if p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, what is the cumulative probability of surviving for 3 years?

Answers

Answer 1

If p1, p2 and p3 are probabilities of surviving for years 1, 2 and 3 respectively, then the cumulative probability of surviving for 3 years is p1 + p2 + p3

The probability of surviving for 1 year = p1

The probability of surviving for 2 year = p2

The probability of surviving for 3 year = p3

The probability is the ratio of the number of favorable outcomes to the total number of outcomes.

The cumulative probability is defined as the probability distribution of random variables

The cumulative probability = p1 + p2 + p3

Therefore, the cumulative probability of surviving for 3 years is  p1 + p2 + p3

Heidi walks 3 miles per hour and chris walks 20,000 feet per hour. About how much faster is Chris walking than Heidi, in feet per minute?
(1 mile=5,280 feet)

Answers

Answer:

his gives us that Chris is walking 69 feet per minute faster than Heidi.

Step-by-step explanation:

1 mile is equal to 5,280 feet, we can multiply 3 by 5,280 to find that Heidi is walking 15,840 feet per hour.

Next, we need to convert both speeds to feet per minute. Since there are 60 minutes in an hour, we can divide both speeds by 60 to convert them to feet per minute. This gives us that Heidi is walking 264 feet per minute and Chris is walking 333 feet per minute.

Finally, to find out how much faster Chris is walking than Heidi, we can subtract Heidi's speed in feet per minute from Chris's speed in feet per minute.

Jasmine bought a fidget spinner for $3. She decided to mark up the price by 850% and sell it to her friend Bryan. How much did Jasmine sell the fidget spinner to Bryan for? Do not include the $ sign.

please help:)

Answers

Jasmine sold the fidget spinner to Bryan for the cost of $5.55.

To find the cost that Jasmine sold the fidget spinner to Bryan for, we need to first find the amount of the markup by multiplying the original price by the markup percentage.

As per the question, the original price of the fidget spinner is $3, and the markup percentage is 850%, so the markup amount is :

$3 × 850% = $2.55.

Next, we need to add the markup amount to the original price to find the selling price. So, the selling price is :

$3 + $2.55 = $5.55.

Therefore, Bryan paid $5.55 for the fidget spinner that Jasmine had just sold him.

Calculate the value of a for which the polynomial 2x^3 +7x^2 + ax + 2 has the root x = -2. Also, calculate the other roots of the polynomial.

Answers

The other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

What is polynomial?

A polynomial is an expression of one or more algebraic terms, each of which is composed of constants and/or variables raised to non-negative integer powers. A polynomial can be written in the form of an equation, where the coefficients of the terms form a sequence of numbers. Polynomials can also be expressed using a factored form, in which each of the terms is the product of a coefficient and a single variable or factor. Polynomials are commonly used to model real-world phenomena, such as the behavior of a system or process. The degree of a polynomial, which is the highest degree of the terms, determines the number of solutions it has. For example, a polynomial of degree two has two solutions while a polynomial of degree three has three solutions. The solutions of a polynomial are determined by solving the equation formed by the polynomial's terms.

Let us first rewrite the polynomial in a standard form:

2x^3 + 7x^2 + ax + 2 = 0
We can factor this polynomial using the Factor Theorem. The Factor Theorem states that if a is a root of a polynomial, then x-a is a factor of the polynomial.
Since x=-2 is a root of the polynomial, the factor (x+2) must be a factor of the polynomial.
Therefore, we can rewrite the polynomial as:
2x^3 + 7x^2 + ax + 2 = 2(x+2)(x^2 + bx + c)
Now, we can use the coefficients of the polynomial to solve for a, b and c.
Comparing the coefficients of the polynomial on both sides:
2 = 2c
7 = b
a = -2b-4c
Substituting the values of c and b in the equation for a, we get:
a = -2(b) - 4(2)
 = -2(7) - 8
 = -16
Therefore, the value of a is -16.
To find the other roots of the polynomial, we just need to solve the remaining factor (x^2 + bx + c) = 0.
Substituting the values of b and c, we get:
x^2 + 7x + 2 = 0
We can solve this equation using the Quadratic Formula:
x = [-b ± √(b^2 - 4ac)]/2a

Substituting the values of a, b and c, we get:
x = [-7 ± √(7^2 - 4(2)(2))]/2(-2)
 = [-7 ± √(49 - 16)]/-4
 = [-7 ± √33]/-4
Therefore, the other two roots of the polynomial are x = (7 + √33)/4 and x = (7 - √33)/4.

