Step-by-step explanation:

The needed inequality is (6 X)   > (12 Y) .6 hens x 200 eggs per year = 1,200 eggs per year, or 23+ eggs per week.

According to the given data:

The number of eggs laid by first hen per week = 6 eggs

So, the number of eggs laid by first hen in X weeks

= (Eggs Laid per week) x  (X)   = 6 X

So, the first hen lays a total of (6 X) eggs in X weeks.

Similarly,

The number of eggs laid by second hen per week =  9 eggs

So, the number of eggs laid by second hen in Y weeks

= (Eggs Laid per week) x  (Y)   = 9 Y

So, the second hen lays a total of (9 Y) eggs in Y weeks.

As given:

The total number of eggs laid by the first hen >  The total number of eggs laid by the second hen.

⇒ (6 X)   > (9 Y)  

Hence, the needed inequality is (6 X)   > (9 Y) .

Taking into account the rule of three, the manager will order 12 small shirts ans 18 large shirts for every 24 medium shirts.

The rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

That is, what is intended with it is to find the fourth term of a proportion knowing the other three.  

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.

To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:

a ⇒ b

c ⇒ x

So: x= (c×b)÷a

In this case, you can applied the rule of three as follow:

amount of small shirts= (24 medium shirts× 2 small shirts)÷4 medium shirts

amount of small shirts= 12

amount of large shirts= (24 medium shirts× 3 large shirts)÷4 medium shirts

amount of large shirts= 18

In summary, the manager will order 12 small shirts ans 18 large shirts for every 24 medium shirts.

We divide both sides by 8, which yields -2 = x. This means that x is equal to -2, the correct answer is B) x = -2.

To solve the equation -9x + 1 = -x + 17, we can simplify and isolate the variable x.

First, let's combine like terms by adding 9x to both sides:

-9x + 9x + 1 = -x + 9x + 17

Simplifying further:

1 = 8x + 17

Next, let's isolate the variable x by subtracting 17 from both sides:

1 - 17 = 8x + 17 - 17

Simplifying again:

-16 = 8x

To solve for x, we divide both sides by 8:

-16/8 = 8x/8

-2 = x

Therefore, the solution to the equation -9x + 1 = -x + 17 is x = -2.

To solve the equation, we want to isolate the variable x on one side of the equation. We start by combining like terms. By adding 9x to both sides, we eliminate the variable terms on the left side, resulting in 1 = 8x + 17.

Next, we isolate the variable x by subtracting 17 from both sides. This simplifies the equation to -16 = 8x.

To solve for x, we divide both sides by 8, which yields -2 = x. This means that x is equal to -2. Therefore, the correct answer is B) x = -2.

The (d^2 y / dt^2) (0) = -28/125.

The ordinary differential equation given is dy/dt = (4 - 4y) / (5 + 3y) with the initial condition y(0) = 0. To find (d^2 y / dt^2) (0), we need to find the second derivative of y with respect to t at t = 0.

First, let's find the first derivative of y with respect to t at t = 0. Using the initial condition y(0) = 0, we can plug in t = 0 into the equation to find dy/dt at t = 0:

dy/dt = (4 - 4y) / (5 + 3y)

dy/dt = (4 - 4(0)) / (5 + 3(0))

dy/dt = 4/5

So the first derivative of y with respect to t at t = 0 is 4/5.

Next, we need to find the second derivative of y with respect to t at t = 0. To do this, we can take the derivative of the first derivative with respect to t:

d^2 y / dt^2 = d/dt (dy/dt)

d^2 y / dt^2 = d/dt (4 - 4y) / (5 + 3y)

Using the quotient rule, we can find the derivative of the right hand side of the equation:

d^2 y / dt^2 = [(5 + 3y)(-4dy/dt) - (4 - 4y)(3dy/dt)] / (5 + 3y)^2

Now we can plug in t = 0 and dy/dt = 4/5 into the equation to find the second derivative at t = 0:

d^2 y / dt^2 = [(5 + 3(0))(-4(4/5)) - (4 - 4(0))(3(4/5))] / (5 + 3(0))^2

d^2 y / dt^2 = (-16/5 - 12/5) / 25

d^2 y / dt^2 = -28/125

So the second derivative of y with respect to t at t = 0 is -28/125.

Therefore, (d^2 y / dt^2) (0) = -28/125.

Approximation of y(0.5) using RK4: 0.5714 (4 decimal places).

