Step-by-step explanation:
You want the x-coordinate of the point where the lines on the graph cross.
Equilibrium pointThe equilibrium point, as the problem statement tells you, is the point where the two lines have the same x- and y-values. That is the point where the lines cross.
The problem statement also tells you that the x-coordinate represent the number of games, in thousands, that will be sold at the price represented by the y-coordinate. By asking for the number of games sold, the question is asking for the x-coordinate of the point where the lines cross.
The lines cross at a grid intersection that is 4 squares right of the y-axis. The label 10 on the 5th square tells you that each square represents 2 (thousands). Hence the x-coordinate of the equilibrium point is ...

There are 5 × 3 = 15 possible ordered pairs. Therefore, n(B × C) = 15.
Describe Cartesian Product?In mathematics, the Cartesian product is a binary operation that takes two sets and forms a set consisting of all possible ordered pairs of elements from the two sets. The resulting set is often denoted by A × B, where A and B are the two original sets.
Formally, if A and B are two sets, the Cartesian product A × B is defined as:
A × B = {(a, b) : a ∈ A and b ∈ B}
This means that the Cartesian product contains all possible ordered pairs (a, b) where a is an element of A and b is an element of B. For example, if A = {1, 2} and B = {x, y}, then A × B would be {(1, x), (1, y), (2, x), (2, y)}.
The Cartesian product B × C is the set of all ordered pairs (b, c) where b is an element of B and c is an element of C. Since B has 5 elements and C has 3 elements, there are 5 × 3 = 15 possible ordered pairs. Therefore, n(B × C) = 15.

A 500-gallon tank initially contains 200 gallons of brine containing 90 pounds of dissolved salt. Brine containing 3 pounds of salt per gallon flows into the tank at the rate of 4 gallons per minute, and the well-stirred mixture flows out of the tank at the rate of 1 gallon per minute. Set up a differential equation for the amount of salt A(t) in the tank at time t.
How much salt is in the tank when it is full?
The differential equation for the amount of salt A(t) in the tank at time t is 12 - A(t)/(200 + 3t) and the amount of salt in the tank when it is full is 290.72 pounds.
To set up a differential equation for the amount of salt A(t) in the tank at time t, we need to determine how the amount of salt changes over time. The rate of change of the amount of salt in the tank is determined by the difference between the rate at which salt flows into the tank and the rate at which salt flows out of the tank.
Since the incoming brine contains 3 pounds of salt per gallon, the rate at which salt flows into the tank is 3 pounds per gallon times 4 gallons per minute, or 12 pounds per minute. Since the mixture flows out of the tank at a rate of 1 gallon per minute, the rate at which salt flows out of the tank is A(t)/V(t), where V(t) is the volume of the mixture in the tank at time t.
Since the volume of the mixture in the tank at time t is the sum of the initial volume and the volume of incoming brine minus the volume of outgoing mixture, we have:
V(t) = 200 + 4t - t = 200 + 3t
Therefore, the rate at which salt flows out of the tank is A(t)/(200 + 3t) pounds per minute. Thus, the differential equation for the amount of salt A(t) in the tank at time t is:
dA/dt = 12 - A(t)/(200 + 3t)
To find the amount of salt in the tank when it is full, we need to find the time t when the tank is full. The tank is full when its volume is 500 gallons, so we have:
200 + 4t - t = 500
Simplifying this equation, we get:
3t = 300
t = 100
Therefore, the tank is full after 100 minutes. To find the amount of salt in the tank when it is full, we can solve the differential equation for A(t) using an appropriate initial condition (i.e., the amount of salt in the tank at t=0):
dA/dt = 12 - A(t)/(200 + 3t)
A(0) = 90
Solving this differential equation, we get:
A(t) = 360 - 270e^(-t/300)
Therefore, the amount of salt in the tank when it is full (i.e., after 100 minutes) is:
A(100) = 360 - 270e^(-1/3)
which is approximately 290.72 pounds.

