Answer:
7/2
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(7 1/2 - 7 1/2)² + [-2 1/2 - (-6)]²
√(0)² + (7/2)²
√49/4
= 7/2
Answer:
No
Step-by-step explanation:
In order for three sides to make a triangle, if any two sides are added together, their sum should be greater than the third side:
=><u> 5 + 7 = 12 < 13 (DOES NOT check off the rule)</u>
=> 7 + 13 = 20 > 5 (Checks off the rule)
=> 5 + 13 = 18 > 7 (Checks off the rule)
As shown, even though 2 of the statements check off the rule the third one does not, this means that the sides don't make a triangle.
Hope this helps!
Answer:
B. 93%
Step-by-step explanation:
Find the z-score:
z = (x − μ) / σ
z = (122 − 100) / 15
z = 1.47
Find the probability using a calculator or z-score table.
P(Z < 1.47) = 0.93
