Step-by-step explanation:

Assuming the triangle is a right triangle, we can use the Pythagorean theorem, a^2+b^2=c^2

Plugging our numbers in, we get 5^2+b^2=13^2

25+b^2=169

b^2=144

b=12

I also believe that this is a 5 12 13 triangle so if you remember those, you can automatically know the lengths!

The simplified expressions for (A), (B) and (C) are:

(A) [tex]f(x+h) = 4x + 4h - 6[/tex]

(B) [tex]f(x+h) * f(x) = 16x^2 + 4xh - 24x + 4h^2 - 24h + 36[/tex]

(C) [tex]f(x+h) - f(x) / h = 4[/tex]

To simplify we use the given method.

A)

[tex]f(x+h) = 4(x+h) - 6 = 4x + 4h - 6[/tex]

B) [tex]f(x+h) * f(x) = (4x + 4h - 6) * (4x - 6) = 16x^2 + 4xh - 24x + 4h^2 - 24h + 36[/tex]

C)

[tex]f(x+h) - f(x) / h = (4x + 4h - 6) - (4x - 6) / h = 4h / h = 4[/tex]

So the simplified expressions for (A), (B) and (C) are:

(A) [tex]f(x+h) = 4x + 4h - 6[/tex]

(B) [tex]f(x+h) * f(x) = 16x^2 + 4xh - 24x + 4h^2 - 24h + 36[/tex]

(C) [tex]f(x+h) - f(x) / h = 4[/tex]

Please note that in (C) the difference of the functions is divided by h, not multiplied.

Note that the number of students, in a dass of 35, who improve their score from the first midterm to the second midterm is a discrete variable.

A discrete variable is one that can only have particular, unique values and cannot have any other values in between. The number of students who increase their score is a whole number that can only take on specific values (e.g., 0, 1, 2, etc.), indicating that it is a discrete variable.

A quantitative variable in mathematics and statistics can be continuous or discrete depending on whether it is normally obtained by measuring or counting. The variable is continuous in that interval if it can take on two specific real values while simultaneously taking on all real values between them.

Thus, it is correct to state that the number of students, in a dass of 35, who improve their score from the first midterm to the second midterm is a discrete variable.

Therefore,  the solution of given problem of probability is there is a 0.397 percent chance that a randomly chosen male will have a systolic blood pressure below 100.

A branch of mathematics called probability theory determines the likelihood that an event will occur or that a statement is true. A possibility is a number from 0 and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or chance that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed as percentages ranging from 0% to 100% and from 0 to 1.

Here,

Considering the query

In a particular municipality, men's systolic blood pressure has a median of 105 as well as a standard deviation = 9, which is considered to be regularly distributed.

Probability that the systolic blood pressure of a man chosen at random will be less than 100

P(x < 100)

Through the use of normalized normal distribution

=> N(100 -105)/9 \s=> N (-5/9)

We have a>0 and N(-a) = 1 - N(a).

=> 1 - N (-5/9)

=> 1 - N(0.556) (0.556)

=>1 - 0.6026

=> 0.3979

≈ 0.397 (nearest hundredths) (nearest thousandth)

Therefore, there is a 0.397 percent chance that a randomly chosen male will have a systolic blood pressure below 100.

Therefore . the solution of the given problem of distance comes out to be it follows that there are √17 units separating the two points.

Distance is a measure of an object's travels. Distance, put simply, is what an item travels over in a particular amount of time, or t. The shortest path an object can take while moving is displacement, nevertheless. We commonly incorporate the physical quantities of distance and displacement.

Here,

provided are (6, -3) & (2, -2)

Now, the separation between points (a, b) & (c, d) is

d= √(c-a)² + ( d- b) ²

Therefore, d= √(-3+2)² + (2-6)²

d= √ 1 + 16

Step-2: Model the given situation mathematically.

In other words, the conditional probability of the event that the diagnostic test gives a negative result (not A), given that the tested person does not have the disease (E2 = not E1) is given to be 90%

Thus P(not A/E2)=90%

Further, it is given that five percent of the population has the disease. In other words, the event that a person has the disease (E1) has the probability of 5% Thus P(E1)=5%

Therefore , the solution of the given problem of parallel line comes out to be   MP =22.

Geometry refers to parallel lines as beams, straight lines that never overlap. Parallel planes are those that never cross each other while occupying the same three-dimensional space. Curves which are equal with each other and keep a predetermined minimum separation from one another must not overlap or intersect. Parallel lines on a plane are those that always have the same distance between them. A parallel line cannot be crossed. Perpendicular lines are those that intersect directly at a 90 degree angle.

Here,

Given :  PQ || MN

=> PQ =MP+2

=> PO = 12 , MN = 12

So,

A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry. The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.

A face is a flat surface, an edge is a straight line connecting two faces, and a vertex is the corner of the form. Faces, edges, and vertices of three-dimensional forms are all unique. In the course of our daily activities, we come into contact with numerous things of all sizes and forms.

The length of each side:

CD: C(2,4) and D(1,1) = sqrt((1-2)^2 + (1-4)^2) = sqrt(1 + 9) = sqrt(10)

DE: D(1,1) and E(5,0) = sqrt((5-1)^2 + (0-1)^2) = sqrt(16+1) = sqrt(17)

EF: E(5,0) and F(3,4) = sqrt((3-5)^2 + (4-0)^2) = sqrt(4+16) = sqrt(20)

FC: F(3,4) and C(2,4) = sqrt((2-3)^2 + (4-4)^2) = sqrt(1) = 1
