Answer:
126
Step-by-step explanation:
The least common multiple of 7, 9, and 6 is the product of the unique factors.
7 = prime
9 = 3^2
6 = 3·2
The LCM is 7·3^2·2 = 126

Answer:
the 2nd one
Step-by-step explanation:
I had this problem on my test
The attached diagram represents the tree diagram for three consecutive mornings.
<h3>How to draw the tree diagram?</h3>
The probability of arriving on time is given as:
P(On Time) = 65%
Assume that the bus would definitely show up.
Then it means that the event is a binomial event and the possible outcomes are:
On Time and Late
The above means that the number of possible outcomes is 2.
For three consecutive mornings, the total outcome is:
Total = 2³
Evaluate
Total = 8
This means that the tree diagram would have 8 outcomes
Next, we draw the tree diagram (see attachment)

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
y ----> represent the pool’s loss of water
x ----> the number of days
a is the initial value
a=25,700 gal
b ----> is the base
r=15%=15/100=0.15
b=(1-r)=1-0.15=0.85
The function is equal to
