Answer:
a)C
b)E
Step-by-step explanation:
a) You have to pick a vowel. There are three vowels and a total of 6 letters so it is 3/6 so the answer is C
b) Picking a card that is not T. None of the 6 letters are T so the probablity of picking a card with no T is 1. So the answer is E.
Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
Answer: perpendicular lines
Step-by-step explanation:
The total numbers with 10 digits are 9*10*10*10*10*10*10*10*10*10 = 9*(10^9)
If you are restricted to use no 1s, the numbers are 8*(9^9)
Then, the probability is : numbers with no 1s / total numbers
= 8*(9^9) / [9*(10^9)]= 0.344
