Answer:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
Step-by-step explanation:
For this case we want to find the following probability:

And for this case we can use the normal standard distribution and the complement rule and we have this:

And i fwe look into the normalstandar dtable we can find the desired probability:

And then the The area to the right of z = 1.51 is 0.0655
The mass of the object would be 52.5g
Answer:
use desmos and type in the equation to get the graph
Step-by-step explanation:
That's the second one,
180 - x = r
Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.
The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.
You should go up 3.5 on the Y-Axis and then go up .5 and over 1.
