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

Find the height of a triangle with an area (A) of 35 square inches and base of 7 use the formula A= 1/2bh
slega [8]

Answer:

D. 10

Step-by-step explanation:

Since you divided by 2. You want to multiply to go back wards.

35×2=70

They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.

70÷7=10

now plug it in to see if the equation is right.

35= 1÷2 (7×10)
