A biologist estimates that there are 1,800 fish in a quarry. To test this estimate, a student caught 150 fish from the quarry, tagged them, and released them. A few days later, the student caught 50 fish and noted that 4 were tagged. Determine whether the biologist's estimate is likely to be accurate.​

Answer:

3.6

Step-by-step explanation:

To find the distance of two points you use the formula [tex]\sqrt{x2-x1)^{2} +(y2-y1)^{2} }[/tex]

so all we have to do is plug in the x's and y's

the points given are (-8,6) and (-5,8) so  we would do

[tex]\sqrt{(-5-(-8))^{2} +(8-6)^{2} }[/tex]

if you plug that into a calculator you get that the distance between the two points are 3.605551275

but you would just want to round to the nearest tenth so the distance between the two points are 3.6

hope this helps and if you have nay questions lmk :D

Answer:

1/2

Step-by-step explanation:

3/4 * 2/3 = 1/2

Divisibility rule of 2-last digit divisibility

Divisibility rule of 3-sum of digit divisibility

Divisibility rule of 4-last 2 digits divisibility

Divisibility rule of 5-last digit 0 or 5

Divisibility rule of 6-divisible by both 2 and 3

Divisibility rule of 9-sum of digits divisibility

Divisibility rule of 10-last digit 0

Now we can see that last digit 6 is divisible by 2

2+6+1+6=15 is divisible by 3

16 is divisible by 4

6 is not 0,5 so 2616 is not divisible by 5

2616 divisible by both 2 and 3 so its divisible by 6

2+6+1+6=15 is not divisible by 9

6 is not 0 so 2616 is not divisible by 10

Hope it helped!

Answer:

Answer:

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12

Step-by-step explanation:

Given - Pattern A: start with 12 and add 12

             Pattern B: start with 4 and add 2

To find - Which statement best describes the relationship between the

              corresponding terms of Patter A and Pattern B.

Proof -

To find the relationship between the Pattern a and pattern B , firstly we have to find few terms of both the Patterns , so that we can see how the digits of both the Patterns are realted

Now,

For Pattern A :

1st digit = 12

2nd digit = 12 + 12 = 24

3rd digit = 24 + 12 = 36

4th term = 36 + 12 = 48

5th term = 48 + 12 = 60

.

.

.

and so on

Now,

For Pattern B :

1st digit = 4

2nd digit = 4 + 2 = 6

3rd digit = 6 + 2 = 8

4th term = 8 + 2 = 10

5th term = 10 + 2 = 12

∴ we get

Terms of Pattern A : 12, 24, 36, 48, 60, ....

Terms of Pattern B :  4, 6, 8, 10, 12, ....

As we can see that

4×6 - 12 = 12

6×6 - 12 = 24

8×6 - 12 = 36

10×6 - 12 = 48

12×6 - 12 = 60

.

.

The pattern is - Multiply by 6 in Pattern B and after that subtract by 12 , we get Pattern A.

Term in Pattern A = 6×corresponding term of Pattern B - 12

i.e. , we get

Each term in Pattern A is equals to 6 times the value of corresponding term in Pattern B and subtract 12

Answer:

-3x-17

Step-by-step explanation:

We need to expand this term by multiplying a term and an expression.

The following product distributive property will be used:

In our example, the resulting expression will consist of 2 terms:

the first term is a product of  and .

the second term is a product of  and .

Answer:

10°

Step-by-step explanation:

180-20 = 160

<BCA = 160°

AC=CB because its Radius

so the angle for <CBA and <BAD also the same

(180 - 160) ÷ 2 = <BAD

<BAD = 10°

Answer:

∠ BAD = 10°

Step-by-step explanation:

The inscribed angle BAD is half the measure of the central angle BCD, then

∠ BAD = [tex]\frac{1}{2}[/tex] × 20° = 10°

Answer:

the answer would be anything 11 and under (11,10,9,8,7,6,5,4,3,2,1,0)

Step-by-step explanation:

This is because if n+5 is less than or equal to 16 then 11+5=16 so that is equal to and less than would be using any number less than 11

hope this helps ;)

Answer:

n ≤ 11

Step-by-step explanation:

n+5≤16

 -5  -5

n≤11 after subtracting 5 from both sides

Answer:

A = P(1+rt)

A = $1500(1 + 15*0.043)

A = $2467.5

Answer:

some of interior angles of hexagon = 720°

therefore,

720 = 121 + 96 + 101 + 162 + 90 + x

720 = 570 + x

729 - 570 = x

150 = x

Answer: 4x + 8 = 12

Step-by-step explanation: U combine 3x + 4x - 3x = 4x and just add 8 add 12 to the equation

Answer:

A) = 4.

B) = 25.

C) = 4.

Step-by-step explanation:

We are given that a and b are positive integers and that:

[tex]a-b=2[/tex]

And we want to evaluate the following expressions.

Expression A)

We have:

[tex]\displaystyle \frac{2^a}{2^b}[/tex]

This is equivalent to:

[tex]=2^a\div 2^b[/tex]

Therefore:

[tex]=2^{a-b}[/tex]

Substitute and evaluate:

[tex]=2^{(2)}=4[/tex]

Expression B)

We have:

[tex]\displaystyle \frac{5^a}{5^b}[/tex]

This is equivalent to:

[tex]=5^{a-b}[/tex]

Again, substitute and evaluate:

[tex]=5^{(2)}=25[/tex]

Expression C)

Lastly, we have:

[tex]\displaystyle \frac{4^{0.5a}}{2^b}[/tex]

Note that 4 = 2². Hence:

[tex]=\displaystyle \frac{(2)^{2(0.5a)}}{2^b}[/tex]

Simplify:

[tex]=\displaystyle \frac{2^a}{2^b}[/tex]

Using the previous result:

[tex]=4[/tex]

Answer:

x=20

Step-by-step explanation:

so we just mark ADB as 45 and BDC as 50 and now we can find B and C by doing 180-50=130/2 so B=65 and C=65 now we have 2 angles so we can find x. D is 95 bc we add 45 and 50 and C is 65 like i wrote there so we add 95+65 and get 160 and we subtract 160 from 180 to get x=20
