Total students = 16
1. Total 9th graders = 3
Probability of being 9th grader = 3/16
2. Total that like comedy = 6
Probability = 6/16 = 3/8
3. 3 like action so 16-3 = 13 do not.
Probability = 13/16
4. 1 10th grader likes comedy out of 5 10th graders
Probability = 1/5
5. 0 out of 3 12th graders like comedy.
Probability = 0
6. 0 like action out of 3
Probability = 3/3 = 1
7. Yes the probabilities are different.

Answer:
(x² + 18) units²
Step-by-step explanation:
Area of a rectangle = l*w
There are two shaded rectangles found inside the large rectangle. Let us represent the smaller shaded one as Rectangle 1, the bigger shaded rectangle as Rectangle 2.
Below are the dimensions and area if each of them:
Rectangle 1 (small shaded rectangle):
l = x
w = x
Area = x * x = x² units²
Rectangle 2 (bigger shaded rectangle):
l = 9
w = 2
Area = 9*2 = 18 units²
Total area of the shaded rectangles = x² + 18 = (x² + 18) units²
Answer:
A. $4.45
B. $93.45
Step-by-step explanation:
A. first multiply: 89 x 0.05 = $4.45
B. add: $4.45 + $89 = $93.45
Step-by-step explanation:
Add 7 to both sides of the equation
3x^2=7
Divide each term by 3 and simplify
x^2 = 7/3
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x=±√7/3
The complete solution is the result of both the positive and negative portions of the solution.
x=√21/3 , −√21/3
The result can be shown in multiple forms.
Exact Form: x = √21/3 , −√21/3
Decimal Form:
x=1.52752523… , −1.52752523....
