A right triangle's hypotenuse is 1 cm longer than twice the length of the shortest side.
The third side is 1 cm less than twice the shortest side.
Find the length (in cm) of the hypotenuse.
The length (in cm) of the hypotenuse is 17 cm.
What is Pythagoras' theorem?According to Pythagoras' theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
H² = P² + B²
Let the hypotenuse = H
Shortest side = B
Third side = P
So, according to the question
H = 2B +1 ..... (1)
P = 2B -1 ..... (2)
Use Pythagoras' theorem,
H² = P² + B²
(2B+1)² = (2B-1)² + B²
4B² + 1 + 4B = 4B² + 1 - 4B + B²
4B = - 4B +B²
B² =-8B
B = - 8
But the length cannot be negative, so B = 8 cm
The length of the shortest side = 8 cm
So the hypotenuse will be
H = 2B + 1
= 2(8) + 1
= 17 cm

If LR equals 12 and PR equals 4, then: LP = 8 because LP + PR = LR according to the Segment Addition Postulate, and 8 + 4 = 12 using substitution.
What is the Segment Addition Postulate?The Segment Addition Postulate states that when there are two endpoints on a line segment (L) and (C), a third point (P) would lie on the line segment (LR), if and only if the magnitude of the distances between the endpoints satisfy the requirements of this equation LP + PR = LR.
This ultimately implies that, the Segment Addition Postulate is only applicable on a line segment that contains three collinear points.
By applying the Segment Addition Postulate to the given endpoints, the value of LP is given by:
LP + PR = LR
LP = LR - PR
Substituting the given parameters into the formula, we have;

if the probability of a is 0.45 and the probability of the intersection of a and b is 0.15, then the probability that b will occur given that a has occurred is:
The probability that b will occur given that a has occurred is 2/5 as the probability of a is 0.45 and the probability of the intersection of a and b is 0.15.
What is probability?It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. For instance, the theoretical chance of getting a head when tossing a coin is 12. Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution.
Here,
P(A)=0.45
P(A∩B)=0.15
P(A∪B)=1
P(B)=1-(0.45+0.15)
=1-0.60
=0.4
=2/5
With a probability of 0.45 and a and b's intersection having a 0.15 probability each, the likelihood that b will happen given that a has happened is 2/5.

If a is inversely related to the square of b, and a = 3 when bis

(A) a = 4, b = 12
(B) a = 12, b = 4
(C) a = 8, b = 3
(D) a = 2, b = 4
(E) a = 6, b = 4
Another possible values for a and b are a = 12 and b = 4
How to find another possible value for a and b?
A variation is a relation between a set of values of one variable and a set of values of other variables
Given that: a is inversely related to the square of b, and a = 3 when bis
8.
This can be written as:
a α 1/b²
a = k/b² (where k is a constant)
k = ab²
since a = 3 and b = 8.
Thus, k = 3 × 8² = 3 × 64 = 192
For a value to be another possible value for a and b, they must give k = 192 when substituted into the equation k = ab²:
a = 4, b = 12: k = 4 × 12² = 576
a = 12, b = 4: k = 12 × 4² = 192
a = 8, b = 3: k = 8 × 3² = 72
a = 2, b = 4: k = 2 × 4² = 32
a = 6, b = 4: k = 6 × 4² = 96
The values that produce k = 192 are a = 12 and b = 4. Therefore, another possible value for a and b is a = 12 and b = 4. So option B is the answer

assume that the heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches. the u.s. marine corps requires that the heights of men be between 64 and 78 inches. if 500 men want to enlist in the u.s. marine corps, how many would you not expect to meet the height requirements?
The percentage of men who didn't expect to meet the height requirements be 96.29%
Given, that the heights of men are normally distributed with a mean of 69.0 inches and a standard deviation of 2.8 inches.
Find the percentage of men who meet the height requirements.
z(64) = (64-69)/2.8 = 1.7857
z(78) = (78-69)/2.8 = 3.2143
P(64 <= x <= 78) = P(1.78457<= z <=3.2143) = 0.0371 = 3.71%
So, the percentage of men who meet the height requirements be 3.71%
Now, the percentage men who didn't expect to meet the height requirements be
100 - 3.71 = 96.29%

g in october 2012, apple introduced a much smaller version of the apple ipad, known as the ipad mini. weighing less than 11 ounces, it was 50% lighter than the standard ipad. battery tests for the mini ipad showed that battery life is uniformly distributed between 8.5 and 12 hours. calculate the expected value to two decimals.
Using the concepts of probability, we got that 0.4286 is the probability that the battery life for an iPad Mini will be 10 hours or less which is about 42.86%.
From the given information;
Let X represent the continuous random variable with uniform distribution U (A, B) . Therefore the probability density function can now be determined as :
[tex]f_X(x)[/tex] = [tex]\frac{1}{B-A}[/tex] where A<x<B
where A and B are the two parameters of the uniform distribution
From the question;
Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours
So; Let A = 8,5 and B = 12
Therefore; the mathematical expression for the probability density function of battery life is :
[tex]f_X(x)[/tex] = [1 / (12-8.5)]8.5<x<12
[tex]f_X(x)=[/tex](1/3.5)8.5<x<12
The probability that the battery life for an iPad Mini will be 10 hours or less can be calculated as:
F(x) = P(X ≤x)
F(10)=[tex](x-A)/(B-A)[/tex]
F(10)=(10-8.5)/(12-8.5)
F(10)=1.5/3.5
F(10)=0.4286
