Find the measure of each angle indicated. Show work.
Answer:
? = 109 degrees
Step-by-step explanation:
45 + 75 + _ = 180 ( look for vertical angles)
45 + 75 + 60 = 180
60 +79 + _ = 180 (look for a straight line that forms 180 degrees)
60 + 79 + 41 = 180
68 + 41 + _ = 180 (look for a triangle that adds up to 180)
68 + 41 + 71 =180
180 - 71 = 109 (look for a linear pair)

How can percents show proportional relationships between
quantities and be used to solve problems?
Answer:
By testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin
Step-by-step explanation:
Percentages are simply the measures of a quantity over a hundred (100), while proportional relationships are relationships that have a constant equivalent ratio
Solving proportional relationships using percentage
A proportional relationship is represented as:
[tex]y = kx[/tex]
Where k represents the proportionality constant, and x and y are the variables (or quantities).
Using percentages, then k has to be represented as a percentage.
Take for instance,
20 is 5% of 1007 is 5% of 140When the above instance are represented as a proportional relationship, we have:
[tex]y = 5\% \times x[/tex]
Such that
[tex]k = 5\%[/tex]

The statistic is the proportion of
Answer:
The population is: all glass recycled
The sample is: the 10 selected glass items.
The parameter is the proportion of: all his glass that is clear
The statistic is the proportion of: the selected glass that is clear
The population of a distribution is the entire group, while the sample is the selected group from the entire group.
The population is all glass recycled The sample is the 10 selected glass items. The parameter is the proportion of all his glass that is clear The statistic is the proportion of the selected glass that is clearThe population
From the question, we understand that glasses are recycled and then separated into colors.
This means that, the population is all glass recycled
The sample
From the question, we understand that he randomly grabs 10 glass items, and then determine the proportion of clear glasses.
This means that, the sample is the 10 selected glass items.
The parameter
This is the value that summarizes all the glasses that are being recycled.
So, the parameter is the proportion of all his clear glasses
