Answer:
-3/4, -2/5, -4/15
Step-by-step explanation:
using calculator, -3/4 = -0.75, -4/15 = -0.266666..., -2/5 = -0.40
imagine that -0.75, -0.26... and -0.40 are temperatures
the coolest temperature is -0.75, the warmest one is -0.26...
so the least number is -0.75, greater -0.40 and the greatest -0.26...
You should have put a picture so ppl would know what the question is askin
Answer:
The confidence interval based on the paired design is wider because there is little variation in mileage between the cars.
Step-by-step explanation:
The sample size randomly collected is matched sample and since the confidence interval is based on the paired design is large and wide. There is small variation between the mileage of the two cars indicating the cars have mileage based on the fuel.
First, let's expand the right side. Now our equation is

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

And then we can make this

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
