Answer:

We will add 3 to each side of the equation

Step-by-step explanation:

x^2 − 8x + 13 = 0

We want to complete the square

We will subtract 13 from each side of the equation

x^2 -8x +13 -13 = 0 -13

x^2 -8x = -13

Then take the coefficient of x

-8

Divide by 2

-8/2 = -4

Square it

(-4)^2 = 16

Add this to each side

x^2 -8x +16 = -13+16

( x-4) ^2 = 3

The sum of subtracting 13 and adding 16 is adding 3

An experimenter flips a coin 100 times and gets 59 heads. Find the 98% confidence interval for the probability of flipping a hea
lara [203]

Answer:

The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).

Step-by-step explanation:

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

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

An experimenter flips a coin 100 times and gets 59 heads.

This means that n = 100, \pi = \frac{59}{100} = 0.59

98% confidence level

So \alpha = 0.02, z is the value of Z that has a p-value of 1 - \frac{0.02}{2} = 0.99, so Z = 2.327.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.59 - 2.327\sqrt{\frac{0.59*0.41}{100}} = 0.4756

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.59 + 2.327\sqrt{\frac{0.59*0.41}{100}} = 0.7044

The 98% confidence interval for the probability of flipping a head with this coin is (0.4756, 0.7044).

When f(x) is replaced with<br> f(x)+k, the graph that results is shown below <br> K=__?
serious [3.7K]

Answer:

k = 6

Step-by-step explanation:

Parent function of the given graph → f(x) = (x - 1)²

If the parent function is shifted 6 units up.

Equation of the translated function will be → g(x) = (x - 1)² + 6

g(x) = f(x) + 6

Therefore, k = 6 will be the answer.

I don't know how to plug in 1,5,10 for a function
castortr0y [4]

explanation:

in regular math: if the function is written as function notation, replace all x's in the expression with your number and solve.

in brainly: click the math button, {it looks like a square root sign with an x inside} press whichever function or process you like and in the text box it should say something like " /[operation]{x}{y} "

in those curly brackets around x and y is where your numbers should go. just get rid of the variable and put it in your number to make the function/process they way you want it to go instead of having those placeholder variables.
