The marbles kids museum plans to host an event that requires hargett st. To be closed between blount street and person st for a day. Explain whether or not this closure is feasible given the traffic flows described in your model
It is feasible to close Hargett St. between Blount Street and Person Street for a day.
Given the traffic flow model described, it is feasible to close Hargett St. between Blount Street and Person Street for a day. The model states that the average daily traffic flow on Hargett St. is 8,000 vehicles per day, with 3,000 vehicles per hour during peak hours. By closing Hargett St. between Blount Street and Person Street for a day, the average daily traffic flow would be reduced by 8,000 vehicles per day. Thus, the total number of vehicles that would be diverted from Hargett St. on the day of the event would be 8,000 vehicles. This amount of traffic would not be too overwhelming for the surrounding streets to handle, since the model states that the average daily traffic flow for those streets is approximately 4,000 vehicles per day.

Kevin and Mark took a random sample of 100 pieces of trail mix to determine the number of peanuts, raisins, and almonds in a container.
A 3-column table with 3 rows. Column 1 has entries Peanuts, Raisins, Almonds. Column 2 is labeled Kevin's Sample with entries 74, 10, 16. Column 3 is labeled Mark's Sample with entries 45, 17, 38.
If each container of trail mix is known to have 40% peanuts, 40% almonds, and 20% raisins, which sample is a better representation of the actual population?
Mark's sample seems to be a slightly better representation as it is closer to the expected proportions for two out of the three ingredients.
To determine which sample is a better representation of the actual population, we need to compare the proportions of peanuts, raisins, and almonds in each sample with the known proportions in the population.
Let's calculate the expected number of peanuts, raisins, and almonds in the population based on the given percentages. Out of 100 pieces of trail mix in each container, we would expect:
Peanuts: 40% of 100 = 40 peanutsRaisins: 20% of 100 = 20 raisinsAlmonds: 40% of 100 = 40 almondsNow, let's compare the proportions in each sample to the expected proportions:
Kevin's Sample:Peanuts: 74 peanuts out of 100 pieces (74%)Raisins: 10 raisins out of 100 pieces (10%)Almonds: 16 almonds out of 100 pieces (16%)Mark's Sample:Peanuts: 45 peanuts out of 100 pieces (45%)Raisins: 17 raisins out of 100 pieces (17%)Almonds: 38 almonds out of 100 pieces (38%)Comparing the proportions, we can see that neither sample perfectly matches the expected proportions in the population. However, Mark's sample is closer to the expected proportions for peanuts and almonds, while Kevin's sample is closer to the expected proportion for raisins.
Considering the overall representation of the actual population, Mark's sample seems to be a slightly better representation as it is closer to the expected proportions for two out of the three ingredients.
However, it's important to note that both samples deviate from the expected proportions, indicating some sampling variability.

Answer:
x = 48
Step-by-step explanation:
since AB and CD are parallel then
∠ AEF and ∠ DFE are same- side interior angles and sum to 180° , so
72 + 60 + x = 180 , that is
132 + x = 180 ( subtract 132 from both sides )

unlike correlation, the only way to demonstrate causation is to conduct a(n):
The answer to your question is that the only way to demonstrate causation is to conduct a controlled experiment. This domain involves manipulating one variable and measuring the effect it has on another variable while holding all other variables constant.
correlation simply shows a relationship between two variables, but it doesn't prove that one variable causes the other. There could be other factors at play that are influencing both variables. For example, there may be a correlation between ice cream sales and crime rates, but this doesn't mean that ice cream causes crime or vice versa. It's possible that a third variable, such as temperature, is influencing both ice cream sales and crime rates.
further into the complexities of establishing causation, such as the need for random assignment in experimental studies, the importance of replicating findings, and the challenges of applying experimental findings to real-world situations. However, the key point is that a controlled experiment is the most reliable method for establishing a causal relationship between variables.

Answer:
girls = 61
boys = 73
Step-by-step explanation:
Let x = number of girls
Let y = number of boys
Given the difference between the number of the girls and the number of the boys in the outdoors club is 12:
⇒ y - x = 12
Given there are 4 times the number of the girls decreased by 25 equals 3 times the number of the boys:
⇒ 4x - 25 = 3y
Rearrange x - y = 12 to make y the subject:
⇒ y = 12 + x
Substitute x = 12 + y into 4x - 25 = 3y and solve for y:
⇒ 4x- 25 = 3(12 + x)
⇒ 4x- 25 = 36 + 3x
⇒ x = 61
Now we have found the value of x, substitute this into y = 12 + x and solve for y:
⇒ y = 12 + 61
⇒ y = 73

Grant plans to evaporate enough water from 22 gallons of a 16% ammonia solution to make a 24% ammonia solution. Which equation can he use to find n, the number of gallons of water he should remove?
3.52 (22 minus n) = 0.24
StartFraction 22 minus n Over 3.52 EndFraction = StartFraction 24 Over 100 EndFraction
StartFraction 3.52 Over 22 minus n EndFraction = StartFraction 24 Over 100 EndFraction
3.52 + (22 minus n) = 0.24
The equation that he used to find n, the number of gallons of water he should remove is 3.52 / (22 - n) = 24 / 100. Option C is correct.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Amount of ammonia in the solution 16% x 22 gallons = 3.52 gallons
The proportion of ammonia remains the same as the water evaporates, but the total composition of the solution is decreased by the amount of water that evaporates.
Quantity of ammonia = 3.52 gallons
Quantity of water after evaporation = 22 - n
Composition of ammonia after evaporation of water, 24% = 24/100
Now the percentage of ammonia after evaporates
Quantity of ammonia / Remaining water = 24%
3.52 / (22 - n) = 24 / 100
Thus, the equation that he used to find n, the number of gallons of water he should remove is 3.52 / (22 - n) = 24 / 100.

How to find proportional parts in triangles and parallel lines?
If a line parallel to one side of a triangle contacts the other two sides of the triangle, the line proportionally splits these two sides. If DE = BC, then ADDB=AEEC.
If a line parallel to one side of a triangle contacts the other two sides, the two sides are proportionately divided.
The formula for a proportional equation is y = kx. The letters y and x denote the variables in the equation. The letter k represents the proportionality constant, which is fixed.
Because matching angles produce the AA similarity shortcut, when a line is drawn parallel to one side of a triangle, two similar triangles are generated. Because the triangles are comparable, the parallel line segments are proportionate segments.

The equation of the line perpendicular to -x + 2 = y that intersects the line at (-1.5, 3.5) is y + x/2 = 7/2. Here's how to solve it: When writing the equation of a line perpendicular to another line, keep in mind that the slopes of the lines are negative reciprocals of each other.
The equation of the line perpendicular to -x + 2 = y that intersects the line at (-1.5, 3.5) is y + x/2 = 7/2. Here's how to solve it: When writing the equation of a line perpendicular to another line, keep in mind that the slopes of the lines are negative reciprocals of each other. This means that if one line has a slope of m, then a line perpendicular to it has a slope of -1/m. As a result, the slope of the line in the problem is 1/2, which means that the slope of the line perpendicular to it is -2. We'll use point-slope form to determine the equation of the perpendicular line because we have a point (-1.5, 3.5) and a slope (-2).
y - y1 = m(x - x1)
is the point-slope equation, where m is the slope and (x1, y1) is a point on the line that we're using. We can substitute in the values we have to get: y - 3.5 = -2(x + 1.5)
We can simplify this equation: y - 3.5 = -2x - 3y + x/2 = 7/2y + x/2 = 7/2
