Which graph best represents the solution to 1/3x + 5= 5.5?
insens350 [35]

Answer:

Value of the unknown quantity for which from given equation we get true numerical equality is called root of that equation. Two equations are called equivalent when the multitudes of their roots match, the roots of the first equation are also roots of the second and vice versa. The following rules are valid:

1. If in given equation one expression is substituted with another identity one, we get equation equivalent to the given.

2. If in given equation some expression is transferred from one side to the other with contrary sign, we get equation equivalent to the given.

3. If we multiply or divide both sides of given equation with the same number, different from zero, we get equation equivalent to the given.

Equation of the kind ax+b=0, where a,b are given numbers is called simple equation in reference to the unknown quantity x.

An important factor in selling a residential property is the number of times real estate, agents show a home. A sample of 21 hom
Natalka [10]

Using the t-distribution to build the 99% confidence interval, it is found that:

  • The margin of error is of 3.64.
  • The 99% confidence interval for the population mean is (19.36, 26.64).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

\overline{x} \pm t\frac{s}{\sqrt{n}}

In which:

  • \overline{x} is the sample mean.
  • t is the critical value.
  • n is the sample size.
  • s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 21 - 1 = 20 df, is t = 2.086.

The other parameters are given as follows:

\overline{x} = 23, s = 8, n = 21

The margin of error is given by:

M = t\frac{s}{\sqrt{n}} = 2.086\frac{8}{\sqrt{21}} = 3.64

Hence the bounds of the interval are:

\overline{x} - M = 23 - 3.64 = 19.36

\overline{x} + M = 23 + 3.64 = 26.64

The 99% confidence interval for the population mean is (19.36, 26.64).
