Sital is right
This is because there are 10mm in a cm so therefore you would times 2.5cm by 10 to get 25mm

Let X represent the time it takes from when someone enters the line for a roller coaster until they exit on the other side. Cons

Yuri [45]

Answer:

a. E(x) = 3.730

b. c = 3.8475

c. 0.4308

Step-by-step explanation:

Given

0 x < 3

F(x) = (x-3)/1.13, 3 < x < 4.13

1 x > 4.13

Calculating E(x)

First, we'll calculate the pdf, f(x).

f(x) is the derivative of F(x)

So, if F(x) = (x-3)/1.13

f(x) = F'(x) = 1/1.13, 3 < x < 4.13

E(x) is the integral of xf(x)

xf(x) = x * 1/1.3 = x/1.3

Integrating x/1.3

E(x) = x²/(2*1.13)

E(x) = x²/2.26 , 3 < x < 4.13

E(x) = (4.13²-3²)/2.16

E(x) = 3.730046296296296

E(x) = 3.730 (approximated)

What is the value c such that P(X < c) = 0.75

First, we'll solve F(c)

F(c) = P(x<c)

F(c) = (c-3)/1.13= 0.75

c - 3 = 1.13 * 0.75

c - 3 = 0.8475

c = 3 + 0.8475

c = 3.8475

What is the probability that X falls within 0.28 minutes of its mean?

Here we'll solve for

P(3.73 - 0.28 < X < 3.73 + 0.28)

= F(3.73 + 0.28) - F(3.73 + 0.28)

= 2*0.28/1.3 = 0.430769

= 0.4308 -- Approximated

Mr.Hershamn has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 2.6km by 4.37km. H

AVprozaik [17]

Answer:

11.362 sq km

1136.2 hectares

Step-by-step explanation:

Given that:

The farm is in the shape of a rectangle.

Dimensions of the rectangular shaped land = 2.6 km by 4.37 km

To find:

Area of land bought in square km and in hectares.

Solution:

First of all, let us have a look at the formula for area of a rectangular shape figure.

$Area = Length \times Width$

Here,

Length = 2.6 km

Width = 4.37 km

So, Area = $2.6 \times 4.37 = 11.362\ sq\ km$

To convert square kilometers to hectares, we can use the following conversion formula:

1 sq km = 100 hectares

11.362 km = 100 $\times$ 11.362 = 1136.2 hectares

HELP PLZ.....I NEED THIS....One wheel of a bicycle has 24-inch diameter. About how many feet will the bicycle travel when the wh

Ne4ueva [31]

First, find the circumference of the wheel using $C=2 \pi r$

You know that your diameter is 24. To find the radius, divide the diameter by 2, which is 12.

Input 12 as r and simplify. -> $C=2 \pi (12)$
$C=24 \pi$

estimate your Pi as 3.14
$C=24(3.14)$

and multiply. C=75.36

Now you know the distance of one full revolution in inches. To find 200 revolutions, multiply that answer by 200.

75.36 * 200 = 15,072 inches

But because this is in inches, you have to find the answer in feet, so just divide that answer by 12.

15,072 / 12 = 1,256 ft
