Step-by-step explanation:

Answer:

Hey There!

Let's solve...

We know that the given line is

\(y = 4x + 8 \\ \)

Slope is

\(m_{g} = 4 \\ \)

The answer is perpendicular to m which is the negative reciprocal of m_g

\(m = - \frac{1}{ m_{g} } = - \frac{1}{4} \\ \)

\(y = 2 \\ x = 2(2) = - 1 \\ x = 4 - 1 = 3 \\ x = 3\)

The intersection point is

(3,2)

If we substitute the point into

\(y = mx + c \\ y = - \frac{1}{4}x + c \\ \)

Now let's solve y intercept...

\(2 = - \frac{1}{4}(3) + c \\ \\ c = 2 + \frac{3}{4} \\ \)

\( = \frac{8}{4} + \frac{3}{4} \\ \\ = \frac{8 + 3}{4} = \frac{11}{4} \)

Now the required lines are

\(y = - \frac{1}{4}x + \frac{11}{4} \\ \\ m = - \frac{1}{4} \\ \\ c = \frac{11}{4} \)

The production level that minimizes the average cost per unit is 0.64 units.

To find the production level that minimizes the average cost per unit, we need to first find the average cost function.
The average cost function is given by:
AC(x) = c(x)/x

Substituting c(x) = 5x - 8√x - 2, we get:
AC(x) = (5x - 8√x - 2)/x

To minimize the average cost per unit, we need to find the value of x that minimizes the average cost function.
To do this, we need to take the derivative of the average cost function with respect to x and set it equal to 0:
d/dx AC(x) = (5 - 4/√x)/x^2 = 0

Solving for x, we get:
5 = 4/√x
√x = 4/5
x = (4/5)^2
x = 0.64

Therefore, the production level that minimizes the average cost per unit is 0.64 units.

The angle θ1 located in quadrant IV and sin(θ1) is negative.

The angle θ1 located in quadrant IV and sin(θ1) is negative. When an angle is located in quadrant IV, it means that the angle is between 270 and 360 degrees (or between -90 and 0 degrees).

The sin function is negative in quadrants III and IV. Since θ1 is in quadrant IV, sin(θ1) will be negative. This is because sin is defined as the ratio of the opposite side to the hypotenuse in a right triangle. In quadrant IV, the x-coordinate (adjacent side) is positive and the y-coordinate (opposite side) is negative, so sin is negative.

Therefore, we can conclude that the angle θ1 located in quadrant IV and sin(θ1) is negative.

Therefore, the value of y at t = 0.4 is 5.To find the value of y at t = 0.4, we can use the Euler's method. Here are the steps to solve the given differential equation.

1. Given the differential equation y' + 0.2y = 0, we need to find the value of y at t = 0.4.

2. Start with the initial condition y(0) = 5. This gives us the starting point for our approximation.

3. Let's choose a step size h = 0.2. This means we will approximate the value of y at t = 0.4 using the values of y at t = 0, t = 0.2, and t = 0.4.

4. To approximate y at t = 0.2, we use the formula:
  y(0.2) = y(0) + h * (dy/dt)(0)
         = 5 + 0.2 * [y'(0) + 0.2 * y(0)]

5. Substitute the values into the formula:
  y(0.2) = 5 + 0.2 * [y'(0) + 0.2 * 5]

6. Now, let's find the value of y'(0):
  Given the differential equation, y' + 0.2y = 0, we can rearrange it to find y':
  y' = -0.2y

7. Substitute this value into the formula:
  y(0.2) = 5 + 0.2 * [-0.2 * 5 + 0.2 * 5]

8. Simplify the equation:
  y(0.2) = 5 + 0.2 * [0]
         = 5

9. Now, to find y at t = 0.4, we repeat the process using the values of y at t = 0.2 and t = 0.4:
  y(0.4) = y(0.2) + h * (dy/dt)(0.2)
         = 5 + 0.2 * [y'(0.2) + 0.2 * y(0.2)]

10. Substitute the values into the formula:
   y(0.4) = 5 + 0.2 * [(-0.2 * 5) + 0.2 * 5]

11. Simplify the equation:
   y(0.4) = 5 + 0.2 * [0]
          = 5.

To calculate the standard error (SE) for the percentage of young adults who favor gay marriage, we need to consider the sample size and the proportion of individuals in the sample who favor gay marriage.

