Smith is a weld inspector at a shipyard. He knows from keeping track of good and substandard welds that for the afternoon shift, 5% of all welds done will be substandard. If Smith checks 300 of the 7500 welds completed that shift, what is the probability that he will find less than 20 substandard welds? Round to four decimal places.

z = 3.87

Step-by-step explanation:

learning abt this in school rn

lol

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
