Answer: 0.00067 minutes
Step-by-step explanation: if the proportion of customers who wait more than 15 minutes is 0.01, then the time interval between each waiting customer 15/0.01 = 1500 minutes.
The distribution that defines this question is that of an exponential.
An exponential distribution is dependent on the fixed time rate at which the event is occurring (λ)
For this question of ours, λ = 1500 minutes.
The mean of an exponential distribution is given as
u = 1/ λ = 1/1500 = 0.00067 minutes.
Hey there,
Solution:
Fabric needed = 1 3 / 4
Fabric she has = 4 5 / 8
1 3 / 4 - make the denominator into 8
1 3 / 4 = 1 6 / 8
Fabric left = 4 5 / 8 - 1 6 / 8
= 37 / 8 - 14 / 8
= 23 / 8
= 2 7 / 8
Hope this helps :))

Answer:
A) 0 (no solutions)
Step-by-step explanation:
Solve the equation:
3x - 10(x+2) = 13 - 7x
3x - 10x -20 = 13 - 7x
-7x - 20 = 13 - 7x
-20 = 13
Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
Answer:
2 7/24C
Step-by-step explanation:
Start by finding the common denominator. In this case, it's 24. Next, start translation.
2/3C = 16/24C
7/8C = 21/24C
3/4C = 18/24C
Then find the sum.
16/24C + 21/24C + 18/24C = 55/24C = 2 7/24C
B
the volume (V) of a sphere = 
πr³
We require to know the radius r to calculate the volume
using surface area of a sphere = 4πr² = 615.752
divide both sides by 4π
r² = 
= 49.0248...
take the square root of both sides
r = 
≈ 7, hence
V= × π × 7³ = 1436.76 m³ → B
