<h3>
Answer: Choice B) 3:1</h3>
=============================================================
Explanation:
Consider a very small town of only 4 people.
If 1 person bikes to work, then 1/4 = 0.25 = 25% of the population commutes by bicycle. We see that the remaining 4-1 = 3 people don't travel by bike.
The odds against selecting someone who uses their bike to get to work is 3:1 which is why the answer is choice B
We list the number of people we don't want first, and then the number of people we do want (those who use a bike). A colon separates the two values to form the odds ratio.
We can say "3:1" as "3 to 1". It means we're 3 times more likely to select someone we don't want vs someone we do want. The odds are against the bike person which is why the value we don't want is listed first.
In contrast, if your teacher asked "what are the odds in favor of selecting someone who commutes by bicycle?" then the answer would be 1:3. We simply swap the positions of what we set up earlier.

Answer:
The equation of the line is <u><em>y = 3x - 1</em></u>
Step-by-step explanation:
In this question, we are asked to write the equation of the line using a point on the line and the slope of the line.
Mathematically, the slope-intercept form of a line can be written as;
y = mx + c
where m is the slope of the line and c is the y-intercept of the line. Now back to the question, we can see that we have all that is required for the line asides the value of the y-intercept <u><em>C</em></u>
To get this, we plug the values in the question into the equation of the straight line.
Here, we say y = 2, x = 1 and m = 3
2 = 3(1) + c
c = 2-3
c = -1
Thus, the equation of the line is y = 3x - 1
Answer: $13200
Step-by-step explanation:
If 100 square feet of roofing is installed for a cost of $1,200
1,100 square feet would cost $Z (let the unknown cost be Z)
i.e 100 ft^2 = $1,200
1100 ft^2 = $Z
Hence, to get the value of Z, cross multiply
Z x 100 = 1200 x 1100
100Z = 130000
Divide both sides by Z
100Z/100 = 1320000/100
Z = $13200
Thus, $13200 is the cost to have 1,100 square feet of roofing sheet installed
24 * 1/2 pint = 12 pints
1 pint = 16 ounces
1 pint (12) = 16 ounces (12)
12 pints = 192 fluid ounces
A) 192 fl oz
