Step-by-step explanation:
So,
We are trying to find the compound probability of there BEING oil and the test predicting NO oil.
The percent chance of there actually being oil is 45%. We can convert this into fraction form and simplify it.
45% -->




That is the simplified fraction form.
The kit has an 80% accuracy rate. Since we are assuming that the land has oil, we need the probability that the kit predicts no oil.
The probability that the kit detects no oil will be the chance that the kit is not accurate, which is 20% (100 - 80 = 20). We can also convert this into fraction form and simplify it.
20% -->



That is the probability of the kit not being accurate (not predicting any oil).
To find the compound probability of there being oil and the kit not predicting any oil, we simply multiply both fractions together.



So the probability of there BEING oil and the kit predicting NO oil is 9 in 100 chances.
3/5 are not polka dotted, so first find 1/5. 20/5 is 4, so 1/5=4. 4x3 is 12 ribbons. Hope this helped!
Well he says he needs 16 inches of tubing for each washing machine and he is trying to install 18 washing machines.
sooo all we have to do is multiply 16 times 18
lets do the math:)
16 x 18 = 288
whats your answer? well its 288 inches of tubing
have a good one:)
merry christmas:D
