The answer is 7/69.
There are 8 black-haired children among 24 children. The probability of <span>randomly selecting black haired children for the first time is:
P1 = 8/24 = 1/3
Now, there are 7 black-haired children left among 23 children. The probability of </span>randomly selecting black haired children for the second time is:
P2 = 7/23
Since we want both of these events to occur together, we will multiply their probabilities:
P = P1 * P2 = 1/3 * 7/23 = 7/69
Answer:
Step-by-step explanation:
(Let the point where the altitude from intersects be called as point .) First, let's find the area of parallelogram . The area of a parallelogram is simply , where is the parallelogram's base and is the parallelogram's height. If we let and be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram will be .
Now, how does this information matter, you might ask? Well, we can take either <em>or </em> to be the base and either or to be the height. In this case, let's take the latter two options, as we are looking to find the length of .
Therefore, we know that the area of parallelogram can also be found by calculating . Since we know the values of the area and , we can write the following equation to solve for :
(Substitute and into the equation)
(Divide both sides of the equation by to get rid of 's coefficient)
(Simplify)
(Symmetric Property of Equality)
Hope this helps!
Slope y-intercept form is: y=mx+b
All you have to do is rearrange the equation:
2x-3y=6
2x=6+3y
2x-6=3y
now divide both sides by 3
(2x/3)-(6/3)=(3y/3)
and it becomes
x
Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!
You need a ruler and a pencil. Oh and paper. Make sure that each side is equal to 4 inches. Then make a scale of 1:12, meaning 1 inch=1 foot.
