18:9 as 1:n where n is a decimal?
Answers
Answer:
18 : 9 is the same thing as 18/9.
So if we want 1 : n = 1/n
(18 / 18) / (9 / 18)
=> 1 / 0.5
=> 1 : 0.5
Therefore, n = 0.5 is the solution of the equation.
Thanks!!
Answer:
n = 0.5
Step-by-step explanation:
To answer this question, we must first figure out the ratio 18:9.
What is 18 compared to 9?
If you said that 18 is double the amount of 9, or that 9 is half of 18, you are correct.
Using this logic, we then need to make the variable 'n' in 1:n half of 1 in decimal form.
So, what is half of 1 in decimal form?
If you said 0.5 OR 0.50, you are correct! And that is your answer !
Hope this helps :)

if f(x) = f(g(x)), where f(−2) = 2, f '(−2) = 2, f '(0) = 2, g(0) = −2, and g'(0) = 3, find f '(0). f '(0) =
Answers
Using the chain rule, Therefore, f'(0) = 2.
Using the chain rule, we can take the derivative of both sides of the equation f(x) = f(g(x)) to obtain :
f'(x) = f'(g(x)) * g'(x)
substitute x = 0, we get:
f'(0) = f'(g(0)) * g'(0)
We are given that g(0) = -2 and g'(0) = 3. Therefore, we need to find g(0) and g'(0) in order to determine f'(0).
To do this, we can use the fact that f(x) = f(g(x)). Substituting x = 0 into this equation, we get:
f(0) = f(g(0))
Since f(-2) = 2, we have:
f(g(0)) = f(-2)
Using the chain rule, we can take the derivative of both sides of the equation f(x) = f(g(x)) with respect to x to obtain:
f'(x) = f'(g(x)) * g'(x)
substitute x = -2, we get:
f'(-2) = f'(g(-2)) * g'(-2)
We are given that f'(-2) = 2 and g'(-2) = 3. Therefore, we can solve for f'(g(-2)):
f'(g(-2)) = f'(-2) / g'(-2) = 2/3
Since f'(x) = f'(g(x)) * g'(x), we can substitute g(0) = -2 and f'(g(-2)) = 2/3 into the equation f'(0) = f'(g(0)) * g'(0) to obtain:
f'(0) = f'(g(0)) * g'(0) = f'(g(-2)) * g'(0) = (2/3) * 3 = 2
Therefore, f'(0) = 2.

Note also the equal sign, what you do to one side of the equation, you will do to the other:
y + 6 = -10(x - 4)
First, distribute -10 to all terms within the parenthesis. Multiply -10 to x and -4. Note that:
1) When you multiply a negative and a positive term together, the answer will be negative.
2) When you multiply two negative terms together, the answer will be positive.
y + 6 = -10(x - 4)
y + 6 = (-10 * x) + (-10 * -4)
y + 6 = -10x + 40
Next, isolate the variable, y. Do so by subtracting 6 from both sides of the equation:
y + 6 (-6) = -10x + 40 (-6)
y = -10x + (40 - 6)
y = -10x + 34
y = -10x + 34 is your answer.

consider an undirected graph that has 100 vertices. for any pair of vertices, only 1 edge can connect them. in other words, you cannot have 2 edges connecting vertex a directly to vertex b. also assume that there are no self-loops, i.e. an edge that goes from vertex a to vertex a. what is the maximum number of edges that can be in this specific graph?
Answers
So the maximum number of edges in an undirected graph with 100 vertices is 4950.
In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.
In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:
n * (n-1) / 2
Substituting n = 100, we get:
100 * 99 / 2 = 4950

Yes, it is True. If we change the constraint quantity to a value outside the range of feasibility for that constraint quantity, the shadow price will change.
The shadow price is the marginal value of the constraint quantity, and it represents the increase in the objective function per unit increase in the constraint quantity. If the constraint quantity is changed to a value outside the range of feasibility, the shadow price will change because the relationship between the objective function and the constraint quantity has changed. The change in shadow price will depend on how the constraint affects the objective function, but it is typically that the shadow price will increase as the constraint becomes more binding.

