The depth of the submarine, DDD, in feet below sea level, after ttt minutes have elapsed is given by the function D(t)=20+16tD(t)=20+16tD, left parenthesis, t, right parenthesis, equals, 20, plus, 16, t.

The pressure, PPP, in pounds per square inch, exerted on the submarine at a depth of xxx feet is given by the function P(x)=14.7+0.445xP(x)=14.7+0.445xP, left parenthesis, x, right parenthesis, equals, 14, point, 7, plus, 0, point, 445, x.

Find an explicit expression that models the pressure exerted on the submarine as a function of the elapsed time, ttt, in minutes.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
