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

Depth is 3.81

Step-by-step explanation:

V = l x w x d

11.43 = 2.5 x 1.2 x d

11.43 = 3 x d

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7) ?
vitfil [10]
Assume that f(5)=8. So, (5, 8) is a point in the graph of f.

For g(x) to give us 8, we need x to be 12, because in that case we would have:

      g(12)=f(12-7)=f(5), which is 8. Thus, (12, 8) is a point on the graph of g.


Comparing (5, 8) in f, and (12, 8) in g, we can see that the graph of g is the graph of f shifted 7 units to the right.


Answer: <span>C) The graph of g(x) is the graph of ​f(x)​ translated 7 units right.</span>

PLEASE HELP ASAP ): 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
eimsori [14]

Answer:

  c.  25

Step-by-step explanation:

(f ∘ g)(-2) = f(g(-2)) = f(-2-3) = (-5)² = 25

For this problem, it seems to work best to evaluate g(-2), then evaluate function f on that. (In other cases, it might be useful to simplify the composite function first.)
