An agent sells life insurance policies to five equally aged, healthy people. According to recent data, the probability of a person living in these conditions for 30 years or more is 2/3. Calculate the probability that after 30 years:
O All five people are still living.
O At least three people are still living.
O Exactly two people are still living.
The number of people still living has a Binomial (n = 5, p = 2/3)
The probability of all five people still living is
P(X = 5) = (2/3)⁵ ≈ 0.1317
The probability of exactly two people living
P(X = 2) = 10 x (2/3)² (1/3)³ ≈ 0.16
The probability of at least three people still living
P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5)
≈ 0.3292 + 0.3292 + 0.1317
≈ 0.790
Probability is simply the probability that something will happen. Whenever the outcome of an event is uncertain, we can talk about the probability of a particular outcome, i.e. its likelihood. The analysis of events driven by probability is called statistics.
Probabilities can be expressed numerically by the number of desired outcomes, divided by the total number of outcomes.
Properties:
The probability of an event that cannot happen is either phi or a null set.The total number of possible outcomes in an event's sample space is its maximum probability. Any event has a probability between 0 and 1. A probability of 0 can also exist).An event cannot have a negative probability.The probability of either A or B occurring is equal to the sum of the probability of A and the probability of B if A and B are two outcomes that cannot occur simultaneously.To learn more about Probability:

Piper is building a walkway with a width of xx feet to go around a swimming pool that measures 7 feet by 6 feet. If the total area of the pool and the walkway will be 506 square feet, how wide should the walkway be?
According to the given statement the width of the walkway (x) is 8 feet.
How do you square an example?Four of the sides of a square's two-dimensional form are equal in length. In a square, all four internal angles were right angles, and the opposing sides are parallel to one another. Real-world examples of square-shaped things include floor tiles, tea towels, hexagonal tiles, cheddar cheese, and so on.
Briefing:Area of a Square = (side)(side)
Total area of the pool and walkway = 506 sq. ft
Length of the pool and walkway = 7 + 2x
Width of the pool and walkway = 6 + 2x
Thus, we will have the equation of the total area as:
(7 + 2x)(6 + 2x) = 506
4x² + 12x + 14x + 42 = 506
4x² + 26x + 42 = 506
4x² + 26x + 42 - 506 = 0
4x² + 26x - 464 = 0
2x² + 13x - 232 = 0
[tex]x = - \frac{\sqrt{169 + 1856}}{4}- \frac{13}{4} ,\\\\\quad x = \frac{\sqrt{2025}}{4} - \frac{13}{4} \\\\\quad x = \frac{45}{4}- \frac{13}{4} \\\\[/tex]

Kelly bought 4 boxes of sunglasses at a swap meet. Each box had 20, 25, or 30 pairs in it. Kelly estimates a reasonable number of sunglasses to be 70.
Kelly's estimate cannot be said to be reasonable because it falls below the range of acceptable number of sunglasses from the given amount in each box.
How to solve Algebra Word Problems?We are told that Kelly bought 4 boxes.
Now, we are told that each box had either 20, 25, or 30 pairs of sunglasses in it.
Thus;
Minimum number of sunglasses = 20 * 4 = 80 sunglasses
Maximum number of sunglasses = 30 * 4 = 120 sunglasses
Now, we are told that Kelly estimates a reasonable number of sunglasses to be 70.
From our previous calculations, the minimum possible can only be 80 and as such her estimate falls lower and we conclude that it is unreasonable.

Step-by-step explanation:
How do you know if it's a function or Nonfunction?
A function is a relationship between a set of possible inputs and outputs, where each input is associated with exactly one output.
A non-function is a relation between a set of inputs and a set of possible outputs where there is at least one input with more than one output.
The vertical line test can be used to ascertain whether a relation is a function. If you can draw a vertical line through the graph of the relationship and it intersects the graph at more than one point, then the relation is a non-function. If the vertical line intersects the graph at only one point, then the relation is a function.
Another way to determine if a relation is a function is to look at the equation defining the relation. If the equation does not contain any x's in the denominator, then the relation is a function. If the equation contains x's in the denominator, then the relation is a non-function.
For example, consider the relation defined by the equation y = x^2. This relation is a function because there are no x's in the denominator.
On the other hand, consider the relation defined by the equation y = 1/x. This relation is a non-function because the equation contains an x in the denominator.

