Answer:
The probability of exactly 2 breakdowns next month = 0.08422
Step-by-step explanation:
To calculate the probability of exactly 2 breakdowns next month, we use Poisson distribution formula.
P(X = x) = (e^-λ)(λˣ)/x!
Mean = λ = 5 breakdowns per month
x = 2 breakdowns per month
P(X = 2) = (e⁻⁵)(5²)/2!
P(X = 2) = 0.08422
Answer:
f(2) = 729
Step-by-step explanation:
f(x) = 3^(x + 4)
Let x =2
f(2) = 3^(2 + 4)
f(2) = 3^(6)
f(2) = 729
Answer:
51 meters
Step-by-step explanation:
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
We are to find the meters of fencing for the diagonal.
We solve the question using Pythagoras Theorem
= c² = a² + b²
Where
c = Diagonal
a = Width
b =Length
Diagonal² = Width² + Length ²
Hence:
Diagonal ² = 45² + 24²
Diagonal = √45² + 24²
Diagonal = √(2601)
Diagonal = 51 m
Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters
Answer: -258
<u>Step-by-step explanation:</u>
Given the sequence {-8, 16, -32, 64, ... , a₇} we know the following
- the first term (a₁) = -8
- the common ratio (r) = -2
- the number of terms (n) = 7
Input the information above into the Sum formula:
