$\\ \sf\longmapsto x^2=a$

$\\ \sf\longmapsto x=\sqrt{a}$

Now if a be 1,2,3,4....

$\\ \sf\longmapsto x=\sqrt{1}=1$

$\\ \sf\longmapsto x=\sqrt{2}$

$\\ \sf\longmapsto x=\sqrt{3}$

$\\ \sf\longmapsto x=\sqrt{4}=2$

And so on

How to do improper fractions with 3.8 repeating

vivado [14]

3.88888=3.88888/1=38.8888888

so lets ssay our repeating decimal = a fraction x
x=3.888 is true
multiply by 10
10x=38.8888
now subtract fir frist eqation from second
10x-x=38.8888-3.888888
9x=35
divide both sides by 9
x=35/9
x=3 and 7/9

anser is 3.88=3 and 7/9

Suppose that poaching reduces the population of an endangered animal by 6% per year. Further suppose that when the population o

artcher [175]

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500* $(1-0.06)^{n}$

20=1500* $0.94^{n}$

20/1500= $0.94^{n}$

0.133= $0.94^{n}$

take log both sides

log(0.133)=log $0.94^{n}$ -------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268

n=3.269

Hence to reach level of 20 the population takes 3.2 years.

A blue die and a red die are thrown. B is the event that the blue comes up with a 6. E is the event that both dice come up even.

iVinArrow [24]

Answer:

Size of |E n B| = 2

Size of |B| = 1

Step-by-step explanation:

I'll assume both die are 6 sides

Given

Blue die and Red Die

Required

Sizes of sets

- $|E\ n\ B|$

- $|B|$

The question stated the following;

B = Event that blue die comes up with 6

E = Event that both dice come even

So first; we'll list out the sample space of both events

$B = \{6\}$

$E = \{2,4,6\}$

Calculating the size of |E n B|

$|E n B| = \{2,4,6\}\ n\ \{6\}$

$|E n B| = \{2,4,6\}$

The size = 3 because it contains 3 possible outcomes

Calculating the size of |B|

$B = \{6\}$

The size = 1 because it contains 1 possible outcome

(06.01) What is the value of the expression shown below? 3 over 6 to the power of 2 + 7 × 4 − 5 6 and 1 over 4 6 and 1 over 2 23

never [62]

Answer: 23(1/4)

Step-by-step explanation: this is the answer you can star resolving the equation into the parenthesis

(3/6)² + 7 *4 - 5

if we elevate to the power of 2 the values into the parenthesis, we get the following equation.

(9/36) + 7*4 -5

after this we follow with the values into the parenthesis, if you divide 9 over 36 we get the following result

9/36 = 0.25

then we get the following equation

0.25 +7*4 - 5

after that we can resolve the multiplication getting the following equation

0.25 +28 - 5

then if we resolve the subtraction, we will get this result.

28-5 = 23

then we have 0.25 + 23 this equation is equal to 23.25

if you follow the answer will be one with 23, then we get the possible results, if you divide 1/4=0.25

then we get that the result is

23(1/4)
