It may be observed from the given that the probability of the both Samantha and Judith scoring an A is the product of the individual probabilities of Samantha and Judith. This means that the events are independent. Thus, the answer is letter A.
13. (3/8)*q + 12 = 36
3q/8 = 24
3q = 192
q = 64
14. 3 - (3/4)n = 9
-3n/4 = 6
-3n = 24
n = -8
15. (7/9)v + 2 = 23
7v/9 = 21
7v = 189
v = 27
16. 7 + (1/8)l = -2
l/8 = -9
l = -72
17. (v/-3) + 8 = 22
v/-3 = 14
v = -42
18. 8x - 16 + 8x = 16
16x = 32
x = 2
19. 12a - 14a = 8
-2a = 8
a = -4
20. 7c - 8 - 2c = 17
5c = 25
c = 5
21. 6 = -y + 42 - 2y
-36 = -3y
y = 12
22. 16 + 8r - 4r + 4 = 24
20 + 4r = 24
4r = 4
r = 1
The answer would be 2x+y=0
Hope this helps
Have a great day/night

Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle
