Answer:
m-9=42
Step-by-step explanation:
An amount subtracted by $9 is $42.
(an amount is unknown, so it is represented with variable, m)
m-9=42
Using first the customary ruler and then the metric ruler, measure the length of the side of the wooden block. Remember to estimate to one place value beyond the rulers’ gradations.
The volume of the composite figure is 3532.5 cubic inches
<h3>How to determine the volume of the composite figure?</h3>
From the given figure, we have the following dimensions:
- Height, h = 15 inches
- Radius of small cylinder, r = 5 inches
- Radius of large cylinder, R = 10 inches
The volume of a cylinder is
V = πr^2h
So, the volume of the composite figure is
V = πR^2h - πr^2h
Substitute the known values in the above equation
V = 3.14 * 10^2 * 15 - 3.14 * 5^2 * 15
Evaluate the product
V = 3532.5
Hence, the volume of the composite figure is 3532.5 cubic inches

Answer:
0.057258
Step-by-step explanation:
From the statement of the problem, the following information were given:
- P(Positive|HIV)=0.979
- P(Negative|No HIV)=0.919
- P(HIV)=0.005
The following can be derived:
- P(Positive|No HIV)=1-P(Negative|No HIV)=1-0.919=0.081
- P(No HIV)=1-P(HIV)=1-0.005=0.995
We are to determine the probability that a person has HIV given that they test positive. [P(HIV|Positive)]
Using Baye's theorem for Conditional Probability
The probability that a random person tested has HIV given that they tested positive is 0.057258.
Answer:
pi is the answer, because it goes on for every
Step-by-step explanation:
Examples of Irrational Numbers. An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
