Leonardo wrote an equation that has an infinite number of solutions. One of the terms in Leonardo’s equation is missing, as show
Lady bird [3.3K]

Let us suppose missing term is y

so it becomes - ( x-1) + 5 = 2 ( x+3) - y

let us now try solving it for x ( in terms of y )

-x + 1 + 5 = = 2x + 6 - y

-x + 6 = 2x + 6 -y

6 + y = 2x + 6 +x

y = 3x

y / 3 = x

but x is given to be infinite . let us try placing y= the given options

x= x/3 which is not possible

x= 3x/3 which is giving valid statement

x= 1/3 which is a finite value

x= 5/3 again a finite value

so it is only y= 3x which could be the answer

Answer : option second that is 3x

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment. Find the margin of error for the 95% confiden
Vlad [161]

Answer:

The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.

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}.

The margin of error is of:

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

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.

This means that n = 2161, \pi = \frac{1214}{2161} = 0.5618

95% confidence level

So \alpha = 0.05, z is the value of Z that has a p-value of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

Margin of error:

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

M = 1.96\sqrt{\frac{0.5618*0.4382}{2161}}

M = 0.0209

The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.

Which ordered pair is included in the solution set to the following system?
Nataliya [291]

The ordered pair is included in the solution set to the following system is (0,2)

<h3>Set of inequalities</h3>

Given the set of inequalities

y > x2 + 1

y < x2 – x + 1

Equate both expressions to have:

x^2 + 1 = x^2 - x +1

1 = -x + 1

x = 0

Substitute x = 0 into any of the function

y = x^2 + 1

y = 1

This shows that the ordered pair is included in the solution set to the following system is (0,2)
