Even though this relationship is proportional, not all of these ratios are equal.
What is the solution to the 3 to 5 ratio?Verify that the ratios provided are equal. The ratios of 3:5 and 15:25 are both equal. Because the first ratio 3: 5 can be derived by multiplying the ratio 15: 25 by 5 on both the numerator and denominator. The initial ratio of 3: 5 can be multiplied by 5 to get the ratio 15: 25, and vice versa.

What is the Gamma Distribution ?
A distribution which is described as two parameters – shape parameter and inverse scale parameter, having continuous probability distributions.
Given,
Z be a standard normal random variable: i. E. , Z ∼ N(0, 1).
Using the distribution method, find the pdf of U = Z 2.
And Using result from previous part, show that pdf of U follows a special case of Gamma distribution and also of χ 2 distribution.
Suppose e Z ∼ N (0, 1), then
mZ (t) = 1√2πetxe−x2/2dx
= et2/21/√2π
[tex]e ^ {-(x-t)^{2} /2[/tex] dx

By solving, we see that the product of the polynomials 4 - a and a3 + 7a - 18 is a3 + 3a2 + 46a + 72.
what is polynomial ?The location on the y-axis where the slope of the line passes is known as the intersection point in mathematics. a point on a line or curve where the y-axis crosses. The equation for the straight line is given as Y = mx+c, where m denotes the slope and c the y-intercept. In the intercept form of the equation, the line's slope (m) and y-intercept (b) are highlighted. The slope and y-intercept of an equation with the intercept form (y=mx+b) are m and b, respectively. There are several equations that can be rewritten to look like slope intercepts. The slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0, for example.
given
(4 - a) * ( a3 + 7a - 18 )
= 4a3 + 28a - 72 - a4 + 7a2 + 18 a

Marla is four years less than twice as old as Darla. If the sum of their ages is 47, how old is Marla?
Marla is 30 years old.
Let marla age be x and Darla age be y
Given : Marla is four years less than twice as old as Darla
What is equation ?
In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Marla is four years less than twice as old as Darla can be represented as : 2y - x = 4
sum of their ages is 47 can be represented as : x + y = 47
Solving both the equation using addition we got ,
3y = 51
y = 17
Substituting the value of y in x + y =47 , we get
x + 17 = 47
x = 47 -17
x = 30
Hence , Marla is 30 years old.

x^2 - 19x +c
Answer:
Step-by-step explanation:
We need to transform the given x^2 - 19x + c into the form
(x - a)^2 + d
by completing the square:
1. Take half of the coefficient (-19) of x, obtaining -19/2.
2. Square this result, obtaining 361/4.
3. Add this to x^2 - 19x, and then immediately subtract it:
x^2 - 19x + c becomes x^2 - 19x + 361/4 - 361/4+ c
4. Replace the first three terms with (x - 19/2)^2:
x^2 - 19x + 361/4 - 361/4+ c => (x - 19/2)^2 - 361/4 + c
5. Put this into final form: (x - 19/2)^2 - (361/4 - c)

What is the length of JL, nearest tenth
Answer:
I believe the answer is 45.
Step-by-step explanation:
a 90 degree angle is represented by a square on the corner.
So half of 90 is:
90 ÷ 2 = 45
the angle next to the letter M is 90 degreess, so the other side of the line is also 90 degrees.
45 + 90 = 135
and 180 - 135 = 45
(You subtract 135 from 180 since " the sum of angles of a triangle equals the straight angle", which is 180 degrees.
So, the length of JL is equal to 45 degrees.

The prime factor trees for 24 and 84 are attached in the image below. The Lowest Common Multiple of 24 and 84 is 168.
What are prime factors?A natural number other than 1 whose only factors are 1 and itself is said to be a prime factor. In actuality, the first few prime numbers are 2, 3, 5, 7, 11, and so forth. The lowest of two or more natural numbers' common multiples is referred to as the Lowest Common Multiple (LCM). A prime factor is a natural integer, other than 1, whose sole factors are itself and 1. Actually, 2, 3, 5, 7, 11, and so forth are the first few prime numbers. The term "Lowest Common Multiple" refers to the common multiple of two or more natural integers that is the lowest (LCM).
The prime factors of 24 are: 2,2,2 and 3.
The prime factors of 84 are: 2,2,3 and 7.
Now, The Lowest Common Multiple (LCM) of 24 and 84 is calculated using the prime factors of both the numbers.
LCM= 2*2*2*3*7= 168
Hence, The Lowest Common Multiple of 24 and 84 is 168.
