Step-by-step explanation:

To find the ordered pairs for a successful fundraiser, multiple constraints need to be considered. These include the goal of making $1000 from sales, selling at least twice as many hamburgers as hot dogs, and the physical limit of burgers and hot dogs available.

The problem presents a set of inequalities to be solved. Firstly, to meet the $1000 objective, Jim needs to sell a combination of hamburgers (denoted by y) and hot dogs (x) such that 2x + 3y ≥ 1000. Secondly, he wants to sell at least twice as many hamburgers as hot dogs, which gives: y ≥ 2x. Lastly, Jim has a physical limit on the number of burgers and hot dogs he can sell, which gives: x ≤ 300 and y ≤ 800. The ordered pairs that satisfy all these constraints form the feasible region for Jim’s sales. We are looking for integer values in this region as it is not possible to sell a fractional number of hamburgers or hot dogs. Thus, we need to attentively examine the feasible region on the graph provided. Calculations can also help in confirming the graphical representation.

The system of equations has infinite solutions.

Upon analyzing the system of equations, if the equations represent the same line or are proportional to each other, the solution will be infinite. Let's consider the equations given:

Equation 1: [tex]\(y = x + 1\)[/tex]

Equation 2: [tex]\(2y = 2x + 2\)[/tex]

By manipulating Equation 2, dividing both sides by 2, we get Equation 1. This indicates that the equations represent the same line. When graphed, both equations will yield the same line. Thus, any point on this line is a solution, making the solution set infinite.

Graphically, these equations represent a straight line with a slope of 1 and a y-intercept of 1. Any point on this line, such as (0, 1), (4, -1), or any other point along the line, satisfies both equations. Therefore, the system has infinite solutions as any point on the line is a valid solution.

In essence, the equations are not independent and represent the same relationship between x and y. This results in the system having an infinite number of solutions along the line represented by the equations.

Parallel lines or segments are equidistant from each other and do not intersect. This principle also applies to vectors with identical directions and magnitudes, and to other instances like horizontal lines on a grid or parallel patterns in sentence construction.

Parallel lines or segments are those that are equidistant from each other and never intersect, regardless of how far they extend. In the context of vectors, two vectors are said to be parallel if they have identical directions, denoted by A = B if and only if they have equal magnitudes.

As illustrated in geometry, the horizontal lines on a grid can be parallel. Even visually, parallelism denotes a close resemblance and continuity, as seen in electric field lines drawn parallel to the wire placed on the x-axis.

The horizontal lines in this figure are parallel loops. This is because they remain an equal distance apart at all points. A similar concept of parallel patterns can be seen in grammatical structures and construction of a sentence.

The probability that a randomly selected person from the city who did not vote in the last election is a liberal is about 16.7 percent.

We are trying to find the probability that a person selected at random from the city is a liberal given that they did not vote in the last election. We can use Bayes' theorem and the law of total probability to solve this problem. First, we need to calculate the probability of a person not voting, P(NV), and then find the probability of being a liberal who did not vote, P(L and NV).

The total probability of not voting is P(NV) = P(C) \'97 P(V|C) + P(L) \'97 P(V|L) + P(I) \'97 P(V|I), where P(C) is the probability of being conservative, P(L) is the being liberal, P(I) is the probability of being independent, and P(V|C), P(V|L), P(V|I) are the probabilities of a conservative, liberal, and independent voting, respectively.

So, P(NV) = 0.30 \'97 0.65 + 0.50 \'97 0.82 + 0.20 \'97 0.50 = 0.35 + 0.09 + 0.10 = 0.54. This is the probability that a random person did not vote. Now, we need to find the probability that a person is a liberal and did not vote, P(L and NV) = P(L) \'97 P(NV|L), where P(NV|L) is the probability of a liberal not voting.

P(L and NV) = 0.50 \'97 (1 - 0.82) = 0.50 \'97 0.18 = 0.09. This is the probability that a person is a liberal who did not vote. Finally, to find the probability that a person is a liberal given they did not vote, P(L|NV), we use Bayes' theorem: P(L|NV) = P(L and NV) / P(NV) = 0.09 / 0.54 = 1/6 or approximately 0.167.

