Answer:

115°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

Following this information we can conclude the measure of angle ACD:

40 + 75 = 115

Answer:

ACD = 115

Step-by-step explanation:

The interior angles of a triangle have to add up to 180, so add 40 and 75 then subtract it from 180.That would cause angle ACB to be 65. Angle ACD and angle ACB have to add up to equal 180. 180-65= 115, so angle ACD = 115.

Let X be a discrete random variable with geometric distribution.
Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
This function measures the probability P of obtaining the first success at the x attempt.
We need to know the probability of obtaining the first success at the third trial.
Where a success is defined as a customer buying online.
The probability of success in each trial is p = 0.3.
So:
P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
P (X = 3) = 0.147
The probability of obtaining the first success at the third trial is 14.7%