Let f be a differentiable function such that f (2) = 4 and f (2) = − 1/2 . What is the approximation for f (2.1) found by using the line tangent to the graph of f at x = 2 ?
Using line tangent, the approximation for f(2.1) is 3.95
Given,
The point (a, f(a)) is on the line tangent to the graph of y = f(x) at x = a, which has a slope of f'(a).
The equation be like;
y - f(a) / (x - a) = f'(a)
y = f'(a) (x - a) + f(a)
Using the provided data and a = 2, we can determine that the tangent line to the graph of y = f(x) at x = 2 has equation
y = f'(2) (x - 2) + f(2)
y = -1/2 (x - 2) + 4
To compute a "approximation of f(2.1) using the line tangent to the graph of f at x = 2," one must substitute x = 2.1 for f in the equation for the tangent line (2.1). You get 2.1 when you plug this in.

The required sets of range of the corresponding functions are illustrated in the below solution part.
What is the range of a function?The range of a function is the set of all possible output values of the function.
To find the range of a function, we need to evaluate the function at every point in its domain and find the set of all possible output values.
For example, we are given the function f(x) = x² - 2x and the domain (-5, -1, 0, 5, 7). To find the range of this function, we need to evaluate it at every point in its domain, which gives us the following values:
f(-5) = (-5)² - 2 × (-5) = 25 + 10 = 35
f(-1) = (-1)² - 2 × (-1) = 1 + 2 = 3
f(0) = (0)² - 2 × (0) = 0
f(5) = (5)² - 2 × (5) = 25 - 10 = 15
f(7) = (7)² - 2 × (7) = 49 - 14 = 35
The range of the function is therefore the set of all possible output values, which are 3, 0, 15, and 35. Therefore, the range of this function is {3, 0, 15, 35}.
We can use the same method to find the range of the other functions in the questions. The ranges of the other functions are:

What is the value of 7 9 of 45 answer?
The complete and simplified answer to the question what is 7/9 of 45 is 35.
The number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Any number can be converted to fraction if you use 1 as the denominator:
45 / 1
So now that we've converted 45 into a fraction, to work out the answer, we put the fraction 7/9 side by side with our new fraction, 45/1 so that we can multiply those two fractions.
All we need to do is convert the whole number to a fraction and then multiply the numerators and denominators.
7 × 45 / 9 × 1 = 315 / 9
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 315 and 9 is 9.
We can now divide both the new numerator and the denominator by 9 to simplify this fraction down to its lowest terms.
315 / 9 = 35
9 / 9 = 1
When we put that together, we can see that our complete answer is:

It says to ‘solve each system of equations using substitution
To solve a system of equations using substitution, you can start by solving one of the equations for one of the variables, such as x or y. For example, in this case, we can solve the first equation for x by subtracting y from both sides, like this:
[tex]-x - y = 1[/tex]
[tex]-x = 1 - y[/tex]
Now that we have an expression for x in terms of y, we can substitute that expression into the second equation to solve for y. When we do that, we get:
[tex]y = -(1 - y) + 4[/tex]
[tex]y = -1 + y + 4[/tex]
Now we can rearrange the terms on the right-hand side to make it easier to solve for y:
[tex]y = y + 4 - 1[/tex]
And when we combine the y terms on the left-hand side, we get:
[tex]2y = 3[/tex]
Finally, we can solve for y by dividing both sides by 2, like this:
[tex]y = 3 / 2[/tex]
Once we know the value of y, we can substitute it back into any of the original equations to solve for the other variable, x. In this case, if we substitute the value of y into the first equation, we get:
[tex]-x - y = 1[/tex]
[tex]-x - (3 / 2) = 1[/tex]
We can solve for x by rearranging the terms on the left-hand side and then dividing both sides by -1, like this:
[tex]-x = -1 + (3 / 2)[/tex]
[tex]x = (1 - 3) / 2[/tex]
Therefore, the solution to the system of equations is x = -1 and y = 3/2.
It's important to check your solution by substituting the values of x and y into the original equations to make sure they work. For example, if we substitute x = -1 and y = 3/2 into the first equation, we get:
[tex](-1) - (3 / 2) = 1[/tex]
And if we substitute the same values into the second equation, we get:
[tex](3 / 2) = (-1) + 4[/tex]
Both of these equations are true, which means our solution is correct.

y varies directly as x. when x = 5, y= 7, what is the value of y if x=10
Answer: y=14
Step-by-step explanation: y is directly proportional to x, meaning that multiplying x by a certain factor would also multiply y by that same factor. x=5 and y=7. If x changes to 10, it means that x is multiplied by a factor of (10/5) = 2. Therefore, y is multiplied by this same factor (2). As a result, 7*2=14
