The bijection could be defined from the set of numbers and it is proved.
We can define a bijection f from S to T as follows: for any integer x in S, let f(x) = x + 1.
To show that f is a bijection, we need to prove that it is both injective and surjective.
To prove that f is injective, suppose f(x) = f(y) for some x, y in S. Then x + 1 = y + 1, which means x = y. Thus, f is injective.
To prove that f is surjective, let y be an arbitrary element of T. Since y is odd, we can write y = 2n + 1 for some integer n. Now consider the element x = 3n in S. We have f(x) = x + 1 = 3n + 1 = y, so f is surjective.
Therefore, f is a bijection from S to T, so |S| = |T|.

In a pizza dough recipe, the volume of water before mixing is 25% of the total ingredient volume. Which equation represents the relationship between the volume of water and the total volume of all ingredients? 1 (Let w represent the volume of water, and let t represent the total volume of all ingredients.)
a) t = 0.2w
b)t = 0.25w
c) = 4w
d) = 5w
The equation that relates the volume of water and the total ingredient volume is the one in option C, it is written as:
t = 4*w
Which equation represents the relationship?So we know that the volume of water before mixing is 25% of the total ingredient volume.
So if we define the variables:
w = volume of watert = total volume of ingredients.Then we know that w is equal to the 25% of t.
Then the relation can be written as:
w = (25%/100%)*t
Where we divide the percentage by 100% so we write a decimal number instead of a percentage.
Now we can simply it so we get:
w = (25%/100%)*t
w = 0.25*t
Now we can isolate t to get:
t = (1/0.25)*w
t = 4*w
So the correct option is C.

find the sum of all positive rational numbers that are less than 10 and that have denominator 30 when written in lowest terms.
the sum of all positive rational numbers that are less than 10 and that have a denominator 30 is 400.
What is Rational Number?
Numbers that may be expressed in the form p/q, where p and q are integers and q0, are considered rational numbers. Because fractions cannot have a negative numerator or denominator, they differ from rational numbers in this respect. Because of this, the numerator and denominator of a fraction are whole numbers (denominator 0), unlike in the case of rational numbers, when they are both integers.
So to convert a fractional to reduce form we have to divide by 10 to power how many digits thereafter decimal point, and make sure that the numerator or denominator doesn't have commonly divisible.
As a small addition, you get 4+12+20+…+76, which is an arithmetic sequence. There are ten terms, so you can use
So the sum will be 10(4+76)/2 = 400
Hence the sum of all positive rational numbers that are less than 10 and that have a denominator 30 is 400.

the value of r will be the intrinsic exponential growth rate and t represent time.
⇒ If there is no limiting factors, then the logistic model would be exponential according to formula:

r = ln a
a = e^r
given r= 0.2
