Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Why? Select the correct answer below
Answers
It's better to describe the center of distribution in Bakery A using the mean because the data is symmetric, while for Bakery B, the median is preferred due to asymmetric data.
To determine whether it's better to describe the centers of distribution in terms of the mean or the median for each bakery, we need to consider the shape of the data distribution.
For Bakery A:
- The data appears to be relatively symmetric, with values ranging from 34 to 61.
- There are no extreme outliers that significantly skew the data.
For Bakery B:
- The data is not symmetric; there is a wide range of values from 10 to 57.
- There is a notable outlier (10) that is much lower than the rest of the data.
Given these observations:
- For Bakery A, since the data is symmetric and there are no significant outliers, the mean (average) would be an appropriate measure of the center.
- For Bakery B, because the distribution is not symmetric and there is a significant outlier, the median (middle value) would be a more robust measure of the center.
So, the correct answer is:
C) Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric.

Bakery A 45 52 51 48 61 34 55 46
Bakery B 48 42 25 45 57 10 43 46
Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Explain.
A) Mean for both bakeries because the data is symmetric
B) Median because the distribution is not symmetric for both bakeries
C) Mean for Bakery B because the data is symmetric; median for Bakery A because the data is not symmetric
D) Mean for Bakery A because the data is symmetric; median for Bakery B because the data is not symmetric
The correct answer is B): Median because the distribution is not symmetric for both bakeries.
Let's first calculate the mean and median for each bakery:
Bakery A:
Data: 45, 52, 51, 48, 61, 34, 55, 46
Mean (average):
[tex]\[ \text{Mean} = \frac{45 + 52 + 51 + 48 + 61 + 34 + 55 + 46}{8} = \frac{392}{8} = 49 \][/tex]
Median (middle value):
Arrange the data in ascending order: 34, 45, 46, 48, 51, 52, 55, 61
[tex]\[ \text{Median} = \frac{48 + 51}{2} = 49.5 \][/tex]
For Bakery A, the mean is 49 and the median is 49.5. The median (49.5) is slightly higher than the mean (49), indicating a slight right skew in the data.
Bakery B:
Data: 48, 42, 25, 45, 57, 10, 43, 46
Mean (average):
[tex]\[ \text{Mean} = \frac{48 + 42 + 25 + 45 + 57 + 10 + 43 + 46}{8} = \frac{316}{8} = 39.5 \][/tex]
Median (middle value):
Arrange the data in ascending order: 10, 25, 42, 43, 45, 46, 48, 57
[tex]\[ \text{Median} = \frac{43 + 45}{2} = 44 \][/tex]
For Bakery B, the mean is 39.5 and the median is 44. The mean (39.5) is lower than the median (44), indicating a left skew in the data.
Bakery A: The median (49.5) is slightly higher than the mean (49), suggesting a slight right skew. Given this slight skewness, the median might be a better measure of central tendency for Bakery A.
Bakery B: The mean (39.5) is noticeably lower than the median (44), indicating a left skew. Therefore, the median would likely be a better measure of central tendency for Bakery B.
Based on this analysis, the correct answer is B): Median because the distribution is not symmetric for both bakeries.

