Alpa must take out at least 19 T-shirts from the bag to be absolutely sure of having at least two T-shirts among them that differ only by size or only by color.
What is the Pigeonhole Principle?
The Pigeonhole Principle is a fundamental concept in combinatorics, which is a branch of mathematics that deals with counting and analyzing the properties of sets of objects. The principle states that if there are more pigeons than pigeonholes, then at least one pigeonhole must contain more than one pigeon.
We can solve this problem using the Pigeonhole Principle, which states that if n+1 objects are distributed among n boxes, then there is at least one box that contains two or more objects.
In this case, we want to be sure that we have at least two T-shirts that differ only by size or only by color.
So we need to find the minimum number of T-shirts that we must take out of the bag to guarantee this.
Let's consider the worst-case scenario, where we take out all the T-shirts that are of one size or one color.
If we take out all 18 small red T-shirts, we still need to take out at least one more T-shirt to be sure that we have at least two T-shirts that differ only by size or only by color (since we could still get a small black T-shirt).
Similarly, if we take out all 19 small black T-shirts, we still need to take out at least one more T-shirt to be sure that we have at least two T-shirts that differ only by size or only by color.
If we take out all 13 large black T-shirts, we still need to take out at least one more T-shirt to be sure that we have at least two T-shirts that differ only by size or only by color.
If we take out all 15 large red T-shirts, we still need to take out at least one more T-shirt to be sure that we have at least two T-shirts that differ only by size or only by color.
So we need to take out at least 19 T-shirts to be sure that we have at least two T-shirts that differ only by size or only by color. (We add one to the largest number of T-shirts of one color or size.)
Therefore, Alpa must take out at least 19 T-shirts from the bag to be absolutely sure of having at least two T-shirts among them that differ only by size or only by color.

any help? i dont seem to understand which radius of circle is.
First of all, radius is half the diameter. Radius is from the center-most point of a circle straight to the edge.
Answer:
The area of the whole object is 1,237.68 m^2 (meters squared).
Step-by-step explanation:
The circles are equal to:
π * d = a
3.14 * 12 = a
37.68 = a.
Now, since the circles are half in the rectangle, it would be easier to calculate the rectangle using these halves, so the total of the half-circles outside the rectangle is equivalent to a whole circle, or 37.68. Now, let's calculate the rectangle:
20 * (30 * 2) = a
20 * 60 = a
1200 = a.
The whole area is equivalent to the area of the two half-circles and the area of the rectangle:
37.68 + 1200 = a
1237.68 = a
A diagram shows a garden bed. The area of the garden bed is 21ft to the power of 2. What is the Height of the garden bed. Need help ASAP
Answer: 1.75
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Since the garden bed looks like the shape of a trapezoid the equation to find the area of a trapezoid is A = 1/2h (base 1 + base 2)
The area is already given so you can just plug it in. Also you can plug in the bases.
21 = 1/2h (3 + 4)
21 = 1/2h (7) rewrite
21 = 1/2(7)h
21 = 3.5h Divide both sides by 3.5

Cuantos subconjuntos tiene A={a, r, i, t, m, e, t, i, c, a}
The number of subsets that the set has are 128 subsets.
How to find the number of subsets?First, let's remove the duplicates from the set A. The distinct elements in set A are:
A = {a, r, i, t, m, e, c}
Now, we can find the number of subsets. For each element in the set, we have two choices: either it is included in the subset, or it is not. Therefore, there are 2^n subsets for a set with n distinct elements.
In our case, n = 7, so there are 2^7 = 128 subsets for the given set A.

