A lumber company is making boards that are 2697.0 millimeters tall. If the boards are too long they must be trimmed, and if they

are too short they cannot be used. A sample of 25 boards is made, and it is found that they have a mean of 2697.4 millimeters with a standard deviation of 10.0 . Is there evidence at the 0.1 level that the boards are either too long or too short? Assume the population distribution is approximately normal.
a. Determine the decision rule for rejecting the null hypothesis.
b. Make the decision to reject or fail to reject the null hypothesis.

A vertical line that the graph of a function approaches but never intersects. The correct option is B.

<h3>When do we get vertical asymptote for a function?</h3>

Suppose that we have the function f(x) such that it is continuous for all input values < a or > a and have got the values of f(x) going  to infinity or -ve infinity (from either side of   x = a) as x goes near a, and is not defined at   x = a, then at that point, there can be constructed a vertical line  x = a and it will be called as vertical asymptote for f(x) at   x = a

A vertical asymptote can be described as a vertical line that the graph of a function approaches but never intersects.

Hence, the correct option is B.

Slope of 1,-7 and -3-4​
3241004551 [841]

\large \mathfrak{Solution : }

Slope of the given line is :

  • \dfrac{y_2 - y_1}{x_2 - x_1}

where ,

  • x_2 = 1

  • x_1 =  - 3

  • y_2 =  - 7

  • y_1 =   - 4

let's solve :

  • \dfrac{ - 7 - ( - 4)}{1 - ( - 3)}

  • \dfrac{ - 3}{4}

Slope = -3 / 4
