Answer:

3.3h-3.1d-17

Step-by-step explanation:

A linear pair of angles cannot add up to anything other than 180 degrees.

They cannot be complementary because complementary means add up to 90 degrees.

The required value of x for the given condition g(x) = f(2) is x = 2.

This relationship is regularly represented as y = f(x) — which is expressed "f of x" — and y and x are connected with the end goal that for each x, there is an extraordinary worth of y. That is, f(x) can not have more than one incentive for a similar x. To utilize the language of set hypothesis, a capability relates a component x to a component f(x) in one more set.

f(x) = 3x - 1 and g(x) = 2x - 3

To find value of x for g(x) = f(2)

Then, f(2) = 3(2) - 1 = 6 - 1 = 5

So, g(x) = 2x - 3 = 5

2x = 8

x = 4

Thus at x = 4   g(x) = f(2).

Answer:

3.25

Step-by-step explanation:

μX = 2(0.3) + 3(0.2) + 4(0.4) + 5(0.1) = 3.3

The mean of the distribution represented by the histogram is 3.25

The mean is the product of the value of X and its corresponding probability (P(x)).

The mean can be expressed thus :

From the histogram :

Mean = (1 × 0.05) + (2 × 0.2) + (3 × 0.35) + (4 × 0.25) + (5 × 0.15)

Mean = 0.05 + 0.40 + 1.05 + 1.00 + 0.75 = 3.25

The friend is referring to an empirical probability.

Empirical probability is based on observed data or outcomes from experiments or real-world events. In this case, the friend is flipping a coin multiple times and making an observation about the probability of getting a head based on the outcomes they have observed.

Theoretical probability, on the other hand, is based on mathematical calculations and assumptions. It involves using mathematical models or formulas to determine the probability of an event occurring. Theoretical probabilities are derived from mathematical principles and do not rely on observed data or experiments.

In the given scenario, the friend's statement that the probability of getting a head is e because he got heads is based on the observed data from the coin flips. The friend is using the observed outcomes to estimate the probability of getting a head. This estimation is a result of empirical probability, which is based on observations and experiments rather than theoretical calculations.

The algebraic expression for the given phrase would be: c + 6, where c represents the unknown quantity (number of cars in the garage) and 6 represents the number of cars outside.

To translate the following phrase into an algebraic expression, we need to use the variable c to represent the unknown quantity. The phrase is "the total of the number of cars in the garage and the 6 cars outside."

So, the algebraic expression is: c + 6Where "c" represents the number of cars in the garage.

The expression c + 6 represents the total number of cars, which is the sum of the number of cars in the garage and the 6 cars outside.

Example: If there are 10 cars in the garage, then the total number of cars would be: c + 6= 10 + 6= 16.

So, there would be 16 cars in total.

The expression c + 6 would always give us the total number of cars, regardless of the value of "c."

Therefore, the volume of the solid bounded by the coordinate planes and the plane 6x + 4y + z = 24 is 96 cubic units.

To find the volume of the solid bounded by the coordinate planes (xy-plane, xz-plane, and yz-plane) and the plane 6x + 4y + z = 24, we need to determine the region in space enclosed by these boundaries.

First, let's consider the plane equation 6x + 4y + z = 24. To find the x-intercept, we set y = 0 and z = 0:

6x + 4(0) + 0 = 24

6x = 24

x = 4

So, the plane intersects the x-axis at (4, 0, 0).

Similarly, to find the y-intercept, we set x = 0 and z = 0:

6(0) + 4y + 0 = 24

4y = 24

y = 6

So, the plane intersects the y-axis at (0, 6, 0).

To find the z-intercept, we set x = 0 and y = 0:

6(0) + 4(0) + z = 24

z = 24

So, the plane intersects the z-axis at (0, 0, 24).

We can visualize that the solid bounded by the coordinate planes and the plane 6x + 4y + z = 24 is a tetrahedron with vertices at (4, 0, 0), (0, 6, 0), (0, 0, 24), and the origin (0, 0, 0).

To find the volume of this tetrahedron, we can use the formula:

Volume = (1/3) * base area * height

The base of the tetrahedron is a right triangle with sides of length 4 and 6. The area of this triangle is (1/2) * base * height = (1/2) * 4 * 6 = 12.

The height of the tetrahedron is the z-coordinate of the vertex (0, 0, 24), which is 24.

Plugging these values into the volume formula:

Volume = (1/3) * 12 * 24

= 96 cubic units

The thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.

From the question we know that :

n = 1.30

λ = 500nm = 5 x 10¯⁷m

The non-reflective coating system is applied on glass and the refractive index of that system should be  nair < ncoating < nglass. The light travels across the air and is refracted by coating film and then refracted again by the glass. For preventing the light got reflected by glass, the thickness of the layer should obey this equation :

2nt = λ/2

t is the thickness of the layer, λ is the wavelength and n is the refractive index of the film.

By substituting the following equation we get

2nt = λ/2

t = 1/4 . ( λ / n )

t = 1/4 . ( 5 x 10¯⁷ / 1.3)

t = 9.62 x 10¯⁸ m

Hence, the thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.

The expression for the area under the graph of f(x) over the interval [2, 4] is given by the limit as n approaches infinity of the Riemann sum: A = lim(n→∞) Σ[f(xi)Δx].

To express the area under the graph of f(x) as a limit, we divide the interval [2, 4] into n subintervals of equal width Δx = (4 - 2)/n = 2/n.

Let xi be the right endpoint of each subinterval, with i ranging from 1 to n. The area of each rectangle is given by f(xi)Δx.

By summing the areas of all the rectangles, we obtain the Riemann sum: A = Σ[f(xi)Δx], where the summation is taken from i = 1 to n.

To find the expression for the area under the graph of f(x) as a limit, we let n approach infinity, making the width of the rectangles infinitely small.

This leads to the definite integral: A = ∫[2, 4] f(x) dx.

In this case, the expression for the area under the graph of f(x) over the interval [2, 4] is given by the limit as n approaches infinity of the Riemann sum: A = lim(n→∞) Σ[f(xi)Δx].

Evaluating this limit would yield the actual value of the area under the curve.

Answer:

In 5 weeks, Ayana and Michelle have the same amount of money saved

(Namely $75)

Step-by-step explanation:

Ayana has $200 and spends $25 per week.

Michelle has $0 and saves $15 per week.

So, after one week,

Ayana has $200 - $25 = $175

Michelle has $0 + $ 15 = $15

After 2 weeks,

Ayana has $175 - $25 = $150

Michelle has $15 + $15 = $30

After 4 weeks,

Ayana has $150 - $50 = $100

Michelle has $30 + $30 = $60

After 5 weeks,

Ayana has $100 - $25 = $75

Michelle has $60 + $15 = $75

So, in 5 weeks, Ayana and Michelle have the same amount of money saved

Ayana and Michelle will have the same amount of money saved in 5 weeks.

To calculate the number of weeks Ayana and Michelle will take to have the same ammount of money, we have to make use of assumption. The reason for this is, as the number of weeks are yet to be found, so the value can only be found by substituting that particular entity into a variable.

Let's assume that number of weeks Ayana and Michelle will take to have the same ammount of money is "x".

So, Amount saved by Ayana after x weeks will be $200 - $25*x,

Amount saved by Michelle in x weeks will be $15 * x.

In the question, we have been told that Ayana and Michelle have the same amount of money saved, So we need to equate to above two equations to find the value of "x".

$200 - $25*x = $15 * x

$200 = $15 * x + $25*x

$200 = $40*x

$200 / $40 = x

x = 5

Therefore, Ayana and Michelle will take 5 weeks to have the same amound of money saved.