To approximate the value of y(0.5) using the fourth-order Runge-Kutta (RK4) method with a step size of h = 0.1 and the initial condition y(0) = 0.6, we perform iterative calculations.

Starting with x = 0 and y = 0.6, we calculate k1, k2, k3, and k4 using the given differential equation y' = (x - y).

Then, we update x and y using a weighted average of these values. Repeating these steps until x reaches 0.5, we obtain the approximate value of y(0.5) as 0.5714 (rounded to four decimal places), which matches the given value. The RK4 method provides a reliable numerical approximation for solving differential equations.

3 is the minimum number of guesses required to guarantee that you know the number.

If we use a binary search approach, we can guess the number in a minimum number of steps.

First, we guess the middle number, which is 8. If the answer is higher, we can eliminate all the numbers from 1 to 8, because they are lower than the answer.

Then we guess the middle number of the remaining numbers, which is 12. If the answer is lower, we can eliminate all the numbers from 12 to 15, because they are higher than the answer.

We have now eliminated half of the remaining numbers, and we are left with 6 and 7. We can guess either of these numbers, and we will know the answer with a total of three guesses.

The cardinality of the cartesian product of A and B is 18.

Cartesian Product of two sets A and B is defined as the set of all ordered pairs (a,b) where a∈A & b∈B.

Cardinality of a set is defined as the number of elements in that particular set.

For example,  for a set A={2,6,4} , the cardinality is 3.

Given set A= { x | x is a prime number less than 7}

A={2,3,5}

set B =  { y | y is perfect square of an integer and y is less than 29}

B={0,1,4,9,16,25}

The cartesian product of A and B denoted by AxB will be

AxB={(2,0),(2,1),(2,4),(2,9),(2,16),(2,25),(3,0),(3,1),(3,4),(3,9),(3,16),(3,25),(5,0),(5,1),(5,4),(5,9),(5,16),(5,25)}

The student has incorrectly added 8 on both sides of the equation instead of subtracting it.

The general form of an equation is given as,

(y ₋ y₁)=m(x ₋ x₁)

where (x₁,y₁) is the point through which the line passes and m is the slope of the line.

Given that a line has a slope of -6 and passes through the point (2, –8). Therefore, substitute the slope and point in the above general form of the line and simplify.

(y ₋ y₁)=m(x ₋ x₁)

[y ₋ (-8)] = (-6)(x ₋ 2)

y + 8 = -6x + 12

Subtract 8 from both sides of the equation,

y + 8 - 8 = -6x + 12 - 8

y = -6x + 4

Now, if the steps are compared it can be seen that parenthesis are not opened properly and instead of subtracting 8, it is added to both sides of the equation.

Hence, the student has incorrectly added 8 on both sides of the equation.

To find the approximate measurements of the angles of triangle PQR, we can use the dot product formula and the Law of Cosines.

First, let's find the vectors PQ and PR:

Vector PQ = Q - P = (3, 3, 1) - (0, -1, 5) = (3, 4, -4)

Vector PR = R - P = (-4, 4, 6) - (0, -1, 5) = (-4, 5, 1)

Next, we'll find the lengths of vectors PQ and PR:

|PQ| = sqrt((3)^2 + (4)^2 + (-4)^2) = sqrt(9 + 16 + 16) = sqrt(41)

|PR| = sqrt((-4)^2 + (5)^2 + (1)^2) = sqrt(16 + 25 + 1) = sqrt(42)

Now, we can find the dot product of vectors PQ and PR:

PQ · PR = (3)(-4) + (4)(5) + (-4)(1) = -12 + 20 - 4 = 4

Using the dot product and the lengths of PQ and PR, we can calculate the cosine of each angle using the Law of Cosines:

cos(angle P) = (PQ · PR) / (|PQ| |PR|)

cos(angle Q) = (QR · QP) / (|QR| |QP|)

cos(angle R) = (RP · RQ) / (|RP| |RQ|)

Substituting the values:

cos(angle P) = 4 / (sqrt(41) sqrt(42))

cos(angle Q) = -4 / (sqrt(41) sqrt(42))

cos(angle R) = 8 / (sqrt(42) sqrt(41))

Finally, we can calculate the approximate measurements of the angles using the inverse cosine function:

angle P ≈ arccos(cos(angle P))

angle Q ≈ arccos(cos(angle Q))

angle R ≈ arccos(cos(angle R))

Note: The angles will be in radians. To convert to degrees, you can multiply by (180 / π).
