Apond contains 100 fish, ofwhich 30 are carp. If 20 fish are caught, what are the mean and variance of the number of carp among

Sergeu [11.5K]

Total fish = 100

Carp = 30

Number of fish caught = 20

The random variable X follows hyper-geometric distribution.

Mean = 30 *20 / 100 = 600/100 = 6

Variance = 30*20/100 * ((20-1)*(30-1)/100-1 + 1-30*20/100)

Variance = 600/100 * 56/99

Variance = 112/33

Assumptions: Is that X follows hyper-geometric distribution with the given information.

In chole’s closet there are 10 shirts and 15 shirts

olasank [31]

Shirts=10
Shorts=15

Ratio:-

10:15=2:3

Ratio of Chris=4:5

If we take decimals

2/3=0.6
4/5=0.8

Approximately they are equal

Compare adding unlike fractions and adding like fractions

muminat

Answer:

We just add numerators and rewrite denominator.

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

Step-by-step explanation:

You mean unlike denominators and like denominators.

Adding like dominators: We just add numerators and rewrite denominator :

Example : $\frac{1}{4} +\frac{2}{4}=\frac{1+2}{4} =\frac{3}{4}$

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

For example :

$\frac{1}{5}+\frac{3}{4}$

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

$\frac{1*4}{20} +\frac{3*5}{20}=\frac{4}{20} +\frac{15}{20}=\frac{19}{20}$

Twelve is added to the product of a number and 5. The result is -3.

sergey [27]

Answer:

The unknown number is -3

Step-by-step explanation:

Represent unknown as x

Write as an equation

12 + (x * 5) = -3

Multiply

12 + 5x = -3

Subtract -5x from both sides of the equation

12 = -3 - 5x

Add 3 to both sides of the equation

15 = -5x

Divide both sides by -5

x = -3

The unknown number is -3

Hope this helps :)
