An object is launched on the moon at 16 feet per second (f/s) from a 1152-foot tall tower. The equation for the object's height

alexgriva [62]

Answer:

0.5seconds later

Step-by-step explanation:

Given the height modeled by the equation:

s(t) = -16t^2 + 16t + 1152

The velocity of the object at the moon surface is zero

ds(t)/dt = 0

ds(t)/dt = -32t + 16

0 = -32t + 16

32 t = 16

t = 16/32

t = 1/2

t = 0.5seconds

Hence the object strikes the moon surface 0.5seconds later

The cashier service time at the local branch of the Rivertown bank has an exponential distribution with a mean of 2.5 minutes. W

aleksandrvk [35]

Answer: d. .2474.

Step-by-step explanation:

Given : The cashier service time at the local branch of the Rivertown bank has an exponential distribution with a mean of 2.5 minutes.

The cumulative distribution function for exponential distribution is :-

$P(X\leq x)= 1-e^{-\frac{x}{\lambda}}$

, where $\lambda$ = Mean of the distribution.

The probability that the service time is between 2 and 4 minutes will be :

$P(2\leq X \leq 4)=P(X\leq4)-P(X\leq 2)\\\\= (1-e^{\frac{-4}{2.5}})-(1-e^{\frac{-2}{2.5}})\\\\=e^{\frac{-2}{2.5}}-e^{\frac{-4}{2.5}}\\\\=0.449328964117-0.201896517995\\\\=0.247432446123\approx0.2474$

Hence, the correct option is d. .2474.
