Answer:
156 barrels, 26 minutes
Step-by-step explanation:
The amount of minutes since the worker has started to work: x
Convertor: 26+5x
Worker: 6x
Since the question stated that the number of completed barrels are the same: 26+5x=6x
x=26
It has been 26 minutes and each line has 156 barrels filled out.
Hope this helps, please give brainlest if you are statisfied with this responce-it will help me a lot! Thanks!
Answer: not proportional
Step-by-step explanation:
The constant is called the coefficient of proportionality if one variable is always the product of the other variable and a constant. And the variables are said to be directly proportional.
In the given table , let the variables are proportional then the constant of proportion(k)=
=1.5
=1.45
⇒ k is not a constant of proportionality.
⇒ the variables x and y are not proportional.
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!!! :)