The formula for calculating the standard error (SE) of a sample proportion is SE = sqrt((p * (1 - p)) / n), where p is the sample proportion and n is the sample size.

In this case, the sample proportion is given as 73% or 0.73, and the sample size is 321 young adults. Substituting these values into the SE formula, we get SE = sqrt((0.73 * (1 - 0.73)) / 321).

To calculate the SE, we first calculate (0.73 * (1 - 0.73)) to get 0.1979. Dividing this value by the sample size of 321 and taking the square root, we find that the SE for the percentage of young adults who favor gay marriage is approximately 0.0211.

Therefore, the standard error (SE) for the percentage of young adults who favor gay marriage, based on the CBS news poll data, is approximately 0.0211 or 2.11%. The SE provides an estimate of the variability or margin of error associated with the sample proportion.

No Solution.

Since, the x-axis (equation y=0) does not intersect y=-7 at any point. The given pair of equations has no solution

Consider the pair of linear equations in two variables x and y.

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

Here a1, b1, c1, a2, b2, c2 are all real numbers.

Note that, a12 + b12 ≠ 0, a22 + b22 ≠ 0

1. If (a1/a2) ≠ (b1/b2), then there will be a unique solution. If we plot the graph, the lines will intersect. This type of equation is called a consistent pair of linear equations.

2. If (a1/a2) = (b1/b2) = (c1/c2), then there will be infinitely many solutions. The lines will coincide. This type of equation is called a dependent pair of linear equations in two variables

3. If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution. If we plot the graph, the lines will be parallel. This type of equation is called an inconsistent pair of linear equations.

Answer:

options 4 and 6 I believe

a. The sampling method that I would use for the given scenario is stratified random sampling.

b. The sampling method that I would use for the given scenario is systematic sampling.

Stratified random sampling is the most effective way to get accurate results in this situation. The university wants to conduct a mail survey of its alumni to collect information about their current employment status to justify charging a higher tuition rate than other universities. Stratified random sampling divides the population into strata based on certain characteristics.

In this case, strata would be the alumni that have different degrees from the university. The information collected through this method will be more representative of the population than simple random sampling. It ensures that each stratum is represented accurately in the sample. It also minimizes the variability within each stratum. It is an effective way of ensuring that each stratum is properly represented.  

Systematic sampling involves selecting every kth element from a list of the population. In this situation, the Environmental Protection Agency (EPA) wants to inspect a sample of 1000 containers from the 40,000 containers known to be in landfills to determine if leakage from the containers has occurred. As the exact location of the containers is no longer known, systematic sampling can be used.

EPA can select every 40th container from the list of the population, as 40,000/1000 = 40. In this way, they will have a random sample of 1000 containers from the 40,000 containers. This sampling method is less time-consuming and more cost-effective than other sampling methods. It also ensures the sample is representative of the entire population.

Hi!

I am not completely sure what you mean but if you are looking for the slope of a line here is the best way to find it.

Y=Mx+b

it look difficult but really it's quite easy and once you get it it's super memorable. Y will always be Y that doesn't change. The M is the slope of the line (don't let equations confuse you with different letters! the M might be different but it is always the letter next to x) and b is the y intercept (where the line crosses y). All you need to find the slope of a line is 3 points. I see here you have a graph. So what you do is count how much it's moving up each block on the graph. I would say your slope is about 1/3. Y is really easy! just find the point it crosses the y axis(horizontal axis or the one going up and down) for yours it's 0. So your answer is y=1/3x+0

b) $67.20

Step-by-step explanation:

Stefan sells Jin a bicycle for $151 and a helmet for $17.

a) How much did Stefan spend originally?

Total cost for Jin = $151 + $17

= $168

The total cost for Jin is 140% of what Stefan spent originally to buy the bike and helmet.

Hence,

140% of $168 = $235.20

b) How much money did he make by selling the bicycle and helmet to Jin?

This is calculated as:

$235.20 - $168

= $67.20
