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%.
Answer:
12a²-14a-48
Step-by-step explanation:
4a(3a-8) + 6(3a-8)
= 12a²-32a+18a-48
=12a²-14a-48
Answer:
-The increase in dollars is $1598
-The amount in her account at the end of last year was $8398.
Step-by-step explanation:
To find the increase, you have to multiply the initial amount for the percentage increase:
6800*23.5%=1598
Now, to find the amount in her account at the end of last year, you have to add the initial amount plus the increase in dollars:
6800+1598=8398
According to this, the amount in her account at the end of last year was $8398.
Answer:
Option 2 and option 5
Step-by-step explanation:
Option 2 because the common ratio of the sequence is dividing to half each element.
Option 5 because the common ratio is dividing by 5.
Remember that geometrical sequences are those where the common ratio is multiplying or dividing.
