Answer:
< 2 and < 3 are complementary
Step-by-step explanation:
< 2 and < 3 are complementary because since 1 and 2 are complementary and 1 is congruent to 3 that would mean that 1 and 3 are equal degrees, so you could replace one with 2 as shown here: < 1 and < 2 are complementary and < 1 is congruent to < 3, then < 2 and < 3 are complementary. Assume < 1, < 2, and < 3 do not equal 45 degrees.

<span>Interval between 2.6 minutes late and 8.2 minutes late is within 2
standard deviations of the mean (k =8.2â’5.4/1.4 =5.4â’2.6/1.4 = 2). By Chebyshev’s Theorem, at least 1 â’1/2^2 =3/4 of all flights, i.e. at least 75% of all flights arrive
anywhere between 2.6 minutes late and 8.2 minutes late.</span>

The answer is B
Step-by-step explanation:
75 + x = 90
First, Virginia had to write an equation to solve for x.
75 - 75 + x = 90 - 75
Second, Virginia used the subtraction property of equality to isolate x.
x = 15
Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.
75 + 15 = 90
Finally, she had to verify her answer
