Which statement about the graph is true?
2 answers:
<h2>Answer:</h2>
The statement that is true about the graph is:
The graph does not show a proportional relationship because each point written as ratio gives a different value.
<h2>Step-by-step explanation:</h2>A graph is said to have a proportional relationship if it is a straight line passing through the origin.
i.e. a variable must be a constant multiple of the other variable.
i.e. y=kx
From the given graph we have a straight line that passes through (0,2) and (2,3)
Hence, the equation of line is:
Hence, the graph does not show a proportional relationship as the equation of the graph is not of the form y=kx
This means that
for some constant k.

<u>Answer:</u>
Below!
<u>Step-by step explanation:</u>
<u>We know that:</u>
- 400 + 850 + m = 1500
<u>Solution of Question A:</u>
<u>Percent of children: Total children/Total attendance</u>
- => 400/1500
- => 4/15
- => 0.27 (Rounded to nearest hundredth)
- => 0.27 x 100
- => 27%
<u>Hence, the percent of children is about 27%.</u>
<u>Solution of Question B:</u>
<u>Percent of women: Total women/Total attendance</u>
- => 850/1500
- => 85/150
- => 17/30
- => 17/30 x 100
- => 17/3 x 10
- => 170/3
- => 56.67%
<u>Hence, the percent of women is 56.67%.</u>
<u>Solution of Question C:</u>
- 400 + 850 + m = 1500
- => 1250 + m = 1500
- => m = 1500 - 1250
- => m = 250
<u>Percent of men: Total men/Total attendance</u>
- => 250/1500
- => 1/6
- => 0.17 (Rounded to nearest hundredth)
- => 0.17 x 100
- => 17%
<u>Hence, the percent of men is about 17%</u>
