A triangle has sides with lengths of 24 meters, 45 meters, and 49 meters. Is it a right triangle?
Answers
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Use the Pythagorean Theorem to determine if these sides are sides of a right triangle.
\(a^{2}+b^{2}=c^{2}\)
Plug in your length sides. Have the longest side represent your c variable.
a= 24
b= 45
c= 49
Solve for the equation.
\(24^{2}+45^{2}=49^{2}\)
576+2025= 2401
2601=2401
These side lengths in a triangle are not a right triangle because 2601 does not equal 2401.

How many triples of three positive integers have a product of 16?
Answers
There are 15 possible triples of three positive integers whose product is 16.
According to this question, we must find the quantity of all possible triples such that they have a product of 16. By factor decomposition, we have that 16 is equal to the following product of prime numbers:
\(16 = 2^{4}\)
There are the following triples considering order of factors:
(i) \(\{16, 1, 1\}\), (ii) \(\{1, 16, 1\}\), (iii) \(\{1, 1, 16\}\), (iv) \(\{2, 8, 1\}\), (v) \(\{8, 2, 1\}\), (vi) \(\{8, 1, 2\}\), (vii) \(\{2, 1, 8\}\), (viii) \(\{1, 2, 8\}\), (ix) \(\{1, 8, 2\}\), (x) \(\{1,4,4\}\), (xi) \(\{4, 1, 4\}\), (xii) \(\{4,4,1\}\), (xiii) \(\{2,2,4\}\), (xiv) \(\{2, 4, 2\}\), (xv) \(\{4,2,2\}\)

Answers
The probability that Sergio's number is larger than the sum of the two numbers chosen by Tina is 0.4
We can calculate the probability by finding the number of favorable outcomes, i.e., the number of ways that Sergio can choose a number that is larger than the sum of the two numbers chosen by Tina, and dividing it by the total number of possible outcomes, which is
5C2 * 10C1 = (5!/(2! * 3!)) * 10
= 100
Tina's sum Sergio's favorable outcomes
3 7
4 6
5 5
6 4
7 3
8 2
9 1
For example the sum 5 can be achieved by two ways, that is 1+4 and 2+3. So
Tina's sum Number of ways to achieve that sum
3 1
4 1
5 2
6 2
7 2
8 1
9 1
The number of favourable outcomes is
= 1*7 + 1*6 + 2*5 + 2*4 + 2*3 + 1*2 +1*1
= 40
So probability is

Cone formula: \(\pi\)hr^2/3
Plugging in the values, we get the volume is 301.59
Let me know if this helps :)
Answer:
96π
301.59
Step-by-step explanation:
The volume of a cone can be calculated using the following formula:
\(V=\frac{1}{3}bh\)
b is the base and h is the height. The base formula for a circle (area):
\(b=\pi r^2\)
Insert this value into the formula:
\(V=\frac{1}{3}\pi r^2h\)
Simplify the formula:
\(V=\frac{\pi r^2h }{3}\)
Now insert the known values:
\(V=\frac{\pi(6)^2(8) }{3}\)
Simplify:
\(V=\frac{\pi*36*8 }{3}\\\\V=\frac{288\pi }{3}\\\\V=96\pi\)
The volume is 96π units³ or 301.59 units³.

