Answer: It would be 6/4 miles or 1 1/2 miles
Step-by-step explanation:
Answer:
y= 2x + (-2)
Step-by-step explanation:
The algebraic formula y=mx+b can be broken down into mx, equaling slope +x, and b, which is the y intercept. Taking two points from the slope, you can see that the slope is 2, as the line moves up 2 on the y axis for every 1 move horizontally on the x axis. Additionally, we see that this particular line crosses the y axis at the point (-2), meaning that is the y intercept. Hope this can offer some assistance.

Answer:
a. Yes(n=500>=5, n(1-p)=25>=5)
b. 0.15241
Step-by-step explanation:
a. A normal approximation to the binomial can be used 5 and n(1-p)>=5:
#We calculate our p as follows:
=x/n=470/500=0.94
n=500
n(1-p)=500(1-0.95)=25
Hence, we can use the normal approximation.
b. This is a normal approximation.
-Given that p=0.95(95%)
-We verify if our distribution can be approximated to a normal:
Hence, we can use the normal approximation of the form:
Hence, the probability of the sample proportion is the same as the proportion of the sample found is 0.15241
