Eva left her house at time zero and drove to the store, which is 3 blocks away, at a
speed of 1 block per minute. Then she stopped and went into the store for 3 minutes.
From there, she drove in the same direction at a speed of 1 block every 2 minutes
until she got to the bank, which is 3 blocks away from the store. She stopped at the
bank for 6 minutes. Then she drove home at a speed of 1 block every minute. Make a
graph of showing the number of blocks away from home that Eva is a minutes after
she leaves her house, until she gets back home.
Answers
The function f(x), representing the number of blocks Eva is away from her house after x minutes is
\(f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}\)
The graph for the same is attached.
In the question, we are asked to form a graph showing the number of blocks, that Eva is away from her home at x minutes, after she leaves her home.
To form the graph, we first try to make a function for x minutes, f(x), showing the number of blocks Eva is away from her home after x minutes.
Since x represents time, it cannot be negative.
At x = 0, f(x) = 0, as she is at her home at 0 minutes.
Then, Eva visits the store, 3 blocks away from her home at a speed of 1 block per minute.
Thus, she moves 1 block every minute up to 3 minutes.
Thus, we get f(x) = x, 0 < x ≤ 3.
After this, she spends 3 minutes at the store, giving f(x) = 3, 3 < x ≤ 6.
Then she moves towards the bank, in the same direction, 3 blocks away at the speed of 1 block every 2 minutes.
Thus, in every minute, she travels 1/2 block.
Thus, the function can be designed as follows:
f(x) = 3 + (1/2)(x - 6), 6 < x ≤ 12,
or, f(x) = x/2, 6 < x ≤ 12.
Now, we are given that she stops at the bank for 6 minutes.
Thus, we get, f(x) = 6, 12 < x ≤ 18.
Now, she drove back home, at the speed of one block every minute.
Thus, we get f(x) = 6 - (x - 18), 18 < x ≤ 24,
or, f(x) = 24 - x, 18 < x ≤ 24.
At the 24th minute, Eva reaches her house back, giving f(x) = 0, x > 24.
Thus, the complete function can be shown as:
\(f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}\)

Answers
I ⊆ I' if and only if a' ≤ a and b ≤ b'. This relationship holds true for closed intervals I and I' in R. To show that I ⊆ I' if and only if a' ≤ a and b ≤ b', we will consider two cases:
1. If I ⊆ I', then for any x ∈ I, we have x ∈ I'. Since I and I' are closed intervals, we can write them as I = [a, b] and I' = [a', b']. We want to show that a' ≤ a and b ≤ b' in this case.
Since x ∈ I, we know that a ≤ x ≤ b. Now, since x also belongs to I', we have a' ≤ x ≤ b'. Since this is true for any x in I, we can conclude that a' ≤ a and b ≤ b'.
2. If a' ≤ a and b ≤ b', we want to show that I ⊆ I'. Let x be any element in I, so we have a ≤ x ≤ b. We are given that a' ≤ a and b ≤ b'. Since a' ≤ a and a ≤ x, we can infer that a' ≤ x. Similarly, since x ≤ b and b ≤ b', we can infer that x ≤ b'. Therefore, x ∈ I'.
Since x was an arbitrary element in I, we can conclude that I ⊆ I' when a' ≤ a and b ≤ b'.
In summary, I ⊆ I' if and only if a' ≤ a and b ≤ b'. This relationship holds true for closed intervals I and I' in R.

we are told that 7% of college graduates, under the age of 20 are unemployed. what is the probability that at least 200 out of 210 college graduates under age 20 are employed?
Answers
P(X ≥ 200) = 1 - P(X < 200) ≈ 1.0. In other words, it is very likely (almost certain) that at least 200 out of 210 college graduates under age 20 are employed.
To find the probability that at least 200 out of 210 college graduates under age 20 are employed, we can use the binomial distribution formula:
P(X ≥ 200) = 1 - P(X < 200)
where X is the number of employed college graduates under age 20 out of a sample of 210.
We know that the unemployment rate for college graduates under the age of 20 is 7%. Therefore, the probability of an individual college graduate being unemployed is 0.07.
To find the probability of X employed college graduates out of 210, we can use the binomial distribution formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where n is the sample size (210), k is the number of employed college graduates, and p is the probability of an individual college graduate being employed (1-0.07=0.93).
We want to find P(X < 200), which is the same as finding P(X ≤ 199). We can use the cumulative binomial distribution function on a calculator or software to find this probability:
P(X ≤ 199) = 0.000000000000000000000000000001004 (very small)
Therefore, P(X ≥ 200) = 1 - P(X < 200) ≈ 1.0. In other words, it is very likely (almost certain) that at least 200 out of 210 college graduates under age 20 are employed.

Answers
The population density of Philadelphia is approximately 11,761.76 people per square mile, while the population density of Pottstown is approximately 4,672.16 people per square mile.
To compare the densities of Philadelphia and Pottstown, we need to calculate the population density for each city. Population density is typically measured as the number of individuals per unit area.
For Philadelphia:
Population = 1,579,000
Land area = 134.28 sq miles
Population density = Population / Land area
Population density = 1,579,000 / 134.28
Population density \(^\sim_\sim\) 11,761.76 people per square mile
For Pottstown:
Population = 22,670
Land area = 4.85 sq miles
Population density = Population / Land area
Population density = 22,670 / 4.85
Population density \(^\sim_\sim\) 4,672.16 people per square mile
Therefore, the population density of Philadelphia is approximately 11,761.76 people per square mile, while the population density of Pottstown is approximately 4,672.16 people per square mile.
Comparing the two, we can see that Philadelphia has a higher population density compared to Pottstown.

Steps to derive the correct option :Given :Lines u and v are parallel Measure of an angle = 12x - 4Measure of it's corresponding angle = 10x + 10Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.
Which means :
\( = \tt12x - 4 = 10x + 10\)
\( = \tt12x - 4 - 10x = 10\)
\( = \tt12x - 10x = 10 + 4\)

now imagine inserting a 40 cm spoon so that it makes a 60◦ angle with the normal to the interface. what angle does the spoon appear to make with the normal to the interface when it is submerged?
Answers
When the spoon is submerged, it will appear to make a different angle with the normal to the interface than when it was inserted.
This is due to the phenomenon of refraction, where light waves bend as they pass from one medium to another. The angle of refraction can be calculated using Snell's law. In this case, assuming the medium above the interface is air and the medium below is water, the angle of refraction will be approximately 42◦. Therefore, the spoon will appear to make a 42◦ angle with the normal to the interface when it is submerged.
When a spoon is inserted into water at a 60° angle with the normal to the interface, the angle at which it appears to the observer will be different due to the phenomenon of refraction. To find the apparent angle, you can use Snell's Law: n1 * sinθ1 = n2 * sinθ2, where n1 and n2 are the refractive indices of air and water, respectively, and θ1 and θ2 are the incident and refracted angles.
For air, n1 ≈ 1, and for water, n2 ≈ 1.33. With θ1 = 60°, you can calculate θ2:
sinθ2 = (n1 * sinθ1) / n2
θ2 = arcsin((1 * sin60°) / 1.33)
Solving for θ2 will give you the apparent angle of the submerged spoon with respect to the normal to the interface.

Answers
The portfolio weights for stock A and stock B are approximately 55.69% and 44.31%, respectively.
To calculate the portfolio weights for stock A and stock B, we need to determine the total value of the portfolio and the proportion of each stock's value within that total.
The total value of the portfolio can be calculated as follows:
Total value = (Number of shares of stock A × Price per share of stock A) + (Number of shares of stock B × Price per share of stock B)
Total value = (135 × $84) + (110 × $82)
Total value = $11,340 + $9,020
Total value = $20,360
Now, we can calculate the portfolio weights for each stock:
Weight of stock A = (Value of stock A ÷ Total value) × 100%
Weight of stock A = (($84 × 135) ÷ $20,360) × 100%
Weight of stock A = $11,340 ÷ $20,360
Weight of stock A ≈ 0.5569 or 55.69%
Weight of stock B = (Value of stock B ÷ Total value) × 100%
Weight of stock B = (($82 × 110) ÷ $20,360) × 100%
Weight of stock B = $9,020 ÷ $20,360
Weight of stock B ≈ 0.4431 or 44.31%

