2. In the US, about half of all homes with a basement also have a sump pump. A plumbing company surveys 673 homeowners with basements, chosen through a random sample, and finds that of those 673,
there are 392 who own a sump pump. Does this survey constitute significant evidence evidence that
Chicago homes with basements have sump pumps at a higher rate than the average in the US? Use a
hypothesis test to support your findings.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
