Answer:
Step-by-step explanation:
im guessing you need the equation of the circle?
plugging it into the standard circle equaition you would get (x+9)^2+y^2=1 and then you would just need to rearaange it into standard form
To round 0.472 to the nearest tenth consider the hundredths' value of 0.472, which is 7 and equal or more than 5. Therefore, the tenths value of 0.472 increases by 1 to 5.
So, the answer would be 0.5.

Answer:
18
Step-by-step explanation:
Let x represent smallest number and y represent second number.
We have been given that the biggest among three numbers is 2.4 larger than the smallest one. So biggest number would be 
.
We are also told that 15 times the smallest one is equal to 12 times the second and 10 times the third. We can represent this information in equations as:
Upon solving 2nd equation, we will get:
Therefore, the smallest number is 4.8.
The biggest number would be 
.
Upon substituting in equation (1), we will get:
Therefore, 2nd number would be 6.
Let us find sum of all numbers as:
Therefore, the sum of all 3 numbers would be 18.
Let x represents the number of dvds sold per day:
To complete the probability distribution table, you need to add all the probabilities given and deduct that to 1 so that you can get the probability of 5-9, applying what I have said:Probability of 5-9:= 1 - (0.1875+0.4375+0.1250) = 1 – 0.75= 0.2500
But the question is not asking for the probability of 5-9, but 5 or more. So deduct the .1875 to 1 since .1875 only represents 0-4.P(X>= 5) = 1 - 0.1875 = 0.8125
Answer:
x = 9
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.8x = 7.2
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 0.8: x = 9
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 0.8(9) = 7.2
- Multiply: 7.2 = 7.2
7.2 does indeed equal 7.2. ∴ x = 9 is a solution.
And we have our final answer!
