Answer: The smallest two-digit prime number such that reversing the digits of the number produces a composite number is 19

Step-by-step explanation:

11, which is the smallest two-digit prime number, 11 remains the same number when the digits are reversed, and it is a prime number, of course.

The next two-digit prime number is 13. 13 becomes the prime number 31 when the digits are reversed.

17 is the following two-digit prime number. The result of flipping the digits of 17 is 71, a prime number.

19 is the following two-digit prime number. Reversing the digits of 19 results in 91, which is composite because 7*13= 91

Answer:

65

Step-by-step explanation:

Since 39 is 60%, 100/60= 1 2/3

39*1 2/3 is 65

the probablilty of p and k is 82.6%.

Given:

key club P(k) = 2.3%

physics P(p) = 8.6%

(p∩k) = 1.9%

formula:

P(p/k) = P(p∩k)/P(k)

putting the value,

P(p/k) = 1,9%/2.3%

= 0.019/0.023

= 0.826 = 82.6%

hence the probability of p given k is 82.6%.

The probability of P given K is 0.826.

Given information;

The guidance department has stated that of the senior class, 2.3% are members of key club, K, 8.6% are enrolled in AP physics, P, and 1.9% are enrolled in both. This information is supplied in the question.

To get the probability of P given K [P(A)];

P(K) = 2.3

P(P) = 8.6

P(P ∩ K) = 1.9

P(A) = P(P ∩ K) / P(K)

       = 1.9/2.3

       = 0.826

Hence, the probability of P given K is 0.826.

Point Slope Form:  y - 0=2 (x - 0)

Simplified Form:  y=2x

Step-by-step explanation:

The point-slope form of line is given by:

y - y1=m(x - x1)

Where

m is the slope

 is the first x-coordinate

 is the first y-coordinate

Given slope is 2, thus we can say:

m = 2

Also, it says the line goes through the point (0,0), so:

and

Now, substituting, we get the point slope form to be:

y-y1=m(x - x1)

y-0=2(r-0)

y=2(x)

y=2x

The equation of line will be y = 2x

The slope of the equation m = 2 and the point P ( x₁ , y₁ ) = P ( 0 , 0 )

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be represented as A

Let the point be represented as P

The value of P = P ( 0 , 0 )

The slope of the equation m = 2

Slope m = 2

Now , the equation of line in the slope intercept form is

y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 0 = 2 ( x - 0 )

On simplifying the equation , we get

y = 2x

Therefore , the value of A is y = 2x

Hence , the equation of line is y = 2x

First, let us understand the equation:

An equation is a mathematical expression that includes the equals sign. Algebra is frequently used in equations.

We are given;

x / (x + 8) + 1 / (x - 8) = 2x / (x^2 - 64)

x (x - 8) + 1 (x + 8) / (x^2 - 64) = 2x / (x^2 - 64)

x^2 - 8x + x + 8 = 2x

x^2 - 8x - 2x + x + 8 = 0

x^2 - 9x + 8 = 0

x^2 - 8x - x + 8 = 0

x(x - 8) - 1 (x - 8) = 0

(x - 1) (x - 8) = 0

(x - 1) = 0 or (x - 8) = 0

x = 1 or x = 8

The coordinates of the endpoint A = (A, B) is (60, 9)

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

Midpoint = (31, -5) = (x, y)

Endpoints:

A = (a, b) and B = (2, -19) = (c, d)

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Now,

31 = (a + 2)/2

31 x 2 = a + 2

62 = a + 2

a = 62 - 2

a = 60

-5 = (b - 19)/2

-5 x 2 = b - 19