The chances that a student will get 7 marks out of 10 in first attempt of a certain Quiz while attempting Quiz on BlackBoard LMS is 40%. Suppose that 20 students are selected at random then find a probability that i)Exactly 12 students will get 7 marks out 10 in the Quiz. ii)Fewer than 10 students will get 7 marks out 10 in the Quiz. iii)At least 5 students will get 7 marks out 10 in the Quiz.
Answers
Answer:
i) \(P(X=12)=0.0355\)
ii) \(P(X<10)=0.7553\)
iii) \(P(X\geq 5)=0.9490\)
Step-by-step explanation:
Let's start by defining the random variable ⇒
\(X:\) '' Number of students that will get 7 marks out of 10 in first attempt of a certain Quiz while attempting Quiz on BlackBoard LMS ''
\(X\) is a discrete random variable.
The probability of a randomly selected student getting 7 marks out of 10 is 0.4
(This is a data from the question).
Now, if we assume independence between the students while they are doing the Quiz and also we assume that this probability remains constant , we can modelate \(X\) as a binomial random variable ⇒
\(X\) ~ Bi (n,p)
Where ''n'' and ''p'' are the parameters of the variable.
''n'' is the number of students attempting the Quiz and ''p'' is the probability that a student will get 7 marks out of 10 which is 0.4 ⇒
\(X\) ~ Bi (20, 0.4) in the question.
The probability function for \(X\) is
\(p_{X}(x)=P(X=x)=\left(\begin{array}{c}n&x\end{array}\right)p^{x}(1-p)^{n-x}\) (I)
Where \(\left(\begin{array}{c}n&x\end{array}\right)\) is the combinatorial number define as
\(\left(\begin{array}{c}n&x\end{array}\right)=\frac{n!}{x!(n-x)!}\)
Replacing the parameters in the equation (I) ⇒
\(P(X=x)=\left(\begin{array}{c}20&x\end{array}\right)(0.4)^{x}(0.6)^{20-x}\) (II)
For i) we need to find \(P(X=12)\)
Then, we only need to replace by \(x=12\) in equation (II) ⇒
\(P(X=12)=\left(\begin{array}{c}20&12\end{array}\right)(0.4)^{12}(0.6)^{8}=0.0355\)
For ii) we need to calculate \(P(X<10)\)
This probability is equal to ⇒ \(P(X<10)=P(X\leq 9)\) and to calculate it we need to sum \(P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)\)
\(+P(X=6)+P(X=7)+P(X=8)+P(X=9)\)
We can do it summing each term or either using any program.
The result is \(P(X<10)=P(X\leq 9)=0.7553\)
Finally for iii) we need to find ⇒ \(P(X\geq 5)\)
This probability is equal to ⇒ \(P(X\geq 5)=1-P(X\leq 4)\) ⇒
\(1-P(X\leq 4)=1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)]\)
Again we can find each term by using the equation (II) or either using a program. The result is \(P(X\geq 5)=0.9490\)

The product of an integer 2 and a fraction 7/10 is 7/5.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, A an integer 2 and we have to multiply it by a fraction 7/10.
Now, We know every integer can be written as a rational number.
Therefore, 2 can be written as 2/1.
Hence, The multiplication of 2/1 and 7/10 is,
= (2/1)×(7/10).
= 14/10.

which of the following statements is true? the volume of the solid formed by rotating the region bounded by the graph of y=x^2, x=3, y=0 around the y-axis is 1.pi ?(x from 0 to 3) x^3 dx 2.pi ?(y from 0 to 9) (3-?y)^2 dy 3.pi ?(y from 0 to 9) (9-y) dy a.1 only b.2 only c.3 only d.1 and 3 e.1 and 2
Answers
The volume of the solid is π (243/5), which corresponds to option 1.
The correct answer is (d) 1 and 3.
To find the volume of the solid formed by rotating the region bounded by the graph of y=x^2, x=3, y=0 around the y-axis, we can use the formula:
V = ∫[a,b] π (f(x))^2 dx
where a and b are the limits of integration (in this case, 0 and 3), and f(x) is the function defining the curve being rotated (in this case, f(x) = x^2).
Using this formula, we get:
V = ∫[0,3] π (x^2)^2 dx
= ∫[0,3] π x^4 dx
= π [x^5/5] from 0 to 3
= π [(3^5/5) - (0^5/5)]
= π (243/5)
So the volume of the solid is π (243/5), which corresponds to option 1.
Option 2 is incorrect because the integral given in that option corresponds to the volume of the solid formed by rotating the region bounded by the graph of y=3-x, x=0, y=0 around the y-axis, not the region defined in the question.
Option 3 is also incorrect because the integral given in that option corresponds to the volume of the solid formed by rotating the region bounded by the graph of y=x^2, x=0, y=9 around the x-axis, not the y-axis as required in the question.
