Two triangles are said to be congruent when the have the same sides and the same angles. When a figure is dilated by a value, the size of that figure changes.
Therefore, when Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle MꞌꞌNꞌꞌOꞌꞌ, the two triangles are similar but not congruent.
¹/₆(-15d + 6) < ²/₃(12d + 15)
¹/₆(-15d) + ¹/₆(6) < ²/₃(12d) + ²/₃(15)
-1¹/₂d + 1 < 8d + 10
+ 1¹/₂d + 1¹/₂d
1 < 9¹/₂d + 10
- 10 - 10
-9 < 9¹/₂d
²/₁₉(-9) < ²/₁₉(9¹/₂d)
⁻¹⁸/₁₉ < d
d > ⁻¹⁸/₁₉
Solution Set: {x ∈ x > ⁻¹⁸/₁₉}, (⁻¹⁸/₁₈, ∞)

Answer:
The probability that 25% or more in the sample speak Spanish is 76%.
Step-by-step explanation:
Sample of 75 Americans
If 25% or more in the sample speak Spanish, it can be deduced that 24% do not speak Spanish.
The proportion of those who do not speak Spanish is 18 (24% of 75)
Therefore, the proportion of those who speak Spanish is 57 (75 - 19)
This implies that 57/75 x 100 = 76% of the sample speak Spanish.
This 76% of the sample who speak Spanish is equal to the 25% or more who do speak Spanish in the sample.
Probability is the chance that an event may occur from many other events that could have occurred. It is an educated guess or estimate of something or one event happening when all the events in the set are given an equal chance.
