Answer:
A. 2006
Step-by-step explanation:
Given:
Number of male drivers model by equation
Number of female drivers model by equation
Where ⇒ the number of years since 1980
We need to find when will the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
Solution:
Now we can say that;
to find number of years when the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S we need to make both the equation equal we get;
Now Combining the like terms we get;
Now By using Division property dividing both side by 334.89 we get;
Now x is number of years after 1980.
So we can say that;
26 years after 1980 is 2006.
Hence Approximately in the year 2006 the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
GCF of 44 and 40 is 4
We need a total of 88 so the answer is:-
4(11 + 10)
Answer:
(a)0.0005
(b)0.2720
Step-by-step explanation:
Total Number of Transistors = 16
To find the probability that 4 selected at random are defective (or non-defective), we find the probability of the 1st, 2nd, 3rd, and 4th defective (or non-defective) items in that order, Note that the selection is without replacement.
(a)Probability that all are defective
Number of Defective Transistors =4
P(all are defective)
=0.0005
(b)Probability that none are defective
Number of Non-Defective Transistors =16-4=12
P(none are defective)
=0.2720
