Answer:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.
Step-by-step explanation:
Let the time for which Grace jumps the rope = minutes
Let the time for which Zoe jumps the rope = minutes
As per question statement:
Number of times Grace jumps in one minute = 66
Number of times Zoe jumps in one minute = 56
Number of times Grace jumps in minutes = 66
Number of times Zoe jumps in minutes = 56
As per question statement:
Multiplying equation (1) with 66 and subtracting equation (2) from it:
By equation (1):
Therefore, the answer is:
Grace jumps for 9 minutes.
Zoe jumps for 12 minutes.
Answer: Probability of trucks having both defects is 4%.
Step-by-step explanation:
Since we have given that
Probability of trucks having defective brake linings only = 6%
Probability of trucks having defective steering only = 3%
Probability of trucks having neither defect = 87%
Probability of trucks having either defect - 100 - 87 = 13%
Let the probability of trucks having both defects be 'x'.
P(defective brake lining) = P(B) = 0.06+x
P(defective steering) = P(S) = 0.03+x
So, Probability of the trucks having both defects is given by
So, Probability of trucks having both defects is 4%.
