weqwewe [10]

The equation for the season pass would look like:
y=25x+350
Daliy pass:
y=67x+25x or y=92x
x is the amount of days and y is the total cost.
92x=25x+350 This equation will be how many days the cost will be equal
67x=350
x=5.223
The skier would have to go up 6 days to start saving from the season pass

15 divided into 6396 show the steps on how to solve I know the answer is 42 just don’t know the step to put in order

exis [7]

First, you have to look at the 6. 6/15 does not form a whole number, so you have to move on to the number beside it. 63/15 is 4 with a remainder of 3.
Then you bring down the 9 next to the 3. 39/15 = 2 Remainder 9. The 6 is brought down next to the 9. 96/15 = 90 with a remainder of 6.
We no longer have any more numbers so, we bring down a zero in the the tenth place. 60/15 = 5, with no remainders.

Therefore, 6396/15 = 426.5

A building may fail by excessive settlement of the foundation or by collapse of the superstructure. Over the life of the buildin

patriot [66]

Answer:

0.1536

Step-by-step explanation:

The computation of probability that the building failure will occur over its life is shown below:-

P(building failure) is

$P(ES \cup C)\\\\ = P(ES) + P(C) - P(ES\cap C)\\\\ = P(ES) + P(C) - P(ES) P (C | ES)\\\\ = 0.12 + 0.06 - 0.12 \times 0.22$

now we will solve the above equation

= 0.18 - 0.0264

After solving the above equation we will get

= 0.1536

Therefore for computing the probability that the building failure will occur over its life we simply applied the above formula.
