The probability to the statement to be true is 1/5.

Probability:

Probability refers the chance of an event occurring.

The formula of the probability is,

Probability = the number of ways of achieving success / the total number of possible outcomes.

Given,

The inhabitants of an island tell

the truth with probability 1/3 and

lie with probability 2/3, independently of each other.

One islander makes a statement. a second islander says that the first islander told the truth.

Here we need to find the probability of the statement.

Let us assuming the two islanders statements are independent, the probability they both told the truth is

=> 1/3 x 1/3 = 1/6

If the probability of the second guy backing up the first statement is the probability they both lied or they both told the truth

=> (2/3 x 2/3) + (1/3 x 1/3)

=> 4/9 + 1/6

=> 5/9

So, the probability of the first guy telling the truth, given that the second guy claiming it was true

=> P(A|B) = P(AB)/P(B)

=>  (1/9) / (5/9) = 1/5.

Step-by-step explanation:

The formula for slope is (y2 - y1)/(x2-x1)

In this case, it is (2 - 1/2)/(4-1) which is 1.5 over 3. The slope is 1/2

Step-by-step explanation:

[tex]a_n[/tex] is the n-th term in the sequence. So

• the first term (n = 1) is a₁ = 3 + 6•(1 - 1) = 3

• the second term (n = 2) is a₂ = 3 + 6•(2 - 1) = 9

• the third term (n = 3) is a₃ = 3 + 6•(3 - 1) = 15

• the fourth term (n = 4) is a₄ = 3 + 6•(4 - 1) = 21

• the fifth term (n = 5) is a₅ = 3 + 6•(5 - 1) = 27

The common difference between terms is what you get from subtracting consecutive terms in the sequence, or the number [tex]a_n-a_{n-1}[/tex]. Just by taking any two consecutive numbers from above, you have d = 6, since

9 - 3 = 6

15 - 9 = 6

and so on. More generally,

[tex]a_n-a_{n-1}=(3+6\cdot(n-1)) - (3+6\cdot(n-2))=6\cdot((n-1)-(n-2))=6[/tex]

28 cm³ water entered the tank between 2 and 8 minutes;

Explanation

Rate of flow of water r(t) = dV/dt = 3√(t/2);

Flow of water between 2 and 8 minutes;

[tex]\int\limits dV = \int\limits^8_2 {3\sqrt{t/2} } \, dx[/tex]

[tex]V = 3/\sqrt{2} \int\limits^8_2 {\sqrt{t} } \, dt\\[/tex]

[tex]\\V = 2/\sqrt{2} (8^{3/2}- 2^{3/2} )\\[/tex]

V = 28 cm³

The flow rate of a liquid is how a whole lot fluid passes through a place in a specific time. float fee can be articulated in either in terms of velocity and cross-sectional place, or time and quantity. As liquids are incompressible, the price of circulate an area must be equal to the rate of waft out of an area.

How do I calculate flow rate?

Rate is the flow rate or speed of the water, using the unit “meters per second. “ For example: The object travels a 5 meter length of stream in 8 seconds. Divide 5 (length traveled) by 8 (time it took to travel the distance) for an answer of .

Answer:

2x-3/y-5/37=0

Step-by-step explanation:

here, given equation of line is

y=3/2x+3

or,y(2x+3)=3

or,2x+3=3/y

or,2x-3/y+3=0...eqn(i)

equation of any line parallel to line (i) is

2x-3/y+k=0.. eqn(ii)

since, the line passes through (4,5)[replacing x=4 and y=5 in eqn(ii), we get]

2*4-3/5+k=0

or,8-3/5+k=0

or,40-3/5+k=0

or,k=-5/37

substituting the value of k=-5/37 in eqn(ii)

2x-3/y-5/37=0 is the required equation of line.

Vertical Angles are angles that are opposite of each other and are created by the same lines.

Step-by-step explanation:

the slope is (y coordinate change / x coordinate change) when going from on point on the line to another.

it does not matter in what direction we go, but it is important to keep the same direction for the x and for the y comparison.

so, because I prefer to go from left to right, let's go from

(-16, 8) to (-3, -4) :

x changes by +13 (from -16 to -3).

y changes by -12 (from 8 to -4).

so, the slope is

-12/+13 = -12/13

Step-by-step explanation:

Step-by-step explanation:

let the numbers be x and y

The system of equations is:

x+y=10

x-y=6

By elimination method,we can:

1. Add both equations to eliminate y and simplify

OR

2.Subtract both equations to eliminate x and simplify.

Going by the first approach

x+x+y+(-y)=10+6

2x+0=16

x=16/2=8

Plug x=8 into any equation,say equation 2

x-y=6

8-y=6

8-6=y

y=2
