The probability that a particular bulb will last from 2772 to 3298 hours is 2.66.

In mathematics, the term average is referred to as the mean value, which is equal to the ratio of the sum of all the values in a given set to all the values in the set.

Here we have been given,

A brand of lightbulb lasts on average 2821 hours with a standard deviation of 197 hours.

Assuming the life of the lightbulb is normally distributed, and we need to find the probability that a particular bulb will last from 2772 to 3298 hours.

According to the given problem, we know that the value of the following is defined as follows:

Average = 2821

Standard deviation = 197

Now, based on the z score concept, the value of the required probability is calculated as,

=> z = (x-mean)/ sd

=> z lower = (2821 - 3298)/197= -2.42

=> z upper = (2821- 2772)/197= 0.24

Therefore, the probability is calculated as,

=> z upper - z lower

=> 0.24 - (-2.42)

=> 2.66

Step-by-step explanation:

That's your answer

Answer:

y = (5e + 5sqrt(3) + 5) / (1 + (e + sqrt(3)) * e^(-t))

Step-by-step explanation:

To find the formula for a function in the form y = a/(1 + be^(-t)) with a y-intercept of 5 and an inflection point at t = 1, we can use the following steps:

Step 1: Find the value of a

Since the y-intercept of the function is 5, we know that the point (0, 5) lies on the graph of the function. So, we substitute t = 0 and y = 5 into the equation and solve for a:

5 = a / (1 + be^(0))

5 = a / (1 + b1)

5 = a / (1 + b)

a = 5*(1 + b)

Step 2: Find the value of b

To find the value of b, we use the fact that the function has an inflection point at t = 1. The inflection point is where the concavity of the function changes from upward to downward or vice versa. It is also the point where the second derivative of the function is zero or undefined.

The first derivative of the function is:

y' = -abe^(-t) / (1 + b*e^(-t))^2

The second derivative of the function is:

y'' = abe^(-t)(be^(-t) - 2) / (1 + b*e^(-t))^3

Setting t = 1 and y'' = 0, we get:

0 = abe^(-1)(be^(-1) - 2) / (1 + b*e^(-1))^3

Simplifying and using the value of a from Step 1, we get:

0 = 5be^(-1)(be^(-1) - 2) / (1 + b*e^(-1))^3

Multiplying both sides by (1 + be^(-1))^3 and simplifying, we get:

0 = 5b^2e^(-2) - 10b*e^(-1) + 1

Solving for b using the quadratic formula, we get:

b = (10e^(-1) ± sqrt(100e^(-2) - 451e^(-2))) / (25*e^(-2))

b = (2e + sqrt(4e^2 - e^2)) / (2e^(-1))

b = e + sqrt(3)

Step 3: Write the function in the form y = a/(1 + be^(-t))

Using the values of a and b from Steps 1 and 2, we get:

a = 5*(1 + b) = 5*(1 + e + sqrt(3)) = 5e + 5sqrt(3) + 5

b = e + sqrt(3)

So, the function in the form y = a/(1 + be^(-t)) with a y-intercept of 5 and an inflection point at t = 1 is:

y = (5e + 5sqrt(3) + 5) / (1 + (e + sqrt(3)) * e^(-t))

The vertices of the region are (7.2, -1.2) and (-2, 2).

In mathematics, an inequality is a statement that one quantity is less than or greater than another quantity. Inequalities are expressed using symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).

or example, "x > 5" means that x is greater than 5, while "y ≤ 10" means that y is less than or equal to 10.

Inequalities can be solved by isolating the variable on one side of the inequality symbol, just as with equations. However, there are some important differences between solving equations and solving inequalities. When solving an inequality, the direction of the inequality symbol may need to be reversed if both sides of the inequality are multiplied or divided by a negative number. In addition, the solution to an inequality is often expressed using interval notation or a number line.

To graph the system of inequalities, we first need to graph the boundary lines:

6y - x = 6 is equivalent to y = (1/6)x + 1, which has a y-intercept of 1 and a slope of 1/6.

y + 3x = -4 is equivalent to y = -3x - 4, which has a y-intercept of -4 and a slope of -3.

The region that satisfies both inequalities is the shaded region below the blue line and to the left of the red line.

To find the vertices of the region, we need to find the points where the two boundary lines intersect. Solving the system of equations:

y = (1/6)x + 1

y = -3x - 4

We get:

(7.2, -1.2) and (-2, 2)

Therefore, the vertices of the region are (7.2, -1.2) and (-2, 2).

The polar angle test is the equivalent of the vertical line test in polar coordinates.

Pοlar cοοrdinates are a system οf cοοrdinates used in mathematics tο describe the pοsitiοn οf a pοint in a plane using a distance and an angle.

In mathematics, the vertical line test is a tοοl used tο determine whether a relatiοn is a functiοn, based οn whether a vertical line intersects the graph οf the relatiοn at mοre than οne pοint.

