For the given experiment, the sample space has 6 elements which are:
{10, 12, 14, 16, 18, 20}
How to identify the sample space?
For any experiment with different outputs (each output with a defined probability).
We define the sample space as the set of all the possible outcomes of the experiment.
Now, the experiment here is:
"randomly choosing a number from the even number between 10 and 20 inclusive"
So the possible outcomes are all the even numbers on the interval [10, 20]
Then the sample space of the experiment is:
{10, 12, 14, 16, 18, 20}
It has 6 elements.

graph the line that represents a proportional relationship between y and x where the unit rate of change of y with respect to c is 4/5. in other words a change of 1 unit in x corresponds to a change of 4/5 units in y
The graph that represents the proportional relationship between x and y with a unit rate of 4/5 is shown in the image below.
How to Graph the Line of a Proportional Relationship?If the relationship between x and y is a proportional relationship, the equation that models the relationship between x and y can be expressed as y = mx. Here, the unit rate is represented by the value of in the equation.
This means that, the graph that represents the proportional relationship between x and y would have a slope of the value of m. m, which is the slope of the line, is the ratio of the rose of the line to the run of the line.
Thus, where m = 4/5, the equation that represents the proportional relationship would be:

A person 1.85 m tall walks towards a lamppost on level ground at a rate of 0.5 m/sec. The lamp on the post is 5 m high. At which rate is the tip of the person's shadow moving toward the lamppost when the person is 4 I from the post? Please enter your answer in decimal format with three decimal places.
Using the Pythagorean Theorem and implicit differentiation, it is found that the tip of the person's shadow is moving toward the post at a rate of 0.393 m/sec when the person is 4 m from the post.
What is the Pythagorean Theorem?The Pythagorean Theorem is a geometry axiom that relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, stating that the hypotenuse squared is the sum of the legs squared, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In the context of this problem, we have that:
The distance d between the person's shadow and the lamp is the hypotenuse of a right triangle.The legs are the person shadow and the lamp.Hence the following relation between these variables is established:
d² = x² + y².
Applying implicit differentiation, the rate of change of the distance is given as follows:
[tex]d\frac{dd}{dt} = x\frac{dx}{dt} + y\frac{dy}{dt}[/tex]
The height remains constant, hence:
[tex]\frac{dy}{dt} = 0[/tex]
The other parameters are given as follows:
y = 5 - 1.85 = 3.15 m (vertical distance).x = 4 m (distance of the person from the post).dx/dt = 0.5 m/s (velocity of the person).Hence the distance at the desired instant is:
d² = 4² + 3.15²
d = sqrt(4² + 3.15²)
d = 5.091 m
The rate of change of the distance is found as follows:
5.091dd/dt = 4 x 0.5
dd/dt = 2/5.091
dd/dt = 0.393 m/sec.

[tex]\begin{gathered} r=6+3\sin (1) \\ r=6.05 \\ \\ r=6+3\sin (\text{ -1)} \\ r=5.94 \end{gathered}[/tex]Since sinθ is not equal to sin(-θ), the pole will be the point of symmetry.
To find the x-intercept, substitute 0 for θ:

Jen purchased the items shown in the table.
Item Cost ($)

In the city she lives in, the sales tax rate is 7.15%. In another city, the sales tax rate is 6.35%. How much more is she spending if she purchases the items in the city where she lives? Round to the nearest cent.
She spends the cost of $0.46 if she purchases the items in the city where she lives.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The given data below as:
Cost of the shirt = $11.99
Cost of the shoes = $35.50
Cost of the belt = $6.75
Cost of the socks = $3.00
Total cost of the items = 11.99 + 35.50 + 6.75 + 3.00
Total cost of the items = $57.24
In the city she lives in, the sales tax rate is 7.15%.
Total cost of the items with tax of 7.15%
= 57.24 × 7.15/100 + 57.24 = 4.092 + 57.24 = $61.33
In another city, the sales tax rate is 6.35%
Total cost of the items with tax of 6.35%
= 57.24 × 6.35/100 + 57.24 = 3.633+ 57.24 = $60.87

2. The hypothetical market for flu shots is depicted in the graph below where market equilibrium quantity is 20 flu shots and market equilibrium price is $20 per shot. Assume that there was an external benefit of $20 per flu shot (value of the flu shot by an individual that accrues to bystanders). What would be the socially optimal quantity of flu shots considering the effect of this external benefit? Answer = ____ flu shots How much of a subsidy per shot would make the market equilibrium outcome be equal to the socially optimal equilibrium? Answer = $____ per flu shot (/2.0 Points)
The socially ideal dose of 40 flu vaccines may be determined by the external beneficial effect. While a $10 subsidy for each flu shot would bring the market equilibrium's result into line with the ideal situation for society.
In order to determine customer interest in and market demands for products that are currently in development, hypothetical scenario marketing uses product surveys and made-up scenarios. Utilizing hypothetical marketing can assist small business owners in allocating resources to product categories where customers have shown a need and desire.
The presented example is a positive externality situation since there is an external social benefit and the market equilibrium quantity is lower than the level of output that would be considered optimal for society because it ignores the external benefit. The subsidy is applied to either produce internalities or address externalities per unit.
At each level, there will be a $20 rightward shift in the marginal social benefit curve. With this external benefit effect in mind, 40 shots of the flu vaccine would be the most beneficial for society. The market equilibrium result would be identical to the socially ideal equilibrium with a $10 subsidy for each flu vaccine.

100 points and brainly for right answer A line includes the points (9,10) and (6,9). What is its equation in point-slope form?
Answer:
y = 1/3x + 7
Step-by-step explanation:
A line includes the points (9,10) and (6,9). What is its equation in point-slope form?
slope = change in rise/change in run
so:
slope = change in y/change in x
you are given two points in (x , y) format, points are: (9,10) and (6,9) [second in each pair are the y values]. Figure change in y and x:
y: 10 - 9 = 1
x: 9 - 6 = 3
so slope =y/x = 1/3
slope intercept form is: y = mx + b where m = slope. Substitute in value previously found for slope:
y = 1/3x + b
Now, you need to find y intercept, or b. Using one of the points given, we will use the first one (9,10), calculate for b:
y = 1/3x + b
10 = 1/3(9) + b
10 = 3 + b
subtract 3 from both sides:
10 - 3 = 3 + b - 3
b = 7
Put this into your equation: y = mx + b
y = 1/3x + 7
