Seaborgium-266 will have 60 half life in 30 minutes.

It is given in the question that Seaborgium-266 has a half life in 30 sec.

Since half life is given in seconds , convert 30 min in seconds .

1 min= 60 sec

so 30min= 30*60 sec

30 min= 1800 sec.

According to the question

30 sec = 1 half life

1 sec = 1/30 half life

For 1800 sec

[tex]1800 sec = 1800*\frac{1}{30}[/tex] half life

=60 half life

Therefore , Seaborgium-266 will have 60 half life in 30 minutes.

There will be 660.425 dollars cost to fill up the pool.

The newly built single-depth olympic size swimming pool (50m by 25m by 2m) needs to be filled up.

Here,

Length of swimming pool = 50m

Width of swimming pool = 25m

Depth of swimming pool = 2m

The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.

The volume of a cuboid is length × breadth× height

As it is 3D geometry

The volume will be L×W×H i.e. 50×25×2 = 2500 m³

Since one cubic meter is equal to 264.172052 gallons,

So 2500 m³ = 264.17 × 2500 = 660425 gallons

If the water bill is equivalent to $1 per 1000 gallons

So 660425/1000 = 660.425

Hence, there will be 660.425 dollars cost to fill up the pool.

The equation of point slope form of (1,10) and (5,42) is -2.7x + y - 3 = 0.

A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).

given that

the coordinates points are (0,3) and (3,11)

(x1,y1) = (0,3)

(x2, y2) = (3,11)

The formula of point-slope is

(y - y1) = m(x - x1)

Here,

x1 = 0 and y1 = 3 but we don't know the value of m.

now,find the value of m using the following formula

[tex]m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]

now, substitute the values, we get

[tex]m = \frac{(11 - 3)}{(3 - 0)}[/tex]

[tex]m = \frac{8}{3}[/tex]

m = 2.7

so, the value of m is 2.7.

substitute these values into the point-slope formula

(y - 3) = 2.7(x - 0)

y - 3 = 2.7x - 0

-2.7x + y - 3 = 0

Hence, the equation of point slope form of (1,10) and (5,42) is -2.7x + y - 3 = 0.

AB = CA This triangle comprises two sides that are congruent. As a result, it is isosceles.

A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using single or more numbers, or coordinates.

Use the Distance Formula to find the lengths of AB ,BC and CA.

AB has endpoints A(–2, –1) and B(–1, 3).

AB = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

AB = √((-1 - (-2))² + (3 - (-1))²)

     = √((1)² + (4)²)

     = √(1 + 16)

    = √(17)

BC has endpoints B(–1, 3) and C(2, 0).

BC = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

BC = √((2 - (-1))² + (0 - 3)²)

      = √((3)² + (-3)²)

       = √(9 +9)

       = √(18)

CA = has endpoints C(2, 0) and A(–2,–1).

CA = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

As per the question statement, it is suggested that people of age, less than or equal to 18 years and of age, greater than or equal to 50 years, should be the first to get a flu vaccine.

We are required to define a variable to the age group suggested to be prioritized for to vaccinate with the flu vaccine, and describe the question mentioned situation in the form of a compound inequality.

To start with, let us first determine the variable. It is as simple as assuming any alphabet, say "A", to be the age group, suggested to be prioritized for to vaccinate with the flu vaccine.

Since, suggested that people of age, less than or equal to 18 years should be amongst the the first to get a flu vaccine, thus "A" must be less than equal to 18, i.e., [tex][A\leq 18][/tex]...(1)

Similarly, suggested that people of age, greater than or equal to 50 years should be amongst the the first to get a flu vaccine, thus "A" must be greater than equal to 50, i.e., [tex][A\geq 50][/tex]...(2)

The illustrated expression is given as

In the above expression, we do not have any inequality sign

This means that the expression is an equation i.e. equality

The transitive postulate of equality states that

if a = b and b = c, then a = c

The given equality expression illustrates the transitive postulate of equality

The probability is 1.38.

Probability is the possibility of an event occurring. We can scale the probability of an event between 0 and 1. 0 refers to an improbable event, and one refers to an event with the highest possibility. The type of probability we will use to solve this problem is the geometric distribution.

The geometric distribution is defined as a discrete probability distribution representing the probability of consecutive failures before success in a Bernoulli trial. There could be only two possible outcomes; either True (1) or False (0).

Bernoulli's trial is an experiment in which we have only two possible outcomes, success or failure. In other words, the geometric distribution repeats Bernoulli trials until it succeeds, then stops. So, achieving success is the ultimate goal and is the point that stops Bernoulli's trials from happening further.

Geometric distribution, the class of probability distributions, is based on three key assumptions, and these assumptions are defined as:

The studies conducted are independent. Each event is independent of the other.

Each attempt has only two outcomes: success or failure. If an event has any other possible output other than 0 and 1, it can not be classified as a Bernoulli trial.

The probability of success, indicated by p, is the same for each trial.

After understanding the concepts stated above now, we will move towards the actual statement of the problem. So, a scenario is given to us that tells us that the variable is from a geometric distribution setting, which means that all of the assumptions for geometric distribution will be applied. The given probability that Anita makes is,

Given = 0.46

So, to find the probability that she will get a hit on her 3rd try, we will add one possibility three times,

p = 0.46 + 0.46 + 0.46

p = 1.38

Or we can also do it like this,

p = 0.46 * 3

p = 1.38

Both ways will provide us with the correct answer.
