Two sides of a triangle have lengths 3 cm and 8 cm respectively. The third side has a length of x cm, where x is an integer. Write down an inequality that must be satisfied by x
Answers
======================================================
Explanation:
Let's label the sides of the triangle a, b, and c.
Furthermore, let's have 'a' & b represent known sides and [tex]b \ge a[/tex] be the case. For a triangle to be possible, the missing side c must have these restrictions placed on it:
b-a < c < b+a
This inequality is valid because of a modification to the Triangle Inequality Theorem. I'll leave the proof to the reader.
-------
In this case we have a = 3 and b = 8 which lead to...
b-a < c < b+a
8-3 < x < 8+3
5 < x < 11
The third side is between 5 and 11, excluding both endpoints. We cannot have x = 5. Furthermore, we cannot have x = 11 either. If x were either of those endpoints, then we'd form a straight line rather than a triangle.
Having x be an integer leads to the roster set notation {6,7,8,9,10} to represent all possible values of x. For instance, we could have a triangle with side lengths 3, 8, and 6. I recommend getting slips of paper of these lengths to try it out yourself. Or you can use software such as GeoGebra to see why this works.

which type of graph would best display the following data? the number of hours a student spent studying for several tests and the student's grade on each test.
Answers
A scatter plot would best display the relationship between the number of hours a student spent studying for several tests and the student's grade on each test.
A scatter plot is a graph that displays the relationship between two continuous variables. In this case, the number of hours a student spent studying is the independent variable, which would be plotted on the x-axis. The student's grade on each test is the dependent variable, which would be plotted on the y-axis. Each data point would represent a single test, with the x-coordinate indicating the number of hours studied for that test and the y-coordinate indicating the grade received.
By using a scatter plot, you can easily identify any patterns or relationships between the number of hours studied and the student's grades on each test. It can also help to identify any outliers or anomalies in the data.

A spinner and a fair number cube are used in a game. The spinner has an equal chance of landing on 1 of 6 colors: red, purple, blue, green, white, or orange. The faces of the cube are labeled 1 through 6. What is the probability of a player spinning the color green and then rolling an even number?
Answers
The probability of spinning green and then rolling an even number is 1/36
What is Probability?Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
The probability of spinning green is 1/6 because there are 6 equally likely outcomes and 1 of them is green.
The probability of rolling an even number is 3/6 because there are 6 equally likely outcomes and 3 of them are even numbers (2, 4, and 6).
The probability of spinning green and then rolling an even number is the product of the probabilities of each event. To find this, we multiply the probability of spinning green (1/6) by the probability of rolling an even number (3/6):
(1/6) * (3/6) = 1/36
So, the probability of spinning green and then rolling an even number is 1/36.

The point A(2, 1) is a vertex of a square ABCD. M(5, 1) is the point of intersection of the
diagonals of the square. Find the coordinates of B, C and D. (Remember: The diagonals
of a square are equal in length and bisect each other at right angles.)
pls give serious answers!!
Answers
Answer:
Step-by-step explanation:
Since M is the point of intersection of the diagonals of the square, it is also the midpoint of both diagonals. This means that AM is equal to half the length of a side of the square and also bisects the angle formed by the two sides that it connects.
Let's call the length of a side of the square s. Then, the distance AM can be found using the Pythagorean theorem:
AM = sqrt((5 - 2)^2 + (1 - 1)^2) = sqrt(3^2 + 0^2) = sqrt(9) = 3
So, the length of a side of the square is 2 * AM = 2 * 3 = 6.
Next, we can use the length of a side and the coordinates of A to find the coordinates of B. Since AB is a side of the square and is 6 units long, we can find B by moving 6 units to the right of A:
B = (2 + 6, 1) = (8, 1)
We can also find the coordinates of C by moving 6 units up and 6 units to the left of A:
C = (2 - 6, 1 + 6) = (-4, 7)
Finally, we can find the coordinates of D by moving 6 units down and 6 units to the right of A:
D = (2 + 6, 1 - 6) = (8, -5)
So, the coordinates of the other vertices of the square are B = (8, 1), C = (-4, 7), and D = (8, -5).

Kofi says the circumference of a circle equals pi times the diameter. Skyla says that the circumference of a circle equals pi times the radius. Who do you agree with? Explain why? the picture is the real problem
Answers
I agree with Kofi that the circumference of a circle equals pi times the diameter. This is because the formula for the circumference of a circle is given by:
C = 2πr
Where C is the circumference, π is pi, and r is the radius of the circle. To find the diameter, we can double the radius, so we can write:
C = 2π(r) = π(2r) = πd
Where d is the diameter of the circle.
So, the formula for the circumference of a circle is indeed pi times the diameter, not just pi times the radius.

C. a third bond is worth $100 and grows in value by 4 percent each year, but the interest is applied continuously, at every moment. The value of this bond after years is given by 100-Order the bonds from slowest growing to fastest growing. Explain how you know
Answers
We can order the bonds from slowest-growing to fastest-growing as:
First bond: fixed growth rate of $50 per year
Third bond: growth rate of 4% per year, compounded continuously
Second bond: growth rate of 6% per year, compounded annually
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To order the bonds from slowest growing to fastest growing, we need to compare their growth rates.
The first bond grows at a fixed rate of $50 per year, regardless of how long it is held.
So its growth rate is constant and does not change with time.
The second bond is worth $500 and grows at a fixed annual rate of 6%, so its value after one year will be:
Value after one year
= $500 + 0.06 x $500
= $530
After two years, its value will be:
Value after two years.
= $530 + 0.06 x $530
= $561.80
We can see that the second bond's growth rate is increasing over time since the increase in value each year is calculated as a percentage of the new value.
The third bond is worth $100 and grows at an annual rate of 4% that is applied continuously.
The formula for the value of a continuously compounded bond after t years = $100 x e^(0.04t)
where e is the mathematical constant approximately equal to 2.718.
After one year,
The value of the third bond.
= $100 x e^(0.04 x 1) = $104.08
After two years,
Value after two years
= $100 x e^(0.04 x 2)
= $108.24
We can see that the growth rate of the third bond is also increasing over time because the interest is being compounded continuously.
Now,
We can order the bonds from slowest-growing to fastest-growing as:
First bond: fixed growth rate of $50 per year
Third bond: growth rate of 4% per year, compounded continuously
Second bond: growth rate of 6% per year, compounded annually

The number of calories consumed during a snack varies directly with the number of chocolates eaten. If Jodi eats 2 chocolates, she will consume 72 calories. How many calories will she consume if she eats 5 chocolates.
Answers
The required Jodi will consume 180 calories if she eats 5 chocolates.
What is directly Proportional?When two quantities are directly proportional, it indicates that if one increases by a specific percentage, the other also increases by the same percentage. As gas costs increase, the cost of food may as well as well.
According to question:We can use proportionality to solve this problem. Since the number of calories consumed varies directly with the number of chocolates eaten, we can write:
calories consumed / chocolates eaten = constant
Let's call this constant k. We can solve for k using the information given:
72 calories / 2 chocolates = k
k = 36 calories/chocolate
Now we can use this constant to find the number of calories Jodi will consume if she eats 5 chocolates:
calories consumed / chocolates eaten = k
calories consumed / 5 chocolates = 36 calories/chocolate
calories consumed = 5 chocolates * 36 calories/chocolate
calories consumed = 180 calories
Therefore, Jodi will consume 180 calories if she eats 5 chocolates.

What is meant by angle?An angle is a figure created by two rays or lines that have the same termination in plane geometry. The common terminal of the two rays—known as the vertex—is referred to as an angle's sides. Two lines converge at a common point to form an angle. They are expressed by the sign ° and are measured in degrees. Acute, right, obtuse, and reflex angles are four crucial types. There are 360° in a circle. It has completed two full rotations if you observe an angle of 720°.A polygon's total number of central angles equals 360 degrees.
As a result, the regular polygon's centre angle has a ratio of 360 to its number of sides. It may be expressed as,
[tex]$C_a=\frac{360}{n}[/tex]
Here, (n) denotes the regular polygon's number of sides.

