check the picture below.
a positive slope, means an increasing slope, namely, a line that is higher from left-to-right, so the right tip of it is going upwards. A negative y-intercept,
now, if you notice the 3 green lines, the line is increasing, the right-side is higher than the left-side, and the y-intercept, namely where x = 0, or where the graph touches the y-axis, their y-intercept is on a negative value of y.
now, look at the red line, it has also a positive slope, is increasing, however, there's no way it can have negative y-intercept. If it remains increasing, it can only have a y-intercept of 3 or higher, but not lower than that. The only way it can have a negative value for the y-intercept is if it tips over, but if we do that, the slope will be decreasing.
First, add together the costs for buying their own stuff. 250+135+69+25=479.
Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
There is a 13.3% chance that a sample of 200 U.S. students in grades 9 through 12 who attend public and private school will have 11% or fewer obese students if 13.7% of the population is obese this year. (Option D)
<u>Explanation:</u>
From the given information it is observed that the 2013 national Youth Risk Behavioural Survey reported that 13.7 percent of US students in grades 9 through the grade 12 who attended the public school were obese.
Consider the random sample of 200 US students and find that 11 percent are obesed. The Null and alternative hypothesis are
Null hypothesis, = 0.137, Alternative hypothesis, = p less than 0.137
Thus, the value of p is 0.133
Answer: The slope is 80.75.
Step-by-step explanation: You just use the formula for rise over run.
The answer : It rotates around
