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.
Answer:
Random, because he surveyed 30 <em>random</em> shoppers
Answer:
-7
Step-by-step explanation:
-8 = (-1/4)(4) + b
-8 = -1 + b
b = -7
The corresponding segments WX and ZY in the image are parallel.
When a shape is translated from location to another, the size and shape of the figure do not change. Therefore, lines that are corresponding are still parallel.
