Answer:
-0.25 ; 120 seconds 72 seconds
Step-by-step explanation:
Dive rate is constant :
Change in elevation after 8 seconds :
18 feets to 20 feets below
Rate of change = distance / time
(18 - 20) feets / 8 seconds
(-2 / 8) = - 0.25 feets per second
To reach 50.feets :
She needs to cover (50 - 20) = 30 feets
Time = distance / speed ; 30 feets / 0.25 = 120 seconds
Answer:
the answer is B the mean can't be greater than the median
The constant of proportionality (r) appears to be 3.
y = 3x . . . . . . . x = number of tickets sold; y = dollars collected
Well, 2.3•10^3 is the same as 2.3•1000. So move the decimal place three times to the right and you get a final answer of 2300.
