Temperature is a measure of the average kinetic energy of molecules

Potential Energy is a measure of how much energy can be turned into kinetic energy (think a ball about to be dropped)

Matter is a term for stuff, everything is made of matter, atoms and molecules

Kinetic energy is energy in motion (think a falling object)

States are the position or form things are in, this is probably going to be used as "states of matter" (solids, liquids, gasses)

Conduction is the transfer of heat or electricity through two objects touching

Energy is "the ability to do work" think of energy like a general term for potential and kinetic energy, undefined if you ill

How about this answer to both?  I've seen cylindrical-conic tanks in a local brewery.  The tank is a cone with a cylinder on top.  It's important to know the volumes of both the cylinder and the cone.

Answer:

x = 3

Step-by-step explanation:

First you want to divide both sides by 5 to get 2x-4 = 2.

Afterwards, you add 4 to both sides of the equation. 2x = 6

Divide both sides by 2. x = 3

The value of x = 3 is correct. Therefore, the solution is x = 3.

To solve for x in the equation 5(2x - 4) = 10, follow these steps:

Step 1: Distribute the 5 on the left side of the equation:

10x - 20 = 10

Step 2: Add 20 to both sides to isolate the term with x:

10x - 20 + 20 = 10 + 20

10x = 30

Step 3: Divide both sides by 10 to find the value of x:

x = 30 / 10

x = 3

The solution to the equation is x = 3. To verify, substitute x with 3 in the original equation:

5(2(3) - 4) = 10

5(6 - 4) = 10

5(2) = 10

10 = 10

Since both sides are equal, the value of x = 3 is correct. Therefore, the solution is x = 3.

Greetings from Brasil...

Let M be the age of Mario and L the age of Luigi. According to the statement we can elaborate the following equations:

M = L + 12

(M + 6) + (L + 6) = 32

As M = L + 12, we will substitute in the second equation

(M + 6) + (L + 6) = 32

((L + 12) + 6) + (L + 6) = 32

2L + 24 = 32

2L = 32 - 24

2L = 8

L = 8/2

for M:

M = L + 12

M = 4 + 12

\(Pr = 0.20\)

Step-by-step explanation:

Given

\(n_1 = 10\) ---- 10 sided

\(n_2 = 6\) --- 6 sided

Required

\(P(x_1,x_2 > 4)\)

First, list out the sample space

\(S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)\)

\((3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)\)

\((5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6) (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)\)

\((7, 1) (7, 2) (7, 3) (7, 4) (7, 5) (7, 6) (8, 1) (8, 2) (8, 3) (8, 4) (8, 5) (8, 6)\)

\((9, 1) (9, 2) (9, 3) (9, 4) (9, 5) (9, 6) (10, 1) (10, 2) (10, 3) (10, 4) (10, 5) (10, 6)\}\)

\(n(S) = 60\) --- total outcomes

The event that the outcome of both is greater than 4 is:

\(x_1,x_2> 4 = \{(5, 5) (5, 6)(6, 5) (6, 6)(7, 5) (7, 6) (8, 5) (8, 6)(9, 5) (9, 6) (10, 5) (10, 6)\}\)

\(n(x_1,x_2>4) = 12\)

So, the probability is:

\(Pr = \frac{n(x_1,x_2>4)}{n(S)}\)

\(Pr = \frac{12}{60}\)

\(Pr = 0.20\)

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

One possible system is

1x + 3y = 4

2x + 6y = 8

Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.

In other words, the second equation is the result of multiplying both sides of the first equation by 2.

1x+3y = 4

2*(1x+3y) = 2*4

2x+6y = 8

The correct statement is: 'A one-variable data table has input values that are listed either down a column (column-oriented) or across a row (row-oriented). '

The correct answer is an option (a)

We know that a one-variable data table contain its input values either in a single column (column-oriented), or across a row (row-oriented).

And any formula in this data table must refer to only one input cell.

Whereas we se a two-variable data table to see how different values of two variables in one formula will change the formula results.

The given equation in polar coordinates is r = 18, where 0 ≤ θ ≤ 2π represents a full circle. Answer :  162π

To find the area bounded by the curve, we need to integrate the function r^2/2 with respect to θ over the specified sector.

The area A can be calculated using the formula:

A = ∫[θ_1, θ_2] (1/2) r^2 dθ

In this case, θ_1 = 0 and θ_2 = 2π. Substituting the value of r = 18 into the formula, we get:

A = ∫[0, 2π] (1/2) (18^2) dθ

  = ∫[0, 2π] (1/2) (324) dθ

  = 162π

Hence, the area of the region bounded by the curve r = 18 and lying in the specified sector is 162π square units.

Based on the information you provided, it seems that a simple linear regression model was used to analyze the relationship between the size of a house (in square feet) and its selling price (in 1,000 dollars).

The dependent variable in this model was the price, while the independent variable was the size. The sample size used for this analysis was 8.

The correlation coefficient (r) measures the strength and direction of the linear relationship between two variables. In this case, the correlation coefficient would indicate how closely the selling price of a house is related to its size. The value of r can range from -1 to 1, with values closer to -1 or 1 indicating a stronger relationship, while values closer to 0 indicate a weaker relationship.

Without knowing the specific value of r, it is difficult to draw conclusions about the strength of the relationship between the size of a house and its selling price. However, in general, it is reasonable to assume that there is a positive correlation between these two variables - that is, as the size of a house increases, its selling price is likely to increase as well.

Step-by-step explanation:

The total number of bikes that can be painted in an hour would be 60 bikes.

With three identical machines,

the number of bikes machine can paint per hour = 20,

the number of machines bought again = 2,

so the total number of machines will be = 3,

when there are two same machines the productivity will be = 20 * 3 = 60 bikes.

This is because each machine works independently and can paint bikes simultaneously.

By adding two additional machines to the existing one,

the productivity of the painting process can be significantly increased. The new machines will not only increase the overall capacity but also reduce the turnaround time required for painting a large number of bikes.

By investing in additional machines,

the business can increase its output and generate more revenue,

which can be used to expand the operations further.

It's important to note that the investment in additional machines needs to be justified by the demand for painted bikes and the expected return on investment.

Answer: m> 49/12

Step-by-step explanation:

The graph is a parabola . The Parabola with minimum point. So, Substitute the minimum value in the equation. Thus the graph of have two x-intercepts when.

The graph is a parabola with the minimum where x= -b/2a = -7/6.

To have 2 x intercepts, the value at the minimum point must be less than 0, i.e.

3(49/36) - 49/6 + m < 0

49/12 - 49/6 + m < 0

(49-98)/12 + m < 0

-49/12 + m < 0

m < 49/12

The values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.

Any equation of the form \(\rm ax^2+bx+c=0\)  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

\(\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}\)

It is given that:

The equation of the graph:

y = 3x² + 7x + m

If the above quadratic function has two x-intercepts that means:

D > 0

b² - 4ac > 0

On comparing:

a = 3

b = 7

c = m

7² - 4(3)(m) > 0

49 - 12m > 0

12m < 49

m < 49/12

Or

m ∈ (-∞, 49/12) for which graph of a function have two x-intercepts

Thus, the values of m < 49/12 the equation of the function y = 3x² + 7x + m have two x-intercepts option (C) m < 49/12 is correct.
