The first thing you need to do is classify all the men into 4 groups which are:
1) 30 and younger with facial hair: 4
2) older than 3 with facial hair: 5
3) 30 and younger with facial hair: 3
4) older than 30 without facial hair: 4
Question (a): Make a two-way table of the data. Of the men surveyed, how many were 30 and younger? How many did not have facial hair.
with facial hair without facial hair total
30 & younger 4 3 7
older than 30 5 3 8
total 9 6 15
From the data you can see that:
7 men were 30 and younger and 6 men did not have facial hair.
Question (b): Create a two-way relative frequency table that displays the relative frequency of the men 30 and younger and of the men older than 30 who had or did not have facial hair. Express your answer as decimals written to three decimal places.
with facial hair without facial hair total
30 and younger 4/15 3/15 = 1/5 7/15
older than 30 5/15 = 1/3 3/15 = 1/5 8/15
total 9/15 = 3/5 6/15 = 2/5 1
Question c: What percent of men older than 30 had facial hair?
The percent is equal to the relative frequency times 100% so in this case it is equal to (1/3) * 100% = 33.33%
Hope this helps!!! :)
Hello!
First you have to find how many liters of manure is made a day
1 cow makes 50 liters a day
We can do 50 * 1200 to find how many liters the cows make a day
50 * 1200 = 60000
Then you multiply this my how many days are in a month
60000 * 30 = 1800000
The answer is 1,800,000 liters of manure a month
Hope this helps!
1/64
0.015625 in decimal form
a reciprocal is the 1/whatever the number is
Transposition
Transposition is a method to isolate the variable to one side of the equation and everything else to the other side so that you can solve the equation.
Algebraic equations can be solved using the Law of equations. The Law of equations states that whatever you do on one side of an equation, you must do on the other side as well.
Answer:
30 times
Step-by-step explanation:
There's a 50% chance that they will get heads.
60 divided by 2 is 30
50% of 60 is 30
