A farmer from Whidbey Island: A man claims his whalebone can detect water. You design an experiment using a set of 4 cans, 3 emp
tatyana61 [14]

Answer:

The value is E(x) =  1.25

Step-by-step explanation:

From the question we are told that

The number of cans is n = 4

The number of can that are empty is N = 3

The number of can filled with water is k = 1

The number number of sets of cans is w = 5

Generally probability of detecting the correct can is mathematically represented as

p  =  \frac{k}{n}

=> p  =  \frac{1}{4}

=> p  = 0.25

Generally probability of not detecting the correct can is mathematically represented as

q =  1- p

q =  1- 0.25

q = 0.75

Generally the number of cans expected of the farmer to correctly identify by chance is mathematically represented as

E(x) =  w  *  p

=> E(x) =  5  * 0.75

=> E(x) =  1.25

So me and Patrick have the same IQ
JulsSmile [24]

Answer:

25 seconds

Step-by-step explanation:

The radius of a hailstorm varies directly

with the amount of time that it was in a cloud.

Radius = k x Time (in the cloud)

k is the constant of proportionality

R = k x T

0.5 = k x 10

k = 0.5/10

k = 0.05

Formula: R = 0.05 x T

1.25 = 0.05 x T

Time = 1.25/0.05

Time = 25 seconds.

Hope this helps :) !
