Step-by-step explanation:
The quadratic formula of a quadratic equation

We have the equation:

Substitute:

The number of cups will be equal to 496.
<h3>What is arithmatic progression?</h3>
The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression
Here we have the data:-
The bottom row has 61 cups
If there are 16 total rows
The number of the cups will be calculated as:-

Here a1 is first term 1
an is last term 2
n is the total number of the rows
By putting the values in the question we will get:-

Hence the number of cups will be equal to 496.

I’m thinking 120 because if they added ten to each that totals up to 20 and 140-20=120
Answer:
0.0110
Step-by-step explanation:
This is a Poisson distribution problem
Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = 3 automobiles per minute
x = variable whose probability is required = more than 9 automobiles in a minute
P(X>9) = 1 - P(X ≤ 9)
P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)
P(X < 9) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6) + P(X=7) + P(X=8) + P(X=9)
So, computing this one at a time, and summing it all up
P(X ≤ 9) = 0.99620
P(X>9) = 1 - P(X ≤ 9) = 1 - 0.99890 = 0.0110