ashley and her brother mason are building block towers. ashley's 1-meter tower is 10 blocks high. mason's tower is only 7 blocks high. if all of the blocks are the same size, how many centimeters taller is ashley's tower than mason's?
Answers
Ashley's tower is 30 centimeters taller than Mason's tower. Ashley's tower is 10 x (1/10) = 1 meter tall. Mason's tower, on the other hand, is 7 x (1/10) = 0.7 meters tall.
Ashley's tower is 10 blocks high and each block has a height of 0.1 meters since 1 meter is divided into 10 equal parts. Therefore, the total height of Ashley's tower is 10 x 0.1 = 1 meter. Mason's tower, on the other hand, is 7 blocks high and has a total height of 7 x 0.1 = 0.7 meters. The difference between Ashley's tower and Mason's tower is the height of Ashley's tower minus the height of Mason's tower, which is 1 meter - 0.7 meters = 0.3 meters. To convert meters to centimeters, we need to multiply by 100, so Ashley's tower is 0.3 x 100 = 30 centimeters taller than Mason's tower.

Answers
We can use the ideal gas law and the mass rate formula to calculate the time required for the pressure to be reduced from an initial 1000 kPa to a pressure of 500 kPa. The time t is 32.95 hours.
The law of perfect gases is also known as Ideal Gas Law. It describes the behavior of a gas when all its variables are kept constant. It is given as follows:
pV = nRT
Where p is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
The unit for pressure is Pascals (Pa), volume is cubic meters (m³), number of moles is moles (mol), gas constant is joules per Kelvin per mole (J/mol.K), and temperature is Kelvin (K).
We have constant volume (V) and temperature (T), and we are considering only pressure (p) as the variable. We can use this formula:
dm/dt = -pA√(RT/M)
The rate of mass is (dm/dt), pressure is p, the area of the hole is A, R is the gas constant, T is the temperature, and M is the molar mass of the gas.
The negative sign indicates that the mass rate is flowing out of the tank
We have:
Initial pressure (P1) = 1000 kPa
Final pressure (P2) = 500 kPa
Leakage rate (m) = 0.66pA√(RT/M)
The leakage rate can be written as dm/dt = -0.66pA√(RT/M)
We have a constant volume (V), so we can write:
pV = nRT
The number of moles can be written as:
n = (pV)/(RT)
We can use this formula for the ideal gas law:
pV = nRT
We can substitute this into our mass rate formula to get:
-0.66pA√(RT/M) = -dm/dt(pV/M) (A)(√(RT/M))
Substitute the values of A, p, R, T, M, P1, and P2 to get:
\((1000*5*10⁻⁶)/(39.9*516*(273+27)) = ln(1000/500)\)
\(t = (5*10⁻⁶)/(0.66*(10⁻⁶)*√(516*5*39.9/0.66))*(ln(1000/500))\)
t = 32.95 hours
We can use the ideal gas law and the mass rate formula to calculate the time required for the pressure to be reduced from an initial 1000 kPa to a pressure of 500 kPa. We can write pV = nRT to get the number of moles as n = (pV)/(RT).
We can substitute this into our mass rate formula to get -
\(0.66pA √(RT/M) = -dm/dt(pV/M)(A)(√(RT/M)).\)
We substitute the values of A, p, R, T, M, P1, and P2 to get \((1000*5*10⁻⁶)/(39.9*516*(273+27)) = ln(1000/500).\)
The time is t = \((5*10⁻⁶)/(0.66*(10⁻⁶)*√(516*5*39.9/0.66))*(ln(1000/500)),\)which is 32.95 hours.

Answer:
A. 4 2/3
Step-by-step explanation:

a store prints a request on each receipt asking customers to fill out a satisfaction survey online if they are willing. what type of sample is this?
Answers
The type of sample that a store prints a request on each receipt asking customers to fill out a satisfaction survey online if they are willing is a voluntary response sample.
In the statistics world, a voluntary response sample is a research sample that relies on individual self-selection. This is in opposition to random sampling, in which the samples are gathered in a way that ensures everyone in a particular population has an equal chance of being chosen. This method of self-selection is also known as self-selection bias or sampling bias.Voluntary response samples are subject to a variety of flaws. The responses may not be representative of the population as a whole, and they may be skewed by numerous factors, such as which individuals are most likely to volunteer, how these volunteers differ from the population as a whole, and how the survey questions are phrased.The results of a voluntary response survey may be useful in generating hypotheses or gaining a general sense of how individuals feel about a particular subject. However, they are not reliable enough to draw any conclusions or to be taken seriously in the scientific sense.
