cosine.

In this question:

Angle of 40º.

Adjacent side of x, hypotenuse of 11. So

[tex]\cos{40} = \frac{x}{11}[/tex]

Using a calculator, we have that [tex]\cos{40} = 0.766[/tex]. So

[tex]x = 11*0.766 = 8.4[/tex]

The answer is x = 8.4

Answer:

1.099 * 10^-8 ; 4.23 * 10^-5 ; 0.0036

Step-by-step explanation:

Given :

p = 0.6

Sample size, n = 20

P(x = 0)

Using binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

1 - p = 1 - 0.6 = 0.4

P(x = 0) = 20C0 * 0.6^0 * 0.4^20

P(x = 0) = 1 * 1 * 1.099511627776E−8

P(x = 0) = 1.099 * 10^-8

2) Exactly 3;

P(x = 3) = 20C3 * 0.6^3 * 0.4^17

P(x = 3) = 1140 * 0.216 * 0.00000017179869184

P(x = 3) = 0.0000423037098786816

P(x = 3) = 4.23 * 10^-5

3.) More than 17

P(x > 17) = P(x = 18) + P(x = 19) + P(x = 20)

Using calculator :

P(x > 17) = 0.0036

Answer:

525; $68.25

Step-by-step explanation:

21+.09x=.13x

x=525

21+.09(525)=68.25

.13(525)=68.25

The answers are :

A) The amount of calling for which the two plans cost the same will be 525 minutes.

B) The cost when two plans cost the same amount is $68.25.

What do you mean by algebraic expressions ?

Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.

A)

Let's assume the amount of calling is x for which the two plans cost the same.

So , the algebraic expression can be written as ;

Plan A = Plan B

or

21 + (0.09 × x) = 0 + (0.13 × x)

Solving this we will get amount of calling for which the two plans cost the same as :

21 = 0.13x - 0.09x

0.04x = 21

x = 525 minutes

B)

Now , the cost when two plans cost the same amount :

Plan A = 21 + (0.09 × 525) = 21 + 47.25 = $68.25

or

Plan A = Plan B = $68.25

Therefore , the answers are :

A) The amount of calling for which the two plans cost the same will be 525 minutes.

B) The cost when two plans cost the same amount is $68.25.
