Answer:
0.8745.
Step-by-step explanation:
P(success) = 0.09 and P(failure) = 1 - 0.09 = 0.91.
P( at least 6 failures) = P( less than 2 successes)
= 7C0 (0.09)^0 (0.91)^7 + 7C1 (0.09)(0.91)^6
= 0.5168 + 0.3577
= 0.8745.
Let y = total cost of the taxi service.
let x = amount of miles
We need to create a system of equations to solve this problem.
Taxi company 1: y = $0.25x + $5
Taxi company 2: y = $0.50x + $1
Set the equations equal to each other
$0.25x + $5 = $0.50x +$1.
Subtract $0.25x from both sides and subtract $1 from both sides.
$4 = $0.25x
Divide both sides by $0.25.
16 miles = x
The companies will charge the same amount of money at 16 miles
Answer: idk if there’s any specific choice, but it should be the case.
Step-by-step explanation:
if n^2 is divisible by 3, n must also be divisible by three, since its squaring n by itself. probably a bad explanation. 3^2 is 9, 9^2 is 81, 12^144. all of them are divisible by three. Basically think of it as: 9^2 is (3x3)^2. 12 is (3x4)^2. So if n^2 is divisible by 3, n should also be divisible by 3. Sorry for the bad explanation. also I hope it’s right, sorry if it’s wrong.
So for each hour the price increases $5.15
so 4 hours = 23.95
5 hours = 23.95 + 5.15 = 29.10
6 hours = 29.10 + 5.15 = 34.25
22% I hope it helps you I'm not positive I'm not the best but she was 22 numbers away from getting it right so
