Hey there! I'm happy to help!
When working with percents, the word is means equals. Let's call our percent p and create an equation to solve.
46=141n
We flip equation so n is on the left.
141n=46
We divide both sides by 141.
n≈0.326241
To make this a percent, we move the decimal to the right two places, so our percent is around 32.6%.
Have a wonderful day! :D
Answer:
Ends up on the 5th floor
Step-by-step explanation:
10-9+19-3-12
(10+19)-(12+3+9)
29-24
5
Answer:
P(5R) = 0.60^5
P(5R) = 0.07776 = 0.078
Therefore the probability that it will be effective in each of five (5 out of 5) separate trials is 0.078
Step-by-step explanation:
Given;
The probability that the rhythm method of contraception is effective once is P(R) = 0.60
The probability that it will be effective n times is;
P(nR) = 0.60^n
For this case n= 5
P(5R) = 0.60^5
P(5R) = 0.07776
P(5R) = 0.078
Answer:
The sum is less than 5
The sum is odd
The sum is not 7
The sum is not 12
Step-by-step explanation:
P(The sum is less than 5) = 6/36 = 1/6
P(The sum is odd) = 18/36 = 1/2
P(The sum is not 7) = 1 - 6/36 = 30/36 = 5/6
P(The sum is not 12) = 1 - 1/36 = 35/36
