12 ft - 2 ft = 10 ft
The rope is 10 feet long.
10 · cos 30° = 10 · √3 / 2 = 8.66 ft
x = 12 - 8.66 = 3.34 ft
Answer:
A ) 3.34 feet
Answer:
Option A
Step-by-step explanation:
Given data
We are told that the weight of the rabbit is 2.8 kilograms
We also want to convert from kilograms to grams
We know that 1kg= 1000 grams
Hence 2.8 kg= x gram
Cross multiply
x= 2.8*1000
x= 2800 grams
Hence the weight in grams is 2800grams
Option A is correct

Answer:
5(s+7) or (s+7)*5
Step-by-step explanation:
Read the question carefully when trying to do these problems. Whenever it states "sum" then you should automatically put the terms behind it (s and 7) together to add them together. This would look like s+7.
Next it says 5 TIMES the sum of the terms therefore you should put s+7 together in parentheses and multiply them by 5 so that you first have the sum of s and 7 in parentheses. This would then look like 5(s+7) or (s+7)*5.
Answer:
The probability the man was hit by a Blue Cab taxi is 41%.
Step-by-step explanation:
In terms of bayesian probability, we have to calculate P(B|Wr), or, given the witness saw the right colour, the taxi is from the Blue Cab company.
According to Bayes
P(B|Wr) = P(Wr|B)*P(B)/P(Wr)
P(Wr|B) = 0,8
P(B) = 0.15
To calculate P(Wr), or the probability of the witness of guessing right, we have to consider the two possibilities:
1) The taxi is from Blue Cab (B) and the witness is right (Wr).
2) The taxi is from Green Cab (G) and the witness is wrong (Ww).
The total probality of guessing right is
P(B)*P(Wr) + P(G)*P(Ww) = 0.15*0.8 + 0.85*0.2 = 0.29
So we can calculate:
P(B|Wr) = P(Wr|B)*P(B)/P(Wr) = 0.8*0.15/0.29 = 0.41
The probability the man was hit by a Blue Cab taxi is 41%.
