Answer:
The population changed by 4.19%. The population shrank.
0.0419.
Step-by-step explanation:
We have been given that the population in Rochester, New York, was 219,773 people in 2000 and 210,565 people in 2010.
[tex]\text{Percent change}=\frac{\text{Final}-\text{Initial}}{\text{Initial}}\times 100[/tex]
[tex]\text{Percent change}=\frac{210,565-219,773}{219,773}\times 100[/tex]
[tex]\text{Percent change}=\frac{-9,208}{219,773}\times 100[/tex]
[tex]\text{Percent change}=-0.04189777\times 100[/tex]
[tex]\text{Percent change}=-4.189777\%[/tex]
[tex]\text{Percent change}\approx-4.19\%[/tex]
Therefore, the population changed by 4.19%.
Since the percent change is negative, therefore, the population decreased or shrank over the given period.
[tex]4.19\%=\frac{4.19}{100}=0.0419[/tex]

A triangle has vertices at L(2, 2), M(4, 4), and N(1, 6). The triangle is transformed according to the rule R0, 180°. Which statements are true regarding the transformation? Check all that apply. The rule for the transformation is (x, y) → (–x, –y). The coordinates of L' are (–2,–2). The coordinates of M' are (–4,4). The coordinates of N' are (6,–1). The coordinates of N' are (–1,–6).
Transformation involves changing the coordinates of a shape
The true statements regarding the transformation are: (a), (b) and (e)
The transformation rule is given as: R0, 180°
This means 180 degrees rotation
A 180 degrees rotation is represented as: (x, y) → (–x, –y) --- option (a)
So, we have:
L'= (-2,-2) --- option (b)
M' = (-4,-4)
N = (-1,-6) -- option (e)

the point slope form of X-3Y=-27
The equation in point slope form as -
y - 18 = (1/3)(x - 27)
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line in point slope form can be also written as-
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
We have the following equation -
x - 3y = -27
We can write the equation as -
x - 3y = -27
Rearranging, we get -
3y = x + 27
y = x/3 + 9
Plot the graph. The line passes through the point (27, 18). So, we can write the equation in point slope form as -
y - 18 = (1/3)(x - 27)
Therefore, the equation in point slope form as -
y - 18 = (1/3)(x - 27)

The point slope form of the equation X - 3Y = -27 is Y = (1/3)X + 9. This equation represents a line with a slope of 1/3 and a y-intercept of 9.
Explanation:The point slope form of the equation X - 3Y = -27 is Y = (1/3)X + 9.
To convert the given equation to point slope form, isolate Y by subtracting X from both sides: -3Y = -X - 27. Then, divide both sides by -3 to solve for Y: Y = (1/3)X + 9.
This equation represents a line with a slope of 1/3 and a y-intercept of 9. This means that for every 1 unit increase in X, Y will increase by 1/3, and the line will intersect the y-axis at the point (0, 9).

(90% confidence level z*-score of 1.645) Remember, the margin of error, E, can be determined using the formula E = z*. To the nearest tenth of a percent, the margin of error for the poll is %.
THE ANSWER IS 3.6% BECAUSE I JUST TOOK THE TEST AND GOT A 100%
Answer:
3.6%
Step-by-step explanation:
Given that A recent poll of 380 randomly selected Americans showed that 24% ( = 0.24) are happy with their cell phone carriers.
Sample size n =380
Sample proportion p = 0.24
q = 1-0.24 =0.76
Std error of p = [tex]\sqrt{\frac{pq}{n} } =0.0219[/tex]
Z critical value for 90% would be 1.645
Margin of error = ±1.645*std error

) Why is the price system a more efficient system for allocating scarce resources than by authoritarian means, such as in command economies?
Step-by-step explanation:
Lets look at each of the options one by one:
Price System: In this system markets allocate resources through the price mechanism. An increase in demand raises price and encourages businesses to use more resources into the production of that good or service. In this system the government limits itself to protecting property rights of people and businesses using the legal system and protecting the value of money or the value of a currency.
Authoritarian System: In this system it is associated with a communist system. The scarce resources are owned by the government. The state allocates resources, and sets production targets and growth rates according to its own view of people's wants. They have their own idea of demand.
By comparing two systems it can be seen that Price System automatically moves resources to where they are most needed. So, price system is more efficient than authoritarian means.

