Laura will go for a run during her lunch break if the temperature is between 6 0 ? f 60 ? f and 8 0 ? f 80 ? f. the average speed, s s, in miles per hour, at which laura runs is dependent on the temperature, t t, in degrees fahrenheit ( f ) ( ? f), at the start of her run and can be modeled by the function s ( t ) = 6 + 0 . 1 ( 8 0 ? t ) s(t)=6+0.1(80? t). the distance, d d, in miles, that she can run in 3 0 30 minutes given that her average speed is x x miles per hour can be modeled by the function d ( x ) = 0 . 5 x d(x)=0.5x. find an explicit expression that models the distance that laura runs in 3 0 30 minutes given that it is t ? f t ? f outside at the start of her run.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