Answers
Amount of income made by the Smith Household per year= $80000
Amount of money paid by the Smith's per year as school taxes = (2.5/100) * 80000
= 2.5 * 800
= 2000 dollars
So $2000 is the amount that the Smith's household needs to pay as school taxes every year. I hope the procedure needs no further clarification and the answer is what you were looking for.
Final answer:
To calculate school taxes for a household earning an annual income of $80,000 at a tax rate of 2.5%, multiply the income by the rate. The household would pay $2,000 in school taxes.
Explanation:
If a household earns an annual income of $80,000 and the school taxes are 2.5% of the income, the amount paid in school taxes can be calculated by multiplying the income by the tax rate. Here's the calculation:
Tax Amount = Income × Tax Rate
Tax Amount = $80,000 × 0.025
Tax Amount = $2,000
Therefore, a household that earns $80,000 per year would pay $2,000 in school taxes.
What is the value of n in the equation –(2n + 4) + 6 = –9 + 4(2n + 1)?
Answers
Final answer:
The value of n in the equation –(2n + 4) + 6 = –9 + 4(2n + 1) is -2. This is determined by simplifying and solving the given expression for n.
Explanation:
To find the value of n in the equation –(2n + 4) + 6 = –9 + 4(2n + 1), we need to simplify and solve for n. First, we distribute the negative sign and the 4 into the parentheses and then combine like terms:
-2n - 4 + 6 = -9 + 8n + 4
Now, we combine the constants:
-2n + 2 = -5 + 8n
To isolate n, we move all the terms involving n to one side and the constants to the other:
-2n - 8n = -5 - 2
-10n = -7
Finally, we divide by -10 to solve for n:
n = ⅔
Thus, the value of n is -2.

Answer:

Step-by-step explanation:
In physics, if a moving object has a starting position at s 0, an initial velocity of v 0, and a constant acceleration a, then the position S at any time t > 0 is given by:
S = at 2 + v 0 t + s 0.
Solve for the acceleration, a, in terms of the other variables. For this assessment item, you can use ^ to show exponents and type your answer in the answer box, or you may choose to write your answer on paper and upload it.
Answers
a=g
v=⌠g dt
v=gt+vi
s=⌠v
s=gt^2/2+vit+si
So if vi and si are zero then you just have:
s=gt^2/2
Notice that it is not gt^2 but (g/2) t^2
So the first term in any quadratic is half of the acceleration times time squared because of how the integration works out...
Anyway....
sf=(a/2)t^2+vit+si
(sf-si)-vit=a(t^2)/2
2(sf-si)-2vit=at^2
a=(2(sf-si)-2vit)/t^2 and if si and vi equal zero
a=(2s)/t^2
Step-by-step explanation:
The equation of a moving object in physics is given by :
[tex]s=at^2+v_ot+s_o[/tex]...........(1)
Where
s₀ is the starting position of an object
a is the acceleration of the object
v₀ is the initial velocity of the object
t is the time taken
We need to find the value of acceleration by rearranging equation (1). Subtract [tex](v_ot+s_o)[/tex] on both sides of equation (1) as :
[tex]s-v_ot-s_o=at^2[/tex]
Divide both sides of above equation by t² as :
[tex]a=\dfrac{s-v_ot-s_o}{t^2}[/tex]
So, the value of acceleration is [tex]\dfrac{s-v_ot-s_o}{t^2}[/tex]. Hence, this is the required solution.

When a ball is dropped from a state of rest at time t=0t=0, the distance, measured in feet, that it has traveled after tt seconds is given by the formula s(t)=16t2s(t)=16t2 . (use decimal notation. if necessary, give your answer rounded to two decimal places.) (a) how far does the ball travel during the time interval [3, 3.5 ]? distance = .5 feet (b) compute the average velocity over the time interval [3, 3.5 ]. average velocity = 104 feet/sec (c) by computing the average velocity over the time intervals [3, 3.1 ], [3, 3.01 ], and [3, 3.001 ], . . . , estimate the ball's instantaneous velocity at t=3t=3. instantaneous velocity = feet/sec?
Answers
Part A. To solve for the distance travelled during the interval, all we have to do is to plug in values of t = 3 and t = 3.5 in the equation and the difference would be the answer:
when t = 3: s = 16 (3)^2 = 144 m
when t = 3.5: s = 16 (3.5)^2 = 196 m
Therefore the distance travelled within the interval is:
196 m – 144 m = 52 m
Part B. The velocity is calculated by taking the 1st derivative of the equation. v = ds / dt
s = 16 t^2
ds / dt = 32 t = v
when t = 3: v = 32 (3) = 96 m / s
when t = 3.5: v = 32 (3.5) = 112 m / s
Therefore the average velocity is:
(96 + 112) /2 = 104 m / s
Part C. We can still use the formula v = 32 t and plug in the value of t = 3
v = 32 t = 32 (3)
v = 96 m / s
To calculate the distance and velocities for the ball in question, we use the formula s(t)=16t^2, calculate differences, and use limits as the intervals approach an instant.
Explanation:The formula s(t)=16t2 gives the distance s(t) in feet that a ball has traveled after t seconds when dropped from a state of rest. To find the distance during the time interval [3,3.5], we calculate s(3.5) and s(3), and then find the difference: s(3.5) = 16 × (3.5)2 and s(3) = 16 × (3)2.
The average velocity over the interval [3,3.5] is the change in distance divided by the change in time, which is computed as ∆ s/ ∆ t.
For the instantaneous velocity at t=3, we compute the average velocities over smaller and smaller intervals approaching the instant t=3. As these intervals become smaller, the average velocity approaches the instantaneous velocity.

