The probability is 0.25.
There are a total of 36 outcomes in the sample space for rolling 2 dice.
Out of these, there are 6 ways to get doubles (1 and 1, 2 and 2, 3 and 3, 4 and 4, 5 and 5, 6 and 6).
There are also 3 ways to get a total of 4: 1 and 3, 2 and 2, 3 and 1.
Together this gives us 9/36 = 0.25.
The standard equation of a circle is (x-k)²+(y-h)²=r², (h,k) is center of the center, r is the radius.
if the given two points form the diameter, find the midpoint of this diameter, the midpoint is the center of the circle. half the distance between these two points is the radius.
you can also use the third point to find the radius, by plugging the x and y values into the equation after you find k and h.
if either two of the three points form the diameter, plug the three different sets of x and y values in the equation. you have three equations with three unknown numbers h, k and r. solve to find h, k, and r.
Answer:
considering the fact that each person paints 1 wall. as 9 person's paints 9 walls then we can say it takes 41 min to paint a wall by a person then
it would take 41 min to paint 14 wall by 14 person
Answer:
4) 5
Step-by-step explanation:
3x-x+2=12
First, you combine similar terms, so 3x-x which is 2x.
Second, you subtract 2 on both sides which is going to give you 2x=10.
Finally, you divide by 2 on both sides, so the final answer is going to be x=5.