Twice a number is equal to negative four :

                       2n = -4

Equation:

An equation is a formula that expresses equality by connecting two expressions with an equal sign '='. Equations and their cousins ​​in other languages ​​may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, but in English any formula in its proper form consisting of two equations joined by an equal sign is an equation.

The equation resembles a weighted scale. When two bowls have the same weight (such as grain), the two weights balance the scale and are said to be equal. If you remove a certain amount of grain from one pan of the scale, you must remove the same amount of grain from the other pan to keep the scale balanced. More generally, the equation remains in equilibrium if the same operation is performed on both sides.

According to the question:

A polynomial function f is equal to x^3- 11x^2+41x- 51 of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.

The degree of this polynomial is 3 and the leading coefficient is 1. Three zeros are 3, 4+i, 4-i bc, and a-bi if a+bi is zero, also known as the conjugate postulate. With this information, we can say that the factors are (x-3)(x-(4+i) )(x-(4-i)).

When we start multiplying, we group like this

(x-3)( (x-4) + i )( (x-4) -i )

Multiply the second two factors first.

(x-4)^2 - (i)^2 [This is the difference of squares (a+b)(a-b)].

We know that

i^2 = -1

= x^2 -4x -4x +16 - (-1)

= x^2-8x+16+1

Answers

After solving we can conclude that (c) f(x) = -x is an odd function.

What is an odd function?

If -f(x) = f(-x), then a function f is said to be odd for all values of x.

When taking into account additive inverses, the functions even and odd are those that satisfy particular symmetry relations.

They are crucial to understanding power, the Fourier series, and mathematical analysis.

So, (a) f(x) = x³ + 5x² + x:

f(-x) = (-x)³ + 5(-x)² + (-x)

      = -x³ + 5x² - x

      = -(x³ - 5x² + x)

Neither even nor odd describe the function.

(b) f(x) = x² + x

f(-x) = (-x)² + (-x)

       = -(-x² + x)

Neither even nor odd describe the function.

(c) f(x) = -x

f(-x) = -(-x)

      = x

      = -f(x)

f(-x) = -f(x) makes the function odd.

2x + y = 7
-2x + 2y = -5

A. One Solution
B.Infinitely Many Solutions
C. No Solutions

Answers

Answer:

A. One Solution

Step-by-step explanation:

To determine if a system of equations has no solutions, infinitely many solutions, or exactly one solution, we can solve the system by any method, such as elimination or substitution.

In this case, we can solve the system by elimination. Multiplying the first equation by -2 and adding it to the second equation, we get:

0x + 4y = -3

This equation tells us that y must be equal to -3/4, but we still need to check if this value of y satisfies the original equations. Substituting -3/4 for y in the first equation, we get:

2x + (-3/4) = 7

Solving this equation for x, we get x = 5/4. Substituting this value of x and -3/4 for y in the second equation, we get:

-2(5/4) + 2(-3/4) = -5

which simplifies to:

-5/2 + (-3/2) = -5

This equation is true, so the solution of the system is x = 5/4 and y = -3/4. Since the system has a unique solution, the answer is (A) One Solution.

Show all work to identify the asymptotes and state the end behavior of the function f(x)=[tex]\frac{4x}{x-16}[/tex]
ILL MARK BRAINLIEST!! <3

Answers

Answer:

To find the asymptotes and the end behavior of the function f(x) = 4x / (x-16), we can first divide both the numerator and denominator by the highest common factor of 4x and (x-16). This gives us:

f(x) = (4x / 4x) / ((x-16) / 4x)

= 1 / ((x-16) / 4x)

Next, we can find the horizontal asymptotes by looking at the values of the function as x approaches positive and negative infinity. When x approaches positive infinity, the denominator of the function approaches 0, so the function approaches 1 / 0, which is undefined. Therefore, the function does not have a horizontal asymptote as x approaches positive infinity.

When x approaches negative infinity, the denominator of the function approaches -16 / -infinity, which is 0. Therefore, the function approaches 1 / 0, which is undefined. Therefore, the function does not have a horizontal asymptote as x approaches negative infinity.

Next, we can find the vertical asymptotes by setting the denominator of the function equal to 0 and solving for x. In this case, the denominator is (x-16) / 4x, so we can set each factor equal to 0 and solve for x:

x-16 = 0

x = 16

4x = 0

x = 0

Therefore, the function has two vertical asymptotes at x = 0 and x = 16.

How do I translate a function?

Answers

To horizontally translate a function,

1)substitute 'x-h' for 'x' in the function.

2)The value for 'h' controls how much the graph shifts to the left or right

3)In our example, since h = -4, the graph shifts 4 units to the left

4)To vertically translate a function, add 'k' onto the end

5)The value for 'k' controls how much the graph shifts up or down

You can also perform both horizontal and vertical translations on a function at the same time!

Translation

The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.

Answers

The probability that the mean number of lightning strikes per square kilometer is less than 5 is 0.0016, when  open ground in a year has mean 6 and standard deviation 2.4.

Define mean.

It imply a quantity that falls somewhere between the values of the extreme members of a set in mathematics. There are different types of means, and how they are calculated relies on the relationship that is known about or is regarded as governing the other members.

Given,

Mean = 6

Standard deviation = 2.4

The value that has been reduced by the population mean and divided by the standard deviation is called the z-value.

z = x - mean/ standard deviation/√n

z = 5 - 6/2.4/√50

z = - 2.95

Using table A, calculate the corresponding probability;

= P(x <5)

= P( z < -2.95)

= 0.0016

The probability that the mean number of lightning strikes per square kilometer is less than 5 is 0.0016.

How to find the amount the carnival committee should expect to pay?

At a booth at the school carnival in past years, they've found that 22% of students win a stuffed toy ($3.60), 16% of students win a jump rope ($1.20), and 6% of students win a t-shirt ($7.90). The remaining students do not win a prize.

If 150 students play the game at the booth, the amount of money the carnival committee expect to pay for the prizes of the booth is as follows:

total student that partake = 150

number that win stuffed toy  = 22% of 150

number that win stuffed toy = 33

number that win  jump rope = 16% of 150

number that win  jump rope = 24

number that win  t-shirt = 6% of 150

number that win  t-shirt = 9

Therefore,

prizes for those that win stuffed toy = 33 × 3.60 = 118.8 dollars

prizes for those that win jump rope = 24 × 1.20 = 28.8 dollars

prizes for those that win t-shirt = 9 × 7.90 = 71.1 dollars

Hence,

total amount the committee is expected to pay for prizes = 118.8 + 28.8 + 71.1 = 218.7 dollars

The sum of the 2nd and 3rd terms of an arithmetic sequence is 27 and the sum of the 4th and 5th terms is 77.

Answers

The sequence's average difference is 12.5.

According to the given information

The sum of an arithmetic sequence's second and third terms is 27.

The combination of the fourth and fifth terms is 77.

We must ascertain,

Let d represent the sequence's common difference.

The arithmetic series' second term is,

Second term = a + d

The arithmetic series' third term is as follows:

Third term = a + 2d

The second and third terms in the sequence add up to 27, thus.

Second term + third term = 27

a + d  + a + 2d  = 27

2a + 3d = 27

The arithmetic series' fourth term is,

Fourth term = a + 3d

The fifth term in the mathematical series is as follows:

Fifth term = a + 4d

The sequence's fourth and fifth terms add up to 77

Fourth term + fifth term = 77

a + 3d + a + 4d = 77

2a + 7d = 77

After resolving the two equations,

2a + 3d = 27

2a + 7d = 77

Subtracting both the equations

2a + 3d - ( 2a + 7d ) = 27 - 77

2a + 3d - 2a - 7d = -50

-4d = -50

d = 12.5

The sequence's average difference is 12.5
