12 I just solved this one!
Answer:
1.641× 10^-3 pounds/ cubic inch
Step-by-step explanation:
Density= mass / volume
Mass of the material= 9 kilograms
Volume= 7 cubic feet
Density= 9/7= 1.286 kg/ ft^3
Density= 1.286 kg/ ft^3
To Convert to pounds per inch
1 kg/ ft^3 = 0.00128 pound / cubic inch
1.286 kg/ ft^3 = X pounds/ cubic inch
X=( 1.286 × 0.00128)
= 0.0016407087 pounds/ cubic inch
= 1.641× 10^-3 pounds/ cubic inch
Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch
2 eggs are needed because if you need 4 to make 2 batches, you have to divide 4 by 2.
We want to find the median for the given density curve.
The value of the median is 4.5. ({3+6)/2}
Let's see how to solve this.
First, for a regular set {x₁, ..., xₙ} we define the median as the middle value.
The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.
Here, we have a constant density curve that goes from 3 to 6.
Because it is constant, the median will just be equal to the mean, thus the median is the average between the two extreme values.
Remember that the average between two numbers a and b is given by:(a + b)/2
So we get: m = (6 + 3)/2 = 4.5
So we can conclude that the value of the median is 4.5, so the correct option is the second one, counting from the top.

Answer:
You will need 400 meters of cord.
Step-by-step explanation:
Since it's a square, we know the perimeter of the piece of land is 20 times 4, or 80. Because it is going around it 5 times, we just multiply 80 by 5 to get 400. You will need 400 meters of cord.
