Sorry no one can answer this, there is no picture of the results of the survey
True.
If the two triangles line up perfectly they are congruent.
Hope this helps!
I think is
9 + x = 16 + 27
9 + x = 43
x = 52
The correct answer is true because the origin will always be (0,0)
Answer: −1.409
Step-by-step explanation:
Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013
Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118
Probability of other draw: 1 - 0.013 - 0.118 = 0.869
0.013 * (50 - 5) = 0.585
0.118 * (25 - 5) = 2.353
0.869 * (0 - 5) = -4.347
Expected value: 0.585+ 2.353 - 4.347 = -1.409