When you multiply an inequality by a positive number, the direction of the inequality does not change. So if 4 < 7, then:
what is inequality?
Inequality is a mathematical statement that describes a relationship between two values or expressions that are not equal. In an inequality, we use the symbols "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to) to indicate the relationship between the values or expressions.
For example, "x < 5" is an inequality that means "x is less than 5", and "y ≥ 10" is an inequality that means "y is greater than or equal to 10". Inequalities are often used in algebra and other branches of mathematics to express relationships between variables or to solve problems.
Multiplying both sides by

Suppose you roll a special 11-sided die. What is the probability that the number rolled is a "1" OR a "2"?
The probability of rolling a "1" OR a "2" on an 11-sided die is 2/11, or approximately 0.1818.
What is probability?Probability is a way to gauge how likely or unlikely something is to happen. Usually, it is stated as a number between 0 and 1, where 0 denotes that an event is impossible and 1 denotes that it is certain to happen.
According to question:The probability of rolling a "1" or a "2" on an 11-sided die can be calculated by adding the probabilities of rolling a "1" and rolling a "2".
Assuming the die is fair (i.e., each face has an equal chance of landing face up), the probability of rolling any particular number is 1/11. Therefore, the probability of rolling a "1" is 1/11, and the probability of rolling a "2" is also 1/11.
To find the probability of rolling a "1" OR a "2", we add the probabilities:
P(rolling a "1" OR a "2") = P(rolling a "1") + P(rolling a "2")
P(rolling a "1" OR a "2") = 1/11 + 1/11
P(rolling a "1" OR a "2") = 2/11
Therefore, the probability of rolling a "1" OR a "2" on an 11-sided die is 2/11, or approximately 0.1818 (rounded to four decimal places).

Consider the information below for Postman Builders Inc. Suppose that the expected inflation rate and thus the inflation premium increases by 2.0 percentage points, and Postman acquires risky assets that increase its beta by the indicated percentage. What is the firm's new required rate of return? Beta 1.5, Required Return 10.2, RPm 6%, Percentage increase in beta 65
Therefore, Postman Builders Inc’s new required rate of return is 23.7%1.
SET A RATE?Rate might signify two different things. As a noun, it denotes an amount, frequency, or measure that is typically compared to another quantity or measure. Or, it can be used as a verb to indicate "assign a standard or value to" using a specific scale.
Postman Builders Inc. has a necessary return of 10.2% and a beta of 1.5, according to the information given.
We may get the new necessary rate of return as follows if Postman purchases risky assets that increase its beta by 65% and the predicted inflation rate and inflation premium increase by 2 percentage points.
New Required Rate of Return
= Risk-free rate + Beta * (Expected Market Return - Risk-free rate)
= 2% + (1.5 * (6% + 2% + (65% * 6%))) = 23.7%
New Required Rate of Return equals 8% plus 2.47 x (-2%) to 3.85%.

What is an acute triangle?An acute triangle is a type of triangle where all three angles are acute angles, meaning they are less than 90 degrees. In other words, an acute triangle is a triangle with all three angles being sharp or narrow.
The best representation of the possible range of values for the third side, s, can be determined using the Triangle Inequality Theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, we have two sides measuring 8 cm and 10 cm. Let's call the third side "s". Using the Triangle Inequality Theorem, we can write:
8 + 10 > s
18 > s and
8 + s > 10
s > 2
and
10 + s > 8
s > -2 (since a length cannot be negative)

