Why are there 12 signs of the zodiac. how many people must be present for there to be at least a 50hance that two or more of them?
The answer to the given problem is 5
Probability is the degree to which an occurrence is likely to take place, as determined by the proportion of favorable examples to the total number of instances for which it is probable to have occurred.
Let's assume
1 - P(no one has the same sign) >= 0.5
P(two or more people have the same sign) = 1 - P(no one has the same sign)
= 1 - (12 / (12-n)) / 12^n
1-0.5=0.5 >= P (no one has the same sign) = 12/(12^n x (12-n))
0.5 >= 12 /(12^n x (12-n))
Solve for n.
n = 5
Hence the answer is 5

Faces:
Formula:
E = 2S is the equation that links the base's S number of sides to its F number of faces.
E = 2S
S is the number of sides on a base.
E equals the number of edges.
Triangle (1)
3 and S are the base side counts.
edges equal 6, hence the answer is E.
E = 2S
Table 2
Base has four sides, hence the response is S.
edge count = E (8 edges)
E = 2E
3rd Pentagon
S is equal to the five sides of the base.
The letter E is equivalent to 10 edges.
S = 2E
4) A hexagon
S is equal to the six sides of the base.
Edge count: 12 equals E.
E = 2S
Thus, it is shown that E = 2S.
The 30 sides of the pyramid foundation.
The answer is S since the base has 20 sides.
The number of edges is E = 2S = 20 x 2 = 40 edges.

7-(-4) is 4 units from 7 in the negative direction.
The number line keeps going both ways. You can include 6, 7, and so on, all the way up to the hundreds, thousands, and beyond, because the set of natural numbers only extends to the right.
A number line is a diagram that shows numerical values along a straight line that can be drawn either horizontally or vertically. It's simple for us to compare and compute basic arithmetic operations on numbers when they are written down on a number line. A number line's origin is typically thought to be zero (zero). There are only positive numbers to the right of zero and only negative numbers to the left of zero.
therefore,
7 - (-4)
= 7 + 4
= 11
when we simplify the expression we get the answer as 11 units
the result is that 11 units is 4 units away from 7 in a negative direction.

Caroline is the youngest of four siblings whose ages are consecutive odd integers. If the sum of their ages is 9696, find Caroline's age.
Answer:
2421 or 21
Step-by-step explanation:
Hello!
Consecutive odd integers are set of odd integers that come right after each other.
Let "C" be Caroline's age. Caroline's next older sibling would be C + 2, as odd integers come to every two numbers, and the next would be C + 4, and finally C + 6.
If we add up all the expressions, we should get 9696.
Solve for CC + C + 2 + C + 4 + C + 6 = 96964C + 12 = 96964C = 9684C = 2421The solution to this question does not seem reasonable. I assume that the correct sum of the age should be 96, given 9696.
If this is the case, then Caroline's age would be 21, using the same general logic.

You find 400 mg of a substance that has a half-life of 20 days. What is it's daily rate of decay? Round answers to four decimal places.
The daily rate of decay is approximately equal to 0.0347 days⁻¹.
What is the rate of decay of a substance?
According to the statement, we find that a substance is under a decay process, whose differential equation is introduced below:
dm(t) / dt = - k · m(t) (1)
Where:
m(t) - Current mass of a substance, in miligrams.k - Rate of decay, in 1 / day.The half-life of the substance is the time needed for a substance to decrease its mass by half. The rate of decay can be found in terms of half-life:
k = (㏑ 2) / t' (2)

Answer:
You will need 12.5 gallons of the 22% salt solution and 7.5 gallons of the 38% of the salt solution
Step-by-step explanation:
.22x + .38(20 -x) = .28(20) I want to clear the decimal, so I will multiple through by 100
100[.22x + .38(20-x)] = [.28(20)]100
22x + 38(20-x) = 28(20) Distribute the 38
22x + 760 -38x = 560 combine the x's
-16x + 720 = 560 Subtract 720 from both sides
-16x = -200 Divide both sides by -16

The equation of line is y = (-2/3)x + 5
Given the points:

(x₂, y₂) = ( 3, 3)
The slope-intercept form:
y = mx + b
Where, m is the slope and b is the y-intercept, that is (0, b)
The formula for slope:

By elimination, the solution of the system of equations, 4x + 2y = 4 and 6x + 2y = 8, is (2 , -2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in x and y, a variable should be eliminated by adding/subtracting the two equations.
Subtracting the two equations will eliminate the variable y.
6x + 2y = 8 (equation 2)
4x + 2y = 4 (equation 1)
2x + 0y = 4
x = 2
Substitute the value of x to any of the two equations and solve for y.
6x + 2y = 8 (equation 2)
6(2) +2y = 8
2y = 8 - 12
2y = -4
