P ( A ) = 0.45 - probability that the land has oil,
P ( B ) = 0.8 - probability that the test predicts it
P ( A ∩ B ) = P ( A ) · P ( B ) = 0.45 · 0.8 = 0.36
Answer: The probability that the land has oil and the test predicts it is 36 %.
His average speed per minute is 1,448 meters per minute, and there are 60 minutes in a single hour. You would multiply 1,448 by 60 to get the answer of 86,880 meters per hour.
Hey there! :D
When a fraction is still divisible by a number, then it is not in it's simplest form.
For example, 3/6.
I know for a fact that 6/3=2 <== 3 is also divisible by itself.
3/6 (3/3=1) (6/6=1)
1/2 <== simplest form.
Try the same with 2/4.
4 is divisible by 2.
4/2= 2
2/2=1
1/2 is the simplest form.
I hope this helps!

Answer:
The answer to number 1 is 10. The answer to number 2 is 4-6, inclusive.
The total number of acorn squash that the farmer brought to the market = 80
Percentage of acorn squash was less when the day ended = 35%
Then
The amount by which the
number of acorn squash decreased at the end of the day = (35/100) * 80
= 280/10
= 28
Then
The number of acorn squash left with the farmer = 80 - 28
= 52
So from the above deduction, we can easily conclude that the farmer was left with 52 acorn squash at the end of the day.
