Last year, Bob used 10 bottles of shampoo and 8 bottles of conditioner. His sister, Kayla, used 7 bottles of shampoo and 6 bottl

REY [17]

The lower ratio would be bob and that dude need to slow down the hair stuff

10 to 8 ratio is about 8.00
7 to 6 ratio is about 9.00

im not to good at math so dubble cheek just in case hope i could help tho

rip my spelling

if Amanda hikes at an average speed of 2.72 miles per hour, how long will it take her to hike 6.8 miles

kompoz [17]

Speed times time=distance
distance=6.8
speed=2.72
time=?

2.72 times ?=6.8
divide both sides by 2.72
?=2.5

answer si 2.5 hours

Ivan

Answer:

a) What is the probability that the duration of a particular rainfall event at this location is at least 2 hours?

We want this probability"

$P(X >2) = 1-P(X\leq 2) = 1-(1- e^{-0.367 *2})=e^{-0.367 *2}= 0.48$

At most 3 hours?

$P(X \leq 3) = F(3) = 1-e^{-0.367*3}= 1-0.333 =0.667$

b) What is the probability that rainfall duration exceeds the mean value by more than 2 standard deviations?

$P(X > 2.725 + 2*5.540) = P(X>13.62) = 1-P(X$

What is the probability that it is less than the mean value by more than one standard deviation?

$P(X$

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

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