ANSWER:
In short, The population of price differences (woman – man) is normally distributed, or the sample size is large. population of price differences is normally distributed.
The data provide convincing evidence that, on average, women pay more than men in the county for the same car model.

I think the options were omitted, so i will go ahead and solve. From my answer, you can choose the right option
Answer:Equation to solve the question
=Distance = Speed x time
=d= 0.6 x 30
Distance , d= 18 miles
Step-by-step explanation:
Step 1
Speed = distance / time
Therefore Distance = Speed x time
Given that speed = 0.6 miles per minute and
Time=30 minutes
Step 2
Distance ,d= 0.6 miles per minute x 30minutes
d= 0.6 x 30
= 18miles
Answer:
(-6,24)
Step-by-step explanation:
Answer:
Step-by-step explanation:
13x^2 + 56x + 75 = 4x^2 - 10x - 46
You need to first combine like terms, so subtract 4x^2 from both sides,
9x^2 + 56x + 75 = -10x - 46
then add -10x to both sides
9x^2 +66x + 75 = -46
then add -46 to both sides
9x^2 + 66x + 121 = 0
Then use the quadratic formula, ![x = \frac{-b+- \sqrt[]{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-b%2B-%20%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
So
a = 9
b= 66
c = 121
![x=\frac{-66+-\sqrt[]{66^2 - (4*9*121)} }{2*9}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-66%2B-%5Csqrt%5B%5D%7B66%5E2%20-%20%284%2A9%2A121%29%7D%20%7D%7B2%2A9%7D)
