Answer:
C) $14.2
Step-by-step explanation:
$3 is flat value. minimum price. $0.8 per mile for 14 miles is 0.8x14 which equals to 11.2. Add $3 and get $14.2.
X+1825=y^2
sqrt(1825)=42.8
so the least is y^2=43^2=1849
so x=1849-1825=24
Answer:
8x + 5
Step-by-step explanation:
3 + 4x + 2 + 2x + 2x
3 + 2 = 5
4x + 2x = 6x
6x + 2x = 8x
Answer: 0.0123
Step-by-step explanation:
Given : Customers leaving a subway station can exit through any one of three gates.
The probability of selecting any particular gate = 
Sample size : n= 4
Using binomial distribution,
, where P(x) is the probability of getting success inn x trials , n is the number of trails and p is the probability of getting success in each trial.
Then , the probability that among a sample of 4 customers, they all exit through the same gate.

Hence, the probability that among a sample of 4 customers, they all exit through the same gate = 0.0123
