Answer:
22 units
Step-by-step explanation:
The formula for the area of a trapezoid is A = where a and b are the <u>bases</u> and h is the <u>height</u> of the trapezoid.
In this case, the numbers that will be replacing a and b will be 4 and 7, making the equation look like this: A = .
Now, you have to determine the height of the trapezoid, which in this case is 4 units. The equation will now look like this: A = .
You can solve from here like so:
A =
A = 5.5(4)
A = 22
sorry that took long :3))
I got the measurements like 4, 7, and the other 4 from rotating the shape to have the longer side on the bottom.
Trick question. For the reflections given in the problem statement, the x-coordinate doesn't change. The number that goes in the green box is 1.
Answer:
x=11/5
Step-by-step explanation:
isolate x
22/10 = 10x/10
22/10 = x
simplify
11/5 = x
The probability of picking 2 white balls and 1 black ball is 0.154
<h3>How to determine the probability?</h3>
The given parameters are:
- Number of balls, n = 20
- White = 12
- Black = 8
When each ball is selected, the total number of ball decreases by 1 and the type of ball also decreases.
So, the probability is represented as:
P(2 white and 1 black) = White/n * White - 1/n - 1 * Black//n - 2
Substitute known values
P(2 white and 1 black) = 12/20 * 11/19 * 8//18
Evaluate
P(2 white and 1 black) = 0.154
Hence, the probability of picking 2 white balls and 1 black ball is 0.154
