A new aircraft control system is being designed that must be 98.0​% reliable. This system consists of two components in series.
sweet [91]

Answer:

98.99%

Step-by-step explanation:

The combined reliability of both components must be 98%. Given that both components must be functional and have the same reliability 'r', the minimum value of 'r' that meets the system requirements is given by:

0.98 = r^2\\r=0.9899=98.99\%

The level of reliability required for each component is 98.99%.

What is the slope of the line that cuts through the points (1, -5) and (3, 5)?
PolarNik [594]

Answer:

a. 5

Step-by-step explanation:

To find slope, subtract the y's.

5 - -5 is 10.

Put that on the top of a fraction.

Subtract the x's.

3 - 1 is 2, put that on the bottom of the fraction.

So the slope is 10/2. This simplifies to 5 (because 10÷2 is 5).

The slope is 5.

Kruka [31]

Answer:

  y = -2.8x +69.4

Step-by-step explanation:

The 2-point form of the equation of a line can be used to find the equation of the line through points (3, 61) and (13, 33). The general form of it is ...

   y = (y2-y1)/(x2-x1)·(x -x1) +y1

For the given points, this is ...

  y = (33 -61)/(13 -3)·(x -3) +61

  y = -28/10(x -3) +61

  y = -2.8x +69.4 . . . . . the equation of the line through the given points

<em>Comment on the problem</em>

A "line of best fit" is one that minimizes some measure of deviation from the line. Usually, what is minimized is the square of the deviations. Choosing two points to draw the line through may be convenient, but does not necessarily result in a line of best fit.
