Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in. To the nearest tenth of a percent, wha
Vinil7 [7]

Answer  

Find out the  percent error in Annie's estimate .

To prove

Formula

Percentage\ error = \frac{error\times 100}{exact\ value}

As  error = approx value -  exact value

As given

Annie estimates that the height of a bookcase is 78.25 in.

The actual height is 75.50 in.

approx value = 78.25 in.

actual value = 75.50 in.

error = 78 .25 - 75 .50

        = 2.75

put in the formula

Percentage\ error = \frac{2.75\times 100}{75.50}

Percentage\ error = \frac{27500}{7550}

Percentage error = 3.64 % (approx)

Therefore the Percentage error be 3.64 % (approx).

Two gamblers, call them Gambler A and Gambler B flip a coin repeatedly. The coin is unfair and comes up heads 2/3 of the time. G
Andru [333]

Answer:

≈ 0.52

Step-by-step explanation:

P( head ) = 2/3 , P( tail ) = 1/3

when a head is tossed ; Gambler A wins $1

when a tail is tossed : Gambler B wins $1

<u>Determine the P( Gambler A wins the game ) if he starts with I dollars</u>

Assuming I = $1

n = 5

p ( head ) = P( winning ) = 0.66

p( losing ) = 0.33

applying the conditional probability in Markov which is ;

Pₓ = pPₓ₊₁ + (1 - p) Pₓ₋₁

P( 1) = 0.66P₂ + 0.33P₀

resolving the above using with Markov probability

P( 1 ) = 0.51613

hence the probability of Gambler A winning the game if he starts with $1

≈ 0.52
