After testing each given point by substituting them into the inequality y > -2x + 5, only the point (1, 4) satisfies the condition, making it the correct answer.
The question is asking to find which point among the options given satisfies the inequality y > -2x + 5. To solve this, we will substitute the x and y values from each option into the inequality and check whether the inequality holds.
For (1, 4), if we substitute x = 1 and y = 4 we get 4 > -2(1) + 5, which simplifies to 4 > 3. Since this is true, this point is a solution.
For (0, 5), if we substitute x = 0 and y = 5 we get 5 > -2(0) + 5, which simplifies to 5 > 5. Since this is not true (it should be strictly greater), this point is not a solution.
For (-2, 8), if we substitute x = -2 and y = 8 we get 8 > -2(-2) + 5, which simplifies to 8 > 9. Since this is not true, this point is not a solution.
For (1, -2), if we substitute x = 1 and y = -2 we get -2 > -2(1) + 5, which simplifies to -2 > 3. Since this is not true, this point is not a solution.
Therefore, the correct answer is the point (1, 4) as it is the only one that satisfies the given inequality.
Jim’s fundraiser BBQ needs to make at least $1000 in sales on Saturday. He sells hot dogs for $2 each and hamburgers for $3 each, and he wants to sell at least twice as many hamburgers as hot dogs. He brought 300 hot dogs and 800 hamburgers to sell. The graph shows the feasible region, where x represents the number of hot dogs sold and y represents the number of hamburgers sold. Which ordered pairs meet all the constraints for a successful fundraiser and make sense in context of the situation? Select each correct answer.
Answer:
Both (0,350) and (250,700) are correct i think
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.
Explanation: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 table lists the number of pitches seen by a player in 6 games. What is the mean of the data set? 11 14.5 18.5 20 Done Game Pitches Seen 1 25 2 20 3 20 4 17 5 15 6 14
The mean of the data set is:
18.5
Step-by-step explanation:The data values are given as:
Done Game Pitches Seen
1 25
2 20
3 20
4 17
5 15
6 14
We know the mean of the data set is calculated as the average of the data values.
Hence, here the mean of the data set is ratio of the total number of pitches to the total number of games.
Total number of pitches=25+20+20+17+15+14=111
Number of games=6
[tex]Mean=\dfrac{111}{6}=18.5[/tex]
Hence, Mean of the data set= 18.5
Which is the least expensive per oz? 12 oz for $5.28 or 18 oz for $7.96. round to the nearest cent?
We see that both of them cost equal.
( As they are approximately of the same cost in cents)
Step-by-step explanation:1)
12 oz for $ 5.28
This means that the rate of 1 oz is:
$ 5.28/12= $ 0.44
Also we know that 1 dollar= 100 cents.
This means that: $ 0.44= 44 cents.
Hence, cost of 1 oz is: 44 cents.
2)
18 oz for $ 7.96
This means that the rate of 1 oz is:
$ 7.96/18= $ 0.4422 cents
Also we know that 1 dollar= 100 cents.
This means that: $ 0.4422= 44.22 cents.
Hence, cost of 1 oz is: 44 cents.
Both are of same cost.
Describe in words the translation represented by the translation rule (x, y) The image is a right pointing arrow. (x – 7, y – 7)
A. 7 units to the left and 7 units down
B. 7 units to the left and 7 units up
C. 7 units to the right and 7 units up
D. 7 units to the right and 7 units down
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.

Suppose you go shopping for a new futon bed for your apartment/home. The model you really like happens to be on sale for $1100. It's original price is $1200. What percent of the original price will you save if you purchase it? Write your answer to the nearest tenth of a percent, but in decimal form. For example, if you saved 34.67%, you would round to 34.7% and enter .347 as your answer.
Answer:
8.3% or 0.083
Step-by-step explanation:
In the question we are given that:
The original price of bed = 1200$
The price of the bed after the discount = 1100$
Money saved = The original price of bed - The price of the bed after the discount = 1200$ - 1100$ = 100$
Percentage of original price = [tex]\frac{\text{Money saved}}{\text{Original price}}\times 100[/tex] = [tex]\frac{100}{1200}\times 100[/tex] = 8.3333..%
If we want to write the answer in the form of nearest tenths, then our percentage becomes 8.3%.
The decimal expansion can be written as 0.083.

Which lines or segments are parallel? Justify your answer.
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.

Sasha Story's salary for a four week period in July was $5,824. What was her weekly salary?
In a certain city, 30 percent of the people are conservatives, 50 percent are liberals, and 20 percent are independents. records show that in a particular election, 65 percent of the conservatives voted, 82 percent of the liberals voted, and 50 percent of the independents voted. if a person in the city is selected at random and it is learned that she did not vote in the last election, what is the probability that she is a liberal?
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.

Andrew bought 3 baseball cards for $240. After a few months, he got an offer from his friend Jack to buy the first card for double its original value, along with either the second or third card. Andrew decided to sell the first card (at double its original value) along with the second card (at its original price) and got $320 for it. Or, selling the first card (at double its original value) card along with the third card (at its original price) would have only got him $280. What were the original prices for each of the 3 baseball cards?
The original prices for the baseball cards are $120, $80, and $40.
Explanation: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:
2x + y = 320 2x + z = 280 x + y + z = 240
Solving these equations simultaneously, we can find the original prices:
x = $120 y = $80 z = $40
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.

Caroline saves $45 in 4 months. at that rate, how long will it take her to save $180?
Caroline saves the amount of $180 in 12 months which is determined by the proportion of the given rate.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other. Proportions are represented by the symbols "::" or "=".
We have been given that Caroline saves $45 in 4 months.
To determine the time takes her to save $180
Let the number of months takes her to save $180 would be x
As per the given condition, we can write a proportion as
4 months : $45 = x months : $45
⇒ 4 / 45 = x / 180
Apply the cross-multiplication operation,
⇒ 4 × 180 = x × 45
⇒ 540 = 45x
⇒ x = 540 / 45
⇒ x =12
Therefore, Caroline saves the amount of $180 in 12 months.
