Step-by-step explanation:
The cost to make each T-shirt is $10. You estimate that you will
sell 50 shirts. If you want to make a profit of at least $250, what
price will you charge for these T-shirts? Show your solution in two
different ways.
The price per T-shirt should be at least $15 to achieve a profit of $250.
To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.
Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.
Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.
Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.
Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.
By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

at what two distances from the base of the stump after it jumped was the frog 4.3 ft above the ground
Let's assume that the initial velocity of the frog is zero. Using the kinematic equations of motion, the height of the frog at any time can be determined as given below.
s = ut + 1/2at², where s is the distance, u is the initial velocity, a is the acceleration, and t is the time taken.
Here, s = 1.24 m - h (since the initial height of the frog is 1.24 m), u = 0 (since the initial velocity of the frog is zero),
a = -9.8 m/s² (the acceleration due to gravity), and t is the time taken. Let's assume that the frog reaches the ground after t seconds. Hence, 4.3 ft = 1.3 m
The height of the frog when it is at 4.3 ft above the ground can be written as: 1.3 m = -4.9t² + 1.24 m
By solving the above equation for time, we get, t = 0.575 s. The time taken by the frog to reach the ground is 0.575 seconds. Therefore, the horizontal distance traveled by the frog can be determined as: d = vt, where d is the horizontal distance, v is the velocity of the frog, and t is the time taken. v can be determined using the formula:
v = u + at. Here, u = 0 (since the initial velocity of the frog is zero), a = -9.8 m/s² (the acceleration due to gravity), and t is the time taken. Hence, v = -9.8 x 0.575 = -5.63 m/s. Thus, the horizontal distance traveled by the frog is given by:
d = vt = -5.63 x 0.575 = -3.24 m. Since the distance cannot be negative, the horizontal distance traveled by the frog is 3.24 m. Using the same method, we can determine the horizontal distance traveled by the frog in the other direction. Therefore, the two distances from the base of the stump where the frog was 4.3 feet above the ground after it jumped are 3.24 m and -3.24 m.

There are N spaces.
A red ball and a blue ball can be in the same space.
The number of red balls is A.
The number of blue balls is B.
N=A+B
What is the number of cases(the density of states) where red and blue balls fill only a quarter of N spaces?
The total number of cases or density of states where red and blue balls fill only a quarter of N spaces is given by the product: C(N, A) * C(N, B).
Let's assume that the total number of spaces is N, and the number of red balls is A, while the number of blue balls is B. Since N = A + B, the remaining (N - A - B) spaces are unoccupied.
To calculate the number of cases where red and blue balls fill only a quarter of N spaces, we need to choose a quarter of N spaces for the red balls and a quarter of N spaces for the blue balls.
The number of ways to choose a quarter of N spaces for the red balls is given by the binomial coefficient: C(N, A), which represents the number of combinations of N spaces taken A at a time.
Similarly, the number of ways to choose a quarter of N spaces for the blue balls is C(N, B).
Therefore, the total number of cases or density of states where red and blue balls fill only a quarter of N spaces is given by the product: C(N, A) * C(N, B).
By calculating this product, we can determine the number of cases satisfying the given conditions.

Find the missing value in the equivalent ratio 12:18 = 16:___
To find the missing value in the equivalent ratio 12:18 = 16:___, you can use cross-multiplication.
First, you multiply the first term of the first ratio by the second term of the second ratio, and then you set it equal to the product of the second term of the first ratio and the missing value in the second ratio.
So, you get:
12 x ___ = 18 x 16
To solve for the missing value, you can divide both sides of the equation by 12:
___ = (18 x 16)/12
Simplifying the right-hand side, you get:
___ = 24
Therefore, the missing value in the equivalent ratio 12:18 = 16:___ is 24
Answer:24

Life in the neighborhood depicted in the film "Los Olvidados" is characterized by challenging economic and social conditions.
How do the economic and social conditions shape life in the neighborhood?The neighborhood in "Los Olvidados" is portrayed as a poverty-stricken area where the residents struggle to make ends meet. The film explores the lives of marginalized individuals most particularly young boys, who are caught in a cycle of poverty, violence, and neglect.
The economic conditions in the neighborhood are harsh, with limited opportunities for employment and a lack of access to basic necessities. As a result, the residents are often forced into criminal activities to survive leading to a high level of violence and crime within the community.
Moreover, the social conditions exacerbate the challenges faced by the neighborhood. There is a sense of abandonment and neglect from the government and wider society with little support or resources available to address the issues faced by the residents.

he accompanying histogram shows the life expectancies at birth for 190 countries as collected by an international health agency.
a) Which would you expect to be larger: the median or the mean? Explain briefly.
b) Which would you report: the median or the mean? Explain briefly.
a) The median would be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean.
b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers.
a) The median is expected to be larger than the mean because the life expectancy of some countries may be much lower than the others, thus affecting the mean. The mean is calculated by adding all the values together and dividing by the number of values, and if there are any values that are much lower or higher than the rest, this will affect the mean significantly. The median, however, is the midpoint of the values, so outliers have less of an influence on it.
b) The median should be reported as it is a better measure of central tendency, as it is not affected by outliers. The median is the midpoint of the values, which means that if there are any values that are much lower or higher than the rest, it will not affect the median as much as it does the mean. This makes the median more accurate in representing the life expectancy of countries, as it is not skewed by outliers. Furthermore, the median is generally more reliable when dealing with skewed distributions, which is often the case with life expectancy data.

what is plotting data?The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables. Diagrams created by hand or on a computer are also acceptable. Move 2 units to the right after starting at the origin before going 3 units up. The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points. The pink dot with the letter P thus stands for 2.3. Before creating a line chart, you need first generate a number line for each value in your data collection. Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

First, let's find the slope with y2 - y1/x2 - x1
Plug in using (-1, 5) and (-4, 11)
11 - 5/-4 + 1 = 6/-3 (simplify)
-2 is the slope
Now plug in (-7, 17) in the equation to get b or the y-intercept)
y = mx + b
17 = -2(-7) + b
17 = 14 + b (subtract 14 on both sides)
3 = b

The continuous random variable V has a probability density function given by: 6 f(v) = for 3 ≤ ≤7,0 otherwise. 24 What is the expected value of V? Number
The expected value of the continuous random variable V is 5. The expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.
To calculate the expected value of a continuous random variable V with a given probability density function (PDF), we integrate the product of V and the PDF over its entire range.
The PDF of V is defined as:
f(v) = 6/24 = 0.25 for 3 ≤ v ≤ 7, and 0 otherwise.
The expected value of V, denoted as E(V), can be calculated as:
E(V) = ∫v * f(v) dv
To find the expected value, we integrate v * f(v) over the range where the PDF is non-zero, which is 3 to 7.
E(V) = ∫v * (0.25) dv, with the limits of integration from 3 to 7.
E(V) = (0.25) * ∫v dv, with the limits of integration from 3 to 7.
E(V) = (0.25) * [(v^2) / 2] evaluated from 3 to 7.
E(V) = (0.25) * [(7^2 / 2) - (3^2 / 2)].
E(V) = (0.25) * [(49 / 2) - (9 / 2)].
E(V) = (0.25) * (40 / 2).
E(V) = (0.25) * 20.
E(V) = 5.
Therefore, the expected value of the continuous random variable V is 5.
The expected value represents the average value or mean of the random variable V. It is the weighted average of all possible values of V, with each value weighted by its corresponding probability. In this case, the expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.