Therefore, the expected value of the event P(2k) for 2 ≤ k ≤ 6, given the event E, is 96/1 or simply 96.
What is probability?Probability theory is widely used in many fields, including mathematics, statistics, physics, engineering, economics, and social sciences. It provides a framework for analyzing and understanding uncertain events and making predictions based on available information. Probability theory is also used in decision-making, risk management, and game theory, among other applications.
Here,
We can start by calculating the probability of each event in the sample space:
P(1) = 1/32
P(4) = 1/8
P(8) = 1/4
P(16) = 1/2
P(32) = 1
P(64) = 1
Next, we can calculate the probability of the event E by summing the probabilities of the individual outcomes in E:
P(E) = P(1) + P(8) + P(32) + P(64)
= 1/32 + 1/4 + 1 + 1
= 33/32
Now, we can calculate the expected value of the event P(2k) for 2 ≤ k ≤ 6:
E[P(2k)] = Σ[2 ≤ k ≤ 6] P(2k) * ΘS(2k)
= P(4)*ΘS(4) + P(8)*ΘS(8) + P(16)*ΘS(16) + P(32)*ΘS(32) + P(64)*ΘS(64)
= (1/8)*4 + (1/4)*8 + (1/2)*16 + (1)*32 + (1)*64
= 4/8 + 8/4 + 16/2 + 32 + 64
= 1/2 + 2 + 8 + 32 + 64
= 106.5
Therefore, the expected value of the event P(2k) for 2 ≤ k ≤ 6, given the event E, is 106.5. However, since the event E has a probability greater than 1, this result does not make sense. So, we need to normalize the probabilities of the events by dividing them by P(E) to obtain the correct expected value:
P'(1) = P(1)/P(E) = (1/32)/(33/32) = 1/33
P'(8) = P(8)/P(E) = (1/4)/(33/32) = 8/33
P'(32) = P(32)/P(E) = 1/(33/32) = 32/33
P'(64) = P(64)/P(E) = 1/(33/32) = 32/33
Now, we can calculate the normalized expected value:
E[P(2k)] = Σ[2 ≤ k ≤ 6] P'(2k) * ΘS(2k)
= P'(8)*ΘS(8) + P'(32)*ΘS(32) + P'(64)*ΘS(64)
=(8/33)*8 + (32/33)*32 + (32/33)*64
= (64/33) + (1024/33) + (2048/33)

The function = 50 − 1.6 can be used to determine the amount, in fluid ounces, of laundry detergent remaining after x loads of laundry have been done. What is the rate of change amount of laundry in fluid ounces with respect to the number of loads of laundry that have been done?
The rate of change of the amount of laundry with respect to the number of loads is a constant value of -1.6 fluid ounces per load.
What is linear equation?Any equation that has terms that are either constants or the product of a constant and a variable of the first degree (exponent 1) is said to be linear. In other words, the equation's greatest degree for any variable is 1. One way to express a linear equation is as follows:
ax + b = 0
If an is not equal to zero, a and b are constants, and x is the variable. This is how a linear equation is typically expressed.
The given function is f(x) = 50 - 1.6x.
Now, the rate of change is the slope of the equation.
Comparing the equation with that of the linear equation y = mx + c we see that the slope is -1.6.
Hence, the rate of change of the amount of laundry with respect to the number of loads is a constant value of -1.6 fluid ounces per load.

What amount of a 80% acid solution must be mixed with a 55% solution to produce 600 mL of a 60% solution?
Answer:The amount of a 80% acid solution that must be mixed with a 55% solution to produce 600 mL of a 60% solution can be calculated using a simple algebraic equation. Let x represent the amount of the 80% acid solution in mL that needs to be mixed with the 55% solution.
The equation can be set up as follows:
0.80x + 0.55(600 - x) = 0.60(600)
Step-by-step explanation: The left-hand side of the equation represents the total amount of acid in the mixture. The first term, 0.80x, represents the amount of acid from the 80% solution, and the second term, 0.55(600 - x), represents the amount of acid from the 55% solution. The right-hand side of the equation represents the total amount of acid in the final 60% solution, which is 60% of 600 mL.
By solving this equation for x, we can determine the amount of the 80% acid solution that needs to be mixed with the 55% solution. Once we have the value of x, we can then calculate the amount of the 55% solution by subtracting x from 600 mL.

Let x=amount of 80% solution needed
Then 600-x=amount of 30% solution needed
Now we know that the pure acid in the 80% solution (0.80x) plus the amount of pure acid in the 30% solution ((0.30)(600-x)) has to equal the amount of pure acid in the final mixture(0.40*600), so our equation to solve is:
0.80x+0.30(600-x)=0.40*600 get rid of parens
0.80x+180-0.30x=240 subtract 180 from each side
0.80x+180-180-0.30x=240-180 collect like terms
0.50x=60 divide each side by 0.50
x=120 ml---------------------amount of 80% solution needed
600-x=600-120=480 ml---------------amount of 30% solution needed
