slope intercept is basically solve for y y=mx+b m=slope b=yintercept -3x-10y=7 add 3x to both sides -10y=3x+7 divide both sides by -10
Answer:
y=x+1
Step-by-step explanation:
The slop and y-int are 1, just like on the graph
2)The goal is to isolate the variable and get is down to x<?. This is actually a two step inequality problem. 0.7x - 2 < 5.5 +2 +2 0.7x<7.5 This implies: x<10.714 The way to graph this is to place an open circle of the number 10.714 on the number line indicating this number is not included as a solution to the inequality. Then draw the arrow going left from the open circle indicating all numbers from -∞ to 10.714.
Answer:
B. Hannah is likely to be incorrect because 9 is not contained in the interval.
Step-by-step explanation:
She construct a 99% confidence interval for the difference between means and gets the interval (0.4, 8.0).
This means that there is 99% confidence that the true difference between means is within this interval.
The left 1% corresponds to the tails of the distribution: there is 0.5% probability that the difference between means is below 0.4 and 0.5% probability that the difference between means is above 8.0.
As she claims that 9 hours is the true difference, we can say that there is less than 0.5% that she is correct. In others words, is likely to be incorrect.
