The constant is the height over width
Answer:
0.40
Step-by-step explanation:
Find the z-scores.
z = (x − μ) / σ
z₁ = (18 − 23.5) / 3.6
z₁ = -1.53
z₂ = (25 − 23.5) / 3.6
z₂ = 0.42
Use a table or calculator to find the probability.
P(Z < -1.53) + P(Z > 0.42) = 0.0630 + (1 − 0.6628) = 0.4002
The probability is approximately 0.40.
The circle is closed when it is = and open when it is not = to the number that is being circled.
Complementary = angles add up to 90.
two angles are (x+3) and (4x-8)
Therefore:
90 = (x+3) + (4x-8)
Solve for x.
90 = (x+3) + (4x-8)
90 = 5x - 5
95 = 5x
/5 /5
19 = x
Therefore the value of x = 19
