The total they paid is $23 because 1 of them bought 4 cookies for $2 each so we multiply 4 and 2 we will get $8 and the other girl bought 5 cookies for $3 each so we multiply 5 and 3 and that is $15 so we add $15 and $8 and we will end up with $23
<span>What is 3(6m) + m?
3(6m) + m =
m becomes 1m
9m + 1m =
10m
3(6m) + m is 10m when combining like terms. </span>
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.
Our two binomials are (X-5)(X-7)
If we FOIL those two terms [x*x = x2; x*-7 = -7x; x*-5 = -5x; -5*-7 = 35] and combine the like terms, we're left with one of many quadratic function
Answer
x2-12x+35
