Consider the modified Harrod-Domar Growth model: c(g+δ)=(s
π
−s
W
)(
Y
π
)+s
W
As a planner, you're targeting a 4\% growth rate. If depreciation (delta) =0.03, capitaloutput ratio (c)=3,pi/Y=0.5, and savings out of capital income, s(pi)=25%. At what rate should the wage earners and rural households save? (Note: Write in \%, no decimal)
The rate at which the wage earners and rural households should save is 21%.
Given that:
Depreciation (δ) = 0.03
Capital output ratio (c) = 3
Profit share of income (π/Y) = 0.5
Savings out of capital income (sπ) = 25% = 0.25
We know that the modified Harrod-Domar growth model is given as:
c(g+δ) = (sπ - sW)(Yπ) + sW
We can rearrange the above equation to find the value of savings out of wage income as follows:
sW = c(g+δ - sπ(Yπ))/ (sπ - π/Y)
Plugging in the given values:
sW = 3(0.04 + 0.03 - 0.25(0.5))/ (0.25 - 0.5)
On solving the above equation, we get:
sW = 0.21 or 21%
Hence, the rate at which the wage earners and rural households should save is 21%. Therefore, the required answer is 21%.

You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?
Investing $500 into account that collects 1% interest each month and add an $50 each week for 5 months, your balance will be $1,275.00.
To start, you invested $500 into an account that collects 1% interest each month. This means that after the first month, your balance will have grown by 1% of $500, or $5.00. So at the end of the first month, your balance will be $505.00.
Next, you add an additional $50 each week. This means that after the first week, your balance will have grown by $50, bringing your balance to $555.00. After the second week, your balance will have grown by another $50, bringing it to $605.00.
We can continue this pattern for 5 months, or 20 weeks. So after the third week, your balance will be $655.00, and after the fourth week, your balance will be $705.00.
Continuing this pattern for the next 16 weeks, your balance will continue to grow with the additional $50 each week and the 1% interest each month. At the end of the 5 months, your balance will be approximately $1,275.00.

while roughly 40 percent of children are born to unmarried mothers, this may not be an accurate representation of the situation. a more accurate representation of the situation may be gained by looking at the percentage of american children under 18 living with one parent (single-parent families). what is that percentage?
According to given data on unmarried mothers as of 2021, around 25% of American children under 18 are living with a single parent.
The percentage of children born to unmarried mothers does not necessarily indicate the percentage of children living with a single parent, as some unmarried parents may choose to live together and raise their children as a family. Therefore, looking at the percentage of children living with a single parent provides a more accurate representation of the situation.
According to the US Census Bureau's 2020 report, around 25% of American children under 18 live with a single parent. This percentage has increased over the years, with 22% of children living with a single parent in 2000 and 19% in 1980.

36 · x = 9 · 6

A closet contains 6 pairs of shoes. If 4 shoes are chosen at random, what is the probability that there will be(a) no complete pair,(b) exactly one complete pair among them?
a.) The probability that there will be no complete pair is: 2/11
b.) The probability that there will be exactly one complete pair is: 32/11
To solve this problem, we can use the formula for probability:
P(A) = number of favorable outcomes / number of possible outcomes
where A is the event whose probability we want to calculate.
(a) To find the probability that there will be no complete pair, we need to count the number of ways to choose 4 shoes out of the 12 shoes in the closet such that no pair is complete. We can do this by first choosing 2 shoes from each pair, which gives us 6 pairs of shoes to choose from. Then we need to choose 4 shoes out of these 6 pairs without choosing any complete pair. There are 6C4 ways to do this.
Finally, there are 2 choices for each shoe (left or right), so there are 2^4 = 16 ways to choose which shoe from each pair to include. Therefore, the number of favorable outcomes is 6C4 x 16 = 90.
The number of possible outcomes is simply the number of ways to choose any 4 shoes out of the 12 shoes, which is 12C4 = 495.
So the probability that there will be no complete pair is:
P(A) = 90 / 495 = 6 / 33 = 2 / 11.
(b) To find the probability that there will be exactly one complete pair, we need to count the number of ways to choose 4 shoes out of the 12 shoes in the closet such that one pair is complete and the other 2 shoes are not part of any pair. We can do this by first choosing 1 of the 6 pairs, which gives us 2 shoes that must be included. Then we need to choose 2 shoes out of the remaining 10 shoes, which is 10C2.
Finally, there are 2 choices for each of the 2 remaining shoes, so there are 2^2 = 4 ways to choose which shoe from each pair to include. Therefore, the number of favorable outcomes is 6 x 10C2 x 4 = 1440.
The number of possible outcomes is still 12C4 = 495.
So the probability that there will be exactly one complete pair is:
P(A) = 1440 / 495 = 64 / 22 = 32 / 11.

