Answer:

Step-by-step explanation:

Given

Probability of finding oil at site 1 is 0.30

Probability of finding oil at site 2 is 0.15

Probability of finding oil at site 3 is 0.20

Probability of Finding oil at all three sites

i.e. oil is present in all three sites simultaneously

=0.3\times 0.15\times 0.20=0.009

Probability of not finding oil at any of these sites=(1-0.3)\cdot (1-0.15)\cdot (1-0.2)=0.476

Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites

i.e. A'\cap B'\cap C'

Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

A\cup B' \cup C' or

'\cup B \cup C' or

A'\cup B' \cup C

Explain how finding 7×20 is similar to finding 7×2,000 . then Find each product
3241004551 [841]
7x20=140. 7x2000=14000. The only thing that changes the product of these numbers is the amount of zeros behind the 2. Since the only two numbers that affect the answer is the 7 and the 2. (7x2=14). The number of zeros behind the 2 affect how many zeros will be included in the product.

A small company 's net income for the first 6 months of the year was 76.500 and for the last six months it was 100,000 . What is
inna [77]

Answer:The ratio of net income in the first 6 months, to the last six months is $76,500 / $100,000. This simplifies intuitively as follows:

76500/100000

Dividing by 100: 765/1000

Dividing by 5: 153/200

The denominator 200 is only divisible by the prime numbers 2 and 5, and since the numerator 153 is not divisible by either 2 or 5, this means that this is in simplest form, and the final answer is 153/200.

Step-by-step explanation:i did the research for you this isnt my own answer therefore don't give me the credit. but hope this helped you tho :D

If you are going 200 miles per hour how much are you going per minute
Lapatulllka [165]

1 hour has 60 minutes.

Divide miles per hour by 60 to get miles per minute:

200 / 60 = 3.33 ( 3 1/3 ) miles per minute.

The sum of two confescutive integers is at least 46. What is the least possibly pair of integers?
dezoksy [38]
An integer is a whole number. Sum means to add and since they are consecutive, there is only a difference of 1 between them.

1) 21 + 23: not consecutive
2) 23+24= 47: has to be at least 46
3) 22+23= 45: has to be at least 46
4) 24+25= 49: has to be at least 46

So we have two possibilities: either #2 or #4. Find least possible pair of integers.

x= first integer
x+1= second integer

x + (x+1) >= 46
2x + 1 >=46
2x>=45
x>=22.5

Answer:
The first integer has to be greater than or equal to 22.5. Since integers are whole numbers, round up to the next whole number. The least possible integers are #2) 23 and 24.

Hope this helps! :)
