What is the area of a right triangle with side lengths 7,24, and 25?
Answers
Answer:
Area = 84 square unit
Step-by-step explanation:
Given the triangle is right angle triangle. According to Pythagoras theorem, the largest amount the sides is the hypotenuse. and the others are base and height respectively.
Therefore, hypotenuse = 25, base = 7, height = 24
\(Area \ of \ triangle = \frac{1}{2} \times \ base \times height\)
\(= \frac{1}{2} \times 7 \times 24 \\\\= 7 \times 12 \\\\= 84 \ square \ unit\)
Answer:
A = 84 units^ 2
Step-by-step explanation:
The longest side length is also the hypotenuse of this right triangle: 25. Therefore the leg lengths must be 7 and 24. The legs are perpendicular to one another. If we let the base be 7 and the height 24, then the area of the triangle is A = (1/2)(base)(height), or
A = (1/2)(7)(24) = 84 units^ 2

A loan of $12,651 was repaid at the end of 8 months What size repayment check (principal and interest) was written, if a 7.5% annual rate of interest was charged?The amount of the repayment check was $(Round to two decimal places)
Answers
We have a loan with a principal of $12,651.
It is paid in 8 monthly payments.
The annual rate of interest is 7.5%.
We then have to calculate the amount of each monthly payment.
This can be calculated using the annuity formula with subperiods.
The formula is:
\(M=\frac{P\cdot\frac{r}{m}}{1-(1+\frac{r}{m})^{n\cdot m}}\)For this problem we have a principal P = 12,651, an interest rate r = 0.075, the subperiods are months so m = 12, and the number of payments is n*m = 8.
We can replace and solve as:
\(\begin{gathered} M=\frac{12651\cdot\frac{0.075}{12}}{1-(1+\frac{0.075}{12})^{-8}} \\ M=\frac{12651\cdot0.00625}{1-(1+0.00625)^{-8}} \\ M=\frac{79.06875}{1-(1.00625)^{-8}} \\ M\approx\frac{79.06875}{1-0.95138} \\ M\approx\frac{79.06875}{0.04862} \\ M\approx1626.26 \end{gathered}\)Answer: the monthly payment in each check was $1626.26.

Two dice are rolled. Determine the probability of the following. ("Doubles" means both dice show the same number.)
Rolling an even number or doubles
Answers
The probability of the Doubles" means both dice show the same number is 36.
What is probability?When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The probabilities of these two outcomes must be added in order to get the likelihood of rolling an even number or doubles, but since we have already tallied those outcomes twice, the probability of rolling both doubles and an even number must be subtracted. The probability of rolling doubles and an even number is 1/36 since rolling two sixes is the only method to get a double and an even number.
The likelihood of rolling an even number or doubles is thus:
The formula for P(even number or doubles) is P(even number) = P(even number) + P(doubles) - P(even number and doubles) = 1/2 + 1/6 - 1/36 = 19/36.
The odds of rolling an even number or two doubles are 19/36.
Therefore, the probability of the Doubles" means both dice show the same number is 36.

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere
Answers
The volume of the sphere is approximately 3431.82 cubic miles.
To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.
In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.
C = 2πr
60 = 2πr
Divide both sides of the equation by 2π:
r = 60 / (2π)
r = 30 / π
Now that we have the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr³
V = (4/3)π(30/π)³
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)(27000/π²)
V = (4/3)(27000/9.87) (approximating π to 3.14)
V ≈ 3431.82 cubic miles
Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

Part A: Choose one value for a and one value for b that would make both of the following inequalities true:
a < b and |b| < |a|
Answers
The correct answer is, by choosing a = -2 and b = 1, we satisfy both inequalities .a < b:
To make both inequalities true, we need to select values for a and b that satisfy the given conditions:
a < b: This inequality means that the value of a should be less than the value of b.
|b| < |a|: This inequality means that the absolute value of b should be less than the absolute value of a.
One possible solution that satisfies both conditions is:
a = -2
b = 1
With these values, we have:
-2 < 1 (a < b)
|-1| < |2| (|b| < |a|)
Therefore, by choosing a = -2 and b = 1, we satisfy both inequalities.a < b:
This inequality states that the value of a should be less than the value of b. In other words, a needs to be positioned to the left of b on the number line. To satisfy this condition, we can choose a to be any number that is less than b. In the example I provided, a = -2 and b = 1, we can see that -2 is indeed less than 1, fulfilling the requirement.
|b| < |a|:
This inequality involves the absolute values of a and b. The absolute value of a number is its distance from zero on the number line, always resulting in a non-negative value. The inequality states that the absolute value of b should be less than the absolute value of a. To satisfy this condition, we can choose b to be any number with a smaller absolute value than a. In the example I provided, |1| is less than |(-2)|, as 1 is closer to zero than -2, fulfilling the requirement.
By selecting a = -2 and b = 1, we satisfy both inequalities: a < b and |b| < |a|. The specific values of -2 and 1 were chosen as an example, but there are multiple other values that would also satisfy the given conditions. The important aspect is that a is indeed less than b, and the absolute value of b is smaller than the absolute value of a.

Your friend decided to join a bmx course so he can race with his friends. The
courses charges $7 per race after the membership fee. Your friend has raced 28
times and paid a total of $210, including the membership fee. What is the
membership fee? How much would he pay if he races 39 times? *
Answers
Answer:
He would pay $287 if he races 39 times
Thus, the membership fee is $14.
Step-by-step explanation:
Linear Modeling
The situation described in the problem can be modeled as the equation of a line which has the form:
\(y=ax+b\)
Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.
We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:
\(210=7(28)+b\)
Operating:
\(210=196+b\)
b=14
Thus, the membership fee is $14.
The linear model is now:
\(y=7x+14\)
If he races x=39 times, your friend would pay:
\(y=7(39)+14=287\)
y=287
He would pay $287 if he races 39 times

Finding horizontal and vertical asymptotes of a rational function: Quadratic numerator or denominator
Answers
Given the function:
\(f(x)=\frac{2x^2+10x+12}{-2x+1}\)You know that it is a Rational Function because it has the following form:
\(f(x)=\frac{p(x)}{q(x)}\)Where the numerator and the denominator are polynomials and:
\(q(x)\ne0\)By definition, an Asymptote is a line that the function approaches but it does not touch it and it does not intersect.
To find the Vertical Asymptote, you can follow these steps:
1. Take the denominator of the function and make it equal to zero.
2. Solve for "x".
Then, the Vertical Asymptote is:
\(\begin{gathered} -2x+1=0 \\ -2x=-1 \\ \\ x=\frac{-1}{-2} \\ \\ x=\frac{1}{2} \end{gathered}\)To find the Horizontal Asymptote, you can follow these steps:
1. Identify the numerator of the function:
\(2x^2+10x+12\)2. Identify its denominator:
\(-2x+1\)3. Identify the degree of the numerator and the degree of the denominator:
- Since the highest exponent of the numerator is 2:
\(Degree=2\)- Since the highest exponent of the denominator is 1:
\(Degree\colon1\)4. Since the degree of the numerator is greater than the degree of the denominator by 1, you can determine that there is no Horizontal Asymptote.
Then, the steps to graph the function are:
• Draw the Vertical Asymptote on the Coordinate Plane (this must be a dotted line or a dashed line).
,• Find the x-intercept as follows:
Substitute this value of "y" into the function and solve for "x":
\(f(x)=y=0\)Then:
\(\begin{gathered} (0)(-2x+1)=2x^2+10x+12 \\ 0=2x^2+10x+12 \end{gathered}\)Notice that you need to use the Quadratic Formula to find the x-values:
\(x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}\)Then:
\(\begin{gathered} x=\frac{-10\pm\sqrt[]{(10)^2-(4)(2)(12)}}{2\cdot2} \\ \\ x_1=-2 \\ x_2=-3 \end{gathered}\)Now you know the x-intercepts.
• Find the y-intercept by substituting this value of "x" into the function and evaluating:
\(x=0\)Then, you get:
\(\begin{gathered} y=\frac{2(0)^2^{}+10(0)+12}{-2(0)+1} \\ \\ y=\frac{12}{1} \\ \\ y=12 \end{gathered}\)• Now you can find different points on the function by substituting several values of "x" and finding the corresponding y-values.
Then:
\(\text{For }x=4\rightarrow y=\frac{2(4)^2+10(4)+12}{-2(4)+1}\approx-12\)\(\text{For }x=5\rightarrow y=\frac{2(5)^2+10(5)+12}{-2(5)+1}\approx-12.44\)\(\text{For }x=10\rightarrow y=\frac{2(10)^2+10(10)+12}{-2(10)+1}\approx-16.42\)\(\text{For }x=20\rightarrow y=\frac{2(20)^2+10(20)+12}{-2(20)+1}\approx-25.95\)\(\text{For }x=-10\rightarrow y=\frac{2(-10)^2+10(-10)+12}{-2(-10)+1}\approx5.33\)\(\text{For }x=-20\rightarrow y=\frac{2(-20)^2+10(-20)+12}{-2(-20)+1}\approx14.93\)• Finally, plot the points on the Coordinate Plane and graph the function by connecting the points (remember that they must be connected with curves).
Therefore, the answer is (The dashed line is the Vertical Asymptote. There is no Horizontal Asymptote):

In a survey on internet usage , it was found that out of a total of 27 people, 16 use ADSL lines, 15 use wireless internet and 3 use neither of the two . what is the probability that a person chosen at random uses both internet connections
Answers
The probability that a person chosen at random uses both internet connections is 1/9
Total number of people = 27
Number of people who use ADSL lines = 16
Number of people who use wireless internet = 15
Number of people who use neither of the two = 3
Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.
Then A + B + A∩B + 3 must be equal to 27
A + B + A∩B = 24
further, we can see that
(A + A∩B) = 16
B + 16 = 24
B = 8
Also, (B + A∩B) = 15
8+ A∩B = 15
A∩B = 7
Thus, the number of people who use both internet connections = 7
Now, P(A∩B) = 7/27
= 1/9
Hence, probability that a person chosen at random uses both internet connections is 1/9.

What is the probability that a customer is female and lives in a dorm or is female and lives in 'Other'? Express your answer as a fraction or a decimal number rounded to four decimal places.
Answers
Answer: 0.2254
Step-by-step explanation:
Let E= Event of getting of female lives in a dorm.
F = Event of getting of female lives in a 'Other'.
From the table , n(E) = 276 and n(F) = 99
and n(E∩F) = 0 [E and F are Mutually exclusive]
Now, n(E∪F)= n(E) + n(F) - n(E∩F)
= 276+99-0
= 375
also, n(S) =1664 (Sample size)
Required probability : \(P(E\cup F)=\dfrac{n(E\cup F)}{n(S)}\)
\(=\dfrac{375}{1664}\approx0.2254\)
Hence, the probability that a customer is female and lives in a dorm or is female and lives in 'Other' = 0.2254