Consider the following three events for college students:
A={A student is female.}
B={A student has financial aid.}
C={A student finishes his/her undergraduate degree in four years.}
Use symbols to describe the event that a college student is female or has financial aid.
Answers
The probability of a college student being either female or having financial aid can be expressed as P(A ∪ B) = P(A) + P(B).
What is Probability?
Probability is a mathematical concept used to measure the likelihood of a particular event occurring. It is a way of expressing the chance or possibility of an event happening, ranging from 0 (impossible) to 1 (certain).
In probability theory, an event is a subset of the possible outcomes of an experiment or a random process. Probability can be expressed in terms of fractions, percentages, or decimals.
The symbol for the event that a college student is female is A, as given in the statement. The symbol for the event that a college student has financial aid is B, as given in the statement.
So, A={A student is female} and B={A student has financial aid}.
These events are mutually exclusive because one does not necessarily affect the other. For example, a male student can have financial aid and a female student may not have financial aid. Hence, the occurrence of one event does not influence the occurrence of the other event.
Therefore, the probability of a college student being either female or having financial aid can be represented as the union of the events A and B. It can be denoted as P(A ∪ B) and is calculated as:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
Where P(A ∩ B) represents the probability of a student having both characteristics, i.e., being female and having financial aid.
However, as these events are mutually exclusive, P(A ∩ B) = 0. So the probability of a college student being either female or having financial aid is simply the sum of their individual probabilities:
P(A ∪ B) = P(A) + P(B) - 0
P(A ∪ B) = P(A) + P(B)
Hence, the probability of a college student being either female or having financial aid can be expressed as P(A ∪ B) = P(A) + P(B).

If you double the down payment what happens to the total cost and payment of the vehicle? What two ways can you lower your monthly payment?
Answers
Doubling the down payment reduces the total cost of the vehicle, and increasing the down payment or extending the loan term are two ways to lower the monthly payment.
Let's assume that you're planning to buy a car worth $20,000. The down payment is the initial amount you pay towards the purchase of the car, and it is usually expressed as a percentage of the total cost of the car. Let's assume that the down payment is 10% of the total cost, which means you have to pay $2,000 initially.
If you double the down payment from 10% to 20%, you will have to pay $4,000 initially. This means that the amount you borrow from the bank to buy the car will be reduced. As a result, the total cost of the vehicle will decrease because the interest on the loan will also decrease.
Now, let's move on to ways to lower your monthly payment.
Increase the down payment: As we discussed earlier, making a higher down payment reduces the loan amount, which, in turn, reduces the monthly payment. So, if you can increase the down payment, you can lower the monthly payment.
Increase the loan term: The loan term is the length of time you have to repay the loan. If you extend the loan term, the monthly payment will be lower. However, keep in mind that a longer loan term means you'll end up paying more interest over the life of the loan, which will increase the total cost of the vehicle.

a jury of 12 people is selected from a pool 30 people that includes 12 men and 18 women. what is the probability that the jury will be composed of 12 women
Answers
The probability of selecting a jury composed of 12 women from a pool of 30 people that includes 12 men and 18 women is extremely low, only 0.0657%.
The probability of an event happening is the measure of how likely that event is to occur.
In this case, we need to find the probability of selecting a jury of 12 women from a pool of 30 people. To calculate this probability, we can use the formula:
Probability = Number of favorable outcomes / Total number of outcomes
The total number of outcomes is the number of ways in which we can select 12 people from a pool of 30. We can calculate this number using the combination formula:
Total number of outcomes = C(30,12) = 30! / (12! * (30-12)!) = 28,238,760
Now, we need to calculate the number of favorable outcomes, which is the number of ways in which we can select 12 women from a pool of 18. We can calculate this number using the combination formula as well:
Number of favorable outcomes = C(18,12) = 18! / (12! * (18-12)!) = 18,564
Therefore, the probability of selecting a jury composed of 12 women is:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 18,564 / 28,238,760

Each gridline marker on the horizontal axis is π/4
The period of this function is the horizontal displacement at which the function starts to repeat itself
Looking at the function we see that the minimum value of the function is 1 and occurs first at -π/4 and then at 3π/4
So the period is 3π/4 - (-π/4) = 3π/4 + π/4 = (3/4 + 1/4)π = π
We could also double check this using another point of reference
let's take the peaks of the function
The first peak visible is at -3π/4 and the next peak at π/4
So the period = π/4 - (-3π/4) = π/4 + 3π/4 = π