You may need to use the appropriate table in the Appendix of Tables to answer this question.
(a) 0.52, (b) -0.54, (c) 0.68, (d) -0.71, (e) -1.44 - Percentiles for standard normal distribution using z-table.
(a) To find the 71st percentile, we search for the z-score that relates to a combined area of 0.71 to one side of the mean. From the standard typical circulation table, we find that the nearest z-scores are 0.67 and 0.72, with relating areas of 0.7486 and 0.7642, individually. To interject, we utilize the equation:
z = z1 + (z2 - z1) * ((p - p1)/(p2 - p1))
where z1 and z2 are the nearest z-scores in the table, p1 and p2 are the comparing regions, and p is the ideal total region (0.71). Connecting the qualities, we get:
z = 0.67 + (0.72 - 0.67) * ((0.71 - 0.7486)/(0.7642 - 0.7486)) = 0.52
Consequently, the 71st percentile is z = 0.52.
(b) To find the 29th percentile, we search for the z-score that compares to a combined area of 0.29 to one side of the mean. From the standard ordinary conveyance table, we find that the nearest z-scores are - 0.53 and - 0.52, with relating areas of 0.2981 and 0.3050, individually. To add, we utilize the recipe:
z = z1 + (z2 - z1) * ((p - p1)/(p2 - p1))
where z1 and z2 are the nearest z-scores in the table, p1 and p2 are the comparing regions, and p is the ideal total region (0.29). Connecting the qualities, we get:
z = - 0.53 + (- 0.52 - (- 0.53)) * ((0.29 - 0.2981)/(0.3050 - 0.2981)) = - 0.54
Consequently, the 29th percentile is z = - 0.54.
(c) To find the 76th percentile, we search for the z-score that relates to an aggregate area of 0.76 to one side of the mean. From the standard ordinary appropriation table, we find that the nearest z-scores are 0.73 and 0.77, with relating areas of 0.7673 and 0.7794, separately. To interject, we utilize the equation:
z = z1 + (z2 - z1) * ((p - p1)/(p2 - p1))
where z1 and z2 are the nearest z-scores in the table, p1 and p2 are the comparing regions, and p is the ideal total region (0.76). Connecting the qualities, we get:
z = 0.73 + (0.77 - 0.73) * ((0.76 - 0.7673)/(0.7794 - 0.7673)) = 0.68
Consequently, the 76th percentile is z = 0.68.
(d) The 24th percentile compares to a z-score of - 0.71, meaning 24% of the standard ordinary conveyance misleads its left.
(e) The seventh percentile relates to a z-score of - 1.44, meaning 7% of the standard typical conveyance misleads its left.

Triangle ABC is similar to triangle FGH. Given the following angle measures, find the missing angle measures.
m∠A = 22 degrees
m∠B = 75 degrees
m∠F = _____ degrees
m∠G = _____ degrees
m∠H = _____ degrees
m∠C = _____ degrees
Answer:
Since triangle ABC is similar to triangle FGH, their angle measures are proportional. We can use the ratios of their angle measures to find the missing angle measures.
Let's call the missing angle measures x, y, z, and w, where x is m∠F, y is m∠G, z is m∠H, and w is m∠C.
From the given information, we have:
m∠A / m∠F = 22 / x
m∠B / m∠G = 75 / y
Since m∠A + m∠B + m∠C = 180 degrees, we can write:
w = 180 - (m∠A + m∠B)
m∠H / m∠C = z / w
Now we can use the ratios to find the missing angle measures:
x = 22 / (22 / x) = 22
y = 75 / (75 / y) = 75
z = m∠H / (m∠H / z) = m∠H
w = 180 - (22 + 75) = 83
So, the missing angle measures are:
m∠F = 22 degrees
m∠G = 75 degrees
m∠H = m∠H (unknown)
m∠C = 83 degrees

A deck of cards contains RED cards numbered 1,2,3,4,5 and BLUE cards numbered 1,2,3,4. Let R be the event of drawing a red card, B the event of drawing a blue card, E the event of drawing an even numbered card, and O the event of drawing an odd card. Drawing the Red 5 is one of the outcomes in which of the following events? Select all correct answers.
The probability of drawing the red 5 is an example of the event shown in option E R'. E' = 1-Pr(R)-1-Pr(E)
What is probability?Probability in mathematics is the process of finding chances of an event to happen.
Given that, a deck of card have,
Red cards = 1,2,3
Blue cards =1,2,3,4,5,6
Pr(R) = Drawing a red card = 3/9 = 1/3
Pr(B) = Drawing a blue card = 6/9 = 2/3
Pr(E) = Drawing an even card = 4/9
Pr(O) = Drawing an odd number card = 5/9
Probability of drawing the red 5 = P(red 5) = 1/9
From the options, we have :-
(A) R or O = Pr(R) + Pr(O) = 1/3 + 1/9 = 8/9 ≠ 1/9
(B) B and O = Pr(B) × Pr(O) = 2/3 × 5/9 = 10/21 ≠ 1/9
(D) R and O = Pr(R) + Pr(O) = 1/3 × 5/9 = 5/27 ≠ 1/9
(E) R'. E' = 1-Pr(R)-1-Pr(E) = 1-1/3 =2/3- 1-4/9 =5/9
= 2/3-5/9
= 1/9
Hence, the probability of drawing the red 5 is an example of the event shown in option E R'. E' = 1-Pr(R)-1-Pr(E)
