What is the solution to this system of equations? 4x+y=6 x-2y=6

Step-by-step explanation:

267:(;»«=:3688865)):;(645789

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

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:

11.11

Step-by-step explanation:

Answer:

918.18

Step-by-step explanation:Formula = Number x 100

Percent = 101 x 100

11 = 918.18

Following shows the steps on how to derive this formula

Step 1: If 11% of a number is 101, then what is 100% of that number? Setup the equation.

101

11% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

11Y = 101 x 100

11Y = 10100

Y = 10100

100 = 918.18

Answer:

The 80% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars is (0.23, 0.27).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Suppose a sample of 768 new car buyers is drawn. Of those sampled, 192 preferred foreign over domestic cars.

This means that [tex]n = 768, \pi = \frac{192}{768} = 0.25[/tex]

80% confidence level

So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.95[/tex], so [tex]Z = 1.28[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.25 - 1.28\sqrt{\frac{0.25*0.75}{768}} = 0.23[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} =  0.25 + 1.28\sqrt{\frac{0.25*0.75}{768}} = 0.27[/tex]

The 80% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars is (0.23, 0.27).

Answer:

B. No. There is not a fixed number of trials

Step-by-step explanation:

Binomial random variable:

Can only have two outcomes(yes/no questions).

Each trial must be independent, that is, the probability of a success is always the same in a trial, and the number of trials is fixed.

It's probabilities must be between 0 and 1.

Is the number of passengers who pass through security in this time a binomial random variable?

For each person, there are only two possible outcomes. Either they are screened, or not. However, we don't want to know the number of people screened, which is binomial, we want to know the number of people until 10 are screened, which is inverse binomial. So, since there is not a fixed number of trials, this is not binomial, and the answer is given by option B.

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]

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.

Answer:

x= -1 , i(sqrt11) , -i(sqrt11)

Step-by-step explanation:

subtract 11x from both sides

-x^3 - x^2 - 11x = 11

subtract 11 from both sides

-x^3 - x^2 - 11x - 11 = 0

Factor the left side of the equation

- (x - 1)(x^2 + 11) = 0

Set both factors to zero and solve for x

x + 1 = 0 x^2 + 11 = 0

-1 -11

x^2 = -11

x = -1 x = +/- i(sqrt11)
