Answer:
16 cm^2/min
Step-by-step explanation:
dV/dt=24
V=a^3, differentiate with respect to t
dV/dt=3a^2*da/dt, a^2*da/dt=8
S=6a^2, 216=6a^2. a=6. da/dt=(8/36)
dS/dt=12*a*da/dt=12*(8/6)=16 cm^2/min

0.35×(286,800÷100)
=1,003.8
The mean is 62 (496/8=62)
The median is 63 (52,52,52,62,64,69,69,76 take the two middle numbers and find the average 62+64/2=63)
The mode is 52 (there are three 52's)
The correct answer to this question is 1/5. To solve this, since 90 numbers exist in the range from 10 to 99, and 18 of them are divisible by 5, place these two numbers into the formula for probability.
Probability = target outcomes / total outcomes = 18 / 90
= 1/5
