Y = 8 and X is 5 that’s the answer to your question
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
55/100 can be simplified to 11/20
<h3>The volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter</h3>
<em><u>Solution:</u></em>
<em><u>The volume of a container varies jointly with the square of its radius, r, and its height, h</u></em>
Therefore,
<em><u>The container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic centimeters</u></em>
Substitute v = 377 and h = 10 and r = 6 in eqn 1
<em><u>What is the volume of a container with a radius of 4 centimeters and a height of 4 centimeters?</u></em>
Substitute k = 1.05 and r = 4 and h = 4 in eqn 1
Thus volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter
