If n = 20, use a significance level of 0.01 to find the critical value for the linear correlation coefficient r.
Oliga [24]

Answer:

0.561

Step-by-step explanation:

To solve this problem we must resort to external information that I will leave attached with the answer, it is a table that for each value of n, gives us the critical values.

Returns the critical values ​​for both the significant levels of 0.01 and 0.05.

If we go to the table we know that when n = 20 and the significant level is 0.01, the corresponding critical value is: 0.561

Please help me if you can with this math problem
Viefleur [7K]

Answer:

m<BAC = 34

Step-by-step explanation:

It is given that (<BOC) is a central angle with a degree measure of (68). A central angle is an angle whose vertex is the center of the circle. (<BAC) is an inscribed angle, an angle whose vertex is on the circumference (perimeter) of the circle. Arc (BC) connects the ends of both of these angles.

The central angle theorem states that the measure of the central angle is equivalent to its surrounding arc. Using this theorem, one can state the following,

m<BOC = BC = 68

The inscribe angle theorem states that the measure of the arc surrounding the inscribed angle is twice the measure of the inscribed angle. Applying this theorem, one can state the following,

2(m<BAC) = (BC)

2 (m<BAC) = 68

m<BAC = 34

An analyst for a new company used the first three years of revenue data to project future revenue for the company. The analyst p
Westkost [7]

Using limits, it is found that since \lim_{x \rightarrow \infty} f(x) < 0, the company is expected to operate at a loss, hence it is not expected to be successful.

The revenue function is given by:

f(x) = -2x^5 + 6x^4 - x^3 + 5x^2 + 6x + 50

<h3>Limit:</h3>
  • The projected revenue over the long-term is given by the limit of f(x) as x goes to infinity.

Then:

\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} -2x^5 + 6x^4 - x^3 + 5x^2 + 6x + 50 = \lim_{x \rightarrow \infty} -2x^5 = -2(\infty)^5 = -\infty

Since the limit is negative, the company is expected to operate at a loss, hence not being successful.
