Mathematics: 1) the data in the table below represents the pressure of the gas as the temperature changes. plot a graph of the data, using the space below. draw a trend line and calculate its slope. how are the variables related? what will he pressure of the gas be at 0c? the graph looks like this temperature pressure 10 723 25 763 40 800 55 845 80 900

Step-by-step explanation:Since 40% of the crew are men, which means n. 40=8 n=8/. 40 n=20 total number of crew 20 - 8=12 are women...

The pressure of the gas 0°C is about 699.

Step-by-step explanation:

The given table of values is

Temperature Pressure

10 723

25 763

40 800

55 845

80 900

The general form of a trend line is

y=a+bx

where, b is slope and a is y-intercept.

$b=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}$

$a=\overline{y}-b\overline{x}$

Using graphing calculator, we get

a=699.006826

b=2.552218

The equation of line of best bit is

y = 2.552218x + 699.006826

where, y is pressure at x°C.

We need to find the pressure of the gas at 0°C.

Substitute x=0 in the above equation.

y = 2.552218(0) + 699.006826

y =699.006826

$y \approx 699$

Therefore the pressure of the gas 0°C is about 699.