After a discount Joan paid $700 for a new laptop and an additional 5% tax on the marked price.
What is the marked price of the laptop if Joan paid a total of $737?
Question 5 options:
$700
$777
$740
$40
The correct marked price of the laptop is $740.
To find the marked price of the laptop, we need to consider the total amount Joan paid, which includes the discounted price and the additional tax. Joan paid a total of $737, which is after a discount and including a 5% tax on the marked price.
Let's denote the marked price of the laptop as M. Joan paid $700 after the discount, which means the discounted price is $700. The tax paid on the marked price is 5% of M, which can be written as 0.05M .
The relationship between the marked price, the discount, and the tax can be expressed as:
[tex]\[ M - \text{Discount} + 0.05M = \text{Total paid} \] \[ M - (M - 700) + 0.05M = 737 \] \[ M - M + 700 + 0.05M = 737 \] \[ 0.05M = 737 - 700 \] \[ 0.05M = 37 \][/tex]
Now, we solve for \( M \) to find the marked price:
[tex]\[ M = \frac{37}{0.05} \] \[ M = 740 \][/tex]
Therefore, the marked price of the laptop is $740.
The other options can be eliminated as follows:
- $700 is the price Joan paid after the discount, not the marked price.
- $777 is not correct because it does not account for the 5% tax on the marked price.
- $40 is incorrect as it is much less than the amount Joan paid after the discount.
Hence, the correct answer is $740 for the marked price of the laptop.

From the graph we can see that point G is the barycentre of the triangle, because it's formed by the intersection of the three medians of the triangle, which are defined as segments from a vertex to the midpoint of the opposite side.
From the intersection of all triangle medians we have that:
[tex]BG=2GE[/tex]
[tex]CG=2GF[/tex]
[tex]AG=2GD[/tex]
Also, we know by hypothesis that [tex]GE=27[/tex]. Replacing this value:
[tex]BG=2GE[/tex]
[tex]BG=2(27)=54[/tex]
Then, by sum of segments, we have:
[tex]BE=BG+GE[/tex]
[tex]BE=54+27=81.[/tex]
Therefore, BE = 81.

Shirley wants to buy a skateboard for $64. She has $98 in her account. She spent $10.85 to buy stationary. She also wants to buy some cookies for $1.65 each. What is the maximum number of cookies, n, that Shirley can buy so that she has enough money left to buy the skateboard? a. n ≥ 14 b. n ≤ 16 c.n ≤ 14 d.n ≥ 16
Answer:
n ≤ 14
Step-by-step explanation:
Shirley wants a skateboard that's $64. She has $98. She spent $10.85. She wants to spend some money on a couple cookies $1.65 each. So $1.65* 14= $23.10
23.10+10.85+64= 97.95
while
$1.65*16= 26.4
26.4+ 10.85+ 64= 101.25
So, it would have to be that n is less than or equal to 14.
The maximum no of cookies is n ≤ 14.
Given that,
The purchase price of the skateboard is $64.The amount in the account is $98.The spending amount is $10.85.The per cookie price is $1.65.Based on the above information, the calculation is as follows:
The amount after spending to stationary is
= $98 - $0.5
= $87.15
And,
The remaining amount is
= $87.15 - $64
= $23.15
Now
1.65n≤23.15
n≤[tex]23.15\div1.65[/tex]
n≤14
Therefore we can conclude that the maximum no of cookies is n ≤ 14.

Given: A parallelogram JKLM is shown where segment JM is parallel to segment KL and segment JK is parallel to segment ML.
To prove: Opposite angles of parallelogram are equal.
Construction: Extend segment JM beyond point M and draw point P, Extend segment JK beyond point J and draw point Q.
Proof:
It is given that A parallelogram JKLM is shown where segment JM is parallel to segment KL and segment JK is parallel to segment ML.
Extend segment JM beyond point M and draw point P--------By construction
