Answer:
Type of angle - Obtuse
Key information - 180° - 82° = 98° (missing angle)
Equation -
Step-by-step explanation:
Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.
then use the statement to solve for y and make it equal to 98°
= -12 subtract 12 from both sides
= 86 Now solve for y by dividing 86 ÷ 5
y = 17.2
Answer:
Probability = 0.1587
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ test for adults that is normally distributed with mean = 100 and standard deviation
= 15.
Also, US military has minimum IQ score of 85.
Thus, the probability that randomly selected adult does not meet US military enlistment standards is:
The probability can also be written as:
Thus,
Using the Normal probability table probability of Z = -1 is 0.1587
Thus, the required probability is 0.1587
