ANSWER: 
(third option)
Answer:
And using the normal standard distirbution or excel we got:
Step-by-step explanation:
Let X the random variable that represent the resistance for resistors of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the z score formula is given by:
Using this formula we got:
And using the normal standard distirbution or excel we got:
You just add them :)
2x+7x+3y-3y=-5+9
3y and -3y is 0 which means this equals to 9x=4, so B
ANSWER
A) For all x > 0 the graph will be higher.
EXPLANATION
Jack's graph has equation
y=2x
This graph passes through the origin and has slope 2.
Nina's graph is y=5x.
This graph also passes through the origin and has slope 5.
Since 5 is greater than 2, for all x>0, Nina's graph will be higher.
