Adoor-to-door salesman expects to make a sale 12% of the time when starting the day. but making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.38. if he makes no sale, the probability for a sale to the next customer stays at 0.12. what is the probability that he will make at least two sales with his first three visits?

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.

i'm pretty sure the answer is a. decreases with increase in