x= -(-2)/2(-1) which is x = 2/-2 which is x = -1. That -1 is the x coordinate of the vertex. You could plug that back into the equation and solve it for y, which is the easier way, or you could complete the square on the quadratic...let's plug in x to find y. -(-1)^2 - 2(-1)-1 = 0. So the vertex is (-1, 0). That's the first choice given. For the last one, since it is a negative quadratic it will be a mountain instead of a cup, meaning it doesn't open upwards, it opens downwards. Those quadratics will ALWAYS have a max value as opposed to a min value which occurs with an upwards opening parabola. This one is also the first choice because of the way the equation is written. There is no side to side movement (the lack of parenthesis tells us that) so the x coordinate for the vertex is 0. The -1 tells us that it has moved down from the origin 1 unit; hence the y coordinate is -1. The vertex is a max at (0, -1)

Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
[tex]f(x) = x^2[/tex]
We need to shift the function f(x) 3 units to the right to obtain the graph of g(x).
As we know that shifting right is the horizontal shift.
And f(x-h) = g(x) , here f shift right h units.
so, After shifting 3 units right, we get that
[tex]g(x)=(x-3)^2[/tex]

Find the vertex, focus, directrix, and focal width of the parabola.
negative 1 divided by 12 times x squared = y
Answers
(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where
(h,k) are the coordinates of the vertex
a is the distance of the vertex to the focus
4a = length of lactus rectum or the focal width
If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis).
The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:
x^2 = -12y
Therefore,
-4a = -12
4a = 12
a = 3, and the parabola is facing downwards.
The vertex is (0,0) at the origin.
The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.
The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3
Focal width is 4a which is equal to 12 units.

The total surface area of the soup can would be equivalent to the sum of the surface area of the 2 covers plus the surface area of the side.
Surface area of the 2 covers = 2 π r^2
Surface area of the 2 covers = 2 π (2.5 cm)^2
Surface area of the 2 covers = 39.27 cm^2
Surface area of the side = 2 π r h
Surface area of the side = 2 π (2.5 cm) (9 cm)
Surface area of the side = 141.37 cm^2
Total surface area = 39.27 cm^2 + 141.37 cm^2

What is the difference between rational functions and inverse variation
Answers
Rational functions are functions that can be written as the ratio of two polynomial functions, while inverse variations are a type of rational function where the product of two varying quantities is a constant.
Explanation:A rational function is any function that can be written as the ratio of two polynomial functions. Both the numerator and the denominator are polynomials. For example, f(x) = (2x^2 + 3)/(x - 5) is a rational function where 2x^2 + 3 and x - 5 are polynomial functions.
On the other hand, an inverse variation, or inverse proportion, is a specific type of rational function where the product of two varying quantities is a constant. It is in the form of y = k/x, where k is a nonzero constant. For example, if y varies inversely as x, then the product of x and y is constant, which means xy = k.
To summarize, all inverse variations are rational functions since they can be expressed as a ratio of two polynomials. However, not all rational functions are inverse variations since not all can be written in the form y = k/x.
