Answer:
1/4
Step-by-step explanation:
The total number of students = 16
4 are freshman
Therefore,
The probability of choosing a freshman is 4/16 which reduces to 1/4
Answer: 90% of people getting married for the first time get married before age of 31.13.
Step-by-step explanation:
Given : The average age (
) for a person getting married for the first time is 26 years (U.S. News and World Report, June 6, 1994).
We assume that the ages for first marriages have a normal distribution with a standard deviation (
) of 4 years.
Let x be the age before that 90% of people getting married for the first time get married.
From z-table , the value corresponds to p-value of 0.90 is 1.28155.
Formula : 
Hence, 90% of people getting married for the first time get married before age of 31.13.
1.93x3=5.79 but were not done because you need to add tax. So simply multiply 5.79 by 0.5 which equals .2895 round to the nearest cent so .29 then add .29 to 5.79 6.08.
The .05 is the tax % because you always have to remember that a tax % out of 100 is . then whatever % if it's a single number like 1 or 2 then it's like.01 or .02 hen multiply by the full amount. But that isn't the final answer because that is the tax amount. So add it back to the full number. That's how I found the answer.
The answer is 6.08
Answer:
1). angle 3= 48° [by vertically opposite angle]
2). angle 4 = 132° [by linear pair]
3). angle 5 = 50° [angle 6 and angle 5 are complementary angles]
4). angle 8 =36° [angle 7 and angle 8 are complementary angles]
5). angle 6 = 31° [sum of angle on straight line is 180°]
6). angle 8=33° [sum of angles on straight line is 180°]
7). angle 9=40° [sum of angles of triangle is 180°]
8). angle 3= 30°[angle 9 and 12 are linear pair and 9 is part of the triangle. so, sum of all angle of triangle is 180° ]
9). angle 15= 80° [sum of angles of triangle is 180°]
10). angle 8=35° [sum of angles of triangle is 180°]
11). angle 7=66°[sum of angles of triangle is 180°]
12). angle 14=105° [Sum of angles of triangle is 180°]
13). angle 12=130°[by sum of angle is 180°we'll find 9 then by linear pair angle 12= 130°]
14). angle 8=55° [ angle 14 and 16 are equal by vertically opposite angles and angle 14+angle 8+angle 3=180°]
15). angle 15=90°[first find 7 and 9 by sum of 90°and sum 180° then sum of angles of triangle is180°]
16). angle 16=95°[angle 7 and 8 are complementary angles and angle 1 and 3 are equal by vertically opposite angles now we have our two angles of the triangle so we can find third angle because sum of angle of triangle is 180°]