Answers
The statement that is not a characteristic of the normal probability distribution is "the graph of the curve is the shape of a rectangle."
The normal probability distribution is a continuous probability distribution that is symmetrical and bell-shaped. It is described by its mean and standard deviation, and its graph can be used to represent the distribution of a continuous random variable. The total area under the curve of the normal distribution is equal to 1, which represents the probability of observing any value within the range of the distribution.
The mean, median, and mode of a normal distribution are equal and located at the center of the distribution. This is why the normal distribution is often referred to as the "bell-shaped" distribution. The shape of the curve is a smooth, symmetrical shape that slopes gently and then becomes more steep as it approaches the tails of the distribution.
Finally, it's true that a random variable that follows a normal distribution assumes a value within plus or minus three standard deviations of its mean 99.72% of the time. This is a property of the normal distribution known as the empirical rule or the 68-95-99.7 rule.
In summary, the statement "the graph of the curve is the shape of a rectangle" is not a characteristic of the normal probability distribution, while the other statements are.
Therefore, the degrees of freedom are a feature of statistics that reflect the number of independent observations in a sample that can be used to make inferences about the population.

what is slope intercept?The intersection point in mathematics is the point on the y-axis where the slope of the line intersects. a point on a line or curve where the y-axis intersects. The equation for the straight line is Y = mx+c, where m represents the slope and c represents the y-intercept. The intercept form of the equation emphasises the line's slope (m) and y-intercept (b). The slope of an equation with the intercept form (y=mx+b) is m, and the y-intercept is b. Several equations can be reformulated to seem to be slope intercepts. When y=x is represented as y=1x+0, the slope and y-intercept are both set to 1.
We must solve for y in order to find the slope-intercept form of the equation:
6x + 2y = 4
2y = -6x + 4
y = -3x + 2
As a result, the slope is -3 and the y-intercept is 2.
To graph the line, first plot the y-intercept at the point (0, 2). The slope can then be used to find another point on the line. We can travel down 3 units and right 1 unit to acquire another point on the line because the slope is -3.

Suppose that the weekly demand for kites suddenly goes up to QD=5000−500P.

In the market short run, what will the price of kites be? How much profit will cach kite maker carn'? d. In the market long run, what will the price of kites be? How many new firms will enter the kite-making industry? How much profit will they carr? Be sure to show your work.
Answers
To determine the long-run equilibrium for each firm's production of kites, we need to find the level of output where marginal cost (MC) equals marginal revenue (MR). In perfect competition, firms maximize their profit by producing at the level where MC = MR.
Given the marginal cost function MC = 0.02q, we equate it to the marginal revenue, which is equal to the market price (P) in perfect competition. So, we have:
0.02q = P
Now, we need to find the price at which the quantity demanded (QD) equals the quantity supplied (QS) in the market. To do this, we set QD equal to QS:
QD = QS
Substituting the demand function QD = 4000 - 1000P into the equation, we get:
4000 - 1000P = QS
Now, we can solve for the price (P):
4000 - 1000P = 0.02q
Simplifying further:
1000P = 4000 - 0.02q
P = (4000 - 0.02q) / 1000
Now, we can substitute the value of P into the equation for MC to find the level of output (q):
0.02q = P
0.02q = (4000 - 0.02q) / 1000
Solving for q:
0.02q = 4 - 0.00002q
1.00002q = 4
q = 4 / 1.00002
q ≈ 3999.8
In the long-run equilibrium, each firm will produce approximately 3999.8 kites.
The long-run supply curve for kites in perfect competition is horizontal at the minimum average total cost (ATC) of the firms. This is because in the long run, firms have enough time to adjust their inputs and optimize their production processes, leading to production at the lowest possible cost.
a. To find the number of kites sold and the number of firms in the kite industry, we substitute the price (P) into the demand function QD = 4000 - 1000P:
QD = 4000 - 1000P
QD = 4000 - 1000(4000 - 0.02q) / 1000
Simplifying:
QD = 4000 - 4000 + 0.02q
QD = 0.02q
Since q represents the output per firm and we know that each firm produces around 3999.8 kites, we can substitute this value:
QD = 0.02 * 3999.8
QD ≈ 79.996
Approximately 80 kites will be sold. To find the number of firms in the kite industry, we divide the total quantity supplied by the output per firm:
QS = 3999.8
Number of firms = QS / q
Number of firms = 3999.8 / 3999.8
Number of firms = 1
b. In the very short run, when it is impossible to manufacture any more kites than those produced for that week, the price of kites will be determined by the demand and supply conditions. With the demand function QD = 5000 - 500P, we can find the equilibrium price:
QD = QS
5000 - 500P = QS
Substituting the supply quantity from above:
5000 - 500P = 3999.8
Solving for P:
500P = 5000 - 3999.8
