1) This probability is given by

... C(40,5)·0.12⁵·0.88³⁵ ≈ 0.18665 . . . . . where C(n, k) = n!/(k!(n-k)!)

2) This probability is given by

... 0.88⁴⁰ ≈ 0.00602

3) This is the complement of the probability that all have failed.

... 1 - 0.12⁴⁰ ≈ 1.0000

Two functions are graphed on the coordinate plane. Which represents where f(x) = g(x)?
PilotLPTM [1.2K]
I think a word is missing here:  '<span>Which { ? } represents where f(x) = g(x)?

If the graph of f(x) intersects the graph of g(x), the coordinates of the point of intersection constitute the "solution" of f(x) = g(x).

If you were to share functions f(x) and g(x), you'd likely be able to determine the point of intersection, either algebraically or graphically.</span>

Please help tysm if you decide to help c:
erma4kov [3.2K]

Answer:

B

Step-by-step explanation:

Hello :)

The question is asking about true statements, so let's go through the choices.

A) The profit increased for all five months; this question means that the profit (money value) should have increased every month; while it does from June to September, October goes down so this statement is false.

B) This statement is saying June + 100,000 dollars+ =August. June's profit is approximately 150,000 lower than August so this is true.

C) This answer choice explains October's profit was less than June's; 298,000 from October is bigger than 248,000 from June so this is false.

D) I can't read off the last statement but no profit is drastically bigger than the other for it to be twice as much of September.

Answer:

- 328 / 9

Step-by-step explanation:

- 36 + ( - 4 / 9 )

= - 36 - ( 4 / 9 )

= - 36 ( 9 / 9 ) - 4 / 9

= ( - 36 x 9 ) / 9 - ( 4 / 9 )

= ( - 324 / 9 ) - ( 4 / 9 )

= ( - 324 - 4 ) / 9

= - 328 / 9
