169/2209 OR 7.22%
Step-by-step explanation:
[probability that both have the secret decoder ring]=(13/47)*(12/46)
[probability that both have the secret decoder ring]=(156/2162)
[probability that both have the secret decoder ring]=0.0722-------> 7.22%
the answer is 0.0722 (7.22%)
Answer:
here is your description
Step-by-step explanation:
Scatter Plot one has a negative linear association, which means that the points are <em>arranged</em> in a <em>line</em> that is angled in a downward slope. Hence, the word "negative"
Scatterplot two has no association. The points have no pattern and are scattered around the graph.
hope this helps!
1. If the angles are congruent the measures are equal. That's the angle congruence postulate, usually too obvious to name.
2. The measures of complementary angles add to 90 degrees. That's the definition of complementary angles.
3. We substitute m∠2 for m∠1 so now m∠2 + m∠3 = 90 degrees.
4. The measures add to 90 degrees so now we conclude ∠2 and ∠3 are complementary.
------------
Why did this proof bother with the measures at all? Proof: Angles 2 and 3 are complementary. Angle 1 is congruent to Angle 3. Therefore Angles 1 and 3 are complementary.