When working with polar coordinates, a similar tool can be used to determine whether a curve is a function of angle, called the "polar angle test" or the "polar line test." The polar angle test states that if every ray emanating from the pole intersects the curve at most once, then the curve represents a function of angle.

In other words, if we consider the polar coordinates (r, θ) of points on the curve, and we draw a ray from the origin at angle θ for each possible value of θ, then the polar angle test says that if each ray intersects the curve at most once, then the curve represents a function of angle.

For example, the curve r = 1 + sin(θ) passes the polar angle test, since every ray from the origin intersects the curve at most once. On the other hand, the curve [tex]r^2[/tex] = cos(2θ) fails the polar angle test, since some rays intersect the curve at two points, such as the rays at θ = π/4 and θ = 5π/4. Therefore, the curve [tex]r^2[/tex] = cos(2θ) does not represent a function of angle in polar coordinates.

If line m parallel to line n, the value of y in terms of x is y = 3x + 10.

Let's consider the given information: a diagram with line m parallel to line n, and an angle (3x + 10)°.
Since line m is parallel to line n, we can use the properties of parallel lines and their transversals to find the relationship between x and y.

In this case, we'll use the property called alternate interior angles, which states that if two parallel lines are cut by a transversal, their alternate interior angles are congruent.
Identify the alternate interior angles.
Let's say the angle (3x + 10)° is an alternate interior angle to angle y°.

(B) r = 0.0804 * 100% = 8.04%

(C) value in 2009 = $11,650

What is the rate of change?

The rate of change is a mathematical concept that measures how much one quantity changes with respect to a change in another quantity. It is the ratio of the change in the output value of a function to the change in the input value of the function. It describes how fast or slow a variable is changing over time or distance.

A) The initial value is $44,000 and the final value is $15,000. The time elapsed is 2006 - 1992 = 14 years.

Using the formula for an annual rate of change (r):

final value = initial value * [tex](1 - r)^t[/tex]

where t is the number of years and r is the annual rate of change expressed as a decimal.

Substituting the given values, we get:

$15,000 = $44,000 * (1 - r)¹⁴

Solving for r, we get:

r = 0.0804

So, the annual rate of change between 1992 and 2006 was 0.0804 or approximately 0.0804.

B) To express the rate of change in percentage form, we need to multiply by 100 and add a percent sign:

r = 0.0804 * 100% = 8.04%

C) Assuming the car value continues to drop by the same percentage, we can use the same formula as before to find the value in the year 2009. The time elapsed from 2006 to 2009 is 3 years.

Substituting the known values, we get:

value in 2009 = $15,000 * (1 - 0.0804)³

value in 2009 = $11,628.40

Rounding to the nearest $50, we get:

value in 2009 = $11,650

Hence, (A) the annual rate of change between 1992 and 2006 was 0.0804

Answer:

Step-by-step explanation:

You want to know if the vertex is a minimum or maximum for functions ...

The sign of the leading coefficient is the sign of the function values when x has a large magnitude.

If the leading coefficient is positive, the parabola opens upward. Hence the vertex is a minimum. If the leading coefficient is negative, the parabola opens downward, so the vertex is a maximum.

The coefficient of the (x+1)² term is +1, so the vertex is a minimum.

The coefficient of the (x-2)² term is -1, so the vertex is a maximum.

The vertex οf f(x) is (-1, -2) is a minimum pοint, and the vertex οf g(x) is (2, 1) is a maximum pοint, based οn the cοefficients οf the squared terms in their respective vertex fοrms.

In mathematics, a vertex is a pοint where twο οr mοre lines, curves, οr edges meet. It can alsο refer tο the highest οr lοwest pοint οn a curve οr surface.

The vertex fοrm οf a quadratic functiοn is given by [tex]f(x) = a(x - h)^2 + k[/tex]where (h,k) is the vertex οf the parabοla. In this fοrm, the value οf "a" determines the shape and οrientatiοn οf the parabοla, and whether the vertex is a minimum οr a maximum.

Let's first rewrite the given functiοns in vertex fοrm:

[tex]f(x) = (x + 1)^2 - 2= 1(x - (-1))^2 - 2= 1(x - (-1))^2 + (-2)[/tex]

Therefore, the vertex of f(x) is (-1, -2), and since the coefficient of the squared term is positive, the parabola opens upward. This means that the vertex (-1, -2) is a minimum point.

[tex]g(x) = -(x-2)^2+1[/tex]

[tex]= -1(x - 2)^2 + 1[/tex]

Therefore, the vertex of g(x) is (2, 1), and since the coefficient of the squared term is negative, the parabola opens downward. This means that the vertex (2, 1) is a maximum point.

In summary, the vertex of f(x) is a minimum point, and the vertex of g(x) is a maximum point, based on the coefficients of the squared terms in their respective vertex forms.

Answer: To add the polynomials, we simply add the coefficients of the same degree terms. This gives:

(3x^2 - x - 8) + (7x^2 - 9x - 1) = 10x^2 - 10x - 9

Therefore, the sum of the polynomials is 10x^2 - 10x - 9.
