The distance advanced in a day by a tunnel boring machine, in meters, is uniformly distributed on the interval (29, 50). Suppose the distances advanced on different days are independent. What is the probability the machine advances more than 45 meters on exactly four out of 10 days?

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.

step-by-step explanation:

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer

the answer is 9 because the question is telling how much it be together.
