Answer:

A red 5 is chosen from the deck. The card is put back into the deck and the a red card is chosen.

Step-by-step explanation:

An independent event is one whose outcome is not dependent on any other event. There are two types of cards in the deck. If a red card is selected it will be from the series 1 - 20, if the card is put back into deck and then again a red card is selected it will be again from the series 1 - 20. This is an independent event since its outcome is same irrespective of the events.

This is an independent event since its outcome is the same irrespective of the events.

Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on the other.

If a variable is taking its values independently of any visible direct cause, then that variable is called an independent variable.

The variables that take their values based on some other variables' values are called dependent variables.

A deck of 40 cards contains 20 blue and 20 red cards. Each color has cards numbered 1 to 20.

This is an independent event since its outcome is the same irrespective of the events.

Answer:

The proof is done in the step-by-step explanation below.

Step-by-step explanation:

We are given the following identity:

[tex]\frac{\sin{A}\tan{A}}{1-\cos{A}}[/tex]

And we have to show that this is equals to:

[tex]1 + \sec{A}[/tex]

Multiplying numerator and denominator by the conjugate of the denominator:

[tex]\frac{\sin{A}\tan{A}}{1-\cos{A}} \times \frac{1+\cos{A}}{1+\cos{A}}[/tex]

[tex]\frac{\sin{A}\tan{A}(1+\cos{A})}{1 - \cos^2{A}}[/tex]

We use these following identities:

[tex]\sin^2{A} + \cos^2{A} = 1[/tex]

So

[tex]1 - \cos^2{A} = \sin^2{A}[/tex]

Also:

[tex]\tan{A} = \frac{\sin{A}}{\cos{A}}[/tex]

Then

[tex]\frac{\sin{A}\sin{A}(1+\cos{A})}{\cos{A}\sin^2{A}}[/tex]

[tex]\frac{\sin^2{A}(1+\cos{A})}{\cos{A}\sin^2{A}}[/tex]

[tex]\frac{1 + \cos{A}}{\cos{A}}[/tex]

[tex]\frac{1}{\cos{A}} + \frac{\cos{A}}{\cos{A}}[/tex]

[tex]\frac{1}{\cos{A}} + 1[/tex]

Since:

[tex]\sec{A} = \frac{1}{\cos{A}}[/tex]

We have that:

[tex]1 + \sec{A}[/tex]

Thus, the proof is done.

Answer:

52.6, 84.4

Step-by-step explanation:

Chebyshev's Theorem guarantee that we will find at least 89% of smoking males in the life expectancy range [52.6, 84.4].

In probability theory, Chebyshev’s inequality guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean.

Let X be a random variable with mean μ with a finite variance σ², then for any real number k > 0, P(|X-μ| < kσ) ≥ 1-1/k².

Given,

Mean life expectancy = μ = 68.5 years

Standard deviation = σ = 5.3 years

P(|X-μ| < kσ) ≥ 1-1/k²

P(|X-68.5| < 5.3k) ≥ 1-1/k²

P(|X-68.5| < 5.3k) ≥ 0.89

[tex]1 - \frac{1}{k^{2} } = 0.89[/tex]

[tex]\frac{1}{k^{2} } = 0.11\\ \\\frac{1}{k^{2} } = \frac{1}{9} \\\\k = 3[/tex]

Between the following two life expectancies does Chebyshev's Theorem guarantee that we will find at least 89% of smoking males:

= [μ - 3σ, μ + 3σ]

= [68.5 - 3*5.3, 68.5 + 3*5.3]

= [52.6, 84.4]

Answer:

851,968

Step-by-step explanation:

26*8*8*8*8*8= 851,968

From the combination of codes, 851,968 employee ID codes can be generated.

Given,
Employee ID codes can be generated.
Each code will have one letter followed by five digits. The digits 2 and 6 will not be used. So, there are 26 letters and 8 digits that will be used.
The number of employee codes to be determined.

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In a combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

Required number of  codes = 26 * 8 * 8 * 8 * 8 * 8
                                         = 851,968

Thus, from the combination of codes, 851,968 employee ID codes can be generated.

Step-by-step explanation:

step 1. shifting f(x) up by one simply adds 1 to f(x).

step 2. if g(x) = x^2 then f(x) = x^2 + 1.

The equation of the function f(x) is f(x) = x²+1

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given is a function g(x) = x², and a function f(x) which have the same graph as the function g(x) = x², but it is shifted up 1 unit, we need to find the equation of the function f(x),

we are given that, it is shifted up 1 unit, that mean it has horizontal shift,

Rule for horizontal shift =

k(x) = k(x) + a [for upwards]

So, horizontal shift of 1 = g(x)+1

Therefore, f(x) = g(x)+1

or, f(x) = x²+1

Hence, the equation of the function f(x) is f(x) = x²+1