In conclusion, the probability that a person selected at random from the city is a liberal given that they did not vote in the last election is about 16.7 percent.

Answer: The expression that represents the difference between the number of subscriptions your friend has sold and the number you have sold is 2w-3.

Explanation:

It is given the expression (5w+1) represents the subscriptions sold by the friend

f(w)=5w+1

Expression (3w+4) represents the subscription sold by me.

g(w)=3w+4

We have to find an expression which shows the difference between the number of subscriptions your friend has sold and the number you have sold.

[tex]h(w)=f(w)-g(w)[/tex]

[tex]h(w)=(5w+1)-(3w+4)[/tex]

[tex]h(w)=5w+1-3w-4[/tex]

Combine like terms.

[tex]h(w)=(5w-3w)+(1-4)[/tex]

[tex]h(w)=2w-3[/tex]

If it is negative then it means the subscription sold by friend is less than the subscription sold by me and if it is positive then it means the subscription sold by friend is more than the subscription sold by me.

The original prices for the baseball cards are $120, $80, and $40.

Let's say the original prices of the first, second, and third baseball cards are x, y, and z respectively.

From the given information, we can form the following equations:

Solving these equations simultaneously, we can find the original prices:

Therefore, the original prices for the first, second, and third baseball cards are $120, $80, and $40 respectively.

Final answer:

The original prices of the 3 baseball cards were $88 for the first card, $56 for the second card, and $96 for the third card, worked out via a system of equations derived from the given information.

Explanation:

We're given that Andrew bought 3 baseball cards for a total of $240. When he sells the first card at double its original value along with the second card at its original price, the total is $320. Conversely, if he sells the first card at double its original value along with the third card, the total is $280.

Let's denote the original prices of the first, second, and third cards as F, S, and T respectively. We have two equations based on the information provided:

2F + S = $320

2F + T = $280

We also know the sum of the original prices:

F + S + T = $240

Subtracting each equation from the combined original price, we get:

S = $240 - T

T = $240 - S

Plugging these into our original equations:

2F + ($240 - T) = $320

2F + ($240 - S) = $280

Solving these equations, we find:

2F = $320 - ($240 - T) => 2F = $80 + T

2F = $280 - ($240 - S) => 2F = $40 + S

Therefore, T - S = $40. Now, using equation 3, F = $240 - S - T, we substitute T = S + $40 to get:

F = $240 - S - (S + $40) => F = $200 - 2S

And if we substitute this into 2F = $80 + T:

2($200 - 2S) = $80 + T

$400 - 4S = $80 + T

T = $320 - 4S

Combining this with T = S + $40, we get:

S + $40 = $320 - 4S => 5S = $280 => S = $56

Now we can find T and F:

T = $56 + $40 => T = $96

F = $200 - 2($56) => F = $88

Thus, the original prices of the baseball cards were $88 for the first card, $56 for the second card, and $96 for the third card.

The bottleneck time for the tortilla chip workstation is 1/50 seconds.

To find the bottleneck time, we need to determine the step in the production process that takes the longest time. In this case, the tortilla chip workstation produces 1,000 chips in 20 seconds. So, each chip takes 20/1000 = 1/50 seconds to produce. Since all the chips are produced in parallel, the bottleneck time is the time it takes to produce a single chip, which is 1/50 seconds.

Answer:

The correct option is A.

Step-by-step explanation:

The given rule of translation is

[tex](x,y) \rightarrow (x-7,y-7)[/tex]        ..... (1)

The rule of translation is defined as

[tex](x,y) \rightarrow (x+a,y+b)[/tex]      ......(2)

Where, a is horizontal translation and b is vertical translation.

If a>0, then graph shifts a units right and if a<0, then graph shifts a units left.

If b>0, then graph shifts b units up and if b<0, then graph shifts b units down.

From equation (1) and (2) we get

[tex]a=-7,b=-7[/tex]

Since a=-7<0 and b=-7<0, therefore graph translated 7 units to the left and 7 units down.

Therefore the correct option is A.
