According to the information, the least number of committees that need to be formed to meet all of the conditions is 8.
How to calculate the least number of committees that need to be formed to meet all of the conditions?To minimize the number of committees, we can try to use each student in as many committees as possible. Since each student must be in exactly 2 committees, and there are 12 students, we need a total of 24 "student committee slots".
Now we need to figure out how to assign the students to committees so that no two committees have more than one student in common. One way to do this is to use a "round-robin" approach:
Assign the first student to committees 1, 2, and 3.
For the next student, assign them to committees 1, 4, and 5.
For the third student, assign them to committees 2, 4, and 6.
Continue in this way, cycling through the remaining students and assigning them to three committees at a time, making sure to avoid any duplicates.
After assigning all 12 students to committees in this way, we will have a total of 8 committees. We can check that each committee contains exactly 3 students, and that no two committees have more than one student in common.

A rectangular prism measures cm by 12 cm by cm. Calculate the number of cubes with edge length cm that fit in this prism. What is the volume of the prism in ? Show your reasoning. If you are stuck, think about how many cubes with -cm edge lengths fit into .
By calculating the volume of both figures, we will see that 11,160 cubes can be fit in the prism.
Now, So we start with a rectangular prism that measures (7 + 1/2)cm by 12cm by (15 + 1/2) cm.
Hence, The volume is just the product of these 3 values,
so we get:
V = (7 + 1/2)cm × 12cm × (15 + 1/2)cm
V = 1,395 cm³
Now, a cube with an edge length of 1/2 cm has a volume of:
V' = (1/2cm)³
V' = 0.125 cm³
To see how many of the small cubes enter in the prism, we just need to take the quotient between these two volumes, this is:
V/V' = ( 1,395 cm³)/(0.125 cm³) = 11,160
This means that, 11,160 of the cubes can be fit in the prism.

Given the triangle ABC at points A = ( 2, 2 ) B = ( 4, 5 ) C = ( 6, 3 ), and if the triangle is first reflected over the y axis, and then over the x axis, find the new point A''.
To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:
1. Reflect A over the y-axis to get A': (-2, 2)
2. Reflect A' over the x-axis to get A'': (-2, -2)
Therefore, the new point A'' is (-2, -2).

The fox population in a certain region has a continuous growth rate of 4 percent per year. It is estimated that the population in the year 2000 was 21400.
(a) Find a function that models the population
t
years after 2000 (
t
=
0
for 2000
Answer:
Step-by-step explanation:
Let P(t) be the fox population t years after 2000. We know that the population has a continuous growth rate of 4% per year, which means that the population increases by a factor of 1.04 each year. Therefore, we can model the population as:
P(t) = 21400 * 1.04^t
Here, we start with the population in the year 2000 (21400) and multiply it by 1.04 raised to the power of the number of years after 2000 (t).
For example, if we want to find the population in the year 2015 (15 years after 2000), we can plug t = 15 into the equation:
P(15) = 21400 * 1.04^15
= 21400 * 1.618
= 34694.8
Therefore, we can expect the fox population to be approximately 34,695 in the year 2015.

A rectangular field is four times as long as it is wideIf the perimeter of the field is 300yards, what are the field's dimensions?
Answer:
Length = 120 yards, width = 30 yards.
Step-by-step explanation:
Lets use [tex]l[/tex] for length and [tex]w[/tex] for width.
The perimeter of a rectangular field is [tex]2l + 2w[/tex]. We can construct the following equations:
[tex]4w = l[/tex].
[tex]2l + 2w = 300.[/tex]
If we plug [tex]4w[/tex] in for [tex]l[/tex] into the second equation, we get:
[tex]2w + 2(4w) = 300.[/tex]
[tex]2w+8w = 300.[/tex]
[tex]10w = 300.[/tex]
[tex]w= 30.[/tex]
Plug 30 in for [tex]w[/tex] into the first equation.
[tex]l = 4*30 = 120.[/tex]
Length = 120 yards, width = 30 yards.

Each question can be answered either true or false, giving two possible choices for each of the 8 questions.
Therefore, the total number of ways to answer the questions is the product of the number of choices for each question, which is:
2⁸ = 256If A is the set of numbers that are multiples of 8, B is the set of multiples of 4, and C is the set of multiples of 2, which of the following is the set of integers that will be in A but not B and C?
The set of integers that will be in A but not B and C will be 24, 32, 40,
How to explain the integerThe multiples of 8 comprise a set of {8, 16, 24, 32, 40, ...}, while the multiples of 4 correspond to {4, 8, 12, 16, 20, ...} and those of 2 are documented as {2, 4, 6, 8, 10, …}. The intersection of these two sets, B and C (B ∩ C = {4, 8, 12, 16, 20, ...}) remains unchanged.
It should be noted that to obtain the number of integers found in the multples of 8 that aren’t multiples either of 4 or 2, the intersection needs to be excluded from set A. This will yield {24, 32, 40, ...} - thus it is concluded that the integer set of multiples of 8, but not of 4 or 2, is {24, 32, 40, ...}

what is 2/5 x 1/8 please help
Answer:
1/20
Step-by-step explanation:
To multiply two fractions, you simply multiply their numerators (top numbers) together and multiply their denominators (bottom numbers) together.
So, for 2/5 x 1/8, we have:
(2/5) x (1/8) = (2 x 1) / (5 x 8) = 2/40 = 1/20
Therefore, 2/5 x 1/8 is equal to 1/20.
Multiplying the numerators and denominators directly is the most straightforward method to solve the multiplication of fractions. However, there is another method called cross-multiplication, which you can use to solve this problem as well.
To use cross-multiplication, you multiply the numerator of the first fraction by the denominator of the second fraction, and then multiply the denominator of the first fraction by the numerator of the second fraction.
Then, you simplify the resulting fraction.
So, for 2/5 x 1/8, we have:
(2/5) x (1/8) = (2 x 1) / (5 x 8)
Cross-multiplying, we get:
(2/5) x (1/8) = (2 x 1) / (5 x 8) = (2 x 1) / (5 x 8) = 2/40
Simplifying the fraction 2/40, we can divide both the numerator and denominator by 2, to get:
2/40 = 1/20
Therefore, using cross-multiplication, we get the same answer as before:
2/5 x 1/8 is equal to 1/20.
