Answer: 1/70
Step-by-step explanation:
This is a question that can also be interpreted as what is the probability of having the first number of a phone number to be 8 and the last number of the phone number to also be 8. This answer gives the fraction of the phone numbers that starts with 8 and end with 8.
Since three numbers (0,1,2) cannot start a phone number and we are left to pick from 7 numbers,
then the probability of figure "8" starting phone number = 1/7
Since all 10 numbers can possibly end a phone number,
then the probability of having figure "8" as the last digit of a phone number = 1/10
Hence probability of having "8" as the first and last digit of a phone number = fraction of total telephone numbers that begin with digit 8 and end with digit 8 = 1/7 × 1/10 = 1/70.
Since 30 times 5= 150, he worked 150 hours for the rest of the week.
Answer:
(x, y)→(x − 9, y − 3)
Step-by-step explanation:
We have given Hexagon DEFGHI is translated on the coordinate plane to create hexagon D'E'F'G'H'I':
We write the translation one by one:
D (3, 5)
D' (-6, 2)
that translates to: (x - 9, y - 3), because that is for passing from D to D':
(3 - 9, 5 - 3) = (-6, 2)
Now for E (7,5)
E' (-2,2)
that translates to: (x - 9, y - 3), because that is for passing from E to E':
(7 - 9, 5 - 3) = (-2, 2)
Now for F(8,2)
F' (-1, -1)
that translates to: (x - 9, y - 3), because that is for passing from F to F':
(8 - 9, 2 - 3) = (-1, -1)
therefore if it is true for D and D', E and E', F and F' then it has to be true for all others for the rule to be true, so the rule represents the translation of hexagon DEFGHI to hexagon D'E'F'G'H'I' is (x, y)→(x − 9, y − 3) ....
