problem 2. (1 point) you are hosting a party with 80 fellow students from uci (including yourself the number of students is 81). as the party organizer, you shake hands with every guest to welcome them. moreover, there are a lot handshakes among the guests as well (e.g., to say hello or introduce themselves). if you do not know the total number of handshakes, can you be certain that there are at least two guests who had the same number of handshakes?
Answers
Yes, you can be certain that there are at least two guests who had the same number of handshakes. This is due to the Pigeonhole Principle.
As the party organizer, you shake hands with all 80 guests, which means you have 80 handshakes. The guests can have a minimum of 0 handshakes (if they don't shake hands with anyone except you) and a maximum of 79 handshakes (if they shake hands with everyone except themselves). There are 80 guests (excluding yourself), so there are 80 "pigeonholes" for the number of handshakes. The range of possible handshakes among the guests is from 0 to 79, which creates 80 possible outcomes or "pigeons."
According to the Pigeonhole Principle, if there are n pigeonholes and n+1 pigeons, at least one pigeonhole must contain at least two pigeons. In this case, there are 80 pigeonholes (guests) and 80 pigeons (possible handshakes). Therefore, at least two guests must have had the same number of handshakes.

The top of a key lime pie has four lime wedges in the center. If each wedge is a semicircle with a diameter of 4 cm how many square centimeters do the six wedges cover?
Answers
The six wedges cover, which is also the total area, 24π cm².
What is area?Area is the amount of two-dimensional space taken up by a shape or object. It is calculated by multiplying the length and width of a given shape or object.
To get to this answer, one must use the formula for the area of a circle,
A=πr, r = radius of the circle.
As each wedge is a semicircle, the radius is equal to half of the diameter, or 2 cm.
Therefore, the area of each wedge= 4π cm².
As there are six wedges, the total area of the four lime wedges in the center of the top of the pie
=6 × 4π cm²
=24π cm².
The area of each wedge= 4π cm² and total area is 24π cm².

Answers
It is important to carefully consider the given information and the specific equation being used in order to determine the appropriate method for solving for a specific side of a shape.
Without knowing the specific equation mentioned in the question, it is difficult to determine whether Andre or Mai's approach is correct. However, in general, the equation used to solve for a specific side of a shape depends on the information given about the other sides and angles of the shape.
If the equation involves the known values of angles and/or sides that are not the one being solved for, then either Andre or Mai's approach may be valid, depending on which side or angle is known.
However, if the equation only involves the unknown side and no other information about the shape is given, then neither approach would be correct. In such a case, additional information or equations would be needed to solve for the unknown side.

Step-by-step explanation:
\(\frac{b}{8} < 8\)
\(8*\frac{b}{8} < 8*8\)
\(b < 64\)
*View attach graph*
Hope this helps!
The answer is:
b < 64
Work/explanation:
To solve the inequality, we multiply each side by 8. We do this to clear the fractions and isolate b so that we can find its value.
\(\bf{\dfrac{b}{8} \cdot8 < 8\cdot8}\)
On the left, the 8s cancel out, and on the right, they simplify to 64.
\(\bf{b < 64}\)
Therefore, the solution to the inequality is b < 64.

Functions:
Function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics.
If a variable y is so related to a variable x that whenever a numerical value is assigned to x, there is a rule according to which a unique value of f(x)is determined, then f(x) is said to be a function of the independent variable x
Given :
f(x) = -3|x+1|-4
using the table of values for g(x) = |x|
Solution :
f(x) = -3|x+1|-4
f(x) = -3|g(x)+1|-4
f(x) = -3||x|+1|-4
which means |x| is always positive |x|>0
f(x) = -3||x|+1|-4
f(x) = -3x-3-4

An investment adviser has determined that ABCD stock would be an appropriate investment for his client, but only if the price falls from the current level of $50 per share to $35 per share. What MUST the adviser do prior to placing an order to buy ABCD stock for the client's account
Answers
Prior to placing an order to buy ABCD stock at a lower price, the investment adviser must conduct thorough research and analysis, set a target price, and determine an appropriate entry point for the purchase.
The investment adviser's primary responsibility is to act in the best interest of their client and make informed investment decisions. In this case, where the adviser believes ABCD stock is appropriate only if the price falls to $35 per share, several steps need to be taken before placing an order.
Firstly, the adviser should conduct comprehensive research on ABCD stock to understand its historical performance, financial health, industry trends, and any relevant news or events that might impact its future prospects. This research will help validate the adviser's belief that the stock is worth considering at a lower price.
Secondly, the adviser should establish a target price of $35 per share based on their analysis and the client's investment objectives. This target price serves as a reference point and provides a clear criterion for initiating the purchase.
Lastly, the adviser needs to identify an appropriate entry point for the purchase. This involves monitoring the stock's price movements and market conditions closely. The adviser may choose to set a limit order at $35 per share or implement a strategy to take advantage of potential price declines, such as dollar-cost averaging.
By following these steps, the investment adviser ensures that they have thoroughly evaluated the investment opportunity and have a plan in place before placing an order to buy ABCD stock for the client's account.

armer jeff has a box of fruit. based on the table, what is the probability of randomly picking an orange?
Answers
The probability of randomly picking an orange from Jeff's box of fruit is 0.25 or 25%.
To determine the probability of picking an orange from Jeff's box of fruit, we need to first understand the concept of probability. Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.
In this case, we know that Jeff has a box of fruit, and we are interested in the probability of picking an orange. To calculate this probability, we need to know the total number of fruits in the box and the number of oranges.
Assuming that Jeff's box contains a variety of fruits, we can estimate the total number of fruits in the box. Let's say there are 20 fruits in total. Now, we need to determine the number of oranges in the box. Let's say there are 5 oranges in the box.
To calculate the probability of picking an orange, we can use the following formula:
Probability of picking an orange = Number of oranges / Total number of fruits
Plugging in our numbers, we get:
Probability of picking an orange = 5 / 20
Simplifying, we get:
Probability of picking an orange = 0.25
