Answer:
The statement true about the results of the survey is:
- <u>D. 48% of students preferred the seacoast</u>.
Step-by-step explanation:
To identify if the D option is right, you only must use a simple rule of three, where you use the total of the members surveyed in the club (150), and the number of members that preferred the seacoast (72), by the last the operation must confirm that this value (72) is equal to the 48% (how says in the D option). First, you must establish the rule of three:
- 150 = 100 (100% of surveyed really, but is easier to understand in this form)
- 72 = X
And operate:
- X= (72 * 100) / 150
- <u>X = 48 (this means the 48%)
</u>
How you can see, <em><u>the value obtained in the simple rule of three is exactly the percentage of the D option, for this reason, this is the true statement</u></em>.
It seems you already have answers. Do you want us to check it?

Step-by-step explanation:
goooooood luuuuucccckkkkkk
We have this equation for the slope is: y=mx+b which m is the slope and b is the y-intercept, so we have y=20-15x or y=-15x+20, and we already know that the slope is -15 and y-intercept is 20. As a result, the student's error is that he thinks that 20 is the slope because it is the first number. Hope it help!
