The answer is if you convert. we cant see the number line so, we cant tell you the second part of the problem.. attach the image please.
ok so convert.. -13/4 becomes -65/20 and 2/5 becomes 8/20, so add that and get -57/20, then simplify how you want to. thats your answer
Answer:
5 < x < 13
Step-by-step explanation:
9+4 > x
4 + x > 9
The percent decrease in people going to the movies from Saturday to Sunday is 35.3%

0.1/0.5 is the same as 1/5
1/5 = X/10
we times both sides by 10 to get x on its own
1/5 x 10 = 10/5 = 2 ( which equals X/10 x 10)
X/10 x 10 = X
2 = X

To determine the regression:
Intercept
= 131760.9563
Slope
The regression line equation
We then make a comparison of the slope of the equation to y = mx+c
slope of the equation = -1.2600
the y-intercept corresponds to when X = 0, thus:
y-intercept = 131760.9563
Yes, it is reasonable to interpret the y-intercept of the regression line, Using atmospheric pressure as an explanatory variable due to the fact that:
X is the independent variable and Y exists as the dependent variable.
