You have that the scale factor is 8 and the length of the figure is 10 yards. Therefore, to solve this exercise, and calculate the length of the image, you must follow the proccedure below:
1. If the scale factor is 8, this means that lenght of the image is 8 times bigger.
2. Keeping this on mind, you only have to multiply 8 by 10 yards, as below:
Length of the image=8x10 yards
Length of the image=80 yards
3. Therefore, the answer is the option C:
C. 80 yd
For this case we propose a rule of three to obtain the number that represents 25% of 37.
So, we have:
37 --------> 100%
x -----------> 25%
Where "x" is the number that represents 25% of 37.
Finally, we have that 25% of 37 is 9.25.
Answer:
25% of 37 is 9.25.
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%.
If you simplify the expression, you will get A, E and D
Check the picture below. The perimeter? well, you can just count that off the grid, the area? same, but is just a 7x3 rectangle.
