Area of Circle: $\pi r^{2}$

radius 'r' = 4ft (radius is half of diameter)
$\pi =3.14$

Area equals = 3.14 (4)^2 = 50.24 square feet = 50.2 square feet

Hope that helps!

The Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century

ira [324]

The probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

<h3>What is the Venn diagram?</h3>

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

f = 100 stamps in the collection

A = stamps in the 20th century

B = British stamps

We can make a linear equation to solve for x as the total stamps are 100 in the collection.

$\rm x(x-6)+x+2x+32= 100\\\\\rm x^2-6x+x+2x+32 = 100\\\\\rm x^2-3x-68 = 0$

After solving x = 9.88, or x = -6.88

Probability can't be negative so neglecting the negative ones

x = 9.88

The probability that it is British:

$=\rm \frac{x +2x + 32}{100}$

$=\rm \frac{9.88 +2(9.88) + 32}{100}$

= 61.64/100

= 0.6164

Thus, the probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

I dint want you to answer can you just explain to me how I can answer this because my teacher doesn't explain

VARVARA [1.3K]

Answer:

Train B is traveling faster.

Step-by-step explanation:

To find which train is faster, divide the distance the train traveled by the elapsed time for each train:

Train A:

Distance traveled is 12.5 meters.

Elapsed time is 1 second.

12.5 ÷ 1 = 12.5

Train A travels 12.5 meters per second.

Train B:

Distance traveled is 100 meters.

Elapsed time is 4 seconds.

100 ÷ 4 = 25

Train B travels 25 meters per second.

25 is greater than 12.5, so train B travels faster.

Consider the experiment where a pair of fair dice is thrown. Let X denote the random variable whose value is determined by takin

m_a_m_a [10]

Answer:

P(X=1) = 1/36

P(X=2) = 3/36 = 1/12

P(X=3) = 5/36

P(X=4) = 7/36

P(X=5) = 9/36 = ¼

P(X=6) = 11/36

7/36

Step-by-step explanation:

Attached, you will find a table with the possible values of X.

(See table attached)

As we can see, there are 36 entries so,

P(X=1) = 1/36

P(X=2) = 3/36 = 1/12

P(X=3) = 5/36

P(X=4) = 7/36

P(X=5) = 9/36 = ¼

P(X=6) = 11/36

It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so

P(X divisible by 4) = P(X=4) = 7/36
