The probability of spinning a red is 2/5
<h3>Probability</h3>
Probability is the likelihood or chance that an event will occur
- Probability = Expected/Total outcome
Given the following information
- Total number of spin = 30 spin
- Number of times it lands on red = 12 times
Pr(spinning a red) = 12/30
Pr(spinning a red) = 2/5
Hence the probability of spinning a red is 2/5

Answer:
1. 15.708
2. The radius would be half of the distance across the drain, or half of the diameter. Half of 3.8cm, or 3.8cm / 2 is 1.9cm.
The circumference is the distance around the drain, or if you trace the entire circle. The formula to find the circumference of a circle is 2 multiplied by pi and the radius of the circle, or C = 2(pi)r. Here, we just found the radius, so the circumference is 2 * pi (which is approximately 3.14) * 1.9cm, or approximately 11.9cm!
Step-by-step explanation:
Answer:
C. (x-2)^2=7
Step-by-step explanation:
What you have to do first is to get rid of the 3 in the x^2 so you will divide 3 by the whole thing to get x^2-4x=3.
You will then divide -4 by 2 and then square the answer to get 4.
You will then add the 4 into the end of the equation and to the 3 to get x^2-4x+4=7.
You will then make into a perfect square (x-2)^2=7 and that is your answer.
The second one
