Jasmine was interested in how many days it would take an order from Netflix to arrive at her door. The graph below shows the data she collected. a. How many movies did she order? b. What percentage of the movies arrived in one day?

Answer:

Let X1,X2,...,Xn be i.i.d. random variables with expected value EXi=μ<∞ and variance 0<Var(Xi)=σ2<∞. Then, the random variable

Zn=X¯¯¯¯−μσ/n−−√=X1+X2+...+Xn−nμn−−√σ

converges in distribution to the standard normal random variable as n goes to infinity, that is

limn→∞P(Zn≤x)=Φ(x), for all x∈R,

where Φ(x) is the standard normal CDF.

Answer:

\(8^{20}\)

Step-by-step explanation:

using the rule of exponents

\((a^m)^{n}\) = \(a^{mn}\) , then

\((8^5)^{4}\) = \(8^{5(4)}\) = \(8^{20}\)

we have that

The zero is a reference point

so

+3 means -----> 3 units at the right of point x=0 (move forward) ----> final point x=3

-1 -----> 1 unit at the left of point x=3 (move backward) -----> final point x=2

-2 -----> 2 units at the left of point x=2 (move backward) ----> final point x=0

+1 ---->1 unit at the right of point x=0 (move forward) ----> final point x=1

Graph the moves

The first move -----> +3

Second move

-1

Answer:

11

Step-by-step explanation:

      a₁ = 1

     aₙ ₊ ₁ = (aₙ)² - 5

When n = 1 ; a₁+₁ = (a₁)² - 5          {Substitute the value of a₁}

                        a₂ = 1² - 5

                            = 4

When n = 2 ; a₃ = (a₂)² - 5           {Substitute the value of a₂}

                          = 4² - 5

                           = 16 - 5

                          = 11

Answer:

\(\textsf{a)} \quad f(x)=2x^3+4x^2-26x+20\)

\(\textsf{b)} \quad f(x)=-3x^3+6x^2-27x+54\)

Step-by-step explanation:

If f(x) is a polynomial, and f(c) = 0, then (x – c) is a factor of f(x).

Given information:

According to the factor theorem the polynomial in factored form is:

\(f(x)=a(x-(-5))(x-2)(x-1)\)

\(f(x)=a(x+5)(x-2)(x-1)\)

To find the value of the leading coefficient, a, apply the condition:

\(\begin{aligned}f(3)=a(3+5)(3-2)(3-1)&=32\\a(8)(1)(2)&=32\\16a&=32\\a&=2\end{aligned}\)

Therefore, the factored polynomial is:

\(f(x)=2(x+5)(x-2)(x-1)\)

Expand the polynomial:

\(f(x)=2(x^2+3x-10)(x-1)\)

\(f(x)=2(x^3-x^2+3x^2-3x-10x+10)\)

\(f(x)=2x^3+4x^2-26x+20\)

Given information:

According to the factor theorem the polynomial in factored form is:

\(f(x)=a(x-(-3i))(x-3i)(x-2)\)

\(f(x)=a(x+3i)(x-3i)(x-2)\)

To find the value of the leading coefficient, a, apply the condition:

\(\begin{aligned}f(1)=a(1+3i)(1-3i)(1-2)&=30\\a(1-9i^2)(-1)&=30\\a(1-9(-1))(-1)&=30\\-10a&=30\\a&=-3\end{aligned}\)

Therefore, the factored polynomial is:

\(f(x)=-3(x+3i)(x-3i)(x-2)\)

Expand the polynomial:

\(f(x)=-3(x^2-9i^2)(x-2)\)

\(f(x)=-3(x^2+9)(x-2)\)

\(f(x)=-3(x^3-2x^2+9x-18)\)

\(f(x)=-3x^3+6x^2-27x+54\)

The area and perimeter of the parallelogram are: 56 square units and 30 units respectively

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The parameters that will help us do the math are

base = 7

height = 8

Area = 8*7 = 56 square units

perimeter 2b + 2h

perimeter = 2*7 + 2*8

= 14 +16

P = 30 units

Therefore, the perimeter of the parallelogram and area are 30 units and 56 square units

Given system:

The first expression is ready to be substituted as no further operation is required to simplify it.

Find x:

Answer:

Step-by-step explanation:

step one:

Given the function

y = 14 +2.31x + 4.50

we can solve for the rate of change by applying differentiation.

step two:

differentiating y which is cost with respect to x which is the miles

dy/dx= 0+2.32+0

dy/dx=2.32

Hence the rate of change of cost in the dollar to a mile is

2.32dollar/mile

Answer to Question 1:

A way you can prove that the slope (m) = -2 is to write the equation:

3x + 2y + 7 = 5x + 3y + 10 in Slope-intercept form (y=mx+b). So all you need to do is solve for y. You will see that it will be y = -2x - 3. Step-by-step on how to solve it is in the image below. The coefficient of x is the slope (m), which is -2. So, it is proved that the slope is -2.

Answer:

f(x) = - 6x + 9

Step-by-step explanation:

y - 6x - 9 = 0
y - y - 6x - 9 = 0 - y
-6x - 9 = -y
y = 6x + 9
f(x) = 6x + 9

Step-by-step explanation:

The intervals in which the function is decreasing. \([-\pi , -\frac{\pi }{3} ], [\frac{\pi }{3}, \pi ]\). Option 3

We're given a function f(x) = 2 sin x - x, which describes a curve on a graph. We want to find the intervals where this curve is decreasing (going down) within the range of -π to π.

To find when the function is decreasing, we look at its slope. The slope tells us if the curve is going up or down. We find the slope by taking the first derivative of the function: f'(x) = 2 cos x - 1.

We now have an equation for the slope, f'(x) = 2 cos x - 1. A negative slope means the function is decreasing. So, we want to find where f'(x) is less than 0 (negative).

We set up the inequality: 2 cos x - 1 < 0. We solve it to find the x-values where the slope is negative. The solution is cos x < 1/2.

From the inequality cos x < 1/2, we find the intervals within the range of -π to π where the function is decreasing. These intervals are [-π, -π/3] and [π/3, π].

The above answer is in response to the question below as seen in the picture.

Determine the interval(s) in \([-\pi, \pi ]\) on

Answer:

Theoretical  --- probability is based on expected or calculated results.

Experimental  --- probability is based on the actual recorded results of an  experiment.

Step-by-step explanation:

Theoretical assumptions are those hypotheses not proven to be real, whose probabilities of materializing depend on the future confirmation of the premises established. Thus, these theories are established based on different experiences and previous situations, or based on data still not scientifically proven.

Instead, the experimental results are those that have already been confirmed based on tests, tests and experiments that affirm or deny the previously established theories.