Step-by-step explanation:
A solid rectangular right prism is 12 inches long, 6 inches high, and 6 inches deep. At one square base of the prism, a 3 inch high square pyramid is cut from the prism. At the opposite square base of the prism, a square pyramid measuring 4 inches high is added. The bases of the pyramids are the same size as the square bases of the rectangular prism.
What is the volume of the composite figure?
Enter your answer in the box.
By answering the presented question, we may conclude that Therefore, the volume of the composite prism figure is 492 cubic inches.
what is prism?A prism is an n-sided quadrilateral polyhedron with an n-sided quadrilateral base, a second base that is a relocated duplicate of the first base, and n extra heads (necessarily all parallelograms), generally with two connecting the corresponding sides of the base. Any cross sections that appear parallel to the base are translations. A prism is a solid, three-dimensional object having numerous faces. It has identical cross-sections, horizontal flanks, and bases. A prism's faces are parallelograms or quadrilaterals with no bases. A prism is a refracting object that is homogenous, solid, and transparent, and it is surrounded by planes that are just slightly inclined to one another. A prism typically has two triangular heads and two parallel rectangular sides.
The volume of the rectangular prism is:
V1 = length x width x height
\(V1 = 12 x 6 x 6\)
V1 = 432 cubic inches
\(V2 = (1/3) x base area x height\\V2 = (1/3) x 6^2 x 3\)
V2 = 36 cubic inches
A = length x width
A = 12 x 6
A = 72 square inches
Now we can find the volume of the second pyramid:
\(V3 = (1/3) x base area x height\\V3 = (1/3) x 72 x 4\)
V3 = 96 cubic inches
Vcomposite = V1 - V2 + V3
Vcomposite = 432 - 36 + 96
Vcomposite = 492 cubic inches
Therefore, the volume of the composite figure is 492 cubic inches.

Determine the resulting vector when a=(-4, 6) is rotated 60° clockwise and increased in size by a multiple of 2
The resulting vector after rotating a=(-4, 6) by 60° clockwise and increasing its size by a multiple of 2 is approximately (3.46, 17.32).
To determine the resulting vector when vector a=(-4, 6) is rotated 60° clockwise and increased in size by a multiple of 2, follow these steps:
1. Rotate the vector 60° clockwise:
To do this, use the rotation matrix formula: R(θ) * (x, y) = (x * cos(θ) + y * sin(θ), -x * sin(θ) + y * cos(θ))
Here, θ = -60° (clockwise rotation is negative), and convert it to radians: θ = -π/3.
R(-π/3) * (-4, 6) ≈ (1.73, 8.66)
2. Increase the size by a multiple of 2:
Multiply the rotated vector's components by 2:

What is the radius of a circle whose endpoints of a diameter are A(-4, 14) and B (2,8)
9514 1404 393
Answer:
3√2
Step-by-step explanation:
The length of the diameter is given by the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-4))² +(8 -14)²) = √(36 +36) = 6√2
The radius is half the diameter, so the radius of your circle is 3√2.
S part of a statistic project, a math class weighed all the children who were willing to participate as shown below.
How many children weighed less than 50 pounds?
Answer:
18 children weighed less than 50 pounds.
Step-by-step explanation:
Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.
For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.
8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.
