Writing equations of lines
Valentin [98]

Step-by-step explanation:

Equation of straight line is y=mx+c

choose any two points on straight line

for me I choose:(-3,11) and (3,-1)

use these two points to find gradient,m.

m= (-1-11)/(3-(-3))

m= -2

now, y=-2x+c

choose any point on the straight line

I choose point (3,-1)

sub the point into the equation to find c

-1=-2(3)+c

c=5

equation: y=-2x+5

Distribution with a mean of 100 and standard deviation of 15...
anzhelika [568]
Use the z-score:
                                      112 - 100
For 112, the z-score is --------------- = 12/15, or 0.8.  
                                             15

Next, find the AREA under the standard normal curve TO THE LEFT OF 0.8.

Use either a z-score table or a calculator for this purpose.

Using my calculator, I found that this area is 0.532.  That places 112 in the 53rd percentile.

82 would be in a lower percentile:  the 12th percentile.

Let me know if you have questions about how to use a calculator to do these calculations.
