The solution to the system of equations is

The number of ducks D = 8 ducks

The number of cows C = 6 cows

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of ducks be D

Let the number of cows be C

Now , the total number of animals = 14

So , D + C = 14   be equation (1)

And , the total number of legs = 40

Number of legs for ducks = 2 legs

Number of legs for cows = 4 legs

And , the total number of legs = 2D + 4C = 40

So , 2D + 4C = 40   be equation (2)

On simplifying the equations , we get

Multiply equation (1) by 2 , we get

2D + 2C = 28   be equation (3)

Subtracting equation (3) from equation (2) , we get

2C = 40 - 28

2C = 12

Divide by 12 on both sides of the equation , we get

C = 6 cows

Substituting the value of C in equation (1) , we get

D = 14 - 6

D = 8 ducks

Therefore , the value of C and D is 6 and 8 respectively

Hence , the number of cows is 6 and number of ducks is 8

The probability that the student finishes the inquiry in less than 1.5 hours is 0.45.

Mean= 4/3 and standard deviation= √(11/90)

a) To find the probability that the student finishes the inquiry in less than 1.5 hours, we need to find the area under the probability density function (PDF) of f(x) between the lower limit of 1 and the upper limit of 1.5.

This is given by the definite integral of f(x) from 1 to 1.5:

∫f(x)dx from 1 to 1.5

= ∫(2/5(x + 1))dx from 1 to 1.5

= (2/5)∫(x + 1)dx from 1 to 1.5

= (2/5)[x^2/2 + x] from 1 to 1.5

= (2/5)[(1.5)^2/2 + 1.5 - (1)^2/2 - 1]

= (2/5)[2.25/2 + 1.5 - 1/2 - 1]

=(2/5)[2.25/2]

=0.45

b) To find the mean, we need to use the formula:

Mean = ∫x*f(x)dx from a to b

In this case:

Mean = ∫x*(2/5(x + 1))dx from 1 to 2

= (2/5)∫x(x + 1)dx from 1 to 2

= (2/5)[x^3/3 + x^2/2] from 1 to 2

=(2/5)[(2)^3/3 + (2)^2/2 - (1)^3/3 - (1)^2/2]

= (2/5)[8/3 + 4/2 - 1/3 - 1/2]

=(2/5)[7/3 + 3/2]

=(2/5)[(20)/6]

=4/3

=1.333

To find the standard deviation, we need to use the formula:

Standard deviation^2 =(∫(x-μ)^2*f(x)dx) from a to b

Where μ is the mean

In this case,

Standard Deviation ^2= ∫(x-μ)^2(2/5)(x+1) dx from 1 to 2

=(2/5)∫(x-μ)^2(x+1) dx from 1 to 2

Simplifying, we get,

(x-μ)^3*(3x+μ+4)/30 from 1 to 2

=[(2-μ)^3*(6+μ+4)-(1-μ)^3*(3+μ+4)]/30

=[(2-μ)^3*(10+μ)-(1-μ)^3*(7+μ)]/30

Substituting the value of μ,

=[(2-4/3)^3*(10+4/3)-(1-4/3)^3*(7+4/3)]/30

=11/90

Therefore, Standard Deviation= √(11/90)

What is the Arrhenius Equation?

The Arrhenius equation is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction and the temperature (T) of the reaction. The equation was first proposed by Svante Arrhenius in 1889 and it states that the rate constant of a chemical reaction is directly proportional to the exponential of the negative activation energy (Ea) of the reaction, divided by the gas constant (R) and the absolute temperature (T). The equation can be written as:

K = A * e^(-Ea / (R*T))

The Arrhenius Equation Two-point form is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction, the activation energy (Ea) of the reaction, the universal gas constant (R), and the temperature (T) of the reaction.

Given the equation K2/K1 = Ea / R (1/T1 - 1/T2)

a. To solve for K2, we can multiply both sides of the equation by

K1: K2 = K1 * Ea / R (1/T1 - 1/T2)

b. To solve for K1, we can divide both sides of the equation by

Ea / R (1/T1 - 1/T2): K1 = K2 / Ea / R (1/T1 - 1/T2)

c. To solve for Ea, we can multiply both sides of the equation by

R (1/T1 - 1/T2): Ea = K2/K1 * R (1/T1 - 1/T2)

d. To solve for T2, we can use the equation 1/T2= 1/T1 - Ea/R * K1/K2

It's worth noting that to solve for T2 you need to have the values of other variables such as K1, K2, Ea, R and T1.

6x - 7y + 7y = 18 + 7y

6x = 18 + 7y

Next, divide both sides of the equation by 7:

6x/7 = 18/7 + 7y/7

x = 3 + y

So the solution is y = 3 - x
