What is the domain of the function?

1 answer:

Lesechka [4]4 years ago

3 0

Answer:

(2, ∞)

Step-by-step explanation:

The function is not defined to the left of x=2 (assuming the independent variable is x). There is a vertical asymptote at x=2, so the function is not actually defined for x=2. However, the function is defined for all values of the independent variable greater than 2, so that is its domain.

(We don't actually know what the indpendent variable is, so we have expressed the domain in interval notation—avoiding the problem of naming the independent variable.)

solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$

Step-by-step explanation:

We need to solve the following expression:

$-8\frac{3}{4}-11\frac{1}{3}$

Solving:

$-8\frac{3}{4}-11\frac{1}{3}\\ =-\frac{35}{4}-\frac{34}{3}\\=\frac{-35*3-34*4}{12}\\=\frac{-105-136}{12}\\=\frac{-241}{12}\\=-20\frac{1}{12}$

So, solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$

A random sample of 500 army recruits has a mean height of 68 inches with a standard deviation of 2.5 inches. if a 95% confidence

Komok [63]

Answer:

c) 0.22

Step-by-step explanation:

<u>Explanation</u>:-

A random sample of 500 army recruits has a mean height of 68 inches with a standard deviation of 2.5 inches.

The sample size 'n' = 500

Given the mean of the sample = 68 inches

Given standard deviation = 2.5 inches

$Margin error = \frac{Z_{\alpha } S.D}{\sqrt{n} }$

The 95% of confidence interval ∝ = 1.96

$M.E = \frac{1.96 X 2.5}{\sqrt{500} }$

Margin of error = 0.2191 ≅0.22

<u>Conclusion</u>:-

The Margin of error at 95% of confidence intervals = 0.22
