X=6 is the answer. good luck
Answer:
<h3>Finding averages.</h3><h3>Organizing data.</h3><h3>Estimating.</h3><h3>Data gathering.</h3>
Step-by-step explanation:
When we plan an effective budget, we certainly need to gather some data about the theme, which includes, prices, description of the stuff we need. Once we have the data we need, then we must organize it to set priorities, to make the budget effective.
Additionally, estiamting and finding averages are important skills, because we need to estimate how effective is the budget. In fact, maybe we would desing different budgets to compare them and analyse, using averages, which one is the most effective.
The formula of an area of a triangle:
We have:
substitute:
The formula of an area of a circle:
We have
Substitute:
The area of the shaded region
Answer:
Step-by-step explanation:
The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.
Formulas used:
- Area of a square with side length is given by
- Area of a circle with radius is given by
The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:
Area of square:
Area of circle:
Therefore, the probability that the point will be inside the circle is:
I think #4 is variable rate of change and #5 is D.
